Earlier, the operations had been suspended in the underground workplaces that was issued pursuant to section 54 of the Mine Health and Safety Act (South Africa) by the Department of Mineral Resources (DMR) on 16 November 2010.
The company said that the notice was issued in connection with a fall of ground, which claimed the life of one employee.
First Uranium president and chief executive officer Deon van der Mescht said that following an assessment by the DMR, the notice was lifted on the condition that each panel is declared safe before blasting may resume.
"We are satisfied that we fully understand the cause of the accident and have increased training and awareness initiatives around standard safety procedures in unsupported areas," Mescht said.
