1.0 SUMMARY

J-J Minerals of Sudbury, Ontario, Canada was contracted by Plato Gold Corp. ("Plato") of Toronto, Ontario,

Canada to review the Good Hope Niobium Property (the "Property"), conduct geological mapping and

sampling, and to write an Assessment Report (the “Report”). This Report summarizes the current and

historic geological data on the Good Hope Niobium Property, Marathon, Ontario. The purpose of the 2017

prospecting was designed to confirm the historic sampling and identify new carbonatite and ijolite outcrops

with anomalous Niobium and Phosphorus. Hole PL-01 was relogged to confirm the presence of pyrochlore

and to better understand the geology of the Property.

The Good Hope Property is located approximately 45 km northwest of Marathon and 28 km north of

Highway 17. The Property is located in NTS sheet: 42E02SE and in the mining district of Thunder Bay

South. The Discovery Site Pit #1 is located at UTM Z16, 519637 m, N 5432636 m, NAD 83. The Property

is readily accessible from Trans-Canada Highway 17 and Deadhorse Creek Road.

The Good Hope Niobium Property consists of a total of 19 claims, 263 claim units and 4208 hectares in

Killala Lake Area and Cairngorm Lake Area Townships, northwest of Marathon, Ontario. Plato Gold Corp.

has an option agreement with Rudolf Wahl and other claim holders for the Property.

Within the Superior Province, numerous alkaline and carbonatitic rocks are distributed along the Trans-

Superior Tectonic Zone. Four alkaline rock carbonatite complexes have been identified along this Zone:

Coldwell, Chipman, Killala Lake and Prairie Lake. Both the Coldwell Complex and the Killala Lake

complex do not contain carbonatites, whereas Chipman Lake and Prairie Lake complexes do contain

carbonatites. The Good Hope Property claims surrounds the Prairie Lake Complex. The center of the Prairie

Lake Complex is not included in the Good Hope Property.

The Good Hope Property consists of paragneiss and metasedimentary rocks bedrock and alkali granite,

ijolite and carbonatite. The alkali granite shows variable degrees of fenitization and brecciation. Alkali

granite breccia has carbonatite veins/ matrix between the clasts. Three types of carbonatite are found on the

property: calciocarbonatite, ferrocarbonatite and silicocarbonatite.

The Property hosts Niobium mineralization in pyrochlore (a Nb-oxide mineral). The Niobium

mineralization differs from that in Prairie Lake Complex in that it is low in Th and U contents. Two

paragentic varieties of carbonatites were identified on the basis of mineral abundances and textures:

pyrochlore-rich and pyrochlore-poor. The pyrochlore-poor phase represents a later stage of crystallization.


Plato Gold Corp


The pyrochlore-rich carbonatite contains early crystallized cumulates of apatite and Na-Ca pyrochlore with

interstitial carbonate minerals.

The discovery of Niobium mineralization at Good Hope was made by Rudy Wahl in 2010 when he

identified 1.63 % Nb2O5 in a small outcrop on Site #28. In recognition of this Niobium discovery, Rudy

Wahl received the Bernie Schnieders Discovery of the Year Award for 2014 from the Northwestern Ontario

Prospectors’ Association (NWOPA).

Canadian International Minerals completed prospecting, rock sampling, radiometric surveys, soil sampling,

trenching and channel sampling in May to July 2011 on the Good Hope Property. The focus of the

exploration was the search for rare-earth elements (“REE’s”). Canadian International dug 12 trenches (TR-

11-PL-001 to TR-11-PL-012) on radiometric highs on the Property. A total of 238 channel samples were

collected from the trenches and sent for assay. Ten trenches were located along Deadhorse Creek Road on

claim 4256252 and two trenches were located on claim 4256251, at Site #28

In September to December 2014, Dr. Wahl followed up on his discovery with prospecting, hand stripping,

geological mapping and rock sampling in 5 pits that he dug within Site #28 on claim 4256251. A total of

17 samples were assayed for Nb2O5 % and P2O5 with up to 1.432 % Nb2O5 and 7.54 % P2O5 in the Discovery

Pit #1.

During June and July 2015, MDN Inc. completed a detailed prospecting geological survey on the Good

Hope Property with the objective of finding larger zones of mineralized, non-radioactive carbonatite

focussing on Site #28 and Site #21. Seven sites were trenched (Trenches 1 to 7) and from these trenches 64

channel samples were cut. The first trench, TR-01-PL-15, revealed a non-radioactive carbonatite at the

contact with a syenite. The carbonatite is at least 5 meters wide by 15 meters long, and observations indicate

that it extends underneath the swamp for an unknown distance. The best result from 26 channel samples in

trench TR-01-PL-15 is 1.205% Nb2O5 over 1.10 meters.

A Heliborne magnetic and radiometric survey (400 x 800 m) was flown on Aug. 3, 2016 by Prospectair on

behalf of Rudy Wahl on claim 4256251. A gamma-ray total counts anomaly occurs on the center of the

claim. Two drill holes were completed in September 2016 for a total of 280.7 m on an airborne radiometric

anomaly near Site #28, claim 4256251. The assay highlights for drill hole PL-01 include 0.45 % Nb2O5

over 1.0 m and 6.25 % P2O5 over 1.0 m. The assay highlights for drill hole PL-02 include 0.34 % Nb2O5

over 1.0 m and 5.81 % P2O5 over 1.0 m. The Niobium mineralization in drill core is associated with

carbonatite.

The First Nation community in close proximity to the Good Hope Property is an Ojibway Pic River First

Nation located on the northern shore of Lake Superior at the mouth of the Pic River, east of Marathon. On

the morning of June 7, 2017, Anthony Cohen, President and CEO of Plato, and Rudy Wahl, property owner,

met with members of the Pic River First Nations: Ms. Juanita Starr, Economic Development Manager and

her colleague Brittney to discuss the Good Hope Project. Mr. Cohen gave both Juanita and Brittney his

business card. The Pic River FN members said that they have eager workers who would be available for

employment opportunities when the time comes. Mr. Wahl and Mr. Cohen thanked them and told them that

they would keep them updated on the project as it progresses to the next exploration stages.

Plato Gold completed prospecting, mapping and sampling June 5 to 29, 2017 on the Good Hope Property.

A total of 55 carbonatite, ijolite and alkali granite samples were collected and submitted for assay on six

claims. The exploration team also described each outcrop/boulder that they reviewed which did not contain

carbonates (e.g., paragneiss, metasediment and alkali granite). A total of 201 outcrop stations were

described on seven claims.

The mapping program consisted of due diligence sampling of previously recognized high grade samples

and discovery of additional ijolite and carbonatite occurrences in four distinct areas on the Property. Plato’s

due diligence sampling at the Discovery Pit #1 found 1.055 %Nb2O5 and 9.25 % P2O5. Plato’s due diligence

grab sample from 2015 Trench TR-01-PL-15 found 1.053 % Nb2O5 and 6.73 % P2O5. The four areas of

mineralization identified during this mapping program are: Site #28 (claim 4256251), Site #21A (claim

4246269), Sites #22 and 25 (claim 4256252) and Site #37 (claim 4256259). Although these mineralized

sites were previously known, Plato’s exploration team increased the area of the mineralized sites and found

new mineralized outcrops within these sites. Site visits to the Property took place on June 5, 6 and 22, 2017.

