SnapshotThe Munglinup project is on a mining lease granted until 2031 within a designated mining reserve.

Obtaining environmental approvals and advancing studies remain the priorities for the Munglinup graphite development and are expected to be achieved by the December 2025 quarter, following some delays in the process.

The Munglinup Graphite Project remains a crucial asset in the Mineral Commodities' overall goal to supply natural graphite into the key high-demand battery anode markets, with the DFS (2020) outlining a graphite asset able to produce approximately 52,000tpa of ore over 14 years at an average grade of 12.8%.

It is Mineral Commodities's strategy to reposition the Company as being focused on graphite only, with integrated assets.

The Munglinup Graphite Project is a joint venture between MRC Graphite Pty Ltd (MRCG) and Gold Terrace Pty Ltd (Gold Terrace). MRCG is operator of Project.

MRCG is a wholly owned subsidiary of Mineral Commodities Ltd. (MRC). The MRC holds an existing 51% interest in Munglinup.

During 2024, negotiations were undertaken to secure terms for MRC to increase its share in the Project. As a result, the MRC announced on 25 June 2024 that its wholly owned subsidiary MRCG had reached an in-principle agreement with Gold Terrace to settle a dispute and acquire the remaining 49% interest in Project.

The total consideration to be paid to Gold Terrace in exchange for its 49% interest in Project is $A7.5M in cash.

Upon acquiring the remaining 49% interest, the MRC will become the 100% owner of Munglinup.

As at March 2025, the Formal Agreement has not yet been executed.

Summary:

The graphite deposits are located in the northern foreland of the AlbanyFraser Orogen and are hosted by paragneisses of the Munglinup Gneiss. Structurally the prospect is located adjacent to the intersection between the northeast trending Fraser Range Fault and the northwest trending Merredin Fault.

The Munglinup graphite deposits occur as discrete layers in a zone of graphitic schists within a sequence of hornblende and hornblende-garnet gneisses. The rocks have been broadly folded about a WNW/ESE axis, with superimposed minor anticlinal and synclinal flexures. Complex small-scale folding and faulting is common in the relatively incompetent graphitic rocks and the enclosing competent hornblendic gneisses appear to be less deformed.

Targeted graphitic mineralisation occurs within saprolite consisting of clays, quartz, graphite (up to 42% flake) and goethite. Weathering extends down to at least 60m.

The host geology comprises weathered metamorphic material.

The Munglinup area comprises Archean to Paleoproterozoic, metamorphosed granitic and other metamorphic rocks of the Albany–Fraser Orogen, typically hornblende (± garnet) gneiss and migmatite.

Within the gneissic rock mass, rocks containing the Munglinup graphite deposits consist of a succession of tightly folded metasedimentary rocks with a consistent dip from north north east to the south.

The classification scheme most widely accepted for graphite deposits was introduced by Cameron (1960). It classifies known graphite deposits into five categories reflecting the different types of graphite.

Using this classification scheme, it is most likely that the Munglinup deposit
can be characterised as a type 1, disseminated flake graphite in silica-rich meta-sediments deposit.
