Talon Metals Drilling Extends Thick Nickel-Copper Mineralization to the North-East of the Resource Area at the Tamarack Nickel Project

Road Town, Tortola, British Virgin Islands--(Newsfile Corp. - June 15, 2021) - Talon Metals Corp. (TSX: TLO) ("Talon" or the "Company") is pleased to provide an update on the Tamarack Nickel-Copper-Cobalt Project ("Tamarack Nickel Project"), located in Minnesota, USA. The Tamarack Nickel Project comprises the Tamarack North Project and the Tamarack South Project.

HIGHLIGHTS

• One of Talon's key catalysts for value creation in 2021 is to grow the Tamarack Nickel Project's current resource towards the north, while aiming to reduce the timeline to production.

• In April 2021, Talon announced that drill hole 20TK0277 (located in the northern portion of the resource area) intersected 138.18 meters (453.35 feet) grading 1.66% Ni, 1.02% Cu (2.26% NiEq¹) starting at 317.5 meters.

• As a follow-up to drill hole 20TK0277, Talon has just drilled new drill holes 21TK301 and 21TK0312, which represent, respectively, 49 and 25 meter north-east step-outs from drill hole 20TK0277.

• Talon is pleased to report that drill hole 21TK0301 successfully intersected an aggregate of 108.81 meters (356.9 feet) of nickel-copper mineralization in two intervals as follows:

• 43.58 meters (142.9 feet) of nickel-copper mineralization starting at 289.38 meters, and

• 65.23 meters (214.0 feet) of nickel-copper mineralization starting at 343.22 meters.

• Drill hole 21TK0312 also successfully intersected an aggregate of 87.35 meters (286.6 feet) of nickel-copper mineralization in three intervals as follows:

• 68.85 meters (225.9 feet) of nickel-copper mineralization starting at 309.49 meters;

• 4.34 meters (14.2 feet) of nickel-copper mineralization starting at 392.86 meters; and

• 14.16 (46.4 feet) of nickel-copper mineralization starting at 405.24 meters.

"The new drill holes announced today demonstrate that there will be further resource expansion within the area we refer to as the Upper Semi-Massive Sulphide Unit, located in the north-eastern portion of our resource area," said Etienne Dinel, Vice President - Geology, for Talon. "These new drill holes also demonstrate that we have not yet found the edge of the Upper Semi-Massive Sulphide Unit, especially considering the thickness of the mineralized intervals, and therefore, further drilling in this area is warranted."

SUMMARY

The new drilling reported in today's press release should be viewed in the context of historic drill hole 09TK0094² and Talon's recent drill hole 20TK0277. Drill hole 20TK0277 intersected 138.18 meters (453.35 feet) of disseminated and semi-massive sulphide mineralization, grading 1.66% Ni, 1.02% Cu, 0.04% Co, 0.21 g/t Pd, 0.36 g/t Pt, and 0.21 g/t Au (2.26% NiEq or 6.03% CuEq³) starting at 317.5 meters, and extended the Upper Semi-Massive Sulphide Unit (the "Upper SMSU") further north and east (see the Company's press release dated April 13, 2021).

Historic drill hole 09TK0094 intersected the Upper SMSU mineralization with 27 meters grading 0.83% Ni, 0.57% Cu, 0.03% Co, 0.06 g/t Pd, 0.10 g/t Pt and 0.09 g/t Au (1.13% NiEq or 3.02% CuEq) starting 349.5 meters and an additional 7.5 meters of 0.69% Ni, 0.42% Cu, 0.02% Co, 0.07 g/t Pd, 0.11 g/t Pd and 0.06 g/t Au (0.92% NiEq or 2.47% CuEq) starting at 397.5 meters.

Talon followed the success of drill hole 21TK0277 with three additional drill holes designed to probe further east and north in an effort to further expand the Upper SMSU. Drill holes 21TK0301 and 21TK0312 are, respectively, 25 and 45 meter step-outs south of drill hole 09TK0094, while drill hole 21TK0315 represents a 25 meter step-out north of drill hole 09TK0094.

Results from the three new drill holes are as follows:

• Drill hole 21TK0301 intersected an aggregate of 108.81 meters (356.9 feet) of nickel-copper mineralization in two intervals, with:

• 43.58 meters (142.9 feet) of nickel-copper mineralization starting at 289.38 meters, and

• 65.23 meters (214.0 feet) of nickel-copper mineralization starting at 343.22 meters.

• Drill hole 21TK0312 intersected an aggregate of 87.35 meters (286.6 feet) of nickel-copper mineralization in three intervals, with:

• 68.85 meters (225.9 feet) of nickel-copper mineralization starting at 309.49 meters;

• 4.34 meters (14.2 feet) of nickel-copper mineralization starting at 392.86 meters; and

• 14.16 (46.4 feet) of nickel-copper mineralization starting at 405.24 meters.

• Drill hole 21TK0315 intersected 51.6 meters (169.2 feet) of nickel-copper mineralization starting at 284.2 meters.

• Assays are pending for all of the above-noted drill holes.

With the intention of advancing the project towards a further resource and economic update, Talon will continue drilling this area with a series of infill drill holes, as well as drill holes with the goal of identifying the edge of the Upper SMSU. To date, the drilling shows growth of the mineralization to the north-east, while the edge of the mineralization within the Upper SMSU has not yet been defined.

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).
