RE: New hereThe UMZ is the open pit part of the current underground Don Mario mine in Bolivia.
It is expected to extend the current mine life to 2017.
Bolivia votes today on its new constitution. Its interesting that they delayed the release of the UMZ feasability study until after todays vote.
I repeat my conviction here that the UMZ will only proceed on Orvana's terms and those will have to be very favorable indeed, as they hold the hammer.
