San José Mine, Argentina (49%)(1)

The San José Mine produced 12,527 gold ounces and 909,017 silver ounces attributable to us in Q3, for a total of 24,647 gold equivalent ounces. Year-to-date the San José Mine produced 33,839 gold ounces and 2,443,527 silver ounces attributable to us, for a total of 66,419 gold equivalent ounces. Full year production guidance for San José in 2016 is 45,000 gold ounces and 3.3 million silver ounces, for a total of 89,000 gold equivalent ounces attributable to us.

El Gallo Mine, Mexico (100%)

The El Gallo Mine performed as expected in Q3, producing 11,849 gold equivalent ounces. Production in Q3 was lower than the prior quarter due to lower ore grades, as we previously forecast (1.4 gpt in Q3 2016 vs. 2.3 gpt in Q2 2016). Year-to-date the El Gallo Mine produced 47,590 gold equivalent ounces. Full year guidance for El Gallo is 55,000 gold equivalent ounces.

Mexico Exploration Update

The 2016 exploration budget for Mexico is $4 million. Exploration drilling in the district around our El Gallo Mine has been concentrated primarily on three prospective areas; one area called Encuentro South has returned particularly encouraging results at shallow depths. Highlights are summarized below:

Hole ID Gold Grade
Width (m)
ENX-032 9.59 9.1
  including 126.50 0.5
  and 2.94 38.2
  including 27.3 1.2
ENX-043 7.82 5.4
   including 28.70 1.1
ENX-009 16.09 2.1
ENX-041 16.27 1.9
ENX-051 1.30 19.5
  and 6.13 4.8
ENX-019 1.85 15.2
  including 3.99 5.0
ENX-021 1.66 12.7

Encuentro South is located 7 miles (11 km) southwest of the El Gallo Mine. The project area lies on an important 4 mile (7 km) long, regional NW-SE mineral trend that also hosts two of our other exploration targets (Las Milpas and Twin Domes). Extensive exploration along this trend has identified favorable alteration signatures and abundant anomalous gold and silver mineralization in surface rock and soil samples.

A total of 51 core holes (8,980 meters) have been drilled in the project area, with 42 of those (7,522 meters) at the Encuentro South prospect. Initial interpretations indicate that the favourable gold assays occur in at least three distinct zones that are either shallow dipping NW, or sub-vertical NS structures and are still open along strike and at depth. Mineralization has been identified from surface to a depth of 130 meters. The known length (or strike) of the zone is approximately 230 meters. For full results of the recently drilled holes at Encuentro South see Table 1 here:

Mineralisation at Encuentro South is characterized primarily by structurally controlled, multi-event quartz breccias and stockwork zones hosted by propolytically altered meta-andesites. Minor silicification and hematisation alteration is also seen locally. The mineralization is considered to be of the low-sulphidation, epithermal style as seen elsewhere on the property. Very early stage test results show that the gold mineralization at Encuentro South is potentially amenable to heap leaching.

Financial Results

Operating costs for the quarter ended September 30, 2016 will be released with our 10-Q Quarterly Financial Statements in early November. As at October 7, 2016 we have no debt and liquid assets of $61 million composed of $39 million of cash, $18 million of precious metals, and $4 million of marketable securities. 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.

Samples from the core drilling were split on-site at the Company’s El Gallo Mine. One half of the split drill core is shipped to ALS Chemex for sample preparation and analysis by fire assay for gold and 4-acid digestion with ICP determination for silver.  Samples returning greater than 10 ppm gold or 1500 ppm silver were re-analyzed using gravimetric fire assay. Standards and blanks were inserted every 20 samples. All holes were drilled with HQ bits and reduced to NTW where required.  Samples were taken based on lithologic and/or mineralized intervals and vary in length. The true width of the mineral zones has not yet been determined.
