Capstone Reports Production Results for the First Nine Months of 2010
VANCOUVER, October 5, 2010 /PRNewswire-FirstCall/ --
- Year-to-Date Production of 58.0 Million Pounds of Copper in Concentrates
Capstone Mining Corp. (CS: TSX) today announced its operating results for the three and nine months ended September 30, 2010 from its two operations, the Cozamin and Minto mines. Combined production totalled 19.2 million and 58.0 million pounds of copper in concentrates in the third quarter and first nine months, respectively, with additional significant by- products of lead, zinc, silver and gold. At September 30, 2010 Capstone had a cash balance of US$170 million (including restricted cash of US$11 million and a short-term deposit balance of US$20 million), a significant increase primarily attributable to the cash generated from sales at higher metal prices as well as the sale of some investments. Full financial results will be reported on November 9, 2010, as discussed below.
As previously disclosed, operational performance has improved at both the Cozamin and Minto mines during the course of the third quarter of 2010. Mining rates at Cozamin continued to improve through September, with higher copper grades reporting to the mill as well. Minto's tailings filter plant performance continues to restrict mill throughput, but to a lesser degree than experienced previously, as improvements to the tailings filtration circuit have begun to take effect. Results at both operations are in line with mid-year revised guidance and full year guidance remains unchanged at 80 to 85 million pounds of copper in concentrates.

(x) Minto realized negative adjustments to previously reported copper
production based on the final settlement of copper sales during the
first six months in the amount of one million pounds. As these
amounts are related to shipments made over the first six months, but
relate to production in the latter part of 2009 and early 2010, the
adjustments are only reflected in the year to date column, therefore
certain lines will not sum across.
These operating results have been provided earlier than normal in order to accommodate an investor and analyst tour of Capstone's mines taking place October 4-8, 2010 and, as a result, do not contain operating cost information, which will be included in Capstone's financial reporting for the third quarter, 2010.
Operational Highlights for the three and nine months ended September 30, 2010
The following is a summary of operational highlights for Capstone during the three and nine months, respectively, ended September 30, 2010:
- Production of 19.2 million and 58.0 million pounds of copper
contained in concentrates, respectively.
- By-product production of 6.0 million and 13.7 million pounds of
zinc, 1.8 million and 7.6 million pounds of lead and 427,289 and
1,225,357 ounces of silver in concentrates, for the three and nine
months, respectively. Final gold production is not available since
assaying is done off site, but is estimated at 4,788 and 18,156
ounces for the respective periods.
- Detailed operating statistics for both operating mines are provided
in the tables below.

(2) Adjustments based on final settlements will be made in future periods
- Mined tonnes and milled tonnes were essentially at design levels for
the full quarter.
- However, as previously disclosed, mine production increased around
mid-August and, since then, mine and mill production tonnage have
averaged approximately 3,400 tonnes per day, well above the mill
design capacity of 3,000 tonnes per day.
- Average copper grade for the quarter remain lower than indicated in
prior guidance due to the previously disclosed reduced production
from the high copper grade, wider Avoca stopes. In September, copper
grades increased as production in the Avoca zone increased following
completion of the additional cable bolting recommended by the
Company's geotechnical consultant.
- Copper grades for the fourth quarter are expected to increase and
lead grades be lower than has been the situation so far in 2010 as a
result of increased production from the Avoca area and less reliance
on the upper and hangingwall workings, where zinc, and especially
lead, grades are higher than is typical for the overall mineral
reserves.
- Full year guidance remains unchanged at Cozamin for 40-42 million lbs
of copper.

(2) Gold is not assayed on site, resulting in a significant lag in
receiving this data. Data for Q3 is an estimate based on prior
production experience.
(3) Adjustments based on final settlements will be made in future
periods.
(4) Adjustments are only reflected in year to date column relating to
negative adjustments of previously reported copper production.
- Improvements in the tailings filtration plant resulted in
significantly improved mill throughput compared with the second
quarter, following completion of rebuilds of three of the five
filters, with two more rebuilds to be completed in October.
Cumulative throughput remains below guidance for the year.
- August and September mill throughput averaged over 2,700tpd compared
with just over 2,000tpd in the second quarter following the
improvements in tailings filtration noted above.
- Throughput is expected to further increase with installation of
higher performance filter cloths in the tailings filters during
October and November.
- No ore was mined from the pit during the third quarter due to the
continued presence of water in the Minto Main pit that was either
collected during freshet or resulted from relatively high rainfall
in late-July and August and which was not discharged at that time in
order to ensure compliance with Minto's water use licence. Minto has
applied for and is working through the regulatory process to amend
its water licence standards to improve overall water management
while remaining protective of the environment.
- The inability to mine high grade ore from the Stage 4 push-back of
the Minto Main pit adversely affected the copper grade in the third
quarter as operations were reliant on previously stockpiled ore with
no supplementary higher grade ore from the open pit.
- The new water treatment facility has been on line and treating and
discharging water since July 2010. Mining is expected to recommence
from the Stage 4 push-back in late October following removal of the
remaining water from the pit.
- The delays in dewatering the Minto Main pit were anticipated in the
mid-year forecast and full year guidance remains unchanged at 40-43
million lbs of copper.
Forward Sales
Capstone continues to reduce its forward copper sales commitments through a combination of deliveries of metal produced at its mines and entering into offsetting forward copper purchase contracts that increase Capstone's exposure to rising copper prices. During the quarter Capstone reduced its net forward sales obligations by more than 50% versus the net positions on June 30, 2010. The market to mark of the Company's hedge book will be reflected in Capstone's future financial statements. The Company's net forward copper sales contracts at September 30, 2010 are tabulated below.
