504.9Mt reported coal resource follows Arcadia acquisition completion

Arcadia takes Yari past 500Mt of reported resources

Yari Resources Limited (ASX:YAR) has more than doubled its reported Queensland coal inventory to 504.9 million tonnes after completing the Arcadia Coal Project acquisition on 20 October. The headline figure is substantial, but it is not a new unified resource estimate: it combines separately reported JORC resources from Arcadia and Rolleston South.

Arcadia contributes 282.0Mt, including 164.0Mt of Indicated Resources and 118.0Mt Inferred, while Rolleston South contributes 222.9Mt. Yari’s total Indicated inventory therefore rises from 33.7Mt to 197.7Mt. On the company’s calculations, resource tonnes per share increased 28.8% to 0.342 despite the issue of completion shares, while Indicated tonnes per share rose 233.7% to 0.134.

Arcadia’s coal quality offers three possible product routes

The project’s attraction is not limited to tonnage. A review of historical data from 44 bore cores and 1,472 samples identified potential for semi-soft coking, pulverised coal injection and high-energy thermal coal products, with average in-situ ash of approximately 10%.

That optionality remains preliminary. Yari and McMahon Resources still need to establish product proportions, yields, specifications and beneficiation requirements. The technical database may also expand through five petroleum and coal seam gas wells that were not included in the 2017 geological model, following the earlier Arcadia product pathways review of possible coking, PCI and thermal products.

Low upfront consideration comes with sizeable deferred obligations

The transaction was completed with A$50,000 in upfront cash and 147,594,744 escrowed shares. Using the A$0.0045 placement price as an illustrative reference, Yari puts those upfront components at approximately A$714,000, or about 0.25 cents per reported Arcadia resource tonne. The company stresses that this is not the acquisition’s total cost or an accounting fair-value assessment.

Future obligations include at least A$400,000 of qualifying expenditure over three years, A$1.25 million in resource and tenure milestone payments, A$20 million in production-linked cash payments, a 1.5% gross revenue royalty and a 10% entitlement to relevant future sale or transfer consideration. The deal’s earlier Arcadia acquisition deal had already been described as carrying substantial deferred obligations alongside the expanded resource base.

A$1.610 million cash balance leaves limited room for delay

Yari ended September with A$1.610 million in cash, boosted by the A$2.2 million placement completed to support the acquisition and project work. The quarter nevertheless produced a net operating cash outflow of A$789,000, while the cash flow report calculates 2.04 quarters of funding at the current level of relevant outgoings. There are no borrowings or unused finance facilities reported.

That runway matters because no substantive mining or development activity took place during the quarter. Yari is now combining drilling and coal-quality data from Arcadia and Rolleston South, refining geological models and planning targeted drilling aimed at improving resource confidence and identifying shallow coal zones.

Infrastructure and partnerships become the next test

Both projects sit within reach of the Blackwater rail system and Port of Gladstone, giving Yari a stated pathway to potential export markets. The company is also continuing discussions with strategic partners and commodity traders around joint venture and offtake options, while positioning the assets as part of a wider Rolleston district consolidation strategy.

The central question is whether the enlarged resource base can be converted into a commercially defined project before the funding clock becomes the more immediate constraint. Updated modelling, product testwork, drilling results and any partner or offtake arrangements will determine how much of Arcadia’s geological scale can become development value.