Plato’s exploration team also found new outcrops of niobium mineralization. At Site #28, an outcrop of

syenite (or fenitized alkali granite) with ferro-carbonatite veins contains 393 ppm Nb in the ferro-

carbonatite and 186 ppm Nb in the syenite with carbonatite veins. The location of these anomalous Nb

samples can be used as an exploration pathfinder to find carbonatite intrusive bodies at Site #28. The

mapping program also discovered a 70 m long ijolite dyke within the alkali granite breccia and carbonatite

matrix at Site #28. This ijolite dyke connects trenches TR-04A-PL15 and TR-04B-PL15 ijolite with a new

outcrop of ijolite 70 m to the west.

The mapping program covered a 1.5 by 2.5 km area within Site #21A (claims 4246269, 4246255 and

4256253), the majority of which were not previously prospected or sampled. The highlights of the mapping

include: discovery of a 700 m long northeast trending alkali granite breccia with carbonatite matrix pointing


Plato Gold Corp


towards Prairie Lake. It is not known if the carbonatite continues under the lake. Also, discovery of a 1.8

km long northwest trending ijolite characterized by a magnetic high anomaly. Plato’s due diligence

sampling at Site #21A pit found 764 ppm Nb and 1.70 % P2O5 in calcio-carbonatite with 1% pyrochlore

and 257 ppm Nb and 0.41 % P2O5 in ferro-carbonatite with 1% pyrochlore. Plato’s new outcrops of

anomalous niobium values at Site #21A range from 112 to 349 ppm Nb.

The mapping program sampled ijolite and silico-carbonatite at Site #22 and 25 (Claim 4256252). The

mapping program discovered a 70 m northwest trending ijolite which corresponds to a magnetic high

anomaly. The ijolite is on a topographic high and the carbonatite is possibly in the adjacent topographic

low ground. Plato’s due diligence sampling of 2011 trench TR-PL-11-001 at Site #22 also confirms the

presence of anomalous niobium and phosphorus: Plato’s due diligence sampling of silicio-carbonatite found

287 ppm Nb and 1.64 % P2O5 and 130 ppm Nb and 5.69 % P2O5 in a ferro-carbonatite. Fenitized alkali

granite with carbonate + galena veinlets contained 224 ppm Nb.

Site #37 (Claim 4256259) contains similar alkali granite with carbonatite as Site #28. Plato’s due diligence

sampling of a silicio-carbonatite at Site #37 contains 657 ppm Nb and 2.36 % P2O5.

Julie Selway and Thomas Chudy relogged drill core for PL-01 at MNDM core library in Thunder Bay on

June 23 and 24, 2017. The drill core was not resampled and assayed, as the historic assays are sufficient to

indicate the presence of niobium mineralization on the Good Hope Property at this early stage of

exploration. Intervals with elevated levels of niobium mineralization were visually checked for pyrochlore

mineralization. Detailed due diligence relogging and photographing of drill hole PL-01 by Plato’s

exploration team showed an excellent correlation between the rock types found in the surface trench TR-

01-PL15 and drill core. The drill core shows several generations of carbonatite and patches rich in

pyrochlore mineralization. Multiple generations of apatite associated with the carbonatite and the niobium

mineralization were identified using ultraviolet light.

In conclusion, the prospecting and sampling of the Good Hope Niobium Property successfully confirmed

the historic sampling and identified new carbonatite and ijolite outcrops with anomalous Niobium and

Phosphorus. Re-logging of the previous drill hole PL-01 visually confirmed the presence of pyrochlore

associated with apatite in carbonatite veins.

Carbonatite is easily weathered and thus difficult to find in outcrop. The carbonatite is likely in the swamps

on the Property. It is preserved as the matrix within the alkali granite breccia and in contact with ijolite on

the Good Hope Property. The Qualified Person recommends a drill program to search for pyrochlore

mineralization hosted by carbonatite.


Plato Gold Corp


The QP recommends a 1200 m drill program consisting of 3 holes at 300 m each and 3 holes at 100 m each.

The drill holes should target under the swamps at Site #28 and 21A. The purpose of the 300 m long holes

is to drill deep enough to locate a large carbonatite body. Three holes will need to be drilled at each site in

order to model the orientation of the carbonatite body in 3D. Once the carbonatite body has been identified

the location of the drill holes can be adjusted to intersect it again.

4.4 Requirements to Retain the Property and Exploration Plan and Permit

In Ontario, to retain a mining claim, companies must submit an assessment file to MNDM’s Geoscience

Assessment Office showing that they have spent $400/per claim unit on exploration on each claim. One

claim unit is equal to 16 hectares. The initial mining claim is issued for a term of 2 years and then renewed

every year afterwards.

Plato has an Exploration Permit PR-17-11038 on the Good Hope Property dated March 21, 2017. The

Exploration Permit is effective for 3 years. The Exploration Permit covers all of the optioned Good Hope

claims except for 4246260, 4256256, 4256257 and 4261198. The four claims not covered by the

Exploration Permit are located on the east side of the Property where access is difficult. An Exploration

Permit application can be submitted at a later date for these claims if Plato decides to do drilling on them.

The Exploration Permit includes:

• Line cutting, where the width of the line is more than 1.5 metres.

• Mechanized drilling, where the weight of the drill is greater than 150 kg.

• Mechanized surface stripping (overburden removal), where the total combined surface area stripped is greater than 100 square metres and up to advanced exploration thresholds, within a 200-metre radius.

• Pitting and trenching (rock), where the total volume of rock is greater than 3 cubic metres and up to advanced exploration thresholds, within a 200-metre radius.

5.0 ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE, AND

PHYSIOGRAPHY

5.1 Access

The Good Hope Property is located 45 km northwest of Marathon and 190 km northeast of Thunder Bay

(Figure 4-1). The Property can be accessed by driving west of Marathon on Trans Canada Highway #17 for

about 33 km. Turn onto Deadhorse Creek Road at UTM Z16, E 523250 m, N 5407231 m, NAD 83. The

Deadhorse Creek Road passes through the west side of the Property. Drive along Deadhorse Creek Road

past Prairie River at 24 km, UTM Z16, E 521210 m, N 5427324 m (Figure 5-1). Turn onto the trail to Site

#28 near 29 km at UTM Z16, E 519363 m, N 5431721 m. Park the truck and walk along the trail. Trench

TR-01-PL15 is located at UTM Z16, E 519599 m, N 5432544 m and Discovery site Pit #1 is located at

UTM Z16, 519637 m, N 5432636 m.

Figure 5-1 Prairie River next to Deadhorse Creek Road

The closest major airport to the Property is in Thunder Bay about 300 km west of Marathon (Figure 4-1).

Marathon has a small airport just west of town, but it is only used by helicopters, forest fire fighters and

private planes. The Canadian Pacific Railway is located along the Trans-Canada Highway #17 and passes

the northern part of the town of Marathon. Thunder Bay is a regional hub with highways and railways east

to Toronto, west to Winnipeg and south to the United States. Thunder Bay is also a major shipping port on

Lake Superior.

5.2 Climate and Vegetation

The daily average temperature ranges from -15 ºC in January to 16 ºC in July

(http://www.farmzone.com/statistics/CL6048231/no027). The highest average accumulation of rain for the

month is 111 mm in October and 109 mm in June. The highest accumulation of snow for a month is 92 mm

in January.

Drilling can be conducted year round except for spring thaw in mid-March and April when it is too muddy

in the bush. Geological mapping and outcrop sampling can be conducted May to November when there is

no snow on the ground.


Plato Gold Corp


The vegetation consists of aspen, birch and spruce on most of the Property and thick alders and underbrush

in the low lying areas (MNDM assessment report: 2.50419). The property is forested with spruce and cedar

(MNDM assessment report: 2.56230).

