Exhibit 99.1 - Press Release

CORPUS CHRISTI, Texas, April 30, 2013 - TOR Minerals International (Nasdaq: TORM), producer of synthetic titanium dioxide and color pigments, specialty aluminas, and other high performance mineral fillers, today announced its financial results for the first quarter ended March 31, 2013. Highlights for the first quarter of 2013 as compared to the first quarter of 2012 included:

* BARYPREM sales have been reclassified from Specialty Aluminas to "Other" which consists of Barium Sulfate and Other Specialty Minerals to make comparisons more meaningful.

Net sales decreased 11 percent during the first quarter of 2013, as a 25 percent decrease in TiO2 Pigment sales was only partially offset by a flat year-over-year comparison in specialty alumina sales and a 7 percent increase in other specialty minerals. As expected, sales volumes of Titanium dioxide (TiO2) pigment products, which include HITOX®, TIOPREM® and synthetic rutile (SR) products, continued to be adversely affected by weakness in the broader market for TiO2. Pricing of TiO2 products were relatively unchanged year over year. The flat comparison in Specialty alumina sales, which includes the ALUPREM®, HALTEX® and OPTILOAD®, was primarily related to the order patterns of a large U.S. customer and shift in product mix to lower priced products, offsetting increasing sales in Europe. Barium Sulfate and other product sales increased 7 percent, primarily due to increased volumes from new and existing BARTEX® customers in the United States.

During the first quarter of 2013, gross margin decreased to 13.1 percent of sales, versus 24.9 percent during the same period a year ago. Almost half of the decrease in gross margin was related to lower utilization of the SR production plant in Malaysia. As previously disclosed, the Company's SR production plant was shut down for the entire first quarter to perform significant construction and maintenance work. In addition to lower fixed cost absorption at the Malaysia plant, lower sales volumes and increased input costs also contributed to the decrease in gross margin. Pricing for TiO2 pigments and Aluminas were relatively unchanged year over year. Operating expenses increased 9.6 percent to $1.4 million, primarily related to increased staffing levels and research and development expenses. During the first quarter, the net loss available to common shareholders was ($75,000), or ($0.03) per diluted share, as compared to net income of $1.4 million, or $0.41 per diluted share, during the same period a year ago.

"While improving, inflated customer inventory levels and soft demand trends have led to decreased volumes and pricing across the TiO2 industry. We expect these market conditions to persist through the first half of 2013 and will likely continue to negatively affect both sales volumes for our TiO2 pigments and third-party sales of SR for the next several quarters. Due to the value-added nature of our TiO2 products, relative to commodity TiO2 producers, we have been able to maintain pricing discipline. In addition, we continue to innovate and have had success with our new TiO2 product, TIOPREM, which saw a 73 percent growth during the first quarter and represented 13 percent of TiO2 product sales. Longer term, we believe the demand and supply characteristics in the TiO2 industry will continue to create attractive opportunities for TOR Minerals, as customers increasingly discover the value-added attributes of substituting our HITOX® and TIOPREM® products for commodity TiO2," said Dr. Olaf Karasch. "On the cost side, we expect near-term profitability to continue to be negatively affected by increased costs of raw materials and energy. However, fixed cost absorption in our Malaysian SR plant should improve through the balance of the year as we have reduced SR inventory levels and we expect the incremental investments in improvements at our Malaysian SR plant to improve yields and reduce our production costs."

"While near-term pressure may impede our ability to deliver growth in our TiO2 business during the next several quarters, we expect continued growth in our specialty alumina and other product categories during 2013. Our strategic focus remains on product innovation and continued reduction in our production costs with an objective to deliver on our targeted growth of 15% to 20% over the next three to five years" concluded Dr. Karasch.
