Mexico’s Best Drilling Intercepts, Second Week of April 2024

/ Gambusino Prospector / Leave a comment

Three companies released drilling results during the week coming from projects in Mexico: Pan American Silver on La Colorada Skarn in Zacatecas, Prime Mining on Los Reyes in Sinaloa and Goldgroup Mining on Cerro Prieto in Sonora.

Pan American Silver’s impressive grade*meter numbers on silver, lead and zinc come from the ongoing infill and geotechnical drill program at La Colorada Skarn project, adjacent to its La Colorada property, where they are mining an intermediate sulfidation vein system. Prime Mining’s results are from Expansion drilling on the Tahonitas area at Los Reyes, where the company believes the early-stage intersections demonstrate the Tahonitas structure continues to be mineralized for 350 m along strike and may support pit expansion to the southeast near surface, as well as an increased potential for high-grade plunging shoots that might provide “high-margin underground feed”.

The newcomer on this weekly review is Goldgroup Mining, with results from 2023 drilling at its Cerro Prieto mine in Sonora. Cerro Prieto is within 10 K from Agnico Eagle’s Santa Gertrudis project and even closer from Sonoro’s Cerro Caliche project. Cerro Caliche is a low sulfidation system hosted in Tertiary volcanic rocks and Triassic-Jurassic sedimentary rocks intruded by an Eocene granodiorite stock, whereas mineralization at Santa Gertrudis includes disseminated gold in sedimentary rocks that has been described as Carlin-Style and/or low sulfidation epithermal, and clear low sulfidation quartz stockworks and veins. At Cerro Prieto, mineralization developed in a shear zone up to 65 m in width. Unfortunately the description of the local stratigraphy for Cerro Prieto on their last technical report (2023) comes at odds with the published government maps and include some bizarre descriptions for at least one of the units. Mineralization is interpreted by Goldgroup to have come in two stages, an early mesothermal one that would attest for the Pb, Zn and Mo grades and a later low sulfidation epithermal that would introduce the higher gold values and the silver. The old Cerro Prieto mine was one of the type localities for wulfenite (PbMoO4).

Mexico’s Best Drilling Intercepts, First Week of November 2023

Regency Silver was the only company to release drilling results from a project in Mexico during the week, with interesting gold, copper and silver numbers. The Dios Padre property is in the Santa Rosa de Yecora district, which hosts several ore deposits in breccia bodies within a batholith or in its contact with volcanic rocks, like some other projects in the area.

Speaking of the Santa Rosa de Yecora district, this week also Atacama Copper released a Cu-Ag-Mo maiden resource estimate for its Yecora project, which is adjacent to the Santana gold project currently being mined by Minera Alamos, and is also adjacent to the historically known Los Verdes Mo-Cu deposit. A few kilometers to the East is the Mercedes project (formerly La Lamosa), which was drilled last year by Magna Gold and holds a small (non NI-43-101 compliant) gold resource. Several other projects, like Potrerillos, Tía Cantuna and Santa Rosa (drilled by Centerra) are also related to breccia bodies or the batholith contact with the hosting volcanic rocks.

According to the technical report released by Regency early in 2023, the silver deposit at Dios Padre is of low sulfidation epithermal affinity. In the last press release the picture emerging is more according to the district mineralization, with an early gold-silver mineralization related to a pyrite-specularite breccia and copper mineralization increasing with depth to a quartz-feldspar porphyry. The Santa Rosa de Yecora District is likely to have more significant mineralization to be found.
