Murchison Minerals Commences Summer Exploration Program and Completes Large Scale VTEM Survey on its 100% Owned HPM Ni-Cu-Co Project Identifying a Significant Number of New EM Anomalies

BURLINGTON, ON / ACCESSWIRE / July 7, 2022 / Murchison Minerals Ltd. ("Murchison" or the "Company") (TSXV:MUR OTCQB:MURMF) is pleased to announce the commencement of its summer exploration program with crews mobilizing to site mid-June, and the start of the prospecting phase of the program on the 100% - owned HPM (Haut-Plateau de la Manicouagan) Project, located in Quebec. Furthermore, the Company has also begun the process of probing previous drill collars at the Barre de Fer (BDF) Zone with a downhole borehole electromagnetic (EM) survey. The borehole EM surveys will help refine and target areas of expansion and delineation for the upcoming drilling phase of the summer program. Additionally, the Company also recently completed the initial 3212 line-km airborne EM survey, at 200 metre spacing, which commenced in April of 2022, and covers the remaining 85% of the HPM claim block. The preliminary results from the VTEM survey have detected a significant number of new prospective geophysical anomalies. Due to the newly detected anomalies, the Company has staked an additional 72 km² of claims contiguous to the currently defined HPM property; HPM's property area is now 648 km². The Company has also begun flying an additional 980 line-km near the newly located prospective anomalies at 100 metre line spacing.

HPM Regional Prospecting Program

The Company has completed mobilization of a temporary work camp that will support the diamond drilling phase of the summer exploration program as well as the currently ongoing prospecting program. The prospecting program consists of 3 teams which are utilizing GDD's "Beep Mat" technology to locate near surface nickel-bearing sulphide mineralization associated with the newly identified geophysical anomalies. Any anomalies that are detected using the Beep Mat are then sampled using a small backpack diamond drill. Preliminary work at the BDF Zone has been successful in locating multiple new areas of surface mineralization, assays are pending for those samples (Figure 1).

Advancing Exploration at BDF

In concurrence with the ongoing prospecting program, the Company has commenced borehole EM surveying on previously drilled holes at the BDF Zone. Additionally, the lone hole previously drilled at the nearby Syrah Target - which is interpreted to have missed the geophysical target -has also been surveyed. The borehole EM survey at Syrah has detected an off-hole EM response which is indicative of potential nickel bearing sulphide mineralization. The borehole EM work is ongoing, and the Company will use the results to better refine areas for expansion at the BDF Zone as well as to assist in drill targeting at the prospective Syrah Target.
