Murchison Minerals Ltd. announced assay results for the remaining eight diamond drillholes, from the Barre de Fer ("BDF") Zone, drilled 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 expanded mineralization down dip as well as along strike to the north and south of the Barre de Fer (BDF) Zone. The results confirm the previously released pXRF results and 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. During the 2022 summer exploration program at HPM, a total of 13 diamond drillholes were completed, comprising 4,316 metres. This includes 1) drill holes at BDF, and an additional 3 holes at Syrah.

The pXRF results for the ten holes drilled at BDF were previously released and lab assays have now been released for all drilling completed at BDF. release of lab assay results as well as the previously released assay results from BDF22-001 & 002 validate the rigorous Direct Rock Sampling (DRS) Portable X-Ray Fluorescence (pXRF) process that the Company developed in advance of the 2022 Summer Exploration Program. The DRS process allowed the Company to produce near laboratory quality results in the field.

In turn, this process enabled the Company to model zones of mineralization in real time, creating a dynamic exploration process which was unaffected by laboratory delays faced by many industry peers. Murchison expects to release the assay results from the remaining 3 drillholes completed at the Syrah target once results have been finalized and interpreted. The mineralization observed at BDF occurs predominantly as two different types: i) Meter to multi-metre intervals of massive and brecciated 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 a gabbronorite.

The sulphide mineralization consists of pyrrhotite with granular pentlandite and stringer chalcopyrite, or as chalcopyrite loops with pentlandite within massive pyrrhotite.
