[{"type":"text","content":"Bitterroot Resources Confirms High Nickel Grades in Semi-Massive Sulphide MineralizationVANCOUVER, BC / ACCESSWIRE / March 30, 2021 / Bitterroot Resources Ltd. (TSXV:BTT) has received assays for hole LM 21-07 at its LM Project in the Upper Peninsula of Michigan. The assays confirm that semi-massive sulphides intersected in hole LM 21-07 are enriched in nickel and copper, as previously modelled. The mineralized interval consists of an estimated true thickness of 3.50 metres containing 0.71 metres of semi-massive sulphides grading 5.16% nickel and 1.18% copper, overlain by an estimated true thickness of 2.79 metres of disseminated sulphide mineralization grading 0.78% nickel and 0.83% copper.LM 21-07: Estimated True Thickness of Mineralized IntervalsInterval(m)Rock TypeNi (%)Cu (%)Au + PGM (ppm)2.79Upper Disseminated Mineralization - Est.

This \"rip-up\" clast was transported along the conduit by magmatic processes, suggesting the presence of a nearby body of high-grade, copper-nickel rich massive sulphide,The nickel and copper grade of the disseminated mineralization in hole LM 21-07 is 34% higher than the grade of the disseminated mineralization intersected in hole LM 20-01,The increasing grades and sulphide content of LM 21-07 compared to mineralization in LM 20-01 and LM 21-10 provides a vector to potential areas of higher-grade massi...
