Mexico’s Best Drilling Intercepts, Third Week of September 2026

/ Gambusino Prospector / Leave a comment

Four companies released results from drilling projects in Mexico during the week.

Axo Metals announced results from 29 holes representing approximately 5,000 m of drilling. These are the first resource growth and step out drilling done in the property since its acquisition by the company. The project is within the San Javier mining district in Sonora, displaying clear iron oxide copper gold (IOCG) mineralization.

Capitan Silver reported results from 35 drill holes from its 60,000 m diamond and reverse circulation drill programs at its Cruz de Plata project in Durango. The results are from the three major target areas of the Jesús María Silver Trend, expanding known mineralization to 2.8 km. “The remainder of the 60,000 m program for this area is focused on drilling the strike length of the Jesus Maria Silver Trend to a depth of 500 m vertically from surface with down-dip step outs increasing to 80 to 175 m with diamond drilling. The RC rig is now fully dedicated to drilling newly-permitted targets”. The Jesús María zone presents intermediate sulfidation epithermal mineralization, while the gold resource at Capitan Hill is in a low sulfidation epithermal system.

Kootenay Silver reported assay results from  expansion drilling along the D vein at its Columba project in Chihuahua. “The current exploration work comprises a phased 60,000-metre drill program focused on expanding the resource detailed in the Company’s recent NI 43-101 Mineral Resource Estimate”. Columba contains mineralization with intermediate sulfidation epithermal characteristics.

Americas Gold and Silver announced drill results from the ongoing resource conversion drilling program at the Coslá Complex in Sinaloa. “The assays released are a result of infill and step-out drilling conducted in 1H 2026 at the San Rafael Upper, 120 Upper and 120 Lower deposit”. Mineralization at the property includes exoskarn, endoskarn, carbonate replacement (CRD), mantos and chimneys.
