Green Bridge Metals Corporation (CSE:GRBM)(OTCQB:GBMCF)(FWB:J48, WKN: A3EW4S) has completed re-sampling work for historical core assay and geophysics data at its Skibo Prospect in Minnesota’s South Contact District, Duluth Complex. The new data supports the definition of a coherent magmatic copper (Cu)-nickel (Ni)-platinum group metal (PGM) system spatially associated with electromagnetic conductors, strengthening the company’s geological targeting framework.
Disseminated Cu-Ni-PGM mineralization was identified over intervals exceeding 200-400 meters in multiple historic holes. High-grade massive and semi-massive sulfide intercepts are spatially associated with mapped electromagnetic conductors. Conductive anomalies are interpreted to extend between two historic drill clusters, supporting potential system continuity. The integrated geological and geophysical model establishes a repeatable targeting framework for future drilling. The geological model was enhanced through a low-cost historic core sampling program (under US$180,000).
The resampling program of historical drill core has indicated the presence of massive and semi-massive Cu-Ni-PGM intervals at Skibo. The goal of this program was to target unsampled intervals above and below historical assay intervals that report high-grade zones. Sampling of the historical drill core is expected to allow the Company to evaluate whether disseminated mineralization halos exist and to assess their spatial relationship to mapped electromagnetic conductors.
Results from the re-sampling work confirmed that massive sulfide veins occur within broader disseminated halos extending over substantial downhole lengths. The highest-grade intercepts are spatially associated with mapped electromagnetic conductors, supporting the interpretation that these conductors represent mineralized sulfide trends rather than isolated occurrences. The table of results reflects significant intervals of mineralization in the core that integrates both the historical assay results with the new assay intervals completed by the Company. This reflects a more complete picture of the extent and tenor of mineralization the historical drillhole dataset. For reports of the historical drill hole and assay data please see the Company’s Technical Report titled, “Technical Report and Mineral Resource Estimate for the South Contact Zone Project, St Louis County, Minnesota, USA” with an effective date of September 18, 2024.
The relationship between mineralization and electromagnetic conductors establishes a repeatable, data-supported targeting methodology for future drill programs. Historical drill holes that are observed to have strong Cu-Ni-PGM mineralization are spatially correlated with mapped electromagnetic conductors. Where historical drill holes were observed to have modest Cu-Ni-PGMM mineralization, they are not spatially coincident with the electromagnetic conductors. Future exploration plans will focus on testing electromagnetic conductor trends and step-out targets between and beyond historic core holes.
Mineralization at Skibo occurs along the basal contact of the Duluth Complex, a geological setting that hosts several copper-nickel deposits in Minnesota. While exploration at Skibo remains at an early stage, the style of mineralization, presence of thick disseminated halos, and association with geophysical conductors are consistent with magmatic sulfide systems elsewhere in the district.
“These early results are encouraging and advance our understanding of Skibo,” said David Suda, President and CEO of Green Bridge Metals. “This gives us a clear and disciplined path for further exploration. Skibo is emerging as a serious opportunity within our district portfolio.”
Green Bridge Metals is advancing critical mineral assets in North America, with a focus on the Duluth Complex’s South Contact Zone. The company’s projects target copper, nickel, PGMs, cobalt, and titanium to support global electrification and infrastructure needs.
