Edmond Henry Horne, (born February, 1864 in Grandlake East, Oakfield, Nova Scotia, Canada) was a Canadian businessman and prospecter. He was the founder of Noranda, a mining and metallurgy company originally from Rouyn-Noranda, Quebec, Canada. He was first attracted by the general rock structure of the Rouyn area in 1911. Results of three subsequent trips to the Quebec township proved disappointing, but this Nova Scotia born millman had tenacity and his prospector's instinct refused to be downed. As a consequence in 1920 he succeeded in forming a syndicate of New Liskeard men to finance the staking and development of the present 600-acre area. The series of operations culminating in the incorporation under the Laws of Ontario of this great enterprise were started in August, 1922, when claims staked by Edmond 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.
Edmond Horne was the grandchild of Jacob Horne who fought at the battle at the Plains of Abraham. Jacob Horne was awarded land in Nova Scotia for his service.
In 1943 E.H. Horne returned to his home Enfield, Nova Scotia and donated funds to build a school. In his honour the school was named E.H. Horne.
Edmond Henry Horne died on March 15, 1953.
E.H. Horne was inducted into the Canadian Mining Hall of Fame in 1996.
