GoldQuest Mining Corp. Reports High-Grade Assay Results from Metallurgical Drilling At Romero Gold-Copper Project GoldQuest Mining Corp. has reported assay results from five metallurgical drill holes completed at the Company's 100%-owned Romero Gold-Copper Project in San Juan Province, Dominican Republic. The metallurgical holes, LTP-171 through LTP-175, were drilled to provide fresh representative core for the ongoing geo-metallurgical program and bankable feasibility study work. The assay results confirm multiple high-grade gold-copper intervals within the Romero deposit, while metallurgical test work completed to date continues to support conventional processing assumptions and ongoing process design work. The geo-metallurgical program is a key component of the ongoing bankable feasibility study and has focused on representative samples from defined domains within the Romero deposit. The work completed to date indicates that the tested geo-metallurgical domains are all amenable to conventional comminution and flotation processing methods, supporting the process route contemplated for Romero. Comminution testing has identified variation in SAG work indices, particularly for softer ores, providing additional information to better align operating cost assumptions with geology. Flotation test work has identified opportunities to evaluate coarser grinding requirements without loss of recovery, while remaining consistent with recovery assumptions applied in the 2016 PFS. Preliminary test work also suggests that target recoveries may be achievable without the inclusion of a gravity circuit, which could simplify the final flowsheet if confirmed by the remaining work. Mineralogical investigations have been completed to support metallurgical interpretation and address previously identified data gaps, and tailings samples have been generated for ongoing rheological and paste backfill test work. The results reported remain preliminary and subject to completion of the test program, engineering analysis and integration into the bankable feasibility study. Final metallurgical conclusions and design criteria will be reported as the program advances. The metallurgical drill holes were completed as part of the Company's broader geo-metallurgical program for Romero. The program is designed to provide fresh material for comminution, flotation, variability and life-of-mine composite test work, as well as additional geological information to support the feasibility study. GoldQuest is evaluating the integration of the new metallurgical drilling into the ongoing mineral resource estimate update and related feasibility study workstreams. Core from these holes was partially assayed as part of the metallurgical test program at ALS Metallurgy at Kamloops, Canada, and the remainder of the core was assayed at Bureau Veritas. As part of the Company's Quality Assurance and Quality Control procedures, the Company reviews results from Certified Standard Reference Materials, 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 Bureau Veritas 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 0.0025 g/t value. All drill samples were prepared and screened by ACME Labs (Vancouver); metallic fire assay and multi-element ICP-MS were assayed by Bureau Veritas 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. The scientific and technical information contained in this press release has been reviewed and approved by Leandro Sastre, P. Geo., VP of Exploration of GoldQuest, and Franco Martucci, P.E., Senior Metallurgical Engineer. Mr. Sastre is responsible for the exploration and geological information, and Mr. Martucci is responsible for the metallurgical information. Each is a Qualified Person for their respective technical information under NI 43-101 - Standards of Disclosure for Mineral Properties. Recent Insider Transactions • May 20

GoldQuest Mining Corp. Reports New High-Grade Polymetallic Massive Sulphide Discovery At Cachimbo Target GoldQuest Mining Corp. announced results from the ongoing exploration campaign at the Cachimbo target. Drill hole TIR-26-58 has intersected a significant high-grade polymetallic zone, confirming a new mineralized parallel structure located to the northeast of the known Cachimbo mineralized zone. The intercept returned high-grade values for gold, silver, copper and zinc, with a notable high-grade core of 3.59 metres grading 17.63 g/t AuEq. This discovery represents the first major drill success at Cachimbo following the resumption of drilling after a nine-year hiatus and identifies a new target for additional drill testing. TIR-26-58: 12.26 m @ 2.52 g/t Au, 50.7 g/t Ag, 0.94% Cu & 12.0% Zn from 104.5 m depth. High-Grade Core: Including 3.59 m @ 5.74 g/t Au, 128.88 g/t Ag, 2.18% Cu, and 27.6% Zn. New Structure: The intercept confirms a new mineralized parallel structure, significantly expanding the potential footprint of the Cachimbo discovery. Open at Depth: Mineralization remains open in multiple directions, with further drilling planned to test the continuity of this new zone. Geophysics Program Underway: A Pole-Dipole Induced Polarization (PD-IP) survey is being executed to improve drill targeting. Hole TIR-26-58 was positioned to test a structural offset identified through recent detailed structural re-interpretation. The mineralization is hosted within a sequence of lithic and mafic tuffs, characterized by massive to semi-massive sulfide assemblages. The presence of high-grade copper (2.18% Cu) silver (128.88 g/t Ag) and zinc (27.61% Zn) within the core of this intercept confirms that the new parallel structure is a high-tenor polymetallic system. This second structure significantly expands the potential volume of the Cachimbo target, as it remains open along strike and down-dip. Table 1 below shows a detail of the intercepts and grades. Table 1: Results from hole TIR-26-58 HoleID From(m) To(m) Interval(m) Au g/t Cu % Ag g/t Pb % Zn % Au Eq g/t TIR-26-58 64.65 76.91 12.26 2.52 0.94 50.7 0.26 12.0 7.62 Includes 73.32 76.91 3.59 5.74 2.18 128.88 0.65 27.61 17.63 *Interval grades are calculated using uncapped assays. Gold values did not exceed 21.9 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. AuEq was calculated by using metal prices of Au USD 3,450/ounce, Cu USD 5.1/pound, Ag USD 37.4/ounce, Zn USD 3,280/ton and Pb USD 1,920/ton. No metal recoveries utilized. Exploration at Cachimbo is ongoing. While the initial results for TIR-26-58 are encouraging, assays for the second half of the hole remain pending and are expected shortly. Furthermore, drilling of holes TIR-26-57 and TIR-26-59, which targeted the down-dip extension of the primary Cachimbo zone, have been completed. Results from hole TIR-26-57 did not return significant intercepts, while results for hole TIR-26-59 are currently pending laboratory analysis. The rig has now transitioned to TIR-26-60, targeting deep extension of Cachimbo. In addition to the drilling, a new PD-IP survey is now being carried out. Two lines are already completed, and results shows a good correlation between low and high chargeability contrast and mineralization, especially at the newfound VMS structure. Annonce • Feb 27
