ASX Announcement | 13 January 2025

Divestment of Mt Venn Project

Highlights

Orbminco Limited (ASX:OB1) signs non-binding heads of agreement with Sarama Resources Ltd (ASX:SRR) to divest 80% interest in Mt Venn Project.

Subject to completion, the consideration for the sale is as follows:

• A non-refundable exclusivity payment of $20,000 (which has been received); and

• The issue of 12,000,000 Chess Depository Instruments (“CDIs”) in Sarama to Orbminco (~3% of Sarama’s issued capital) upon completion.

Orbminco Limited, formerly Woomera Mining Limited, (ASX:OB1)(“Orbminco” or “Company”) is pleased to announce that it has signed a non-binding heads of agreement with Sarama Resources Ltd (ASX:SRR), to divest its 80% interest in the Mt Venn Project.

The divestment of Mt Venn aligns with Orbminco’s new focus on its Bronze Fox Project in the Mongolian South Gobi Copper Belt.

Orbminco’s Chair Ian Gordon commented: “The divestment of Mt Venn, when completed, will be a win – win for both businesses, with Sarama able to complement their Cosmos Project with another quality asset in the region and Orbminco retaining continued leverage to Mt Venn, via its shareholding in Sarama.”

Transaction Summary

As part of the terms of the divestment, Orbminco has granted Sarama a right of exclusivity on and from the date of execution of the HoA and ending after a period of 4-months or the date of execution of a binding agreement in respect of the Transaction, whichever is earlier. In return for the grant of exclusivity, Sarama has agreed to make a non-refundable cash payment of A$20,000 to Orbminco.

During this time, Sarama has also agreed to make payments on behalf of Orbminco for annual exploration licence government rental fees totalling approximately A$39,900 to ensure continuity of tenure for two of the exploration licences the subject of the Transaction.
