Columbus Gold Announces Positive PEA Results on Montagne d'Or Gold Deposit; Production of 273,000 Oz/yr and AISC of US$711/Oz
VANCOUVER, BRITISH COLUMBIA--(Marketwired - July 8, 2015) - Columbus Gold Corporation (TSX VENTURE:CGT)(OTCQX:CBGDF) ("Columbus Gold") is pleased to announce the results of the NI 43-101 compliant, Preliminary Economic Assessment ("PEA") at the Montagne d'Or gold deposit, Paul Isnard Project, French Guiana, conducted by SRK Consulting (U.S.), Inc.
Montagne d'Or PEA Highlights
- After-tax NPV (at 8%) of US$324 Million
- After-tax IRR of 23%, at a gold price of US$1200 per ounce ("Oz")
- Initial Capital Cost of US$366M, including US$44M contingency
- All-in Sustaining Costs ("AISC") of US$711/Oz
- Life of Mine ("LOM") Production of 3.05 million ounces
- Average Annual Gold Production 273,000 Oz in years 1-10
- Milling Capacity of 12,500 tonnes per day, with an average gold grade 2.0 g/t in years 1-10
Robert Giustra, Chairman & CEO of Columbus Gold, commented: "The advancement of the Montagne d'Or Gold Deposit to the PEA stage achieves a significant milestone that clearly indicates the potential to develop a low CAPEX gold deposit with scale and good grade, at below industry average cash costs." Mr. Robert Giustra further stated: "The Montagne d'Or PEA is planned to deliver a solid average grade of 2 g/t over a 10 year production period, and with additional drilling and continued refinement of operating costs, including various energy proposals in the upcoming feasibility study, a potential reduction in overall costs may be possible."
Analysis
The Montagne d'Or deposit could potentially support an open pit mine with conventional carbon-in-leach (CIL) processing technology, and with a moderate strip ratio of 5:1 waste/ore. While the PEA allows for inclusion of Inferred Mineral Resources, more than 94% of in-pit resources are in the Indicated Mineral Resource category. The processing plant, with an annual capacity of 4.5 Mtpa, will include three stage crushing, ball milling, gravity gold recovery circuit, 9 CIL tanks, and cyanide detoxification circuit. Gold recovery in the plant is anticipated to exceed 94%, and processing of lower-grade stockpiles is scheduled for years 12 to 13.
The PEA utilizes power supply from on-site generation at a cost of US$0.20/kWh as the base case, however a connection to the power grid located 125 km away at the port of Saint-Laurent-du-Maroni would reduce the cost to US$0.11/kWh. This option is currently at an advanced stage of study. Due to a low Ball Mill Work Index of only 12 kWh/t, the mine is anticipated as having competitive processing cost in either power supply scenario..
