On Sunday, the company announced that a flash fire occurred in the dryer complex at the company’s Greenhills operation.

The company said that it was able to extinguish the fire quickly, but three employees were injured in the incident and have been treated for non-life threatening injuries.

The company has launched an investigation to determine the cause of the fire and said that it had no major impact to the operation of the company.

In 2010, four employees suffered from inhalation after a dryer explosion at the mine.

It also caused severe damage to the building and resulted in temporary shutdown of the mine, reported CBC News.
