Riverside, Questcorp Complete Geophysics, Continue La Union Drilling
Tap title to read story
Vancouver — Riverside Resources and partner Questcorp Mining announced on July 9, 2026 the completion of expanded aeromagnetic drone and induced polarization (IP) ground geophysics programs at the La Union project in Sonora, Mexico, and the integration of processed aeromagnetic data into the ongoing summer core drilling campaign targeting Union, Union North and Jabali.
On July 9, 2026 companies reported that data processing is underway for IP results and that the geophysical datasets — including 248-line kilometres of drone magnetics and additional IP lines beyond 2025 coverage — will be applied this week to refine drill targets, expand identified targets, and guide potential strike- and depth-extension drilling.

Timeline
- 1. 2025: Baseline geophysics dataset assembled and 4-line kms of IP were completed.
- 2. 1H 2026: Surface program defined new target areas prior to drilling.
- 3. July 9, 2026: Companies announced completion of expanded aeromagnetic drone and IP surveys.
- 4. July 2026: Processed aeromagnetic data received and integrated into summer core drilling.
- 5. July 2026: IP data processing ongoing to expand targets and guide additional drilling.
Why it matters
Riverside and Questcorp's expanded geophysics programs could lead to more efficient mining. This means potentially lower costs for materials like copper and gold. Keep an eye on prices in the coming months.
