The Goldfields: Australia's gold mining heartland

Kalgoorlie-Boulder sits 595 kilometres east of Perth in the Eastern Goldfields region of Western Australia. The city of 30,000 people exists because of gold—specifically, the discoveries of Paddy Hannan in 1893 that triggered one of the world's great gold rushes. Over 130 years later, the Goldfields remain Australia's most productive gold mining region, with major operations surrounding Kalgoorlie and extending north to Leonora, east to Kambalda, and south to Norseman.

The region's geology is dominated by the Yilgarn Craton, one of the world's great granite-greenstone terranes. Gold occurs in narrow quartz veins within sheared greenstone belts, in larger disseminated deposits, and in paleochannel placer deposits. This geological diversity means mining methods vary widely—from narrow vein underground operations to massive open-cut pits like the Super Pit. Each method demands specific survey expertise.

Kalgoorlie itself functions as the regional hub. The city has a regional airport with regular flights to Perth, a full range of mining services suppliers, and a skilled workforce with deep mining expertise. For surveyors, Kalgoorlie is the gateway to the Goldfields—a base from which to service mines across a 300-kilometre radius.

Key point: The Goldfields' combination of large-scale open-cut and narrow-vein underground operations creates diverse survey demand. A surveyor working here must be equally comfortable on a Super Pit bench and in a 2-metre-high development drive 800 metres underground.

Major gold operations and survey requirements

Kalgoorlie Consolidated Gold Mines (KCGM) — The Super Pit

The Super Pit is the iconic operation of the Australian gold industry. Measuring approximately 3.5 kilometres in length, 1.5 kilometres in width, and over 600 metres in depth, it has produced more than 21 million ounces of gold since 1989. Northern Star Resources holds a 50% interest and manages the operation.

The Super Pit's scale creates unique survey challenges:

• Pit progression and bench surveys — Fortnightly or monthly topographic survey of pit walls, benches, and floors for short-term planning and ore/waste reconciliation. The pit's depth means surveyors must work around haul truck traffic on narrow bench roads while maintaining precise control.
• Wall stability monitoring — Laser scanning and precision monitoring of high walls for geotechnical stability assessment. The depth of the pit increases wall failure consequences.
• Underground workings interface — The Super Pit overlays extensive historical underground workings. Survey data must accurately define the interface between open-cut and legacy underground voids.
• Processing plant surveys — The Fimiston processing plant (the Gidji Roaster and Fimiston Mill) requires mechanical survey for equipment maintenance, upgrade, and new installation.

Northern Star Resources — Kalgoorlie Production Centre

Beyond the Super Pit JV, Northern Star operates Kanowna Belle (underground), Kundana (underground), East Kundana (underground), and South Kalgoorlie (open-cut) in the Kalgoorlie region. The company is one of Australia's largest gold miners, with operations across WA and into North America.

Northern Star's survey requirements include:

• Underground mine surveys — Kanowna Belle and Kundana are long-life underground mines requiring statutory survey, development set-out, stope pickup, and void scanning.
• Open-cut progression — South Kalgoorlie and other open-cut satellites require regular pit and dump survey for planning and reconciliation.
• Regional exploration support — Northern Star's aggressive exploration programme across the Kalgoorlie region requires drill pad set-out, control network establishment, and terrain survey.

Evolution Mining — Mungari

Evolution Mining operates the Mungari processing plant and surrounding open-cut and underground mines approximately 20 kilometres west of Kalgoorlie. Mungari is a regionally significant operation with a centralised processing facility feeding multiple ore sources.

Evolution's survey needs include:

• Multi-mine coordination — With multiple ore sources feeding a central plant, accurate survey control across all pits and underground drives is critical for ore tracking and blend control.
• Processing plant survey — Mechanical and structural survey for the Mungari CHPO and associated infrastructure.

Other Goldfields Operators

The Kalgoorlie region hosts numerous other producers: Ramelius Resources (Mt Magnet, Edna May), Westgold Resources (Big Bell, Fortnum, Paddy's Flat), Silver Lake Resources (Mount Monger), and Red 5 (King of the Hills). Each operation generates ongoing survey demand for production, development, and compliance.

Underground gold mine surveying

Underground gold mining in the Goldfields employs several methods: long-hole open stoping, decline access with truck haulage, shaft-based operations, and narrow vein development. Each method places different demands on survey.

ISS provides underground survey services including:

• Development set-out and pickup — Survey control for decline, level, and drive development. Every metre of advance requires alignment verification, grade confirmation, and pickup for as-built records.
• Stope and void surveys — Post-extraction stope surveys using cavity monitoring systems (CMS) or laser scanning to determine actual extraction boundaries, dilution, and remnant ore for planning.
• Raise and winze set-out — Vertical and sub-vertical openings require precise set-out for drilling and blasting.
• Control network maintenance — Underground survey control networks must be extended, checked, and adjusted as development progresses. Traversing in confined, hot, and vibrating environments demands precision instrumentation and rigorous procedure.
• Shaft surveys — For shaft-hosted operations, ISS provides shaft plumbing, winding engine alignment, and shaft station set-out.

