Karari Gold Mine

Karari Main And Exploration Declines is situated within the Kurnalpi greenstone belt, approximately 100 km northeast of Kalgoorlie in the Goldfields-Esperance Region of Western Australia. The terrain is characterised by flat to undulating semi-arid landscape with red ferruginous soils generating extreme fine-dust (red dirt) conditions. This environment imposes severe abrasion loads on all surface and portal-level mechanical assets, driving acute demand for high-grade filtration systems, dust suppression infrastructure, and accelerated wear-part replacement cycles across all mobile and fixed plant.

Currently classified as Operating, Karari functions as an active underground gold producer integrated into Northern Star's Carosue Dam Operations hub. The dual-decline configuration — Main Production Decline and Exploration Decline — enables simultaneous ore extraction and resource extension drilling. B2B vendors must account for:

• Continuous decline development requiring ground support consumables (mesh, bolts, shotcrete)
• High-frequency demand for underground mobile fleet servicing
• Local mechanical workshop capability to minimise unplanned downtime and avoid costly fly-in component logistics
• Integrated scheduling within Carosue Dam's multi-pit and multi-decline production calendar

Ore extracted from Karari declines feeds into the Carosue Dam processing plant, which operates a conventional CIL (Carbon-in-Leach) circuit. Key engineering demand nodes include:

• Primary grinding circuit: SAG and ball mill assemblies with high liner wear rates driven by abrasive greenstone ore
• Flotation and gravity concentration pre-treatment stages with stringent physico-chemical reagent control
• Decline ventilation systems requiring robust fan assemblies and ducting rated for fine-particulate environments
• Paste fill or cemented aggregate fill (CAF) reticulation for void management in stoped areas

Suppliers of mill liners, reagents, and ventilation equipment hold strategic positioning at this operation.

Northern Star Resources operates under a formal Reconciliation Action Plan (RAP), making Heritage compliance and Indigenous engagement non-negotiable procurement criteria in the Kurnalpi corridor. B2B priorities include:

• Mandatory Aboriginal Heritage surveys prior to any new decline or surface disturbance footprint
• Preferential procurement alignment with Wangkatha and Ngadju Country Traditional Owner enterprises
• Water management obligations under WA Department of Water and Environmental Regulation (DWER) licensing
• Carbon reporting integration within Northern Star's Scope 1 & 2 emissions reduction roadmap to 2030

Vendors offering Indigenous-partnered service models gain measurable competitive advantage in tender evaluation at this site.
