Gateway Mining Limited (ASX:GML)

Gateway Mining Limited (GML) responded to an ASX Supervision letter dated 14 September 2026 regarding compliance with Listing Rule 15.7 after a conference presentation on 9 September 2026 displayed a slide stating '$45M Placement completed in September' before ASX had released the related market announcement. GML confirmed the presentation began shortly after 9:00am AEST and ended around 9:20am, and acknowledged the relevant slide was likely shown at about 9:18am, before the placement announcement was released on the ASX Market Announcements Platform at 9:35am and before the presentation itself was released at 9:58am. GML stated the presentation had been reviewed and authorised by the Executive Chairman and was largely the same as a 3 September 2026 presentation except for the added placement completion reference. The company expressly accepted that showing the slide before ASX release was not compliant with Listing Rule 15.7, explaining that a slight delay in finalising the announcement for lodgement meant the CEO started presenting believing the announcement would already have been released, and that there was no practical opportunity to intervene once the presentation had commenced. GML noted that no market trading occurred during the gap because ASX normal trading had not started and the company remained in a trading halt, although it accepted this did not remove the breach. GML outlined its existing continuous disclosure policy, under which the Company Secretary acts as Responsible Officer and presentation materials are reviewed and intended to be lodged on MAP before or at the same time as external release, and committed to enhanced controls including requiring confirmation that ASX has released an announcement before any price-sensitive presentation is given, live monitoring of MAP around presentation times, extra scheduling buffer before conference presentations, and a board review and possible update of the continuous disclosure policy. GML also confirmed that its response to ASX was authorised and approved by the board.
