VANCOUVER, BC--(Marketwired - June 02, 2015) - GoldQuest Mining Corp. (TSX VENTURE: GQC) (FRANKFURT: M1W) (BERLIN: M1W) ("GoldQuest" or the "Company") has filed on SEDAR the National Instrument 43-101 (NI 43-101) technical report for its revised 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. Highlights of the Revised PEA were previously announced on April 29, 2015. The Revised PEA was led by JDS Energy & Mining Inc. ("JDS"). All costs are in US dollars.

"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. We are in the process of translating the Revised PEA into Spanish for submission to the Dominican Ministry of Energy and Mining in order to start the mining permit application process," stated Chief Executive Officer, Julio Espaillat.

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 AuEq oz recovered[1] 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 results in an undiscounted pre-tax cash flow of $530 million ($343 million post-tax) from processing 7.7 million tonnes of material with a diluted grade of 5.39 g/t AuEq (4.02 g/t and 0.81% copper), an 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.

[1] AuEq oz recovered is calculated by the following: Au oz recovered + ((Cu lbs recovered * $2.90/lb)+(Ag oz recovered * $17/oz))/$1,225oz)

The Revised PEA is preliminary in nature, includes 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 Revised PEA will be realized.

At March 31, 2015, the Company had approximately $4.8 million in treasury. The unaudited interim financials for the first quarter ended March 31, 2015 were filed on SEDAR on May 27, 2015.
