VANCOUVER, October 6, 2011 -

Third Quarter Production of 20.6 million pounds of Copper in Concentrates

Capstone Mining Corp. (TSX: CS) today announced its operating results for the three and nine months ended September 30, 2011 from its two operating mines, Cozamin and Minto. Combined production totalled 20.6 and 58.5 million pounds of copper in concentrates in the third quarter and first nine months, respectively, with additional by-products of lead, zinc, silver and gold.

“Both of our mines achieved record throughput levels this quarter,” said Darren Pylot, President and CEO of Capstone.  “With these higher throughput levels and additional throughput planned at Cozamin in the fourth quarter, we remain on target to meet our full year 2011 guidance of 80-85 million pounds of copper in concentrates,” continued Mr. Pylot.

Operational Highlights for the three and nine months ended September 30, 2011

The following is a summary of operational highlights for Capstone during the three and nine months, respectively, ended September 30, 2011:

  • Production of 20.6 and 58.5 million pounds of copper contained in concentrates, respectively.
  • By-product production of 5.5 and 14.2 million pounds of zinc, 1.0 and 2.7 million pounds of lead and 441,731 and 1,289,127 ounces of silver in concentrates, respectively.  Final gold production is not available since assaying is conducted off-site, but is estimated at 5,111 and 14,548 ounces for the respective periods.
  • At Cozamin, mining productivity continued to improve in the third quarter, resulting in both record ore mined for the quarter and record average mill throughput of 3,215 tonnes per day.
  • Milled ore grade at Cozamin was slightly lower than the previous quarter due to the areas mined.  Grade is expected to increase in the fourth quarter as full production is planned from the higher grade Avoca area.
  • At Minto, mill throughput continued above expectations due to the successful implementation of pre-crushing for the SAG mill feed. Throughput exceeded the previous quarterly record, averaging 3,729 tonnes per day in the third quarter.
  • Minto copper recovery was lower in the quarter due to quantities of oxide ore mixed in portions of the low-grade stockpiles.  Modifications in the flotation circuit are increasing the recovery on this material and are expected to increase recovery on the partially oxidized material that will be processed in the fourth quarter.
  • Milled ore grade continued to decline at Minto as remaining stockpiled high-grade sulphide ore was largely consumed.  Grades will increase slightly in the fourth quarter as higher grade stockpiles of partially oxidized ore are blended into the mill feed.

(1) Adjustments based on final settlements will be made in future periods.


Capstone reaffirms full year 2011 production guidance.  With year to date production of 58.5 million pounds of copper in concentrates and both mines presently operating on plan, the expectation is that production will reach 80 million pounds for the year.  In the fourth quarter, production at Cozamin is expected to be at, or above, third quarter levels as the mine plan calls for higher grade ore.  At Minto, the successful contract pre-crushing will continue until permanent improvements are implemented, and continuing high throughput is expected to offset the processing of lower grade material from stockpile.
