Copper Lake explores for gold, copper, zinc and nickel base metals with significant precious metal credits including platinum group metals and cobalt in Northwestern Ontario.
Based in Thunder Bay, Northwest Ontario; Copper Lake looks to develop properties where a substantial amount of historical exploration has already been undertaken. It aims to add value by deploying modern geophysical tools and combining this with extensive geological field work. Using these methodologies Copper Lake has since 2010 developed its two advanced exploration properties Marshall Lake and Norton Lake.
Marshall Lake which is Copper Lakes primary focus is a copper, zinc, silver and gold exploration project located 30 km west of Nakina and approximately 252 km northeast of Thunder Bay, Ontario. The closest towns to the property are Armstrong and Nakina both of which are access points for the Trans Canada, CNR railway. Road access is by all weather gravel roads off Hwy 11 crossing the main CNR rail line 22 km to the south of the Property. The Marshall Lake Property is located within the Thunder Bay Division, northeast of Lake Nipigon.
Norton Lake is a nickel, copper, cobalt, and platinum group element deposit which is located about 50 km northeast of Fort Hope, Ontario, and about 400 km northeast of Thunder Bay, Ontario. Access currently is by helicopter from either Armstrong or Nakina.
Situated in the Kenora and Patricia mining divisions the Company holds a 25% interest rising to 100% interest in the following high grade near surface gold properties all of which are located in the prolific greenstone belt of NW Ontario.
Recent prospecting in the area has returned grab samples with gold assays of up to 340 g/t over the area which shows size potential. Channel sampling and limited drilling have returned significant results from limited follow-up. Copper Lake feels there is strong potential for the area to host numerous, significant deposits.
Mine Lake Gold Property
The Mine Lake claims cover three prospects, namely Mine Lake, Thomas Lake and the Stewart Contact Zone. Historically, the Mine Lake and the Stewart-Contact Zone saw extensive trenching, blasting of several pits, and the sinking of two shallow shafts with limited underground development.
- Mine Lake Prospect
Grab samples returned gold assays of up to 29.0 g/t. Historical trenching and channel sampling has returned 6.90 g/t gold over 3.2 metres including 20.1 g/t gold over 1.0 metre. The northwest trending shear zones are interpreted to represent gold-bearing dilational structures extending from the main north-south deformation zone. These structures have not been drilled.
- Thomas Lake Prospect
Previous exploration work at the Thomas Lake area has outlined at least two, near parallel north south striking shear zones exposed over a 1500 metre strike length and up to 50 metres in width. Grab sampling of exposed quartz vein zones assayed gold of up to 62.80 g/t. The vein zones are hosted by strongly sheared quartz porphyry rocks measuring up to 15 metres in width. The vein zone remains open along strike. Historical trenching has returned values of up to 15.4 g/t Au over 0.5 metre.
- Stewart-Contact Prospect
Historical sampling has returned gold assays of up to 55.6 g/t from outcropping quartz veins (up to 40cm) that contain visible gold
Queen Alexandria Gold Property
Quartz veining in chlorite-carbonate alteration, averaging 0.5m wide has been located within a major NNE-SSW shear zone which was historically mined via the Queen Alexandria shaft (1904) which occurs on the property. The property has not been subjected to modern exploration with grab samples from the waste dump at the old shaft returning gold assays of up to 28.8g/t, 140.9g/t, 340.8 g/t and 89.3g/t. Grab sampling of outcrops within a trench located 25m from the main vein returned gold assays of up to 9.26g/t, 5.05g/t and 14.31g/t.
Grand Chibougamau Gold Property
Grab sampling of the zones returned gold assays of up to 2.40g/t and 6.51g/t from the Main Zone and up to 21.0g/t from the North Zone. Drilling from two holes completed in 1987 on the Main Zone returned gold assays of 3.45m @ 5.29g/t and 2.78m @ 6.22g/t. No subsequent follow-up has been completed.
Centrefire-Redhat Gold-Copper Property
Redhat returned trench channel sample gold results of 18m @ 1.1g/t and drill intercepts of 1.2m @ 9.17g/t and 1.5m @ 3.36g/t. Grab sampling at the Centrefire zone returned grab assays from outcrop of up to 23g/t Au which has not been followed up.
