Questcorp Defines Near-Surface Gold Discovery Corridor at Union Norte Expanding District-Scale Potential at La Union

Questcorp Mining Inc. (CSE: QQQ) (OTCQB: QQCMF) (FSE: D910) (the "Company" or "Questcorp") , is pleased to report results from the Phase 2A summer 2026 core drilling campaign, operated by Riverside Resources Inc. ("Riverside") on the Company's behalf, at the La Union Project in northwestern Sonora, Mexico. Drilling intersected near-surface gold and polymetallic mineralization at Union Norte, confirmed the continuation of the historic Sproul manto/replacement system at Union Mine, and further advanced several priority targets ahead of the upcoming Phase 2B drill program. Questcorp enters Phase 2B with a district-scale target inventory that management believes provides multiple independent opportunities for discovery across a single land package.

Phase 2A Highlights UND26-015 - Union Norte: 14.60 m grading 0.45 g/t AuEq from 1.00 m depth, including 5.60 m grading 0.96 g/t AuEq and 4.60 m grading 1.09 g/t AuEq. The hole intersected the interpreted NNW-trending mineralized feeder structure at shallow depth, providing a clear target for follow-up drilling along strike and down dip. UND26-014 - Union Norte: 9.10 m grading 0.76 g/t AuEq from 1.90 m depth, including 4.50 m grading 1.18 g/t AuEq and 1.50 m grading 3.38 g/t AuEq. Together with UND26-015, the result confirms continuity of the near-surface mineralized structure between adjacent drill sections. Union Mine: UND26-013 intersected the interpreted continuation of the historic Sproul manto/replacement body south of historic workings. Anomalous lead and zinc values support the geological interpretation and provide vectors for deeper follow-up drilling toward the interpreted feeder structure beneath the Union Mine. Luis Hill: Induced polarization ("IP") surveying delineated a large chargeability anomaly extending for more than 1 km along strike and to approximately 300 m depth. The anomaly coincides with sediment-hosted gold mineralization identified during Phase 1 and remains open along strike and at depth. The target has not yet been adequately drill-tested.

Phase 2A followed the fall 2025 Phase 1 program and an intensive 2026 exploration campaign that included detailed mapping, underground and surface sampling, structural interpretation and geophysics. The combined work has refined the Company's carbonate replacement deposit ("CRD") model, strengthened the sediment-hosted gold thesis and generated a broader pipeline of drill targets across the Union district. The Phase 2B program is planned to resume after the rainy season, with follow-up drilling focused on Union Mine, Union Norte, Luis Hill and Jabali. For Questcorp shareholders, the practical outcome of Phase 2A is a materially better-defined target set: the Company now has four drill-ready targets across its La Union land position, each supported by a combination of drilling, surface geochemistry and geophysics rather than by a single dataset.

Questcorp President & CEO Saf Dhillon commented: "Phase 2A has materially advanced our understanding of the La Union mineral system and, importantly, provided clear geological vectors for the next stage of drilling. At Union Norte, two adjacent shallow holes have now demonstrated continuity of the interpreted mineralized feeder structure, while at Luis Hill the IP program has defined a large target coincident with previously identified sediment-hosted gold mineralization that remains largely untested.

"Taken together with the historic high-grade mineralization at Union Mine and the growing inventory of targets across the property, we believe Phase 2A has strengthened the technical case for a broader mineralized system at La Union. With the upcoming Phase 2B program, our objective is now to systematically test continuity, scale and higher-grade portions of these systems as we advance the project toward a potentially meaningful discovery.
