Vulcan Minerals Inc. - Drilling to Resume at Carbonear Zinc-Lead SEDEX project in Newfoundland

Executive Summary

• Vulcan Minerals Inc. announces the resumption of its drilling program at the Carbonear Project in Newfoundland, with drill mobilization scheduled for mid-June 2026.
• The company reports encouraging assay results from the previously completed hole CP-26-11, highlighting anomalous zinc and lead mineralization consistent with a potential SEDEX-type deposit.
• The remaining exploration program will consist of five holes totaling approximately 1,000 meters of diamond core drilling, supported by an application for a provincially funded Junior Exploration Assistance grant.

Key Details

• Drilling Program Status: Resumption of drilling at the Carbonear Project; initial program suspended over winter due to weather-related access issues, with one hole (CP-26-11) completed prior to suspension.
• Remaining Program Scope: Five additional holes for approximately 1,000 meters of diamond core drilling.
• Assay Results (Hole CP-26-11):
• 0.113% zinc over 31.15 meters from 12.1m to 43.25m
• Includes 0.264% zinc and 0.101% lead over 7.5 meters from 28.5m to 36m
• Geological Context: Results indicate anomalous zinc-lead mineralization associated with widespread disseminated and fracture-filling pyrrhotite and pyrite, characteristic of SEDEX deposits. The hole served primarily as a stratigraphic tool to correlate sedimentary sequences with geophysical signatures.
• Target Area: Focus on a 2-kilometer section of a stratigraphic zone extending over 12 kilometers along strike with an average width of 1.5 kilometers, situated within a thick marine basinal sequence (>6km) of shale, siltstone, and sandstone.
• Funding: Application submitted for a provincially funded Junior Exploration Assistance (JEA) grant for 2026 exploration activities.
• Quality Control: All samples assayed by SGS Natural Resources using four-acid digestion/ICP-OES for base metals and fire assay/AAS for gold; 5% standard reference materials utilized; internal SGS duplicate analyses confirm proper sample preparation and calibration.
• Corporate Updates: Launch of an upgraded corporate website (www.vulcanminerals.ca); Company holds approximately 26.52% ownership in Atlas Salt Inc. (TSXV: SALT).

Notable Quotes

• Patrick Laracy, President: "Hole CP-26-11 is primarily a stratigraphic hole in order to better understand the sedimentary sequence in relation to its geophysical signature. We are pleased to see anomalous zinc-lead mineralization associated with widespread disseminated and fracture filling pyrrhotite and pyrite, minerals associated with Sedex deposits. Though the results are not ore grade, they speak to the pervasive presence of zinc and lead in the right prospective geological setting. The Carbonear property represents an exciting grass roots exploration project and we look forward to completing this early-stage drill program."
