HIGHLIGHTS

• Talon reports assays from thirteen (13) 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 430 meters long (north-south).

• The assays also demonstrate significant thickness of the mineralized intervals and are expected to add meaningful volume to future resource estimates.

• Some of the notable assay results, include:

  • Drill hole 21TK0305 intersected 17.95 meters of nickel-copper mineralization grading 0.7% Ni, 0.44% Cu (0.96% NiEq¹ or 2.55% CuEq²) starting at only 199.5 meters depth;

  • 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 only 240.3 meters depth;

  • 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 only 248.18 meters depth; 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 only 234.5 meters depth.

"We are extremely pleased with the assay results announced today from the CGO East area, which sits outside of the Tamarack Nickel Project's defined resource area," said Brian Goldner, Vice President of Exploration. "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. The extent and thickness of high-grade nickel-copper mineralization in the CGO East area has the potential to add significant volume to the current resource estimate at the Tamarack Nickel Project."

SUMMARY

CGO East

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 confirms 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 assay results from the new drill holes reported in this press release (see Table 2) confirm the two layers of mineralization have grades of nickel and copper that can be included in future resource estimates. 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, and 21TK0311.

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 combined range from 6 meters to 31 meters. The extent and thickness of nickel-copper mineralization in the CGO East area demonstrates the potential to add significant 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 21TK0295 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.

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 imaged with Bore Hole Electromagnetic (BHEM) surveying completed by Talon on each drill hole in the CGO East area. The drilling results combined with the newly reported assays continue to demonstrate the effectiveness of this exploration strategy for finding and then tracing new mixed and massive high-grade mineralization across the Tamarack Intrusive Complex.

CGO Bend

The CGO Bend area is a zone that lies between the CGO East and CGO West areas that is composed of low-grade mineralization within the Coarse-Grained Olivine ("CGO") intrusion. Talon has previously reported six holes drilled in this area that intersected up to 42 meters of disseminated nickel-copper mineralization (see the Company's press release dated June 1, 2021).

Newly received assays from drill hole 21TK0284 continue to show the presence of low-grade nickel and copper mineralization characteristic of the CGO Bend area (see Table 2).

Length refers to drill hole length and not True Width.
True Width is unknown at the time of publication.
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).
