What is the biggest Zinc mine in Australia?

Question

Is it Broken Hill mine or the Century one in QLD?

Or another one?

Answer 1

In 1883, Charles Rasp discovered the rich and extensive Broken Hill lead-zinc-silver deposit when he found some dark, heavy rocks which he thought may contain tin. Subsequent assays of these rocks proved that he had located rich oxidized (weathered) silver and lead minerals. Broken Hill provided the basis for Australia's current major zinc mining industry. Ore is still being mined at Broken Hill which has been the largest producer of lead-zinc-silver in Australia.

The rich lodes at Mt Isa were not discovered until 1923 and were developed despite the remote location and harsh environment. The nearby, rich Hilton deposit was discovered in the late 1940s but not developed until the mid-1980s. Production at Mt Isa continues and it has been the second biggest zinc producer in Australia. In the Mt Isa region, there are large mines at the George Fisher, Cannington and Century deposits, while the Dugald River and Lady Loretta deposits are yet to be developed. In the Northern Territory, the large McArthur River deposit is a major producer.
