Vancouver, British Columbia – Capstone Mining Corp. (“Capstone”) (TSX: CS) announced production results for the three and nine months ended September 30, 2018. Combined production totalled 21,400 and 60,600 tonnes of copper in the third quarter and year-to-date periods, respectively, with additional by-products of zinc, molybdenum, lead, silver and gold.
Q3 and YTD 2018 Copper Production (tonnes)
Q1 | Q2 | Q3 | YTD 2018 | |
Pinto Valley | 11,400 | 13,400 | 14,200 | 39,000 |
Cozamin | 4,300 | 3,500 | 4,400 | 12,200 |
Total copper production from continuing operations (1) | 15,700 | 16,900 | 18,600 | 51,200 |
Minto | 3,500 | 3,100 | 2,800 | 9,400 |
Total copper production (1) | 19,200 | 20,000 | 21,400 | 60,600 |
(1) Total production includes copper in concentrate and cathode production.
“Pinto Valley performed as expected in the third quarter, with planned higher grade feeding the mill as scheduled,” said Darren Pylot, President and CEO of Capstone. “Cozamin’s copper production was higher than projected and zinc production rose considerably. We remain on track to meet our consolidated copper production guidance from continuing operations for the year.”
Operational Summary
- At Pinto Valley, production increased in the third quarter on planned higher grade. Throughput rose from the second quarter due to more stable operations and steadily improving availability in the crushing and milling circuits, as the asset reliability project continues to advance.
- At Cozamin, copper production for the quarter increased on higher grade and throughput. Mine output increased over the previous quarter as production from the San Rafael zinc zone ramped up to planned levels by mid-quarter, resulting in the highest quarterly zinc production in over five years.
- At Minto, the revised mine plan produced 2,800 tonnes of copper for the third quarter. The asset continues to be classified as a discontinued operation held for sale.

(1) Adjustments based on final settlements will be made in future periods. (2) Silver and gold at Pinto Valley and gold at Minto are not assayed on site, resulting in a significant lag time in receiving this data. As such, these figures are estimates and for Minto includes gold contained in copper concentrate and gold contained in gold concentrate produced. (3) Pinto Valley gold production reaches payable levels from time to time. Any payable gold production will be reported in the period revenue is received. (4) Grade and recoveries were estimated based on concentrate production and may be impacted by settlements from prior production periods. *Silver and gold have not been estimated in the Pinto Valley resource model. Only recovered silver and payable gold is reported for this mine. (5) YTD 2018 includes a negative 28 ounce adjustment made in Q3 2018 related to Q2 2018 gold sales for which final settlement was made in Q3 2018.
Operating Outlook
Capstone’s 2018 consolidated copper production guidance for Pinto Valley and Cozamin remains unchanged at 71,000 tonnes (+/-5%).
