Bitterroot Resources Updates the LM Magmatic Nickel-Copper Project in Michigan

WEST VANCOUVER, March 9, 2022 - Bitterroot Resources Ltd. (TSXV:BTT) is providing an update on its magmatic nickel/copper drilling program on the LM Property in the Upper Peninsula of Michigan.

The LM Property is being explored for conduit-hosted nickel-copper-platinum-palladium mineralization similar to Lundin Mining Corporation's Eagle and Eagle East orebodies, which are located 25 kilometres to the east. Disseminated, semi-massive and massive sulphide Ni-Cu-PGM mineralization has been intersected in nine (9) of 25 holes completed to date on the LM Property.

Since drilling resumed at LM in mid-January 2022, Bitterroot Resources Ltd. (51%) and joint venture partner Below Exploration, Inc. (49%) have completed 1,160 metres of drilling in four (4) vertical core holes. The mineralized intervals are described in the table below. The first three holes (LM 22-22, 23 and 24) intersected 3.10, 2.04 and 5.38 metres respectively, of disseminated or blebby nickel-copper sulphide mineralization along the basal contact of the LM intrusion. Assays are expected in roughly eight (8) weeks.

Recently completed vertical hole LM 22-25 stepped out approximately 50 metres east of hole 22. This hole has generated two significant pieces of information;

1. A 5.1-metre core interval starting at 161.03 metres down-hole contains mineralized clasts of peridotite, 6-20 cm across, with disseminated and blebby nickel-copper sulphides. These mineralized clasts are suspended in a matrix of unmineralized olivine gabbronorite. They are interpreted as having been transported to their current position by a younger pulse of olivine gabbronorite magma, which eroded the clasts from an undiscovered mineralized body located deeper in the conduit.
2. LM 22-25 exited the intrusion in weakly mineralized breccia with partially resorbed siltstone clasts, at 323.09 metres down-hole. This point is 62 metres deeper than the basal contact in adjacent holes, suggesting that the base of the intrusion plunges at least -50 degrees in this area. The down-plunge extent of the conduit will be targeted in future holes.

After drill hole LM 22-26 is completed, drilling will be paused for spring break-up and is expected to resume in early May. Additional information on the LM Property is available at www.bitterrootresources.com.
