Questcorp Mining Continues Exploration in Advance of Drilling at the La Union Gold & Silver Project in Mexico

Questcorp Mining Inc. (CSE: QQQ) (OTCQB: QQCMF) (FSE: D910) (the ‘Company’ or ‘Questcorp’) is pleased to update shareholders on the on-going surface exploration in preparation for drilling at the La Union Gold-Silver Project in Sonora, Mexico. Questcorp has an Option earn a 100% interest from Riverside Resources Inc. in the 2,520 ha (25 km sq) property by making a series of cash payments and share issuance and completing a series of exploration expenditures.

Questcorp President & CEO, Saf Dhillon, stated: ‘We are pleased with the progress Riverside has made as we complete the preliminary exploration steps, in finalizing our drill targets for the upcoming maiden drill program at La Union. The decades of in country exploration experience that John-Mark and his Riverside team diligently bring to focus at the La Union project is very evident as they continue to further de-risk the up-coming 1,500 metre drill program.’

La Union operator Riverside Resources has successfully completed two IP lines over the La Union and La Union Norte mines respectively, highlighting chargeability and resistivity features at depth which will guide the placement of the first ever drill holes on the property, as well as correlating with mapped mineralized zones and former workings.

A drone magnetic survey was flown over the property to provide structural context, follow up potential intrusive feeders and provide information about potential faults beneath the pediments and post-mineral young cover units.

Ongoing surface geochemistry and mapping continues to strengthen the targeting pipeline, particularly across exposed gold-rich manto zones and along the margins of shallow post-mineral gravel pediment cover. These efforts are focused on delineating the transition zones from covered to exposed mineralization and establishing structural controls that may influence ore continuity at depth.

The La Union Project

The La Union Project is a carbonate replacement deposit (‘CRD’) project hosted by Neoproterozoic sedimentary rocks (limestones, dolomites, and siliciclastic sediments) overlying crystalline Paleoproterozoic rocks of the Caborca Terrane. The structural setting features high-angle normal faults and low-to-medium-angle thrust faults that sometimes served as mineralization conduits. Mineralization occurs as polymetallic veins, replacement zones (mantos, chimneys), and shear zones with high-grade metal content, as shown in highlight grades of 59.4 grams per metric tonne (g/t) gold, 833 g/t silver, 11% zinc, 5.5% lead, 2.2% copper, along with significant hematite and manganese oxides, consistent with a CRD model (see the technical report entitled ‘NI 43-101 Technical Report on the Union Project, State of Sonora, Mexico’ dated effective May 6, 2025 available under Questcorp’s SEDAR+ profile). These targets also demonstrate intriguing potential for large gold discoveries potentially above an even larger porphyry Cu district potential as the Company’s target concept at this time.

Questcorp cautions investors grab samples are selective by nature and not necessarily indicative of similar mineralization on the property.

Riverside, the operator of the La Union Project, is currently lining up the various geophysical contractors to immediately undertake orientation surveys and follow up detailed survey to confirm and enhance the drill targets.
