In 1908, Horne caught wind of the silver discoveries in Cobalt, Ontario and travelled back to the area.
Results of three subsequent trips to the Quebec township proved disappointing, but had the tenacity and prospector's instinct that refused to be downed.
The series of operations culminating in the incorporation under the Laws of Ontario of Noranda were started in August, 1922, when claims staked by Edmund Horne in Rouyn Township, Quebec, were optioned by a syndicate formed a few months previous for the purpose of exploring promising areas, the acquirement of claims and the general development of mining properties.
The Horne claims, together with a number of other properties that had been acquired developed Noranda into an outstanding copper-gold producer.
[3] E. H. (Edmund Henry) Horne married later in life and returned to his hometown of Enfield, Nova Scotia.
Edmund and his wife Anna lived at Monte Vista, their 1,000-acre (4.0 km2) farm on Grand Lake, on the outskirts of Enfield.
A few years after Edmund's death, Anna gifted their estate of Monte Vista to the Oblates of Eastern Canada.
