Silver Storm was the only company to release drilling results from a project in Mexico on the first week of the year. La Parrilla mine complex is in Durango, “comprised of a 2,000 tpd mill as well as five underground mines and an open pit that collectively produced 34.3 million silver-equivalent ounces between 2005 and 2019”.

From the last technical report, La Parrilla district contains intrusion-related carbonate replacement deposits and mesothermal fault-veins hosted by Early Cretaceous limestones and shales that have been intruded by an Eocene quartz monzonite-granodiorite stock which metamorphosed the Cretaceous rocks into marble, hornfels, skarnoid and minor skarn. La Parrilla deposits contain primary sulphides such as galena, sphalerite, pyrite, pyrrhotite, arsenopyrite, chalcopyrite, covellite, acanthite, native silver, and silver sulphosalts.
