Capstone Reports Production & Operating Costs for Q4/09 & Full Year 2009
VANCOUVER, February 2 /PRNewswire-FirstCall/ --
- 2009 Production of 90m lbs of Copper in Concentrates at an Estimated Total Cash Cost(1) of US$1.03 per lb of Payable Copper
Capstone Mining Corp. (CS: TSX) today announced its operating results for the three and twelve months ended December 31, 2009. Combined production totalled 24.7 million and an adjusted 90 million pounds of copper in concentrates for the three and twelve months ended December 31, 2009, with additional significant by-products of lead, zinc, silver and gold. The total cash costs(1), net of estimated by-product credits and selling costs, were US$1.04 and US$1.03 per pound of payable copper produced in the three and twelve months ended December 31, 2009, respectively.
"Strong fourth quarter operating results resulted in an adjusted 90 million pounds of copper in concentrates at a total cash cost of US$1.03 per payable pound of copper during 2009, helped by a return to normal operations at both mines in the fourth quarter," said Stephen Quin, President & COO of Capstone Mining Corp. "Our mining operations in the Yukon and Mexico are well positioned to meet their objectives for 2010, and both operations have some excellent opportunities to further optimize and enhance their performance," he said. "In addition, our land holdings surrounding each of our mines have excellent exploration potential and will be the subject of sustained exploration during the year as we look to realize on that potential."

(2) Minto's operating costs are adjusted to exclude mining of ore and
waste not related to concentrate produced in the period, these costs
are capitalized or inventoried in the financial statements, then
expensed when the associated ore is processed.
Both mines realized negative adjustments to previously reported copper production based on the final settlement of copper sales during the year, 1.0 million pounds at Minto and 0.7 million pounds at Cozamin. As these amounts are related to adjustments to shipments made over the full year, the adjustments are only reflected in the year to date column, therefore certain lines will not sum across.
Operational Highlights for the three and twelve months ended December 31, 2009
The following is a summary of Capstone's operational highlights for the three and twelve months ended December 31, 2009:
- Production of 24.7 million and 90 million pounds of contained copper
respectively, with the quarterly production reflecting a return to
more typical operating parameters, while the annual numbers reflect
the coincident low production cycles at both mines during Q3/09 and
the negative 1.7 million pound adjustment related to final sales
settlements applicable to shipments over the whole year.
- By-product production of 4.7 million and 15.5 million pounds of zinc,
3.5 and 10.1 million pounds of lead and 476,883 and 1,762,245 ounces
of silver in concentrates, respectively. Lead and zinc production are
higher than would be typical for the mineral reserve as a result of
the Cozamin mine focusing on lower copper, higher lead-zinc areas of
the mine while new, deeper, high grade copper areas were being
developed and while lead and zinc prices remain high. In addition,
access to some of the low copper, higher lead-zinc areas would have
been permanently lost in the normal mining process if not extracted
now, and so were mined while lead and zinc prices make these areas
profitable. Final by-product gold production is not available since
assaying is done off site, but is estimated at 8,790 and
28,579 ounces, respectively.
- Production of 23.9 million pounds of payable copper in the fourth
quarter and 86.6 million pounds of payable copper for the full year
of 2009 after adjustments.
- Total cash cost per pound of payable copper produced(1) of US$1.04
in Q4/09 and US$1.03 for the year versus previously published
guidance of approximately US$1.00 per pound for the year. This
performance reflects good cost containment during the low production
cycles at both mines and the return to higher production levels in
Q4/09. Higher by-product credits at Cozamin and higher throughput at
Minto helped offset the lower copper feed grades.
- Cozamin Mine results for the three and twelve months ended
December 31, 2009, respectively, were:
- Produced 8.9 million and 36.1 million pounds of copper contained
in concentrates, respectively, along with by-products of
4.7 million and 15.5 million pounds of zinc, 3.5 million and
10.1 million pounds of lead and 387,665 and 1,462,478 ounces of
silver;
- Produced 8.6 million and 34.6 million pounds of payable copper at
an estimated total cash cost(1), net of estimated by-product
credits and estimated selling costs, of US$0.94 and $0.90 per
pound of payable copper produced; and
- Tonnes of ore processed during Q4/09 remained below design and
below actual processing capacity as a result of the larger, higher
grade stopes being ramped up to full capacity more slowly than was
previously anticipated as a result of management's decision to add
more ground support in the larger stopes to ensure there are no
future hanging wall stability issues. This shortfall of ore
processed was partially mitigated by bringing back on line some of
the stopes in the upper portions of the mine with higher lead and
zinc grades, taking advantage of the current high prices for these
metals.
- Minto Mine results for the three and twelve months ended December 31,
2009, respectively, were:
- Produced 15.8 million and 53.7 million pounds of copper contained
in concentrates, along with by-product 89,218 and 299,767 ounces
of silver and gold estimated at 8,790 and 28,579 ounces;
- Produced 15.3 million and 51.9 million pounds of payable copper at
an estimated total cash cost(1), net of estimated by-product
credits and estimated selling costs, was US$1.10 and $1.12 per
pound of payable copper produced;
- Plant throughput in Q4/09 was similar to that in Q3/09 and
primarily reflects commissioning and optimization of the modified
crushing circuit, which has had a dedicated hydra-cone crusher
installed in anticipation of the Phase IV expansion of the mine;
and
- Completion of the Phase IV pre-feasibility study, demonstrating a
longer life for the Minto Mine and opportunities for further
expansions.
- Kutcho Project:
- Based on the results of a preliminary economic assessment for a
smaller tonnage, higher grade, underground mining operation, the
focus in the latter part of 2009 has been on the two most
significant opportunities for enhanced project economics -
improved metallurgical performance and access to lower cost power.
Metallurgical test programs are underway at both SGS Lakefield and
at Capstone's Cozamin mine metallurgical facilities.

