SnapshotThe Saint Elmo Project aims to mine vanadium and process vanadium pentoxide, HPA and other critical mineral products.

Key project facts
- Multicom Resources has entered the project execution phase, with construction having commenced late 2023.
- The Saint Elmo Project is fully permitted with mining leases and environmental authorities.
- In February 2020, the Queensland Government declared Saint Elmo as a ‘Prescribed Project’.
- Multicom Resources completed a detailed feasibility study for the project and built a pilot plant in Perth (Western Australia) that produced products for marketing purposes.

Since Multicom is a private company, technical documents are not available in the public domain.

Summary:

The Project area contains sediments of the Eromanga Basin, a marine basin that formed between the Late Triassic to Early Late Cretaceous. MLA100162 contains sediments deposited in the Late Early Cretaceous, comprising the Toolebuc Formation, and the overlying Allaru Mudstone (Resolve 2018). No subsidence has been noted at the site.

Underlying the Toolebuc Formation is the Wallumbilla Formation, the most widespread marine unit within the Eromanga Basin. The Allaru Mudstone is generally 200 – 300 m thick and formed in a shallow to basinal marine setting. The Toolebuc Formation is a widespread cocquinite and underlying oil shale, varying between 6 to 45 m thick basin wide. The unit presents as a vanadium enriched 6 m cocquinite with an average 12 m thick underlying vanadium enriched calcareous oil shale unit within the tenement area. The structural geology within the tenement is benign, with a gentle anticlinal structure on both an east west and north south axis, known as the Saint Elmo Anticline (Resolve 2018).

The vanadium occurs within the unit as V2O5 and is found within organic compounds (kerogen and vanadyl porphyrins), within clays and within pyrites (within the fresh portion of the unit) and associated goethite within the oxidised units (Resolve 2018). In the oxidised rocks, vanadium within the organic compounds is unbound, which typically enhances metalliferous recovery and mining / beneficiation properties of the ore (Resolve 2018).

The V2O5 enriched oxidised units of the Toolebuc Formation show that the resource endowment is widespread and has excellent continuity within the exploration tenement. A broad, low amplitude, north-south trending anticline has resulted in the target formation being exposed and weathered over a 15 km by 5 km region, with strip ratios varying from near 0/1 to 4/1.

Commodity Production

Operational production is scalable and based on market demand, with an initial target of 5,000-10,000 tonnes per annum (tpa) and a maximum tonnage of 20,000 tpa V2O5 product over at least a 30 year mine life. However, it is noted that the Project is not anticipated to operate at this level for the entire life of the mine.

It should be noted that the maximum bank cubic meters (BCM) of material volumes to be extracted over the life of the mine have been calculated based on a 20,000 tpa output. In reality, the volume of material excavated will be less, depending on market demand.
