High levels of platinum group metals present, which is a key input for multiple clean energy systems

Tamarack, Minnesota--(Newsfile Corp. - August 21, 2023) - Talon Metals Corp. (TSX: TLO) ("Talon" or the "Company") has successfully drilled 101.71 meters (333 feet) of high-grade nickel-copper mineralization at the Tamarack Nickel Project, grading 1.94% Ni,1.84% Cu, 0.35 g/t Pd, 0.64 g/t Pt and 0.62 g/t Au (1.61 g/t PGEt + Au) (3.04% NiEq) (see Table 1).

Highlights

• Drill intercept of 101.71 meters grading 1.94% Ni, 1.84% Cu and 0.35 g/t Pd, 0.64 g/t Pt and 0.62 g/t Au (1.61 g/t PGEt + Au) (3.04% NiEq);

• Drill hole was completed in partnership with a research team from Columbia University that is funded by the Department of Energy (DOE) Advanced Research Projects Agency-Energy (ARPA-E) Mining Innovations for Negative Emissions Resource Recovery (MINER) program that funds novel approaches to enhanced metal recoveries within the mining industry (see Columbia University | arpa-e.energy.gov).

• A team from Columbia University has partnered with Talon to use critical mineral concentrates from the Tamarack Nickel Project to conduct lab studies that will explore potential novel processing technologies that lower the CO₂ footprint of mining operations, while increasing the amount of nickel and copper extracted from ore (beyond the high metallurgical recoveries already achievable at the Tamarack Nickel Project). These R&D programs aim to increase US nickel production and lower the overall cost of nickel extraction compared to standard industry practices.

• Using funds from Columbia's ARPA-E grant, Talon successfully drilled 101.71 meters (333 feet) of high-grade nickel-copper mineralization (3.04% NiEq) at the Tamarack Nickel Project. This drill hole is located within the Tamarack Resource Area (see Figure 2).

• The drill hole was part of Talon's approved annual drill program with the Minnesota Department of Natural Resources (an approval process that includes input from proximate tribal sovereign governments).

• Talon and the State of Minnesota gain additional geological knowledge with respect to the Tamarack Nickel Project through the Columbia funded drilling, while Columbia will obtain material to utilize in their lab experiments to test novel approaches to enhanced metal recoveries within the mining industry.

• The combination of Columbia University's initiatives, along with Talon's ongoing exploration and innovation programs, are part of Talon's "full value mining" strategy to ensure that society is able to utilize the maximum amount of critical minerals in the ore that is extracted.

"Intercepting 101.71 meters (333 feet) of high-grade nickel-copper mineralization is a reminder of the uniqueness of the Tamarack Nickel Project's US nickel resources," said Henri van Rooyen, CEO of Talon. "Most projects aspire to intercept just 2 meters (6.6 feet) of high-grade nickel. The goal of this Columbia collaboration is to both add to our understanding of the ore body, while also supporting research aimed at recovering additional nickel, copper and other critical minerals used in clean energy systems."

"One exciting aspect of this drill hole is that the copper and PGE grades are much higher than anticipated compared to the nickel grades, especially in the lower zone of mineralization where 12.4 meters assayed at 2.98% Ni, 3.84% Cu, 1.38 g/t Pd, 2.79 g/t Pt, and 2.68 g/t Au (6.85 g/t PGEt+Au)," said Brian Goldner, Chief Exploration Officer and Chief Operating Officer at Talon. "The exploration team is working to model this unusual area of fractionated mineralization to identify other areas within the resource it may be residing."

Alan West, Professor of Chemical Engineering in Columbia's School of Engineering and Applied Sciences, and the project's Principal Investigator, remarked: "The Columbia Engineering team is very excited to partner with Talon and ARPA-e. This is a great opportunity to demonstrate and scale our processes aimed at improving the recovery of the critical materials that we need to transition energy systems and manufacturing to sustainable technologies, while also minimizing local environmental impacts of metals production."

Talon's CEO, Henri van Rooyen concluded: "Talon is taking a "full value mining" approach and harnessing innovation to understand how we can do mineral extraction in a better way. By working with top-notch US research and development institutions like Columbia University, we are hoping to deliver better outcomes that help the United States create secure domestic supplies of critical minerals for clean energy systems."

Quality Assurance, Quality Control and Qualified Persons

Please see the technical report entitled "November 2022 National Instrument 43-101 Technical Report of the Tamarack North Project - Tamarack, Minnesota" with an effective date of November 2, 2022 ("November 2022 Technical Report") prepared by independent "Qualified Persons" (as that term is defined in National Instrument 43-101 ("NI 43-101")) Brian Thomas (P. Geo), Roger Jackson (P. Geo), Oliver Peters (P. Eng) and Christine Pint (P.G) for information on the QA/QC, data verification, analytical and testing procedures at the Tamarack Nickel Project. Copies are available on the Company's website (www.talonmetals.com) or on SEDAR at (www.sedar.com). The laboratory used is ALS Minerals who is independent of the Company.

Lengths are drill intersections and not necessarily true widths. True widths cannot be consistently calculated for comparison purposes between holes because of the irregular shapes of the mineralized zones. Drill intersections have been independently selected by Talon. Drill composites have been independently calculated by Talon. The geological interpretations in this news release are solely those of the Company. The locations and distances highlighted on all maps in this news release are approximate.

Dr. Etienne Dinel, Vice President, Geology of Talon, is a Qualified Person within the meaning of NI 43-101.

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).
