The warnings come after mining operations were suspended last October for several months following a mudslide that killed at least 28 people.
The Karenni State government has ordered the suspension of all mining operations in Mawchi, following a deadly mudslide that claimed the lives of 28 locals.
Twenty eight people have now been confirmed dead as a result of a disastrous landslide in eastern Burma on Sunday.
The death toll from the devastating mudslide in Mawchi has risen to 18, with dozens left homeless in the Karenni State town, according to relief workers.
The Mawchi mine in Karenni state was once the world’s most important source of tungsten, but locals there have now moved towards lead mining. The job is dangerous, however, as workers inhale toxic fumes and toil for hours in hazardous conditions.
Eumeralla and its local partner Myanmar Energy Resources Group are seeking to explore a 400km-square area in Karenni State.
