The Financial Post reports in its Friday edition that Barrick has purchased more than 800,000 finger-prick antibody testing kits to screen workers and the communities close to its mines. A Financial Times of London item inside the Post quotes chief executive officer Mark Bristow saying the company had invested a lot in the tests, which can be used to detect if a person's immune system has COVID-19 or has recovered from it. "We've got 300,000 kits on the way. We've got about 150,000 in the country already and another 400,000 that we have just finalized," Mr. Bristow told the FP from Johannesburg, where he is working from a home he has not lived in for 12 years. "We buy them from all over the place: South Korea, China. We've bought some from the U.K. There are also some local tests available in the Dominican Republic." Barrick is one of one of the world's biggest mining companies, with assets spread around the globe. While there are broad concerns about the accuracy of antibody tests for COVID-19 -- the U.K. government, for example, has said none of the 17.5 million kits it has ordered are good enough to be used -- Mr. Bristow said, "It's not a definitive test but it's good enough for screening."
