In February, 1956, after more than ten years of exploration, an INCO crew was drilling the anomaly at Cook’s Lake when rich deposits were found that would lead to the development of the Thomson mine.
Along with senior geologist Sac Crandall, Hugh S. Fraser was a geophysical party leader on that crew. In his book
A Journey North: The Great Thompson Nickel Discovery, he writes about the moment the core sample was revealed to Ralph D. Parker, then Vice President of INCO.
“
We showed Mr. Parker to the seat of honour behind the card table. We had a piece of core, perhaps 14 inches long, well studded with pentlandite, and everything was oriented so that this piece of core was sitting directly in front of Mr. Parker. He would get the maximum reflection from the eyes. We pulled a piece of newspaper in such a way that this 14 inch piece of core rolled out across the card table right at Mr. Parker. And he stopped, picked it up, looked at it, and his first words were, ‘Well, I’ll be damned! We’ve hit it!’" The
it referred to here is the discovery of the mother lode.
At first, INCO focussed its resources on development of a full mining operation at Moak Lake, "During 1953 and 1954, assays from the drilling at the Mystery/Moak Lake zone looked promising. INCO seriously considered the development of an open pit and underground mine, mill, refinery, railroad, power plant and town for 1,900 employees. A road system was built through the Belt between the two areas and plans were made to go underground at Moak. Over seven hundred tonnes of supplies and equipment were hauled into the area between January and April 1953."

It was decided that only the much richer Thompson orebody would be developed, however, and the Moak plans were scrubbed in favour of the Thompson site. On 5 December, 1956, the agreement upon which the Thompson project was based was signed by then Premier Duff Roblin and Inco President H. J. Wingate.
At that time, the single-resource community of Thompson was the western world’s only integrated nickel-mining, smelting, concentrating, and refining complex. Thompson was second only to Sudbury, Ontario as the largest nickel producer in the world.
Thompson was officially incorporated as a town in 1967 on Canada's Centennial Anniversary. Having reached a population of 20,000 in 1970, Thompson was then incorporated as a city in the presence of Queen Elizabeth II who, along with Prince Philip, Duke of Edinburgh and The Princess Anne
, visited Thompson in July of that year in celebration of the 100th Anniversary of Manitoba's entry into Confederation. Thompson would eventually become the third largest city in Manitoba—a status which it has since lost. The city remains one of the largest fully
planned communities in Canada.
Thompson has become an administrative, commercial and cultural centre with a proud Indigenous identity. Called “The Hub of the North,” Thompson services many of the small communities in the vast region that are only accessible by air or by winter roads.
