In 2011, Imerys Minerals and Norsk Minerals merged their key production plants—Spruce Pines, North Carolina, and Drag, Norway—to form The Quartz Corp (TQC). This 50/50 joint venture, capitalising on the expertise of both companies, and Imerys’ access to the world's purest quartz deposit, has enabled The Quartz Corp to supply top quality High Purity Quartz to customers within a variety of industries. With offices in North America and Europe, as well as employees on the ground in China, we are able to support a network of global customers, many of whom are key players within their respective industries. Our vision is to become a major and sustainable player in the High Purity Quartz market by supplying High Purity Quartz materials to all relevant market segments. Our High Purity Quartz is unique, sourced from Spruce Pines, the only mine on earth with quartz pure enough to produce the crucibles needed to manufacture semiconductor ingots. Taking this unique product from Spruce Pines, combining this with our other pure quartz source in Drag, Norway, treating it in our plant in Drag, allows us to produce both standardised and specialised products for our customers, based on their needs. Working closely with customers and strategic partners, we strive to be the highest quality and most reliable producer of High Purity Quartz materials, providing solutions to our customers'​ evolving needs.

Blackhawk Mining, LLC (“Blackhawk”) is a privately-held mining company based out of Lexington, Kentucky. Blackhawk’s primary focus is the mining, marketing, and sale of metallurgical coal—a globally scarce commodity and indispensable element in the production of steel. The company was founded in 2010 with the acquisition of a single mining complex in Floyd County, Kentucky. In its first full year of operation, Blackhawk produced just over a million tons of coal. Since that time, and in spite of recent volatility in the coal industry, Blackhawk has surmounted significant structural and economic pressures to cement itself as an industry leader that is well-positioned to thrive in shifting market cycles. Blackhawk has become a premier supplier of high vol. metallurgical and CAPP thermal coals by consistently and continually expanding its reach through the strategic acquisition of premium assets from distressed sellers. In 2017, Blackhawk is expected to be the largest metallurgical coal producer in the United States. Presently, the company operates nine mining complexes throughout Kentucky and West Virginia that employ 2,600 people and service customers across four continents.
