Copper Lake Resources updates diamond drilling program on its Marshall Lake volcanogenic copper-zinc-silver massive sulphide property in northern Ontario

TORONTO, November 29, 2021 (GLOBE NEWSWIRE) – Copper Lake Resources Ltd. (TSX-V: CPL, Frankfurt: W0I, OTC: WTCZF (“Copper Lake” or the “Company”) is pleased to provide an update on the diamond drilling program currently undertaken on its volcanogenic copper-zinc massif. Marshall Lake Silver Sulphide Property (VMS), located in northern Ontario, as well as the status of its joint venture with Rainy Mountain Royalty Corp. The Company also reports on the recent exercise of warrants providing 400,000 $ in additional program funding.

The primary focus of the current drill program is a large, strong, untested Induced Polarization (IP) anomaly located adjacent to and below Billiton’s Zinc-Copper-Silver SMV deposit., with a secondary focus on other base metal occurrences on the property that have had little or no historical drilling and those that are open at depth (see Copper Lake press releases dated September 28, 2021 and September 7, 2021).

Diamond Drilling Update

Due to difficult weather conditions and logistics due to heavy snowfall in early winter, milder temperatures and wet boggy soil near the Billiton deposit, only one drill hole was completed. to date, in the planned drilling program of at least 3,000 meters. Hole ML-21-01 was drilled to a depth of 400 meters and tested the down-dip projection of the Billiton deposit and an associated PP anomaly (see figures 1 and 2).

The projected extension at depth of the main zone of the Billiton deposit was intersected over a length of core of 7.65 meters (190.35 – 198.00 meters downhole). It was largely composed of disseminated to highly disseminated pyrite, with associated chalcopyrite and sphalerite, locally containing narrow bands of semi-massive sulphide consisting of pyrite, chalcopyrite and sphalerite, hosted in fragmentary coarse felsic rocks. strongly chloritized and rich in biotite and lapilli tuff. In addition, 2 zones of disseminated pyrite with lesser sphalerite and chalcopyrite were encountered at a shallower depth in the borehole, considered to be zones of alteration of the lower wall linked to the main deposit at Billiton. Core logging and sampling from this hole has been completed – assay results will be released as they become available.

Deep Induced Polarization (PI) Target

The primary target for upcoming drill holes ML-21-02, ML-21-03 and ML-21-04 is a large IP anomaly (high conductivity, low resistivity, high chargeability), located below and next to the main copper. by Billiton. – massive zinc-silver sulphide deposit (historical resource of 2.2 MT at 1.3% copper, 4.2% zinc and 2.5 silver opt1). This priority target has dimensions of 800 x 300 x 300 meters, is located between 150 and 450 meters below the surface and represents a new target never tested before by diamond drilling (see figure 2).

Drill hole ML-21-02 will test an undrilled VTEM conductor, presumably tied to the top of the deep IP anomaly, while holes ML-21-03 and ML-21-04 are intended to test the core of the same great depth PP Anomaly, at a vertical depth of about 350 meters. Since the Marshall Lake greenstone belt is a tightly folded VMS terrain, it appears that the main Billiton deposit sits on a fold limb, suggesting that the largest deep PP anomaly is located in a hinge of fold to the east and plunging down the known Billiton. deposit. As this is typically where the largest and thickest deposits are found in folded VMS terrains, the prospects of encountering a much larger sulphide body associated with the deep IP target look very promising.

Recent colder temperatures and freezing overnight conditions have allowed the construction of corduroy trails and drilling platforms over long stretches of swampy terrain, accessing the next 3 planned drill holes. It is expected that the access trails and drilling platforms for these 3 drill holes will be ready for drilling placement over the next few days.

Deeds Island target and other VTEM targets

The Marshall Lake Belt clearly has potential for the discovery of several VMS deposits, and there are several attractive targets that have received little or no historic drilling. The Deeds Island target includes an 800 meter long zinc bedrock geochemical anomaly (up to 1000 ppm zinc) closely associated with a strong extensive alteration zone of garnet and actinot and EM conductors coincident airborne. It is located 6 km east of the Billiton deposit in younger rocks and represents another potential VMS target on the Property. More importantly, this very promising target has never been drill tested in the past and is a very promising second target for testing in the current program.

Several other VTEM conductors on the Property which were not drilled and located in favorable stratigraphy, were modeled for future diamond drilling programs. At least two of these VTEM conductors are located in younger rocks east of the Billiton deposit, while others are located west of the Billiton deposit near the RM and RMZ zones, copper-rich occurrences. that look like areas of wall fillets.

Marshall Lake Joint Venture

The company’s joint venture partner, Rainy Mountain Royalty Corp., which owns a 25% stake in the original Marshall Lake property, has confirmed that it will participate in the current exploration program and contribute its share of the program. exploration budget of $ 1.2 million.


As of July 31, 2021, the Company had a total of 64,518,301 warrants outstanding. This total includes 16,133,333 warrants with an expiration date of December 30, 2021 and an exercise price of $ 0.05. Since July 31, 2021, holders of warrants of December 31, 2021 have exercised 6,000,000 warrants and holders of warrants of May 8, 2022 have exercised 2,000,000 warrants for a total proceeds of $ 400,000.
