The 2015 winter drill program for the Minnesota-based Tamarack North nickel-copper-PGM project finished up this past March, and Talon Metals (TSX:TLO) is now in the midst of releasing results. Thus far, they seem promising — on Thursday, Talon said it's made a new discovery at the project. According to the company, it's intercepted massive nickel-copper-PGM sulfide mineralization about 1.6 kilometers from the Tamarack zone, which encompasses the current independent mineral resource estimate for the project. Specifically, drill hole 15TK0221 intercepted 0.3 meters grading 2 percent nickel, 0.56 percent copper, 0.53 g/t PGM and 0.51 g/t gold; according to Talon, that works out to 2.46 percent nickel equivalent. Drill hole 15TK0221 is part of the 480 zone, where four holes were drilled during the 2015 winter drill program. Drill holes 15TK0215 and 15TK0225 were completed about 3 kilometers north of the Tamarack zone, while drill hole 15TK0228, like drill hole 15TK0221, was completed about 1.6 kilometers to the northeast of the Tamarack zone. Prior to completing drill hole 15TK0221, Talon had not intercepted massive nickel-copper-PGM sulfide mineralization in the southern part of the 480 zone. In terms of the other 480 zone drill holes, Talon said that drill hole 15TK0228 was begun after a downhole electromagnetic survey revealed an off-hole anomaly 80 to 100 meters northwest of the hole and between 700 and 800 meters below surface. Unfortunately, warmer-than-normal weather forced the company to stop drilling prior to its completion; it will be a priority target when exploration starts up again at Tamarack North. More encouragingly, drill hole 15TK0225 intercepted 0.49 meters grading 1.15 percent nickel, 0.55 percent copper, 0.15 g/t PGM and 0.04 g/t gold, which clocks in at 1.42 percent nickel equivalent. Results from drill hole 15TK0215 are lower grade.
