REPEAT - Gold and Antimony in One Permit: Rua Gold's Positive PEA Lands in a Fast-Track Jurisdiction

Rua Gold advances its Auld Creek gold-antimony project in New Zealand following a positive preliminary economic assessment and fast-track permitting.

Executive Summary
  • The most recent release (June 8, 2026) is a repeat/update of the Preliminary Economic Assessment (PEA) for the Auld Creek Gold-Antimony Project, originally announced on May 5, 2026.
  • The PEA outlines a 5.5-year underground operation processing 250,000 tonnes per year, producing separate gold and antimony concentrates.
  • Economics: After-tax NPV5% of ~US$42 million at base-case prices ($3,300/oz Au, $27,000/t Sb) and ~US$113 million at spot gold prices ($4,700/oz Au).
  • Production: ~27,000 gold-equivalent ounces annually, with 95% gold and 85% antimony recovery on a no-cyanide flowsheet.
  • Permitting: A Fast-Track Referral application was filed on April 20, 2026, under New Zealand's accelerated regime. Full permitting is targeted for Q2 2027.
  • Drilling: A 19,000-metre infill and step-out program is underway to convert Inferred resources to Indicated/Measured and extend mineralization.
  • Timeline: PFS targeted for Q4 2026, with production targeted for 2028.
Material Impact
  • The news is a routine follow-up to the May 5 PEA. The core economic metrics, mine plan, and permitting status remain unchanged.
  • The Fast-Track Referral filing in April 2026 was already disclosed in prior updates. The June 8 release reiterates the positive PEA and drilling progress.
  • No new material financial or operational surprises are introduced. The market had already priced in the PEA and permitting progress.
  • The dual-metal exposure to gold and structurally short antimony supply remains a key strategic theme, but this is consistent with previous guidance.
  • Impact is incremental and expected, aligning with the company's stated development roadmap.
