RVSDFQQCMF
  • Riverside Resources Inc. & partner Questcorp Mining Inc. completed expanded geophysical programs at the La Union Project in Sonora, Mexico, linked to current drilling efforts.
  • The programs included a completed aeromagnetic drone survey with processed data received for integration into the summer core drilling phase.
  • An Induced Polarization (IP) ground geophysics survey was also completed, with processed results expected soon to identify expansions & additional targets.
  • Geophysical data is being applied to three active drill areas: Union, Union North, and Jabali.
  • The aeromagnetic survey covered 248 km across 202 flight lines at 100 m spacing, building on a 2025 baseline dataset.
  • New data reveals cross structures trending NE & NW that potentially coincide with mapped feeder fault zones for Carbonate Replacement Deposits (CRD).
  • Improved imaging identified new NW-trending structures beneath post-mineral cover that have never been drilled before.
  • Drilling has been completed at Union & Union North targets, while the Jabali target remains actively drilled.
  • The IP survey consists of 5 lines that integrate with magnetic data to define current drill targets & broader expansion areas.
  • QA/QC for surface geochemistry involved rock samples analyzed at ACT Labs in Zacatecas using fire assay & 4-acid digestion ICP/EOS methods.
  • Riverside Resources Inc. maintains a strong balance sheet with over C$5,000,000 cash, no debt, & a portfolio of gold-silver, copper, & REE assets.
  • The Union Project hosts historical mining areas associated with gold, silver, zinc, & lead mineralization within carbonates.
  • Freeman Smith, P.Geo., the Company's Vice President Exploration, reviewed & approved the technical content of the release.
