Lightstream Announces Closing of Previously Announced US $200 Million Secured Note Transaction and Production Update

Lightstream Resources Ltd. (the “Company” or “Lightstream”) (TSX:LTS) announces that we have completed the issuance of US$200 million in second lien notes (“Secured Notes”) for cash proceeds, as described in our July 2, 2015 press release. Proceeds will be used to reduce the outstanding borrowing under our credit facility, increasing the credit available to approximately Cdn$375 million. This increased liquidity provides financial flexibility to help withstand the current low-price commodity environment and gives us optionality to accelerate our drilling program should current economic conditions improve.

The Secured Notes have not been registered under the U.S. Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the U.S. Securities Act of 1933, as amended. This press release does not constitute an offer to sell or the solicitation of an offer to buy the Secured Notes, nor shall it constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale is unlawful.

PRODUCTION UPDATE

Our second quarter average production is estimated to be approximately 31,700 boepd (73% light oil and liquids) with first half production expected to average 33,400 boepd (74% light oil and liquids), in line with 2015 Guidance. Second quarter production was impacted by higher downtime associated with third party facility maintenance and spring break up. Production to date in July is estimated at 31,600 boepd.

We have seen encouraging results from the Falher gas play in our Cardium business unit, with two new liquids-rich gas wells on-stream in the quarter. We continue to evaluate further development drilling opportunities in this play to efficiently utilize our existing gas infrastructure.

Lightstream Resources Ltd. is an oil and gas exploration and production company focused on light oil in the Bakken and Cardium resource plays. We are committed to delivering industry leading operating netbacks, strong cash flows and consistent operating results through leading edge technology applied to a multi-year inventory of existing and emerging resource play opportunities. Our long-term strategy is to efficiently develop our assets and deliver an attractive dividend yield.
