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

Vancouver, British Columbia--(Newsfile Corp. - July 24, 2025) - Questcorp Mining Inc. (CSE: QQQ) (OTCQB: QQCMF) (FSE: D910) (the "Company" or "Questcorp") is pleased to further 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 to earn a 100% interest from Riverside Resources Inc. ("Riverside") in the 2,520 ha (25 km sq) property by making a series of cash payments and share issuance and incurring exploration expenditures.

Questcorp President & CEO, Saf Dhillon stated "The Riverside technical team continues to de-risk the upcoming 1500 metre mid-August maiden drill program through detailed surface mapping and sampling. The discovery of multiple stacked thrust faults in the main mineralized area has significantly enhanced the potential of the project. Management continues to be impressed with the excellent work and progress being made with prudent management of exploration dollars".

Riverside continues with surface exploration in advance of the mid-August diamond drill program. The key finding of the work to date has been the identification of stacked thrust faults in the mineralized area which may significantly enhance host rock volume and mineralization potential. Mapping has also identified previously unmapped intrusive bodies within the property which may act as additional sources of mineralized fluids and subsequently addition potential manto type mineralization.

Rock and soil sampling continues with numerous samples dispatched to the laboratory for analysis. Results are expected in the coming weeks. Drilling contractors have toured the site with the contract soon to be finalized. A bulldozer has commenced road maintenance in preparation for the drill program.

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