Zvinakis Mining Company paid $200,000 for the rights to mine lead in southeast Missouri. The cost to drill and erect a mine shaft was $2,400,000, and equipment to process the lead ore before shipment to the smelter was $1,800,000. The mine is expected to yield 2,000,000 tons of ore during the five years it is expected to be operating. The equipment has an estimated residual value of $150,000 when mining is concluded. The mine started operations on April 30, 2013. In 2013, 300,000 tons of ore were extracted, and in 2014, 700,000 tons were mined.
