The “real” cause of the Lily mine collapse will be revealed by trade union Solidarity at a press conference to be held in Barberton on Thursday morning.

Solidarity general secretary Gideon du Plessis says the trade union has highly confidential information regarding the cause of the disaster which it has obtained in a reliable manner.

“The time has come to bring the guilty parties to book who are directly responsible for the disaster and the loss of precious lives,” Du Plessis said.

The Vantage Goldfields-owned Lily mine, situated just outside Barberton, in Mpumalanga initially collapsed on 5 February.

This event was  followed by a number of subsequent fall-of-ground incidents which took place throughout the month.

Three workers, Yvonne Mnisi, Pretty Mabuza and Solomon Nyarenda, were trapped when the lamp room container they were working in sank into a sinkhole created by a collapsed pillar underground at Lily mine.

So far, the search and rescue operation to recover the trapped workers was unsuccessful, with the latest recovery attempt expected to only resume in six months.

The Solidarity press conference will take place on Thursday 31 March at 10h00 at the Barberton Golf Club.
