Murchison Expands BDF Zone; Intersects Shallow High-Grade
Nickel-Sulphide Mineralization Including 3.67 m Estimated at
3.74% pXRF NiEq or 11.14% pXRF CuEq
October 12th, 2022 (Burlington, Ontario): Murchison Minerals Ltd. (“Murchison” or the
“Company”) (TSXV: MUR | OTCQB: MURMF ) is pleased to announce results analysed using
portable x-ray fluorescence (pXRF) from an additional five diamond drillholes, at the Barre de Fer
(“BDF”) Zone, as part of the 2022 Summer Exploration Program on the 100% - owned HPM (Haut-
Plateau de la Manicouagan) Project, located in Quebec . The holes from today’s release focused
on expansion and delineation of the known zone of mineralization - designed to support work for
the future maiden resource on BDF. The results to date have significantly expanded both the
depth and width of the modelled nickel-bearing sulphide mineralization, while further
demonstrating the potential for any future development at BDF to be open-pit amenable.
The Company completed a total of 13 diamond drillholes during the diamond drilling Phase of
2022 Summer Program, comprising 4,316 metres . Ten of the thirteen holes were drilled at BDF ,
with the remaining three being drilled at the Syrah target. Results from the first two holes at BDF
were previously released ( BDF22-001 and BDF22-002). After today’s release the Company has
pXRF results pending from six holes – three of which were drilled at BDF . The next release will
focus on the remaining holes drilled at BDF which targeted areas along strike of the currently
modelled zone of mineralization.
It should be noted that pXRF results provide only an indication of the amount of Ni, Cu, and Co
present, certified assaying of the core samples is still required to accuratel y determine the
amount of mineralization (Nickel -Copper-Cobalt). The Company has implemented rigorous
QA/QC procedures utilizing a direct rock sampler (Figure 6) to produce reasonably representative
preliminary results (see pXRF Sample Procedures and QA/QC below).
Highlights
• Drilling inter sected semi-massive sulphide mineralization as shallow as 8.50 m in
BDF22-003
• The results to date (inclusive of BDF 22-001 and 002) have successfully expanded the
preliminary model, with respect to both depth and width:

MURCHISON MINERALS LTD. NEWS RELEASE
o Mineralization at depth has now been modelled down to 450 m, versus the
preliminary model at 295 m
o Mineralization was expanded along the width of the mineralized zone from 150
m to 200 m, with individual lenses now modelled up to 48 m in thickness,
compared to the 28 m in the preliminary version
• BDF22-003 intersected 3.67 m estimate d at 3.74% pXRF NiEq or 11.14 % pXRF CuEq
(between 24.0 and 27.67 m) and 4.31 m estimate d at 2.37% pXRF NiEq or 7.08 CuEq
(between 36.69 m and 41.0 m)
• BDF22-004 intersected 9.5 m estimate at 0.79% pXRF NiEq or 2.34 % pXRF CuEq
(between 20.5 and 30.0 m), including 3.5 m estimated at 1.50% pXRF NiEq or 4.48 CuEq

Murchison Minerals President and CEO Troy Boisjoli comments:
“Today’s results continue to demonstrate the robust fundamentals of the HPM project. At Barre de
Fer we continue to intersect near surface, high-grade nickel-copper-cobalt mineralization, that is an
indication BDF would be amenable to open pit extraction. When you couple that with results from
our prospecting program that discovered multiple new mineralized sulphide showings on surface, it
adds to our confidence that we are exploring in an emerging nickel -sulphide district with advanced
infrastructure. The HPM project has road, hydroelectric facilities, and rail, all within kilometres of the
site and all within the province of Quebec – one of the best mining jurisdictions globally. With the
projected deficit in the nickel space, and the lack of viable projects globally – in the development
and exploration pipelines – have Murchison well positioned with HPM’s great fundamentals, to move
the project forward.”
Murchison Minerals Vice-President of Exploration John Shmyr comments:

MURCHISON MINERALS LTD. NEWS RELEASE
“The results we are receiving from the 2022 Barre de Fer drill campaign are encouraging from the
shear scope and scale of the sulphides intersected particularly when paired with grade of the Ni, Cu
and Co. The technical team is optimistic and we look forward to advancing BDF towards a maiden
resource as the drill results continue to exceed our expectations.”

BDF Mineralization and 2022 Delineation Drillhole Results
The mineralization observed at BDF occurs predominantly as two different types: i) Meter to multi-
metre intervals of massive and breccia ted sulphide within zones of stringer and disseminated
sulphide mineralization , hosted in gabbronorite and peridotite, ii) Disseminated sulphide with
lesser stringer to net sulphide, over broad intervals, hosted within an olivine gabbronorite. The
sulphide mineralization consists of pyrrhotite with granular pentlandite and stringer chalcopyrite,
or as chalcopyrite loops with pentlandite within massive pyrrhotite.
Hole BDF22-003 was drilled to a depth of 251 m and was designed to delineate mineralization
between hole DH-2001 and DH-151-02 (Figure 3 & 4) and test the up -dip extension of the lower
zone of sulphide mineralization intersected in BDF22-002. The drillhole successfully confirmed
the modelled mineralization , intersecting numerous meter scale intervals of massive sulphide
hosting high grade Ni-Cu-Co mineralization, delineating the gap between DDH-2001 and DDH-151-
02. Furthermore, the hole confirmed the up-dip extension of the footwall mineralization
intersected in BDF22-002.
Hole BDF22-004 was drilled to a 176 m, along a fence at the far western extent of the modelled
zone of mineralization (Figure 3 & 4). The drillhole was designed to target the up-dip extension of
mineralization intersected in DH-2001. BDF22-004 intersected shallow semi-massive to stringer
mineralization within a fault zone and proved the continuity of the mineralization to west of the
previously modelled zone.
Hole BDF22-005 was drilled to a depth of 351 m, along a fence at the northernmost extent of the
modelled zone (Figure 3). The drillhole was designed to delineate mineralization between holes
DH-151-06 and DH -2007 (Figure 5). BDF22-005 successfully intersected mineralization at the
expected interval within the model, expanding the zone of mineralization along the fence.
Hole BDF22-006 was drilled to a depth of 461 m and was designed to test the down-dip extent of
mineralization intersected in DH-151-06. The drillhole successfully inter sected mineralization
within the expected interval and expanded mineralization down-dip of previous drilling.
Hole BDF22-007 was drilled to a depth of 409 m and was designed to test down-dip extent of
mineralization intersected in 151-06, and along strike to the south of BDF22-006. The hole

successfully intersected mineralization within the expected interval and expanded mineralization
down-dip and along strike of previous drilling.

2022 Summer Diamond Drilling
During the 2022 summer exploration program, a total of 13 diamond drill holes were completed,
comprising 4,316 metres. This includes ten drillholes at BDF, and an additional three holes at
Syrah. The drill core processing has nearly concluded and pXRF results are being determined for
the remaining drillholes . Results will be released as soon as the data has been verified. The
previously released pXRF results from BDF22-001 and BDF22-002 (See September 8th Release ,
see September 14th Release and Table 3) demonstrated significant expansion below the currently
modeled mineralized domains.
All pXRF analyzed samples have also been submitted to the Saskatchewan Research Council’s
Geoanalytical Laboratory for commercial certified assaying, results are pending. The Company is
expecting final lab assay results in the coming weeks and will release final assay results once the
data becomes available. Additionally, the Company is progressing towards establishing a maiden
resource on BDF early in 2023.