Unit operating costs at the Cozamin mine during Q4/09 were higher than earlier in 2009 as a result of additional development following the design and implementation of a more conservative approach to the ground support and back filling of the very wide, high grade areas of the Cozamin deposit in order to ensure long term stability of this critical mining area. In addition, there were additional costs in the quarter for one time equipment rentals and power generation related to the completion of the 115kV power line, and capital equipment purchases that will be done early in 2010, and an accounting provision for employee benefits and profit sharing related to all of calendar 2009.
As previously disclosed, development of very wide (20-30m) high grade areas of the Cozamin deposit were delayed because the wide mineralization extended deeper and wider than anticipated and this mineralization needs to be extracted from the bottom up in order to ensure geotechnical stability. As a result, development needed to be pushed deeper in order to get to the bottom of the high grade before commencing ore extraction and, in the interim, production came from shallower areas with lower copper but higher lead and zinc content. This affected Q3/09 and, to a lesser extent, Q4/09 production and operating costs.
Development of the wider ore zones was completed at the end of Q3/09 and production drilling and ore extraction has been underway throughout Q4/09. Production from these high grade areas has ramped more slowly than was originally projected as a result of a cautious approach to implementing and extracting ore from these critical areas to ensure long term geotechnical stability. A cable bolting and waste backfill ground support system was implemented to support the hanging wall in the wide ore zone and ensure geotechnical stability and reduce risk of dilution. The resulting lower copper production was been somewhat offset by significantly higher than planned lead production as shallower, high lead-zinc stopes were brought back into production following the rapid rise in lead and zinc prices over the past several months.
Given continued high lead and zinc prices, Cozamin will continue to take a flexible approach to production from higher grade lead and zinc areas in order to crystallize profitability from these areas while maintaining overall operational cash flow.
During the three months ended December 31, 2009, the Cozamin Mine shipped and recorded as revenue 14,672 dmt of copper, 1,906 dmt of lead and 5,322 dmt of zinc concentrates. During the full year of 2009, a total of 68,206 dmt of copper concentrates, 6,762 dmt of lead concentrates and 18,569 dmt of zinc concentrates were shipped and recorded as revenue.

The Minto Mine made excellent progress in recovering from the production shortfalls encountered in Q3/09 related to excess water diverted into the open pit and subsequently treated and discharged. While mill throughput remained strong at levels seen in the prior two quarters, the installation and commissioning of a new hydra-cone crusher to provide secondary crushing ahead of the SAG mill, in line with the Phase IV expansion study recommendation limited overall net mill throughput for the period and this set up is still being optimized in Q1/10.
Unit operating costs for the Minto Mine in Q4/09 were higher than in prior quarters due to impact of Capstone's decision to accelerate mining with extended shift schedules in order to ensure maximum ore extraction from the pit prior to freshet in 2010 so that any resulting impact on production can be avoided or minimized. As a result of this decision, accelerated extraction of ore and waste from the Phase 4 push back in the pit, with the higher strip ratio related to the Phase 4 push back, increased operating costs, even after adjustments for stockpiling and inventory adjustments. In addition, on an annual basis, the strengthening of the Canadian dollar relative to the US$ (up 15.9%) affects Minto's operating costs, which are reported in US$ but mostly incurred in Canadian dollars.
During the three months ended December 31, 2009, the Minto Mine shipped and recorded as revenue 10,517 dmt of copper concentrate. For the twelve months a total of 59,459 dmt were shipped and recorded as revenue. Only one shipment was made in the fourth quarter as truck access to the mine was not available due to the Yukon River freeze-up. Concentrate trucking commenced again on January 11, 2010 with the opening of the ice bridge across the Yukon River.
Minto PFS
As announced December 15, 2009, Capstone reported the results of an independent preliminary feasibility study on the Phase IV expansion of the Minto Mine that detailed an extended mine life from the Minto Mine from open pit sources (the "Phase IV PFS"). This study also identified opportunities for the potential development of underground, higher grade production to supplement open pit production. This opportunity has become the focus for consideration of a potential Phase V expansion of the Minto Mine during 2010. Phase V would most likely comprise underground production in parallel with open pit production at the same mill throughput rates as proposed in the Phase IV PFS, resulting in an overall higher feed grade and the open pit production being spread over a longer time period.
Outlook
The production guidance for 2010 was provided in a news release dated December 17, 2009.
