GoldQuest Mining Intersects 11.7 Metres Grading 6.3 g/t Gold at Cachimbo Discovery, Dominican Republic

VANCOUVER, BC--(Marketwired - August 10, 2017) - GoldQuest Mining Corp. (TSX VENTURE: GQC) (FRANKFURT: M1W) (BERLIN: M1W) ("GoldQuest" or the "Company") is pleased to report assay results from the latest 4-hole batch of drill holes from its ongoing Tireo exploration drill program. The holes are all from the recent Cachimbo Volcanogenic Massive Sulphide (VMS) Discovery. All drilling occurs within the Company's 100% owned Tireo Concessions, which hosts the multi-million-ounce Romero Project in the Dominican Republic.

Highlights:

TIR-17-35 intersected two gold mineralization zones including:

• 46.6 metres of 1.08 g/t gold
• And 11.7 metres grading 6.34 gold
• Including 1.3 metres grading 47.7 g/t gold, 30 g/t silver, 2.32% zinc and 0.18% copper

Assays from four holes at Cachimbo are reported herein. All four holes, TIR-17-33, 34, 35 and 36 intersected gold within the upper strata-bound polymetallic massive and semi-massive sulphide horizon of the VMS system. Hole TIR-17-35 intersected a second lower zone of mineralization which may be proximal to the feeder to the system and future drilling will follow up. The mineralization remains open along strike and down-dip of the Cachimbo discovery hole, TIR-16-09, which intersected 5 metres grading 14 g/t gold, 74 g/t silver, 12% zinc and 1% copper (see release dated January 10, 2017).

Hole TIR-17-33 was collared approximately 50m south-east of the discovery hole at the same platform as hole TIR-17-32. The hole confirms that the upper mineralization horizon is dipping to the east. Holes TIR-17-34/35 and 36 were collared approximately 160 metres to the south-east of the discovery hole. Hole TIR-17-34 suffered a mechanical failure just as it entered the mineralization zone and had to be abandoned. Hole-17-35 hit the intended target of hole TIR-17-34 and intersected a second deeper zone with higher gold and base metal grades.

Drilling continues at Cachimbo and will test areas along strike to expand the mineralization envelope as the Company continues to explore for a potential copper-gold rich feeder system, like the Romero Deposit.

"About a year ago we launched our regional Tireo drilling campaign seeking new significant gold deposits. Today we are proud to share results from the latest holes from the definition phase of our Cachimbo discovery," commented Bill Fisher, GoldQuest's Executive Chairman. "It is early days and with each new hole we unveil more of the story of the Cachimbo geology and its potential. We are proud of our successes and in our continued ability to find gold in this emerging mineral district."

*Interval grades are calculated using uncapped assays. Gold values did not exceed 47.7 g/t which is below the capping level for Romero of 72.2 g/t. Intervals may not represent true widths. There is insufficient drilling to determine the exact orientation of the mineralized zones at this time.

QA/QC

As part of the Company's Quality Assurance and Quality Control procedures (QA/QC) the Company reviews results from Certified Standard Reference materials (CRSM or Standards), which are inserted at a rate of five per 100 samples. Within the results disclosed herein there were no samples with results outside of the recommended tolerances for the standards. In GoldQuest's drill programs, composite intervals were chosen using a combination of geological criteria and mineralization, averaging around two metres core length. The drill core is cut in half with one half of the core sample shipped to ACME Labs by GoldQuest technicians. The remaining half of the core is kept at the Company core shack for future assay verification, or any other further investigation. Assays within intervals below the 0.005 g/t detection limit for Au were given a zero value. All drill samples were prepared and screened by ACME Labs (Vancouver); metallic fire assay and multi‐element ICP‐MS were assayed by ACME Analytical Laboratories (Vancouver). Gold values are determined by standard fire assay with an AA finish, or, if over 10.0 g/t Au, were re‐assayed and completed with a gravimetric finish. Copper and zinc values exceeding 0.2% were re-assayed with a 4-acid digestion and AAS finish. When zinc values exceeded 10% a classic titration was carried out for zinc. QA/QC included the insertion and continual monitoring of numerous standards, blanks and duplicates into the sample stream, at random intervals within each batch.
