The mine is located in the Northern Territory of Australia, about 80 kilometres south of Borroloola.

The mine operated for a period of about three years from 2000 to mid-2003, during which time it produced about 500,000 carats (100 kg) of high quality diamonds.

The Merlin mine has an unusually high proportion of gem-quality diamonds: 65% of production is gem-quality, and only 35% is classified as near-gem or industrial quality.

The known ore grade at Merlin is about 0.2 carats (40 mg) per tonne, although exploration continues under the mine's new owner.

Striker has since become North Australian Diamonds [3], a company which operated the mine for a short period in 2006.
