Bumi Resources stock adds Queensland copper-gold exposure

PT Bumi Resources has expanded beyond its established coal operations by completing the purchase of Mount Margaret Mining in Queensland. Mining.com.au reported on October 26 that Bumi Resources Australia, a wholly owned subsidiary, completed the acquisition on October 23, 2026.

Bumi Resources Australia acquired all issued shares in Mount Margaret Mining for 22.01 million US dollars. The transaction gives the Indonesian resources company exposure to the Mount Margaret Copper-Gold Project, which comprises the E1 and Monakoff deposits about 39 kilometres northeast of Cloncurry.

Project Adds Copper And Gold Exposure

Mount Margaret has a previous open-pit mining history from 2012 to 2014, when ore was transported to the nearby Ernest Henry processing facility. A 2022 project presentation cited an open-pit resource of 13 million tonnes grading 0.78 percent copper and 0.24 grams of gold per tonne.

Those historical figures provide geological context rather than a current production forecast. Bumi has not disclosed an updated resource estimate or a development timetable for the project. Future revenue and cash flow will therefore depend on exploration results, technical work, investment and any decision to advance the asset toward production.

Execution Becomes The Next Test

Director RA Sri Dharmayanti described the acquisition as a strategic step in Bumi's transformation plan and business diversification program beyond coal, according to Mining.com.au. The purchase follows Bumi's move to acquire Loyal Metals and its Australian copper-gold portfolio, extending a broader minerals strategy alongside the group's coal operations.

Bumi Resources stock traded at 0.01 euros on Lang & Schwarz at 09:34 CET on Thursday, November 12, 2026. Investors will focus on whether Bumi can convert its Australian acquisitions into defined resources, development plans and operating earnings while controlling the funding and execution risks of the expansion.

Indonesia's broader market remains the backdrop for current market reports.
