Limestone deposits in the Coimadai area 10 kilometers north of Ballarat were first worked in the 1850s. The area was quarried for limestone for many years by various people and companies. The surveyor's name who produced this plan is inscribed on the map and below this is the name P. L. Alkemade, who presumably paid for the map to be produced. In 1886 Petrus Alkemade in partnership with Matthew Egan established the Alkemade Hydraulic Lime and Cement Company. The Alkemade family were involved in the limestone industry over several generations at Coimadai.Single page map showing part of the Limestone reserve near Coimadai in the Parish of Merrimu.
