MGX Resources and joint venture partner Tanami Gold took a significant step toward development of the advanced high-grade Central Tanami Gold Project (CTPJV) this week with the selection of Macmahon Underground Pty Ltd (a subsidiary of Macmahon Holdings Ltd) as Preferred Contractor to develop an underground exploration decline at the high-grade Groundrush gold deposit. The exploration decline is an important component of the CTPJV’s development activities which will facilitate resource infill drilling of the deposit from underground headings and enable early advancement of the decline workings. Macmahon’s scope of work will include portal and vent establishment and approximately 3,500 metres of exploration decline development. Activities are expected to commence in the September 2026 quarter and extend for a 14 month period, with the work valued at approximately $38 million. Underground drilling activities will commence towards the end of this period. The appointment of Macmahon remains subject to finalisation and ex*****on of a binding
