- Citigold is celebrating the 150th anniversary of the discovery of gold at Charters Towers.
- CTO is advancing on mine design and engineering for Central Mine ahead of the mining restart process.
- The latest round of infill rock chip and float sampling highlights potential gold mineralisation in the northern part of Citigold’s mining titles.
While the rest of the world was celebrating Christmas and year-end holidays, Citigold Corporation (ASX:CTO) had one more reason to celebrate. The golden date “24 December 2021” marked the 150th anniversary of the discovery of gold at Charter Towers.
It was the year 1871 when a young 12-year-old lad named Jupiter Mosman stumbled upon a glittering rock near streams. Jupiter was a member of a prospecting team when he discovered gold, which led to the birth of Charters Towers town in Queensland.

Picking up steam, Charters Towers soon became Australia’s fifth-largest gold producer. At its peak, it was home to nearly 30,000 miners. It is estimated that the goldfield has produced more than 6.6 million ounces of gold between 1872 to 1917.
Citigold has released its activities report for the quarter period ending 31 December 2021. During the reporting period, CTO’s technology-driven ‘ultra-low-cost mining’ initiative included the selection of the site for the processing plant. The location of the plant has been decided to be situated near the Central Mine with excellent connectivity to the highway.
Citigold’s evolving new process plant design will focus on upgrading ores to remove the bulk of the granite dilution, which is normal in underground mining operations. The plant design incorporates the latest technologies available with special emphasis on making it greener.
Furthermore, Citigold intends to achieve environmentally friendly and green gold mining and processing operations. So, the upcoming plant will have an efficient design with a lesser ground footprint. The plant would require lesser water with a provision to use renewable power.
The Central Mine that will see the first production of gold after the restart of the mine is in excellent condition. The production-ready surface infrastructures are all in place and well maintained. Citigold had identified challenges from previous gold production test mining in a usual way and believes it has overcome these challenges with advances in technology and modern innovative thinking. The Company and its consultants are constantly making efforts to develop an efficient system.
In its endeavour to develop efficient mining operations, Citigold has come out with a ‘keyhole mining’ approach. For its unique geometry of the ore system, the mining team would require making small excavations and extracting valuable ore only. This will lead to minimum dilution and lesser processing of waste.

Resource potential of Charters Towers Gold Project
The Probable Ore Reserve of the project is currently estimated at 2.5 Mt with an average grade of 7.7g/t Au with contained gold of 620,000 ounces and the cut-off grade is 4.0g/t Au. The project possesses an Inferred Mineral Resource of 14Moz with an average grade of 14.0g/t.
During the December quarter, the resource potential of the Company remained unchanged. The recent infill rock chip and float sampling operations over the exploration permit area have indicated the presence of anomalous gold in an area of interest to the north of Charters Towers.
Citigold will carry on further investigation work to determine the source of anomalous samples. Further exploration work would include mapping and sampling of rock outcrops in the creek’s upstream direction.
Shares of CTO are trading at AU$0.008 with a market cap of AU$22.66 million as of 3 February 2022.
