  • Increased Proven and Probable mineral reserves at La Yaqui Grande to 644,000 ounces of gold, (14.3 mt grading 1.40 g/t Au) a 24%, or 123,000 ounce increase.  Including additions within the Mulatos Pit, this offset mining depletion at Mulatos
  • Initial Proven and Probable mineral reserve declared at Lynn Lake of 1.6 million ounces of gold (26.8 mt grading 1.89 g/t Au) with the release of the positive feasibility study in December 2017
  • Global Measured and Indicated mineral resources decreased 21% to 7.4 million ounces of gold, (207 mt grading 1.1 g/t Au) reflecting the conversion of mineral resources to mineral reserves at Lynn Lake
