Projects in Western Australia
Sentinel Exploration Limited owns projects in geographically diverse domains in Western Australia.
Exploration is at an early stage at all projects, but substantial investigatory investment and field effort has been expended by Sentinel to date.
All projects demonstrate significant upside for pontential economic mineralisation including Gold, Copper, Moly, Silver and Lithium.
Sentinel’s Projects:
- Marda East
- Cubbine Hills
- Yamarna
- Menzies West
- Salway
- Kirup
- Tampia North

Flagship Gold Project
Marda East (100% owned) is located 12 km East of the ex-Ramelius’s Marda Gold project and 80km NE of Southern Cross WA (Ramelius Marda project resources: 2,900,000t @1.6 g/t for 140,000 oz, June 2022).
Virgin Gold Discovery 30m @ 1.12g/t Gold from 12m at Marda East – July 2026.
Sentinel Exploration reported a virgin gold discovery: 30m @ 1.12g/t Gold from 12m in drilling results from the Company’s flagship Marda East Gold Project.
- Shallow composite result of 30m @ 1.12g/t gold from 12m depth in drillhole 26MERC057, including:
- 3m @ 5.35g/t gold from 15m and;
- 3m @ 3.59g/t gold from 36m;
- 3m composite assays from Sentinel’s second RC drilling program at Marda East, (90km North of Southern Cross), have been received and reviewed, comprising 33 holes for 2,915m;
- Diamond drilling followed, with the program to twin hole 26MERC057 in August 2026.
Results from maiden drill program at Marda East – December 2025.
The Company completed 29 RC drill holes to an average depth of approximately 78m.
This formed part of a 2,200m maiden drill program, representing the first ever drilling campaign undertaken on this prospect. This target was generated by our technical team using soil geochemistry, which revealed a compelling gold-arsenic anomaly extending across two strike zones of 450m and 750m, coincident with magnetic features.
Results included:
- 3m @ 8.6g/t gold from surface;
- 3m @ 4.75g/t gold from 48m;
- 6m @ 1.65g/t gold from 12m.
- 6m @ 1.51g/t from 51m.
These were 3m composite samples. Management are encouraged and are now working on full analysis of multi-element and 1m samples, when received, to design the next program to advance the understanding of this new gold system.
With these results, Marda East becomes our flagship project, and will be the main focus of our drilling in the year ahead, towards gold resource definition.
Follow up drilling commenced at Marda East in late April 2026, following the successful quotation of the Company on the NSX.
