Blue Bar Gold Mine

The Blue Bar gold deposit is situated within the Marble Bar district, East Pilbara, Western Australia — one of the most geologically ancient and thermally extreme terrains on Earth. Positioned within the Pilbara Craton's Archaean greenstone belt, the site endures ambient temperatures exceeding 50°C in summer. Extreme aridity defines operational risk: annual rainfall averages below 300 mm, making water supply infrastructure — including bore fields, storage tanks, and recycled process water circuits — a non-negotiable operational prerequisite for any B2B contractor or vendor engaging on-site.

Calidus Resources Limited (ASX: CAI) executed a Binding Profit Share Agreement with Haoma Mining NL, unlocking development approval for Blue Bar. The project operates under a structured B2B procurement model typical of junior ASX-listed gold developers. Operational continuity depends on:

• FIFO rotational rosters (typically 8/6 or 14/7 swing cycles)
• Fly-in access via Port Hedland Airport (PHE), ~200 km southwest
• Contracted earthworks, drilling, and processing service providers
• Local Indigenous Land Use Agreement (ILUA) compliance obligations

The Blue Bar deposit targets open pit extraction methodology consistent with shallow Pilbara greenstone-hosted gold mineralisation. Material handling relies on engineered conveyor belt systems linking the pit face to the ROM (Run-of-Mine) pad and processing circuit. Key infrastructure considerations include:

• Crushing and screening plant integration
• Conveyor transfer stations rated for high-abrasion lateritic and siliceous ore
• Gravity and/or CIL (Carbon-in-Leach) gold recovery circuit
• Tailings storage facility (TSF) engineered for arid-climate evaporation rates

Operating in the Pilbara demands measurable ESG decarbonisation commitments to satisfy ASX disclosure requirements and institutional investor mandates. Blue Bar's sustainability framework is expected to incorporate:

• Solar hybrid power generation to offset diesel dependency at remote site
• Battery Energy Storage Systems (BESS) for load-shifting and grid stability
• Progressive rehabilitation and native vegetation restoration obligations
• Scope 1 & 2 emissions reporting aligned with TCFD and GRI frameworks
• Traditional Owner engagement embedded in the project's social licence strategy
