A$28.93 million cash and Q1 2027 Penouta study target

Penouta ownership is now complete

Energy Transition Minerals Ltd (ASX:ETM) has moved its Penouta project from acquisition into restart preparation, completing the purchase of the tin, tantalum and niobium mine and processing facility in Galicia during the September quarter. The assets and associated permits were transferred to wholly owned subsidiary ETM Spain on 20 July, while restoration guarantees of approximately €2.45 million were lodged with the Xunta de Galicia.

The transfer gives ETM control of both the Section B resource exploitation authorisation and the Section C exploitation concession. That is not the same as having a clear operating runway: the Section C concession remains suspended following a court ruling against the previous holder, with appeals before Spain’s Supreme Court still pending. The company is therefore preparing a fresh concession application as an alternative route to restarting the mine.

New concession application tied to Spanish appeals

ETM Spain is assembling an updated mining project and restoration plan, environmental and social impact assessment, Natura 2000 assessment and socio-economic impact study. The supplementary package is expected to be lodged after the relevant Supreme Court process concludes, leaving the timing of a central permitting step outside the company’s control.

The technical work is advancing in parallel. Current mine planning is underpinned by the Mineral Resource Estimate released on 4 May, following the May resource update, while ETM and consultant Altris are testing processing routes aimed at improving historical tin and tantalum recoveries. Independent reviews of tailings design and groundwater conditions are also under way, alongside environmental monitoring and work on a community investment framework.

Studies set up Q1 2027 feasibility milestone

“Location of the Penouta Tin-Tantalum-Niobium Mine”

Those workstreams are intended to support both a Scoping Study and a Pre-Feasibility Study for Penouta. ETM is targeting release of the Pre-Feasibility Study in the first quarter of 2027, although the filing does not provide a restart date, development cost, production estimate or financing plan. The study should give investors a more concrete test of whether the acquired plant and resource can support a commercially viable restart.

Cash provides time but project spending is rising

ETM finished September with A$28.934 million in cash and cash equivalents, down from A$41.672 million at the end of June. The quarter recorded A$1.792 million of operating cash outflow and A$10.535 million of investing outflow, including A$10.729 million for property, plant and equipment and A$1.654 million for exploration and evaluation. The company reported no financing inflow during the quarter.

On the Appendix 5B calculation, cash and unused facilities provide an estimated 8.4 quarters of funding at relevant outgoings of A$3.446 million for the quarter. That is a rate-based estimate rather than a project funding commitment, and the filing does not quantify the capital required to restart Penouta. The next financial picture will therefore matter alongside the technical studies, particularly if development spending accelerates.

Greenland litigation remains a long-dated second thread

ETM’s Kvanefjeld dispute also moved through a procedural stage during the quarter. The High Court of Greenland ruled on the proper defendants to Greenland Minerals’ claims against the Government of Greenland and its agencies, with substantive defences due by 27 October 2026. An oral hearing could be scheduled as early as the northern autumn of 2027 or the first half of 2028.

The related arbitration remains stayed pending the court proceedings, while parallel Danish litigation is paused. For now, Penouta supplies the operational development timetable; Kvanefjeld remains a legal process with a potentially lengthy path before any substantive resolution.
