Regarding the corruption case, the President Director of PT Timah Tbk, Ahmad Dani Virsal, finally speaks up. Virsal said that the estimated loss of Rp271 trillion is a calculation from experts brought by the Attorney General's Office. They cannot deny or provide other data. The figure of Rp271 trillion came from an environmental expert from the Bogor Agricultural Institute (IPB), Bambang Hero Saharjo. The number measures the ecological losses from tin mining activities.

"If it falls within the domain of environmental experts, then we cannot intervene, counter or do anything because it is announced by experts in their field," said Virsal. Meanwhile, he emphasized that an internal investigation had been conducted after several suspects were identified in the case that has been ongoing since 2015-2022. Virsal stated that the investigation process also sought to determine the actual losses incurred by PT Timah."
