SUMMARY

The Tahoe Lake property is located approximately 170 kilometers north northeast of the town of Red Lake, Ontario within NTS 53CI7. The property is wholly owned by Candor Ventures Inc. (Candor) and consists of three unpatented mineral claims totaling 768 hectares. The property is accessible by float/ski plane from the town of Red Lake. The winter road from Red Lake to North Spirit Lake is located approximately 15 kilometers to the west of the property.

The most recent government mapping is by Wood (1980 and 1988). Prior to Candor's acquisition of the property, the only documented exploration was in 1976-1977 by The Hanna Mining Company who conducted geological mapping, ground magnetic and Max-Min surveys and 512 meters of diamond drilling in six holes. In 2005, Candor completed an AeroTEM II helicopter-borne electromagnetic and magnetic survey of the property resulting in the identification of several high priority conductors.

The Tahoe Lake property is underlain by mafic to intermediate volcanics and pyroclastics, intermediate to felsic volcanics and pyroclastics, clastic metasediments and chemical metasediments. There is evidence to suggest that the volcanics are hydrothermally altered. Mineralization consists of pyrrhotite and pyrite occurring together as massive seams, stringers and disseminations in both the matrix of felsic tuff-breccia and cross-cutting felsic and intermediate tuff and lapilli-tuff. Chalcopyrite occurs in a few instances as specks, stringers and seams associated with pyrrhotite and pyrite.

The geological setting of the Tahoe Lake property, including the hydrothermally altered intermediate to felsic pyroclastic rocks and folded chert magnetite iron formation with associated grunerite-chlorite-gamet alteration indicates the potential for gold and base metal mineralization.

Work in 2006 consisted of line cutting and reconnaissance ground geophysical (magnetic and HLEM) surveys across five AeroTEM II anomalies identified in 2005. Four conductors were identified on the ground that could be considered drill targets. Three of these are associated with strong magnetic anomalies thought to be iron formation related. The fourth conductor occurs in the vicinity of felsic volcanic rocks and may be prospective for massive sulphide mineralization.

It is recommended that the immediate area of the four target anomalies be geologically mapped in order to prioritize them for diamond drilling.

INTRODUCTION

Candor Ventures Corp. (Candor) wholly owns three contiguous claims totaling 48 claim units in the MacDowell Lake area of Ontario. Previous work by Candor had identified helicopter-borne electromagnetic anomalies on the property. The property is considered to be prospective for volcanogenic massive sulphide (VMS) mineralization.

This report describes the results of horizontal loop electromagnetic (HLEM) and magnetic surveying completed during October, 2006 and makes recommendations for additional work.

LOCATION AND ACCESS

The Tahoe Lake property is located approximately 170 kilometers north northeast of the town of Red Lake, Ontario (Figures 1). The property is located in the Red Lake Mining District on the Mattson Lake Area (G-1819) claim map sheet, NTS 53CI7, and is centered on co-ordinates 5 800 OOON / 512 500E (UTM Zone 15, NAD83).

Access to the Tahoe Lake property is best by float or ski plane from the town of Red Lake. Since Tahoe Lake is too small to land on, access is from Mattson Lake and then north by foot along an old winter road for 3.0 kilometres to Tahoe Lake. The main winter road from Red Lake to North Spirit Lake is located approximately 15 kilometres to the west. The First Nations settlement of MacDowell Lake is located 17 kilometres to the south on the southwest shore of MacDowell Lake. The North Spirit Lake First Nations settlement is located 22 kilometres to the northwest on the southwest shore of North Spirit Lake.

PROPERTY DESCRIPTION

The Tahoe Lake property consists of three unpatented and unsurveyed mineral claims (3004452-3004454 incl.) totaling 48 units and 768 hectares (see Table 1 and Figure 2). The property is wholly owned by Candor.

GEOLOGICAL SETTING

The following is taken from Waldie (2004).

Regional Geology

The North Spirit Lake greenstone belt lies 170 kilometers north northeast of the

town of Red Lake, within the southwest part of the Sachigo Subprovince. The belt

is elongated northwest for 40 kilometers and attains a maximum width of 17

kilometers.

The North Spirit Lake belt comprises a variety of 3.02-2.73 Ma ultramafic to

felsic volcanic rocks and abundant metasedimentary rocks that have been

assigned a number of assemblages by Thurston et al. (1991) and updated by Stone

(1998). Refer to Table 2a and Table 2b and Figure 3 for more information.

Volcanics constitute a volumetrically important part of the North Spirit Lake belt

with felsic to intermediate rocks exposed over a larger area than mafic to

intermediate rocks. Ultramafic rocks are restricted to the northeastern edge of the

belt (Wood, 1980). The ultramafic volcanics often show spinifex texture. Mafic to

intermediate volcanics show the presence of feldspathic minerals on weathered

crust. Intermediate to felsic volcanics often contain recognizable phenocrysts of

quartz and/or feldspar.