Neys Provincial Park is located 30 km west of Marathon and hosts the Coldwell alkaline Complex

(https://en.wikipedia.org/wiki/Neys_Provincial_Park). Neys is within the Central Boreal Forest Region of

Ontario. As such it is home to a predominantly coniferous forest, however some boreal deciduous species

can be found near waterways and former beaver dams (e.g., white birch, black spruce). Some of the most

common plant species include the Bunchberry, Labrador Tea, blueberry, bearberry, larch, mountain maple,

a wide variety of fungi. These plants are an attraction to such forest species as the Woodland Caribou,

Moose, and the Black Bear. Black bears were seen on the Deadhorse Creek Road on an almost daily basis

during the mapping program (Figure 5-2).

Figure 5-2 Black bear on the left side of Deadhorse Creek Road.

5.3 Physiography

The region consists mainly of low terrain, including swamps separated by hills that rise 100-200 m above

the swamps (MNDM assessment file: 2.50419).


Plato Gold Corp


5.4 Infrastructure and Local Resources

The population of the town of Marathon is 3,273 people in 2016

(https://en.wikipedia.org/wiki/Marathon,_Ontario). The motto of the town of Marathon is “Built on Paper,

Laced with Gold”. The town was named after Marathon Pulp Inc, which operated a pulp mill 1946-2009.

The Hemlo gold camp was discovered in the early 1980’s east of Marathon. There are three gold mines in

the Hemlo camp: Golden Giant and David Bell mines owned by Barrick Gold Corporation and Williams

mine is jointly owned by Teck Cominco and Barrick Gold Corporation. Marathon has skilled labour for

mining operations. Marathon also has hotels, restaurants, hardware stores and a hospital.

Aguasabon Generating Station is a hydroelectric power station on the Aguasabon River near Terrace Bay

(http://www.opg.com/generating-power/hydro/northwest-ontario/Pages/aguasabon-station.aspx). Terrace

Bay is located 70 km from the Property (Figure 4-1). Pine Portage Generating Station is a hydroelectric

power station on the Nipigon River located 39 km north of the town of Nipigon

(http://www.opg.com/generating-power/hydro/northwest-ontario/Pages/pine-portage-station.aspx). Pine

Portage is the largest hydro power plant along the Nipigon River. The other two hydroelectric power

stations north of Nipigon are Cameron Falls and Alexander. Nipigon is located 186 km west of Marathon.

Sources of water on the Property include Prairie Lake, Ruffle Lake, Prairie River and numerous swamps.

The Property’s surface rights are owned by the crown and they are sufficient for future mining operations.

Plato’s Good Hope project is in the exploration stage and does not yet have 43-101 compliant

resource/reserve or a prefeasibility study; therefore, discussion on potential tailings storage areas, potential

waste disposal areas, heap pad leach pad areas and potential processing tailings storage area for mining

operations is not relevant.

6.0 HISTORY

6.1 2010, Rudy Wahl

The discovery of Niobium mineralization at Good Hope was made by Rudy Wahl in 2010 when he

identified 1.63 % Nb2O5 in a small outcrop on Site #28 (Figure 6-1 and Figure 6-2) (MNDM assessment

report 2.56230).

6.1 2011, Canadian International Minerals Inc.

Canadian International Minerals completed prospecting, rock sampling, radiometric surveys, soil sampling,

trenching and channel sampling in May to July 2011 (MNDM assessment file: 2.50419). Canadian

International optioned the property from Rudy Wahl. The focus of the exploration was the search for rare-

earth elements (“REE’s”).

Rock sample WJH-11-014 from claim 4256259 was analyzed using x-ray diffraction and the following

minerals were identified: garnet, microcline, dolomite, albite, quartz and a possible perovskite.

Canadian International walked along grid lines carrying a hand held gamma ray spectrometer May to July

2011 on claims 4256251, 425652, 4256259 and 4256258 and additional areas to the west. A total of 56 rock

samples were collected from outcrops, of which 48 were submitted for assay. Four soil samples were also

collected and sent for assay.

Canadian International dug 12 trenches (TR-11-PL-001 to TR-11-PL-012) on radiometric highs on the

Property between June and July 2011. A total of 238 channel samples were collected from the trenches and

sent for assay. Ten trenches were located along Deadhorse Creek Road on claim 4256252 (Figure 6-3).

Two trenches were located on claim 4256251, at Site #28 (Figure 6-4).

Figure 6-4 Map of Canadian International’s trenches 10 and 11 on claim block 4256251 (MNDM assessment file: 2.50419).

The conclusions of the radiometric work were that REE’s can be associated with areas of anomalous

radioactivity, both high and low radiometric anomalies can be indicative of REE enrichment and Th in

particular is a useful vector to determine areas that may be anomalous in REE.

6.2 2014, Rudy Wahl

In recognition of this Niobium discovery, Rudy Wahl received the Bernie Schnieders Discovery of the Year

Award for 2014 from the Northwestern Ontario Prospectors’ Association (NWOPA).

In September to December 2014, Dr. Wahl followed up on his discovery with prospecting, hand stripping,

geological mapping and rock sampling in 5 pits that he dug within Site #28 on claim 4256251 (Figure 6-5)


Plato Gold Corp


(MNDM assessment report: 2.56230). A total of 17 samples were assayed for Nb2O5 % and P2O5 % with

up to 1.432 % Nb2O5 and 7.54 % P2O5 in the Discovery Pit #1 (Table 6-1).

Figure 6-5 Location of pits dug in 2014 by Rudy Wahl on claim 4256251 (MNDM assessment report: 2.56230).

Table 6-1 Rudy Wahl’s assays for 2014 pits (MNDM assessment report: 2.56230).

6.3 2014, Roger Mitchell

Mineralogical studies completed in October 2014 by Professor Roger H. Mitchell on samples from Pit #1

at Site #28 (MNDM assessment report: 2.56230).

Dr. Mitchell key pints are:

Identification of two main types of pyrochlore:

1. Pcl-1- a F-free, Sr-poor type with relatively high Fe and Nb

2. Pcl-2 – a F-Na-Sr-bearing type with relatively low Fe and Nb

There is also a Nb-rich pyrochlore with about 80 wt% Nb2O5.

All pyrochlores are ThO2 free with very low UO3. This is important as Th and U contents go into the slag

and hence radionuclide problems are low for these pyrochlores.

Many of the pyrochlores occur as aggregates in clast-like masses of prismatic apatite. The pyrochlores are

large (up to 1 mm), so separation from apatite and carbonates should be easy.


Plato Gold Corp


Carbonatite contains pyrochlores, calcite, ferroan dolomite, calcio-siderite, barite, ancylite, synchysite-Ce,

iron oxides/hydroxides, quartz K-feldspar, pyrite and fluorite. It is important that there is only one niobium-

bearing phase unlike at other localities where the pyrochlore is replaced by ferrocolumbite.

Mineralogical Studies in December 2014 by Professor Roger Mitchell on samples from Pit #3 at Site #28

(MNDM assessment report: 2.56230) found that the pyrochlores in Pit #3 are exactly like those in Pit #1

with low Th and U and high Nb.

Mineralogical Studies on TR-01-PL-15 found a cluster of pyrochlores within prismatic apatite cumulates

(Figure 6-6).

6.4 2015, MDN Inc.

In February 2015, Rudy Wahl optioned the Good Hope Niobium Property to MDN Inc of Montreal.

During June and July 2015, MDN Inc. completed a detailed prospecting geological survey on the Good

Hope Property with the objective of finding larger zones of mineralized, non-radioactive carbonatite

focussing on Site #28 and Site #21 (MNDM assessment report 2.56640). The exploration work consisted

of prospecting, rock sampling, spectrometer radiometric surveys, trenching and channel sampling. A total

of 102 grab samples and 64 channel samples were collected and assayed. The best grab sample assays are

from resampling of the Discovery Pit #1 at Site #28 and from trench TR-01-PL-15 (Table 6-2).

