About Mining in Western Australia

Western Australia is the world's largest mining jurisdiction by output value, producing more than 20% of global iron ore and significant proportions of global gold, lithium, and nickel. The Yilgarn Craton hosts some of the world's richest goldfields, including the Kalgoorlie-Boulder Super Pit, and the Pilbara region is the backbone of global iron ore supply.

Key minerals: gold, iron ore, lithium, nickel, copper, rare earth elements. Notable deposits: Super Pit (Kalgoorlie), Greenbushes Lithium, Nova-Bollinger Nickel, Pilbara Iron Ore. Mining districts: Kalgoorlie-Boulder Goldfields, Pilbara, Murchison, Goldfields-Esperance.

The Department of Energy, Mines, Industry Regulation and Safety (DEMIRS) administers mineral rights in Western Australia. Claim data is accessible through MyMinesOnline.

Getting Mining Data for Western Australia

Portal	Formats	Notes
MyMinesOnline	Shapefile, GeoJSON, KML	Western Australia's MyMinesOnline portal allows direct GeoJSON export of tenement boundaries — this is the fastest path to Exploration Maps with no coordinate conversion needed. Tenements use GDA2020 (essentially WGS84-compatible for mapping purposes).

How to Create a Drill Results Map for Western Australia

For a full step-by-step guide to drill results maps, see How to Make a Drill Results Map.

Import your drill collar CSV (columns: hole ID, latitude, longitude, depth, assay)
Assign the Drillholes layer role
Import the property claims boundary as GeoJSON
Add callout labels to key holes showing hole ID and best intercept
Use Badge Label type to highlight the highest-grade holes
Configure the title with program name and date
Set the Landscape 16:9 ratio for news release figures
Export as PNG at 2× for email and PDF for the news release attachment

Labelling a drillhole with its best intercept in Exploration Maps.

Tip for Western Australia: WA tenement maps typically show multiple tenure types (Exploration Licence, Mining Licence, Prospecting Licence) — use separate GeoJSON layers with distinct colors per tenure type to show the exploration-to-production progression that JORC Code reports require to be clearly distinguished.
