About Augustus Minerals Limited

Augustus Minerals is an ASX-listed explorer that acquired ACM PNG in 2025. ACM PNG was registered in Papua New Guinea in 2014 and holds two exploration licence applications: ELA2446 over the Mt Kare Gold Project, and ELA2955 over the Vanapa River region. The company also lists Music Well and Ti-Tree among its projects.

Mt Kare Gold Project application

Mt Kare is described as an alkali epithermal gold deposit, about 15 kilometres from the Porgera Gold Mine in Enga Province. The company notes that this class of deposit includes Porgera, Lihir, Cadia-Ridgeway and Cripple Creek.

The announcement sets out the status of the application. A first-in-time applicant was removed from the list by the Mineral Resources Authority at the order of the PNG Supreme Court on 30 May 2025, after which private company Tribune Mt Kare Gold Limited moved to first-in-time and ACM PNG to second-in-time. Applications are assessed in order. The company states that, because the application has not been granted and is contested, ACM PNG does not currently have an actual or contingent right to undertake exploration and development, and there is no guarantee that a licence will be granted.

Vanapa River and regional setting

ELA2955 covers the Vanapa River region, about 40 kilometres from the Tolukuma Gold Mine and 35 kilometres north of Port Moresby. Both projects sit within the 2,300 kilometre New Guinea Metallogenic Belt, which hosts deposits such as Frieda River, Porgera, Kainantu, Hidden Valley and Wafi Golpu.

Activities during 2026

During 2026 ACM PNG purchased all available open-file data on Mt Kare from the PNG Mineral Resources Authority and compiled a Technical Information Memorandum covering historical exploration, geology, mineralisation style and historical resource estimates. Executives attended a political party foundation dinner at the invitation of the Enga Provincial Governor, and ACM PNG assisted with the purchase and delivery of humanitarian supplies to help Mt Kare landowners return to the village.

Site awareness and landowner meetings have continued with clans from the Enga, Hela and Central provinces during 2025 and 2026. The proposed work program in the original application included an underground portal, decline development, underground diamond drilling and feasibility studies.

Sector backdrop

Papua New Guinea hosts several large gold and copper operations and projects, and applications for exploration licences are assessed by government bodies in order of application. Resource projects in the country generally involve landowner agreements, community engagement and lengthy approvals.

Gold projects in remote areas often require significant infrastructure and Capital before production can start.

Risks shareholders should weigh

The most prominent risk is that the Mt Kare application has not been granted and is contested, as the company itself states. If the licence is not granted to ACM PNG, the company would not hold the right to explore the project.

The company has not yet undertaken drilling on Mt Kare, and the historical resource information is not a current estimate. Funding for any program would likely require capital raisings. Political and landowner factors in Papua New Guinea can affect timelines. With a price of $0.029, the 21.62% fall on 20 October 2026 illustrates how sharply small-cap prices can move.

What’s next

The announcement did not set dates. Future steps depend on the assessment of ELA2446 by the Mineral Resources Authority and the Mining Advisory Council, continued landowner engagement, and the status of the Vanapa River application.
