Questcorp Mining Announces Commencement of Phase 1 Work at the La Union Gold Project

Questcorp Mining Inc. (CSE: QQQ) (OTCQB: QQCMF) (FSE: D910) (the "Company" or "Questcorp") is pleased to announce the commencement of the first phase work program at its La Union carbonate replacement deposit (CRD) project, located in Sonora, Mexico. Questcorp is earning 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.

The initial stages of phase one will concentrate on finalizing the location of drill targets and drill pads for the upcoming drill program. Field activities are underway and include:

• Establishment of 5 to 6 one kilometre picket lines for IP surveying which commenced on Monday. The IP lines are being run over the heart of some of the past mining areas which continue to be known expansive target areas to help evaluate further potential, possible most favorable zones and assist to model the larger context for the upcoming drill holes. This work further de-risks the up-coming first pass drill holes.
• Sampling of limestone and dolomite host rocks across the mineralization from country rock through to the heart of mineralization for Black Light analysis and alteration vector modeling. The objective is to use the changes or variance in fluorescence to map alteration patterns to vector into the heart of the manto and chimney plumbing systems.
• Geological mapping of drill collar sites and section lines particularly along the surface of the IP lines to help develop the most accurate interpretations of the IP data for drill hole planning.
• Rock and soil sampling of peripheral areas to identify additional targets including study of the stratigraphy for understanding and context with the many mineralization showings on the large district holding.

"We are extremely pleased to initiate the fully funded first phase work program at La Union," commented Questcorp President & CEO Saf Dhillon. "We are first concentrating on de-risking the upcoming 1,500 metre drill program scheduled for mid to late Q3 through alteration mapping and IP geophysics," he continued. "Under the technical expertise of John-Mark Staude and the Riverside team we are confident we are maximizing every exploration dollar being invested at La Union," he concluded.

Riverside Resources Inc. President & CEO John-Mark Staude stated "The work program is going well, I have been in the field this past week with the exploration team and pleased to see the safe, high quality focus of good work and diving into careful review of the planned drill sites and now the IP program is underway. It is great to work with Saf, Tim and the entire Questcorp organization."

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.