Isoclinally folded volcanics and metasediments have been intruded by stocks,

dikes and sills of ultramafic, mafic, intermediate and felsic igneous rocks.

Numerous northwest trending faults (sub parallel to the regional Bear Head Fault)

transect the North Spirit Lake belt with subordinate northeast faults in the

southern portion of the belt.

Rocks of the North Spirit belt have been metamorphosed to greenschist facies

metamorphic rank, except those close to the Margot Lake intrusion (northwest

side of belt) where the metamorphism is of homblende-cordierite facies rank

(Wood, 1980).

Spirit Lake belt is interpreted to be synformal.

Features of the North Spirit Lake belt indicate that the rocks were formed in an extensional or transtensional setting between 3020 and 2730 Ma in a back-arc environment behind the main arc developing in the region of the Uchi Subprovince (Corfu et al., 1998).

In the eastern part of the Red Lake greenstone belt, complex Au-hosting deformation zones formed under a regime of northeast directed shortening (Zhang et aI., 1997). A similar northeast directed compression could explain the southeast trending antiforms and synforms of the North Spirit greenstone belt. This local direction is perpendicular to the dominant northwest compression throughout the Superior Province (Corfu et al., 1998).

Local Geology

The details of the geology in the vicinity of the Tahoe Lake property are poorly known because of the low outcrop density and the major northwest trending faults that are expressed as zones of intense shearing. Rock types consist of mafic to intermediate volcanics and pyroclastics, intermediate to felsic volcanics and pyroclastics, clastic metasediments and chemical metasediments. The following is summarized for Wood (1980 and 1988).

Rock Types

Mafic to intermediate volcanics in the vicinity of Tahoe Lake are fine grained, foliated flows generally without original textural characteristics. There are however pillowed, amygdaloidal and coarse-grained flows and some thickly laminated mafic tuffs documented. The volcanic rocks are dark grey-green on fresh surfaces and weather dark green to green-black.

Intermediate to felsic rocks near Tahoe Lake generally consist of massive flows and pyroclastics that differ markedly in fragment size. All the flows weather to a light grey or buff colour and are shades of grey or black on the fresh surface. The felsic flows in the Tahoe Lake area are tough and splintery on outcrop, which is a reflection of their strong silicification and/or albitization compared to similar volcanics in the area. Sericite alteration is well developed in the area, which is in marked contrast to the rest of the region. Pyroclastic rocks consist of lapilli-tuff and tuff-breccia with ellipsoidal fragments. They are similar to the flows around Tahoe Lake in that they are more siliceous that other pyroclastics rocks in the area. Geochemically, outcrops of intermediate pyroclastic rocks south and east of Tahoe Lake are strongly altered as highlighted by their high Hashimoto index (81%), which is indicative of altered rocks associated with VMS mineralization. Drilling by The Hanna Mining Company (see History section above) indicated

8

that the intermediate to felsic rocks contain alteration minerals such as grunerite, chlorite, garnet, sericite, carbonate, epidote and biotite. This indicates that the rocks have experienced high fluid flow and hydrothermal alteration.

Clastic metasediments consist of lithic wacke and mudstone. The lithic wacke units are fine grained and only weakly metamorphosed. No sedimentary structures other than bedding were noted. The rocks weather to a light brown to grey-brown colour. Mudstone units consist of shale and siltstone and are medium to thinly bedded. These rocks are dark grey to black on the fresh surface and weather to a brown colour. It is important to note that all metasediments in the Tahoe Lake are muscovite/sericite-bearing. This is in sharp contrast with most of the metasediments in other areas that lack muscovite/sericite or other potassium-rich minerals.

Chemical metasediments consist of chert, ferruginous chert and chert magnetite iron formation. Chert is typically layered from 1 mm to several centimetres and weathers grey to grey-black. Ferruginous chert weathers yellow-brown, due to sulphides, and chert magnetite iron formation weathers black.

Metamorphism

The metamorphism in the area of the Tahoe Lake property is interpreted as low pressure (below 3-4 kilobars) and at temperatures between 350 to 6500 C representing greenschist to cordierite-amphibolite facies (Wood, 1988).

Structure

The Spirit Lake belt is assumed to be a synclinal structure based on limited facing directions. Due to the extensive overburden cover in the area of the Lac Seul Moraine, correlation of the stratigraphic units in the area of the Tahoe Lake property is difficult. The numerous north northwest trending faults in the area also complicates the geology.

