Exhibit 99.1

GREENHUNTER RESOURCES ENTERS INTO AN

AGREEMENT FOR A $16 MILLION SENIOR SECURED TERM LOAN

Improved Liquidity to Fully Fund

2015 Capex Budget

GRAPEVINE, TEXAS, April 15, 2015—GreenHunter Resources, Inc. (NYSE MKT: GRH and GRH.PC), a diversified water resource, waste management, environmental services, and hydrocarbon marketing company specializing in the unconventional oil and natural gas shale resource plays, announced today that it has entered into an agreement for a senior secured term note financing of up to $16 million. Use of proceeds from the senior secured financing includes development of two new barge terminals located at GreenHunter’s New Matamoras and Mills Hunter existing facilities, four new Salt Water Disposal (SWD) wells at the company’s Mills Hunter facility, new state-of-the-art 407 trucks and for general corporate purposes.

The promissory notes bear a fixed annual interest percentage rate of nine (9) percent. The loan is payable over a 36 month term with interest only for the first 6 months. There are no forms of equity or warrants associated with this new term loan.

The senior secured term loan facility is structured in two tranches. The first tranche of loans will be in the principal amount of $13,000,000, subject to customary conditions, and, at the request of the Borrower and subject to the certain conditions, the second tranche of loans will be in a principal amount of up $3,000,000 and must occur within six months of the first closing. Northland Capital Markets acted as financial advisor to GreenHunter in connection with the transaction. Northland Capital Markets is the trade name for certain capital markets and investment banking services of Northland Securities, Inc., member FINRA/SIPC.

Gary C. Evans, Chairman and Interim CEO of GreenHunter Resources, Inc., said, “This new senior secured term loan facility is the type of financing we have been seeking for the past year. The improved liquidity will enable us to successfully execute our 2015 growth plan as we continue to approach total fluids management through the eyes of our valued customers, the E&P producers. From new SWD wells, to the development and completion of two new barge terminals to new and improved 407 trucks that will complement our existing in-house fleet, we will be able to better serve our clients, achieve greater operating efficiencies, and generate significantly increased cash flows from operations.”

Evans continued, “Despite the pullback in commodity prices, utilization rates at the Company’s SWD wells, as well as our trucking segment, continue to operate near full capacity. This is due to our balanced portfolio of produced and flow-back water which enables us to take an agnostic approach toward commodity prices. E&P operators, regardless of commodity prices, are required to manage total fluids movement and water disposal issues throughout the life of the well. The new loan proceeds will enable us to bring a number of new SWD wells online, serve clients with an added fleet of 407 trucks and begin to transition a portion of our transportation business to more efficient barging along the inner Ohio waterways.”
