Most of the lead-zinc sulfide mine uses preferential flotation technology, “floating lead and zinc-suppressing”, which is often reasonable both technically and economically.
Historically, the mine produced approximately 700,000 tonnes of ore (calculated from the company's 3d models of the mine voids), producing over 100,000 tonnes of lead and zinc concentrate, and over 1,000,000 ounces of silver. After net smelter returns, this would have yielded revenues in excess of us$100 million at current commodity prices.

Essentially all lead and zinc mining in the ouachita region was by underground methods. Although zinc is more common, lead ore was recognized and developed first in the north arkansas district because of its use for bullets.
As lead mining declined in mineral point, zinc mining and smelting became important new industries. Zinc ore was discovered with increasing frequency near the bottoms of old lead mines. The mineral point zinc company was founded in 1882, and by 1891 it was operating the largest zinc oxide works in the united states at mineral point.
