Rescue teams in Zimbabwe are continuing the search for survivors, three days after a disused gold mine in the country’s Chegutu district collapsed, killing at least 10 illegal miners. Around 42 artisanal miners were believed to be working underground at the Bay Horse Mine in Chegutu when it caved in on them on Friday, provincial official Marian Chombo told local media Sunday. Twenty-one of them have been rescued while another 10 are believed to be trapped in the rubble, according to local reports. Artisanal mining is common in Zimbabwe, which is rich in vast deposits of gold and diamonds. Accidents at illegal mining sites are also common in the southern African country.
