Redcastle drilling to confirm potential for “string of pearls” style gold at WA project

• RC1 to kick off 2700m drill program in November at Morgan’s Castle East and Sligo
• Program will share logistics with RC1-BML JV to cut costs and boost efficiency
• Drilling could define maiden resource at MCE, confirm more deposits present along trend

Special Report: Redcastle Resources will launch a ~2700m reverse circulation drill program in November to test priority gold targets at its namesake project in WA’s prolific Eastern Goldfields.

The program will test targets at Morgan’s Castle East (MCE) and Sligo along the east–west mineralised corridor that also encompasses the Queen Alexandra and Redcastle Reef deposits

Notably for Redcastle Resources (ASX:RC1), this drilling will be coordinated with ongoing work at the Queen Alexandra and Redcastle Reef deposits that are being fast-tracked to development under a joint venture with BML Ventures (RB JV).

It will build on the January 2025 drill program that confirmed the presence of a high-grade gold system at MCE.

Sharing logistics and infrastructure with the RB JV will also maximise operational efficiency and reduce costs.

“This upcoming ~2700m RC drilling program, due to commence in November, highlights the pace and cohesion that’s developed within the RB Joint Venture since announcing our first meeting in September 2025,” RC1 non-executive chairman Raymond Shaw said. 

“It’s pleasing to see the JV already moving into coordinated field execution. The immediate focus will be at MCE, where tightening geological control could open the way for a future development alongside the QA and RR prospects. 

“At the same time, RC1 as part of the overall program, will be stepping out to the east to test the Sligo target — part of our further proof-of-concept for a ‘string-of-pearls’ style corridor of mineralisation. 

“Combining the RB JV and RC1 programs under one capital-light campaign reflects exactly the disciplined and collaborative approach the company set out to achieve.”

Drill program

The new drill program will consist of 2200m at MCE and 500m at Sligo.

It is aimed at increasing the geological knowledge at MCE and collect the data required to potentially support an initial JORC resource.

MCE’s potential use as a supplementary ore source alongside Queen Alexandra and Redcastle Reef is subject to drilling outcomes, technical studies, and regulatory approvals.

Gold mineralisation at MCE trends east–west and dips moderately to the north beneath cover, correlating with extensions of the mineralised corridors noted in February 2024.

The prospect lies within MLA39/1140 – a tenement that forms part of the RB JV.

Final drilling schedule here might be adjusted to coordinate with the upcoming RB JV drilling campaigns.

Meanwhile, the Sligo target area to the east of MCE represents an opportunity to extend the mineralised corridor.

RC1’s mining licence application MLA39/1170 notes that eluvial/alluvial gold occurrences – including gold nuggets at surface – are present.

Specialised reprocessing of Landsat imagery and aeromagnetic data, together with geological mapping was used to enhance structural interpretation and define high-priority zones for testing that have no surface expression.

Limited rotary airblast drilling has identified anomalous gold mineralisation within the margin of the interpreted mineralised corridor, highlighting potential for “blind” gold-hosting structures beneath cover.

The company has also built an inventory of other prospects along the east–west mineralised trend.

Of these, Coronation, South Queen and Battery Lode stand out as other prospective drill targets as they are proximal to the same interpreted mineralised corridor as Queen Alexandra, Redcastle Reef and MCE.

They also have sufficient surface geological control, historical activity and/or geochemical support to allow rapid program design and permitting.

Additionally, all prospects are within a logistically convenient distance of the planned RB JV operations.
