Perhaps could try to getting someone like Clive Palmer or a domestic coal producer interested.An ASX listed company JMS primary business is mining in SA. they appear to be quite successful and are cashed up. Maybe they might show interest
I hit a brick wall trying to contact Clive but maybe others have connections.
Trying to solve the problem in SA will IMO be like banging u head against the wall
RES is ASX listed Co. Need an Australian angle to save it.
All IMO
