Quarterly Activities/Appendix 5B Cash Flow Report 25 pages 3.7MB
Interim / Quarterly Report Classification · 95% confidence The document is a 'Quarterly Activities Report' for Great Southern Mining for the period ended 31 March 2026. It details operational activities, exploration results (drilling programs, assay results), and corporate updates (equity placement, cash position). While it contains financial data (cash balance, capital raise), it is primarily an operational and exploration update rather than a comprehensive financial statement (10-K or IR). In the context of mining companies, these 'Quarterly Activities Reports' are standard operational disclosures. Since it provides substantive operational and financial analysis for a specific quarter, it fits the definition of an Interim/Quarterly Report (IR). Q3 2026

Edinburgh Park Exploration Update 13 pages 1.6MB
Regulatory Filings Classification · 85% confidence The document is an ASX announcement from Great Southern Mining providing an exploration update (Edinburgh Park), detailing drilling plans, JORC Code technical reporting and forward‐looking statements. It is not a financial report (not an Annual Report, Interim Report, Earnings Release, etc.), nor a meeting, governance, capital market, or other specific category. It is a general regulatory announcement on the ASX that does not fit more specific categories, so falls under the general Regulatory Filings category (RNS).

Proxy Solicitation & Information Statement Classification · 100% confidence The document is titled 'Notice of Meeting and Proxy Form' for an Extraordinary General Meeting (EGM) of Great Southern Mining Limited. It includes detailed information about the meeting arrangements, agenda items (such as ratification of prior share issues and approval of related party participation), proxy voting instructions, and an explanatory statement. The document is a formal notice sent to shareholders to inform them about the upcoming EGM and to solicit their votes via proxy forms. It does not contain financial statements, audit results, earnings data, or management discussion and analysis. It is not a report but a meeting notice and proxy solicitation document. Therefore, the appropriate classification is Proxy Solicitation & Information Statement (PSI). The document length (15,000 characters) and content confirm it is the actual notice and proxy form, not just an announcement of a report.

Diamond Drilling Commences at Golden Boulder - Updated 9 pages 1.3MB
Capital/Financing Update Classification · 95% confidence The document is an ASX announcement dated April 7, 2026, providing an update on diamond drilling activities at the Golden Boulder discovery by Great Southern Mining Limited. It includes detailed commentary on drilling programs, geological observations, preliminary logging, and expected assay results. The content focuses on exploration updates, drilling plans, and technical geological data rather than financial results, management changes, or regulatory certifications. The document is lengthy (15,000 characters) and contains substantive operational information but does not present financial statements or earnings data. It is clearly an operational update related to exploration activities, typical of a Capital/Financing Update or exploration progress announcement. Given the focus on drilling updates and co-funding by the Western Australian Government's Exploration Incentive Scheme, and the absence of financial results or management changes, the best fitting category is Capital/Financing Update (CAP).

EIS FUNDED DIAMOND DRILLING COMMENCES AT GOLDEN BOULDER 7 pages 1.2MB
Capital/Financing Update Classification · 95% confidence The document is an ASX announcement dated 31 March 2026 from Great Southern Mining Limited (GSN) detailing the commencement of diamond drilling at the Golden Boulder discovery within their Duketon Gold Project. It includes highlights of the drilling program, geological context, previous drill intercepts, and plans for further drilling. The document also mentions co-funding from the Western Australian Government Exploration Incentive Scheme (EIS) and provides technical details about the drilling program. There are no financial statements, quarterly or annual results, or management discussion of financial performance. The content is focused on exploration activities and operational updates rather than financial reporting or governance changes. The document is a typical exploration update announcement intended for investors and the market, describing ongoing and planned drilling activities and exploration results. It does not fit categories like Annual Report, Interim Report, Earnings Release, or Management Reports. It is not a regulatory filing or legal proceeding update. It is not a capital raising announcement per se, although it mentions a recent equity capital raising as background. The best fitting category is a Capital/Financing Update (CAP) because it includes information about the company's exploration program funded by a recent equity capital raising and government co-funding, which is a financing-related update tied to capital deployment. The document length (over 14,000 characters) and detailed content confirm it is a substantive announcement, not just a brief notice or report publication announcement.
