Caledonia Mining Corporation (LON:CMCL, NYSE:CMCL) said on Friday it had potentially secured the future of its Blanket mine in Zimbabwe for the next 20 years by opting to extend the central shaft on site to greater depths.
It comes on the back of the recent resource upgrade, which underlined the potential volumes and grade at depth.
Total measured and indicated gold ounces now amount to 714,000 ounces compared to 671,000 ounces at the end of 2016, the company said last week.
The central shaft is currently under construction, and will now be extended by a further 250 metres to a depth of 1,330 metres and fully commissioned by the end of the first quarter of 2020, the mining group said.
"The creation of an additional two levels will also increase the mining flexibility and further de-risk the target production of 80,000 ounces per annum from 2021," the firm said.
It was one of a host of mining stories that featured this week on the Proactive site.
