Murchison Minerals Completes Lithogeochemical Study at the BMK Cu-Zn-Ag-Pb-Au VMS Project in Saskatchewan and Identifies New Precious Metals Zone, Assays Return Grades up to 7.17 g/t Gold, 663 g/t Silver and 4.57% Lead

May 14th, 2024 (Burlington, Ontario): Murchison Minerals Ltd. (“Murchison” or the “Company”) (TSXV: MUR | OTC: MURMF) is pleased to announce results from a comprehensive Lithogeochemical Study of the Host Rocks at the BMK Deposit and associated VMS showings (the “Study”) along the 37 km BMK Trend at its 100%-owned Cu-Zn-Ag-Pb-Au Volcanogenic Massive Sulphide (VMS) BMK Project in Saskatchewan.

The Study was conducted by Dr. Stephen J. Piercey (SJPGeoConsulting, St. John’s, NL.), University Research Professor in the Department of Earth Sciences at Memorial University, NL who is a globally recognized VMS expert. The Study focused on analyzing the geochemical signatures of the rock and alteration types at the BMK Project. Findings from the study are based on data collected from the Company’s Spring 2023 re-logging and re-sampling program, which analyzed samples from a selection of drill holes from across the BMK Trend. The re-logging and sample selection was conducted by Dr. Piercey with support from Murchison’s Exploration team. Results from the Study confirm the geological setting of the BMK Deposit and associated VMS showings as having formed in a volcaniclastic- and silicic-dominated dominated back-arc basin with mineralization associated with felsic volcaniclastic rocks, similar to other felsic-siliciclastic VMS districts globally, including the Bathurst Mining Camp (NB) and the Finlayson Lake district (Yukon). Results provides further evidence in support of the Company’s thesis, that the BMK Project area is highly prospective to host additional VMS deposits.

As part of the Study, the Company selected drill hole BR07-39 for re-logging and re-sampling – the hole was drilled through the centre of the BMK Deposit. Assay results from an interval of BR07-39 located below the lower zone of mineralization at the BMK Deposit – an interval previously thought to be barren – returned high-grade Gold-Silver-Lead (Au-Ag-Pb) mineralization. The newly identified Au-Ag-Pb mineralization is associated with cryptic galena (Figure 3). Other drill holes across the BMK Deposit have intersected similar rock units, indicating a previously unidentified precious metals zone has been discovered. The Company is currently planning additional re-sampling to confirm the size and grade of the Gold-rich zone.


  • Dr. Stephen J. Piercey, VMS expert, completed a lithogeochemical study of host rocks at the Company’s BMK VMS Deposit and associated regional VMS targets situated on the 37 km long BMK Trend (Figure 1).
  • The Study confirms that the volcaniclastic- and sedimentary-rich assemblages within the BMK Trend are typical of those hosting high tonnage VMS deposits and districts globally, such as those observed in the high-grade VMS Bathurst Mining Camp, New Brunswick
  • New zone of precious metals, gold-silver-lead (Au-Ag-Pb) mineralization, has been identified at the BMK Deposit:
    • Assay results from a previously unsampled interval of drill hole BR07-39 – situated below the lower zone of VMS mineralization at the BMK Deposit – returned grades of 0.84 g/t Au, 95.05 g/t Ag, & 0.48% Pb over 5.75 metres including 7.17 g/t Au, 663 g/t Ag & 4.57% Pb over 0.5 metres.
    • The Company has identified similar lithological and alteration assemblages that are associated with the Au-Ag-Pb mineralization (Figure 3) in previously unsampled sections of other drill holes across the BMK Deposit – highlighting the prospectivity of growing the precious metals component of the Deposit in future resource updates.
  • Regionally, the study confirmed host lithologies and alteration types found at Main Lake (along strike to the south of BMK) and the Betty Target (located on strike to the north) are well developed and consistent with that observed at the BMK Deposit, verifying the prospectivity of the BMK Trend to host additional VMS Deposits.

Murchison Minerals’ Technical Advisor Dr. Stephen J. Piercey comments:

It is nice to see the geochemistry verify what we anticipated based on the geological investigations of the drill core in 2023. The lithofacies and mineralization styles in the core are very similar to what we see in other metamorphosed felsic-siliciclastic VMS districts globally, and the lithogeochemical signatures of those rocks are also like signatures found in the host rocks in these districts. In addition, alteration signatures recorded in the host rock lithogeochemistry in the Main Lake and Betty prospects are similar to the Brabant-Mackenzie deposit illustrating that VMS alteration processes occurred elsewhere in the BMK Trend and that these areas are high-priority targets for further exploration and VMS targeting."

Murchison Minerals’ Vice-President of Exploration John Shmyr comments:

Findings from the Study demonstrate the continuation of prospective lithological and alteration assemblages along the 37 km BMK Trend, indicating the geological setting is right to host additional VMS deposits. Additionally, the new precious metals discovery at the BMK Deposit is extremely exciting and has the potential to add significant value to future resource updates. The Company is planning a robust relogging and resampling program on all off its historic drill holes at the BMK Deposit. The objective of which will be to determine the size and scale of the new zone and the potential identification of additional zones.”

Murchison has implemented and is adhering to a strict quality assurance/quality control program. NQ-size core mineralized intervals were marked by geologists during core description. The marked intervals were sampled using a core saw, one-half is kept as a witness sample at core facility in Brabant Lake, Saskatchewan and the other assigned a unique number and placed within a plastic bag. Samples were shipped directly to SRC Geoanalytical Labs in Saskatoon, Saskatchewan. The samples were ground and prepared for analysis by the lab using total digestion. Analyzes were performed using inductively coupled plasma optical emission spectroscopy (ICP-OES) for copper, zinc, lead and silver. Gold was analyzed by fire assay. Every 25th sample sent to the lab was a field duplicate (quarter core), blanks and certified reference material were also submitted approximately every 25th sample. All analyses were undertaken at SRC Geoanalytical Laboratories located in Saskatoon, Saskatchewan.