PREVIOUS WORK

Previous Work by Other Parties

Government Mapping

The first mention of prospecting in the North Spirit Lake area was by the Ontario Department of Mines (Hurst, 1930). In 1937, Bateman (1939) made a general reconnaissance geological survey of the area at a scale of 1 inch to 1 mile. This work defined a sedimentary-volcanic belt extending southeast from North Spirit

9

Lake through Hewitt Lake to MacDowell Lake. In 1960 and 1962, the Geological Survey of Canada perfonned reconnaissance mapping of NTS area 53C (Donaldson, 1961; 1969), which did little to change Bateman's 1939 map.

The most recent mapping in the area of the Tahoe Lake property is by Wood (1980 and 1988). This work was carried out in the summers of 1972-1973 and 1975 respectively at a scale of 1 inch to 'l'4 mile. Another geological report by Wood (North Spirit Lake, 1977) covers the area to the north.

Published regional maps of the area include Map 2262 (Favourable Lake - Berens Lake, 1973) at a scale of 1 inch to 4 miles and Map P.3382 (North Spirit Lake, 1998) at a scale of 1 :250,000.

Regional Exploration

Mineral exploration activity in the general region began in the 1920's with the first documented discovery of gold in 1936 on the south shore of North Spirit Lake, as described by Bateman (1939). Several companies explored extensive banded iron fonnation on the southeast shore of North Spirit Lake from 1953 to 1970. In 1977, Cominco Limited flew an airborne magnetic survey of the belt (not filed for assessment) and ground geophysical, geologic and geochemical surveys and diamond drilling by a variety of companies ensued (Stone, 1992). Most exploration was directed at gold and base metals in mafic to ultramafic volcanic and metasedimentary rocks on the east side of the North Spirit greenstone belt.

Property Exploration

The area of the Tahoe Lake property has seen minimal mineral exploration with the only documented work by The Hanna Mining Company (Muhic, 1976, 1977). This work involved line cutting, geological mapping, 18.8 line kilometers of ground magnetic and Max-Min surveys and 512 meters of diamond drilling in six holes.

Work in the area by The Hanna Mining Company was prompted by Ontario Department of Mines Preliminary Map P.1183 (Wood, 1976) that indicated the presence of felsic volcanic tuff and tuff breccia in the vicinity of Tahoe Lake. A reconnaissance Radem VLF survey in the summer of 1976 discovered a conductor east of Tahoe Lake. Subsequently, the work mentioned above was carried out and delineated six electromagnetic anomalies (Muhic, 1976). It is believed that these anomalies were drilled by holes TL-77 -1 to TL-77 -6 by The Hanna Mining Company. Sulphide mineralization consisting of pyrrhotite, pyrite and minor chalcopyrite was intersected in all the drill holes.

10

Geology

The geology of the Tahoe Lake property (Muhic, 1976) was noted as consisting of a series of basic lavas, intennediate tuffs, rhyolite tuffs and tuff-breccias. Lean chert magnetite iron-fonnation and associated siliceous metasediments occur with the felsic and mafic volcanics. The rocks are defonned and sheared especially in the northern portion of the property. An inferred fault runs approximately through the centre of the property and trends subparallel to the baseline of the grid (355°).

Geophysical Surveys

The 18.8 line kilometer magnetic survey was perfonned using an Mf-2 Fluxgate magnetometer which delineated several north to north-east trending magnetic anomalies (Muhic, 1976). The strongest anomalies, due to magnetite-chert iron fonnation, average 15 to 30 meters in width and are continuous along strike for 1,000 meters.

The electromagnetic survey was perfonned on the same grid lines and the magnetic survey. Detailed infonnation and maps of this survey were not available in the assessment records. It is assumed that the drill holes targeted the electromagnetic anomalies.

Diamond Drilling

The 512 meter, six hole diamond drill program (TL-77-1 to TL-77-6) was carried out in the winter of 1977 to test the electromagnetic and associated magnetic anomalies identified the previous fall (Muhic, 1977). The holes average 85 meters in length with the deepest being 135 meters. Core recovery was excellent, averaging 98%.

All of the holes intersected felsic volcanics and pyroclastics (tuff to tuff-breccia) with intennediate lapilli-tuff noted in most of the drill holes. Other lithologies intersected include banded chert magnetite iron fonnation and silicate facies iron fonnation. Andesite was intersected in only one hole. All of the drill holes intersected sulphide mineralization consisting of massive seams, stringers and disseminations of pyrrhotite, pyrite and minor chalcopyrite. No assays or sample intervals are reported on The Hanna Mining Company drill logs.

