Murchison Minerals Identifies Nickel-Bearing Sulphide Mineralization Along a 5 km Trend and Significantly Expands the HPM Project Area

BURLINGTON, ON / ACCESSWIRE / May 24, 2023 / 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 identified 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 km² 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 person 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.

Forward?EUR?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.
