[ZEMEX LOGO] NEWS RELEASE FOR IMMEDIATE RELEASE ZEMEX CORPORATION ANNOUNCES FIRST QUARTER 2003 EARNINGS RESULTS TORONTO, ONTARIO - APRIL 23, 2003 - ZEMEX CORPORATION (NYSE, TSE: ZMX) announced today that net income of $0.01 per share for the first quarter ended March 31, 2003 unchanged from the first quarter of 2002. Revenue increased 35% from $15.0 million in the first quarter of 2002 to $20.2 million in the first quarter of 2003. Of the increase, 73% or $3.8 million was due to acquisitions completed in February and March of 2002. Operating income increased from $100,000 for the first quarter of 2002 to $600,000 for the current year period. Operating income was adversely impacted by operational problems experienced at the Spruce Pine feldspar plant and one time legal expenses associated with settlement of the Hecla Mining litigation. R. Peter Gillin, President of the Corporation, said, "In general, the industrial minerals business has been steady in most of our product lines and appears to be following seasonal patterns and strengthening into the second quarter." Our aluminum recycling group had a good first quarter continuing the turnaround that began in the third quarter of 2002. As previously announced, a Special Meeting of Securityholders is scheduled to be held on May 5, 2003 with respect to a proposed Plan of Arrangement. The proposed Plan of Arrangement, if approved by shareholders and optionholders and the court, will result in the acquisition by a controlled affiliate of Cementos Pacasmayo S.A.A. ("Pacasmayo") of all of the outstanding common shares and in-the-money options of Zemex on the basis of a cash price of US$8.80 per share. Pacasmayo is a publicly listed corporation on the Lima Stock Exchange (LSE), Peru and is related to the Hochschild Organization. Following approval by Securityholders, Zemex will seek court approval. The transaction is expected to be effective May 8, 2003.
