Orvana Minerals Corp. (ORV.TO), through its wholly-owned
subsidiary, Empresa Minera Paititi (EMIPA), today provided an
updated resource and reserve estimates for its Don Mario UMZ
copper-gold-silver mine operations in Bolivia. During 2012, EMIPA
made significant changes to the mining and processing aspects of
the operation thus warranting an update.
The updated NI 43-101-compliant resource and reserve estimates
contains approximately 177,000 ounces of gold, 5.6 million ounces
of silver, and 120 million pounds of copper, which is a decrease of
about 5%, 2%, and 11%, respectively, after considerations for
production through September 30, 2012 as well as the exclusion of
certain oxide mineralization whose metals cannot be extracted
economically; testing of these ores will continue in order to seek
a viable extraction method, Orvana said.
Orvana is very near a yr low of 78 cents.
