Questcorp Mining and Riverside Resources Commence Phase 2 Exploration Program at the La Union Project, Sonora, Mexico
MWN-AI** Summary
Questcorp Mining Inc. and Riverside Resources Inc. have initiated the Phase 2 exploration program at the La Union Project in Sonora, Mexico, following the encouraging results from their Phase 1 drill program. The Phase 1 program yielded promising findings, including a high-grade 30-meter chip-channel interval at the Union Mine, which graded 20.2 g/t gold and 226 g/t silver, alongside the identification of new sediment-hosted gold at Luis Hill with a 42-meter intersection grading 0.3 g/t gold.
The newly commenced Phase 2 program aims to build on these successes, focusing on refining existing drill targets while also exploring new opportunities across the property. Field teams have mobilized to four main target areas for activities such as geological mapping, geochemistry, geophysics, and structural analysis, all critical for follow-up drilling slated for early summer 2026. Specific objectives include further exploration of the sediment-hosted gold identified in Phase 1, additional sampling at the Union Mine, and structural mapping on-site.
Both Questcorp and Riverside are optimistic about the program's potential to reinforce current findings and to delineate new targets. John-Mark Staude, CEO of Riverside, highlighted the alignment of interests as Riverside holds approximately 9.9% equity in Questcorp, which could rise to 19.9% upon full earn-in completion.
The La Union Project is notable for its various mineralization styles, including carbonate replacement deposits and distinct structurally controlled gold mineralizations. With necessary permits in place and accessible site conditions, the project is well-prepared to advance its exploration and drilling initiatives.
MWN-AI** Analysis
The commencement of Phase 2 exploration at the La Union Project by Questcorp Mining Inc. (CSE: QQQ) and Riverside Resources Inc. (TSXV: RRI) represents a pivotal moment in the exploration of mineral resources in Sonora, Mexico. Following the promising results from Phase 1—including a high-grade 30m channel interval at the Union Mine—this new phase aims to refine existing targets while identifying new opportunities across four key areas. Investors should pay close attention to the implications of these developments as they can significantly affect both companies' stock performances.
Both Questcorp and Riverside are well-positioned for the continued development of La Union, especially given the presence of multiple mineralization styles, such as carbonate replacement deposits (CRD) and newly identified sediment-hosted gold. The strategic focus on sediment-hosted gold targets—similar to Carlin-type systems—may provide avenues for substantial resource growth and value creation. With the program fully funded, the companies will leverage geological mapping and advanced geophysics to refine drill targets.
The integration of the recently consolidated Famosa mineral concessions enhances the operational landscape for Riverside and Questcorp, positioning them to maximize exploration potential. Investors should consider how this district-scale project could contribute to both companies' growth trajectories, particularly in a favorable market for precious metals, which have remained resilient.
Given the increasing interest in gold and silver amidst economic uncertainties, stocks of both Questcorp and Riverside may attract both retail and institutional interest. With a calculated risk approach, entering or adding to positions in either or both companies could be advantageous. However, investors must remain cognizant of the inherent risks involving exploratory mining ventures and the speculative nature of these stocks.

Vancouver, British Columbia--(Newsfile Corp. - April 1, 2026) - Questcorp Mining Inc. (CSE: QQQ) (OTCQB: QQCMF) (FSE: D910) (the "Company" or "Questcorp") along with its partner Riverside Resources Inc. (TSXV: RRI) (OTCQB: RVSDF) (FSE: 5YY0) ("Riverside"), is pleased to announce the commencement of the Phase 2 exploration program at the La Union Project in Sonora, Mexico.
The program builds on the success of the 12-hole Phase 1 drill program announced January 22 2026, which delivered two key results:
- a high-grade 30m chip-channel interval at the Union Mine grading 20.2 g/t gold and 226 g/t silver
- a new sediment-hosted gold discovery at Luis Hill returning 42m grading 0.3 g/t gold.
Field teams have been mobilized across four main target areas, where work will include geological mapping, geochemistry, geophysics, and a property-wide structural analysis in preparation for follow-up Phase II drilling.
"The commencement of our Phase 2 program marks an important step in advancing the La Union Project," said Saf Dhillon, President & CEO of Questcorp Mining. "With a fully funded program now underway, we are focused on systematically refining existing targets while expanding our pipeline of new opportunities across the district. The combination of CRD-style mineralization and the emerging sediment-hosted gold potential at Luis Hill continues to demonstrate the scale and versatility of the project. We look forward to building on these results as we advance toward the next phase of drilling."
Phase 2 Program Objectives
The initial stage of Phase 2 will focus on refining existing drill targets and generating new targets through:
- Follow-up work on sediment-hosted gold ("SHGD") targets identified during Phase 1 drilling, where mineralization was intersected in sedimentary units below the primary CRD host rocks
- Additional underground sampling at the Union Mine, where the previously reported 30-metre interval grading 20.2 g/t gold and 226 g/t silver remains open in both directions
- CRD targeting at the Famosa North area, where lead and zinc anomalies have not yet been drill tested
- Structural mapping in the northern portion of the property, supported by external structural geology consultants
- Continued evaluation of sediment-hosted gold targets in the eastern portion of the project area
- Follow-up exploration at Luis Hill, where Phase 1 drill hole UND25-9 intersected 42 metres grading 0.3 g/t gold in sediment-hosted rocks representing a new style of Carlin-like gold mineralization for this region within Sonora.
Running concurrently with these field activities is an expanded aeromagnetic drone survey, extending coverage across the property. The additional data will support geological interpretation and help refine drill targets in advance of a planned drilling program in early summer 2026.
"We are pleased to have a fully funded exploration program and have immediately activated our team in the field," John-Mark Staude, President and CEO, Riverside Resources Inc. commented. "I have just returned from Sonora, where the Phase 2 program is progressing well, with the Riverside team conducting safe, high-quality work encompassing sampling, mapping, geological targeting, and geochemistry with the aeromagnetic geophysics expansion launching shortly. Building directly on our Phase 1 results, including the high-grade channel sampling at Union Mine and the new sediment-hosted gold discovery at Luis Hill, we have multiple well-defined targets to advance. Riverside is pleased to continue working with partner Questcorp, and as a shareholder in Questcorp, our interests in the success of the Union Project are well aligned."

As announced on March 18, 2026, the Famosa mineral concessions have been formally consolidated into Riverside's land package. This consolidation enhances the Company's district-scale land position and strengthens the foundation for Phase 2 exploration, particularly as mineralization trends extend into key target areas.
The La Union Project hosts multiple district-scale targets and three distinct mineralization styles:
- Carbonate replacement deposit (CRD) mineralization
- Sediment-hosted gold mineralization comparable to Carlin-style systems
- Structurally controlled gold mineralization
With permits in place, site access secured, and contractors engaged, the Company is well positioned to advance toward its next fully funding drilling phase.