Table 6-2 MDN Inc.’s anomalous grab samples with > 0.1 % Nb2O5 (MNDM assessment report 2.56640) All of the samples are from claim 4256251, except for sample 1393709 which is from claim 4246269.

Seven sites were trenched (Trenches 1 to 7) and from these trenches 64 channel samples were cut (Figure

6-7). The site selected for TR-02-PL-15 was covered by too much overburden and was backfilled. The site

selected for TR-07-PL-15 was not of significant interest and was backfilled.


Plato Gold Corp


Figure 6-7 MDN Inc.’s trench location map, claim 4256251 (MNDM assessment report 2.56640)

The first trench, TR-01-PL-15, revealed a non-radioactive carbonatite at the contact with a syenite. The

carbonatite is at least 5 meters wide by 15 meters long, and observations indicate that it extends underneath

the swamp for an unknown distance. The best result from 26 channel samples in trench TR-01-PL-15 is

1.205% Nb2O5 over 1.10 meters.


Plato Gold Corp


Figure 6-8 MDN Inc.’s channel samples for trench TR-01-PL-15, claim 4256251 (MNDM assessment report 2.56640).

Trench TR-04-PL-15 revealed a contact between ijolite breccia and syenite breccia, both matrix being

carbonatite, with a chunk of massive carbonatite (Figure 6-9). Again, the carbonatite most likely extends

underneath the swamp. The best channel sampling result for TR-04 is 0.437% Nb2O5 over 0.60 meters. In

the same trench, three non-adjacent channel samples had 0.180 % Nb2O5 over 1.0 m, 0.437 % Nb2O5 over

0.6 m and 0.254 % Nb2O5 over 1.0 m in syenite breccia with carbonatite matrix.


Plato Gold Corp


Figure 6-9 MDN Inc.’s channel samples for trench TR-04A-PL-15, claim 4256251 (MNDM assessment report 2.56640).

A mineralogical study was conducted at the University of Quebec in Montreal with a scanning electron

microprobe on samples from trench TR-01-PL-15 found the pyrochlore is U-poor in ferro-carbonatite. The

pyrochlore contains fluoro-carbonates (likely synchsite) and other related minerals. The pyrochlore crystals

occur associated with apatite. Calcite is major component in the ferro-carbonatite facies.

MDN Inc.’s summary was that the 2015 exploration program was successful in discovering a new type of

niobium mineralization which is potentially a non-radioactive carbonatite intrusion. As the discovery

coincides with a low magnetic/low topography sector, all the multi square-kilometers low topography, low

magnetics area covered by the Good Hope Property, is considered highly prospective.

7.0 GEOLOGICAL SETTING AND MINERALIZATION

7.1 Regional Geology

The Good Hope Property is located within the Wawa Subprovince of the Superior Province. The Wawa

Subprovince is composed of two linear greenstone belts which are separated by granitoid plutonic rocks

(Williams et al., 1991). The greenstone belts are composed of metamorphosed komatiite, basalt, dacite and

rhyolite and associated metasedimentary rocks.

Midcontinent Rift represents an aborted or failed rift resulting from an upwelling mantle plume during

Mesoproterozoic time at ~1.1 Ga (Burke & Dewey, 1973) (Figure 7-1). The rift is characterized by a large

volume of igneous material which includes the tholeiitic volcanic rocks and related rhyolite and granophyre

of the Keweenawan Supergroup, mafic-ultramafic sills and intrusions of the Duluth Complex and alkaline

and carbonatite intrusions of Ontario (Wu et al, 2016).


Plato Gold Corp


Figure 7-1 Distribution of alkaline rocks and carbonatite complexes within the Canadian part of the Midcontinent Rift (from Wu et al., 2016).

Within the Superior Province, numerous alkaline and carbonatitic rocks are distributed along the Trans-

Superior Tectonic Zone (Wu et al., 2016). Four alkaline rock carbonatite complexes have been identified

along this Zone: Coldwell, Chipman, Killala Lake and Prairie Lake (Figure 7-1). The Coldwell Complex is

one of the largest alkaline complexes in the world with an area of ~490 km2 and is composed of subalkaline

and alkaline gabbro, ferroaugite syenite, diverse contaminated syenites, ferroaugite syenite and A-type

quartz syenites (Mitchell et al., 1993). The Killala complex consists of troctolite, gabbro, monzonite,

syenite, nepheline monzonite-syenite and mafic-syenite dykes (Wu et al., 2016). Both the Coldwell

Complex and the Killala Lake complex do not contain carbonatites, whereas Chipman Lake and Prairie

Lake complexes do contain carbonatites.

7.2 Local Geology – Prairie Lake Complex

The Good Hope Property claims surrounds the Prairie Lake Complex (Figure 9-1). The center of the Prairie

Lake Complex is not included in the Good Hope Property. The Prairie Lake Complex is circular with an

approximate surface area of 8.8 km2 and is topographically located on a circular hill surrounded by low

lying marshy ground (Cleaver, 2017). The Prairie Lake Complex corresponds to an aeromagnetic high

anomaly (Sage, 1987).

The Prairie Lake Complex consists of an ijolite core enclosed by an outer rim of mixed carbonatite,

siliciocarbonatite and calcite ijolite (Sage, 1987). The rock units of the Prairie Lake Complex in

approximate order of intrusion are (Wu et al., 2016):

1. Biotite pyroxenite and calcite carbonatite (I) – Carbonatite (I) consists of very friable coarse rock consisting of large interlocking calcite crystals with rare apatite.

2. Ijolite series rocks – ijolite (pyroxene + nepheline), calcite mela-ijolite (silicocarbonatite or hollaite), mela-ijolite (pyroxene > nepheline with biotite and andradite-schorlomitic garnet) and wollastinite ijolite.

3. Potassic syenitic rocks – Na-poor potassium feldspar, nepheline and pyroxene

4. Heterogeneous carbonatite (II) – wide modal variations of calcite, apatite, mica, olivine and magnetite with accessory Na-Ca-pyrochlore, U-Ta-bearing pyrochlore, Pb-pyrochlore, niobian zirconolite, perovskite-latrappite-loparite solid solution, baddeleyite and pyrite.

5. Dolomitic carbonatite – found only in a small area at the northern margin. Lacks apatite and mica.

Prairie Lake Complex has been explored by Nuinsco Resources Limited in search of uranium, niobium,

tantalum and REE’s with apatite and wollastonite as by-products (Nuinsco website:

http://www.nuinsco.ca/projects/prairie-lake/).

7.3 Property Geology and Mineralization

The Good Hope Property consists of paragneiss and metasedimentary bedrock and alkali granite, ijolite and

carbonatite. The alkali granite shows variable degrees of fenitization and brecciation. Alkali granite breccia

has carbonatite veins/ matrix between the clasts. Three types of carbonatite are found on the property:

calciocarbonatite, ferrocarbonatite and silicocarbonatite.


Plato Gold Corp


The airborne EM apparent resistivity at 33840 Hz map suggests that the Prairie Lake Carbonatite Complex

proper is surrounded by a 1.0 to 1.5 km wide outer ring which includes most of the Good Hope Property

(Figure 7-2). The peripheral region of the main complex has the potential to host late stage carbonatite

dykes and veins similar to the carbonatite veins in the alkali granite breccia at Site #28.

The airborne magnetics high correlate with ijolite and magnetic low correlates with swamps and lakes

which are possible weathered carbonatites. The total counts radiometric high at Site #28 correlates with

elevated potassium in the alkali granite (Figure 6-10).

