VANCOUVER, BC / ACCESSWIRE / June 16, 2021 / Blackwolf Copper and Gold Ltd. ("Blackwolf" or the "Company") (TSXV:BWCG) is pleased to announce that assays from four drill holes have been received from the spring 2021 underground resource expansion and exploration drilling program from the Lookout Deposit at its 100%-owned Niblack copper-gold-silver-zinc VMS project, located adjacent to tidewater in southeast Alaska. This drilling is over 1,000 meters to the south of the historic Niblack Mine area where the Company recently reported high-grade, copper-massive sulphide mineralization (see Blackwolf Copper and Gold News Release, May 03, 2021).
Resource expansion drilling intersected much wider intervals than expected from previous modelling, with remarkably consistent polymetallic grades within the Lookout Zone. Exploration drilling down-dip of the deposit encountered encouraging base and precious metal intervals within the prospective massive sulphide horizon. Highlights of the drilling at the Lookout and Lookout Extension zones include:
- U21-226: 27.00 meters averaging 1.06% Cu, 1.87 g/t Au, 32.83 g/t Ag, 1.04% Zn or 3.08% Cu equiv.
including: 4.00 meters averaging 2.61% Cu, 4.93g/t Au, 76.58 g/t Ag, 2.34% Zn or 7.69% Cu equiv.
- U21-227: 32.60 meters averaging 1.03% Cu, 1.49 g/t Au, 26.54 g/t Ag,0.92% Zn or 2.67% Cu equiv.
including: 3.00 meters averaging 2.37% Cu, 3.29 g/t Au, 58.97 g/t Ag, 1.42% Zn or 5.78% Cu equiv.
Metal equivalency value is based on the following prices: US$3.25/lb Cu, US$1,600/oz Au, US$1.15/lb Zn and US$20.75/oz Ag; it is noted that no adjustments were made in the metal equivalency calculation for metal recovery. Prices taken as an average of research analyst's long-term metal prices forecasts, April 2021.
"Two drill holes were completed to test our revised geological model relating to the expansion of current Mineral Resources at the Lookout Zone and encountered substantially thicker intervals of mineralization than expected, with remarkable continuity between the drill holes. The consistent high-grade mineralization with excellent metallurgy and hosted in good ground conditions suggests that this area is potentially amenable to low-cost bulk underground mining," said Rob McLeod, President and CEO of Blackwolf Copper and Gold. "Additionally, the discovery of the Lookout mineralized horizon on the west side of the Bluebell fault is highly encouraging, greatly increasing the size potential of the deposit. Based on these results that have exceeded our expectations, Blackwolf has decided to initiate a significant upgrade of site facilities including camp, fuel storage, underground support and core processing that can accommodate greatly expanded programs at Niblack."
Assays have been received for four of five holes drilled during April's 1,810 meter program that targeted extensions to the current Mineral Resources from the Lookout Zone. Primary objectives of this program were: 1) resource expansion drill holes targeting massive sulphide mineralization approximately 300 meters away from the underground ramp; 2) exploration drill holes to test for the down dip extension of the Lookout mineralized horizon and exploration to the west of the Bluebell strike-slip fault, which runs shallowly oblique to the Lookout Zone. All drill holes successfully encountered mineralization. A fifth drill hole testing up dip of the Mineral Resource was stopped short of the mineralized horizon and will be completed during the next round of underground drilling.
The largest deposit on the Niblack Property, the Lookout Zone hosts a large trough of polymetallic semi-massive to massive sulphide mineralization. Hosting consistent copper-gold-silver-zinc mineralization throughout, this deposit is over 120 meters thick at its widest, potentially amenable to bulk-underground mining techniques. Current NI 43-101 Mineral Resources are 5.6 million tonnes of Indicated Resources averaging 0.95% Cu, 1.75 g/t Au, 29.52 g/t Ag and 1.73% Zn, with additional Inferred Resources of 2.4 million tonnes of 0.73% Cu, 1.42 g/t Ag, 21.63 g/t Ag and 1.17% Zn. A higher-grade core of Indicated Resources hosts 1.2 million tonnes averaging 1.7% Cu, 3.2 g/t Au, 62.6 g/t Ag and 3.8% Zn. Refer to disclosure below for further details on the company's NI 43-101 Mineral Resources Estimate. The deposit is open to expansion to the west and at depth.
High-grade Neoproterozoic VMS-style mineralization is hosted within a series of felsic volcanic flows and breccias, typically as stringer, semi-massive to massive chalcopyrite and sphalerite-rich replacement-style mineralization, commonly with additional pyrite. Metamorphic and structural deformation events have overturned the volcanic sequence and recrystalized the sulphide mineralization, resulting in good metallurgical recoveries. First-pass, unoptimized metallurgical test results from the Lookout deposit yielded recoveries, including: copper (94.3 to 94.9%) and zinc (90.2 to 93.3%) with very clean concentrates. Current test work that is underway is focused on boosting the reasonable initial precious metal recoveries of 72.6 and 76% for gold and silver, respectively (see Blackwolf News Release, February 24, 2021).

