RC Drilling underway 6 pages 1.2MB
Regulatory Filings Classification · 95% confidence The document is an ASX announcement dated 24 June 2026 from Great Southern Mining Limited. It details the commencement of Reverse Circulation (RC) drilling programs at the Mon Ami Gold Project and other exploration projects. The text includes descriptions of drilling targets, maps, and exploration prospects. There are no financial statements, detailed financial performance data, or comprehensive management analysis. It mostly communicates operational updates and exploration activities, typical of announcements relating to ongoing projects or operational updates. This type of text fits the profile of a general Regulatory Filing (RNS) as a standard ASX announcement about exploration progress without constituting an annual, interim, or earnings report, nor other more specific categories like M&A, capital changes, or management changes.

Change of Director's Interest Notice 3 pages 539.7KB
Director's Dealing Classification · 100% confidence The document is titled 'Appendix 3Y Change of Director's Interest Notice' and includes detailed information about a director's acquisition of shares and interests in the company. It explicitly refers to changes in director's relevant interests in securities, including dates, amounts, and nature of the trades. The document references ASX Listing Rule 3.19A.2 and section 205G of the Corporations Act, which are typically related to insider or director shareholding disclosures. This is not a general report or financial performance disclosure but a specific notification about a director's personal share transactions. Therefore, it fits the definition of 'Director's Dealing (DIRS)', which involves reports of personal share transactions by company directors and executives (insider trades). The document length and content confirm it is the actual report, not an announcement or certification, so it should not be classified under regulatory filings or announcements.

Major drill programs commencing to advance gold discoveries 21 pages 2.3MB
Capital/Financing Update Classification · 95% confidence The document is an ASX announcement from Great Southern Mining regarding the commencement of a major drilling program to advance gold discoveries. The text extensively covers geological details, drill program plans, prior intercept results, targets for extension of mineralisation, and strategic considerations for the projects. It highlights multiple drilling sites and technical mineral exploration results with geological interpretations. There is no indication this document is a full financial report like an Annual Report (10-K) or an Interim/Quarterly Report (IR). Nor does it contain initial quarterly results that would classify it as an Earnings Release (ER). It is also not a Board or Management change announcement, call transcript, or any kind of legal or financing update. The main focus is on exploration updates and project development drilling activities, consistent with a capital project or financing update in the mining sector context. Although not directly about fundraising, the announcement stresses that the company is fully funded for the drilling campaign after a recent equity placement, which is a financing-related update. It is not merely a report publication announcement since it contains detailed operational news and data on the drilling programs and results. Given all these characteristics, the best fitting filing category is Capital/Financing Update (CAP). The confidence is high due to the document's content length, detailed drilling and funding status information that align best with CAP rather than other types.
