- Drill hole 21TK0317 intersected 5.23 meters (17.2 feet) of mixed and massive nickel-copper mineralization grading 5.29% Ni, 2.13% Cu (6.36% NiEq or 16.97% CuEq) starting at only 247.97 meters.
- Drill hole 21TK0323 intersected 13.25 meters (43.5 feet) of mixed and massive nickel-copper mineralization grading 3.97% Ni, 1.48% Cu (4.82% NiEq or 12.85% CuEq) starting at only 190.75 meters.
- Drilling remains ongoing to further expand this enriched high-grade zone of nickel-copper mineralization within the CGO West area.
“Grade is ‘king’ in mining, and our recent drill results of 8% to 12% nickel and 11% to 16% copper could be a king maker,” said Brian Goldner, Vice President of Exploration. Goldner continued: “Not only are we proving a new dimension of the Tamarack Intrusive Complex with these best-ever drill results at the newly discovered CGO West location, but we are also showing that the mineralization is shallow and large scale. The more we drill, the more we understand how the Tamarack Nickel Project can be a vital source of strength for the US EV battery supply chain.”
The CGO West area lies approximately 100 meters north-north-east of the Tamarack Nickel Project’s resource area and extends for an additional 400 meters where drilling shows the presence of shallow, high-grade nickel-copper mineralization. Talon has previously reported 18 drill holes within the CGO West area, all of which have intersected nickel-copper mineralization. The thick intersections of mixed and massive sulphides are found at the base of the overlying Fine-grained Orthocumulate (“FGO”) and Coarse-grained Orthocumulate (“CGO”) intrusions where they appear to form ‘pools’ of nickel and copper rich sulphides (see Figures 4 and 5).
Drill hole 21TK0313 (which represents the initial ‘discovery hole’ in the CGO West area) was drilled to test a Bore Hole Electromagnetic (geophysical) anomaly and successfully intersected 13.92 meters (45.7 feet) of mixed and massive nickel-copper sulphide mineralization at 225.44 meters depth assaying 5.54% Ni, 2.14% Cu, 0.16% Co, 0.21 g/t Pd, 0.26 g/t Pt and 0.08 g/t Au (6.70% NiEq or 17.86% CuEq) (see the Company’s press release dated July 6, 2021).
Following drill hole 21TK0313, Talon’s normal practice of utilizing Bore Hole Electromagnetic surveying continued to identify new electromagnetic anomalies in the CGO West area, which resulted in the mixed and massive nickel-copper mineralization to be further expanded. Results of that follow-up drilling have been reported in the Company’s press releases dated July 6, 2021 and August 5, 2021.
Today, the Company is pleased to announce the following new drill hole assays within the CGO West area:
- Drill hole 21TK0330 intersected 4.44 meters (14.6 feet) of mixed and massive nickel-copper mineralization grading 7.97% Ni, 11.25% Cu, 0.09% Co, 2.72 g/t Pd, 3.21 g/t Pt and 2.98 g/t Au (14.08% NiEq or 37.56% CuEq) starting at only 269.13 meters.
- Drill hole 21TK0317 intersected 5.23 meters (17.2 feet) of mixed and massive nickel-copper mineralization grading 5.29% Ni, 2.13% Cu, 0.13% Co, 0.17g/t Pd, 0.17 g/t Pt and 0.08 g/t Au (6.36% NiEq or 16.97% CuEq) starting at only 247.97 meters.
- In addition, drill hole 21TK0317 also intersected 9.74 meters (32.0 feet) grading 0.71% Ni, 0.46% Cu, 0.02% Co, 0.09 g/t Pd, 0.13 g/t Pt and 0.08 g/t Au (0.96% NiEq or 2.57 % CuEq) starting at 212.21 meters.
- Drill hole 21TK0323 intersected 13.25 meters (43.5 feet) of mixed and massive nickel-copper mineralization grading 3.97% Ni, 1.48% Cu, 0.12% Co, 0.22 g/t Pd, 0.28 g/t Pt and 0.10 g/t Au (4.82% NiEq or 12.85% CuEq) starting at only 190.75 meters.
The mineralization in drill hole 21TK0330 is deeper than the large ‘pool’ of massive sulphide mineralization previously reported in the CGO West area (although still considered shallow), a fact that may be related to its very high metal grades.
Upon first inspection of the drill core from drill hole 21TK0330, Talon’s geologists immediately recognized that it contained an unusually large amount of nickel and copper sulphide minerals, but very little iron sulphide minerals. The extremely high grades assayed in the mixed and massive sulphide mineralization are thought to be the result of the nickel and copper sulphides separating from the iron sulphides. This natural process of enrichment can occur where the molten sulphide minerals cool slowly over time, which allows the nickel and copper sulphides to drain away from the main pool before finally solidifying. In this case, the enriched liquid sulphides appear to have flowed downward at a steep angle similar to the way water falls from the edge of a pool.
Multiple new Borehole Electromagnetic (geophysical) anomalies suggest that the enriched sulphides at depth in drill hole 21TK0330 may extend laterally (see Figure 3) and potentially to greater depths. Drill testing of these anomalies to expand the high-grade enriched sulphide zone is planned.
The results reported today, combined with those from past press releases show that the CGO West area has the following exciting characteristics:
- High Grades – The new assays from drill hole 21TK0330 have the highest interval of nickel and copper grades ever found anywhere within the 18 km Tamarack Intrusive Complex. Combined with the assays reported for drill holes 21TK0313, 21TK0317, and 21TK0323, the Company is seeing widespread high grades of nickel and copper over long sections of core that demonstrate the large volume of nickel and copper within the CGO West area.
- Size – The size of the CGO West area’s ‘pool’ of sulphides continues to increase as new holes are drilled. There is 125 meters of distance between drill holes 21TK0316 and 21TK0323 (see Figure 3). Between these two holes are 5 additional drill holes that have also intersected thick massive and mixed massive sulphides and demonstrate the potential for continuity of the large pool of high-grade sulphides over a large area.
- Favorable Location – The high-grade sulphide ‘pool’ is at shallow depths and lies up slope from the Tamarack Nickel Project’s resource area. Consequently, it is expected to be mined near the beginning of the mine life, resulting in early cash flows.
- Potential to Grow – Talon has not yet found the edges of this ‘pool’ of massive sulphide. New Borehole Electromagnetic (geophysical) anomalies…
