US Battery Supply Chain: Talon Metals Announces Significant Increase to Mineral Resource Estimate at Tamarack Nickel Project

Talon Doubles Indicated Resource Tonnage, including 570% Increase in High-Grade Nickel

This news release constitutes a "designated news release" for the purposes of the Company's prospectus supplement dated December 16, 2021 to its short form base shelf prospectus dated December 7, 2021

Tamarack, October 19, 2022 - Talon Metals Corp. (TSX: TLO) (OTC Pink: TLOFF) ("Talon" or the "Company") has updated its mineral resource estimate for the Tamarack Nickel Project located in central Minnesota.

The total indicated mineral resource estimate now stands at approximately 8.56 million tonnes grading 1.73% nickel plus by-products (2.34% NiEq) containing 148,000 tonnes of nickel (see Tables 1 and 2 below). This represents a 98% increase in the amount of contained nickel (in the indicated category) compared to the Company's previous indicated mineral resource estimate ("PEA #3")¹. The total inferred resource estimate, which is in addition to the total indicated mineral resource, is now at approximately 8.46 million tonnes grading 0.83% nickel plus by-products (1.19% NiEq) containing 70,000 tonnes of nickel (see Tables 1 and 2 below).

The high-grade Massive Sulphide (MSU) or Mixed Massive Sulphide (MMS) now stands at 1.05 million tonnes grading 4.53% nickel plus by-products (5.76% NiEq) (in the indicated category) (see Table 3 below), containing 47,000 tonnes of nickel. This represents a 570% increase in the amount of contained nickel (MSU/MMS) compared to PEA #3.

The mineral resource update also sets out the estimated amount of recoverable iron (Fe in sulphides) given this is a payable by-product under the Tesla-Talon agreement entered into on January 7, 2022 ("Tesla-Talon Supply Agreement") (see Table 1 below). Nonetheless, to be conservative, the Company has excluded the iron (Fe in sulphides) from its calculation of nickel equivalent (NiEq).

A significant portion of the increase in the Company's updated mineral resource estimate is attributable to Talon's recent discoveries and exploration success in the shallow, high-grade CGO East and CGO West exploration areas. Drilling outside of the updated mineral resource area is already underway, as Talon continues to work to further expand the mineral resource.

"During the successful discovery and delineation of the high-grade nickel CGO East and CGO West ore bodies, our team of drillers, geophysicists, geologists, engineers and environmental scientists developed a proprietary, Advanced Exploration System (AES), which is a unique combination of equipment and methods for deployment along the 11-mile Tamarack Intrusive Complex and in Michigan," said Henri van Rooyen, CEO of Talon Metals. "The 11-mile Tamarack Intrusive Complex and Michigan represent extremely prospective and underexplored high-grade nickel districts, primarily due to a lack of the consistent deployment of tailor-made mineral exploration technologies. The AES is to US Midcontinent Rift nickel discovery and delineation what Tesla is to EV: A revolution in successful innovation and deployment."

Todd Malan, Chief External Affairs Officer and Head of Climate Strategy at Talon, commented: "The upgraded resource at the Tamarack Nickel Project combined with our acquisition of mineral rights in the Upper Peninsula of Michigan and our partnership with Fleet Technologies to use their satellite technology to expedite the discovery of more high-grade nickel in the Lake Superior region are all part of Talon's strategy to become a domestic supplier of nickel and other critical ingredients to the US battery supply chain." Malan continued: "Selection of our Battery Minerals Processing Facility for $114.8 million in funding from the Bipartisan Infrastructure Law (BIL) by the Department of Energy is a strong signal that the United States intends to harness its own mineral resources like the nickel, iron, cobalt and copper in the Lake Superior region to become 'mineral independent'. There is a clear bipartisan consensus that we must end America's dependence on China, Russia and other foreign sources for the raw materials required in the energy transition that is required to address climate change. Responsible domestic mining and battery recycling are the solution."

Notes:

• All resources are in situ and reported at a 0.50% Ni cut-off
• Mining recovery and dilution factors have not been applied to the estimates
• NiEq based on metal prices in U.S. dollars of $9.50/lb Ni, $3.75/lb Cu, $25.00/lb Co, $1,000/oz Pt, $1,000/oz Pd and $1,400/oz Au

Talon will file an updated technical report prepared in accordance with National Instrument 43-101 ("NI 43-101"), which will include the material increases to the mineral resource estimate within 45 days. In addition, once a location for the Battery Minerals Processing Facility in North Dakota has been finalized (see the Company's press release dated October 19, 2022) and inputs, operating costs and construction estimates have been determined, Talon plans to update the economic parameters, including cut-off grade, in respect of the Tamarack Nickel Project.

