27APPENDIX & FOOTNOTES1. See slides attached for the details of Pallancata and Inmaculada reserve/resource estimates. Please refer to theCompany’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 havedemonstrated economic viability.2. The Inmaculada feasibility study information and reserve and resource estimates were announced in a newsrelease dated January 11, 2012. A Technical Report on Inmaculada was filed by the Company on SEDAR onFebruary 24, 2012.3. The Goldfield feasibility study information and reserve and resource estimates were announced in a news releasedated July 17, 2012. A Technical Report on Inmaculada was filed by the Company on SEDAR on August 31, 2012.4. The 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, 2011.5. IMZ uses the Gold Institute’s definitions for costs per ounce: Direct Site Costs per ounce: direct mining costs; processing; mined ore inventory adjustment; mine G&Acosts; and by-product credits. Total Cash Costs per ounce: Direct Site Costs plus: management fees; product transportation, smelting andrefining costs; and taxes (other than federal income tax). Total Production Costs per ounce: Total Cash Costs plus: depreciation and amortization. Reclamation costsare not included by IMZ.6. IMZ also uses a non Gold Institute definition for costs per ounce: All-in Mine Costs per ounce: Calculated using the Gold Institute’s Total Cash Costs per ounce using by-product credits plus sustaining capital, mine development, exploration costs, workers’ profit sharing andproject-specific interest rate.7. IMZ accounts for its 40% ownership of the Pallancata Mine and the Inmaculada project on an equity accountingbasis.
28Pallancata - December 31, 2012 Reserves & ResourcesNotes: 1. Gold and Silver Eq. values based on 51:1 Ag/Au ratio, determined by using a combination of metal prices, metallurgical recoveries and cost of sales.2. Measured and Indicated Resources include Proven and Probable Reserves. CIM definitions were complied with for mineral resources and reserves.3. Cut-off grade of 128 g/t silver equivalent.4. Resource and reserve estimates have an effective date of December 31, 2012.5. Numbers have been rounded in all categories to reflect the precision of the estimates.6.

30Inmaculada, Peru - Reserves & Resources- January 20121. 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. Cut-off grade for estimated Resources is 1.5 g/t gold equivalent. Gold equivalent ounces areestimated for mineral resources using a 60:1 silver to gold ratio.4. The estimated mineral resources that are not mineral reserves do not have demonstrated economic viability.5. 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, 2005.6. The reserve and resource estimates have an effective date of January 11, 2012.Reserves MillionTonnesGold(g/t)Silver(g/t)Gold(oz)Silver(oz)Gold Equiv(oz)Proven 3.84 3.4 106 421,000 13,125,000 640,000Probable 3.96 3.3 134 424,000 17,796,000 707,000Proven & Probable 7.80 3.4 120 845,000 30,140,000 1,347,000ResourcesMeasured 3.28 4.1 128 430,000 13,500,000 655,000Indicated 3.78 4.1 159 490,000 19,300,000 812,000Measured & Indicated (2) 7.07 4.1 144 930,000 32,800,000 1,477,000Inferred Resources 4.94 3.9 152 620,000 24,200,000 1,023,000100% Project Basis, 40% Attributable to IMZBase-Case: $1,100 Gold, $18.00 Silver

IMZ owns a 40% interest in the Inmaculada project. Under the joint venture agreement signed between IMZ and Hochschild, in December2010, Hochschild must contribute the first $100 million of feasibility study, project development and capital costs with subsequent costsfunded 60% by Hochschild and 40% by IMZ. Hochschild will receive a 7% management fee as operator of Inmaculada.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 ofrefining charges and government royalty (but do not include workers profit sharing which is 8% of net income). IMZ costs also includeestimate 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 casemetal prices.5. By-product accounting is in accordance with the Gold Institute definition.
