Riverside Resources (OTCQB:RVSDF) and partner Questcorp completed an expanded aeromagnetic drone survey at the La Union Project in Sonora, Mexico. The 2026 work adds 145 flight lines (193 km) plus 55 km of tie lines, for 248 km of total coverage.
The data, integrated with detailed geologic and structural mapping and high-grade Phase 2 sampling, is refining drill targets ahead of a fully permitted summer 2026 Phase 2 drill program, with drill roads, pads, and contractor arrangements already underway.
Riverside Resources (OTCQB: RVSDF) reported Phase 2 field results from the La Union Project, Sonora, Mexico, including high‑grade channel and selective samples. Highlights include a 2.9 m channel averaging 20 g/t Au (incl. 0.6 m at 91.7 g/t Au), a 0.3 m interval at 40% Zn, and Union Norte hits such as 1.0 m @ 4.38 g/t Au, 1,413 g/t Ag, 7.7% Pb, 6.38% Zn. Three new targets (Jabali, La Negra, Ali Hill) were defined and a summer 2026 drill program is planned with permits and contractor secured.
Riverside Resources (OTCQB: RVSDF) has begun a fully funded Phase 2 exploration program at the La Union Project in Sonora, Mexico, sponsored by Questcorp. Phase 2 expands mapping, geochemistry, geophysics and structural studies across four target areas and follows Phase 1 drilling that returned 42m @ 0.3 g/t Au at Luis Hill.
Permits, site access, a drill contractor and geophysics provider are in place, and an expanded aeromagnetic drone survey will guide a planned early-summer 2026 drilling campaign. Famosa concessions were consolidated into Riverside's land package on March 18, 2026.
Riverside Resources (OTCQB: RVSDF) completed consolidation of the Famosa Area within the Union Project, acquiring three mineral concessions (La Famosa, Dana 7, Dana 7) via final payment and title transfer to its Mexican subsidiary.
The transaction totals US$175,000 (final payment US$125,000), conveys fully titled concessions with validity through 2044–2053, and carries no net smelter royalty on these claims. Riverside continues district exploration with partner Questcorp, which may fund up to C$5.5 million in exploration while Riverside retains a 2.5% NSR on the broader project.
Riverside Resources (OTCQB: RVSDF) reported early 2026 exploration at the 100%‑owned Ariel Copper Project, Sonora, Mexico, highlighting high‑grade rock samples including 320 g/t Ag and 5.39% Pb, consolidated 1,640 hectares, drill‑permitted status, porphyry targets with Paleocene (~57 Ma) intrusions, and readiness for partnering and drill testing.
Work included mapping, chip sampling, spectral alteration studies, geophysics integration and QA/QC with ACT Labs and Bureau Veritas analyses.
Riverside (OTCQB: RVSDF) and Questcorp announced surface chip-channel and Phase 1 drill results from the Union Project, Sonora, dated January 22, 2026. A 30 m continuous chip-channel returned 20.2 g/t Au, 226 g/t Ag and 2.7% Zn in the oxidized upper Union Mine adit. Phase 1 drilling (12 holes, ~1,600 m) reported gold intersections across six targets and CRD-style base-metal signatures (Zn, Ag, Pb) at Union Mine, Union Norte and El Cobre. Questcorp also reported Luis Hill discovery: 42 m at 0.3 g/t Au in black shales, indicating sediment-hosted (Carlin-like) potential. Follow-up Phase 2 drilling planned H1 2026.
Riverside Resources (OTCQB: RVSDF) doubled the size of its Jacket property by optioning the adjacent Redtop claims to create the Red Jacket Project in central British Columbia. Riverside completed late-2025 sampling that returned high-grade surface grab assays (up to 24% Zn, 217 g/t Ag, 1.1% Pb, and 0.8 g/t Au) across a 4 km prospective VMS horizon. The option requires $180,000 cash and $750,000 cumulative exploration spend staged after drill-permit approval, and grants the vendor a 0.45% NSR (buyout $1,000,000). Further drill permitting and H1 2026 work are planned.
Riverside Resources (OTCQB: RVSDF) outlined its 2026 corporate outlook and reviewed 2025 milestones, highlighting a C$3.7 million non-brokered private placement, a 93 million share capital base and no debt. Key 2026 priorities include advancing Canadian gold and REE projects (Red Jacket, Revel, Deer Park), completing assays and follow-up at the Union Project under a Questcorp option (up to C$5.5M in partner funding), advancing Cecilia after positive 2024–2025 drilling, growing its royalty portfolio (2% NSR on Tajitos and Sugarloaf Peak) and disciplined capital deployment. Riverside completed a Blue Jay Gold spin-out in 2025, received 6,285,722 Questcorp shares (9.9%), and finished a partner-funded Phase 1 drill of 12 holes (~1,600+ m) at Union with assays pending.
Riverside Resources (OTCQB: RVSDF) completed Phase 1 drilling at the Union Project, Sonora with 12 diamond core holes totaling >1,600 metres across six priority targets (Union Mine, Union Norte, Cobre, Luis, Famosa, Famosa Mag).
>700 half-core samples have been shipped to Bureau Veritas and ACT Labs for gold fire assay and multi-element ICP-MS; assays are pending. Drilling targeted shallow CRD-style manto and feeder horizons generally <150 m depth. Work was funded by partner Questcorp under an option agreement with Riverside as operator.
Company plans to integrate assays, geophysics and mapping to refine the model and scope a Phase 2 drill campaign, potentially in H1 2026.
Riverside Resources (OTCQB: RVSDF) expanded its rare earth elements (REE) program on October 14, 2025, prioritizing work at the Revel Project in southern British Columbia and generating additional targets in Canada and Mexico. Riverside identified an extensive carbonatite unit at Revel and plans staged work including detailed mapping, spectral and geochemical sampling, ground geophysics, and baseline/permit planning to enable first-pass drilling. The company said it will advance targets via its project-generator model, seeking partners, options, or spinouts while retaining equity or royalties. Blue Jay Gold share distribution occurred in May 2025 at a 5-for-1 ratio.
