Metallis Resources Inc. Advances Geological Interpretation of Greyhound Shear and Refines Targeting Model for 2026 Drill Program
Metallis Resources Inc. provided an update on its ongoing technical review and reinterpretation of the Greyhound Silver-Gold-Antimony Project in Idaho, USA. Following the completion of the 2025 drill program, the Company has undertaken a comprehensive evaluation of geological, geochemical, and historical underground data to further refine its exploration model and identify priority drill targets for the 2026 field season. The Company's updated interpretation builds on a strong foundation of historical exploration and recent drilling. By integrating legacy underground data with modern 3D modelling and recent surface and drill results, Metallis has enhanced its understanding of the structural controls on mineralization and the distribution of higher-grade zones across the Project. The updated geological interpretation represents an important step forward in understanding how mineralization is distributed at Greyhound and helps explain the variability observed in the 2025 drill results. By pulling historical underground information, recent drilling and surface sampling into 3D space, the team has developed a clearer picture of the geometry of the mineralized system and where higher-grade concentrations of silver, gold, lead, zinc, and antimony are most likely to occur. This improved understanding allows more precise targeting of the high-grade portions of the system as the 2026 drill program is planned. Multiple priority target areas have been identified along the 3.5 km trend, along with new geochemical anomalies that suggest the system may extend beyond what was previously recognized. With a strengthened geological model and more clearly defined targeting criteria, the company is entering the upcoming season with increased confidence in the scale of the opportunity and the potential to continue building long-term value at Greyhound. Refined vein models indicate the Greyhound shear system comprises multiple southwest-dipping shear veins, improving understanding of vein geometry and structural controls on high-grade mineralization. Ore shoots are interpreted to be associated with dilation zones related to cross-cutting faults, structural bends, and pre-mineral dyke contacts. Reinterpreted soil geochemistry outlines new anomalies and suggests the Greyhound trend may extend north and northwest beyond the currently defined 3.5 km strike extent. A 2026 drill program of approximately 3,000 m is planned, focused on high-grade shoots within the Rufus Zone, and surface mineralization at Birdie, Bulldog, and Idaho. The technical review has resulted in a meaningful advancement in the Company's understanding of structural controls on mineralization at Greyhound. Using the historical underground surveys of the Lower and Upper Rufus adits, Metallis has identified and corrected spatial inaccuracies in the historical dataset georeferencing, which previously placed the adits 30 m northeast of the corrected locations. This work has led to a revised interpretation of the main Rufus shear zone, which is now understood to dip steeply to the southwest rather than to the northeast as previously modeled. This updated structural framework is supported by results from drill holes completed in 2025. Holes GH-25-05, -06, and -07 did not return grades and widths consistent with the high-grade shoots identified in historical underground chip sampling, however the holes successfully intersected the shear zone and support a southwest dip orientation. Importantly, these holes also identified additional adjacent veins carrying elevated silver, gold, lead, zinc, and antimony values within an envelope measuring 30-40 m wide, revealing a broader, multi-vein mineralized system than previously interpreted. While hole GH-25-07 intersected the primary Rufus vein, it is interpreted to have tested a portion of the vein system outside of the higher-grade shoots identified in historical underground workings, where average grades above 400 g/t Ag and 1 g/t Au are seen. Comparison of the intercept from hole GH-25-07 (94.76 g/t Ag and 0.34 g/t Au over 15.45 m; 3-4 m true thickness) with underground chip sampling indicates that the grades encountered are more consistent with mineralization between higher-grade shoots, reinforcing the importance of structural controls in localizing high-grade zones. Building on this work, Metallis has developed a new 3D geological model of the Greyhound system extending from surface to approximately 300 m depth. Within this model, the Company has identified priority high-grade shoot targets along the Rufus shear zone, including the 500, 1000, and 1350 zones. These targets represent sub-vertically oriented mineralized shoots linking historical underground workings with surface geochemical anomalies and mapped vein exposures. At the Rufus Zone, high-grade shoots -- characterized by increased vein thickness and elevated Au, Ag, Pb, Zn, and Sb -- are interpreted to be spatially associated with cross-cutting faults, local changes in shear orientation, and pre-mineral dyke contacts. Documentation of these features in historical underground mapping has enabled improved constraint of shoot geometry and represents an important advancement in drill targeting. Planned drill holes oriented to the northeast will be designed to intersect these interpreted ore shoot corridors within the multi-vein Rufus shear zone. Depth extent provides a key driver of exploration potential at Greyhound. Surface and underground sampling indicate anomalous Au, Ag, and Sb mineralization over a vertical extent of at least 600 metres between mineralized outcrops at the Ridge Cut and General Grant showings. The implied vertical continuity, combined with a 3.5 km strike extent, supports potential for a vertically and laterally extensive mineralized system. The refined model highlights compelling targets for testing down plunge of the 1350, 1000, and 500 zones, as well as below underexplored zones along trend, including Idaho, Akita, Bulldog, Republican, and Birdie. A re-evaluation of 2024 soil geochemistry using zinc as a pathfinder element -- based on its strong correlation (r = 0.75; n = 536) with silver in rock samples -- successfully delineates all known mineralized zones, including General Grant, Birdie, Rufus, Idaho, Bulldog, Akita, and Republican. A significant new anomaly measuring approximately 900 by 600 m has been identified north of the Republican zone. This anomaly is comparable in size to the footprint of the Rufus soil anomaly, which encompasses collectively the Rufus, Birdie, and General Grant showings, and it is located off axis from the main trend, potentially reflecting a structural dilation zone where the shear trend may bend toward the north. This previously untested area represents a compelling new target and will be prioritized for trenching, mapping, and sampling in 2026. The Company also plans to extend the soil grid to the north and northwest to fully define the extent of this anomaly.
