Greens Creek

At the Greens Creek mine, 2,117,024 ounces of silver were produced in the second quarter of 2016, a 14.1% increase over the 1,856,125 ounces produced in the prior year period, and 11,528 ounces of gold were produced, 16.2% lower than the 13,753 ounces in the prior year period. Increased silver production resulted from higher grades, as well as slightly higher production. Silver production is now estimated to be 8.3 million ounces and gold production slightly higher at 53,000 ounces for 2016. The mill operated at an average of 2,235 tons per day (tpd) in the second quarter.

Lucky Friday

At the Lucky Friday mine, 857,542 ounces of silver were produced in the second quarter, 39.8% higher than the 613,474 ounces produced in the prior year period. The increase in silver production was due to higher grades in the current period and ventilation repairs made in the prior year period. Estimated silver production remains at 3.1 million ounces for 2016. The mill operated at an average of 745 tpd in the second quarter.

The focus of the #4 Shaft Project, having reached its final depth of 8,600 feet below surface in early May, is on equipping the shaft with steel sets, guides, skip loading facilities and electrical infrastructure, with the goal of the shaft being fully operational in the fourth quarter of this year, and to beginning the lateral development necessary to provide access to higher-grade material.

Casa Berardi

At the Casa Berardi mine, 41,954 ounces of gold were produced in the second quarter, 35.6% higher than the 30,939 ounces produced in the prior year period. The higher gold production was principally the result of higher grades. Gold production is now estimated to be 145,000 ounces for 2016 (surface and underground). The mill operated at an average of 2,398 tpd in the second quarter.

The East Mine Crown Pillar (EMCP) pit excavation has exposed the vein closer to surface than expected; processing of EMCP ore is estimated to begin in the third quarter. The EMCP pit is expected to add 5,000 ounces of gold production in 2016.

San Sebastian

At the San Sebastian mine, 1,258,104 ounces of silver and 9,483 ounces of gold were produced in the second quarter. Production of both silver and gold was strong in the second quarter due to the prevalence of high-grade material from the East Francine Pit. Silver production is now estimated to be 4.35 million ounces, and gold production to be 35,000 ounces for 2016. The mill operated at an average of 411 tpd in the second quarter.
