Independence Group NL (ASX: IGO) is a leading ASX-listed exploration and mining company with a strategic focus on high quality assets of scale and longevity, and an evolving strategy to align the business to the structural shift to energy storage. IGO’s Nova Operation is located in the Fraser Range, approximately 160km east-northeast of Norseman, 360km southeast of Kalgoorlie and 380km from the Port of Esperance in Western Australia.

Infrastructure Design Construct Commission

Primero has been retained by Independence Group’s Nova operation since 2017 rendering various Sustaining Capital, Shutdown and Plant Maintenance projects.

Heavy Vehicle Washbay

Primero was engaged to provide a turnkey design and construction solution to upgrade Nova’s existing non-functional Washbay. IGO was struggling with environmental non-compliance and heightened plant maintenance costs due to the extremely poor water quality in their underground mine. Care was requested to ensure minimal disruption to existing Washbay services as possible.

Highlights of the scope of work include:

Underground Refuelling Infrastructure

A design and construction solution was requested by IGO Nova for a fully DMP and Australian Standard compliant underground fuel bay. This was the first underground project completed by Primero, and received exceptional feedback from site personnel that the facility was the most fit-for-purpose, well set out and well-constructed underground fuel bay that many of them had seen. Mining delays impacting production were now mitigated as boggers and jumbos no longer needed to return to the surface for refuelling.

Highlights of the scope of work include:

Contractors Workshop

A cost-effective design and construct solution was requested by IGO Nova to house their ROM contractor Cross Verwijmeren. The workshop requirements were to be suitable for servicing CAT excavators, loaders and remaining fleet being operated over a constant 24hr roster.

Highlights of the scope of work include:

  • Steel fibre slab with non-slip surface treatment.
  • Drive-in catchment sump alongside slab to catch runoff from washing down slab.
  • Self-contained administration / crib room office connected to site comms.
  • Containerised Dome Shelter – 20m wide by 8.1m high.
  • Potable Water & Plant Air Supply within workshop.
  • Suitable lighting for 24hour servicing requirements.

MAK Reverse Osmosis Plant

IGO requested a site team to construct a new 1MEG Reverse Osmosis Plant over a duration of 2 weeks. The plant consisted of two 0.5M units, a bank of lamella clarifiers and full chemical dosing systems. Existing RO plants were causing significant plant downtime due to lack of front-end water treatment and age.

Highlights of the scope of work include:

I want to commend and thank the Primero work group that were at Nova over the last two weeks for their hard work and dedication to constructing the 750kL/day MAK Water Treatment Plant; the two photos below show the extent of the works in such a short timeframe. In two weeks the crew landed all the equipment (2 x 40ft SWRO containers, 4 x Multimedia Filters, Flocculant Dosing Skid, Oxidation Skid, 3 individual pump skids and 5 x 50kL Tanks), connected all pipework (buried or run in overhead pipe-trace where possible), installed the distribution board, ran all cables, and terminated all power and controls into the cabinets. As impressive as all this is, more so is that they executed close to 2,000-man hours without an incident. Their commitment to safety was noted.
