HCLP Hi-Crush Partners LP Common Units Representing Limited Partner Interests

Hi-Crush Partners LP (NYSE: HCLP), or "Hi-Crush", today announced that it has entered into a new, long-term frac sand supply agreement for the in-basin purchase of Northern White frac sand to support CNX Resources Corporation (“CNX”) and their completions program in the Marcellus and Utica shales. In addition, CNX will utilize one FB silo system and related logistics with the option to expand based on demand.

“We are excited to begin our relationship with CNX and further expand the base of E&P customers that we serve,” said Robert E. Rasmus, Chairman and Chief Executive Officer of Hi-Crush. “Our agreement with CNX to supply both Northern White frac sand and related logistics services to their operations in the Marcellus and Utica shales further demonstrates the value of Hi-Crush’s integrated service offerings, and the continued demand for Northern White frac sand. We look forward to working with CNX to support their operations, and continuing to expand our operations in the Northeast through execution on our Mine. Move. Manage. operating strategy.”

“This is another example of CNX’s willingness to push the envelope and shift a traditional paradigm when we see an opportunity to do so,” commented CNX Chief Operating Officer Tim Dugan. “We have typically sourced sand directly through our frac vendor, but we saw an opportunity here with Hi-Crush to gain efficiencies and improve our operations through integrated sand and logistics services - and we took it. We’re excited about the partnership.”
