BITTERROOT RESOURCES INTERSECTS SEMI-MASSIVE AND
DISSEMINATED SULPHIDES AT THE
LM NICKEL-COPPER-PGM PROJECT IN MICHIGAN
Bitterroot Resources Ltd. ( symbol BTT, TSX-V ) reports that the th ird hole of its 2021
winter drilling program at the LM nickel-copper-PGM project (LM 21-07) has intersected
an estimated true thickness of 3.55 metres of sulphide mineralization, with the sulphides
consisting of chalcopyrite, pentlandite, pyrr hotite and pyrite. The mineralized interval
consists of an estimated true thickness of 0.5 metres of se mi-massive sulphides that are
overlain by an estimated true thickness of 3.05 metres of diss eminated sulphide
mineralization. The latter occurs mainly as in terstitial chalcopyrite and pyrrhotite grains
and blebs similar to the mineralization previously intersected in hole LM 20-01 (see news
release dated August 24, 2020). Assay results are expected in 6-8 weeks. A description of
the mineralized intervals is provided in the table below. A 3-dimensional model of the drill
holes and photos of the mineralized in tervals in both holes are posted on
www.bitterrootresources.com.

Hole LM 21-07 intersected the sulphide-bearing min eralized interval some 54 metres
laterally from the mineralization intersected in LM 20-01 , at approximately the same
elevation. Hole LM 21-09 is currently being drilled to test approximately 80 metres down
plunge from the mineralizat ion intersected in holes LM 20-01 and LM 21-07. Although
the other three holes drilled this winter (LM 21-04, 05 and 08) exited the intrusion above
the mineralized zone, they provide valuable information regarding the geometry of the LM
magma conduit.
Encouraging aspects of hole LM 21-07 are;
1. At 271.9 metres down hole, ultr amafic rocks host what ap pears to be a clast of
massive chalcopyrite which is interpreted as a “rip-up” clast from deeper in the
conduit.
2. the sulphide mineralization is hosted by intrusive breccia, which suggests
proximity to the keel of the flattening LM intrusion, where massive sulphides
would be expected to accumulate,
3. Down-hole magnetic surveys show str ong, localized magne tic variability
immediately below the mineralized intervals in LM 20-01 and LM 21-07 ,
suggesting the potential for additional magnetic bodies nearby,
4. Differentiated sulphide-bearing intervals suggests that the LM conduit had a long
thermal history which allowed fractionation into chalcopyrite-rich and pyrrhotite-
rich phases.
Exploration of the LM Project is being funded by Bitterroot Resources Ltd. (51%) and
privately-owned joint venture partner Below Exploration Inc. (49%). Bitterroot and Below
are currently drilling the fifth hole of the 2021 winter drill program, which is planned to
comprise up to 2,400 meters of core drilling in 6 to 8 holes, before spring break-up.
