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

Greg Liller, Chief Operating Officer states, “The trenches continue to deliver strong gold results in the main structures and the broad zones of more moderate gold grades are very encouraging for the development of a larger project.”

In addition, LTZ02 was extended to the east as previous sampling began in gold mineralization. Additional moderate gold grades are present in the trench extension resulting in a combined length of 37.7 meters grading 0.37 gold, 3 g/t silver for a AuEq grade of 0.38 g/t.
