Copper Lake Drilling Yields 8.69% Zinc-Equivalent Over 4.90 Metres and 8.03% Zinc-Equivalent Over 3.00 Metres at Marshall Lake Copper-Zinc-Silver-Gold VMS Property, Northern Ontario
TORONTO, Feb. 15, 2022 (GLOBE NEWSWIRE) -- Copper Lake Resources Ltd. (TSX-V: CPL, Frankfurt: WOI, OTC: WTCFZ) (“Copper Lake” or the “Company”) is pleased to report encouraging initial assay results from its ongoing diamond drilling program, being undertaken on its Marshall Lake copper-zinc-silver-gold volcanogenic massive sulphide (VMS) property (the “Property”), located northeast of Thunder Bay, Ontario.
The primary focus of the current 3,000 metre drill program is a large, untested Induced Polarization (IP) anomaly (“deep IP target”), with a secondary focus on the Billiton deposit and other base-metal occurrences on the Property that have seen minimal to no historic drilling. The highlight of the recent drilling was the recognition of a new copper-zinc mineralized zone parallel to the main Billiton Zone.
Drill Results
The initial drill hole completed in the current program, Mar-21-01, tested the Billiton deposit (historic resource of 2.2 MT at 4.2% zinc, 1.3% copper and 2.5 opt Ag1) between two widely spaced shallow historic drill holes. The deposit was intersected at a vertical depth of approximately 70 metres, yielding an intercept of 5.26% zinc, 1.17% copper, 0.12% lead, 59.65 g/t silver and 0.03 g/t gold (8.69% ZnEQ) over a core length of 4.90 metres. This intercept confirms both the tenor and width of base and precious-metal mineralization, obtained in the historical drilling, testing the Billiton deposit.
Deeper in the hole, at a vertical depth of 170 metres, a second parallel zone of significant base-metal mineralization was intersected yielding 6.54% zinc, 0.40% copper, 0.08% lead, 41.50 g/t silver and 1.06 g/t gold (8.03% ZnEQ) over a core length of 3.00 metres.
Both zones comprise heavily disseminated to locally banded sphalerite, chalcopyrite and pyrite within intense biotite-chlorite altered, coarse-grained felsic volcaniclastic rocks. Intersected widths of mineralization are thought to be close to true widths. The deeper zone is of particular interest, in that it confirms the potential for the existence of a parallel zone of base-metal mineralization to the known Billiton deposit. Additional drilling and bore-hole EM surveying are clearly warranted, to determine the extent of this new zone of base-metal mineralization. The presence of stacked sulphide lenses would increase the mineral inventory and enhance the exploration potential of the Billiton deposit area.
Assays results for Mar-21-01 are tabulated below2.
| Hole No. | From (metres) | To (metres) | Length (metres) | Zinc (%) | Copper (%) | Lead (%) | Silver (g/t) | Gold (g/t) | ZnEQ3 (%) |
| Mar-21-01 | 88.10 | 93.00 | 4.90 | 5.26 | 1.17 | 0.12 | 59.65 | 0.03 | 8.69 |
| 192.60 | 195.60 | 3.00 | 6.54 | 0.40 | 0.08 | 41.50 | 1.06 | 8.03 |
Assay results for drill hole Mar-21-03 are anticipated to be received within the next 30 days. This hole tested a VTEM airborne conductor situated above the deep IP target, intersecting 2 well-mineralized zones containing heavily disseminated to semi-massive sphalerite, chalcopyrite and pyrite over core lengths of 2.67 & 3.74 metres, respectively (see Copper Lake news release of January 4, 2022 http://copperlakeresources.com/wp-content/uploads/2022/01/CPL-News-Release-22-01-Jan-3-Final-9pm-ex-core-pictures.pdf).
Upcoming Drilling
Following a short pause due to extreme cold weather, safety concerns stemming from it and the implementation of camp improvements, diamond drilling has resumed at Marshall Lake. Drilling is focused on testing the large new (800 x 300 x 300 metres), strong, untested deep Induced Polarization (IP) anomaly, situated adjacent and below the Billiton VMS deposit, that was identified in the recent survey disclosed in the Company’s news release dated September 7, 2021 (http://copperlakeresources.com/wp-content/uploads/2021/09/Sept-8-2021-News-Release-Combined-with-maps.pdf).
Gravity Surveys
The orientation gravity survey undertaken in the Billiton deposit - deep IP target area has been completed. Interpretation and modelling of the gravity survey data are currently being undertaken. Results will be released as they become available.
The gravity crew has now mobilized to the Deeds Island target, to assist in prioritizing drill targets over this large, prospective anomaly. It comprises a 1 km-long zinc bedrock geochemical anomaly, coincident with an extensive garnet-actinolite alteration zone and several airborne EM conductors. It is anticipated that the Deeds Island gravity survey will be completed within 2 weeks time.

ABOUT COPPER LAKE RESOURCES
Copper Lake Resources Ltd. is a publicly traded Canadian mineral exploration and development company with interests in two projects both located in Ontario. www.copperlakeresources.com
