Capstone Mining Announces Q2 2017 Production Results

VANCOUVER, July 12, 2017 /CNW/ - Capstone Mining Corp. ("Capstone") (TSX: CS) today announced production results for the three and six months ended June 30, 2017. Combined production totalled 24,000 and 44,900 tonnes of copper in the second quarter and year-to-date periods, respectively, with additional by-products of zinc, molybdenum, lead, silver and gold.

Q2 and YTD 2017 Copper Production (tonnes)

  Q1 Q2 YTD 2017
Pinto Valley 11,300 15,500 26,800
Cozamin 4,100 4,100 8,200
Minto 5,500 4,400 9,900
Total copper production (1) 20,900 24,000 44,900
(1) Total production includes copper in concentrate and cathode production.

"All three of our mines produced according to plan in the second quarter," said Darren Pylot, President and CEO of Capstone. "Pinto Valley set new quarterly, monthly and daily throughput records after returning to full operations from the heavy rain and maintenance activities early in the year."

"Cozamin's copper production once again outperformed and Minto continued to execute a mine plan that  advances the operation towards an extended mine life into 2020 and potentially beyond," continued Mr. Pylot.

Operational Highlights

  • At Pinto Valley, throughput averaged 58,700 tonnes per day ("tpd") for the quarter, setting a quarterly throughput record as well as achieving a new monthly throughput record in May of 60,300 tpd. Grade, recoveries and production were as planned for the quarter.
  • At Cozamin, grade and recoveries were as expected, with throughput continuing ahead of plan on ongoing improvement in mine production and mine development.
  • At Minto, production for the quarter was impacted by mine sequencing changes to support a mine life extension. Throughput continued higher than planned, but head grade and recoveries were lower than planned due to a higher percentage of partially oxidized ore feeding the mill from the Area 2, Stage 3 open pit and underground mining running slightly behind schedule.

(1) Adjustments based on final settlements will be made in future periods. (2) Pinto Valley gold production reaches payable levels from time to time. Any payable gold production will be reported in the period revenue is received. At Minto, final gold production is not available since assaying is conducted off-site, but is estimated above. (3) Grade and recoveries were estimated based on concentrate production. *Silver and gold have not been estimated in the Pinto Valley resource model. Only recovered silver and payable gold is reported for this mine.

Operating Outlook

Capstone expects to be within the range of 2017 consolidated production guidance of 94,000 tonnes (±5%) of copper. Minto and Cozamin are expected to complete the year on, or above plan, largely offsetting Pinto Valley's first quarter deficit.
