In certain cases, forward-looking statements can be identified by the use of words such as plans, expects, is expected, budget, scheduled, estimates, forecasts, intends, anticipates or believes, or variations of such words and phrases or statements that certain actions, events or results may, could, would, might, or will be taken, occur or be achieved, or the negative of these words or comparable terminology. Forward-looking information includes statements respecting currently ongoing matters which will continue and statements in the present or past tense which are not historical facts. By their very nature forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual performance of the Company to be materially different from any anticipated performance expressed or implied by the forward-looking statements. Such factors include various risks related to the Company s operations, including, without limitation, fluctuations in spot and forward markets for gold, silver and other metals, fluctuations in currency markets, changes in national and local governments in Mexico and the speculative nature of mineral exploration and development, risks associated with obtaining necessary exploitation and environmental licenses and permits, and the presence of laws that may impose restrictions on mining, and risks associated with the Company s ability to defend the validity of the APA. A complete list of risk factors are described in the Company s annual information form and will be detailed from time to time in the Company s continuous disclosure, all of which are, or will be available, for review on SEDAR at This presentation uses the terms measured resources, indicated resources and inferred resources. The Company advises readers that although these terms are recognized and required by Canadian regulations (under National Instrument Standards of Disclosure for Mineral Projects ( NI ), the United States Securities and Exchange Commission does not recognize them. Readers are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted in to reserves. In addition, inferred resources have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, or economic studies, except for a Preliminary Assessment as defined under NI Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable. Although the Company has attempted to identify important factors that could cause actual performance to differ materially from that described in forward-looking statements, there may be other factors that cause its performance not to be as anticipated. The Company neither intends nor assumes any obligation to update these forward-looking statements or information to reflect changes in assumptions or circumstances other than required by applicable law. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those currently anticipated. Accordingly, readers should not place undue reliance on forward-looking statements. Unless otherwise indicated, all dollar values herein are in US$. 2

11 Strategic Review Process PRIMERO Board initiated a strategic review process to explore alternatives to improve shareholder value. Primero has signed a definitive agreement with McEwen Mining for the sale of the Black Fox Complex for $35M, subject to certain adjustments at closing. The transaction expected to close in early-october. Primero received numerous proposals to acquire San Dimas and other assets. All San Dimas proposals were based on a reduced silver streaming arrangement. All proposals impacted by numerous factors: > Operational challenges in the past 18 months, > Tax dispute in Mexico, > Lack of exploration success, > Recent strike and labour disruptions in Mexico. Currently in discussions focused on potential changes to the streaming agreement and the distribution of proceeds among stakeholders including Wheaton Precious Metals ( WPM ). No certainty these discussions will result in a resolution acceptable to all stakeholders including WPM. 11

25 Notes to Investors Regarding the Use of Resources This presentation has been prepared in accordance with the requirements of Canadian provincial securities laws which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all mineral reserve and resource estimates included in this presentation have been prepared in accordance with Canadian National Instrument Standards of Disclosure for Mineral Projects ( NI ) and the Canadian Institute of Mining, Metallurgy and Petroleum classification systems. NI is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards differ significantly from the requirements of the United States Securities and Exchange Commission (the SEC ), and reserve and resource estimates disclosed in this presentation may not be comparable to similar information disclosed by U.S. companies. The mineral reserve estimates in this presentation have been calculated in accordance with NI , as required by Canadian securities regulatory authorities. For United States reporting purposes, SEC Industry Guide 7 under the United States Securities Exchange Act of 1934, as amended, as interpreted by Staff of the SEC, applies different standards in order to classify mineralization as a reserve. As a result, the definition of probable reserves used in NI differs from the definition in the SEC Industry Guide 7. Under SEC standards, mineralization may not be classified as a reserve unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify mineralized material as reserves under the SEC standards. Accordingly, mineral reserve estimates contained in this presentation may not qualify as reserves under SEC standards. In addition, this presentation uses the terms indicated resources and inferred resources to comply with the reporting standards in Canada. The Company advises United States investors that while those terms are recognized and required by Canadian regulations, the SEC does not recognize them. United States investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into mineral reserves. Further, inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, United States investors are also cautioned not to assume that all or any part of the inferred resources exist. In accordance with Canadian securities laws, estimates of inferred resources cannot form the basis of feasibility or other economic studies. It cannot be assumed that all or any part of indicated resources or inferred resources will ever be upgraded to a higher category or are economically or legally mineable. In addition, disclosure of contained ounces is permitted disclosure under Canadian securities laws; however, the SEC only permits issuers to report mineralization as in place tonnage and grade without reference to unit measures. NI also permits the inclusion of disclosure regarding the potential quantity and grade, expressed as ranges, of a target for further exploration provided that the disclosure (i) states with equal prominence that the potential quantity and grade is conceptual in nature, that there has been insufficient exploration to define a mineral resource and that it is uncertain if further exploration will result in the target being delineated as a mineral resources, and (ii) states the basis on which the disclosed potential quantity and grade has been determined. Disclosure regarding exploration potential has been included in this presentation. United States investors are cautioned that disclosure of such exploration potential is conceptual in nature by definition and there is no assurance that exploration will result in any category of NI mineral resources being identified. 25
