Murchison Minerals Appoints Dr. Stephen Piercey as Technical Advisor and Provides an Update on the BMK Zinc-Copper-Silver-Lead-Gold Project
June 7th, 2023 (Burlington, Ontario): Murchison Minerals Ltd. (“Murchison” or the “Company”) (TSXV: MUR | OTCQB: MURMF) is pleased to announce that it has appointed renowned volcanogenic massive sulfide (VMS) deposits expert Dr. Stephen Piercey as technical advisor for the 100% owned Brabant-McKenzie (BMK) project located in Saskatchewan, Canada.
Based on the work Dr. Piercey and Murchison’s technical team completed this Spring the Company believes that the BMK Deposit area is prospective to host a copper-rich stockwork zone, similar in style to Foran Mining’s Mcllvenna Bay Project. Additionally, Murchison’s technical team has identified a 37 km trend (BMK Trend) which has numerous showings of VMS mineralization, leading to the high potential of discovering further VMS deposits along strike of the BMK Deposit. Accordingly, Murchison has staked an additional 75 km2 of mineral claims encompassing the entire BMK Trend.
- Appoints VMS expert, Dr. Stephen Piercey, as technical advisor for BMK VMS Project.
- Review of the BMK Deposit indicates strong potential for a copper-rich stockwork zone (Figure 2). This would be similar in style to Foran Mining’s Mcllvenna Bay Deposit, where a significant copper stockworks zone, associated with the zone of zinc-rich massive sulphide was discovered.
- VMS systems typically form in clusters, and the BMK Deposit is the only VMS deposit that has been discovered and delineated at the BMK Project. However, VMS-style mineralization has been discovered at numerous targets along the BMK Trend (Figure 1), including:
- Main Lake where a 0.89 m backpack drillhole intersected 8.31% Zn, 6.17% Cu, 140 g/t Ag, and 0.2 g/t Au
- Betty Zone where diamond drilling intersected 0.92 m grading 4.40% Zn, 1.33% Cu, and 12.95 g/t Ag
- The BMK Trend is highly prospective for the discovery of additional copper-zinc rich VMS deposits.
- Identification of the BMK Trend, a ~37 km strike length of favourable stratigraphy and VMS style mineralization, extending from Main Lake Target in the South to the Street Lake Target in the North.
- The Company has staked an additional ~75 km2 of claims along strike to the northwest of the main BMK Project area, encompassing the entire prospective BMK Trend.
- The BMK Project area now totals ~655 km2, with excellent existing infrastructure directly adjacent to the project area.

Dr. Stephen Piercey
Dr. Piercey has conducted extensive research and field work, internationally and across Canada, focusing on VMS deposits and their origins. Dr. Piercey is University Research Professor in the Department of Earth Sciences at Memorial University as well as a part-time consultant with SJPGeoConsulting out of St. John’s, NFLD. He is a previous winner of the Lindgren Medal (SEG), W.H. Gross Medal (MDD-GAC), Howard Street Robinson Medal (MDD-GAC), Hutchison Medal (GAC), and the Duncan Derry Medal (MDD-GAC). Presently, Dr. Piercey is the President Elect of the Society of Economic Geologist, is a Professional Geoscientist (PGeo) in Newfoundland and Labrador, Ontario, and Saskatchewan, and was awarded Fellow of Geoscientists Canada for his contributions to the geoscience profession in Canada.
Brabant-McKenzie VMS Project Review
During the Spring of 2023 Murchison Minerals, with the assistance of Dr. Piercey, completed the systematic relogging and sampling of historic drill core at the BMK Deposit, as well as at the regional targets called Main Lake, Betty, T2T and TOM2. The work has successfully identified the BMK Deposit as a felsic volcaniclastic-type of VMS deposit, which is similar to those in the past-producing, high tonnage Bathurst VMS Mining Camp in New Brunswick. These sediment-rich VMS environments host some of the highest tonnage VMS deposits globally. The Bathurst-type VMS deposits typically have abundant zinc-rich sulfides that are underlain by a copper-rich stockwork “feeder” zones. It is inferred that one may exist proximal to the BMK Deposit or within the region. A top priority for the Company is locating the copper-rich zone at the BMK Deposit.
The relogging work has also identified the volcaniclastic stratigraphy (37 km strike length) that hosts the BMK Deposit, termed the BMK Trend. Murchison currently has multiple targets along the BMK Trend (Figure 4) which include the Betty and Main Lake targets. At the Main Lake and Betty targets, Murchison discovered initial VMS mineralization in 2020 and 2021 (Table 2). The BMK Deposit and the Betty and Main Lake Targets remain open and are ideally located adjacent to a provincial highway and power. The company has staked an additional 7487 hectares of claims, encompassing the entire prospective BMK Trend. The BMK Project now has area comprising 65,501 hectares or 655 km2.
”“I would like to welcome Dr. Stephen Piercy as a technical advisor to Murchison Minerals. Dr. Piercy recently visited our BMK project in Saskatchewan, where he has helped to further our technical team’s understanding and approach to unlocking the copper potential at BMK. Polymetallic VMS deposits, like BMK, are some of the world’s most important sources of key critical minerals. These deposit types tend to occur in clusters, where on the average Canadian VMS camp contains nine deposits. The BMK Deposit is the first zone of mineralization that’s been discovered and delineated along the 37 km BMK Trend; however, our technical team has already discovered numerous additional showings of VMS mineralization within the BMK Trend. As the world continues to transition away from fossil fuels, critical minerals projects, like BMK, will help source the metals needed to power that future.”Troy BoisjoliMurchison Minerals President and CEO
”“The geological setting of the BMK Deposit is similar to other volcaniclastic-hosted deposits globally, including deposits in the Bathurst Mining Camp in New Brunswick. In many cases, volcaniclastic- and sediment-rich environments host high tonnage VMS deposits. Moreover, the high zinc grades found at BMK are common to zone-refined VMS deposits, where zinc-rich zones are frequently underlain by copper-rich stockwork/feeder zones. That these copper-rich zones have yet to be identified in the Brabant Lake region is interesting, but not surprising given the structural/metamorphic setting of the belt. Nevertheless, it suggests that such zones be present in the region and should be considered high priority exploration targets.”Dr. Stephen PierceyTechnical Advisor
