New Discovery Named "CGO East Waterfall" includes atypically high-grade PGEs

Tamarack, Minnesota--(Newsfile Corp. - May 22, 2024) - Talon Metals Corp. (TSX: TLO) (OTC Pink: TLOFF) ("Talon" or the "Company"), the majority owner and operator of the Tamarack Nickel-Copper-Cobalt Project ("Tamarack Nickel Project") in central Minnesota, proudly announces the discovery of a new high-grade mineralized area that has been named the "CGO East Waterfall". Because of its proximity to the Tamarack Resource, this new target area has been added to the Company's 2024 exploration plan, as additional discoveries could meaningfully impact the Tamarack Nickel Project's economics in the early years of a mine.

Highlights

• New Drill Hole 24TK0503 Intercepts High-Grade Massive Sulphide Mineralization: Intercepts 4.81 meters at 4.89% Ni, 4.10% Cu, 0,06% Co, with notably high Platinum Group Elements ("PGEs"), averaging 17.45 g/t Pd+Pt+Au (9.26% NiEq);
• Two Significant Intercepts in the Same Drill Hole: Drill Hole 24TK0503 has a second intercept of 79.22 meters at 0.80% NiEq;
• Near-Resource Expansion Potential: The "CGO East Waterfall" is approximately 120 meters below CGO East, representing low-hanging fruit for further exploration (see Figure 4);
• Analogous Waterfall Features: The CGO East Waterfall mirrors a previous discovery named the CGO West Waterfall (see Figure 3) in depth, grade, nickel tenor, and PGEs, highlighting true geological analogies across the Tamarack Resource Area;
• Next Steps for Exploration: Talon plans to use its borehole EM technology (geophysics) to gain deeper insights into the new CGO East Waterfall area, which will be followed up by additional drilling.

Brian Goldner, COO and Chief Exploration Officer of Talon, commented on today's results, stating: "What really excites me about this new high-grade intercept is that we could be in the early stages of discovering a large pool of massive sulphides. This pool could be the result of accumulation of sulphides from both the CGO East Waterfall and the CGO West Waterfall. This will certainly be further investigated with additional drilling in 2024."

Discovering the CGO West and East "Waterfalls"

During a 2021 drilling campaign, Talon discovered what has since been internally named the "CGO West Waterfall" (see Figure 3). This area is marked by a change in orientation from flat gently dipping basal massive sulphide mineralization ranging 1-2 meters in thickness to a vertically oriented massive sulphide unit with intervals of up to 14 meters, which resembles a waterfall. The waterfall also contains distinct differences in mineralization, and notably, an order of magnitude higher concentrations of PGEs than typically observed in the Tamarack Resource Area. This discovery represented a departure from the known characteristics of the CGO West area, as well as the highest nickel and copper grades assayed to date at the Tamarack Nickel Project.

The CGO East deposit, similar to CGO West, also has a gently dipping basal massive sulphide layer ranging from 1-4 meters in thickness; however, the potential for a waterfall had not been identified or known until new drill hole 24TK0503 (see Figure 4). This intercept of high-grade massive sulphide may be the down plunge extent of a waterfall (hence the name "CGO East Waterfall") and similar to the waterfall in the CGO West area. This intercept shows an order of magnitude increase in PGEs and nickel assays up to 10.5% Ni in individual samples (15.87% NiEq).

Through a combination of recent and historic drilling efforts, Talon's exploration team is understanding more about the potential origins of the Waterfall zones. A historic drill hole in the area (drill hole 10TK0127) revealed mixed massive sulphide and intrusion-hosted mineralization, including 6.27 meters of massive sulphide containing 4.5% NiEq. The recently drilled 24TK0503 is a 40-meter step out from this. These findings collectively point towards a consolidated body of massive sulphides as the likely origin of the Waterfall zones, offering a compelling theory for ongoing exploration and resource delineation efforts.

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).
