SAN JAVIER DE COBRE PROJECT
About the Project
The San Javier property is in central Sonora, Mexico, approximately a two-hour drive (125km) east of the capital city of Hermosillo (population ~800,000) along National Highway 16 and approximately a six-hour drive from Barksdale’s projects in southern Arizona. The property consists of twelve separate mineral concessions totaling approximately 1,184 hectares, upon which multiple zones of copper mineralization have been identified to date. The project is positioned with significant logistical advantages as Cerro Verde, the main mineralized zone, is located less than 1km from a paved highway as well as the national power grid. Multiple companies have previously explored and drilled within the San Javier property position, including Servicios Industriales Peñoles S.A. de C.V., Phelps Dodge, Outukumpu Oyj and Constellation Copper. Notably, the San Javier property has not been actively worked since 2007. Approximately 30,000 meters of drilling has been completed to date in three separate zones, two of which contain historic resource estimates which Barksdale believes can be expanded significantly. Mineralization at Cerro Verde, the most densely drilled zone (90% of historic drilling), consists of structurally controlled hydrothermal breccias, stockworks, and veins that have intense specular hematite associated with copper mineralization. The mineralization has been characterized by previous operators as typical of an iron-oxide-copper-gold (“IOGC”) system, which generally exhibit structurally controlled mineralization. Previous exploration activity was focused on delineating near-surface oxidized mineralization, for the purpose of bulk mining. Hence, the structurally controlled high-grade mineralization that was encountered was never adequately followed-up on and thus represents a significant opportunity for Barksdale. Additionally, gold-dominant oxide mineralization as well as copper-gold sulfide mineralization has been encountered historically and requires additional investigation.

They are presented solely to provide an indication of the potential extent of the mineralization at San Javier and as a guide to future exploration.
