Exploration History

Pre-1952 - separate claims in the group had passed through several owners, who had carried out surface prospecting at intervals over a period of at least 25 years. The prospecting included trenching and sinking pits, one of which, at the Acana No. 2 showing, was 35 feet deep. 1936 a silica deposit produced a small tonnage of silica for use in the Cuniptau smelter situated in Strathy township. 1952: Acana Mines Ltd. - electrical resistivity and magnetic surveys made of the group and later a geological survey. 1953: Cheskirk Mines Ltd.: DD-8-2264 ft. In 1954- Quebec Metallurgical Industries Ltd. 9-DD. 1956: Central Milner Mines Ltd. –DD-2. 1957: Huclif Porcupine Mines Ltd. surface work and drilled 4 drillholes; 1957- Reef Explorations Ltd. – EM survey, 4 trenches and 8-DD; 1961- Danlou Mines Ltd. carried out a small amount of trenching and drilled three holes on a gold-bearing vein. 1965- Ajax Minerals Ltd. - magnetometer survey and an electromagnetic survey; IP and resistivity. 1966: Geophysical Engineering and Surveys Ltd. - magnetometer, a self-potential and a geological survey. Reef Explorations uncovered the highest assays which were 1.14% Ni and 0.69% Cu across 23 ft., on claims T31459 /T31459

Lithology

Lithology Comments

Nov 03, 2017 (A Wilson) - The Acana Mines Ltd. Showings Nos. 1 to 10 are of the "copper-nickel in pyrrhotite, chalcopyrite, pyrite mineralization type mentioned previously”. Chalcopyrite, pyrite, and pyrrhotite make up to 50 % of widths to 3 feet along the 25 feet of exposure in a shallow trench. The mineralization is in a shear zone striking north, and dipping 75°W. Showing No. 2 is in claim T.31459 ; this claim occupies approximately the same position as former claim JS 59. The showing has given the highest sampling results and has had more work done on it than any other on the property. Chalcopyrite, pyrite and pyrrhotite mineralization occurs in a sheared zone along a contact between gabbroic rocks to the east and volcanics to the west. The showing had been explored by a 35-foot pit which had been excavated many years before. Reef Explorations Ltd. reported (Reef Explorations Ltd., Assessment Work Reports, Best township) that an exposure of sulphides in the 35-foot pit assayed 1.55% nickel and 0.84% copper across 3.0 feet. In the trench 50 feet from the pit and designated RE on Figure 5 assay returns of 0.55% copper and 0.32 nickel across 25 feet were reported. In the trench 90 feet from the pit and designated RE 2 on Figure 5 assay returns of 0.69 % copper and 1.14% nickel across 23 feet were reported. Showing No. 3 (in the northeast corner of claim T.31459) was exposed by a pit about 15 feet deep. On the dump of the pit pyrite, pyrrhotite and chalcopyrite is present both as heavy and as disseminated mineralization; galena and dark sphalerite are present in minor amount. Showing No. 5 (in claim T.31705) is a mineral-bearing shear along the contact of a Matachewan diabase dike. Chalcopyrite, pyrite, and pyrrhotite are contained. The presence of nickel and platinum group metals is reported (Acana Mines Ltd. Assessment Work Reports, Best township). The assay returns of a selected sample taken by the writer and assayed by the Laboratory Branch, Ontario Dept. of Mines, gave an assay return of 0.04 oz. platinum per ton and 0.08 oz. palladium per ton. Presumably the platinum group metals are not distributed uniformly; local prospectors have reported obtaining assay returns of platinum group metals over l oz. per ton from this showing. Showing No. 6 (in claim T.31703) is a fractured and sheared altered diabasic rock containing chalcopyrite, pyrite and pyrrhotite. This showing was tested by Cheskirk Mines Ltd. drillhole C-4. Sampling of what was regarded as the downward extension of the showing between footage 194.1 and 196.8 in the drillhole was reported (Cheskirk Mines Ltd. Company Report) to give assay returns as follows: copper 0.29 percent, nickel 0.22 percent, cobalt 0.038 percent, gold 0.005 oz. per ton, silver 0.15 oz. per ton, and platinum trace. Showing No. 10 in claim TRT.5165 is reported by McCannell (Acana Mines Ltd. Assessment Work Reports, Best township) to be a silicified shear, in dacitic tuffs with some pyrite, pyrrhotite and minor chalcopyrite.
