A dozen companies reported during the third quarter silver intercepts from drilling campaigns in Mexico. The best results by a fair margin were those from Vizla Silver, from its Panuco project in Sinaloa. All the projects in this list are in Sonora, Chihuahua Sinaloa and Durango, in the coastal plains of NW Mexico, the Sierra Madre and the Altiplano regions (check here the Mining Regions of Mexico: https://gambusinoprospector.com/mineral-resources-in-mexico/mining-regions/).

Most of the projects that report silver values in Mexico are epithermal deposits of low and intermediate sulfidation affinity. Seven of the eleven projects on the list below, Panuco, Columba, Copalquin, El Tigre, Los Reyes, Navidad and Cerro Los Gatos fall in those two categories. Three more, Alamos, Cristina and Pilar, present epithermal characteristics, but bear copper values and are in the vicinity of porphyry copper systems. Conventional wisdom calls these intermediate sulfidation, but probably is a good idea to separate these, as in most cases intermediate sulfidation deposits in Mexico can not be tied to porphyry copper mineralization. La Parrilla is described as a carbonate replacement deposit with local skarn and intermediate sulfidation mineralization.
