VIDEO: Coeur Mining to grow silver production with $1.7bn acquisition of Silvercrest
Adding Las Chipas makes Coeur a top silver producer in North America, with 21 million ounces of silver and 432,000 ounces of gold annually.
Kootenay Silver (TSXV: KTN) has signed a contract with Tlasa Obras Mineras to rehabilitate the historic underground workings on the F vein at the Columba silver project in Chihuahua, Mexico.
Clearing and timbering an adit is already underway to reach the main shaft and a secondary inclined shaft so that dewatering can begin. Once access to the F vein is secured, detailed mapping and sampling will begin so that accurate modelling and resource work can begin, the company said.
Kootenay said there are no historic data available on the F vein and no way of knowing the condition of the workings or whether there were any collapses. The work is expected to take about four months.
Other veins at Columba are being drilled as part of a 5,000-metre program.
