Norman W. Byrne was born in Sault Ste. Marie, Ontario on February 17, 1912. Although he had first travelled to the NWT with his father, who was a prospector, and his brother Jerry in 1932, he returned to McGill to complete his studies. In 1936 after graduating from McGill University with a degree in Mining Engineering, he moved to Gold Fields (Uranium City) and later to Outpost Island where he worked as a Mine Engineer. In 1940, with the closure of the mine at Outpost Island, Byrne moved to Whitehorse where he worked on the Canol Pipeline. In 1945 Byrne moved to Yellowknife and was asked to survey the Discovery claims. Byrne was so impressed with the claim that he, along with his father and brother, purchased it. Mining work then began at the Discovery Mines Limited property and on February 10, 1950 the first gold brick was poured. After the first 17 years of operation, over $35 million had been extracted from the Discovery Mines Limited claim.
Despite Byrne's involvement with the Discovery claims, he continued to work as a consultant
Mining Engineer. He was also involved in developing Rayrock Mines Limited, Northland Mines Limited and Tundra Mines Limited. In 1964 Byrne began a second career as a real estate developer in Yellowknife and his company constructed many houses and apartment buildings in the town. He was a strong supporter of the lobby group working to have the capital city of the NWT established at Yellowknife rather than at Fort Smith. He was also actively involved in many community organisations in Yellowknife and was a vocal advocate of the establishment of a separate Catholic school system in the community.
He was the chairman of the Separate School Board from its inception in 1951 until his death on November 14, 1973.
