Questcorp Mining Inc. (CSE: QQQ,OTC:QQCMF) (OTCQB: QQCMF) (FSE: D910) (the ‘Company’ or ‘Questcorp’) is pleased to announce they have completed 25% of the planned drilling program on its La Union Project in northwest Sonora, Mexico. This work is being carried out by property vendor and operator Riverside Resources Inc. (TSXV: RRI).
Highlights
- The Company has completed 300 metres of the planned drill program of 1200 to 1500m.
- Drilling to test the carbonate-hosted replacement deposit (CRD) style of mineralization, with gold associated with mantos, chimneys, and along structural zones.
- Angled drill holes are aimed at cutting perpendicular to stratigraphic targets and some structural targets which is typical in CRD systems
- Structural features may have served as mineralizing conduits and are key targets in the current drill program.
Questcorp is capitalizing on the recent exploration work over the past three months by Riverside that improved the understanding of the structural geology and stratigraphy that is guiding current exploration efforts at La Union. The exploration target focus is for a large potential gold discovery that expands from previous smaller scale mine operations on the property. The drill program will begin to test the new concepts and expand past previous mining.
Saf Dhillon, President & CEO states, ‘Questcorp is pleased with the progress being made at this first ever drill program at La Union. The Riverside team has been able to work throughout these hot summers months to enable the successful completion of this Maiden drill.
Earlier this year, Questcorp entered into a definitive option agreement with Riverside’s wholly owned subsidiary, RRM Exploracion, S.A.P.I. DE C.V. to acquire a 100% interest in the La Union Project. As part of the agreement, Questcorp issued shares to Riverside, making Riverside a shareholder and aligning both parties’ interests in the Project’s success. With funding provided by Questcorp, an initial C$1,000,000 exploration program is now underway. This marks the first phase of a larger, C$5,500,000 work commitment, contingent on exploration results and Questcorp’s continued participation.
The Drill Program Targets include more than four different areas, beginning with this early-stage stratigraphic and orientation phase of drilling exploration aimed at evaluating the scale of alteration and indications of a mineralized system. This will be the first drilling ever conducted on most of the targets, despite past mining having occurred in the majority of these areas. The initial program will consist of one to three holes per area, primarily for orientation purposes. Follow-up drilling is planned and can be expanded based on initial results, which will help verify the stratigraphy, lithologies, and structural features allowing for improved modeling and next-stage discovery targeting. The four areas are listed below:
- Union Main Mine Area – The program will use angled drill holes to test limestone and other carbonate stratigraphic hosts within the Clemente Formation, with the potential to reach the underlying Caborca Formation. These units are considered the primary hosts for replacement-style mineralization.
- North Union Mine Area – The initial focus of the program will be on testing structural interpretations. Additional drilling is anticipated following this first phase, as results will help guide future drill testing of areas with past mining activity and various structural orientations.
- Cobre Mine Area – The Clemente Formation is the primary host unit, and structural features combined with areas of past mining provide multiple target zones. Drilling will begin with an initial stratigraphic test hole to help orient around the thickness of the host unit and extend into the lower Caborca Formation, which is also a favorable host for CRD-style mineralization.
- Central Union Area – Structural targets, as possible mineralization feeder zones, are a key focus in this past mining manto area. There are extensive additional target zones in the area, and this initial orientation drilling will provide vectoring for the next stage of drilling and further study of the Clemente Formation, and possibly into the Caborca Formation as currently interpreted.
General Overview of La Union Project
The Project is summarized in a recently published NI 43-101 Technical Report available under Questcorp’s SEDAR+ profile (www.sedarplus.ca). Riverside initially acquired the Project and subsequently consolidated additional inlier mineral claims, building a strong land position. Riverside then advanced the Project through surface access agreements and drill permitting, making it a turn-key exploration opportunity for Questcorp.
The Project was originally identified through Riverside’s exploration work in the western Sonora Gold Belt, conducted in collaboration with AngloGold Ashanti Limited, Centerra Gold Inc., and Hochschild Mining Plc. Earlier research by Riverside Founder John-Mark Staude also contributed to recognizing the district’s potential. Initial work by members of the Riverside team, drawing on more than two decades of geological compilation and analysis, further confirmed the region as highly prospective.
At the Project, historical mining by the Penoles Mining Company targeted chimney and manto-style replacement bodies within the upper oxide zones. As a result, the underlying sulfide zones represent immediate and compelling drill targets for further exploration.
At the La Union Project, immediate drill targets offer the potential for significant-scale discoveries. La Union is well positioned for near-term exploration success, with targets that include both oxide and deeper sulfide mineralization.
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.
