Savannah Resources secures $40m as Barroso lithium project moves toward construction

Savannah Resources PLC (AIM: SAV), a London-listed mineral development company advancing the Barroso Lithium Project in northern Portugal, has completed a £30.09 million, or approximately US$40.23 million, equity financing through an institutional placing, subscription and retail offer. The company issued 547.1 million new shares at 5.5p apiece, while major shareholders AMG Lithium B.V. and Telmory LDA participated to maintain their positions. Combined with existing resources, Savannah said the financing leaves it with more than US$53 million as it prepares Barroso for construction.

The financing arrives after Savannah completed a Phase 1 definitive feasibility study that estimated initial capital expenditure of US$417 million including contingencies, or US$377 million before contingencies. After accounting for the Portuguese State grant, the DFS put initial capital expenditure excluding contingencies at US$283 million, underlining why the September raise materially strengthens Savannah but does not complete the entire project-financing requirement.

How much dilution does Savannah’s new 547 million-share issue create?

The new shares represent roughly 21% of Savannah’s enlarged share capital, meaning investors who did not participate in the fundraising have experienced meaningful dilution to their percentage ownership. Put another way, the 547.1 million new shares equal roughly 27% of the pre-financing share count, making this one of the more consequential capital raises in Savannah’s recent history. The 5.5p issue price was below the approximately 6p level at which Savannah had traded before the funding process began, although the stock closed September 25 around 5.82p after trading resumed.

That dilution needs to be judged against what Savannah has bought with the capital. A pre-production miner that cannot fund engineering, permitting, land access and early construction preparation risks destroying value through delay just as surely as it can through share issuance. Savannah now has enough corporate liquidity to progress several important pre-construction workstreams while negotiating the much larger debt and strategic financing package required for Barroso.

The participation of AMG Lithium and Telmory is also relevant because it prevents those cornerstone shareholders from being automatically diluted by the raise. Their involvement does not guarantee future project financing, but it demonstrates continuing financial support from major holders at the current stage of project development.

Why does Savannah still need project finance despite having more than $53 million?

Barroso’s scale makes the answer straightforward. The 2026 DFS envisages average production of approximately 183,000 tonnes a year of 5.5% lithium oxide spodumene concentrate over an initial 14-year mine life, with an unlevered post-tax net present value of US$913 million and post-tax internal rate of return of 43.2%. The same study estimates US$417 million of initial capital including contingencies, which is several times larger than Savannah’s enlarged corporate cash balance.

The Portuguese Government grant materially reduces that burden. Savannah has been awarded up to €110 million of non-repayable State support, including €82.25 million allocated toward initial development capital expenditure. Even after that assistance, however, Savannah needs debt financing, further strategic capital or another source of project funding before Barroso can move through full construction without placing excessive pressure on the listed company’s balance sheet.

Management has already been progressing discussions with prospective lenders and potential offtake partners. Savannah said earlier in September that it was working with a shortlist of financing counterparties and targeting conditional project-finance proposals by the end of 2026, with a final investment decision expected in early 2027 if the remaining workstreams progress to plan.

Is Barroso economically strong enough to support the remaining funding requirement?

The DFS provides a relatively strong starting point. It estimates average life-of-mine C1 operating costs of US$473 per tonne of concentrate and all-in sustaining costs of US$646 per tonne, compared with an assumed average concentrate price of US$1,788 per tonne. Total life-of-mine EBITDA was estimated at approximately US$3.23 billion and post-tax free cash flow at US$1.94 billion.

Those projections explain why Savannah can reasonably pursue a substantial project-debt component rather than attempting to fund the mine entirely with shareholder equity. Lenders will nevertheless apply their own assumptions to lithium prices, construction costs, operating performance, environmental commitments and completion risk rather than simply accepting the company’s DFS valuation.

Lithium pricing remains one of the largest external variables. The project’s calculated post-tax break-even concentrate price was US$747 per tonne, which provides some theoretical downside protection against the DFS price assumption, but commodity cycles can be long and volatile. A financing package that remains serviceable under conservative lithium-price scenarios would be substantially more valuable to Savannah shareholders than simply maximising headline leverage.

What does the 5.82p share price say after the funding announcement?

Savannah finished September 25 around 5.82p, above the 5.5p financing price but below recent September levels around 6p. That is a relatively measured response to an equity issue representing more than one-fifth of the enlarged company, suggesting investors are balancing dilution against the substantial reduction in near-term funding risk.

The fundraising also removed uncertainty created by the temporary trading suspension associated with the Capital Access Window. Trading resumed on September 25 once the financing process closed, giving the market the first opportunity to price the enlarged share count against the stronger cash position.

For Savannah shareholders, the next major valuation event is unlikely to be another ordinary exploration update. Conditional project finance, a second offtake arrangement and the eventual final investment decision will determine whether Barroso moves from a well-funded development story into construction. The US$40 million financing buys Savannah time and negotiating strength, but the terms of the remaining capital will determine how much of Barroso’s US$913 million estimated project value ultimately belongs to each existing share.
