Capstone Mining 2017 Production Results and 2018 Operating and Capital Guidance

PR Newswire

VANCOUVER, British Columbia, January 10, 2018

VANCOUVER, British Columbia, January 10, 2018 /PRNewswire/ --

Capstone Mining Corp. ("Capstone") (TSX: CS) today announced production results for the three and twelve months ended December 31, 2017 and provided its operating and capital expenditure guidance for 2018 along with a three-year outlook.

"We ended the year with solid copper production for the fourth quarter," said Darren Pylot, President and CEO of Capstone. "Our operations continue to run well in 2018, positioning us to take advantage of strong copper prices, with our entire copper hedge program now completed."

"We are guiding production for 2018 consistent with our 2017 production. Planned capital expenditures in 2018 of $100 million reflect scheduled haul truck maintenance at Pinto Valley, the continuation of operations at Minto and an increased allocation for exploration at Cozamin, following up on 2017's significant exploration success,"  continued Mr. Pylot.

2017 Production Results 

Combined production totalled 23,400 and 90,300 tonnes of copper in the fourth quarter and full year, respectively, with additional by-products of zinc, molybdenum, lead, silver and gold.

(1) Adjustments based on final settlements will be made in future periods.(2) Pinto Valley gold production reaches payable levelsfrom time to time. Any payable gold production will be reported in the period revenue is received. At Minto, final gold production is not available since assaying is conducted off-site, but is estimated above. (3) Grade and recoveries were estimated based on concentrate production. *Silver and gold have not been estimated in the Pinto Valley resource model. Only recovered silver and payable gold is reported for this mine.

2018 Operating and Capital Guidance 

In 2018, Capstone expects to produce 90,000 tonnes (±5%) of copper at a C1 cash cost (1,2) of $1.85 to $1.95 per pound of payable copper produced. Capital expenditures for 2018, including $24 million of capitalized stripping and $7 million of brownfield exploration, are expected to be $100 million or $0.50 per pound of payable copper produced. Consolidated all-in sustaining cost guidance is $2.50 to $2.60 per pound of payable copper produced. The subsequent two-year outlook is included to illustrate the overall trend of our existing operations, excluding any further growth through project development or acquisition.

(1) This is alternative performance measure;please see "Alternative Performance Measures" at the end of this release. (2) C1 cash cost per pound of payable copper produced net of by product credits and selling costs. (3) All-In sustaining cost per pound of payable copper produced is C1 cash cost plus NSR and production royalties, non cash deferred revenue, all sustaining capital expenditures(including cash portion of production-phase apitalized stripping), accretion of reclamation obligations, amortization of reclamation assets, corporate G&A and cash portion of pre-production capitalized stripping.

Pinto Valley:  In 2018, focus will continue to shift from maximizing throughput to overall plant optimization. Throughput is targeted at, or above, the level contemplated in the PV3 pre-feasibility study. Operating costs are expected to remain relatively flat from 2017; however, unit costs on a per pound basis are expected to be higher as a result of lower grade and a higher strip ratio than 2017 in accordance with the PV3 mine plan. The lowest grade material for the year will be milled in the first quarter, with higher head grade for the remainder of the year.

Cozamin: Milled tonnes are expected to be similar to 2017 with grade down slightly. The majority of ore will continue to come from the Mala Noche Footwall. The 2018 guidance does not include any additional zinc production from the San Rafael Zinc zone. Metallurgical work is continuing with positive results to date and, if confirmed in the first half of the year, we could take advantage of underutilized mill capacity for additional zinc production in the second half of 2018 and beyond.

Minto: Open pit mining in 2018 will comprise the Area 2 extension and the Ridgetop North Pit. Underground mining will take place in the Area 2 Lower Lens, Minto East Underground and Copper Keel. Copper grade is expected to be relatively consistent at plus 1.5% throughout the year with throughput maintained at above 3,900 tonnes per day. Costs however, will fluctuate significantly as stripping and development will be expensed as incurred with the most significant impact expected in the second and third quarters. The current mine plan continues through mid-2021, with production gradually falling starting in 2019, reaching approximately 75% of the 2018 production level by 2021. 

Copper Production and Costs 2019 and 2020: Consolidated production for 2019 and 2020 is expected to average 86,000 tonnes of copper annually at a consolidated C1 cash cost of approximately $1.95 per pound of copper.

2018 Capital Expenditure Guidance - Operating Mines (US$M) 


                            Pinto Valley   Cozamin     Minto     Total
    Sustaining                       $44       $19        $6       $69
    Capitalized Stripping *           24         -         -        24
    Total Capital                    $68       $19        $6       $93

* Capitalized stripping is included as an operating cost in the PV3 PFS, however,under IFRS accounting guidelines stripping costs are capitalized when the strip ratio is higher than the life-of-mine strip ratio.

Pinto Valley: The largest category of sustaining capital in 2018 is $18 million for mining fleet component replacements, which includes scheduled haul truck maintenance driven by operating hours on the existing fleet in accordance with the preventative maintenance plan. Other key sustaining costs include replacing the current rougher flotation cells ($7 million), and SX/EW repurposing initiatives ($4 million), crushing improvements ($3 million), pit dewatering ($2 million) the advancement of PV3 permitting ($2 million) and replacement of underground power lines with overhead lines ($2 million). 

Cozamin: The majority of 2018 sustaining capital expenditures is for mine development, with additional sustaining capital for ventilation and production equipment capitalized maintenance.

Minto: As a result of mine life extension beyond 2017, capital will be required for increased underground ventilation, dewatering and electrical infrastructure. Additional delineation drilling will take place along with minor replacement of equipment that has reached the end of its useful life.

Capital Expenditures 2019 and 2020: In 2019 and 2020, total sustaining capital expenditures at our operating mines are expected to average $55 million annually (excluding capitalized stripping). Capitalized stripping at Pinto Valley for 2019 and 2020 is expected to average $12 million annually.

* Greenfield exploration will be expensed.

Brownfield Exploration: The 2018 brownfield exploration program will include 45,000 metres of step-out and infill drilling aimed at extending the mine life at Cozamin. The majority of drilling will focus on the Mala Noche Footwall Zone to follow up on the significant 2017 drilling success, including testing on newly acquired property contiguous to Cozamin.

Greenfield Exploration: Capstone has exited Project Providencia in Chile, however will allocate funds for additional greenfield exploration opportunities in both Mexico and Chile. Four technical discoveries were made at Providencia, including two deposits, however, data suggests they are not of a size meaningful to Capstone.
