The Mount Garnet Tin Project is focused on three outcropping tin bearing skarn deposits of Gillian, Pinnacles and Windermere.

Mining method will be by open cut with an average mining cost per tonne of A$24.25/t. Pit designs were based on Whittle optimisation shells generated using preliminary operating cost estimates. Mine development and operation is reflected as contractor mining. Ore will be transported to the Mt Garnet concentrator subject to final agreement with Snow Peak.

The essential elements of the process plant design include the following primary comminution and flotation stages:
- Multi-stage crushing
- Primary grinding using the existing SAG mill and ball mills with one additional ball mill added from existing grind circuit
- Reverse Silica flotation through a series of conventional flotation cells with rougher and cleaner cells with additional primary cells added

The combined high iron concentrate material containing tin will report to final filter where moisture is extracted prior to being pelletised and fed to the tin roasting circuit.

Tin fume at 68% Sn will be recovered through a gas handling system consisting of gas cooling, followed by a series of filters (Bag House) with continuous recovery of SnO2 as a solid prill for dispatch to smelters. Final gas cleaning and lime scrubbing will ensure release of clean air to the atmosphere.

Magnetite will be continuously recovered from the rotary kiln discharge where it will be cooled and conveyed to the magnetite stockpile for dispatch to port. Process water is available from water bores and an existing external water supply dam.

The process tails will be transferred to a tailings thickener to facilitate water conservation followed by deposition in a tailings storage facility. Tailings water will be reused in the process.

Various conventional flotation and flocculent chemical additives will be used in the process.
