Talon reports assays from eight (8) new drill holes in the CGO East area, located outside of the Tamarack Nickel Project's main resource area.
These new assays demonstrate high nickel and copper grades across a large area in the CGO East area with these holes testing an area approximately 700 meters long (north-south).
The assays also demonstrate significant thickness of the mineralized intervals. Notable assay results include:
Drill hole 22TK0390 intersected 6.56 meters of nickel-copper mineralization grading 2.95% Ni, 1.01% Cu (3.59% NiEq or 9.56% CuEq) starting at a depth of 133.60 meters;
Includes 2.53 meters of 3.77% Ni, 1.54% Cu (4.66% NiEq or 12.44% CuEq) starting at a depth of 137.7 meters.
Drill hole 21TK0358 intersected 21.92 meters of nickel-copper mineralization grading 1.25% Ni, 0.61% Cu (1.64% NiEq or 4.36% CuEq) starting at a depth of 245.3 meters;
Includes 2.93 meters of 5.65% Ni, 2.04% Cu (6.88% NiEq or 18.36 CuEq) starting at a depth of 264.3 meters.
Drill hole 21TK0393 intersected 33.72 meters of nickel-copper mineralization grading 0.94% Ni, 0.66% Cu (1.37% NiEq or 3.64% CuEq) starting at a depth of 120 meters; and
Drill hole 21TK0395 intersected 31.1 meters of nickel-copper mineralization grading 0.82% Ni, 0.51% Cu (1.15% NiEq or 3.08% CuEq) starting at a depth of 118.3 meters.
Notably, the assays contained in today's news release demonstrate consistent high nickel and copper grades in the CGO East area. Previous assays from CGO East were reported in a news release issued on October 5, 2021, as follows:
Drill hole 21TK0305 intersected 17.95 meters of nickel-copper mineralization grading 0.7% Ni, 0.44% Cu (0.96% NiEq or 2.55% CuEq) starting at a depth of 199.5 meters;
Drill hole 21TK0306 intersected 15.94 meters of nickel-copper mineralization grading 0.77% Ni, 0.41% Cu (1.09% NiEq or 2.9% CuEq) starting at a depth of 240.3 meters;
Drill hole 21TK0309 intersected 2.58 meters of mixed and massive nickel-copper mineralization grading 4.26% Ni, 1.89% Cu (5.25% NiEq or 13.99% CuEq) starting at a depth of only 248.18 meters; and
Drill hole 21TK0311 intersected 4.35 meters of mixed and massive nickel-copper mineralization grading 3.50% Ni, 1.40% Cu (4.38% NiEq, 11.68% CuEq) starting at a depth of 234.5 meters.
"We are extremely pleased with the assay results announced today from the CGO East area, which represents one of the newly discovered mineralized areas outside of the Tamarack Nickel Project's defined resource area," said Brian Goldner, Chief Exploration and Operations Officer. "This new drilling has demonstrated over 600 meters of continuous high-grade nickel copper sulphide mineralization, with potential to extend an additional 200 meters to the north."
Goldner continued: "By way of general exploration update, the Company has now completed its infill drilling program, and has already deployed a drill rig well outside of the Tamarack Nickel Project's defined resource area with the goal of trying to make a new discovery along the Tamarack Intrusive Complex."
The CGO East target area is large, stretching over an area of 500 meters (east-west) by 900 meters (north-south) outside of the Tamarack Nickel Project's resource area. Drilling has confirmed this area hosts wide sheets of shallow mineralization consistent with the previously reported drill hole results. The mineralized zone in the CGO East area typically begins with a thick sheet of disseminated sulphide mineralization above a sheet of high-grade mixed and massive sulphide mineralization at the base of the intrusion.
The mixed and massive sulphide sheet of mineralization at the base of the intrusion contains high nickel and copper grades across a large area. The overlying sheet of disseminated nickel and copper mineralization is lower grade as expected, but still contains thick zones of >1% nickel across a large area in drill holes 21TK0289, 21TK0290, 21TK0291, 21TK0296, 21TK0304, 21TK0309, 21TK0311 (see the Company's press release dated October 5, 2021) and 21TK0358.
