JSE-listed Union Atlantic Minerals (UAM), previously known as Miranda Minerals, will place its brownfield exploration projects on care and maintenance, with minimum staff and fieldwork to be pursued until the Covid-19 pandemic has been ameliorated and the prospects for junior mining and exploration companies, as well as global commodity prices, improve. The company confirmed on May 6 that no staff or consultants were active in the field on company projects and that, as a consequence, there was “no operational risk of Covid-19 for company staff or consultants”.
