Name of the Project
Tampia gold project.

Location
The project is located in the wheatbelt of Western Australia.

Client
Explaurum.

Project Description
Tampia has a mineral reserve of 7.2-million tonnes grading 2.09 g/t and an updated mineral resource of 11.7-million tonnes grading 1.79 g/t gold. The project comprises a single openpit, within close proximity to the proposed plant site.

The mine plan is based on an optimised mining schedule, mining weathered (surface) and shallow fresh material first.

Mining activities will be undertaken by Explaurum using equipment on a dry hire con-tract basis, whereby all equipment necessary to meet the planned mining schedule is provided on an hourly rate and guaranteed availability basis, with management and staffing being the responsibility of the principal.

The proposed process plant is based on:

∞ primary crushing (direct truck dumping of ore in the jaw crusher with front-end loader backup);

∞ a single-stage semiautogenous milling comminution circuit;

∞ a gravity concentration and intensive leach reactor;

∞ flotation of sulphides (3% to 5% mass pull, including löllingite);

∞ ultrafine grinding and enhanced leaching of the flotation concentrate;

∞ a carbon-in-leach circuit; and

∞ elution electrowinning and smelting of gold doré.

The nominal throughput capacity is estimated at 1.5-million tonnes a year.

The project has an initial mine life of 5.3 years.

Potential Job Creation
None stated.

Net Present Value/Internal Rate of Return
The project has a pretax net present value, at an 8% discount rate, of A$125-million and an internal rate of return of 47%, with a payback of 18 months.

Value
Preproduction capital costs are estimated at A$119-million, including a A$10.8-million contingency.

Duration
Not stated.

Latest Developments
A bankable feasibility study is expected to be completed in October 2018, with construction, subject to development finance, regulatory and board approvals, expected to start in December 2018.
