Talon Metals Confirms High-Grade Mineralization in the New Raptor Zone with Assays Grading up to 6.93% Nickel

Validates that the United States hosts additional high-grade nickel and progresses towards permitting for the underground mine and processing facility to supply Tesla

Tamarack, Minnesota--(Newsfile Corp. - April 19, 2023) - 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, confirms the presence of high-grade nickel in the newly discovered "Raptor Zone", with grades up to 6.93% nickel intersected.

Over the past several months, Talon has been advancing its dual strategy of (i) new exploration along the Tamarack Intrusive Complex, with the primary goal of discovering additional high-grade nickel-copper resources at the Tamarack Nickel Project; and (ii) progressing the requisite drilling, data collection, modelling, and engineering studies and designs to enable Talon to commence the environmental review process that starts the permitting process in the state of Minnesota and completing a feasibility study for the Tamarack Nickel Project. Talon is also progressing planning, design and permitting of its Battery Minerals Processing Facility in Mercer County, North Dakota, which was selected by the US Department of Energy for $114m in grant funding under the Bipartisan Infrastructure Law in October of 2022.

Talon CEO, Henri van Rooyen, commented: "Today's assay results further demonstrate that the United States has additional high-grade nickel growth potential in its mineral endowment. In 1997, the Department of the Interior and US Geological Survey predicted that there were high-grade nickel mineralization zones in the US that are similar to zones in Canada and Russia. They focused on the US Mid-Continental Rift (MCR), which extends from Kansas up through Michigan. Talon is singularly focused on exploring for additional high-grade nickel in the United States to help meet the goals set by Congress and President Biden for a domestic supply chain for electric vehicles and batteries from mining through to recycling."

Exploration Update: Confirmed High-Grade Nickel in the New Raptor Zone

Talon has received assay results for the newly drilled Raptor Zone, located nearly 2 miles (3.2 km) outside of the Tamarack Nickel Project's resource area. Talon believes it has confirmed a new "system" of high-grade nickel-copper mineralization within the Tamarack Intrusive Complex and consequently, is planning to drill an additional 20,000 meters within the Raptor Zone to determine if the 1-2 meters of identified high-grade massive nickel sulphide mineralization further thickens (similar to the Company's initial discovery within the CGO West area).

Assay results have been received for the 6 holes in the newly identified Raptor Zone that all intersected basal massive nickel mineralization (see Tables 1 and 2 below). These assays confirm that high-grade nickel mineralization exists well outside the Tamarack Nickel Project's resource area in the largely unexplored Raptor Zone.

*See Table 3 for further technical information

Brian Goldner, Chief Exploration and Operations Officer of Talon, said: "These assays confirm that the mineralization drilled in the Raptor Zone is high-grade and that there is exciting potential for additional discoveries within the Raptor Zone. To me, it's exciting that we have 1500 meters of prospective ground, bookended by intercepts of high-grade nickel mineralization, that has not yet been drilled. There is enough room in this undrilled portion of the Raptor Zone to fit more than 50 of the CGO West resource footprint (discovered by Talon in 2021). The Raptor Zone has all of the criteria needed for a top tier exploration target area - high grades, ample room and within just a few miles of the current Tamarack Nickel Project resource area. The primary objective of the Company's additional exploration efforts along the Tamarack Intrusive Complex is to enable Talon to identify future mineral resources to support the developing domestic battery manufacturing supply chain from mining through to recycling."

During the winter drilling program, Talon had 2 drill rigs (of a total of 8 drill rigs operating, as further discussed below) focused solely on exploration drilling. In addition to drilling within the new Raptor Zone, exploration drilling during the winter season has also focused on drilling various geophysical targets located within and outside of Tamarack Nickel Project's resource area. Drilling of these targets remains ongoing.

Exploration: Next Steps

With the completion of the Company's winter drilling program, the Company has plans for additional exploration drilling, with three to four drill rigs turning for the remainder of 2023. Exploration will focus on further drilling within the new Raptor Zone, with an additional 20,000 meters of drilling planned. In addition, the Company plans to drill between 3,000-5,000 meters in an area located approximately 1 km south of the Tamarack Nickel Project's resource area (currently referred to as the 164 Zone) where historic high-grade massive nickel sulphides have been identified but not yet followed up on.

Significant Progress Towards Feasibility Study, Environmental Review and Permitting in Minnesota

Winter Program (Production-related) Drilling Activities

Talon has had 8 drill rigs operating during the winter season in Minnesota, with 6 of these rigs dedicated to helping progress the Tamarack Nickel Project towards production.

Drilling and investigation activities have included, among other things, the following:

• 3 drill rigs conducting drilling activities for geotechnical characterization. This information will be used to inform the feasibility design of the surface and rail facilities.

• 1 vibrating sonic drill rig conducting overburden classification. This information will be used to do a feasibility design for the soil portion of the access tunnels to the underground mine.

• 1 truck rig conducting hydrophysical work for groundwater studies. This information will be used to supplement existing hydrogeological studies to inform feasibility design of water handling systems and water treatment.

• 1 diamond drill rig evaluating bedrock conditions for underground access and development. This information will be used to inform feasibility design of the rock portion of the access tunnel to the underground mine.

Environmental Review and Permitting

Talon has progressed studies and models to estimate potential environmental impacts that will form the basis for the Company's submission of documents for the State of Minnesota's environmental review process, inclusive of the Environmental Impact Statement (EIS), and to inform the feasibility study. More particularly, Talon has conducted data collection for the following:

• Groundwater studies (flow and quality);
• Surface water studies (flow and quality);
• Wetlands studies (flow and quality);
• Vegetation studies;
• Materials characterization studies (static and kinetic testing);
• Sound and vibration;
• Biological studies; and
• Archaeological reconnaissance survey and a historic architectural survey and assessment.

Talon also plans to further progress the following for the Tamarack Nickel Project:

• Evaluation of potential environmental resource impacts, including:
  • Air modelling;
  • Groundwater modelling;
  • Surface water and wetland modelling;
  • Geochemical modelling;
  • Multimedia assessment modelling;

• Visual impact analysis;
• Traffic study;
• Cultural surveys;
• Wetland delineation study; and
• Reports and plans to support the development of the Environmental Impact Statement and environmental permitting.

Talon continues to conduct quarterly community meetings to share information and listen to concerns from the community. At the most recent community meeting, Talon representatives shared information about the new Raptor Zone and provided an update in respect of Talon's ongoing exploration efforts. Talon has also been sharing information with proximate tribal sovereign governments, consistent with the Company's statement on tribal respect and engagement. The environmental review process provides extensive opportunity for public feedback and government-to-government consultation.

Engineering and Feasibility Study

Talon has completed significant engineering work for the underground mine and the surface facilities to inform the initial stages for Minnesota environmental review.

Talon believes that there is sufficient resource knowledge, geotechnical data, and environmental knowledge and data for Talon to continue to advance engineering work towards a feasibility study for the development of a mine and rail loadout facility at the Tamarack Nickel Project.

Environmental and regulatory considerations will be integrated during every step of the engineering design. The aim of early engagement and integration of environmental and regulatory considerations is to streamline the environmental review and permitting phase of the project.

Talon also intends to complete a similar package of initial engineering and environmental work for the Battery Minerals Processing Facility in North Dakota to support any applicable permitting reviews.