These new assays results, combined with results of historical drill holes in the CGO East area, confirm a continuous strike length of high-grade nickel-copper mineralization for over 600 meters long in the north-south direction. The width of mineralization varies between 40 meters to 80 meters in some locations (see Figure 2). Importantly, the thickness of both layers of mineralization continues to be persistent at up to 33 meters, as the mineralization shallows to a depth of about 120 meters and may extend further (shallower) to the north. The extent and thickness of nickel-copper mineralization in the CGO East area demonstrates the potential to add volume to the current resource estimate at the Tamarack Nickel Project in an area that is accessible to underground mining.
From south to north drill holes 20TK0271 to 22TK0393 demonstrate over 600 meters of continuous high-grade nickel-copper sulphide mineralization with the potential to extend an additional 200 meters to the north (see Figure 2).
The central portion of the CGO East area appears to be a good indication of the potential width of the combined sheets of mineralization:
- Drill hole 21TK0304 intersected 11.59 meters of 1.31% Ni, 0.85% Cu, 0.03% Co, 0.19 g/t Pd, 0.40g/t Pt, 0.29g/t Au (1.87% NiEq or 4.98% CuEq) starting at 237 meters; and
- Drill hole 21TK0305 intersected 17.95 meters of 0.7% Ni, 0.44% Cu, 0.02% Co, 0.05g/t Pd, 0.12g/t Pt and 0.12g/t Au (0.96% NiEq or 2.55% CuEq) starting 191.85 meters.
In addition, two drill holes discussed in this press release were targeting a lateral step-out to CGO east and both holes intersected high-grade nickel-copper mineralization, and demonstrate that the overall width has increased to 50 meters:
- Drill hole 22TK0391 intersected 10.6 meters of 1.05% Ni, 0.57% Cu, 0.03% Co, 0.08 g/t Pd, 0.17g/t Pt, 0.29.16g/t Au (1.40% NiEq or 3.74% CuEq) starting at 198.69 meters; and
- Drill Hole 22TK0394 intersected 10.09 meters of 1.12% Ni, 0.51% Cu, 0.04% Co, 0.07g/t Pd, 0.11g/t Pt and 0.12g/t Au (1.43% NiEq or 3.81% CuEq) starting 205.16 meters
The distance from drill holes 21TK0304 to 21TK0305 is 70 to 80 meters and is currently the widest extent of mineralization (east to west) defined in the CGO East area.
The sheet of high-grade nickel-copper mixed and massive sulphide has been mapped with in-house surface EM (geophysics) and each borehole has been surveyed with borehole electromagnetic (BHEM) equipment (geophysics) operated by Talon. The drilling results combined with the newly reported assays continue to demonstrate the effectiveness of this exploration strategy for finding and then tracing high-grade mineralization across the Tamarack Intrusive Complex.

Talon is a TSX-listed base metals company in a joint venture with Rio Tinto on the high-grade Tamarack Nickel-Copper-Cobalt Project located in central Minnesota. Talon's shares are also traded in the US over the OTC market under the symbol TLOFF. The Tamarack Nickel Project comprises a large land position (18km of strike length) with high-grade intercepts outside the current resource area. Talon has an earn-in right to acquire up to 60% of the Tamarack Nickel Project, and currently owns 51%. Talon is focused on (i) expanding and infilling its current high-grade nickel mineralization resource prepared in accordance with NI 43-101 to shape a mine plan for submission to Minnesota regulators, (ii) following up on additional high-grade nickel mineralization in the Tamarack Intrusive Complex, and (iii) exploring the prospects for significant carbon storage in the ultra-mafic rocks that comprise the Tamarack Intrusive Complex through carbon mineralization. Talon has an agreement with Tesla Inc. to supply it with 75,000 metric tonnes (165 million lbs) of nickel in concentrate (and certain by-products, including cobalt and iron) from the Tamarack Nickel Project over an estimated six-year period once commercial production is achieved.

All samples were analysed by ALS Minerals. Nickel, copper, and cobalt grades were first analysed by a 4-acid digestion and ICP AES (ME-MS61). Grades reporting greater than 0.25% Ni and/or 0.1% Cu, using ME-MS61, trigger a sodium peroxide fusion with ICP-AES finish (ICP81). Platinum, palladium and gold are initially analyzed by a 50g fire assay with an ICP-MS finish (PGM-MS24). Any samples reporting >1g/t Pt or Pd trigger an over-limit analysis by ICP-AES finish (PGM-ICP27) and any samples reporting >1g/t Au trigger an over-limit analysis by AAS (Au-AA26).
