Ayers was born at
Portsea,
Portsmouth, Hampshire, England, the son of William Ayers, of the Portsmouth dockyard, and Elizabeth, née Breakes. Educated at the Beneficial Society's School (Portsea) he entered a law office in 1832. Less than a month after his marriage in 1840, he emigrated with his wife, Anne (née Potts), to
South Australia, as a carpenter, with free passages. Until 1845, he worked as a law clerk, and was then appointed secretary of the
South Australian Mining Association, which owned the copper mine at
Burra Burra.
Henry Roach was chief Captain, responsible for day-to-day operations, from 1847 to 1867. Within a year the mine employed over 1000 men. For nearly 50 years, Ayers was in control of the operation, known as the "Monster Mine", initially as the secretary and later as the managing director. He made his wealth from the mine, which also secured the wealth of the colony of
South Australia. == Politics ==
