How to Avoid Rising Capital! and Operating Costs" Denver Gold Show September 8, 2008 Forward-Looking Statements Some of the statements contained in this presentation are forward-looking statements, such as statements that describe IRC's goals and expectations and IRCʼs estimated revenues from its royalties, production levels and mine life. Since forward-looking statements are not statements of historical fact and address future events, conditions and expectations, they inherently involve unknown risks, uncertainties, assumptions and other factors well beyond IRCʼs ability to control or predict. Actual results and developments may differ materially from those contemplated by such forward-looking statements. Material factors that could cause actual revenues to differ materially from any such forward looking statements include metal price fluctuations; interpretation of royalty contract terms; operatorsʼ production changes; mine developers abilities to develop, build and operate the mines; the effects of weather, operating hazards, adverse geological conditions, global warming, work slowdowns or stoppages, availability of labour, materials and equipment, changes in governmental laws, regulations, economic conditions or political instability; currency exchange rates; uncertainties involved in interpreting drilling results and other tests; possible variations in ore grade and recovery rates; risks of delays, accidents, equipment breakdowns; the possibility of unanticipated costs or expenses related to mining, processing, mine closures; and IRC's ability to acquire additional royalty interests. Forward-looking statements are based on the beliefs, estimates and opinions of management at the date the statements are made. IRC does not undertake to update forward-looking statements if managementʼs beliefs, estimates or opinions or other circumstances should change. 2 Important Notices Resource Estimates - All “reserve” and “resource” estimates included in this presentation were prepared in accordance with the Canadian Institute of Mining and Metallurgy classification system or the Joint Ore Reserve Committee as outlined in National Instrument (NI) 43-101 of the Canadian Securities Administrators and the Canadian Institute of Mining and Metallurgy Classification System. These standards differ significantly from the requirements of the U.S. Securities and Exchange Commission (SEC). In particular, “resources” are not the equivalent of “reserves” and the SEC does not normally permit the use of the term “resources” or of resource estimates in documents filed with the SEC. Accordingly, information included in the presentation may not be comparable to information disclosed by United States mining companies. IRC does not operate or explore but relies on others. Because it is not the operator, it must rely on decisions made by others, decisions on which it has little or no influence. It must also assume that public disclosure by its operators is accurate and true. Information contained herein is based on information made available by these operators. This presentation has been reviewed by a qualified person employed by SRK Consulting (U.S.) Inc, for the purposes of NI 43-101. See Company disclosure documents filed on SEDAR (www.SEDAR.com), including the Annual Information Form dated March 28, 2008, and the Companyʼs Annual Report on Form 40-F filed with the SEC (available at www.sec.gov <http://www.sec.gov> ). Trailing 12 monthsʼ (TTM) EBITDA, TTM adjusted EBITDA, TTM free cash flow per share, TTM EBITDA per share, EBITDA margins and EBITDA are non-GAAP financial measures. Such non-GAAP financial measures do not have any standardized meaning prescribed by Canadian GAAP and therefore may not be comparable to similar measures presented by other issuers. Management uses these measures internally. 3 Passive Foreign Investment Company PFIC NOTICE OF U. S. TAX INFORMATION FOR U. S. PERSONS This statement is provided for shareholders who are United States persons for purposes of the U.S. Internal Revenue Code. It is not relevant to other shareholders. NOTICE PURSUANT TO IRS CIRCULAR 230: ANYTHING CONTAINED IN THIS NOTICE CONCERNING ANY U.S. FEDERAL TAX ISSUE IS NOT INTENDED OR WRITTEN TO BE USED, AND IT CANNOT BE USED BY A U.S. HOLDER, FOR THE PURPOSE OF AVOIDING FEDERAL TAX PENALTIES UNDER THE INTERNAL REVENUE CODE.

International Royalty Corporation ("IRC") believes that it is currently a Passive Foreign Investment Company ("PFIC") as defined in Section 1297 of the Internal Revenue Code. Certain U. S. income tax consequences flow from this designation and these tax consequences may be mitigated by electing to treat IRC as a Qualified Electing Fund ("QEF").

Capital Costs! Operating Costs! IRR1! +44%! +20%! +20%! Based on mean after-tax calculations only Costs Rising Faster than Returns 6 Macro Reasons for Changes Different types of feasibility studies Pre-feasibility (Scoping, PEA) => Feasibility => Bankable Feasibility Study => Production Different levels of feasibility studies have different confidence levels: Stage Pre-feasibility: Feasibility: Bankable Feasibility: Range 5.0% -30.0% 5.3% - 16.9% 10.0% - 15.0% Different time periods between disclosures Changes in scope Must Make Adjustments Prior to Drawing Judgments 7 Micro Reasons for Changes Price inflation: diesel, raw materials, labor Currency exchange rates Time delays Inclement weather Customs holdups Backlogs in equipment deliveries by manufacturers Lengthier permitting times Special interest group obstructionists Not All Increases are Related to Inflation 8 Total Change Capital and Operating Costs are Rising 9 Change Per Year Adjusting for Time Periods Shows the Rise is Worse than Expected 10 Pre- and After-tax Mean IRRs Pre- and After-Tax IRR Range of 15.5% to 28% 11 Conclusions Rise in Costs Per Year! 1 Average Return! Capital Costs! Operating Costs! IRR1! +44%! +20%! +23%/ +20%! Based on mean after-tax calculations only. IRR figures are pre- and after-tax, respectively. When Costs Rise More Than IRR, One is Either Trading Dollars or Losing Money 12 How does one invest in commodities yet avoid these capital and operating costs overruns? 13 Royalty Companies Maximum Exposure to Upside 14 ~85 High Quality Mineral Royalties Australia ~13 Royalties North America / Latin America ~65 Royalties Europe / Africa ~7 Royalties 95% in Secure Investment-Grade Countries 15 Company Overview TSX: IRC, AMEX: ROY ~85 diversified mineral royalties Trailing 12 month Revenue: $45.4 million Trailing 12 month EBITDA: $26.3 million Annual Dividend: US$0.04 per share Market Cap: ~US$250 million North Americaʼs fastest growing Diversified Mineral Royalty Company As of 6/30/08 16 IRC Investment Highlights 1.