Significant Increase in Mineral Resource at the Tamarack Nickel Project

The updated and significantly increased independent mineral resource estimate is largely the result of Talon's successful 2021-2022 development and deployment of Talon's Advanced Exploration System ("AES") that enables Talon to rapidly conduct in-house exploration programs at the Tamarack Nickel Project. Talon's AES resulted in two new high-grade nickel-copper discoveries, known as the high-grade CGO East and CGO West areas. These newly discovered mineralized zones lie north of the Company's previous mineral resource area (see Figure 1 for areas of significant nickel-copper mineralization). The shallow, high-grade mineralization found within the CGO East and CGO West areas not only provide for growth in the size of the mineral resource (and ultimately resulted in the Tesla-Talon Supply Agreement) but is also expected to result in an accelerated development pathway for an underground mine.

Talon's AES consists of a unified set of technologies assembled and operated safely and in an environmentally responsible manner by the Company's in-house team of drillers, geophysicists, geologists, engineers and environmental scientists. It is the synergy of Talon's interdisciplinary teams and technologies - from multiple surface detection methods that can cover large areas, to rapidly drilling anomalies, conducting downhole surveys, assessing drilled core, and then leveraging the combined data within days instead of months to plot the next drillholes - that makes Talon's AES extremely efficient at identifying nickel deposits with strong prospects for economic extraction.

Talon's AES is presently deployed to the north of the present mineral resource area, with a plan for drilling to the south of the mineral resource area during the winter period. Additionally, Talon is preparing for deployment of its AES in Michigan. Talon's Michigan roll-out will consist of the use of new and innovative surface geophysical techniques on the back of the Company's geological team's unique understanding of prospective, high-grade nickel targets. Additionally, the Company's expanded drilling capabilities will be utilized to rapidly drill pre-identified targets as well as new targets followed by the use of cross-hole seismic and selective borehole electromagnetic surveys (geophysics).

Through this well-planned deployment of Talon's unique AES, Talon is poised to become the US solution to onshoring nickel concentrate production for a US battery nickel and battery iron supply chain that will be leading in effectiveness, cost and environmental responsibility.

Table 3: Tamarack North Project Updated 2022 Mineral Resource Estimate (Effective Date: October 10, 2022)

Notes:

• All mineral resources are in situ and reported at a 0.50% Ni cut-off
• Tonnage estimates are rounded down to the nearest 1,000 tonnes and totals may not add up due to rounding
• Fe% in sulphides is based on sulphur concentration associated with sulphide minerals and a calculation of stoichiometric Fe concentration in Pentlandite and Pyrrhotite
• Mining recovery and dilution factors have not been applied to the estimates
• NiEq grade based on metal prices in U.S. dollars of $9.50/lb Ni, $3.75/lb Cu, $25.00/lb Co, $1,000/oz Pt, $1,000/oz Pd and $1,400/oz Au using the following formula: NiEq% = Ni%+ Cu% x $3.75/$9.50 + Co% x $25.00/$9.50 + Pt[g/t]/31.103 x $1,000/$9.50/22.04 + Pd[g/t]/31.103 x $1,000/$9.50/22.04 + Au[g/t]/31.103 x $1,400/$9.50/22.04. Fe is not included in the NiEq calculation
• No adjustments were made for recovery or payability

The updated mineral resources are derived from a Datamine constructed block model with a block size of 5m x 5m x 5m for the Lower and Upper Semi-Massive Sulphide Unit ("LSMSU" and "USMSU") and the 138 Mixed Zone ("138 Zone"), and a block size of 2.5m x 2.5m x 2.5m for the Massive Sulphide Unit ("MSU"), and the Coarse Grained Peridotite domains ("CGO West" and "CGO East").

All Domains utilized the Datamine RM^® "unfold" process and had top cuts applied to restrict outlier assay values (Ni, Cu, Co, Pt, Pd and/or Au). The eight domains utilized either Ordinary Kriged or Inverse Distance methodology to interpolate grades (Nickel ("Ni"), Copper ("Cu"), Cobalt ("Co"), Platinum ("Pt"), Palladium ("Pd") and Gold ("Au") from either 1.0 or 1.5 meter composited drill holes. Density estimates were based on specific gravity measurements and where absent, regression formulas were applied.

The mineral resources reported are based on a "blocks above a 0.5% Ni cut-off" basis and were then examined visually by Golder and found to have reasonable continuity suitable for underground selective and bulk mining methods. The proportion of Fe in sulphides was calculated stoichiometrically from Pyrrhotite and Pentlandite, using some basic mineralogical assumptions.
