San José Mine, Argentina (49% ⁽²⁾ ) – Improving Production

Our attributable production from San José in Q2 was 12,477 gold ounces and 774,521 silver ounces, for a total of 22,804 gold equivalent ounces. During the first half of 2017 our attributable production was 42,729 gold equivalent ounces, a slight improvement on the same period in 2016, mainly driven by better gold grades.

El Gallo Mine, Mexico – Grade to Increase in Second Half

Production in Q2 was 9,780 gold equivalent ounces, compared to 15,640 gold equivalent ounces during the same period in 2016. Production in the first half of 2017 was expected to be slower as a result of lower gold grades mined, however gold grades are projected to increase in the second half of the year.

Timmins Projects, Ontario, Canada

Evaluation work and trade-off studies are underway to determine in which order the newly acquired properties will be advanced towards development. Updated resource estimates are expected later this year.

Financial Results

Operating costs for the quarter ended June 30, 2017 will be released with our 10-Q Quarterly Financial Statements in early August. As at June 30, 2017 we are debt-free with liquid assets of $44 million comprised of $24 million in cash, $8 million in precious metals, and $12 million in marketable securities. Substantial investments in our Los Azules project and lower production levels from our El Gallo Mine contributed to the reduction in liquidity since Q1. We have not issued equity to finance our operations since completing a rights issue in 2013, and we have preserved our leverage to higher gold and silver prices by not encumbering our assets with royalties, metal streams or hedges.
