A mine site in WA’s North West has put 20 of its workers into isolation as a precautionary measure against the deadly coronavirus. CITIC Pacific Mining – a Hong Kong listed company which is part of a larger Chinese conglomerate – has put the 20 workers from its Pilbara operations into isolation at its accommodation village 80km south of Karratha. The lockdown for the group comes after CPM isolated two staff members last month who had recently visited the Hubei province in China before a travel ban was put in place. Two employees were taken to Karratha Hospital yesterday morning where they were evaluated and considered not to be a coronavirus risk. The pair has since been put into isolation. A spokesman from the company said none of the workers were considered to be suspected coronavirus cases. One of the employees who visited Hubei has since left isolation while the second will finish their isolation in the next 24 hours. “During the weekend the company expanded its precautionary measures, in accordance with updated advice from public health authorities,” he said. “This included placing anyone who had visited China since January 17 into isolation for a 14-day period.

The spokesman said its actions had the support of WA’s Department of Health. “While this measure clearly comes at great inconvenience to our affected colleagues and is placing additional burden on site-based resources, the health and wellbeing of our staff and contractors remains our top priority,” he said. “The vast majority of staff and contractors are Australian residents. There is some impact on rostering … but it’s being managed for the moment. “We continue to keep relevant authorities and our staff and contractors regularly informed.” WA has no confirmed cases of the coronavirus which has killed hundreds in China. The last direct flight from China arrived in Perth earlier today after China Eastern and China Southern suspended their services.
