BHP's uranium production has been falling over the past year, it has only one mine in South Australia, Olympic Dam.
Olympic Dam is however the fourth largest copper deposit and the largest known single deposit of uranium in the world. Copper is the largest contributor to total revenue at that mine, accounting for approximately 70%, with 25% from uranium, and approx 5% from silver and gold.
However, in terms of total BHP revenue, uranium is an insignificant financial contributor, something like no more than 1%.
