MinRes has been an industry leader in its COVID-19 response, acting early in March 2020 to secure PCR testing machines from Thermo Fisher in the US, establishing 10 drive-thru testing facilities in Perth and regional centres and employing 40 nurses.

The company has made its testing facilities available to more than 60 resources companies during the pandemic.

The company has rolled out SaferMe's innovative Bluetooth contact tracing technology across its sites and corporate offices in preparation for increased community cases in Western Australia.

Each card detects contact duration when one card comes into the range of another, taking the guesswork out of contact tracing and streamlining the process of identifying close contacts and activating control measures if a positive case is detected at one of the company's sites or offices.

MinRes chief executive, commodities Paul Brown said the company had a comprehensive management plan to prevent COVID-19 cases in the business and to quickly and safely manage cases if it did.

"Contact tracing will be an essential part of our response should we detect a positive COVID-19 case, ensuring we can keep our people, their families and our communities safe, and our operations running," he said.

"We've seen an extraordinarily positive response from our people to all the measures we've put in place to manage COVID-19 so far.

"I'm confident that when the borders are relaxed, our COVID-19 planning and preparations will ensure our workforce and business are well equipped to face the challenges ahead."

On Friday, WA's state mining engineer warned miners to be ready for COVID.

All mining operations need to appoint an infectious diseases manager and implement an infectious diseases management plan.

"The plan should include how operations can safely continue if key personnel (people in statutory positions) undergo periods of isolation - reliance on the potential for an exemption from the chief health officer is not an appropriate continuity response," Worksafe said.
