Murchison Minerals Identifies Nickel-Bearing Sulphide

Mineralization Along a 5 km Trend and Significantly Expands the

HPM Project Area

May 24th, 2023 (Burlington, Ontario): Murchison Minerals Ltd. (“Murchison” or the “ Company”)

(TSXV: MUR | OTCQB: MURMF) is pleased to announce it has completed a detailed review of

data collected during the 2022 exploration program on the 100% - owned HPM (Haut-Plateau de

la Manicouagan) Project, located in Quebec . The review culminated in the identification of the

BDF Magmatic Ni-Cu-Co Trend (BDF Trend). The BDF Trend extends along a 5 km strike length to

the northwest of the Barre de Fer Deposit (BDF Deposit) and contains numerous showings of

nickel-bearing sulphide mineralization, and 7 high-priority target areas.

Figure 1: Location map of BDF Trend with highlight assay samples displayed. Nickel Equivalent (NiEq)

values were calculated using the following USD metal prices from Jan 12, 2023: $12.17/lb Nickel, $4.17/lb Copper, and

$22.23/lb Cobalt. NiEq.% was calculated using Ni%+((Cu Price/Ni Price)*Cu%)+((Co Price/Ni Price)*Co%). 100% percent

recovery is assumed for equivalent calculations, however, it should be noted that 100% recovery is not to be expected for

final recovery, and true recovery may differ significantly from element to element.

Additionally, Dr. Peter Lightfoot – Technical Advisor for Murchison Minerals – has reviewed whole

rock geochemistry from samples taken during the 2022 exploration program and has identified

the geochemical signature of the intrusive rocks that host high-grade Ni-Cu-Co mineralization at

the BDF Deposit. Based on his findings, the Company has identified a significant number of high-

priority targets that have a similar signature to BDF. Furthermore, the identification of the intrusive

host rock has led the Company to stake an additional 313.7 km2 of mineral tenements. The newly

expanded claim block covers a large area of prospective mafic-ultramafic rocks identified to the

east of the previous HPM claim area.

Highlights

• All 7 ide ntified high priority targets correspond with nickel sulphide mineralization

identified on surface (Figure 1)

• Detailed interpretation of whole rock geochemistry has identified the key host rocks

(norite & peridotite) and expanded the prospectivity of discovering new zones of nickel-

bearing sulphide mineralization beyond the BDF Trend

• Company has expanded the HPM claim block to cover an additional 313.7 km 2 of

prospective geology. The HPM Project area now totals 971.8 km2 (Figure 2)

Murchison Minerals President and CEO Troy Boisjoli comments:

“HPM is an exceptional project anchored by access to mature infrastructure, including heavy rail

with direct access to ports, road access and hydroelectricity all proximal to the project. High-grade

near surface nickel-copper-cobalt mineralization remains completely unconstrained and open at

BDF which is located at the start of a 5km trend containing multiple analogous targets. The growth

potential at BDF coupled with the discovery potential along the trend has Murchison positioned to

define the next North American nickel district”.

Qualifying Statement

The foregoing scientific and technical disclosures on the HPM Project have been reviewed by

John Shmyr, P .Geo., VP Exploration, a registered member of the Professional Engineers and

Geoscientists of Saskatchewan and current holder of a special authorization with the Ordre des

Géologues du Québec. Mr. Shmyr is a Qualified Person as defined by National Instrument 43-101.

The Qualified Person has verified the data disclosed in this release, including sampling, analytical

and test data underlying the information contained in this release. Mr. Shmyr consents to the

inclusion in the announcement of the matters based on his information in the form and context

in which it appears.

Some data disclosed in this News Release relating to sampling and drilling results is historical in

nature. Neither the Company nor a qualified per son has yet verified this data and therefore

investors should not place undue reliance on such data. In some cases, the data may be

unverifiable due to lack of drill core. Mineralization hosted on adjacent and/or nearby and/or

geologically similar properties is not necessarily indicative of mineralization hosted on the

Company's properties.

MURCHISON MINERALS LTD. NEWS RELEASE

Forward‐Looking Information

The content and grades of any mineral deposits at the Company ’s properties are conceptual in nature. There has been insufficient exploration to define a

mineral resource on the property and it is uncertain if further exploration will result in any target being delineated as a mineral resource.

Certain information set forth in this news release may contain forward -looking information that involves substantial known and unknown risks and

uncertainties. This forward-looking information is subject to numerous risks and uncertainties, certain of which are beyond the control of the Company ,

including, but not limited to, the impact of general economic conditions, industry conditions, and dependence upon regulatory approvals. FLI herein

includes, but is not limited to: future drill results; stakeholder engagement and relationships; parameters and methods used with respect to the assay

results; the prospects, if any, of the deposits; future prospects at the deposits; an d the significance of exploration activities and results. FLI is designed

to help you understand management’s current views of its near- and longer-term prospects, and it may not be appropriate for other purposes. FLI by their

nature are based on assumptions and involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance

limitation, include: the ability of exploration activities to accurately predict mineralization; the accuracy of geological modelling; the ability of the Company

to complete further exploration activities; the legitimacy of title and property interests in the deposits; the accuracy of k ey assumptions, parameters or

methods used to ob tain the assay results; the ability of the Company to obtain required approvals; the results of exploration activities; the evolution of