Figure 7-2 Good Hope apparent resistivity map at 33840 Hz (from OGS GDS 1104).

The Property hosts Niobium mineralization in pyrochlore (a Nb-oxide mineral). The Niobium

mineralization differs from that in Prairie Lake Complex in that it is low in Th and U contents (section 6.3).

Two paragentic varieties of carbonatites were identified on the basis of mineral abundances and textures:


Plato Gold Corp


pyrochlore-rich and pyrochlore-poor (Cleaver, 2017). The pyrochlore-poor phase represents a later stage of

crystallization (Cleaver, 2017). The pyrochlore-rich carbonatite contains early crystallized cumulates of

apatite and Na-Ca pyrochlore with interstitial carbonate minerals (Cleaver, 2017).

8.0 DEPOSIT TYPES

Carbonatites are defined in the IUGS system of classification as igneous rocks composed of more the 50

modal % of primary carbonate and less than 20% SiO2 (LeMaitre, 2002). Since carbonatites can be derived

from a variety of genetically distinct parental magmas, Mitchell (2005) devised a mineralogical-genetic

classification in which carbonatites are defined as any igneous rocks containing greater than arbitrary,

although practical, 30 vol.% primary igneous carbonate, regardless of silica content.

Many plutonic and hypabyssal carbonatites represent rocks formed in magma chambers underlying

volcanic complexes (Mitchell, 2015). For example, the Napak volcano, Uganda volcanic system consists

of two parts: a central complex of carbonatite and modally-diverse rocks of the ijolite suite and fenites; and

the remnants of a nephelinite volcanic cone. The central calcite carbonatite is concentrically and vertically

banded and forms a 400 m diameter plug from which dykes extend into the ijolite complex. The carbonatite-

ijolite complex is considered to represent a plutonic/hypabyssal rocks which crystallized from a nephelinitic

parental magma in the conduit of the volcano. Caldron subsidence can be expected to have occurred in the

formation of carbonatite-silicate rock complexes which now lack associated remnant volcanic cones.

Mitchell (2015) summarized the general characteristics of carbonatite complexes: the majority of

carbonatite – silicate rock complexes are circular to elliptical intrusions in planar cross section. Cone sheets

and ring dykes are common, Typically the sequence of intrusion is silicate rocks, calcite carbonatites,

dolomite carbonatites and ferrocarbonatites followed by carbohydrothermal veins. Several generations of

magmatism can occur leading to very complex cross cutting relationships. Megaxenoliths of silicate rocks

can be found within carbonatite units and vice versa. The complexes are commonly surrounded by a zone

of sodium metasomatism termed fenitization. Niobium mineralization can be associated with any of the

rocks occurring in the complexes, apart from the later stage ferrocarbonatites which have a better potential

for rare earth element deposits than niobium.

9.0 2017 EXPLORATION

9.1 Aboriginal Consultation


Nation located on the northern shore of Lake Superior at the mouth of the Pic River, east of Marathon

(Figure 4-1).

On the morning of June 7, 2017, Anthony Cohen, President and CEO of Plato, and Rudy Wahl, property

owner, met with members of the Pic River First Nations: Ms. Juanita Starr, Economic Development

Manager and her colleague Brittney to discuss the Good Hope Project. Mr. Cohen gave both Juanita and

Brittney his business card. The Pic River FN members said that they have eager workers who would be

available for employment opportunities when the time comes. Mr. Wahl and Mr. Cohen thanked them and

told them that they would keep them updated on the project as it progresses to the next exploration stages.

9.2 Prospecting, Mapping and Sampling

9.2.1 Personnel

The prospecting, mapping and sampling took place June 5 to 29, 2017 and was conducted by Carlos

Chamale, senior geologist for J-J Minerals, and Joseph Suk, junior geologist for Plato. Julie Selway,

Principal Geologist for J-J Minerals visited the Property with Mr. Chamale and Mr. Suk on June 5, 2017 to

review Property access and the geology at Site #28. Julie Selway, Carlos Chamale, Joseph Suk, Rudy Wahl

(Property owner), and Anthony Cohen (President and CEO of Plato) visited the Property on June 6, 2017

to review the geology at Site #28 and Site #21A focusing on outcrops previously identified by Mr. Wahl.

Julie Selway, Thomas Chudy, Ph.D. expert on carbonatites from University of British Columbia, Carlos

Chamale, Joseph Suk and Rudy Wahl visited the Property on June 22, 2017 to review the geology of Site

#28 and Site #21A including a visit outcrops previously identified by Mr. Wahl and outcrops identified by

Mr. Chamale during this mapping program.

9.2.2 Methodology

The prospecting focused on the west side of the Property as this side has easy access using the Deadhorse

Creek Road. Traverse maps of for the prospecting is given in Appendix 5. A review of the property data

was used to select exploration targets with the most chance of finding ijolite and carbonatite. The geology

map of the Prairie Lake Carbonatite Complex indicates that the complex mostly consists of ijolite and


Plato Gold Corp


carbonatite. Exploration targeting searched for ijolite which were magnetic highs and topographic highs in

hopes of finding the carbonatite in the swamps and lakes with magnetic lows next to the ijolite. The

sampling consisted of due diligence samples of previously identified high grade outcrops and exploration

targets identified during this program.

A review of Forestry Inventory satellite orthophotos indicates that the colour and texture of the vegetation

in the images reflects the lithology. For example, the trees on Site #28 have a bluish hue similar to those at

Site #21A. The satellite images were used to distinguish between lithology units, but the ground truthing

was required to identify what each lithology unit was.

The mapping team walked along the flight path lines of the airborne mag and EM geophysics survey and

airborne radiometrics survey to make a direct comparison between the lithology with the geophysics

signature. This helped the team to correlate the total counts radiometric anomaly at Site #28 with the

abundance of alkali granite. The mapping team also walked along the boundary of a magnetic high and low

anomalies in search of ijolite with patches of carbonatite that have not yet been weathered. Since the rocks

were covered with thick moss, a scintillometer was used to locate radioactive rocks covered by moss or

overburden. Elevated scintillometer readings often corresponded with the presence of fine-grained

pyrochlore (Nb-mineral). HCl acid was used to confirm the presence of carbonate minerals in the field.

The field data was imported into the Arc several times a week and exploration targets were adjusted as the

correlation between the geophysics signature and the lithology was figured out and more lithological data

was collected. Rough lithology boundaries were plotted in the Arc.

The exploration team recorded the sample number, UTM coordinates, rock type and sample description for

each of the samples submitted for assay. Samples submitted for assay included carbonatite, ijolite, alkali

granite with carbonatite veining and any rocks with carbonate mineralization. A representative fresh sample

was chipped off the outcrop to put into the sample bag. Digital photos were taken of the outcrop from which

the sample came from and close up of the actual sample. The photo files were named with the sample

number. A sample tag was put in the bag with the sample and the bag was sealed with flagging tape. At the

end of the mapping program, the samples to be assayed were cut so that a slice was kept for future reference

and mineralogical studies. A total of 55 samples were collected and submitted for assay (Table 9-1). A

description of these samples is given in Appendix 2 and plotted in Figure 9-7 and Figure 9-9.

9.2.3 Results


and discovery of additional ijolite and carbonatite occurrences in four distinct areas on the Property (Figure

9-1). Discovery of new ijolite and carbonatite occurrences is significant because niobium mineralization in

the Prairie Lake complex occurs in both ijolite and carbonatite, although carbonatites are the dominate host

of the niobium mineralization. The Good Hope Property claims surround the Prairie Lake complex. The


Plato Gold Corp


observation that ijolite and carbonatite occurs in several areas throughout the Property increases the

exploration potential for niobium mineralization throughout the Property. Plato’s exploration team

successfully predicted the location of the ijolite occurrences on the basis of the high magnetic anomalies

and topographic highs. Plato’s exploration team used the ijolite locations as a pathfinder to find additional

carbonatite occurrences. The carbonatite is easily weathered and possibly occurs in the swamps and lakes

near ijolite occurrences.