The Goldfields' underground mines are deep, hot, and geologically complex. Some operations work at depths exceeding 1,000 metres below surface, where rock temperatures approach 50 degrees Celsius. Survey equipment must perform reliably under these conditions, and surveyors must work efficiently to minimise exposure time.

Open-cut pit and dump surveys

Open-cut gold mining in the Goldfields ranges from small satellite pits feeding central mills to the Super Pit itself. Common survey requirements include:

• Pit progression pickup — Regular topographic survey of active mining areas for short-term planning, blast design, and ore/waste delineation.
• Blast pattern set-out — Precise drill pattern layout for production blasting, with post-blast pickup to assess diggability and fragmentation.
• Dump and landform management — Waste dump progression surveys ensure dumps are constructed to design profiles for stability and rehabilitation.
• Rehabilitation monitoring — Progressive rehabilitation is required under WA mining legislation. Drone and ground surveys track landform and vegetation establishment against approved completion criteria.
• Volumetric surveys — Ore stockpiles, waste dumps, and tailings storage facilities require volume measurement for inventory, compliance, and planning.

UAV/drone surveys have become the default method for open-cut progression and volumetric work in the Goldfields. A single drone flight can capture a complete pit or dump in hours, with data processing producing orthophotos, digital surface models, and volume calculations within 24 hours.

Processing plant and infrastructure surveys

Every Goldfields gold mine operates a processing plant—ranging from modest 500,000-tonne-per-annum facilities to multi-million-tonne complexes. These plants contain crushers, grinding mills, gravity circuits, leach tanks, carbon-in-pulp (CIP) circuits, electrowinning cells, and tailings handling systems.

ISS provides mechanical surveys and engineering surveys for processing infrastructure:

• Crusher alignment — Primary and secondary crushers require precise levelling and drive train alignment. Vibration from misalignment damages bearings and reduces throughput.
• Mill installation and alignment — SAG and ball mills are the largest and most critical equipment in gold plants. Girth gear alignment, pinion positioning, and foundation set-out require sub-millimetre precision.
• Tank and vessel positioning — Leach tanks, CIP tanks, and thickener assemblies require precise set-out relative to feed and discharge systems.
• Conveyor and pipeline surveys — Ore and slurry conveyors, water pipelines, and tailings delivery lines require alignment and as-built documentation.
• Tailings storage facility (TSF) surveys — TSF construction, raise design, and monitoring require precise survey for safety and compliance.

3D laser scanning is increasingly used for processing plant as-built documentation. Dense point clouds capture complex pipework and equipment arrangements that would take weeks to survey conventionally. These models support retrofit design, capacity upgrades, and digital twin development.

How ISS services the Kalgoorlie Goldfields region

Industrial Spatial Solutions services the Goldfields through direct project engagement, scheduled site visits, and FIFO mobilisation from Perth. Our approach recognises the specific challenges of working in this region:

• Kalgoorlie-based coordination — We coordinate projects through Kalgoorlie, minimising mobilisation time and cost for sites within the region.
• FIFO from Perth — For larger projects or clients preferring Perth-based coordination, we mobilise on commercial flights or charter as required.
• Underground and open-cut experience — Our surveyors have worked across the full range of Goldfields mining methods, from Super Pit bench work to narrow-vein underground development.
• Equipment for harsh conditions — Our instruments are selected and maintained for performance in heat, dust, and vibration. We carry backup equipment to site to ensure surveys are completed on schedule.
• Mine-ready data formats — Deliverables in Surpac, Vulcan, Deswik, AutoCAD, or your preferred format, in your mine grid or GDA2020 as required.

Western Australia's surveyor shortage is acute. With 151,000 resources jobs and the highest resources share of any state economy (43.6%), competition for survey professionals is intense. For Goldfields operators, securing reliable survey support means working with specialists who understand mining—not generalists who happen to own a total station.

Frequently asked questions

Does ISS have experience with narrow-vein underground gold surveys?

Yes. Several of our senior surveyors have extensive experience in narrow-vein underground gold mines across the Goldfields and elsewhere in WA. We understand the specific challenges of working in confined drives, maintaining control through limited openings, and delivering accurate stope surveys in difficult conditions.

Can ISS provide survey support for exploration programmes around Kalgoorlie?

Absolutely. The Goldfields remain highly active for gold exploration, with drilling programmes running year-round. ISS provides control network establishment, drill pad set-out, RC and diamond drill collar pickup, and terrain modelling for exploration projects. We can mobilise quickly to remote exploration camps across the region.

What is the typical turnaround for drone survey data in the Goldfields?

For standard pit progression or stockpile volumetrics, we typically deliver processed data within 24-48 hours of flight. This includes orthophotos, digital surface models, and volume calculations. For laser scanning projects, point cloud registration and delivery typically takes 2-5 days depending on complexity.

Does ISS work with junior miners and exploration companies, or only major producers?

We work with operators of all sizes. Junior miners and explorers often have tighter budgets and more urgent timelines—they cannot afford survey delays any more than major producers can. We tailor our scope and methodology to match your project requirements and budget constraints.
