Hundreds of climbers had to abandon their attempts when an avalanche struck Everest base camp, killing 18 people and marking a second year with virtually no summits after the deaths of 16 Nepalese guides in 2014 sparked a shutdown of the world's highest peak.
The twin quakes that struck the Himalayan nation on April 25 and May 12 killed more than 8,600 people and destroyed the popular Langtang trekking route, raising fears for the immediate future of the tourism industry.
"Although no decision has been taken yet, no one wants to be negative about (extensions)... We have to take the perspective of climbers and tourism operators into account," Gautam said.
The government, following the 2014 shutdown, had offered a five-year extension to 334 climbers, many of whom returned to Everest in April, days before an avalanche wiped out part of base camp in the worst disaster to hit the 8,848-metre (29,035-foot) high peak.
