Westgold set out FY2027 guidance and a three-year production plan on 9 September 2026, stating gold production of 385,000–425,000 ounces in FY2027 and 460,000–510,000 ounces in FY2029. Westgold attributes the increase to expanded processing capacity and continued development of its existing mines. The ranges are the company’s own estimates for periods that have not begun.
A 400 oz Good Delivery bar is variable in weight across the 350–430 oz range at a minimum fineness of 995.0, and the figures that govern an individual bar are its stamp and its line on the weight list. Kilobars and the cast and minted formats below them are produced to fixed weight at 999.9 and are specified by refiner mark, with Heraeus and Argor-Heraeus SA among the marks on the LBMA Good Delivery List. Contained ounces at a mine appear in neither specification: output leaves site as doré, which carries no mark, no serial number and no assay certificate, and reaches an institutional format only after refining and assay by an accredited refiner. Acceptance under the Good Delivery Rules follows the refiner’s listing at the time of production, so a bar’s standing is read from its mark and its assay rather than from the mine behind it. Where an expanded source enters an accredited refiner’s feed, it enters through that refiner’s due diligence under the LBMA Responsible Gold Guidance and the OECD Due Diligence Guidance, and a source-of-metal file is assembled from that documentation. FY2029 also sits beyond the term of a purchase instruction, and what can be allocated by serial number on a given date is what a refiner has already cast and holds on that date.
Westgold’s plan covers its own operations. Good Delivery weight and fineness rules, and the accreditation of the refiners casting to them, are set and recorded by the LBMA.
