Hollinger Consolidated Gold Mines

Hollinger Consolidated Gold Mines, Limited was a Canadian gold mining company that existed from 1916 to 1985. The mine was discovered on October 9, 1909, by Benny Hollinger, who found the gold-bearing quartz dike that later became known as Hollinger Mines. With his friend, professional prospector Alex Gillies, Hollinger had travelled to the Porcupine region in the wake of the Wilson expedition, which had recently discovered the future Dome Mine site. Hollinger and Gillies staked three claims each, and one for their former partner, Bernard "Barney" P. McEnaney, who had been unable to join them due to severe sciatica.

Hollinger sold his claim to a small syndicate led by Noah Timmins that, in 1910, incorporated as Hollinger Mines in Timmins, Ontario. The five venture partners were brothers Noah and Henry Timmins, brothers Duncan and John McMartin, and lawyer David Alexander Dunlap (for whom the David Dunlap Observatory was named). Hollinger Consolidated was formed in 1916 through the merger of Hollinger Gold Mines Limited, Acme Gold Mines Limited, and Millerton Gold Mines Limited.

The main Hollinger gold mine operated from 1910 until 1968. During that period 65,778,234 tons were milled, producing 19,327,691 ounces of gold, indicating an overall grade of 0.29. The value of the gold produced is placed at $564.7 million. In 1968 the company's name changed to Hollinger Mines Limited, and in 1979 to Hollinger Argus Limited.

Hollinger Consolidated Gold Mines was later acquired by Canadian tycoon E. P. Taylor's Argus Corporation. Argus was taken over by Conrad Black in 1978, and it was subsequently known as Hollinger Inc.
