Diamond mining company Gem expressed confidence on Tuesday that its Letšeng operation in Lesotho would be able to ramp-up to full production rapidly once the Covid-19 lockdown period was lifted and all employees and contractors were able to return to site safely. The London-listed company said in its first-quarter trading update for the three months to March 31 that among several steps taken to combat Covid-19 in the Mountain Kingdom was the provision by the company of a mobile office unit with 25 000 test kits to the Department of Health in Maseru.
