Theta Project development
Theta Gold Mines is continuing development at its Theta Starter Project in South Africa with the arrival last month of the 2.5-megawatt ball mill purchased in October 2019.
The mill was transported from Rustenburg on a six-day journey to the Theta Project site at Pilgrim’s Rest, Mpumalanga.
Chairman Bill Guy said the small Pilgrim’s Rest community welcomed the arrival of the mill with much excitement, eager to see the progress towards an official start of construction and mining which will bring back much-needed jobs and income for the town.
He said: “The company has achieved another milestone in the development of the Theta Project.
“The mill arrival and a welcome march from the local community was very heartening.
“The mill was placed on the permitted mine site, ready for future installation.”
