Road Town, Tortola, British Virgin Islands (July 8, 2020) – Talon Metals Corp. (“Talon” or the “Company”) (TSX:TLO) is pleased to provide an update on the Tamarack Nickel-Copper-Cobalt project (“Tamarack Project”), located in Minnesota, USA. The Tamarack Project comprises the Tamarack North Project and the Tamarack South Project.

Highlights

• The Company’s Updated Preliminary Economic Assessment (“PEA”) (with an effective date of March 12, 2020)¹ included only 9 million tonnes of material in the proposed mine plan. More specifically, 3.1 million tonnes of material were excluded from the Company’s proposed mine plan, as development of a representative flowsheet was still in progress by the Company.
• Since March 12, 2020, flotation optimization has been conducted on a composite sample grading 1.61% Ni and 0.96% Cu. This is considered representative of the mineralization at the Tamarack
• The flowsheet development has been successful: Flotation selectivity was unaffected by the addition of the material representative of the remaining 3.1 million tonnes of
• An updated mine plan and economic analysis is now underway by the Company to reflect the positive results from the metallurgical test
• The Company is presently conducting a Locked Cycle Test with the intention of using the concentrates to commence downstream flowsheet development with the goal of establishing an integrated nickel sulphate complex at the Tamarack Project. Such a complex is expected to be strategic to US and European electric vehicle
• Based upon the Company’s recent metallurgical test results, the Company is optimistic that the large body of mineralization above the high-grade massive sulphide unit (the 138 Zone) can be included in future mine

“The metallurgical performance of the Tamarack mineralization continues to excite”, said Oliver Peters, Talon’s metallurgical consultant. “A simplified flowsheet has now been developed to treat the entire resource from the Tamarack Project. Results are excellent and most certainly better than expected. We will now commence hydrometallurgical flowsheet development with the goal of producing nickel sulphates in the United States. The ultimate goal is to create a nickel sulphate complex at Tamarack that will be one of the lowest cost producers globally.”

“In May 2019, at the Benchmark Minerals Summit in Washington D.C. (Securing 21st Century

U.S. Supply Chains for EVs and Energy Storage), the Company presented a vision to collapsing the value chain for producing nickel sulphates or precursor, which are key inputs into lithium-ion batteries used in electric vehicles and renewable energy storage: We are rapidly moving towards the realization of this vision”, said Henri van Rooyen, Talon CEO.

Technical Discussion

Selection of Life-of-Mine Composite

In late 2019, two flotation composites were generated to determine the impact of including the 138 Zone in the life-of-mine mill feed (see Figure 1). The two composites comprised a life-of- mine composite with the SMSU/MSU mineralization (semi-massive sulphide unit and massive sulphide unit mineralization) and the 138 Zone (total of 8.02 million tonnes of material) and a life- of-mine composite without the 138 Zone (total of only 5.32 million tonnes of material). A total of 475 drill hole intervals were selected with careful consideration of grade and spatial distribution to produce representative resource composites.

A series of rougher and cleaner flotation tests were completed on the two composites and the results were analyzed to determine if the 138 Zone had a detrimental impact on the flotation response of the SMSU and MSU mineralization.

While the rougher recovery for the 138 Zone mineralization of 80.4% Ni and 79.2% Cu was lower compared to the SMSU/MSU mineralization at 92.2% Ni and 94.8% Cu, the inclusion of the 138 Zone material did not result in an increased entrainment of gangue minerals. Hence, a decision was made to proceed with the process optimization program including the 138 Zone since it maximizes mineable metal units.

Process Optimization

The life-of-mine with 138 Zone composite was subjected to a process optimization program to produce separate Ni and Cu concentrates. The program culminated in a simple flowsheet consisting of a bulk rougher, two stages of bulk cleaning, a regrind, and a three-stage Cu/Ni separation circuit.

An open-circuit cleaner flotation test produced a Ni concentrate grading 10.2% Ni and 1.08% Cu and a Cu concentrate grading 30.1% Cu and 0.84% Ni. Both concentrates produced grades that are attractive for pyrometallurgical processing in Ni and Cu smelters, respectively.

The open-circuit Cu and Ni recovery into the Cu/Ni separation circuit was high at 84.4% for Cu and 80.0% for Ni. These values are expected to increase further during closed-circuit operation since circulating streams are treated as tailings in open-circuit tests.

Next Steps

A locked cycle flotation test is scheduled to be completed to simulate the closed-circuit performance of the proposed flowsheet and to produce approximately 3 kg of Ni concentrate for hydrometallurgical flowsheet development. Additional process optimization is planned for the next phase of flotation testing to evaluate flowsheet modifications that further improve concentrate grades and/or metal recoveries.

Drilling Update

With limited additional costs, Talon drilled the edges of the 138 Zone during the January to March 2020 exploration program. The 138 Zone is a large body of mineralization above the high-grade massive sulphide unit. The results, listed below, are in line with the Company’s resource model:

• Drill hole 12TK0153C intersected 33 meters (108.3 feet) of disseminated sulphides grading 0.58% Ni, 0.43% Cu, 0.02% Co, 0.06 g/t Pd, 0.11 g/t Pt and 0.08 g/t Au (0.83% NiEq² or 2.21% CuEq³), starting at 426 meters (see Figure 1 and Tables 1 and 2);
• Drill hole 12TK0153A intersected 46.88 meters (153.8 feet) of disseminated sulphides grading 0.58% Ni, 0.38% Cu, 0.02% Co, 0.06 g/t Pd, 0.11 g/t Pt and 0.09 g/t Au (0.81% NiEq or 2.15% CuEq), starting at 424.12 meters (see Figure 1 and Tables 1 and 2);
• Drill hole 20TK0265 intersected 60 meters (196.85 feet) of disseminated sulphides grading 0.58% Ni, 0.38% Cu, 0.02% Co, 0.07 g/t Pd, 0.11 g/t Pt and 0.07 g/t Au (0.80% NiEq or 2.12% CuEq), starting at 422 meters (see Figure 1 and Tables 1 and 2).
• Drill Hole 12TK0153B intersected 28 meters (91.9 feet) of disseminated sulphides grading 58% Ni, 0.39%Cu, 0.02% Co, 0.06 g/t Pd, 0.10 g/t Pt and 0.08 g/t Au (0.80% NiEq or 2.15% CuEq), starting at 426 meters (see Figure 1 and Tables 1 and 2).

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).
