Murchison Minerals Ltd. announce results analysed using portable x-ray fluorescence (pXRF) from the final three 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 drillholes from today's release successfully tested for mineralization along strike to the north and south of the Barre de Fer (BDF) Zone, intersecting shallow high-grade nickel-sulphide mineralization and extending the overall strike length of known mineralization to 370 m. The results further demonstrate that the BDF Zone remains open and unconstrained, along strike, and at depth. Future drilling will continue to focus on systematically expanding and delineating the BDF Zone.

The Company intends to produce a maiden resource for the BDF Zone in early 2023. 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 accurately determine the amount of mineralization (Nickel-Copper-Cobalt). The company has implemented rigorous QA/QC procedures utilizing a direct rock sampler to produce reasonably representative preliminary results.

BDF22-010 extended mineralization 45 m along strike to the South of the BDF Zone and BDF22-008 extended mineralization ~75 m along strike to the North The results to date have successfully expanded the preliminary model, the current dimensions of the BDF Zone are: Mineralization at depth has now been extended down to 475 m, versus the preliminary model at 295 m, Along strike, the zone of mineralization has been extended from 315 m to 370 m and 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. BDF22-010 intersected multiple strong intervals of mineralization including: 20.42 m estimated at 1.27% pXRF NiEq or 3.78% pXRF CuEq (between 29.21 and 49.63 m), including 4.66 m estimated at 2.93% pXRF NiEq or 8.72 CuEq (between 41.34 m and 46.0 m) 7.59 m estimated at 1.68% pXRF NiEq or 5.02% pXRF CuEq (between 56.41 to 64.0 m) including 4.03 m estimated at 2.98% pXRF NiEq or 8.88% pXRF CuEq (between 56.41 to 60.44 m).
