1 million ounce high-grade gold resource at Side Well 44 pages 3.0MB
Capital/Financing Update Classification · 95% confidence The document is an ASX announcement dated 18 December 2025 from Great Boulder Resources regarding an updated Mineral Resource Estimate (MRE) for the Side Well Gold Project. It contains detailed mineral resource data, including tonnage, grade, and ounces of gold for various deposits, as well as geological and drilling information. The document is a comprehensive update on the mineral resource status and exploration results, not a financial report, earnings release, or management discussion. It is not a notice of voting results, board changes, or legal proceedings. The content is focused on mineral resource estimation and exploration progress, typical of a capital/financing update or resource update announcement. Given the nature of the content and the ASX announcement format, this fits best under Capital/Financing Update (CAP), which includes updates on company assets and resource estimates relevant to capital and project valuation. The document length is substantial and contains substantive data, so it is not a mere announcement of a report (RPA) or a regulatory filing (RNS).

The content focuses on exploration results and project updates rather than financial results or regulatory compliance. There is no indication that this is a full annual or interim financial report, audit report, or earnings release. It is not a call transcript, management change announcement, or legal proceeding. The document is a detailed operational update typical of exploration companies announcing drilling results and project progress to investors and the market. This fits best under the category of a Capital/Financing Update (CAP) as it relates to exploration progress and resource potential, which are material to the company's capital market valuation and financing considerations. The document length (15,000 characters) and detailed content confirm it is not a brief announcement or a report publication notice. Therefore, the most appropriate classification is CAP with high confidence.
