ASX Announcement

UPDATE ON MUSGRAVE ALCURRA – TIEYON PROJECT

Woomera Mining Limited (ASX:WML, Woomera) advises that OZ Exploration Pty Ltd ( OZE ) has indicated it has decided to bring its participation in the Musgrave Alcurra – Tieyon Project ( Musgrave Project ) under the Heads of Agreement dated 11 September 2017, to an early close. The outcome of this decision would bring the Musgrave Project back to 100% control for Woomera.

OZE has requested a meeting to discuss the details for the ending of its participation in the Project, and Woomera will inform shareholders of the outcome of those discussions. While disappointing that the Heads of Agreement will not proceed with OZE, the Woomera board and management are confident that the Musgrave Project, under 100% control by the Company, remains a valuable and highly prospective asset. Woomera maintains the means and determination to press forward with exploration plans on selected targets within the Musgrave Project that have been identified by early stage exploration so far conducted under the Heads of Agreement.

Woomera remains prepared and able to proceed with the completion of the suspended drilling program (ASX: WML 27 November 2018), as soon as possible after the replacement exploration licences ( ELs ) referred to in the Company's announcement of 13 February 2019, are granted.

In this regard, Woomera notes that formal notice of the intention to make those grants was published by the SA Department of Energy and Mining ( DEM ) in The Advertiser newspaper on 14 March 2019.

Results from exploration on the Musgrave tenements to date have delivered encouraging indications to the Company that will be followed up once the replacement ELs are formally granted to Woomera. DEM has advised that the replacement ELs will be granted to Woomera once progressed through standard procedures.

Woomera continues to maintain and is actively exploring across an extensive portfolio of exploration assets situated in South and Western Australia and prospective for Copper, Lithium, Gold, Uranium, Iron Ore, Nickel and Cobalt in regions such as Mt Cattlin, the Musgraves, Pilgangoora and the Gawler Craton.

Woomera's Managing Director Gerard Anderson stated:

"We have welcomed OZE's participation in the initial stages of our exploration program for the Musgrave Alcurra – Tieyon Project and although disappointed that OZE has decided to end its participation at this juncture, we look forward to the opportunity to complete the planned drilling program, as the sole participant, upon the grant of the ELs."

“Results to date indicate to us that we do have multiple targets and a significant project here to be further exploited. We have the capacity and ability to move quickly into further exploration programs on

the Musgrave Project and we intend to do so. We will update shareholders on our forward plan as soon as possible.”
