  1. Length-weighted averages from uncut assays
  2. Intervals reported are hole lengths with true width estimated to be 90% or greater
  3. *Gold silver ratio used to calculate AgEq is 75 g/t Ag to 1 g/t Au
  4. 75 g/t AgEq external cut Off

To date all 12 holes for which assays have been received have intersected silver and gold mineralization using a +75 g/t AgEq external cutoff. Ten of the twelve holes were designed to test up dip or strike extensions of known structures outside of the volumes used in the historical resource estimations. Two holes have tested new targets over 2 kilometers away from the historic resource area.

Gregory K. Liller, Executive Chairman and Chief Operating Officer commented, "I am very pleased that all of the holes drilled to date have returned positive results. I find Holes TDH010 and TDH011 to be very important. The Astasis structures are essentially blind targets covered by very young basalts. A very small erosional window in a gully is the only natural exposure. I find the fact that the first two holes hit +75 g/t AgEq intercepts to be highly encouraging. Additional drilling at Astasis is currently being planned"

The Phase 2 drill program has been designed to test extensions of the previously defined breccia/vein structures, test newly defined targets and infill the existing drill pattern in order to facilitate the estimation of an updated NI43-101 compliant resource. The Tepic project is a +2,600 hectare project where the previous operator completed 149 core holes totaling more than 31,000 meters.
