Frequently Asked Questions
Where is diamond mining located in Western Australia?
Diamond mining in WA is centred in the East Kimberley region, most notably at the Argyle Diamond Mine near Lake Argyle. The region's lamproite and kimberlite geology makes it highly prospective for diamond deposits, and several junior explorers continue to target the area.
Is the Argyle Diamond Mine still operating in WA?
No. The Argyle Diamond Mine, operated by Rio Tinto, officially closed in November 2020 after more than 37 years of production. During its operational life, Argyle produced over 865 million carats of diamonds, making it one of the most prolific diamond mines in history.
What opportunities exist for diamond exploration in Western Australia today?
Despite Argyle's closure, WA remains an active frontier for diamond exploration. Junior mining companies hold tenements across the Kimberley and other prospective regions, targeting undiscovered kimberlite and lamproite pipes. Advances in geophysical surveying and remote sensing continue to drive new exploration activity across the state.
