  27. 27. APPENDIX & FOOTNOTES 1. See slides below for the details of Pallancata and Rio Blanco reserve/resource estimates and the Converse, Goldfield and Gaby resource estimates. Inmaculada reserve and resource estimates are shown in slides 12 & 32. Please refer to the Company’s NI 43-101 reports and related news releases filed on SEDAR for a discussion of assumptions, parameters and material risk factors. Estimated mineral resources that are not mineral reserves do not have demonstrated economic viability. 2. The Inmaculada feasibility study information and reserve and resource estimates were announced in a news release dated January 11, 2012. A Technical Report on Inmaculada was filed by the Company on SEDAR on February 24, 2012. 3. The Goldfield feasibility study information and reserve and resource estimates were announced in a news release dated July 17, 2012. A Technical Report on Inmaculada was filed by the Company on SEDAR on August 31, 2012. 4. The Rio Blanco data for production, cash costs, capex and operating cash flow (slide 44) are presented on a pre-tax, pre- government royalty and pre-windfall tax basis, as reported in a Feb 19, 2009 Company news release about Rio Blanco’s updated costs. Life of mine production for the February 2009 estimate is based only on mineral reserves of the Alejandra North and San Luis deposits at Rio Blanco. 5. Gaby’s annual production, cash costs and capex estimates (slide 49) are sourced from an addendum to the preliminary feasibility study (PFS) announced in a January 29, 2009 Company news release. 6. Rio Blanco’s and Gaby’s outlook and production start-up estimates are dependent on continuation of project development pending a review of options to optimize value to shareholders. 7. Goldfield Main resource estimate is classified in accordance with CIM guidelines by independent consultant R. Mohan Srivastava, a Qualified Person under NI 43-101 and has an effective date of February 1, 2011. Gemfield reserve estimate was prepared by D. Anderson of Micon International Ltd (July 2012). Gemfield and McMahon Ridge resource estimates were calculated by R. Mohan Srivastava with an effective date of July 17, 2012. 8. IMZ uses the Gold Institute’s definition of “Total Cash Costs”. For Pallancata, IMZ’s Total Cash Costs per ounce of silver produced, net of gold credit, include mine operating costs, mined ore inventory adjustment, toll processing and mine general and administrative costs, Hochschild’s management fee, concentrate transportation and smelting costs, taxes (other than federal income tax) and Peruvian government royalty. Direct Site Costs per ounce silver comprise direct mining, mined ore inventory adjustment, toll processing and mine general and administrative costs (net of gold by-product credit). 9. IMZ accounts for its 40% ownership of the Pallancata Mine and the Inmaculada project on an equity accounting basis. 10. Production at Pallancata is shown from start-up of mining operations, September 2007.27

Numbers are rounded to reflect the precision of a resource estimate. 2. Measured and Indicated Resources include Proven and Probable Reserves. 3. Cut-off grade for estimated Reserves is 2.3 g/t gold equivalent. Cutoff grade for estimated Resources is 1.5 g/t gold equivalent. Gold equivalent ounces are estimated for mineral resources using a 60:1 silver to gold ratio. 4. The estimated mineral resources are not mineral reserves and do not have demonstrated economic viability. 5. To limit the influence of individual high-grade samples, grade capping was used. Gold assay grades were capped at 100 g/t and silver grades were capped at 5,000 g/t for the Angela vein which contributes 95% of the measured and indicated tonnage and 97% of the gold equivalent ounces. Minor veins were capped at variable values ranging from 5 g/t to 50 g/t gold and 500 g/t to 1,250 g/t silver. 6. An estimated dry bulk density of 2.51 tonnes per cubic meter was used for all mineralized rocks. 7. The grades were interpolated using the “Ordinary Kriging” estimation technique. 8. The contained metal reserve estimates include mining dilution (averaging 28% at a grade of 0.3 g/t Au and 11 g/t Ag) and 3% ore losses , but remain subject to process recovery losses. 9. The mineral resources were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM),Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council December 11, 2005. 10. The reserve and resource estimates have an effective date of January 11, 2012. 32

IMZ owns a 40% interest in the Inmaculada project. Under the joint venture agreement signed between IMZ and Hochschild, in December 2010, Hochschild must contribute the first $100 million of feasibility study, project development and capital costs with subsequent costs funded 60% by Hochschild and 40% by IMZ. Hochschild will receive a 7% management fee as operator of Inmaculada. Table does not consider the impact of these agreement terms. 2. Initial capital includes $25 million in contingency allowance and is based on Q4 2011 estimates. No escalation factors have been applied. 3. Direct site costs include mining, processing and mine administration. Total cash operating costs include direct site costs plus estimates of refining charges and government royalty (but do not include workers profit sharing which is 8% of net income). IMZ costs also include estimate of management fee. 4. Gold equivalent (“gold equiv.”) numbers are estimated using a silver-to-gold ratio of 60:1 calculated by using the ratio of the base case metal prices. 5. By-product accounting subtracts the revenue generated by silver from the total operating costs to determine the cost per ounce of gold. 6. For comparative purposes, if IMZ had selected co-product accounting, the resulting total cash operating costs on a 100% project basis are estimated to be $502/oz of gold and $8.20/oz of silver. 7. For comparative purposes, if IMZ had selected co-product accounting, the resulting total cash operating costs for IMZ’s 40% interest of the project are estimated to be $560/oz of gold and $9.15/oz of silver. 33
