Point Location Description: DDH CWM-13-001 from AFRI 2.54711

Location Method: Based on Assessment

Access Description: Access to the claims isvia Cameron Lake Road (an all-weather, gravel road) that departs east from Highway 71 about 30 km north of the town of Nestor Falls. The McLennan prospect is located at kilometre 7.5 on the Cameron lake road.

Exploration History

The McLennan prospect was discovered and staked by G.E. McLennan in 1944. The prospect was then optioned by Sylvanite Gold Mines Ltd. in 1945 and trenching, channel sampling and diamond drilling (14 DDH totalling 807.5 m) was carried out. Little work was completed until Falconbridge carried out a second diamond drill program in 1985 however the information on this program was kept internally and there were no assessment work submitted to the Government. Houston Lake Mining (HLM) followed up on previous drilling by having small drill programs in 2004, 2006, 2007 and 2008 totaling 8 drill holes as well as a more significant program of 10 drill holes in 2011. In 2006 HLM carried out an extensive Induced Polarisation geophysical survey over its tenements. 2013: Cameron Gold Operations Ltd. drilled 7 DDH totalling 425.6 m.

Geology Comments

Apr 27, 2017 (C Ravnaas) - The West Cedartree property is underlain by rocks of the Archean, Savant Lake-Crow Lake metavolcanic-metasedimentary belt in the Wabigoon Subprovince of the Canadian Shield. The property is situated within the Kakagi Greenstone Terrane which is separated from the Rowan greenstone terrane representing a different lithological package to the NW. The Kakagi and Rowan green stone terrains are separated by an offsetting significant regional structural feature the Pipestone-Cameron fault. This northwest striking, steeply northeast dipping fault is a significant zone of deformation and displacement which has been defined for over 100km of strike length and has characteristics similar to the regional “breaks” recognized in other Canadian Archean gold camps. The lithological package to the SW of the Pipestone-Cameron fault has been folded by an ENE plunging structure referred to as the Emm Bay syncline. The folding is conspicuous when examining the airborne magnetic image of the area as it is picked within the stratigraphy of the variably magnetic Kakagi gabbro sills. In total the Kakagi gabbro sills are made up of five sills, lithologically dominated by gabbro with smaller intercalated olivine pyroxenite and peridotite sub-units. The Stephen Lake stock represents the largest felsic intrusive unit in the West Cedartree project area. The stock is trending NNW sub-parallel to the Pipestone-Cameron fault, is lensoidal in shape and the lithological composition is granodiorite. The Stephen Lake stock is situated at the center of the Emm Bay syncline and intrudes into the Kagkagi gabbro sills and Intermediate to felsic volcaniclastic units.

Lithology

Lithology Comments

Apr 27, 2017 (C Ravnaas) - “The mineralisation is typified by quartz-albite-(Fe) carbonate vein with significant fine-medium grained pyrite present in a mafic volcanic host. At McLennan there is a correlation between sulphide percentage within the mineralised vein and gold assay.” (52F05SW SSS-1, 2.4711, Cameron Gold Operations Ltd, pg.7).

Aug 25, 2017 (Therese Pettigrew) - The McLennan gold zone is hosted by massive to pillowed mafic flows of the Snake Bay Formation which are intruded by feldspar porphyry dykes proximal to the lower contacts of the main Kakagi sill. The zone is slightly curvilinear and has an average strike of N45E steeply dipping to the east (Cutting and Anthony, 2005).

Mineralization

Mineralization Comments

Aug 25, 2017 (C Ravnaas) - Diamond drill hole CWM-13-003 assayed 3.70 g/t Au over 6.30 m and 5.20 g/t Au over 4.30 m. Diamond drill hole CWM-13-004 assayed 1.70 g/t Au over 2.0 m. Refer to assessment file Kenora 52F05SW SSS-1, 2.4711, Cameron Gold Operations Ltd, for complete list of significant assay results. GRADE: 0.21 OPT AU OVER 6 M ON SURFACE (original MDI entry).

Aug 25, 2017 (Therese Pettigrew) - Gold disposition at the Main Showing is associated with the alteration and replacement of greenstone by albite, quartz and carbonate with quartz carbonate veinlets along fracture zones. Mineralization is largely by pyrite, in estimated average amount of 2-3% up to about 10% and occurring as disseminations and irregular veinlets; minor chalcopyrite (less than 0.25%) also occurs. Visible gold was reported from Trench 1 and Trench 6. The Main Showing has a strike of about N46E and a steep easterly dip. The zone has been traced for at least 650 feet (198 m) (Davis and Morin, 1976). The best assays in 3 trenches were 0.85 oz Au over 1.7 ft, 0.4 oz Au over 3 ft, and 0.44 oz Au over 3.5 ft (Beard and Garratt, 1976). Drilling during the 2013 campaign returned results ranging from 0.62 to 6.41 g/t Au (AFRI 2.54711). Sylvanite’s DDH-2 from 1945 returned 1.35 oz Au over 3.5 ft and another section with 0.23 oz Au over 7.0 ft. The greatest hole width reported (DDH-9) is 0.16 oz over 10 ft (AFRI 52F05SW0115). Houston Lake Mining’s grab and chip samples returned values ranging from 1.29-15.55 g/t Au and averaged 4.75 g/t Au. Gold is associated with sulphides, brecciation, stringer sulphide veining and silicification. The McLennan zone is not well expressed in magnetic and weakly illustrated by VLF-EM surveys (Cutting and Anthony, 2005).
