(1) Gold equivalent ounces ("GEO") and grades are computed as the applicable gold ounces/grade plus the silver ounces/grade divided by a GEO ratio. GEO ratios are computed by dividing the average realized gold price per ounce by the average realized silver price per ounce received by the Company in the respective period. Preliminary Q2 GEO ratios were approximately 75.3:1 for Fire Creek, 76.1:1 for Midas, and 75.4:1 for Total. For the six month period ended June 30, 2016, preliminary GEO ratios were approximately 77.0:1 for Fire Creek, 76.5:1 for Midas, and 76.1:1 for Total.

The progressive increase in GEO production during the second quarter of 2016 was primarily due to an increase in tons mined and milled. Average gold equivalent mill head grades at Fire Creek improved from the first quarter as the Company returned to mining higher grade zones. Average gold equivalent mill head grades improved slightly at Midas due to mine sequencing. The Company continues to expect the mill head grades at Midas to progressively increase throughout the year. Average silver recovery rates were slightly lower than expected due to higher mill throughput, which reduced ore retention time in the leach tanks.