2021 Drill Results
During March and April 2021, five holes totaling 1,810 meters of NQ2 core were completed using underground diamond drills operated by Morecore Drilling of Stewart, BC. Two resource expansion holes were completed, U21-226 encountered 27.00 meters of 1.06% Cu, 1.87 g/t Au, 32.83 g/t Ag and 1.04% Zn or 3.08% Cu-equivalent, including a higher-grade interval of 4.0 meters averaging 2.61% Cu, 4.93 g/t Au, 76.58 g/t Ag and 2.34% Zn or 7.69% Cu-equivalent. U21-227 intersected a very similar interval in thickness and grade, encountering 32.6 meters of 1.03% Cu, 1.49 g/t Au, 26.54 g/t Ag and 0.92% Zn with a higher-grade interval of 3.00 meters averaging 2.37% Cu, 3.29 g/t Au, 58.97 g/t Ag and 1.42% Zn or 5.78% Cu-equivalent. This area was previously interpreted to host mineralization three to five meters in width. The mineralized intervals in U21-226 and 227 are approximately 35 meters apart.

Drill holes U21-225 and 228 are exploration holes drilled up and down-dip, respectively, as step-outs from an isolated massive sulphide interval in historical hole U-074, which intersected 1.5 meters averaging 2.0% Cu, 3.3 g/t Au, 90 g/t Ag and 23% Zn. Blackwolf's drilling encountered broad intervals of disseminated and stringer sulphide mineralization, primarily pyrite which is suggestive of proximity to the mineralized horizon. Drill hole U21-225 intersected 2.66 meters averaging 0.11% Cu, 0.36 g/t Au, 13.47 g/t Ag and 1.34% Zn. Deeper hole U21-228 intersected a broader interval of 12.0 meters averaging 0.13% Cu, 0.45 g/t Au 5.0 g/t Ag and 0.25% Zn, including 2.0 meters averaging 0.62% Cu, 1.07 g/t Au, 11.4 g/t Ag and 0.52% Zn, with a second zone of sphalerite (zinc sulphide) stringers to the west of the Bluebell fault. Blackwolf is highly encouraged that the mineralization is continuing to depth, with these holes projected between 75 and 100 meters below the current mineral resource. The Company will perform additional follow-up drilling with down-hole geophysics to located where the wide trough of massive sulphide mineralization may project. Additional success will warrant extension of the underground ramp to permit drilling the Lookout Extension with shorter holes at a better orientation.

Niblack Project Upgrades
Blackwolf's Board of Directors has approved a plan to significantly upgrade the Niblack Camp and infrastructure, phasing out of the old barge camp. The new camp will allow significant more capacity for work crews to support the Company's vision for the Project. This work will include all-season Weatherhaven tents, new fuel storage, improved core handling and processing facilities and better underground equipment maintenance and water management. Located on tidewater, the Niblack facilities support an 800 meter-long, production-sized underground ramp that provides a platform for diamond grilling for exploration, resource expansion and upgrading.
