The consolidated financial statements and Management's Discussion & Analysis for the period ended March 31, 2012 are available on SEDAR and at www.orvana.com.

Outlook:

The forward looking statements made in this section are intended to provide an overview of management's expectations with respect to certain future operating activities of the Company and may not be appropriate for other purposes.

In the short term, Orvana is focused on its operations at the EVBC gold-copper-silver mine in northern Spain and its Don Mario Mine copper-gold-silver mine in eastern Bolivia as well as advancing its Copperwood copper project in Michigan.

During fiscal 2012, the Company expects gold production from EVBC to be about 52,000 ounces per annum, copper production about 2,000 tonnes per annum, and silver production about 125,000 ounces per annum. As head grades improve, cash cost per ounce of gold produced is expected to decrease. Mine life is now projected at 10 years. Beyond 2012, Orvana will continue to work on improving head grade, increasing gold production and reducing cost per ounce of gold produced. Completing the shaft, which is anticipated to take place during the third quarter of fiscal 2012, will allow for more efficient ore extraction, resulting in improved flexibility, increased mine production, and reduced costs. Orvana will also investigate alternatives to maximize the mill output and enhance recoveries, including a possible expansion of the mill in the future.

During fiscal 2012, the Company's focus at Don Mario will be on improving recoveries for both the LPF and flotation-only processing. Production in fiscal 2012 is expected to be about 5,500 tonnes copper, 12,500 ounces of gold, and 500,000 ounces of silver, respectively.

The Copperwood permitting process will continue during the third quarter of fiscal 2012. The Company will continue to investigate means of financing the project, including a joint venture partnership, debt financing, off-take agreement, and equity financing, among others.

Orvana projects total annual gold production to be approximately 64,500 ounces, total copper production to be 7,500 tonnes, and total silver production to be 625,000 ounces.

The Company will hold a conference call on Thursday May 17, 2012 at 10:00 a.m. (Eastern Time) to discuss the fiscal 2012 second quarter results. Following the presentation there will be a question and answer period for analysts and investors.

Non-IFRS Measures

The Company has used Non-IFRS measures, including direct mine operating costs, cash operating costs, total cash costs and total production costs, and related unit cost information, because it understands that certain investors use this information to determine the Company's ability to generate earnings as cash flow for use in investing and other activities. The Company believes that conventional measures of performance prepared in accordance with IFRS do not fully illustrate the ability of its operating mine to generate cash flow. Non-IFRS measures do not have any standardized meaning prescribed under IFRS, should not be construed as an alternative to IFRS reporting of operating expenses, and may not be comparable to similar measures presented by other companies. The measures are not necessarily indicative of cost of sales as determined under IFRS. Cash costs are determined in accordance with the former Gold Institute's Production Cost Standard. Cash costs for copper are determined in accordance with methods used by Brook Hunt.
