VANCOUVER, April 26, 2011 /PRNewswire-FirstCall/ --
- First Quarter Production of 16.7 Million Pounds of Copper in Concentrates
Capstone Mining Corp. (TSX: CS) today announced its operating results for the three months ended March 31, 2011 from its two operating mines, Cozamin and Minto. Combined production totalled 16.7 million pounds of copper in concentrates, with additional by-products of lead, zinc, silver and gold.
Q1 2011 Production Q1 2011 Copper in concentrates (millions of pounds) - Cozamin 8.6 - Minto 8.1 Total 16.7
Operational Highlights for the three months ended March 31, 2011
The following is a summary of operational highlights for Capstone during the first three months of 2011:
- Production of 16.7 million pounds of copper contained in concentrates.
- By-product production of 4.2 million pounds of zinc, 0.8 million pounds of lead and 367,704 ounces of silver in concentrates. Final gold production is not available since assaying is done off site, but is estimated at 2,925 ounces for the quarter.
- At Cozamin, remediation activities in the mine curtailed mining rates throughout the first quarter. By mid-March most of these activities were completed and mining commenced in the Avoca area at the end of March, which is expected to contribute to higher productivity and grades throughout the remainder of the year.
- At Minto, production was at low levels in the first quarter due to a combination of lower mill throughput and lower grades.
- The lower grades at Minto were due to a high grade ore shortfall in Stage 4 of the Main Pit, resulting in processing less high grade material than planned. While insignificant in overall volume of ore in the Main Pit, the decrease in grade negatively impacted metal production for the quarter. Mining during the first quarter was focused on mining the final stage of the Minto Main Pit (Stage 5) before freshet where ore grades have been consistent with plan. Mining of the Main Pit is now substantially completed.
- Steady improvements to SAG mill throughput were made through the first quarter. To assist with increasing throughput, additional crushing capacity has been implemented through contract crushing, which began in mid-April to remedy the throughput shortfall until design crushing changes are implemented, expected late in the third quarter of 2011.
- Minto received the amended water use license in late March. Once implemented, the revised license is expected to facilitate improved water management at Minto during freshet. Application for the subsequent water use license amendment, which will permit tailing discharge into the mined out Main Pit, will be submitted by mid-May.
- The environmental and socio-economic evaluation for the Phase IV expansion was completed and a decision document was issued recommending that the project proceed. A temporary amendment to the current Quartz Mining License was issued in March which allows stripping to begin for Area 2 mining and development of the underground portal.
- Pre-stripping has commenced in Area 2 at Minto following completion of mining the remaining ore in the Main Pit. A new Quartz Mining License at Minto is anticipated in the second quarter that will permit the long-term development of Area 2.

Outlook
Despite low production for the first quarter, Capstone is maintaining full year 2011 guidance of 80-85 million pounds of copper in concentrates. At Cozamin, production is expected to ramp up quickly from first quarter levels now that mining has recommenced in the Avoca area. At Minto, contract crushing commenced on April 15, increasing throughput rates to a level that is expected to allow production to proceed as planned for the remainder of the year.
Q1 Financial Results Timing
Q1 financial results are expected to be reported in late May or early June 2011 and will be announced with conference call details once scheduled.