Plato’s due diligence sampling confirmed outcrops with anomalous Niobium (Nb) and Phosphorus (P)

values and the summer mapping program identified new areas of anomalous Nb and P. Plato’s due diligence

sampling at the Discovery Pit #1 found 1.055 %Nb2O5 and 9.25 % P2O5. Plato will use the location of the

anomalous Nb samples, magnetic lows and topographic lows (e.g. swamps and lakes) to aid in drill targeting

for carbonatite for the fall drill program.

The four areas of mineralization identified during this mapping program are: Site #28 (claim 4256251), Site

#21A (claim 4246269), sites #22 and 25 (claim 4256252) and Site #37 (claim 4256259) (Figure 9-1 and

Appendix 4). Although these mineralized sites were previously known, Plato’s exploration team increased

the area of the mineralized sites and found new mineralized outcrops within these sites.

Figure 9-1 Good Hope Niobium Property geology map and 2017 sample locations.

An examination of the geology and mineralogy of the outcrops on the Good Hope Niobium Property helped

Plato’s exploration team better understand the mineralized system. It was noted that high-grade Nb

mineralization (>1.0 wt.% Nb2O5) occurs predominantly within carbonatite veins that contain apatite and

highly concentrated pyrochlore (i.e., main Nb-carrier). Mineralogical studies by Dr. Roger Mitchell and

Amy Cleaver concluded that there are two types of carbonatite at Good Hope: pyrochlore-rich and

pyrochlore-poor (Rudy Wahl website:

http://users.renegadeisp.com/~rwahl/Prairie%20Lake%20Rare%20Earth%20Property.htm). Ms. Cleaver’s

thesis concluded that the pyrochlore-rich carbonatite contains early crystallized cumulates of apatite and

Na-Ca pyrochlore with interstitial carbonate minerals (Figure 6-6) (Cleaver, 2017). The distribution of the

apatite cumulates within the carbonatite veins is heterogeneous and prone to cause a nugget effect during

sampling. The mineralized carbonatite veins are accompanied by a suite of smaller carbonatite veins that

have variable compositions ranging from Fe-Mg-rich to Si-rich varieties with variable Nb concentrations.

Plato’s exploration team is using this information together with geophysical and geological data to


Plato Gold Corp


ultimately find the source of the mineralized carbonatite veins. The results from the sampling program at

four sites are encouraging as they indicate the presence of a mineralized carbonatite system.

9.2.4 Site #28 (Claim 4256251, northwestern part of property)

The prospecting and geological mapping examined the lithology of outcrops (Figure 9-2). The grab samples

colour coded by Nb (ppm) and the described outcrops are plotted in Figure 9-7 and Figure 9-8. This claim

consists of alkali granite breccia with a carbonatite matrix and minor ijolite. The alkali granite shows

variable degrees of brecciation and fenitization (alteration to Na-amphibole and biotite) in drill core PL-01.

Figure 9-2 Good Hope Property, Site #28, historic and 2017 sampling map with satellite image background, claim 4256251.

The high ground on Site #28 corresponds to an airborne radiometric total counts high anomaly related to

the potassium content of the alkali granite breccia. To the north of the high ground is a swamp which

corresponds to a magnetic low and possibly the location of the carbonatite.

Plato’s due diligence sampling the Discovery Pit #1 and Trench TR-01-PL-15 confirms the presence of

high grade niobium and phosphorus mineralization.

Discovery Pit #1

Plato’s due diligence sampling at the Discovery Pit #1 found 1.055 % Nb2O5 and 9.25 % P2O5 (sample

1077352, Figure 9-3). Plato’s pit sample contains Fe-rich calcio-carbonatite with common calcite, ankerite,

apatite and 2% pyrochlore. This pit was originally sampled by Rudy Wahl in 2014 and was subsequently

sampled by MNDM Resident Geologists in 2014 and MDN Inc. in 2015 (Puumala et al., 2015, OFR 6303

and MNDM Assessment Report 2.56640). All of the assay results are similar for Nb (Table 9-3).

The mapping program discovered a 70 m long ijolite dyke within the alkali granite breccia and carbonatite

9.2.5 Site #21A (Claims 4246269, 4246255 and 4256253, southwestern part of

Property)

The mapping program covered a 1.5 by 2.5 km area within these claims, the majority of which were not

previously prospected or sampled. The grab samples colour coded by Nb (ppm) and the described outcrops

are plotted in Figure 9-9 and Figure 9-10. The highlights of the mapping include (Figure 9-6):

• Discovery of a 700 m long northeast trending alkali granite breccia with carbonatite matrix pointing towards Prairie Lake. It is not known if the carbonatite continues under the lake.

• Discovery of a 1.8 km long northwest trending ijolite characterized by a magnetic high anomaly. This ijolite trend has an exploration potential to host niobium mineralization as ijolite hosts niobium mineralization in Prairie Lake complex.

Plato’s due diligence sampling of the Site #21A pit confirmed the presence of anomalous niobium and

phosphorus mineralization:

• Plato’s due diligence sampling at Site #21A pit found 764 ppm Nb and 1.70 % P2O5 in calcio-carbonatite with 1% pyrochlore and 257 ppm Nb and 0.41 % P2O5 in ferro-carbonatite with 1% pyrochlore (Table 9-6).

• Plato’s samples were taken from the same pit as MDN Inc.’s 2015 sample with 340 ppm Nb and Rudy Wahl’s sample with 0.906 % Nb2O5 and 9.89 % P2O5 (MNDM assessment report 2.56640).

Plato’s due diligence sampling of dark red fenitized alkali granite (sample 1077390) with interstitial

carbonate contains anomalous 554 ppm Nb (Table 9-6). In 2015, MDN Inc.’s collected 5 samples from the

same outcrop with assays of 258, 351, 424, 458 and 740 ppm Nb (MNDM assessment report 2.56640). This

outcrop is similar to the fenitized alkali granite with carbonatite veins at Site #28 and could be used as an

exploration pathfinder to carbonatite intrusive bodies at Site #21A.

Plato’s sampling of ijolite with patches of carbonatite shows that anomalous niobium contents can occur in

both rock types. Plato’s assay of dark grey to black mela-ijolite (sample 1077386) contains 114 ppm Nb

and the patches of calcio-carbonatite within it (sample 1077389) contains 145 ppm Nb. This occurrence is

a topographic high of dominantly ijolite with a swamp next to it. Similar to Site #28, the main carbonatite

occurrence could be located in the swamp. This is a future exploration target for carbonatite.

Plato’s new outcrops of anomalous niobium values range from 112 to 349 ppm Nb (Table 9-6). The location

of these anomalous samples can be used as an exploration pathfinder to find carbonatite intrusive bodies at

Site #21A.

9.2.6 Site #22 and 25 (Claim 4256252, south of Deadhorse Creek Road)

The mapping program sampled ijolite and silico-carbonatite in this claim. The grab samples colour coded

by Nb (ppm) and the described outcrops are plotted in Figure 9-7 and Figure 9-8. The mapping program

discovered a 70 m northwest trending ijolite which corresponds to a magnetic high anomaly. The ijolite is

on a topographic high and the carbonatite is possibly in the adjacent topographic low ground.

