Sentinel Exploration Limited reports it has immediately begun to advance its flagship Marda East Gold Project by commencing a second drilling program on 25 April 2026, the day after successfully completion of its Initial Public Offering (“IPO”) on the National Stock Exchange of Australia (“NSX”).
- Sentinel Exploration Ltd commenced trading on the National Stock Exchange of Australia under the code SOX on 24 April 2026.
- The IPO was oversubscribed, with the Company accepting the maximum raise of $1.5 million.
- The Company has moved immediately to advance its flagship Marda East Gold Project, with a second drilling program commencing on 25 April 2026, the day after listing.
- Marda East is Sentinel’s flagship project and has recently returned encouraging shallow gold intersections, including 3m @ 8.6g/t Au from surface and 3m @ 4.75g/t Au from 48m.[1]
- Sentinel’s broader Western Australian exploration portfolio provides additional discovery upside, including the 100%-owned Cubbine Hills Gold & Copper project and a 30% free-carried interest in Kirup Gold and Lithium.
Sentinel’s Managing Director, Simon Adams, commented:
“The successful completion of Sentinel’s IPO and commencement of trading on the NSX is a significant milestone for the Company and provides a strong platform for our next phase of exploration.
“We thank our new and existing shareholders for their support.
“Importantly, Sentinel has not wasted any time in progressing exploration at its primary project, Marda East, with the Company’s second drilling program commencing immediately after listing. This reflects our clear focus on advancing the project to identify the gold potential with the intention of rapidly adding value to the project.”
Initial Public Offering
The IPO raised $1.5 million through the issue of 7.5 million new shares at an issue price of $0.20 per share. The offer was oversubscribed, with the Company accepting $500,000 in subscriptions above the target raise of $1.0 million.

Completion of the IPO and admission to the NSX represents a significant milestone for Sentinel, providing the Company with the funding platform to accelerate exploration across its Western Australian gold and base metals portfolio.
MARDA EAST GOLD PROJECT – DRILLING COMMENCES
Sentinel’s primary exploration asset is the Marda East Gold Project, a 100%-owned gold project that forms the cornerstone of the IPO investment case.
The project is located on exploration license E77/2689, approximately 80km north-north-east of Southern Cross and close to the Mt Jackson / Marda mining district. Initial geochemical soil sampling exploration work defined two significant soil anomalies, and the first-ever drilling program in this location was completed in Q4-2025, delivering encouraging gold results and established the basis for the imminent follow-up drilling.
The Company’s maiden drilling program at Marda East identified shallow, high-grade gold intersections, including 3m @ 8.6g/t Au from surface and 3m @ 4.75g/t Au from 48m, with 16 of the first 29 RC holes intersecting gold mineralisation.
The maiden 2,200m RC program tested only part of a broader anomalous gold system and supports further infill and extensional drilling.
The Company has moved quickly following listing, with its second drilling program at Marda East commencing on 25 April 2026, immediately after Sentinel’s securities commenced trading on the NSX. The current drilling program is designed to follow up the results from the maiden RC program and further test the broader anomalous gold system identified at Marda East. The program will focus on infill and extensional drilling around areas of known gold mineralisation, as well as testing priority targets generated from previous geochemical and drilling work. A drill rig has been mobilised to site and has commenced an RC drilling program which is expected to be completed within the next month.
Marda East is the Company’s exploration priority and will receive the largest allocation of planned exploration expenditure within Sentinel’s portfolio.
Secondary Exploration Assets
Sentinel’s secondary exploration assets provide additional discovery potential beyond Marda East.
The most advanced of these is the Cubbine Hills Project (Gold and Copper), where Sentinel holds a 100% interest in exploration licences E70/5435 and E70/6600. The project is located approximately 160km east of Perth and around 10km north of Quairading. Exploration completed to date at Cubbine Hills includes electromagnetic surveys, drone magnetics, soil geochemistry and multiple RC drilling programs. Sentinel has identified both gold and copper / molybdenum target styles within the project area.
The Company also holds a 30% free-carried interest in the Kirup Project (Gold and Lithium), together with additional early-stage exploration opportunities at Yamarna, Menzies West and Salway.
Next Steps
Following the successful completion of the IPO and commencement of trading on the NSX, Sentinel’s immediate focus is the execution of the second drilling program at Marda East.
The Company looks forward to providing shareholders with updates as drilling progresses and results become available.
