Exploration History

'Around 1950, prospectors working for Noranda Mines, Limited, discovered a copper-nickel deposit between Denmark and Atikwa Lake. This discovery initiated extensive staking and prospecting around Denmark Lake.' (Kenora Historical File 52F/05NE00055/66, Denmark Lake - Ref. CU 2) 'In July, 1968, a 3-drill hole investigation of anomalies 3, 4 & 5 were commenced on the patented portion (4 claims) of the overall Nilson-Gauthier claim group. * see 'Deposit Comment' - Mineralization for assay results. (Kenora AF 52F/05NE, K-1, Huston & Associates)

Geology

Province: Superior

Geological Age: Precambrian  



Geology Comments

Feb 16, 2011 (J Bongfelt) - 'The intrusive complex at Denmark Lake consists of peridotite, pyroxenite gabbro, diorite, quartz diorite, granodiorite and amphibolite, with enclosed remnants of metavolcanic rocks. Each rock type is compositionally and texturally variable and is intimately associated with other rock types. The oldest rocks of the complex appear to be ultramafic, with gabbro, diorite, quartz diorite, and granodiorite being successively younger.' (Kenora AF 52F/05NE, KK-6, Canadian Arrow Mines Ltd., Geological Report)




Lithology Comments

Feb 16, 2011 (J Bongfelt) - 'The general area around Denmark Lake is underlain by intermediate to basic lavas of Keewatin type, and interbedded sediments and pyroclastics. There are a number of rock types intruded into this sequence, including titaniferous hornblende-biotite granite, diorite, gabbro and peridotites. Zones and patches of disseminated chalcopyrite and nickeliferous pyrrhotite occur in the gabbroic phase of the basic intrusives. (Kenora Historical File 52F/05NE00055/66, Denmark Lake - Ref. CU 2)

Mineralization Comments

Feb 16, 2011 (J Bongfelt) - 'A number of zones of disseminated chalcopyrite and nickeliferous pyrrhotite were discovered in basic intrusive bodies. Two such deposits considered worthy of mention by J.E. Thomson were: 1) The F. Thomson showing, which was optioned to The International Nickel company of Canada Limited, in 1951. Only surface stripping was done. The best grab sample assayed 0.34% Cu and 0.06% Ni. 2) The Anderson property, which was optioned to F. Thomson. Only surface stripping was done; the best grab samples assaying 0.10% Cu and 0.46% Ni.' (Kenora Historical File 52F/05NE00055/66, Denmark Lake - Ref. CU 2) 'The Denmark Lake Showing was noted first time in 1951, outcrops were stripped and grab samples assayed: 0.06% Ni and 0.34% Cu; 0.46% Ni and 0.1% Cu.' (Kenora AF 52F/05NE, KK-6, Canadian Arrow Mines Ltd., - Geo Report - Previous Work, Denmark Lake Prospect) July, 1968 Drill Results re Nilson-Gauthier DD Hole 6-68: .13% Ni DD Hole 7-68: 'abandoned at a drilled depth of 130.0 feet due to excessive caving' DD Hole 8-68: .10% Ni & 0.20 oz./ton Au (Kenora AF 52F/05NE, K-1, Huston & Associates - Report on Diamond Drilling I.P. Anomalies 3, 4 & 5)
