U.S. Silica Holdings, Inc. (NYSE: SLCA) today announced an innovative alliance with BNSF Railway Company (BNSF) to build a new silica sand storage facility in San Antonio, TX, that will support the rapidly growing oil and gas extraction industry in the Eagle Ford shale. US Silica is the second largest domestic producer of commercial silica, a specialized mineral that is a critical input into the oil and gas proppants end market and various industrial and specialty products. BNSF Railway is one of North America's leading freight transportation companies operating on 32,000 route miles of track in 28 states and two Canadian provinces. Together, US Silica and BNSF will build a new 15,000-ton frac sand storage facility, which will be operational in early 2013. Bryan Shinn, US Silica’s Chief Executive Officer, said the company is “very excited to partner with BNSF to add a unit train frac sand storage facility in a prime Eagle Ford location. US Silica is committed to continuing to differentiate our offering by leveraging our scale and flexible supply chain to bring high quality products closer to the market.” “Working with US Silica to extend BNSF’s service into the Eagle Ford shale will create new opportunities for growth for the nation’s energy supply, for jobs and the economy,” said John Lanigan, BNSF executive vice president and chief marketing officer. US Silica anticipates the company will make three to four shipments per month of approximately 10,000 tons of frac sand on 100 car unit BNSF trains from its Ottawa, IL sand mine to meet the industry’s need for proppant. The shipments will include three different grades of dry sand, as well as resin coated proppants from US Silica’s new facility in Rochelle, IL, which is expected to be fully operational in the first quarter of 2013.
