CALGARY, ALBERTA, June 1, 2015 - NXT Energy Solutions Inc. (“NXT Energy” or the “Company”) (TSX-V:SFD; OTCQB:NSFDF) advises that its interim financial and operating results for the three month quarter ended March 31, 2015 (“Q1-2015”) have been filed in Canada on SEDAR at www.sedar.com, and will be available in the USA on EDGAR at www.sec.gov/edgar, and on NXT’s website at http://www.nxtenergy.com/.  All selected and referenced financial information noted below should be read in conjunction with the Company’s unaudited interim consolidated financial statements and related management’s discussion and analysis (“MD&A”) for the Q1-2015 period.

A condensed summary from the Q1-2015 interim consolidated financial statements, with comparative figures for the three month period ended March 31, 2014 (“Q1-2014”) is given below.

George Liszicasz, President and CEO of NXT, noted “the Q1-2014 period reflected the completion of a survey project in the USA for new client.  While we did not have revenue activity in Q1-2015, we are excited that this week we are mobilizing to our new SFD® survey project in Bolivia.  This project, which has a contract value exceeding US $13 million, is with another new client, the national oil company of Bolivia, and will be our largest project to date.  We have received an initial deposit valued at US $3.1 million (secured by a bank letter of guarantee issued to the client), which will be applied against the initial progress billing to be earned on the project.”
