VANCOUVER, BC, July 16, 2026 /CNW/ -- Metallis Resources Inc. (TSXV: MTS) (OTCQB: MTLFF) (the "Company" or "Metallis") is pleased to announce that diamond drilling is now underway at its Greyhound Property ("Greyhound" or the "Project") in central Idaho, marking the next phase of the Company's 2026 exploration program.
Following the successful completion of mobilization activities announced last week, construction of the exploration camp has been completed, and the site is now fully operational. The diamond drill arrived at camp on July 8, and has since been commissioned, with the Company's geological team completing final drill collar surveying and staking in preparation for the season's first drill hole.
The 2026 drill program will initially focus on the Rufus Zone, where the Company's 2025 exploration campaign confirmed a broad mineralized shear zone hosting multiple quartz-sulphide veins carrying anomalous gold, silver, lead, zinc and antimony mineralization. Geological interpretation completed over the winter has refined the structural model of the system and identified several priority targets designed to better define the geometry and continuity of interpreted higher-grade mineralized shoots.
The first drill hole of the season, GH26-12, is targeting the 1350 Zone adjacent to the Lower Rufus Adit. The hole will test the principal Rufus Vein together with interpreted mineralized structures located both above and below the vein. Drilling at the 1350 Zone will evaluate the continuity, grade, thickness and structural geometry of the mineralized system and provide critical information to guide subsequent drilling throughout the Rufus zone.
Following drilling at the 1350 Zone, the Company plans to advance testing of the 1100, 1000 and 500 Zones, targeting interpreted high-grade shoots identified from historical underground chip sampling and the Company's geological modelling which was updated following the 2025 exploration program.
Dave Nuttall, Vice President of Exploration, commented "Interpretation work of our 2025 drill season has fundamentally improved our understanding of the Greyhound Shear and, in particular, the structural controls on mineralization at Rufus. As a result, the program this season is far more targeted than in 2025. Rather than simply testing mineralization, we are now drilling specific structural positions where we believe higher-grade shoots may develop. Beginning at the 1350 Zone allows us to test our updated geological model while collecting critical information that will guide the remainder of the program."
