Name of the Project
Mulga Rock uranium project.

Shire of Menzies, in Western Australia.

Project Owner/s
Deep Yellow.

Project Description
Mulga Rock consists of two mining areas over a total length of 30 km, with individual deposits ranging in length from 1 km to 8 km. The Mulga Rock East mining centre comprises the Ambassador and Princess deposits, and the Mulga Rock West mining centre comprises the Shogun and Emperor deposits.

The project currently has an expected mine life of 15 years, with yearly production estimated at 3.4-million pounds of uranium and life-of-mine production estimated at 47.1-million pounds of uranium.

Potential Job Creation

Net Present Value/Internal Rate of Return
Not stated.

Capital Expenditure
Not stated.

Planned Start/End Date
Production is expected in 2028.

Latest Developments
Deep Yellow has reported a 26% increase in the total contained uranium in the Mulga Rock East project to 71.2-million pounds and delivered a substantial uplift in the critical mineral value of the asset.

The critical minerals’ inventory, including copper, nickel, cobalt and zinc, increased by between 200% and 400%, depending on the element.

The updated mineral resource estimate at Mulga Rock East comprises 73.9-million tonnes at 605 parts per million (ppm) uranium oxide equivalent at Ambassador and 7.3-million tonnes at 425 ppm uranium equivalent at Princess.

In order to re-rate and grow the Mulga Rock project, Deep Yellow had to undertake a considerable amount of preparatory drilling for essential metallurgical testwork to establish the leaching characteristics of the critical minerals and prepare an updated mineral resource estimate focusing on the uranium and non-uranium (critical minerals) components associated with the deposits.

The company will now progress to a definitive feasibility study (DFS).

Key Contracts, Suppliers and Consultants
GR Engineering Services (updated DFS), including Piacentini & Son (earthmoving); and Thinking Human Resources and OfficeSolutions IT (information technology and communications).
