Orvana Announces Production and Exploration Update at El Valle-Boinas/Carles Gold/Copper Mine, Northern Spain

TORONTO, ONTARIO--(Marketwire - June 28, 2011) - Orvana Minerals Corp. (TSX:ORV) is pleased to announce that final approval has been received from the Ministry of the Environment for commercial production at its El Valle-Boinas/Carles ("EVBC") gold-copper mine in Northern Spain by Kinbauri Espana S.L.U. ("Kinbauri"), a wholly-owned subsidiary of Orvana.

EVBC initiated the start-up and commissioning of its mill May 31, 2011, and currently over 450 tonnes of copper-gold-silver concentrate have been produced with the first shipments trucked to port. The first revenues from the concentrate sales and dore is expected in July 2011.

EVBC is initially producing at 70% capacity, or about 1400 tonnes/day and production will increase to around 1900 tonnes/day when the shaft is completed in early 2012. Initial production will be primarily from lower grade skarn-type ore and lesser amounts from higher-grade oxidized ore zones. Consequently, during the initial production stages, head grades will be lower than in the future.

Shaft construction is progressing well, with over 170 metres of the 440-metre deep shaft reamed to a 5.5 metre diameter. With construction of shaft surface facilities expected to be started in August 2011, the shaft should be fully operational by March 31, 2012.

The approval from the Ministry of the Environment is subject to a final inspection and posting of a 5 million Euro bond within the next several weeks, and an additional 5 million Euro bond in one year from now.

Orvana is also pleased to provide drill results and an exploration update from deposits at EVBC.

The drilling is a part of a planned program that commenced in September, 2010; nearly 10,000 metres of drilling have been completed. The results reported herein are from A107, a subvertical structure, as well as the Boinas Este, Black Skarn, and Carles skarn bodies. Drilling in A107 and Carles was for stope definition and in the Boinas and Black Skarn deposits for resource delineation. Selected results are summarized in the table below.

Note: True thicknesses were determined graphically by measuring the distance approximately perpendicular to the contacts. No values were capped.

"These results not only increase our confidence in the existing reserve base in the A107 orebody, but have added to our resource inventory," said Agne Ahlenius, Director General of Kinbauri Espana S.L.U., a wholly-owned subsidiary of Orvana Minerals Corp. "The 3 rigs underground at EVBC will continue to drill strategic areas that will help us better define the mine plan as well as upgrade resources."

More information related to the EVBC geology and mineralization can be found on the Company's website www.orvana.com.

QA/QC

Security measures were taken to ensure the integrity and validity of the mineralization and proximal rocks in the new drill core under the supervision of Santiago Gonzalez-Nistal, Chief Geologist, Kinbauri Espana S.L.U., a qualified person for the purposes of NI 43-101. The core was sampled based on lithologic and alteration considerations. Assays were completed by ALS Chemex, except for samples from 11A1071001 and 1002, 11BE1019, 1021, 1022, 1023, and 1024, and 11V1202, which were analyzed at Kinbauri Espana SLU laboratory on site. The QA/QC protocol included internal and laboratory certified reference materials, blanks, duplicates and check assays. A 30-gram sample was analyzed by fire assay methods for gold and a conventional ICP-AES analysis was used for the analysis of 35 elements at ALS Chemex. Copper values exceeding 10,000 ppm and silver values exceeding 100 ppm were re-analyzed by atomic absorption using a 4-acid digestion. At the EVBC laboratory, a 30-gram sample was analyzed by fire assay methods for gold; and copper, silver, arsenic and antimony were analyzed by atomic absorption after an agua regia digestion. Pulps were sent to the ALS Chemex laboratory for check analyses.

Certain statements in this press release constitute forward-looking statements or forward-looking information within the meaning of applicable securities laws ("forward-looking statements"). Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions, potentials, future events or performance (often, but not always, using words or phrases such as "believes", "expects" "plans", "estimates" or "intends" or stating that certain actions, events or results "may", "could", "would", "might", "will" or "are projected to" be taken or achieved) are not statements of historical fact, but are forward-looking statements.

Forward-looking statements relate to, among other things, all aspects of the development of the Upper Mineralized Zone ("UMZ") deposit at the Don Mario Mine in Bolivia, the El Valle-Boinas/Carles project in Spain and the Copperwood project in Michigan and their potential operations and production; the outcome and timing of decisions with respect to whether and how to proceed with such development and production; the timing and outcome of any such development and production; estimates of future capital expenditures; mineral resource estimates; estimates of permitting time lines; statements and information regarding future feasibility studies and their results; production forecasts; future transactions; future metal prices; the ability to achieve additional growth and geographic diversification; future production costs; future financial performance, including the ability to increase cash flow and profits; future financing requirements; and mine development plans.

Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by Orvana as of the date of such statements, are inherently subject to significant business, economic and competitive uncertainties and contingencies.

Some of these risks, uncertainties and factors include fluctuations in the price of gold, silver and copper; the need to recalculate estimates of resources based on actual production experience; the failure to achieve production estimates; variations in the grade of ore mined; variations in the cost of operations; the availability of qualified personnel; the Company's ability to obtain and maintain all necessary regulatory approvals and licenses; the Company's ability to use cyanide in its mining operations; risks generally associated with mineral exploration and development, including the Company's ability to develop the UMZ deposit, the Copperwood project or the El Valle-Boinas/Carle's project; the Company's ability to acquire and develop mineral properties and to successfully integrate such acquisitions; the Company's ability to obtain financing when required on terms that are acceptable to the Company; challenges to the Company's interests in its property and mineral rights; current, pending and proposed legislative or regulatory developments or changes in political, social or economic conditions in the countries in which the Company operates; general economic conditions worldwide; and the risks identified in Orvana's Management's Discussion and Analysis for the period ended September 30, 2009 under the heading "Risks and Uncertainties".
