Executive Summary

  • Regulus Resources Inc. has adopted a shareholder rights plan (poison pill) effective March 30, 2026, designed to protect against creeping bids exceeding 20% ownership; the plan requires TSX Venture Exchange approval and shareholder ratification within six months.
  • The company provided an update on the Tantahuatay-AntaKori integrated project, noting that the Mineral Resource Estimate (MRE) completion has been delayed due to disagreements among multiple groups on geological and estimation parameters, though final documentation is underway.
  • Regulus continues to evaluate Nuton LLC’s bio-leaching technologies at AntaKori, with final results expected in the coming months, and is pursuing permits for additional exploration on claims where it can earn up to a 60% interest from Gold Fields Ltd.
