90,000 Ounces of Gold per Year for an All-In Sustaining Cost of $353/Ounce
VANCOUVER, BC--(Marketwired - May 27, 2014) - GoldQuest Mining Corp. (
- A 15 year underground mine producing an average of 90,000 ounces of payable gold and 15.6 million lbs. of payable copper for each year of full production in two concentrates from 3,800 tonnes per day (129,000 ounces of gold equivalent ("AuEq"))
- All-in sustaining costs ("AISC"), net of copper and minor silver by-products, of $353/oz for 90,000 ounces of gold per year consisting of on-site operating cash costs (net of by-product credits of $557/oz) of $153, concentrate transportation and Treatment Charges /Refining Charges ("TC/RCs") costs of $147/oz, royalties of $21/oz and sustaining capital of $32/oz
- Metal recoveries are estimated to be 83% for gold and 91% for copper resulting, after allowing for transportation and TC/RCs, in net payable gold of 79.2% and net payable copper of 86.5%
- Total Life of Mine ("LOM") revenue of $2.35 billion, an undiscounted pre-tax cash flow of $0.86 billion ($0.60 billion post tax), producing 1.26 million ounces of payable gold (1.81 million payable ounces of AuEq.) from processing 18.5 million tonnes grading 2.69 g/t and 0.61% copper with a Net Smelter Return of $117 per tonne and cash operating costs of $58.69 per tonne
- Total LOM capital cost of $374 million, which includes an initial capital cost of $333.5 million and a sustaining capital cost of $40.4 million
- Pre-tax Internal Rate of Return ("IRR") of 19.7% (15.1% after tax)
- Pre-tax Net Present Value ("NPV") of $318 million based on an 8% discount rate ($176 million after tax)
- Pre-tax NPV of $471 million based on a 5% discount rate ($274 million after tax)
- PEA completed only 2 years after discovery
- Of the mineral resources used in the PEA mine plan, 80% are from the indicated category
- The PEA contemplates an environmentally sensitive approach, including a small surface footprint and no use of cyanide on site, seeking to minimize the impact on the environment and the local communities
"We are proud to deliver a positive PEA for the Romero Project, our cornerstone asset in the Dominican Republic," commented Chief Executive Officer, Julio Espaillat. "Building on our low net All-In Sustaining Costs, we are actively addressing the capital intensity issues of the Romero project through ongoing optimization studies. We also hope to add value through discovery of new resources, which is the focus of our 10,000 metre 2014 exploration drilling program."
The PEA is preliminary in nature, 20% of the mine plan consists of inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the results of the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

The following figure presents the PEA sensitivities, showing leverage to metals prices being the most important variable:
The basis for the PEA is the mineral resource estimate prepared by Micon as set out in the Company's National Instrument 43-101 ("NI 43-101") report dated December 13, 2013 and effective October 29, 2013 entitled "A Mineral Resource Estimate for the Romero Project, Tireo Property, Province of San Juan, Dominican Republic", which was filed on SEDAR on December 13, 2013. Please refer to the technical report for further information regarding the mineral resource estimate. For the purposes of reporting the mineral resources, Micon selected a net smelter returns ("NSR") cut-off of US$60 (operating cost/commodity price weighted recovery) as an estimate of what might be a reasonable marginal cost of extraction at Romero and US$50 as the marginal cost of extraction at Romero South. Metal prices used were Au = US$1,400/oz., Ag = US$22.50/oz., Cu = US$3.18/lb. and Zn = US$0.95/lb.
A summary of this resource is:
|Category||Zone||Tonnes||Au (g/t)||Cu (%)||Zn (%)||Ag (g/t)||AuEq (g/t)||Au Ounces||AuEq Ounces|
Note: Mineral resources that are not mineral reserves do not have demonstrated economic viability.
The mine plan for the Romero deposit uses mechanized longhole stoping with both ramp and shaft access. At full production, crushed ore is hoisted to the surface at an average rate of 3,800 tpd. The mining method requires sinking and equipping the shaft, installing the primary crusher station at the bottom of the mine and making provision for backfill from bottom up during the pre-production development period, which generally increases up-front capital (lowering IRR) but results in lower sustaining capital and lower operating costs per tonne, compared to other operations. The mine plan includes provisions for mining losses and dilution. Some further drilling is recommended to upgrade inferred resources to the higher measured and indicated categories, as well as geotechnical and metallurgical drilling as part of any pre-feasibility study.
It is proposed that the Romero South deposit would go into production in year 14. The mine plan takes advantage of the deposit outcrop and requires very little waste development. Modified room and pillar mining with backfill is the proposed mining method. The planned production rate is 2,700 tpd and the mining is expected to continue through the third quarter of year 15.
Processing and Metallurgy:
The processing flow sheet selected for the PEA consists of crushing, grinding and flotation to produce two concentrates; a copper/gold sulphide concentrate and a gold oxide concentrate, neither of which contains any significant deleterious elements. 92% of the total copper and 51% of the total gold reports to the copper concentrate and 32% of the total gold reports to the gold concentrate. Bio-oxidation will be used for the gold concentrate only and dry stacking will be used for tailings disposal. This flow sheet is based on extensive metallurgical testing carried out by ALS laboratories in Kamloops BC and Perth Australia under the supervision of Micon. Total recoveries into the final concentrates, based on existing metallurgical test work, are expected to be approximately 83% for gold and 91% for copper resulting in net payable gold of 79.2% and net payable copper of 86.5%. Both concentrates will be trucked from the mine site for further processing.
The operating costs used in the PEA were estimated from first principles using local unit rates for labour, consumables and power where possible, and Micon's estimates for the off site costs. The Life of Mine All-In Sustaining Costs (AISC) are estimated to be $353/oz of Au per year, for 90,000 ounce of Au per year, consisting of on-site operating cash costs of $153/oz, net of copper and minor silver by-products, concentrate transportation and TC/RC costs of $147/oz, royalties of $21/oz and sustaining capital of $32/oz.
The pre-production capital cost is estimated to be $333.5 million, plus $40.4 million for LOM sustaining capital, for a total estimated LOM capital cost of $374 million, for a pre-production capital intensity of $18.07 per LOM tonne processed. Initial capital expenditures are based on 3,800 tonnes per day (1,380,000 tonnes per year) throughput. The up-front capital costs include the underground mine, processing facilities, infrastructure and hydro-electric installations prior to production and include contingencies of $52.4 million, EPCM costs of $19.8 million and $55.4 million for infrastructure costs including the hydro-electric installations. Project electrical requirements are estimated at 14MW.
Sustaining capital consists of capitalized waste development after the initial production start-up, major equipment replacement and tailings expansions. Mining development costs during production are included in the mining operating costs.
The estimated preproduction capital costs are summarized in the table below.
|Capital Costs||Start Up||Start Up||Start Up||Start Up|
|US$ Thousand||Minus 2||Minus 1||Year 1||Total|
*Includes access road, dry stack tailings storage facility, grid power connection and hydro-electric installations.
