A new company was formed in 1882, merging the Prince of Wales and Bonshaw leases. The Bonshaw Freehold Company began in 1858 as a co-operative of 46 shareholders. They leased 180 acres from Jock Winter for five years. The mine manager was W.M. Acheson.

In 1862, the company purchased the land, and sank a second shaft, a half mile north-west of the first shaft. By the mid 1860's, large amounts of money was being invested into the company by Ballarat speculators and capitalists. The mine in its own right produced 96 520 ounces of alluvial gold, the sixth highest for the Ballarat goldfield.

When the leases merged in 1882, it covered 500 acres, with the company planning to sink a new shaft. J.A. Chalk is mine manager. A shareholder meeting in 1889 states operations had been suspended 'for some time'.

A new company was formed in 1891 over both leases. There was only a small number of shareholders, and limited capital. A new battery was erected, with operation confined to the 500 foot level on the reef found by the original Prince of Wales company. Little gold was found, and the company lasted until around 1900.
