Theta Gold Mines (ASX:TGM) executed a non-binding term sheet with Nebari Partners, a US-based investment manager, or its affiliates for a proposed senior secured loan facility of up to $80 million to support the development and commissioning of its gold mining projects in South Africa, according to a Tuesday Australian bourse filing.

The first tranche of $45 million is expected to be available in early 2026, the filing said. Three months after closing, the company may draw down the second tranche of up to $35 million.

The parties will proceed to the completion of an extensive due diligence, including legal and technical reviews, to allow approvals by Nebari's investment committee.
