Shawn Thomas Kitchen, 24, of Whitehorse was the pilot of the aircraft. Julia Lane, 33, of Vancouver, was the passenger, according to the Yukon Coroner's Service.
The plane, a Cessna 208 Caravan operated by Alkan Air, was reported missing just after 12 p.m. local time on Tuesday after leaving Rackla, a mining airstrip about 150 kilometres northeast of Mayo. The aircraft was en route to Mayo.
The wreckage of the plane was located about 20 minutes by air from the Yukon community and both occupants were confirmed dead at the scene, Alkan Air said in a statement Tuesday.
The coroner's service says Lane was a managing partner of the geological consulting firm of Archer, Cathro and Associates. She had been working in the Rackla area.
According to a bio on ATAC Resources Ltd., the company exploring and developing the Rackla Gold Project, Lane worked in mineral exploration, predominantly in the Yukon, since 2006. She had been involved in the Rackla project since 2009. She was appointed vice president of exploration for ATAC in 2015 and had been a partner in Archer, Cathro since 2012.
Representatives from Archer, Cathro and Associates declined to comment.
The Transportation Safety Board said on Tuesday investigators will arrive in Mayo to begin investigating the incident on Thursday. It said the RCMP will assist investigators on reaching the remote site.
The Yukon Coroner's Service says it's investigating with the Transportation Safety Board, with assistance from the Mayo RCMP detachment.
