Marketwired Canada
Orvana Minerals Corp. (TSX:ORV), through its wholly-owned subsidiary, Orvana
Resources US Corp ("Orvana USA"), announced today assays from 15 infill drill
holes on Copperwood S6 ("S6") mineralization located east of and adjacent to the
Copperwood copper deposit, Michigan, USA. These holes were part of a 4,930-metre
drill program that was completed on January 8 (see January 6, 2011 press release
available on the Company website www.orvana.com and SEDAR www.sedar.com). Based
on the sampling of 23 1950s drill-hole core and reject samples, an Indicated
resource of 8.41 million tonnes of 1.42 % copper was estimated for S6 (see
December 14, 2010 press release available on the Company website www.orvana.com
and SEDAR www.sedar.com). Results are summarized in the table below.

CW-11-143 190.0 191.8 1.8 1.29 1.8
Note: Total depths and total thicknesses are reported. The mineralized units
strike approximately 090 and dip approximately 7-12 degrees north. Multi-
shot surveys from these vertical holes showed that the deviation is
typically less than 1 degree. True thicknesses are between 96% and 99% of
the total thicknesses reported herein.
"With these data in hand, we can now proceed to update the resource estimates in
Copperwood and S6, which will lead to a revised mine plan that will include
resources from both areas" said Dr. Bill Williams, President of Orvana USA.
Marston and Marston of St. Louis, Missouri was retained to evaluate the combined
resource estimates in Copperwood and S6 with the purpose of including the latter
in the mine plan for the pre-feasibility study and mine-permit application.
Copperwood and S6 are sedimentary stratiform copper deposits hosted by the
Precambrian Nonesuch Formation. The mineralized unit, or the copper-bearing
sequence ("CBS"), lies at depths between about 30 metres (100 feet) and 265
metres (870 feet). The CBS is amenable to underground, room-and-pillar mining.
The mineralization is analogous to the White Pine mine, located 30 kilometres
(18 miles) to the east, where nearly 2 million tonnes of copper was produced
between 1953 and 1996.
Mineral resources that are not mineral reserves do not have a demonstrated
economic viability.
Theodore Bornhorst, Ph.D., who is an independent qualified person for the
purposes of NI 43-101, reviewed the assay results and verified the QA/QC. Copper
and silver were analyzed by accredited Activation Laboratories Ltd, (ACTLAB) in
Ancaster, Ontario Canada. Analytical procedures are the same as described in the
Copperwood Project NI 43-101-compliant Technical Report "Copperwood Project,
Michigan, USA", whose effective date is April 30, 2010.
A map showing the location of the drill holes is available on the Company's
website, www.orvana.com.
About Orvana
Orvana Minerals is a gold producer with a strong balance sheet and is
transforming itself into a multi-mine gold and copper producer. Orvana's primary
asset is the El Valle/Boinas-Carles ("EVBC") gold-copper project in northern
Spain, which is expected to be in production early in 2011. Orvana owns and
operates the Don Mario gold mine in Bolivia where the company is developing the
fully permitted copper-gold-silver Upper Mineralized Zone ("UMZ") deposit, which
is expected to commence initial production during the Spring of 2011. In
addition, Orvana is advancing its Copperwood copper project in Michigan, USA.
