The mine continued to grow and in 1940 it was employing 140 workers, producing more tin than any field in Australia outside of Tasmania.
The Sydney Morning Herald described the shanty town that grew up alongside what was called the Gibsonvale mine as a "scene unknown
since the gold rush days".
Mining continued into the 1960s and 1970s. An alluvial tin treatment plant was built
at Gibsonvale in 1968. The plant was designed to produce 36 tonnes of tin concentrate per month, and the tin reserves were expected
to last for five years.
Instead, exploring an unsealed back road (at right), we passed the former Gibsonvale Tin Mines, which were spread over a relatively large area.
These were open cut mines, never restored, just water filled open cuts and rain washed heaps of pink
and white clay (below).
Tullibigeal is an old small rural town in this grain growing area. There was a modern Hotel. Grain from the
previous season was being carted out from the Graincorp receivals bin. The name is an Aboriginal word for "yarran wooden spears",
yarran being a native species of acacia.
We did not go passed the former township of Kikoira, which now has little more than a grain receivals bin, as the hotel closed in 1990 and is now derelict. Kikoira Road above, and sheep grazing, with or without the farmer's permission, in this rich green crop above right.
In 1938, John Gibson, a gold miner and prospector at nearby Weethalle, arrived at Kikoira in search of more gold. Instead of gold,
Gibson found a rich tin deposit. Gibson quickly developed a mine and by October that year, the mine was employing 21 workers. A "mild
rush" ensued with a large area around Kikoira pegged for mining claims by March 1939.
After seeing the Weethalle silos, our return was in part via narrow unsealed rural roads as we took a different route back to Condobolin.
These Graincorp silos were at the locality of Calleen, from where we continued on the West Wyalinbg - Condobolin Road back to
Condobolin.
