Senator Peck of Wyoming provided a lifetime of extraordinary leadership to the mining industry of his state. His boundless enthusiasm carried him to the heart of the Wyoming uranium discovery in 1953, the greatest uranium discovery in the United States. With the Gas Hills dotted with claims, the need arose for a state-wide mining association and, in 1956, he co-founded the Wyoming Mining Association. His newspaper, The Riverton Ranger, carried stories of the great uranium discovery. Later came the highly respected annual mining editions. He served as President of the Associated Press of Wyoming and of the Wyoming Press Association.​

His leadership extended into the halls of the Wyoming legislature, where he served 11 years. As Chairman of the Mines and Minerals Committee, he secured passage of responsible mine legislation. He pushed for the development of roads into the Gas Hills and secured uranium allocations to build much needed mills and transportation systems.  He was Founder and President of Western Standard Uranium.​

Peck contributed enormously to his state through philanthropic works. He helped found Central Wyoming College and served as Chairman of the Riverton Industrial Development Committee, encouraging high-tech industry to move into the area. Both the University of Wyoming and Central Wyoming College have memorial scholarships in his honor. For his great contributions to the mining industry and to Wyoming, the Wyoming Mining Association created the Roy Peck Community Service Award. The honor was awarded to him posthumously in 1983.​