Plato’s due diligence sampling of 2011 trench TR-PL-11-001 at Site #22 also confirms the presence of

anomalous niobium and phosphorus:

• Plato’s due diligence sampling of silicio-carbonatite found 287 ppm Nb and 1.64 % P2O5 and 130 ppm Nb and 5.69 % P2O5 in a ferro-carbonatite. Fenitized alkali granite with carbonate + galena veinlets contained 224 ppm Nb (Table 9-7).

• Canadian International assayed 19 grab samples in 2011 from the same trench with a range of 3 to

496 ppm Nb and an average of 172 ppm Nb (MNDM assessment report 2.50419).

9.2.7 Site #37 (Claim 4256259, west of Site #28)

This claim contains similar alkali granite with carbonatite as Site #28. The grab samples colour coded by

Nb (ppm) and the described outcrops are plotted in Figure 9-7 and Figure 9-8. Plato’s due diligence

sampling of the Site #37 confirms the presence of anomalous niobium and phosphorus: Plato’s due

diligence sampling of a silicio-carbonatite at Site #37 contains 657 ppm Nb and 2.36 % P2O5 (Table 9-7).

MDN Inc.’s 2015 sample from the same outcrop contains 597 ppm Nb, and Rudy Wahl’s sample contains

0.157 % Nb2O5 (1097 ppm Nb) Nb2O5 and 1.50 % P2O5 (MNDM assessment report 2.56640).

9.3 Relogging of Drill Hole PL-01

Julie Selway and Thomas Chudy relogged drill core for PL-01 at MNDM core library in Thunder Bay on

June 23 and 24, 2017 (Appendix 6). Historic drill hole PL-01 was centered on a radiometric anomaly on

Site #28, claim 4256251 is described in section 6.5. The drill core was not resampled and assayed, as the

historic assays are sufficient to indicate the presence of niobium mineralization on the Good Hope Property

at this early stage of exploration. Intervals with elevated levels of niobium mineralization were visually

checked for pyrochlore mineralization.

Detailed due diligence relogging and photographing of drill hole PL-01 by Plato’s exploration team showed

an excellent correlation between the rock types found in the surface trench TR-01-PL15 and drill core

(Figure 9-2). The relogging helped the team better understand the niobium mineralization. The drill core

shows several generations of carbonatite and patches rich in pyrochlore mineralization. Drill hole PL-01

contains up to 0.450 % Nb2O5 and 1.85 % P2O5 over 1 m in carbonatite. Multiple generations of apatite

associated with the carbonatite and the niobium mineralization were identified using ultraviolet light.

The dominant lithology in this drill hole was alkali granite with variable amounts of fenitization and

carbonatite veins. The alkali granite is fine to medium-grained and characterized by the abundance of

orange to red K-feldspar and quartz (Figure 9-11).

The breccia zone consists of clasts of alkali granite which has been fenitized (rimmed by black mixture of

blue-green amphiboles and biotite) with a carbonatite matrix interstitial to the clasts (Figure 9-11).

Three types of carbonatite was noted in the drill core (Figure 9-12):

1. Fine-grained, pinkish-grey Fe-rich carbonatite

2. Fine-grained, grey calcite carbonatite with lots of fizz reaction with HCl

3. Silicocarbonatite with fine-grained “salt and pepper” texture, melanocratic, 30-40% mafics and 60-70% carbonates

The distribution of the pyrochlore in the carbonatites is heterogeneous and in some intervals is abundant

(Figure 9-13). The apatite has several different habits: platy/scaly and fine-grained hairs which are white

under the ultraviolet light.

10.0 DRILLING

Plato has not completed any drilling on the Property, but Plato did relog the historic drill hole PL-01 from

Site #28, claim 4256251 (section 9.3).

11.0 SAMPLE PREPARATION, ANALYSES AND SECURITY

11.1 Sample Security

Samples for assay were collected by Carlos Chamale, senior geologist for J-J Minerals and Fladgate

Exploration Consulting Corporation’s (“Fladgate”). Sample bags were tied with flagging tape and placed

in rice bags. The rice bags were stored in Fladgate’s warehouse in Thunder Bay and then representative


Plato Gold Corp


slices were cut from each sample for future mineralogical studies by Fladgate. Fladgate delivered the

samples to Actlabs preparation lab in Thunder Bay.

11.2 Sample Preparation

External standards, blanks and field duplicates were not inserted into the sample stream because the purpose

of the sampling program was regional prospecting over multiple claims to identify the location of the

mineralization. These grab samples will not be used in a future resource estimate. Actlabs will insert internal

standards, blanks, pulp duplicates and preparation duplicates and these will be used to monitor the accuracy

and precision of the assays.

Actlabs’ Quality System is accredited to international quality standards through the International

Organization for Standardization /International Electrotechnical Commission (ISO/IEC) 17025 (ISO/IEC

17025 includes ISO 9001 and ISO 9002 specifications) with CAN-P-1578 (Forensics), CAN-P-1579

(Mineral Analysis) and CAN-P-1585 (Environmental) for specific registered tests by the Standards Council

of Canada (“SCC”). The accreditation program includes ongoing audits which verify the QA system and

all applicable registered test methods. ISO 17025 is the main standard used by testing and calibration

laboratories. Actlabs’ analytical lab in Ancaster has ISO 17025 certification.

11.3 Sample Analyses

The samples were prepared using analytical code RX1 which is a dry crush of the entire sample to 90% -

10 mesh followed by a riffle split and pulverization of a 250 g sample to 95% -200 mesh.

The samples were then assayed using analytical code 4Litho which uses lithium tetraborate fusion digestion

followed by analysis by Inductively Coupled Plasma (“ICP”) and Inductively Coupled Plasma Mass

Spectrometry (“ICPMS”). Elements analyzed include major oxides, trace elements and rare earth elements.

Fusion digests the entire sample and is the best method to analyze major oxides, refractory minerals and

REE minerals.

High grade Nb samples are also analyzed by analytical code Nb-XRF Assay which Nb2O5 is analyzed in

a fusion glass disc by X-ray Fluorescence (“XRF”).

A total of 55 grab samples were collected and submitted for assay from six claims (Table 9-1, Appendices

2 and 7). No QC samples were inserted in the sample stream as the purpose of the assays was regional

prospecting for Niobium mineralization. Reliance on Actlabs’ internal blanks, standards and duplicates to

monitor QA/QC is sufficient for this purpose.


Plato Gold Corp


Actlabs inserted internal standards, blanks, pulp duplicates and preparation duplicates within each sample

batch as part of their own internal monitoring of quality control. The Nb high-grade standards analyzed by

FUS-XRF were SX18-04 with a certified value of 1.32 % Nb2O5, SX18-05 with a certified value of 0.973

% Nb2O5 and SARM 3 with a certified value of 0.143 % Nb2O5. The Nb low grade standards analyzed by

FUS-MS were SARDM 3 with a certified value of 978 ppm Nb, JR-1 with a certified value of 15.2 ppm

Nb and W-2a with a certified value of 7.9. One method internal blank was inserted in the sample stream.

All of the internal standards and blank passed. Three pulp duplicates and one preparation duplicate were

analyzed and they all passed.

In the QP’s opinion the sample preparation, security and analytical procedure is adequate and to industry

standard for the purpose of due diligence of previous assayed samples and regional prospecting.

12.0 DATA VERIFICATION

12.1 Quality Control

All of Actlabs internal standards, blanks and duplicates passed. In the QP’s opinion, the assay data is

adequate for the purpose of the due diligence sampling and regional prospecting.

13.0 INTERPRETATION AND CONCLUSIONS


Highway 17. The Good Hope Property consists of paragneiss and metasedimentary bedrock and alkali

granite, ijolite and carbonatite. The alkali granite shows variable degrees of fenitization and brecciation.

