Additional Nickel-Copper-PGM Mineralization And Expansion At LM Property

VANCOUVER - Bitterroot Resources Ltd. reported that the sixth hole (LM 21-10) of the 2021 winter drilling program at the LM nickel-copper-PGM project in the Upper Peninsula of Michigan has intersected an estimated true thickness of 2.1 meters of disseminated and blebby sulphide mineralization, with the sulphides consisting of chalcopyrite, pyrrhotite and pyrite. Pentlandite also has been identified within the mineralized intervals, but cannot be reliably estimated at this time. The mineralized core interval consists of 1.38 meters of 9-10% blebby sulphides that are overlain by 0.87 meters of 3% disseminated sulphide mineralization. A 0.19 meter interval of semi-massive sulphides occurs at the basal contact of the intrusion. The mineralization in hole LM 21-10 occurs mainly as chalcopyrite, pentlandite and pyrrhotite blebs and clasts. Assay results are expected in approximately 8-10 weeks.

Hole LM 21-10 intersected the sulphide-bearing mineralized interval some 50 meters laterally from the mineralization intersected in LM 20-01 and 70 meters from the mineralization intersected hole LM 21-07. All three mineralized intervals occur at approximately the same elevation, where the keel of the conduit appears to be sub-horizontal. Hole LM 21-11 is currently underway. It will be the last hole of the winter program, testing an area 50-100 meters from the previously intersected mineralization.
