The fact that none of its party's members may be able to physically do it is no problem because it has been tasked to a Sherpa mountain guide, Dorje Khatri, who would be climbing Everest for the 10th time on April 4.
It is not known whether Dorje's climb is being funded by the party or is doing it for a fee.
According to PBRS Api-Api Division chief, Dr Jay Rahman, eight delegates from his division would be leaving for Nepal on March 31 to hand over a customised flag to the Sherpa.
"Everest is the highest point on Earth and very few people have climbed to the top. We (PBRS) see it as a symbol of the greatest of all achievements.
"By flying our flag at the peak of Everest, it shows that PBRS and all the other BN component parties as well as Malaysians are capable of achieving the greatest of heights and challenges," Jay told a press conference, Friday.
He said once the Sherpa had reached the peak, he would take a photograph and send it back to Malaysia. "Even though we are not going to scale the mountain ourselves, it would be a great honour to see our flags flying at the top of the world and we are very fortunate to have Sherpa Dorje who is willing to help us achieve this dream," Jay said.
Jay said there are four main objectives for this mission, which is to instill unity among Malaysians, to ignite their spirit of love in the country, to bring the spirit of PBRS-BN all the way up to the peak of the world and reaching the top of the world symbolises achieving the greatest of all achievements.
"After the last General Election, we can see that unity among Malaysians was a little shaken and amid the MH370 tragedy, it is showing even more clearly now. In these hard times, we as Malaysians must be united as one and there should not be any divide among us if we are to achieve our aspirations to become a great country.
"Through this mission, we aim to achieve just that - to unite our people through something that all of us can be proud of and we are fortunate enough that there are companies that are willing to sponsor our mission," he said.
The mission to send eight delegates to Nepal will cost over RM30,000 and Renexus (M) Sdn Bhd has agreed to be the main sponsor together with Cham Enterprise, QMG Network and Flow Agency.
Joining Jay to Kathmandu would be PBRS Api-Api Secretary, Syamsurdi Salam, Women Chief, Jenny R Sedomon, Youth Secretary, Amir Omar, Division Committee Members Mohd Shahbudin Abdullah and Suhaili Ladis as well as PBRS Api-Api members Flora Binti Frans Niong and Nur Natasha Binti Sayrizal.
Sabah's first woman to climb Everest, Doris Jetirin Sitaun, is already on her way to the mountain's base camp and Jay said they only found out about her expedition last week. When they got in touch with her, she had already left for Nepal.
"It would have been a great opportunity for us to have Doris fly the flag had we found out about her expedition.
However, she is aware of our mission and we have made plans to meet up with her in Kathmandu during our trip, but that will depend on her climbing schedule.
"We are also giving Doris our full moral support and she will be updating us with her progress along the way and we will do what we can to support her," Jay added.
According to BN Kota Kinabalu Secretary, Randy KF Wong, who was also present during the press conference, BN and Parti Bersatu Sabah (PBS) would support PBRS in everything they do, especially in the Everest mission.
"We are very proud that a BN component party is making the effort to take on such a mission and we will support them all the way," said Wong.
