Lena Gold

The Lena gold mine is situated in the Day Dawn locality, Mid-West Region of Western Australia, approximately 500–550 km northeast of Perth. This remote positioning creates extended supply chain corridors via the Great Northern Highway, directly impacting lead times for consumables, reagents, and heavy equipment. The semi-arid terrain presents seasonal access constraints, demanding robust logistics planning from all B2B vendors servicing the site.

As an operating asset, Lena sustains continuous 24/7 production cycles with a critical dependency on:

• Diesel fuel supply for mobile fleet, generators, and auxiliary systems
• Grid-tied or isolated power substation infrastructure for processing plant loads
• Scheduled FIFO/DIDO rotational workforce logistics from Perth or Meekatharra
• Ongoing procurement of grinding media, explosives, and chemical reagents

Gold recovery at Lena relies on a conventional hard-rock processing circuit encompassing:

• Primary crushing and SAG/ball mill grinding circuit for ore liberation
• Gravity concentration followed by carbon-in-leach (CIL) or flotation processing
• High reagent demand: sodium cyanide, lime, and flocculants at precise physico-chemical tolerances
• Electrowinning and smelting for doré bar production

Operational compliance in Mid-West WA mandates rigorous environmental stewardship:

• Engineered tailings storage facilities (TSF) with lined embankments and leachate monitoring
• Progressive rehabilitation programs aligned with DMIRS and EPA Western Australia directives
• Water recycling circuits to minimise freshwater drawdown in arid conditions
• Dust suppression and native vegetation offset obligations under state mining approvals
