2 presumptive COVID-19 cases at Mary River Mine, announces Nunavut’s top doctor

Nunavut’s chief public health officer announced two new presumptive cases of COVID-19 at the territory’s Mary River Mine on Wednesday — the second time a presumptive case has been announced at the mine this month.

The individuals are asymptomatic, said Chief Public Health Officer Dr. Michael Patterson in a news release. 

He said the two people, and their contacts, were immediately placed in self-isolation. 

Additional swabs were sent for testing to a southern lab to confirm the cases, said Patterson. The results are expected to come back early next week, he said.

“At this time, there is no evidence of transmission within the Mary River Mine site,” said Patterson in the news release. 

He said the territory’s public health team is ready to respond and give support, if needed. 

Patterson and Health Minister George Hickes are expected to provide an update about the presumptive cases at a news conference Wednesday at 2 p.m. ET. CBC will stream it live here and on its Facebook page.

Hickes said in the release that no Nunavut residents have worked at the mine since March, so the risk of COVID-19 spreading to the communities because of the two presumptive cases “remains very low.”

“We are actively monitoring this situation,” said Hickes.

The news release states that the two presumptive cases doesn’t affect the territory’s current public health measures in place.

2nd time in a month

The Mary River Mine is located about 176 kilometres southwest of Pond Inlet. This is the second time a presumptive case was announced at the mine this month.

A presumptive case of COVID-19 was reported there on July 2. The territory said on July 10 that the test came back negative after it sent the test to its accredited lab in Ontario.

The mine worker had tested positive twice on back-to-back days, but had not been showing symptoms; they were among several workers self-isolating since the case was first detected, the mine’s safety director said at the time. Patterson said on Friday that the mine worker and their contacts were taken off self-isolation.

Baffinland Iron Mines — which runs Mary River — said it was pleased with the negative test result on Friday. The company said its GuardRX mobile testing process at the site helped keep its site “COVID-19 free.”

Patterson said Monday during a press conference that the mine’s first presumptive case will remain presumptive.

“We can’t fully classify it,” Patterson said at the time. He said the mine was using test cartridges that weren’t compatible with verified labs used by the Nunavut government. The government sent the mine a supply of compatible swabs, he said.

Patterson also said Monday that the territory currently has a three-month supply of personal protective equipment in storage, at its current rate of usage.

Earlier in April, Nunavut’s top doctor announced the territory’s first case of COVID-19 in Pond Inlet, which was later determined to have been a false positive.

Nunavut is the only jurisdiction in Canada without a confirmed case of COVID-19 so far.

As of Monday, there were 163 people in the territory being investigated by public health for COVID-19. In total, 1,553 have been investigated.
