Three companies published results from drilling campaigns in Mexico during the week.

Kootenay Silver released results from nine holes drilled at its Columba property in Chihuahua. The project has a mineral resource estimate comprising 5.92 M tonnes averaging 284 gpt Ag. The current drill program is focused on the expansion of the resource, as orebodies remain open in all directions, and is testing extensions to the D Vein and the Lupe B2 trend structures at 100 m spacing. The next is an excerpt of the technical report: “Mineralization at Columba occurs in veins with mineralogical characteristics and alteration assemblages typical of low to intermediate sulfidation epithermal deposits. Mineralization styles observed on the Property can be broadly categorized as: (i) primary banded quartz ± calcite ± barite mid-low sulphidation epithermal veins; (ii) quartz ± barite ± haematite vein and veinlet stockwork breccia in hanging wall rhyolite associated with argillic alteration of the wall rock; and (iii) silicified hydrothermal breccia near lithological contacts.

At Southern Silver Exploration’s Cerro Las Minitas in Durango, the ore bodies are associated with the intrusion of a monzonitic to quartz monzonitic stock into a sedimentary sequence that produced skarn and carbonate replacement (CRD) style alteration and mineralization in skarnoid, chimney, manto, and dyke margin bodies. In the case of Las Coloradas, in Chihuahua, the technical report does not specify the mineralization style, but the descriptions point to a likely intermediate sulfidation epithermal affinity, a common assemblage in the Parral region where it is located.
