Sentinel Exploration Limited welcomes increased gold exploration activity in the Southern Cross region, as the Company’s second drilling program continues at the Marda East Gold Project.

“Strong gold exploration activity continues to build across the Southern Cross region, reinforcing the importance of this part of Western Australia as an active and highly prospective gold exploration district,” Sentinel Exploration Managing Director Simon Adams commented.

With Sentinel’s second program at its Marda East Gold Project continuing to progress, Adams pointed to a recent Mining.com.au feature on Golden Horse Minerals which highlights the scale of work being undertaken across the Southern Cross Greenstone Belt.

“This regional momentum is encouraging, with substantial drilling programs, tenure consolidation and renewed market attention from companies in the same region as Sentinel,” Mr Adams continued.

Sentinel’s flagship Marda East Gold Project sits within the Southern Cross region, where the exploration team is continuing to advance follow-up drilling after encouraging shallow gold results from the initial program in late 2025, including:

🟨 3m @ 8.6g/t gold from surface
🟨 3m @ 4.75g/t gold from 48m

Sentinel remains focused on systematically testing and advancing Marda East, with drilling designed to build on the results already delivered, and assess the project’s broader potential.

Also in the new last week, Leeuwin Metals Ltd commenced a high impact 5,000m RC drill program at its Marda Gold Project in WA, with Leeuwin’s program is designed to test extensions of their existing 342,300oz gold mineral resource at Marda.
