Latest Cost Estimation News

EcoGraf’s preliminary review has identified potential to lift Epanko Stage 1 production from 73,000 to 87,600 tonnes per annum, while reducing first-10-year C1 costs by 5.8%. The higher-output case remains subject to further engineering, financing work and a Final Investment Decision.

Comet Ridge now controls the entire Mahalo Gas Hub after completing its Santos buyout, but the annual report flags a material uncertainty over funding and a potential $28.7 million CleanCo settlement. The company is targeting a final investment decision while remaining pre-production and reliant on further finance.

Brightstar Resources says laboratory testwork across deposits representing about 80% of its Sandstone resource supports a conventional gravity and carbon-in-leach processing route, with average recoveries around 94%. The results provide the processing basis for the project’s pre-feasibility study, although Bull Oak and further variability testing remain outstanding.

Galan Lithium says first lithium chloride concentrate sales from its Hombre Muerto West operation remain on track for the fourth quarter of 2026, while plant performance improves and expansion earthworks begin. The company has also reported at least 98% sulphate rejection from its nanofiltration plant across more than three months of data.

Galilee Energy will begin sidetracking the Zydeco-1 well on 28 September to test five shallow oil zones in Louisiana. The A$3.5 million program is funded, but any move into production still depends on drilling, evaluation and flow-test results.

McLaren Minerals has moved its flagship McLaren Titanium Project into bankable feasibility, backed by a 529 million tonne resource and a 663-hole drilling campaign. But the pre-revenue explorer remains reliant on further funding, with the Barossa acquisition still conditional and 118.4 million options issued after year-end.

Anax Metals has moved its Whim Creek copper-zinc project closer to a targeted investment decision, backed by strong feasibility economics and new drilling. But the annual report makes clear that development still depends on securing further funding, with the auditor warning of a material uncertainty over going concern.

Jade Gas will use targeted 2D and 3D seismic to test whether its established coal-measure gas system extends into deeper CBM, shale gas and tight sandstone horizons in Mongolia. The exploration could expand TTCBM’s longer-term potential, but the company says commercialising existing resources remains the immediate priority.

MyState delivered a sharp rise in FY26 profit as Auswide integration produced $11.8 million in run-rate synergies, while the group lifted its full-year dividend to 24.5 cents per share. The next test is turning early integration gains into a larger payoff without losing control of technology costs and credit risk.

Caravel Minerals has delayed the Caravel Copper Project’s Definitive Feasibility Study from September to the fourth quarter of 2026. The extra time will fund further metallurgical testing, groundwater modelling, environmental updates and a detailed review of the process plant capital estimate.

Tesoro Gold has established a maiden 1.28 million-ounce JORC Ore Reserve at Ternera in Chile, entirely within a single open pit. The reserve gives the El Zorro project a 13-plus-year production base, but the next test is funding and permitting a development still at PFS stage.

Western Gold Resources has sharply expanded the proposed Gold Duke mine, lifting its production target by 62% and forecasting A$72.9 million in operating surplus. The preliminary study is stronger on paper, but still depends on funding and the restart of toll treatment at Wiluna.
