HIGHLIGHTS

• Drilling is progressing extremely well at the Tamarack Nickel Project, as Talon has consistently (now in 15 more drill holes) intersected nickel-copper mineralization at shallow depths in two areas that both lie outside of the Tamarack Nickel Project's resource area. The areas are referred to as the CGO East area and the CGO Bend area (previously referred to as the SMSU Extension area).

• The new drill holes demonstrate that the CGO East area has continuous nickel-copper mineralization over a strike length of more than 500 meters, with mineralization of 50 to 85 meters in width.

• Some of the notable results in the CGO East area so far are as follows:

• Drill hole 21TK0302 intersected 23.11 meters (75.8 feet) of nickel-copper mineralization starting at only 196.6 meters, including 1.13 meters (3.7 feet) of mixed and massive sulphide mineralization starting at only 218.58 meters;

• Drill hole 21TK0304 intersected 57.95 meters (190.1 feet) of nickel-copper mineralization starting at only 188.98 meters, including 1.67 meters (5.5 feet) of mixed massive sulphide mineralization starting at only 245.26 meters;

• Drill hole 21TK0305 intersected 31.45 meters (103.2 feet) of nickel-copper mineralization starting at only 186.05 meters, including 0.78 meters (2.6 feet) of mixed massive sulphide mineralization starting at only 216.72 meters;

• Drill hole 21TK0306 intersected 27.22 meters (89.3 feet) of nickel-copper mineralization starting at only 229.45 meters, including 1.39 meters (4.6 feet) of mixed massive sulphide mineralization starting at only 255.28 meters;

• Drill hole 21TK0309 intersected 50.1 meters (59.0 feet) of nickel-copper mineralization starting at only 232.85 meters, including 2.66 meters (8.7 feet) of mixed massive sulphide mineralization starting at only 248.17 meters;

• Drill hole 21TK0311 intersected 17.98 meters (164.4 feet) of nickel-copper mineralization starting at only 188.7 meters, including 4.3 meters (14.1 feet) of mixed massive sulphide mineralization starting at only 234.5 meters;

• Assays remain pending for all of the above-noted drill holes.

• To date, nickel-copper mineralization has been intersected in more than 60 holes within the CGO East, CGO West and CGO Bend areas. The Company plans to deliver a new resource estimate later this year or early next year.

"We are excited to now be consistently hitting nickel-copper mineralization at shallow depths in areas that lie outside of our resource area," said Brian Goldner, Vice President of Exploration for Talon. "As has been demonstrated by our recent press releases, this year is all about growing the size of the resource at the Tamarack Nickel Project, so we are in a much better position to assess and update the proposed mine plan by the end of this year. Drilling is ongoing at the Tamarack Project, with additional results coming out shortly."

SUMMARY

CGO East

The CGO East target area is large, stretching over an area of 500 meters (east-west) by 900 meters (north-south) outside of the Tamarack Nickel Project's resource area (see Talon's press releases dated November 2, 2020, December 15, 2020 and March 31, 2021 for further details). Continued drilling coupled with Borehole Electro-Magnetic ("BHEM") surveys (geophysics) confirm this area hosts shallow, wide sheets of mineralization consistent with the previously reported drill results.

The new holes announced in this press release extend mineralization to the east and west and show additional continuity of the mineralized sheet between drill holes in the southern portion of the CGO East area: (all assays remain pending)

• Drill hole 21TK0302 intersected 23.11 meters (75.8 feet) of nickel-copper mineralization starting at only 196.6 meters, including 1.13 meters (3.7 feet) of mixed and massive sulphide mineralization starting at only 218.58 meters;

• Drill hole 21TK0304 intersected 57.95 meters (190.1 feet) of nickel-copper mineralization starting at only 188.98 meters, including 1.67 meters (5.5 feet) of mixed massive sulphide mineralization starting at only 245.26 meters;

• Drill hole 21TK0305 intersected 31.45 meters (103.2 feet) of nickel-copper mineralization starting at only 186.05 meters, including 0.78 meters (2.6 feet) of mixed massive sulphide mineralization starting at only 216.72 meters;

