The low sulfidation mesothermal gold-silver mineralization observed to date is impressive, marked by hydrothermal breccias, quartz stockworking, and stringer lode veins associated with quartz-feldspar porphyry dikes with silicification and argillic alteration. Oxidized carbonate replacement bodies and quartz stringer lode veins with silicification and argillic alteration are present in the Bisbee formation sediments. Hornfels and skarn are present within the host sediments of sandstones, siltstones and limestones. Areas of intense hematite, goethite and manganese wad are widespread, associated with better Au and Ag values. Cerargyrite (silver chloride) is observed in fractures, as often is fine-grained, visible gold. Most Au-Ag mineralized zones intersected in the drilling programs are proximal to the historic, extensive underground mine workings or the historic, shallow open pit walls.

The recent 2023, 7-hole, core drill program on the Tombstone project was successful in expanding mineralization laterally and to depth, reached the water table and the highest of the Paleozoic sediments, and connected the main and southern mineralization. Every one of the drill holes intersected near surface, oxidized gold-silver mineralization, and all the drill holes crossed multiple historic underground workings where presumably most of the highest-grade gold and silver were previously mined, indicating the main mineralized zones are still open to depth and laterally.

Updated Exploration Program

The Company will be developing the targets with multiple disciplines including continuing the surface exploration program in the area of the Contention pit with advancing the detailed geological mapping, and further out with reconnaissance level geological mapping of lithologies, Terraspec alterations and structures, multi-element rock geochemistry, and thin section petrology and alterations to review the hosting of the gold-silver mineralization. The data acquired will then be integrated into the 3D model being constructed, supporting the upcoming drilling program design.
