Talon Metals Discovers Thick Pool of Massive Nickel-Copper Mineralization Outside of the Resource Area: 13.88 Meters (45.5 Feet) Starting at Only 225 Meters

Road Town, Tortola, British Virgin Islands--(Newsfile Corp. - May 19, 2021) - Talon Metals Corp. (TSX: TLO) ("Talon" or the "Company") is pleased to provide an update on the Tamarack Nickel-Copper-Cobalt Project ("Tamarack Nickel Project"), located in Minnesota, USA. The Tamarack Nickel Project comprises the Tamarack North Project and the Tamarack South Project.

HIGHLIGHTS

• Talon has been rapidly drilling in a target area that starts approximately 100 meters north-north-east of the Tamarack Nickel Project's resource area (i.e., outside of the resource area) and extends for an additional 400 meters. The target area is referred to as "CGO West".

• To date, with very limited drilling, the CGO West area has been characterized by 1 to 5 meter intercepts of massive nickel-copper mineralization, with up to 27 meters of disseminated mineralization overlying the massive mineralization.

• New drill hole 21TK0313 has intersected 13.88 meters (45.5 feet) of mixed massive nickel-copper mineralization starting at a shallow depth of only 225 meters, with assays pending.

• This is the thickest intercept to date within the CGO West area;

• This thick intercept was unexpected for this area, as the surrounding holes have patterned sheet-like mineralization up to 5 meters thick;

• This intercept could potentially indicate a pool of sulphides; and

• As a follow-up, the Company is actively running geophysics to guide future drilling.

• In addition to this new massive nickel-copper intercept, the Company has also successfully intersected within the CGO West area:

• 27.2 meters (89.2 feet) meters of nickel-copper mineralization starting at only 135.25 meters, assays pending (drill hole 21TK0298); and

• 9.3 meters (30.5 feet) meters of nickel-copper mineralization starting at only 142.65 meters, including 1.85 meters (6.1 feet) of mixed massive nickel-copper mineralization at 150.1 meters (drill hole 21TK0299), assays pending.

• The results from these holes, coupled with mineralization from the previously reported holes nearby, indicate that mineralization is extensive in the CGO West area and may have a similar geometry to the CGO East area.

"Intersecting almost 14 meters of massive sulphide in a zone that lies outside of our resource area is clearly a new discovery," said, Dr. Etienne Dinel, Head of Geology. "Drill hole 21TK0313 was expected to result in mineralization of 1-3 meters, similar to the sheet-like patterns we have seen in nearby holes and in the CGO East area, but instead we hit 13.88 meters. This new discovery confirms our exploration model of mineralization settling, draining, and pooling, and most notably, there is no reason to think that this does not occur elsewhere along the 18 km Tamarack Intrusive Complex. Given the shallow depths of this new discovery, our rigs shoud be able to delineate this area quickly and add it to a new resource estimate later this year."

"Where there is smoke there is usually fire," said Brian Goldner, Head of Exploration. "Once we identify massive sulphides, regardless of their thickness, we can then use BHEM (geophysics) to guide the next drill hole, which is ultimately what put us onto the 13.88 meter intercept in drill hole 21TK0313 announced today. This exploration method will be applied to other zones along the 18 km Tamarack Intrusive Complex, including the 221 Zone, the 264 Zone, and the 164 Zone to evaluate for thicker accumulations of sulphides. Looking at the high-grade "smoke" in these other zones (see Figure 3 below), you can clearly see why the team is extremely excited to start work on these areas once we have finished expanding the current resource."

SUMMARY

The CGO West exploration area lies approximately 100 meters north-north-east of the Tamarack Nickel Project's resource area and extends for an additional 400 meters where past drilling showed the presence of nickel-copper mineralization. Talon has previously reported three holes that intersected massive nickel-copper mineralization (see press release dated April 7, 2021 for details) and now, with the completion of new drill holes 21TK0313, 21TK0298 and 21TK0299, Talon has drilled a total of six new holes in this area that have each intersected nickel-copper mineralization.

Drill hole 21TK0313 was a 30 meter step-out from hole 21TK0285, which intersected 27.45 meters (90.1 feet) of sulphide mineralization grading 0.75% Ni, 0.41% Cu (0.98% NiEq¹ or 2.63% CuEq²) starting at 168.2 meters, including 1.75 meters (5.7 feet) of massive sulphide grading 4.81% Ni, 1.88% Cu (5.89% NiEq or 15.72% CuEq) starting at only 193.9 meters. The drill hole was targeted with an off-hole Borehole Electro-Magnetic ("BHEM") anomaly (see Figure 2 for details).

• Drill hole 21TK0313 was targeting a down plunge extension to this BHEM anomaly and intersected 13.88 meters (45.5 feet) of mixed and massive nickel-copper mineralization starting at only 225.44 meters depth.

• This thick intercept was unexpected for this area, as the surrounding holes have patterned the sheet-like mineralization found in the CGO East area.

The mineralization in drill holes 21TK0298 and 21TK0299 correspond to off-hole Electro-Magnetic (geophysical) anomalies that were generated from historic drill holes 13TK0166 and 13TK0169.

• Drill hole 21TK0298 intersected 27.2 meters (89.2 feet) of nickel-copper mineralization beginning from 135.25 meters, and contains variable amounts of disseminated sulphide. Assays pending.

• 21TK0299 intersected 9.3 meters (30.5 feet) of nickel-copper mineralization starting at only 142.65 meters, including 1.85 meters (6.1 feet) of mixed massive sulphide from 150.1 meters to 151.95 meters. Assays pending.

These results begin to show that the CGO West area is similar in geometry to the CGO East area and have not only extended the mineralization, but also linked it throughout the northwestern portion of the CGO West area. The 13.88 meter intercept suggests that these sheets of mineralization are able to pool and collect into larger mineralized bodies, which reinforces the hypothesis that thin massive sulphide intercepts can turn into very thick intervals over a short distance.

The new massive sulphide intercepts from drill hole 21TK0313 further illustrate the potential exploration upside that exists at the Tamarack Project. To this end, the greater Tamarack Intrusive Complex already has multiple areas with massive sulphide intercepts, as shown in Figure 3. These three areas are already showing incredible grade with: drill hole 15TK0229 having intersected 1.63 meters grading 9.33% Ni, 5.14% Cu, starting at 702 meters (221 Zone); drill hole 18TK0264 having intersected 0.25 meters grading 9.95% Ni, 5.74% Cu, starting at 539 meters (264 Zone); and drill hole 12TK0164 having intersected 2.89 meters grading 3.67% Ni, 1.97% Cu (164 Zone). These areas have been largely underexplored and present a great opportunity to explore for thick deposits of massive sulphides.

Length refers to drill hole length and not True Width.
True Width is unknown at the time of publication.
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).
