Forward-Looking Information. Certain information contained or incorporated by reference in this presentation, including any information as to our strategy, projects, plans or future financial or operating performance, constitutes "forward-looking statements”. All statements, other than statements of historical fact, are forward-looking statements. The words “believe”, "expect", “anticipate”, “contemplate”, “target”, “plan”, “intend”, “continue”, “budget”, “estimate”, “may”, “will”, “schedule” and similar expressions identify forward looking statements. Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by the company, are inherently subject to significant business, economic and competitive uncertainties and contingencies. Known and unknown factors could cause actual results to differ materially from those projected in the forward-looking statements. Such factors include, but are not limited to: fluctuations in the spot and forward price of gold and copper or certain other commodities (such as silver, diesel fuel and electricity); changes in national and local government legislation, taxation, controls, regulations, expropriation or nationalization of property and political or economic developments in Canada and other jurisdictions in which the Company does or may carry on business in the future; diminishing quantities or grades of reserves; increased costs, delays, suspensions and technical challenges associated with the construction of capital projects; the impact of global liquidity and credit availability on the timing of cash flows and the values of assets and liabilities based on projected future cash flows; the impact of inflation; fluctuations in the currency markets; operating or technical difficulties in connection with mining or development activities; the speculative nature of mineral exploration and development, including the risks of obtaining necessary licenses and permits; risk of loss due to acts of war, terrorism, sabotage and civil disturbances; changes in U.S. dollar interest rates and other operating currencies; risks arising from holding derivative instruments; litigation; business opportunities that may be presented to, or pursued by, the company; our ability to successfully integrate acquisitions or complete divestitures; employee relations; availability and increased costs associated with mining inputs and labor. In addition, there are risks and hazards associated with the business of mineral exploration, development and mining, including environmental hazards, industrial accidents, unusual or unexpected formations, pressures, cave-ins, flooding and gold bullion, copper cathode or gold/copper concentrate losses (and the risk of inadequate insurance, or inability to obtain insurance, to cover these risks). Many of these uncertainties and contingencies can affect our actual results and could cause actual results to differ materially from those expressed or implied in any forward-looking statements made by, or on behalf of, us. Readers are cautioned that forward-looking statements are not guarantees of future performance. All of the forward-looking statements made in this presentation are qualified by these cautionary statements. Specific reference is made to the most recent Annual Information Form on file with the Canadian provincial securities regulatory authorities for a discussion of some of the factors underlying forward-looking statements. The company disclaims any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise, except as required by applicable law.

Please see the Aranzazu Report and the appendix for the mineral resources statement. The Aranzazu Report is preliminary in nature. It includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the Aranzazu Report will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability

TSX: ORA 6Aranzazu: Expansion and Upgrade of Flagship Copper Asset Transformation of Aranzazu is ongoing, certain items are on hold pending completion of the financing

PEA published in August 2012 outlined key improvements Installation of roaster to reduce arsenic content in concentrate Increase capacity from 2,600 tpd to 4,000 tpd

Expansion capacity now fixed at 4,500 tpd by basic engineering (80% complete)

Roaster delivery is currently on hold pending completion of financing
