Overall Performance

The Company's operating and financial performance for Q3 2012 and the three months ended June 30, 2011 ("Q3 2011") as well as the nine months ended June 30, 2012 ("YTD 2012") and June 30, 2011 ("YTD 2011"), respectively, are summarized in the table below:

Operations

EVBC Mine, Spain

Operating and financial performance data for the EVBC Mine for Q3 2012 and YTD 2012 is set out below. The EVBC Mine was not in commercial production during the third quarter of fiscal 2011 having only reached commercial production in August 2011. Accordingly, comparative 2011 information is not provided.

The developments in both the Carlés and Boinás mines are progressing well. The new lower area in the Carlés Mine (-100 metre) started production during Q3 2012. In the Boinás Mine, the development and production from the higher grade San Martín area are ongoing. Head grades from both mines are improving. The shaft is in the process of being commissioned.

UMZ Mine, Bolivia

Operating and financial performance data for the UMZ Mine for Q3 2012 and YTD 2012 is set out below. The UMZ Mine was not in commercial production during the third quarter of fiscal 2011, having only reached commercial production in January 2012. Accordingly, comparative 2011 information is not provided.

During Q3 2012, the UMZ Mine produced a high-lead copper concentrate, an oxide cement and a talc-rich precious-metals concentrate. All three concentrate products are contracted for sale into the third quarter of fiscal 2013. In order to meet the requirements of such contracts, the Company plans to process oxide ore through the LPF circuit for approximately 15 days followed by approximately 45 days of flotation-only processing of transition ore at throughputs of approximately 1,500 and 2,700 tonnes per day, respectively, at 90% availability. There were two LPF-process campaigns during the third quarter of fiscal 2012 of 18 days and 16 days.

Copperwood Project, Michigan

Operating information for Orvana's Copperwood copper Project located in Michigan, United States, for Q3 2012 is set out below.

• In April 2012, Orvana received its mining permit from the Michigan Department of Environmental Quality ("MDEQ") as prescribed by Part 632 of the Non-Ferrous Metallic Mining regulation of the State of Michigan. This permit is the key stage gate for bringing the Copperwood Project into operation and indicates that the State of Michigan considers the project to have met all the necessary criteria to operate a mine in a responsible manner.
• In June 2012, the Wetlands Permit (Clean Water Act Section 404 Permit), the waste-water discharge permit, or National Pollutant Discharge Elimination Systems permit applications were the subject of a public hearing.
• In July 2012, the Company received the Permit to Install or Air Quality Permit from the Michigan Department of Environmental Quality, Air Quality Division.
• Total capital expenditures in respect of the Copperwood Project during the third quarter were $628 for a total of $3,245 for the nine months ended June 30, 2012.
• Orvana is continuing to investigate a variety of financing options, including the sale of an equity interest, debt and/or equity financing in order to bring the Copperwood Project into production.

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.

Orvana's short-term focus is operational optimization at the EVBC Mine and the UMZ Mine to generate increasing operating cash flows to pay down debt as well as advance the development of the Copperwood Project. Fiscal 2012 production guidance is 64,500 ounces of gold, 16.53 million pounds of copper and 625,000 ounces of silver. Mostly due to the delays related to the commissioning of the EVBC shaft, guidance for gold production is now expected to be approximately 60,000 ounces. However, due to exceptional performance at the UMZ Mine, guidance for silver is now nearly 700,000 ounces. Guidance for copper remains unchanged.

Fiscal 2012 total EVBC Mine production is targeted at 47,500 ounces (32,399 ounces to June 30, 2012), copper production at 4.41 million pounds (3.15 million pounds to June 30, 2012) and silver production at 125,000 ounces (92,395 ounces to June 30, 2012). Mine life is now projected at 10 years. Beyond 2012, Orvana will continue to work on improving head grade, increasing gold production and reducing total cash costs (by-product) per ounce of gold. Completion of the shaft will allow for more efficient ore extraction resulting in improved flexibility, increased mine production and cost optimization. Orvana will also investigate alternatives to maximize the mill output and enhance recoveries.

Fiscal 2012 total UMZ Mine production is targeted at 12.12 million pounds of copper (8.16 million pounds to June 30, 2012), 12,500 ounces of gold (8,374 ounces to June 30, 2012) and 575,000 ounces of silver (346,804 ounces to June 30, 2012). During the remainder of fiscal 2012, the Company's focus at the UMZ Mine will be on improving recoveries for both the LPF and flotation-only processes.

The Copperwood permit-review process will continue into the fourth quarter of fiscal 2012. Orvana will continue to investigate a variety of financing options, including the sale of an equity interest, debt and/or equity financing in order to bring the Copperwood Project into production.

Orvana's long-term focus is to utilize future cash flow and mining capabilities to build long-term value for its shareholders specifically through organic growth and possibly through certain strategic acquisitions primarily focused on advanced-stage gold and/or copper properties.

Executive Management Changes

Jim Jacques, Vice President of Operations, was promoted to Chief Operating Officer replacing Agne Ahlenius, who resigned, effective August 1. Jim Watt, an engineer with more than 40 years of primarily underground mining experience, has been retained as EVBC Director of Operations. On October 1, Francisco Fimbres, a metallurgist with over 30 years of experience, will assume the position of Director General, Kinbauri Espana S.L.U., a wholly-owned subsidiary of the Company that holds the rights at EVBC; he replaces Mr. Ahlenius in that role.

"Jim Jacques has contributed greatly to the turnaround of the Company and is well positioned to lead the production optimization effort at the highest of safety standards," said Bill Williams, President and Chief Executive Officer. "The combination of Messrs. Fimbres and Watt at EVBC will provide the expertise and leadership in order to expedite the optimization efforts at EVBC. We thank Mr. Ahlenius for his efforts in getting the EVBC Mine into commercial production and the shaft commissioned, and wish him success in his new role in the industry."