Alkali granite breccia has carbonatite veins/ matrix between the clasts. Three types of carbonatite are found

on the property: calciocarbonatite, ferrocarbonatite and silicocarbonatite.

The Property hosts Niobium mineralization in pyrochlore. The Niobium mineralization differs from that in

Prairie Lake Complex in that it is low in Th and U contents. Two paragentic varieties of carbonatites were

identified on the basis of mineral abundances and textures: pyrochlore-rich and pyrochlore-poor. The

pyrochlore-poor phase represents a later stage of crystallization. The pyrochlore-rich carbonatite contains

early crystallized cumulates of apatite and Na-Ca pyrochlore with interstitial carbonate minerals.


Plato Gold Corp


Plato Gold’s June 2017 exploration program consisted of Aboriginal Consultation, prospecting, mapping

and sampling and relogging historic hole PL-01. The goal was to complete due diligence sampling on know

Niobium occurrences and to find new Niobium mineralization in carbonatite and ijolite.


Nation located on the northern shore of Lake Superior at the mouth of the Pic River, east of Marathon. On

the morning of June 7, 2017, Anthony Cohen, President and CEO of Plato, and Rudy Wahl, property owner,

met with members of the Pic River First Nations: Ms. Juanita Starr, Economic Development Manager and

her colleague Brittney to discuss the Good Hope Project.

Plato Gold completed prospecting, mapping and sampling June 5 to 29, 2017 on the Good Hope Property.

A total of 55 carbonatite, ijolite and alkali granite samples were collected and submitted for assay on six

claims. The exploration team also described each outcrop/boulder that they reviewed which did not contain

carbonates (e.g., paragneiss, metasediment and alkali granite). A total of 201 outcrop stations were

described.


and discovery of additional ijolite and carbonatite occurrences in four distinct areas on the Property. Plato’s

due diligence sampling at the Discovery Pit #1 found 1.055 %Nb2O5 and 9.25 % P2O5. Plato’s due diligence

grab sample from 2015 Trench TR-01-PL-15 found 1.053 % Nb2O5 and 6.73 % P2O5. The four areas of

mineralization identified during this mapping program are: Site #28 (claim 4256251), Site #21A (claim

4246269), sites #22 and 25 (claim 4256252) and Site #37 (claim 4256259). Although these mineralized

sites were previously known, Plato’s exploration team increased the area of the mineralized sites and found

new mineralized outcrops within these sites. Site visits to the Property took place on June 5, 6 and 22, 2017.

Plato’s exploration team also found new outcrops of niobium mineralization. At Site #28, an outcrop of

syenite (or fenitized alkali granite) with ferro-carbonatite veins contains 393 ppm Nb in the ferro-

carbonatite and 186 ppm Nb in the syenite with carbonatite veins. The location of these anomalous Nb

samples can be used as an exploration pathfinder to find carbonatite intrusive bodies at Site #28. The

mapping program also discovered a 70 m long ijolite dyke within the alkali granite breccia and carbonatite

matrix at Site #28. This ijolite dyke connects trenches TR-04A-PL15 and TR-04B-PL15 ijolite with a new

outcrop of ijolite 70 m to the west.

The mapping program covered a 1.5 by 2.5 km area within Site #21A (claims 4246269, 4246255 and

4256253), the majority of which were not previously prospected or sampled. The highlights of the mapping

include: discovery of a 700 m long northeast trending alkali granite breccia with carbonatite matrix pointing


Plato Gold Corp


towards Prairie Lake. It is not known if the carbonatite continues under the lake. Also, discovery of a 1.8

km long northwest trending ijolite characterized by a magnetic high anomaly. Plato’s due diligence

sampling at Site #21A pit found 764 ppm Nb and 1.70 % P2O5 in calcio-carbonatite with 1% pyrochlore

and 257 ppm Nb and 0.41 % P2O5 in ferro-carbonatite with 1% pyrochlore. Plato’s new outcrops of

anomalous niobium values at Site #21A range from 112 to 349 ppm Nb.

The mapping program sampled ijolite and silico-carbonatite at Site #22 and 25 (Claim 4256252). The

mapping program discovered a 70 m northwest trending ijolite which corresponds to a magnetic high

anomaly. The ijolite is on a topographic high and the carbonatite is possibly in the adjacent topographic

low ground. Plato’s due diligence sampling of 2011 trench TR-PL-11-001 at Site #22 also confirms the

presence of anomalous niobium and phosphorus: Plato’s due diligence sampling of silicio-carbonatite found

287 ppm Nb and 1.64 % P2O5 and 130 ppm Nb and 5.69 % P2O5 in a ferro-carbonatite. Fenitized alkali

granite with carbonate + galena veinlets contained 224 ppm Nb.

Site #37 (Claim 4256259) contains similar alkali granite with carbonatite as Site #28. Plato’s due diligence

sampling of a silicio-carbonatite at Site #37 contains 657 ppm Nb and 2.36 % P2O5.


behalf of Rudy Wahl on claim 4256251. A gamma-ray total counts anomaly occurs on the center of the

claim. Two drill holes were completed in September 2016 for a total of 280.7 m on an airborne radiometric

anomaly near Site #28, claim 4256251. The assay highlights for drill hole PL-01 include 0.45 % Nb2O5

over 1.0 m and 6.25 % P2O5 over 1.0 m. The assay highlights for drill hole PL-02 include 0.34 % Nb2O5

over 1.0 m and 5.81 % P2O5 over 1.0 m. The Niobium mineralization in drill core is associated with

carbonatite.

Julie Selway and Thomas Chudy relogged drill core for PL-01 from claim 4256251 at MNDM core library

in Thunder Bay on June 23 and 24, 2017. The drill core was not resampled and assayed, as the historic

assays are sufficient to indicate the presence of niobium mineralization on the Good Hope Property at this

early stage of exploration. Intervals with elevated levels of niobium mineralization were visually checked

for pyrochlore mineralization. Detailed due diligence relogging and photographing of drill hole PL-01 by

Plato’s exploration team showed an excellent correlation between the rock types found in the surface trench

TR-01-PL15 and drill core. The drill core shows several generations of carbonatite and patches rich in

pyrochlore mineralization. Multiple generations of apatite associated with the carbonatite and the niobium

mineralization were identified using ultraviolet light.


Plato Gold Corp


In conclusion, the prospecting and sampling of the Good Hope Niobium Property successfully confirmed

the historic sampling and identified new carbonatite and ijolite outcrops with anomalous Niobium and

Phosphorus. Re-logging of the previous drill hole PL-01 visually confirmed the presence of pyrochlore

associated with apatite in carbonatite veins. The areas of anomalous Niobium and Phosphorous can be used

as exploration pathfinders to find additional mineralization.

14.0 RECOMMENDATIONS

Carbonatite is easily weathered and thus difficult to find in outcrop. The carbonatite is likely in the swamps

on the Property. It is preserved as the matrix within the alkali granite breccia and in contact with ijolite on

the Good Hope Property. The Qualified Person recommends a drill program to search for pyrochlore

mineralization hosted by carbonatite.

The QP recommends a 1200 m drill program consisting of 3 holes at 300 m each and 3 holes at 100 m each.

The drill holes should target under the swamps at Sites #28 and 21A. The purpose of the 300 m long holes

is to drill deep enough to locate a large carbonatite body. Three holes will need to be drilled at each site in

order to model the orientation of the carbonatite body in 3D. Once the carbonatite body has been identified

the location of the drill holes can be adjusted to intersect it again. A budget for the drill program is given in

Table 14-1.
