Name of the Project
Wiluna Stage 1 sulphide project.

Location
The Yilgarn Crayton, in the Northern goldfields of Western Australia.

Project Owner/s
ASX-listed Wiluna Mining.

Project Description
The project involves the staged development of the sulphide operation from its current production of an estimated 62 000 oz/y from mining free milling ore through the current 2.1-million-tonne-a-year carbon-in-leach (CIL) processing facility, to initially produce between 100 000 oz/y and 120 000 oz/y of gold and gold in concentrate.

This transition will be realised using the current, recently refurbished crushing circuit, as well as the previously expanded mill circuit and a new 750 000 t/y concentrator.

Wiluna is further planning to increase production by at least doubling the mining rate, and increasing production by the concentrator to an estimated 250 000 oz/y of gold by the end of 2023 or early 2024.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
Not stated.

Capital Expenditure
The estimated cost of the project is A$81-million.

Planned Start/End Date
Wiluna Mining Corporation is targeting a full ramp-up of production of 120 000 oz/y at its Wiluna operation by the end of 2022.

Latest Developments
The Stage 1 750 000 t/y flotation plant is about 54% complete and mine development about 35% complete.

Underground operations are ramping up, with Wiluna’s focus remaining on securing short-term production and cash flow from the Golden Age orebody, and to continue the progressive rehabilitation of existing access and infrastructure to establish the initial stoping production areas for the start of concentrate production for Stage 1 of the operation.

The company has noted that the feasibly study for the Stage 2 operation, which would increase flotation plant capacity to 1.5-million tonnes a year, is progressing well.

The feasibility study is planned for completion at the end of 2021.

Key Contracts, Suppliers and Consultants
GRES (engineering, procurement and construction contractor for the Stage 1 works) and Byrnecut Australia (underground development and production mining services).
