Name of the Project
Warrawoona gold project.

Location
Pilbara, Western Australia.

Project Owner/s
Calidus Resources.

Project Description
The Warrawoona project is a high-margin gold operation, with average gold production estimated at 90 000 oz/y over an initial eight-year mine life.

The project has a global resource of 43.7-million tonnes grading 1.06 g/t gold for 1.5-million ounces.

The project includes a two-million-tonne-a-year conventional carbon-in-leach processing circuit with a single-stage crushing and semiautogenous grinding mill.

Calidus’ acquisition of the high-grade Blue Spec mine provides immediate opportunity to expand production and free cash flow at the project. The definitive feasibility study and integration plan are being undertaken in parallel with the construction of Warrawoona.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has a pretax net present value, at an 8% discount rate, of A$408-million and an internal rate of return of 81%, with a payback of 13 months.

Capital Expenditure
The project has a capital cost of $120-million, including contingency and preproduction mining costs.

Planned Start/End Date
The project is expected to pour first gold in the first half of 2022.

Latest Developments
Calidus Resources has poured first gold from its Warrawoona gold project, marking the successful completion of commissioning of the full processing circuit, with 33 kg of gold now having been poured.

The process plant has achieved milling rates of 2.2-million tonnes a year, and a full ramp-up to 2.4-million tonnes a year is expected to be completed this quarter.

“Over the remainder of the quarter, we will focus on our operational ramp-up and other site activities, including our active exploration programmes that have taken place during the course of development,” Calidus MD Dave Reeves has said.
