     The accompanying unaudited condensed consolidated financial statements have been prepared by management in accordance with the rules and regulations of the United States Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. Therefore, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2008. In the opinion of management, all adjustments, consisting solely of normal recurring adjustments necessary for a fair presentation of the financial information for the periods indicated, have been included. The results for the three-month period ended March 29, 2009 are not necessarily indicative of the results that may be expected for the year ending December 31, 2009.

     Use of Estimates

     The Company employs accounting policies that are in accordance with U.S. generally accepted accounting principles and require management to make estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported period. Significant estimates include those related to revenue recognition, allowance for doubtful accounts, valuation of inventories, valuation of long-lived assets, goodwill and other intangible assets, pension plan assumptions, income tax, valuation allowances, and litigation and environmental liabilities. Actual results could differ from those estimates.

     On January 1, 2009, the Company adopted Statement of Financial Accounting Standards No. 160, "Noncontrolling Interests in Consolidated Financial Statements, an amendment of ARB No. 51". Under the provisions of this statement, the income statement presentation has been revised to separately present consolidated net income, which now includes the amounts attributable to the Company plus noncontrolling interests (minority interests), and net income attributable solely to the Company. In addition, noncontrolling interests, formerly termed minority interests, are considered a component of equity for all periods presented. Noncontrolling interests were previously classified within other long-term liabilities. Prior year presentations have been restated to conform with the new statement

     Basic earnings per share are based upon the weighted average number of common shares outstanding during the period. Diluted earnings per share are based upon the weighted average number of common shares outstanding during the period assuming the issuance of common shares for all dilutive potential common shares outstanding.

The following table sets forth the computation of basic and diluted earnings per share:

6

     The weighted average diluted common shares outstanding for the three-months ended March 29, 2009 and March 30, 2008 excludes the dilutive effect of 799,716 and 315,799 options, respectively, as such options had an exercise price in excess of the average market value of the Company's common stock during such period.

     During the fourth quarter of 2007, the Company exited its Synsil^® Products product line and reclassified such operations as discontinued. Additionally, the Company reclassified to discontinued operations its two Midwest plants located in Mt. Vernon, Indiana and Wellsville, Ohio. These operations were part of the Company's Specialty Minerals segment. During 2008, the Company sold its idle Synsil operations and its facility in Wellsville, Ohio. The remaining assets of the Mt. Vernon operations are held for disposal.

     The following table details selected financial information for the discontinued operations in the consolidated statements of operations. The amounts exclude general corporate overhead and interest expense which were previously allocated to the entities comprising discontinued operations.

7

     The major classes of assets and liabilities held for disposal in the consolidated balance sheets are as follows:

     As of March 29, 2009, the Company had approximately $8.0 million of total unrecognized income tax benefits. Included in this amount were a total of $6.4 million of unrecognized income tax benefits that, if recognized, would affect the Company's effective tax rate. While it is expected that the amount of unrecognized tax benefits will change in the next 12 months, we do not expect the change to have a significant impact on the results of operations or the financial position of the Company.

     The Company's accounting policy prior to the adoption of FIN 48 and upon the adoption of FIN 48 is to recognize interest and penalties accrued relating to unrecognized income tax benefits as part of its provision for income taxes. The Company had a net reversal of approximately $0.6 million during the first three months of 2009, and has an accrued balance of $1.9 million of interest and penalties accrued as of March 29, 2009.

     The Company operates in multiple taxing jurisdictions, both within and outside the U.S. In certain situations, a taxing authority may challenge positions that the Company has adopted in its income tax filings. The Company, with a few exceptions (none of which are material), is no longer subject to U.S. federal, state, local, and European income tax examinations by tax authorities for years prior to 2003.

     The following is a summary of inventories by major category:

     The Company accounts for goodwill and other intangible assets in accordance with SFAS No. 142, "Goodwill and Other Intangible Assets." Under SFAS No. 142, goodwill and other intangible assets with indefinite lives are not amortized, but instead are tested for impairment, at least annually, in accordance with the provisions of SFAS No. 142.

8

     The carrying amount of goodwill was $66.1 million and $66.4 million as of March 29, 2009 and December 31, 2008, respectively. The net change in goodwill since January 1, 2009 was primarily attributable to the effect of foreign exchange.

