GoldQuest Releases Highlights Of Revised PEA For Romero Gold-Copper Project
VANCOUVER, BC–(Marketwired – April 29, 2015) – GoldQuest Mining Corp. (TSX VENTURE: GQC) (FRANKFURT: M1W) (BERLIN: M1W) (“GoldQuest” or the “Company”) has revised the Preliminary Economic Assessment (“Revised PEA”) for a proposed underground mine at its 100% owned Romero and Romero South gold-copper deposits in the Dominican Republic. The Revised PEA was led by JDS Energy & Mining Inc. (“JDS”). All costs are in US dollars unless otherwise stated, with a USD/CDN exchange rate of 0.80 and metal price assumptions are $1,225/oz gold, $2.90/lb copper and $17/oz silver.
Revised PEA Highlights:
- Pre-tax net present value (“NPV”) of $355 million based on a 6% discount rate ($219 million NPV after-tax).
- Pre-tax internal rate of return (“IRR”) of 46% (34% IRR after tax).
- Life-of-mine (“LOM”) all-in sustaining costs (“AISC”) of $572/oz gold equivalent (“AuEq”) payable.
- Payback of capital within 2.7 production years.
- Pre-production capital expenditure estimate of $143 million, plus $92 million of sustaining and closure capital over LOM totaling $235 million.
- A nine-year underground mine at an average production rate of 912,500 tonnes per year (2,500 tonnes per day) with an average production of 117,000 recovered AuEq oz per year.
- LOM production to concentrate is a total of 1.1 million ounces of AuEq consisting of 750,000 ounces of gold, 133.8 million lbs. of copper and 526,000 ounces of silver.
- Total metal recoveries consisting of 75% for gold and 96.8% for copper to a single concentrate for sale to copper smelters. The concentrate grade is expected to contain 20% copper, and 76.9 g/t gold, with no perceived penalty elements.
- Total LOM net smelter return (NSR) revenue of $1.2 billion, an undiscounted pre-tax cash flow of $530 million ($343 million post-tax) from processing 7.7 million tonnes with a diluted grade of 5.39 g/t AuEq (4.02 g/t and 0.81% copper) with a NSR of $152 per tonne and cash operating costs of $53 per tonne.
- Of the mineral resources used in the Revised PEA mine plan, 86% (6.6 million tonnes) are from the indicated resource category and 14% (1.1 million tonnes) are from the inferred resource category. The remaining 12.8 million tonnes in the indicated category, and 8.9 million tonnes in the inferred category, either surround the planned Romero mine, or are in Romero South and are available for extraction in the future.
- The Revised 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. Previous studies recognized significant values for the hydro electric potential for the mine locale, which are not included in the Revised PEA and which provide significant upside potential.
 Au oz equivalent recovered is calculated by the following: Au oz recovered + ((Cu lbs recovered * $2.90/lb)+(Ag oz recovered * $17/oz))/$1,225oz)
“JDS has designed a high grade underground mine plan averaging 5.39 g/t AuEq, resulting in after-tax NPV of $219 million using a 6% discount rate. We are fortunate that the geometry and metallurgy of the Romero deposit lend the project to being scalable and that we can pursue this higher grade option with simplified processing for Romero, our cornerstone asset in the Dominican Republic,” concluded Chief Executive Officer, Julio Espaillat. “This revised PEA, with a gross margin of $653/oz AuEq, places Romero firmly in the lowest cost quartile of the industry and demonstrates that the economics of Romero are extremely compelling.”
“Goldquest plans to translate the Revised PEA into Spanish and submit it to the Dominican Republic authorities as the basis for the mining permit application,” commented Mr. Espaillat.
Ongoing environmental baseline studies, commenced in December 2012, will be used as part of the mining permit application.

The Revised PEA is preliminary in nature, 14% 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 Revised PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
The following figure presents the Revised PEA sensitivities, showing leverage to metals prices and head grades being the most important variables:
The basis for the Revised PEA is the mineral resource estimate prepared by Micon as set out in the Company’s National Instrument 43-101 (“NI 43-101”) technical 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|
|Total Indicated Mineral Resources||19,420,000||2.63||0.63||0.29||3.7||3.81||1,645,000||2,381,000|
|Total Inferred Mineral Resources||10,020,000||1.64||0.36||0.42||3.8||2.45||529,000||790,000|
|Note: Mineral resources that are not mineral reserves do not have demonstrated economic viability|
The mine plan for the Romero deposit contemplates a ramp accessible underground mine employing cut and fill and mechanized longhole stoping. At full production, crushed material will be transported to the surface at an average rate of 2,500 tpd. 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.
The Revised PEA does not propose exploiting the Romero South deposit.
Processing and Metallurgy:
The processing flow sheet selected for the Revised PEA consists of crushing, grinding, gravity and flotation to produce one concentrate; a copper/gold sulphide concentrate, which is not expected to contain any significant deleterious elements. Approximately 53% of tailings will be used as paste backfill with the balance disposed of in a tailings impoundment area through dry stacking. Total recoveries into the final concentrates, based on existing metallurgical test work, are expected to be approximately 75% for gold and 96.8%.
The operating costs used in the Revised PEA were estimated from first principles using local unit rates for labour, consumables and power where possible. The LOM AISC are estimated to be $572/oz of AuEq per year as set forth in the table below.
|AISC Cash Cost||$/AuEq oz (Payable)*|
|On-Site Operating Cash Costs||396|
|Transportation & Refining||72|
|Total Cash Costs||483|
|Sustaining & Closure Capital||90|
(*) Au oz equivalent payable is calculated by the following: Au oz payable + ((Cu lbs payable * $2.90/lb)+(Ag oz payable * $17/oz))/$1,225oz)
The pre-production capital cost is estimated to be $143 million, plus $92 million for LOM sustaining and closure capital, for a total estimated LOM capital cost of $235 million. Initial capital expenditures are based on an average of 2,500 tonnes per day throughput, and a two year construction period.
Sustaining capital consists of capitalized 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 pre-production capital costs are summarized in the table below.
|CATEGORY||Pre-Production CAPEX Total|
|Material Crushing And Handling||7.1|
|Tailings Management Facility||2.6|
|Pre-Production CAPEX Total||143.1|
*The contingency has been calculated at a rate of 20% and applies to all costs except mining.
A technical report supporting the Revised PEA will be filed on SEDAR within 45 days.