The main alteration minerals observed in the drill holes includes (in order of abundance) grunerite, chlorite, gamet, sericite, carbonate, epidote, biotite and quartz-carbonate veinlets. Mineralization includes (in order of abundance) pyrrhotite, pyrite and chalcopyrite. Graphitic bands and seams occur in three of the holes (TL-77-2, 5 and 6) Grunerite occurs as bands, seams, stringers, veinlets

11

and rimming fragments. It is noted most often associated with felsic tuff and tuff­breccia units as well as iron formation. The occurrence of grunerite in iron formation indicates the rocks have been altered and possibly mineralized. Grunerite associated with felsic volcanics and pyroclastics is rarely documented and its significance unknown.

Chlorite and garnet generally occur together in the matrix of felsic tuff-breccia, often associated with pyrrhotite and pyrite. Chlorite also occurs as fracture fillings.

Garnet, in addition to occurring with chlorite and sulphides in the matrix of felsic tuff-breccia, occurs as scattered disseminated grains in mafic rocks.

Sericite is generally noted as occurring pervasively in felsic volcanic and pyroclastic rocks.

Carbonate is noted as either pervasive or as stringers in felsic and intermediate rocks.

Epidote was only observed in a few cases, generally as stringers and seams.

Biotite was noted in only one hole associated with bands of mafic rocks containing garnets.

Pyrrhotite and pyrite generally occur together (5: 1 ratio of pyrrhotite to pyrite) as massive seams (cm-dm scale), stringers and disseminations in both the matrix of felsic tuff-breccia and cross-cutting felsic and intermediate tuff and lapilli-tuff.

Chalcopyrite was noted in holes TL-77-5 and 6 as specks, stringers and seams associated with pyrrhotite and pyrite.

Previous Work by Candor Ventures

Mtec Contracting Inc. of Murillo, ON completed magnetic and HLEM surveying to ground truth the AeroTEM II anomalies (Milani, 2006). A total of 4,000m of magnetic readings were taken at 12.5m spacings along the lines using a GEM Systems GSM-19 proton precession magnetometer measuring variations in the total field with a sensitivity of 0.1 nT. The diurnal variations were monitored and recorded using a GEM base station.

The HLEM survey was completed using an Apex Parametrics Limited MaxMin I instrument in the horizontal co-planar mode with a 100m coil separation. Measurements of the in-phase and quadrature values were taken at 25m stations at 1777 mHz and 3555 mHz frequencies. A total of3,500m ofHLEM surveying was completed.

The description and specifications of the instrumentation used can be found in Appendix 1.

INTERPRETATION

The reader is referred to the stacked profiles for each of the lines surveyed which can be found in Appendix II.

Line "A"

One strong but thin (~ 5m) conductor located at 4+10 N was detected. It dips moderately to the north and has a depth to the top of the conductor of about 10-15m. There is little or no significant magnetic association.

Line "B"

Two conductors were detected on this line. A strong but thin (~ 5m), steeply north dipping conductor was detected at 3+35 N. The depth to the top of this conductor is estimated to be 5-10m. There is a strong positive magnetic correlation.

A second, much weaker conductor was detected at 4+85 N. It is thin (~ 5m) and may also dip steeply to the north but interference from the conductor crossing the line at 3+50 N clouds this interpretation. This conductor closely flanks a strong magnetic feature.

Line "C"

Two features thought to represent end effects of other conductors were detected at about 2+15 N and 4+60 N. The southern portion of the line crosses a broad, elevated magnetic feature.

Line "D"

A broad, possibly compound feature was detected on this line. A moderately strong, possibly steeply north dipping conductor was detected between 2+75 N and 3+00 N. This conductor is thought to have a depth of about 30m. A thinner parallel, weaker feature crossing the line at 3+75 N was also detected. A very weak, possibly overburden related feature exists at about 5+60 N. The magnetic correlation along this line is generally positive but somewhat erratic.

Line "E"

A relatively broad (10-20m) and strong conductive feature was detected centered

15

about 3+30 N. It is interpreted to have a depth of about 30-40m and to dip steeply to the south. It appears to flank a strong positive magnetic feature lying immediately to the south.

A second, much weaker and thinner (S 5m), possibly fault related conductor was detected at about 4+50 N. It also appears to flank a strong positive magnetic feature.

CONCLUSIONS AND RECOMMENDATIONS

The combined HLEM and magnetic surveys completed on the Tahoe Lake property have successfully located the AeroTEM II anomalies on the ground. Four possible drill targets have been identified. It is recommended that lines "A", "B", "D" and "E" be geologically mapped prior to drill testing. Particular attention should be paid to evidence of alteration in the surrounding lithologies which might increase the relative attractiveness of these targets.

Those targets on lines "B", "D" and "E" are related to strong magnetic features and are thought to be prospective for iron formation hosted mineralization, particularly in the vicinity of faulting. The conductor on line "A" is located in the vicinity of felsic volcanic rocks and may be prospective for massive sulphide mineralization.