• Drill hole 21TK0306 intersected 27.22 meters (89.3 feet) of nickel-copper mineralization starting at only 229.45 meters, including 1.39 meters (4.6 feet) of mixed massive sulphide mineralization starting at only 255.28 meters;

• Drill hole 21TK0307 intersected 1.82 meters (6.0 feet) of nickel-copper mineralization starting at only 206.7 meters, including 0.40 meters (1.3 feet) of mixed massive sulphide mineralization starting at only 208.12 meters;

• Drill hole 21TK0308 intersected 27.83 meters (6.0 feet) of nickel-copper mineralization starting at only 206.7 meters, and 0.78 meters (2.6 feet) of mixed massive sulphide mineralization starting at only 223.18 meters;

• Drill hole 21TK0309 intersected 50.1 meters (59.0 feet) of nickel-copper mineralization starting at only 232.85 meters, including 2.66 meters (8.7 feet) of mixed massive sulphide mineralization starting at only 248.17 meters;

• Drill hole 21TK0311 intersected 17.98 meters (164.4 feet) of nickel-copper mineralization starting at only 188.7 meters, including 4.3 meters (14.1 feet) of mixed massive sulphide mineralization starting at only 234.5 meters; and

• Drill hole 21TK0318 intersected an upper zone of 6.1 meters (20.0 feet) of nickel-copper mineralization starting at only 230.73 meters, and a lower zone of 7.88 meters (25.9 feet) of nickel-copper mineralization starting at only 243.84 meters, including 1.39 meters (4.6 feet) of mixed massive sulphide mineralization starting at only 250.33 meters.

These results provide further confirmation of the continuous trend of nickel-copper mineralization modelled by Talon using surface and BHEM data (geophysics). This consistent mineralized zone typically begins with large, shallow and thick disseminated sulphide mineralization above a sheet of higher-grade massive sulphide mineralization. Previously reported assay results (see the Company's press release dated May 4, 2021) have intervals with nickel grades up to 5.2% Ni combined with copper grades up to 1.7% Cu in the massive and mixed massive sulphide sheet.

Talon plans to continue drilling the CGO East area with the goal of delineating a resource that could be added to the current mine plan.

CGO Bend

The CGO Bend is a zone that lies between the CGO East and CGO West areas that is composed of low grade mineralized coarse-grained olivine ("CGO"). Historically 6 holes were drilled into this area along the strike-length of the CGO Bend, so Talon set out to drill holes towards the edges to determine where the contact is between the CGO East/West and the CGO Bend and to identify if it is mineralized. The drilling conducted showed that not only did the CGO Bend extend further east than expected, but it also contained thicker zones of mineralization than expected with holes intersecting up to 42 meters of disseminated mineralization as shown below.

In summary:

• Drill hole 21TK0280 intersected 8.22 meters (27.0 feet) of nickel-copper mineralization starting at only 98.23 meters and 17.43 meters (57.2 feet) of nickel-copper mineralization starting at only 125.12 meters.

• Drill hole 21TK0281 intersected 42.06 meters (138.0 feet) of nickel-copper mineralization starting at only 127.71 meters and 1.36 meters (4.5 feet) of mixed and massive nickel-copper mineralization starting at only 195.54 meters.

• Drill hole 21TK0284 intersected 27.69 meters (90.8 feet) of nickel-copper mineralization starting at only 100.36 meters.

• Drill hole 21TK0297 intersected 5.1 meters (16.7 feet) of nickel-copper mineralization starting at only 247.45 meters.

• Drill hole 21TK0300 intersected 18.29 meters (60.0 feet) of nickel-copper mineralization starting at only 127.71 meters and 0.41 meters (1.3 feet) of mixed and massive nickel-copper mineralization starting at only 196.28 meters.

• Drill hole 21TK0310 intersected 42.52 meters (139.5 feet) of nickel-copper mineralization starting at only 170.08 meters.

The mineralization in the CGO Bend area appears to be shallow and bulky, over a strike length of 300 meters.