     Acquired intangible assets subject to amortization as of March 29, 2009 and December 31, 2008 were as follows:

     The weighted average amortization period for acquired intangible assets subject to amortization is approximately 15 years. Estimated amortization expense is $1.2 million for each of the next five years through 2013.

     Included in other assets and deferred charges is an intangible asset of approximately $3.6 million which represents the non-current unamortized amount paid to a customer in connection with contract extensions at eight PCC satellite facilities. In addition, a current portion of $1.5 million is included in prepaid expenses and other current assets. Such amounts will be amortized as a reduction of sales over the remaining lives of the customer contracts. Approximately $0.4 million was amortized in the first quarter of 2009. Estimated amortization as a reduction of sales is as follows: remainder of 2009 - $1.1 million; 2010 - $1.2 million; 2011 - $0.9 million; 2012 - $0.6 million; 2013 - $0.6 million; with smaller reductions thereafter over the remaining lives of the contracts.

     Following an in-depth review of all our operations and development of a new strategic focus, the Company recorded a pre-tax charge of $16.0 million for restructuring and other costs during the second half of 2007. This charge consists of severance and other employee benefit costs, contract termination costs and other exit costs. Restructuring costs of $9.5 million were recorded in 2008 as part of this program, including a $6.8 million pension settlement loss related to the distribution of benefits.

     In the fourth quarter of 2008, the Company initiated an additional restructuring program through permanent reductions and layoffs. A restructuring charge of $3.9 million was recorded in the fourth quarter of 2008. Additional restructuring costs of $0.5 million were recorded in the first quarter of 2009 associated with this program. The restructuring will result in a total workforce reduction of approximately 475 employees, of which approximately 400 reductions have been implemented as of March 29, 2009.

     A reconciliation of the restructuring liability, as of March 29, 2009, is as follows:

     The following is a summary of long-term debt:

     As of March 29, 2009, the Company had $168.5 million of uncommitted short-term bank credit lines, of which approximately $10.9 million were in use.

     The Company and its subsidiaries have pension plans covering substantially all eligible employees on a contributory or non-contributory basis.

     Amortization amounts of prior service costs and recognized net actuarial losses are recorded, net of tax, as increases to accumulated other comprehensive income.

     The Company expects to contribute $6 million to its pension plan and $1.5 million to its other post retirement benefit plans in 2009. As of March 29, 2009, $0.5 million has been contributed to the pension fund and approximately $0.3 million has been contributed to the post retirement benefit plans.

10

     The following are the components of comprehensive income:

     The components of accumulated other comprehensive income, net of related tax, are as follows:

     SFAS No. 143, "Accounting for Asset Retirement Obligations" establishes the financial accounting and reporting obligations associated with the retirement of long-lived assets and the associated asset retirement costs. The Company records asset retirement obligations in which the Company will be required to retire tangible long-lived assets. These are primarily related to its PCC satellite facilities and mining operations. The Company has also adopted the provisions of FASB Interpretation No. 47, "Accounting for Conditional Asset Retirement Obligations," related to conditional asset retirement obligations at its facilities. The Company has recorded asset retirement obligations at all of its facilities except where there are no legal or contractual obligations. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset.

     The following is a reconciliation of asset retirement obligations as of March 29, 2009:

     Approximately $0.4 million is included in other current liabilities and $12.6 million is included in other non-current liabilities in the Condensed Consolidated Balance Sheet as of March 29, 2009.

The Board of Directors and Shareholders
Minerals Technologies Inc.:

     We have reviewed the condensed consolidated balance sheet of Minerals Technologies Inc. and subsidiary companies as of March 29, 2009, and the related condensed consolidated statements of income for the three-month periods ended March 29, 2009 and March 30, 2008, and the related condensed consolidated statements of cash flows for the three-month periods ended March 29, 2009 and March 30, 2008. These condensed consolidated financial statements are the responsibility of the company's management.

     We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

     Based on our review, we are not aware of any material modifications that should be made to the condensed consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

     We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Minerals Technologies Inc. and subsidiary companies as of December 31, 2008, and the related consolidated statements of income, shareholders' equity, and cash flows for the year then ended (not presented herein); and in our report dated February 25, 2009, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2008 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.
