Centerra Completes Öksüt PEA, Kumtor Ownership Talks Continue
Highlights of the PEA, using a $1,300/oz gold price, include:
• An 11-year mine life from 2016 to 2027;
• Life-of-mine gold production of 893,000 oz, with average production of 125,000 oz/y in years 4 through 6;
• Total construction capital and pre-production costs of $166 million;
• All-in production costs, including taxes, of $914/oz; and
• Payback of construction capital and preproduction costs expected 4.5 years after production begins.
The Öksüt project is based on the Keltepe and Güneytepe gold deposits. The resource estimate used as the basis for the PEA consists of indicated mineral resources from the Keltepe deposit of 29 million mt grading 1.2 g/mt gold for 1.1 million contained oz of gold and inferred mineral resources from the Güneytepe deposit of 4.7 million mt grading 0.9 g/mt gold for 134,000 contained oz.
The PEA assumes mining of two open pits by a local mining contractor. Over the life of the mine, mining costs are estimated to average $2.77/mt mined, processing costs are estimated to average $4.00/mt processed, and administrative costs are estimated at about $9 million/operating year. To account for mining dilution and losses during mining, the mineral resources have had a 95% factor applied to the gold grades and are constrained by an optimized pit shell, a gold price of $1,300 /oz, and an overall metallurgical recovery of 77%.
Potential Kumtor Ownership Restructuring: In other news, Centerra reported on February 6, that the parliament of the Kyrgyz Republic had adopted a resolution after completing a review of a previously announced non-binding heads of agreement among Centerra, the government of the Kyrgyz Republic, and Kyrgyzaltyn JSC in connection with a potential restructuring transaction. In the transaction, Kyrgyzaltyn JSC would exchange its 32.7% equity interest in Centerra for a 50% interest in a joint-venture company that would own the Kumtor gold mine.
Kyrgyzaltyn JSC is a joint-stock company wholly owned by the Kyrgyz Republic. The Kumtor mine is located in the Tien Shan Mountains 350 km southeast of the Kyrgyz capital of Bishkek and accounts for about 12% of the country’s GDP. Centerra is forecasting that the mine will produce 550,000 to 600,000 oz of gold in 2014 at all-in costs of $833 to $909/oz.
Potential restructuring of Kumtor ownership has been the subject of discussion and some disagreement within the Kyrgyz government since September 2013.
“Any definitive agreement for a potential restructuring remains subject to required approvals in the Kyrgyz Republic, including Government and Parliament of the Kyrgyz Republic, as well as Centerra Special Committee and Board approval, and compliance with all applicable legal and regulatory requirements and approvals, including a formal independent valuation and shareholder approval.”
