Production Start...
Mine Life7 years (as of Jan 1, 2022)
Focus Minerals plans to resume processing operations at the Coolgardie gold project in 2023. Company suspended production in Coolgardie in 2013.

A new Life-of-Mine plan for the resumption is aiming to produce 402,000 ounces of gold produced over a seven-year period, with a pre-commencement Capex of $51.8 million.

A $39.7 million EPC (engineering, procurement and construction) contract for refurbishment of the project’s Three Mile Hill plant has been awarded to MACA Interquip, with its commissioning scheduled for mid-2023.

Deposit Type

  • Porphyry
  • Vein / narrow vein
  • Breccia pipe / Stockwork


Summary:

Greenfields deposit
The Greenfields deposit is located within the Greenfield dolerite sill within the Coolgardie Greenstone Belt.

There are three rock types present in the pit; dolerite (southwall), felsic volcaniclastics (footwall to mineralisation) andultramafics(North Wall). The mineralisation at Greenfields forms a conjugate set of steep and moderate dipping lodes.

Mineralisation is hosted by a quartz vein stockwork that exploits a conjugate set of brittle-ductile fractures. Bucky quartz veins have accessory pyrrhotite and arsenopyrite sulphides and sometimes visible gold is observed.Veins display crack seal textures and are commonly weakly wall rock laminated.

The wall rock to the veins is commonly bleached over 0.2-0-.4m intervals.

Brilliant South deposit
The deposit lies on the western margin of the Archaean Norseman–Menzies Greenstone Belt. Host rocks at Brilliant are a sequence of Archaean Basalts and Ultramafics, which have been intruded by a suite of porphyry dykes (also described as granodiorites). The porphyries host the bulk of the mineralisation, occurring in two orientations:

1. Steeply dipping (70 -80°) with an average width of 3 to 4m(Historically conventional model used for this resource estimate),
2. Shallow east dipping (20 -40°) with average widths of up to 2-4m(not modelled at this time).

Mineralisation consists of a stock work of quartz / sulphide micro-veining and albi ........


Mining Methods

  • Truck & Shovel / Loader
  • Open stoping
  • Cemented backfill


Summary:

The Brilliant deposit would be mined by open-cut and underground via decline and stoping.

The PFS assessed a range of mining methods and proposed the Quarry Reef at Bonnie Vale being underground mined from a decline access using open stoping with cemented rock fill.

The 2020 PFS schedules two stages of open pit mining at Greenfields open pit. The staged approach delivers faster ramp up of ore production in the initial starter pit to maximise cash flow and minimise debt draw down. The follow up second stage of mining cuts back the stage 1 pit to final design minimise debt draw down. The follow-up second stage of mining cuts back the Stage 1 pit to final design. The PFS schedule for mining of Greenfields starts in Month 3 and concludes in Month 33. It is anticipated the final Greenfields open pit will be converted on completion to a tailings storage facility, pending further groundwater studies.

An existing open pit exists at Greenfields, mining would continue by cut-back and open cut extraction.
