The East Durango project is an early stage project with gold bearing jasperoids plus quartz veins and breccias.

Trace element geochemistry indicates potential for polymetallic veins/replacements and possibly sedimentary rock hosted gold deposits.

A joint venture with Quaterra involving the Tecolote concession was entered into by EXMIN and Quaterra on September 15, 2008. Quaterra may earn up to 75% interest in the concession by paying US$100,000 over four years (US$40,000 was paid to EXMIN through September 15, 2009) and by spending US$500,000 in exploration and development work on the property by September 15, 2012. Quaterra must also maintain the property in good standing by completing the semi-annual tax payments and minimum required annual work expenditures.
