Update on Royalty of up to A$2 Million over Victoria gold projects

ECR Minerals plc (AIM: ECR), the gold exploration and development company focused on Australia, notes that Leviathan Metals Corp. has entered into an agreement to sell its Timor Gold project in Victoria, Australia to Au Gold Corp. (TSX: AUGC).  As part of this sale, ECR has consented to an assignment of the royalty interest that it holds over the Timor Gold project.

Highlights

•     ECR retains a royalty interest of up to A$2 million over the Avoca and Timor licences in Victoria

•     Royalty payments are linked to future resource estimates and gold production

•     ECR's royalty interest over the Timor Gold project licence is being assigned by Leviathan Metals Corp. to Havelock Gold, a subsidiary of Au Gold Corp.

The royalty originates from ECR's 2020 sale of certain gold projects in Victoria through which ECR's wholly owned subsidiary, ECR Minerals (Australia) Pty Ltd, is entitled to receive the following in respect of the Avoca and Timor projects:

1.    A$1 per ounce of gold or gold equivalent defined within a measured, indicated or inferred mineral resource estimate within the licences, capped at A$1,000,000; and

2.    A$1 per ounce of gold or gold equivalent produced from the licences, capped at A$1,000,000.

Aside from providing consent for the assignment of the royalty, the Company is not directly involved in the transaction. The assignment of the Timor project royalty to Havelock Gold includes appropriate warranties and indemnities to ensure the continued performance of the royalty arrangements previously agreed with Leviathan Metals Corp.  ECR's Avoca project royalty interest remains with Leviathan Metals Corp.

While ECR has no operational involvement in these licences, the Board believes the royalty represents potential future upside for ECR shareholders should exploration or development activities progress.

Nick Tulloch, Chairman of ECR Minerals, commented: "We consider that the Avoca and Timor royalty represents a potentially valuable legacy asset within ECR's portfolio which could deliver up to A$2 million to the Company.  Importantly, this royalty sits alongside our core Australian portfolio and requires no further capital investment from ECR, meaning any future payments would represent a direct financial benefit to the Company.

"With strong gold prices and renewed exploration interest in Victoria, we look forward to engaging with Havelock Gold to better understand their plans for the licence and the potential to unlock this value for our shareholders."
