Mount Mulgine

Tungsten Mining NL (ASX:TGN) is an Australian based resources company whose prime focus is the exploration and development of tungsten projects in Australia.

Primero was engaged by Tungsten Mining Limited (Tungsten) under an ECI arrangement to undertake detailed design and project development services to assist with the Mount Mulgine Tungsten / Molybdenum project located approximately 350km northeast of Perth.

Minerals Design Feasibility

With fast-tracked development being the primary objective of Tungsten at the time of engagement, the battery limits of Primero’s scope included maturing a scoping level engineering report to class 4 capital cost estimate and definitive feasibility study level detailed design.

Overview

Tungsten Mining has 100% of the tungsten and molybdenum rights on a contiguous group of tenements that have been the subject of significant previous exploration for tungsten and molybdenum.

The Mt Mulgine process plant comprises the following five areas:

Additionally, Tungsten purchased a secondhand mill and gravity plant and wished to relocate the Tabba Tabba plant and repurpose the equipment as far as reasonably practicable throughout the Mt Mulgine flowsheet.

Primero was responsible for defining the process flowsheet, equipment selection, condition reporting upon secondhand equipment and capital cost preparation for the engineering, procurement and construction of the tungsten and molybdenum concentrator. This work has included value engineering and optioneering to define alternative start-up options, in terms of scale (production throughput), plant configuration and cost trade off (capital versus operating).

As critical long lead items, Primero worked alongside Tomra Sorting Solutions to identify and procure two x-ray sorting solutions.
