Cartage and treatment costs were very high and many mines starting up in the early 1900s could not afford to stay in business.

Records of 1908 show that 2,345 long tons (2,383 t) of ore were stacked ready for treatment, waiting for the completion of a reverberatory furnace.

Linedale's company constructed a road from their Ortona mine to Forsayth to connect with the Etheridge Railway.

On the opposite bank another hotel and kitchen, under the name of George Daly Ryan and next to it, a butcher shop with the name John Henry Clarke are also marked.

Later prospectors and fossickers were discouraged by a lack of available explosives, as well as ongoing drought conditions, and seemed unprepared to work such an isolated area.

[1] Ortona Mine and Battery is situated on the banks of the Percy River on a large area of land that crosses a series of small seasonally active creeks.

Surviving crushing and concentrating plant located on the site of the mill shed includes a jaw crusher, jigs, tables and a flat bed steam engine.

The mill shed has mostly collapsed, although some of the bush timber uprights and part of the roof frame, with corrugated iron sheets, remains standing.

Adjacent are the remains of two small buildings constructed with flagstone surfaces and stone pitched wall sections.

The structure closest to the mine complex has a ground surface area of 8 square metres (86 sq ft) and has a slate floor with an obvious edge.

[1] Ortona Mine and Battery was listed on the Queensland Heritage Register on 25 August 2000 having satisfied the following criteria.

The Ortona Mine and Battery is significant demonstrating the effort employed in the early exploration and development of mineral deposits, in this case, copper.
