US anthracite producer Blaschak Coal has added two new properties and about three-million tons of reserves to its Pennsylvania-based operations, giving Blaschak five active mine locations containing high-quality reserves. The company, engaged in the mining, processing and distributing anthracite coal in the state and one of the country's top anthracite producers - on Wednesday stated that the two new locations meant increased coal reserves for the company, additional capacity to produce run-of-mine coal at favourable mine ratios and operating costs, and critical flexibility to optimise production for quality assurance and production cost.
