A junior gold explorer is turning to third-party capital to fight what it calls the expropriation of a multi-million-ounce deposit.

According to a press release on ACCESS Newswire, ASX- and TSX-listed Sarama Resources has drawn down a four-year, US $4.4 million non-recourse facility from specialist funder Locke Capital II LLC. The proceeds will pay Boies Schiller Flexner’s fees and expert costs in Sarama’s arbitration against Burkina Faso at the International Centre for Settlement of Investment Disputes (ICSID).

Sarama alleges the government retroactively revoked its Tankoro 2 exploration permit in 2023, halting development of the flagship Sanutura project. An arbitral tribunal chaired by Prof. Albert Jan van den Berg held its first procedural hearing on 25 July; Sarama’s memorial is due 31 October, and the company is seeking no less than US $120 million in damages.

Under the Litigation Funding Agreement, Locke’s recourse is limited to arbitration proceeds and the ownership chain of Sanutura; Sarama’s other assets remain ring-fenced. Repayment occurs only on a successful award or settlement, with Locke’s return calculated on a multiple-of-invested-capital basis and adjusted for timing.

The deal underscores the continued appetite of specialist funders for investor-state claims, particularly in the mining sector where treaty protections offer a clear legal framework and potential nine-figure payouts.

International plaintiffs’ firm Pogust Goodhead has opened a fresh front in the marathon litigation over the 2015 Fundão dam collapse, dispatching a pre-action letter that accuses BHP, Vale and their joint-venture Samarco of orchestrating an unlawful plot to sabotage the English proceedings.

Acting through U.S. counsel Orrick, the firm says the miners induced claimants to sign cut-price settlements in Brazil, interfered with existing retainers and weaponised redress programmes run by the Renova Foundation to starve the London group action of participants. Pogust Goodhead pegs its damages at more than £1.3 billion—roughly the fees and uplifts it stands to lose if the 620,000-strong claimant cohort is picked off piecemeal.

An article in Reuters says the firm will argue three causes of action—unlawful means conspiracy, inducement of breach of contract and enforcement of its equitable lien—and blames the defendants’ constitutional challenge in Brazil (ADPF 1178) and the proposed “Repactuação” mega-settlement for the intensified pressure campaign.

The pre-action salvo lands just months after the close of a 13-week liability trial against BHP in London; judgment is due later this year, with a quantum phase already on the docket for 2026. Separately, Vale and BHP confront contempt allegations for allegedly funding satellite litigation to derail municipal claims. Should the new claim proceed, the miners could face parallel exposure not only for compensatory payouts—estimated at up to £36 billion—but also for the law firm’s lost fees and financing costs, which Pogust Goodhead says now exceed $1 billion.
