LM Property
Bitterroot Resources Ltd. (51%) and its partner Below Exploration Inc. (49%) are exploring the LM Property for high-grade nickel-copper-platinum-palladium deposits similar to Lundin Mining's Eagle and Eagle East mines in the Upper Peninsula of Michigan. Four core holes totaling 1,411 metres were completed between June and August 2020. Drilling has intersected a 5.3 metre interval (4.8 metres estimated true thickness) of mafic/ultramafic rock with disseminated blebs of chalcopyrite, pentlandite and pyrrhotite. This interval grades 0.62% copper, 0.58% nickel and 0.327 grams Au+Pd+Pt/tonne. Details are included in the table below and in the Company's news release of August 24, 2020. Management is encouraged by the relatively high metal content of this disseminated mineralization. Using a formula developed by Dr. Anthony Naldrett, massive sulphides of this metal tenor should contain approximately 5.7-8.2% nickel, 7.7-8.6% copper and 1.8-4.7 ppm platinum+palladium. At Lundin Mining's Eagle Mine and elsewhere in the Mid-Continent Rift region, disseminated sulphides of this type occur around bodies of massive and semi-massive sulphide mineralization. Bitterroot and Below plan to resume drilling this highly prospective target in January 2021.
