“Leading by Example” Corporate Presentation March 2012 Cautionary Statement Certain statements contained in this presentation may constitute forward-looking statements. These statements relate to future events or the future performance of Rio Alto Mining Limited (“Rio Alto”). All statements, other than statements of historical fact, may be forward-looking statements. Forward-looking statements are often, but not always, identified by the use of words such as "seek", "anticipate", "plan", "continue", "estimate", "expect", "may", "will", "project", "predict", “propose”, "potential", "targeting", "intend", "could", "might", "should", "believe" and similar expressions. These statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forwardlooking statements. Rio Alto believes that the expectations reflected in those forward-looking statements are reasonable but no assurance can be given that these expectations will prove to be correct and such forward-looking statements included in this presentation should not be unduly relied upon by investors as actual results may vary. Unless required to be updated pursuant to securities laws, these statements speak only as of the date of this presentation and are expressly qualified, in their entirety, by this cautionary statement. This Presentation also discloses mineral resources. Mineral resources that are not mineral reserves do not have demonstrated economic viability. In particular, this presentation contains forward-looking statements, pertaining to the following: • capital expenditure programs and cash flow estimates; • development of deposits, resources and reserves; • treatment under regulatory regimes; • treatment under taxation regimes or other government financial regimes; • expectations regarding Rio Alto’s ability to raise capital; complete the feasibility study for the La Arena sulphide project; • work plans to be conducted by Rio Alto, and • the production of gold and copper from Rio Alto´s La Arena Project. With respect to forward-looking statements listed above and contained in this presentation, Rio Alto has made assumptions regarding, among other things: • the legislative and regulatory environment; • the impact of increasing competition; • current technological trends; • unpredictable changes to the market prices for gold and copper; • that costs related to development of the gold and copper properties and the development of gold and copper production projects will remain consistent with historical experiences; • anticipated results of exploration and development activities; and •Rio Alto’s ability to obtain additional financing on satisfactory terms. Rio Alto’s actual results could differ materially from those anticipated in these forward-looking statements as a result of the risk factors set forth below and elsewhere in this presentation: • uncertainties regarding the regulatory regime and the application approval process; • volatility in the market prices for gold and copper; • uncertainties associated with estimating and developing resources; • geological, technical, construction and processing problems; • liabilities and risks, including environmental liabilities and risks, inherent in developing gold and copper production projects; • fluctuations in currency and interest rates; • competition for, among other things, capital, acquisitions of reserves, undeveloped lands and skilled personnel; and • unpredictable weather conditions. Rio Alto’s plans and results could differ materially from those anticipated in these forward-looking statements as a result of these risk factors set forth above. Rio Alto recommends that you also review its most recent Annual Information Form and Annual MD&A for a discussion of other material risks that could cause actual results to differ significantly from current expectations. Rio Alto also cautions that mineral resources that are not mineral reserves do not have demonstrated economic viability.
