Exhibit 99.1

Mine Safety Disclosure

     Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, each operator of a mine is required to include certain mine safety results in its periodic reports filed with the SEC. Our manufacturing plants process mined minerals, and therefore are viewed as mine operations and are subject to regulation by the federal Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977 (Mine Act). Below, we present the following items regarding certain mining safety and health matters for the three months and year ended December 31, 2010:

	-		total number of violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a mine safety or health hazard under section 104 of the Mine Act for which we have received a citation from MSHA;
	-		total number of orders issued under section 104(b) of the Mine Act, which covers violations that had previously been cited under section 104(a) that, upon follow-up inspection by MSHA, are found not to have been totally abated within the prescribed time period, which results in the issuance of an order requiring the mine operator to immediately withdraw all persons (except certain authorized persons) from the mine;
	-		total number of citations and orders for unwarrantable failure of the mine operator to comply with mandatory health or safety standards under Section 104(d) of the Mine Act;
	-		total number of flagrant violations (i.e., reckless or repeated failure to make reasonable efforts to eliminate a known violation of a mandatory health or safety standard that substantially and proximately caused, or reasonably could have been expected to cause, death or serious bodily injury) under section 110(b)(2) of the Mine Act;
	-		total number of imminent danger orders (i.e., the existence of any condition or practice in a mine which could reasonably be expected to cause death or serious physical harm before such condition or practice can be abated) issued under section 107(a) of the Mine Act;
	-		total dollar value of proposed assessments from MSHA under the Mine Act;
	-		total number of mining-related fatalities; and
	-		total number of pending legal actions before the Federal Mine Safety and Health Review Commission involving such mine.

     In addition, as required by the reporting requirements regarding mine safety included in §1503(a)(2) of the Dodd-Frank Act, the following is a list for the three months and year ended December 31, 2010, of each mine of which we or a subsidiary of ours is an operator, that has received written notice from MSHA of:

(a) a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of mine health or safety hazards under §104(e) of the Mine Act:

          None

(b) the potential to have such a pattern:

          None.

     Citations and orders can be contested and appealed, and as part of that process, are sometimes reduced in severity and amount, and are sometimes dismissed. The number of citations, orders, and proposed assessments vary by inspector and also vary depending on the size and type of the operation.

     The SEC recently proposed Item 106 of Regulation S-K (17 CFR 229.106) to implement section 1503(a) of the Dodd-Frank Act regarding mine safety reporting. It is possible that the final rule adopted by the SEC will require disclosures to be presented in a manner that differs from this presentation.
