Kerr to Commence Drilling at Copperstone

TORONTO, ONTARIO--(Marketwired - April 21, 2015) - Kerr Mines Inc. ("Kerr" or the "Company") (TSX:KER) is pleased to report that drilling in and around the Copperstone gold deposit located in Western Arizona is set to commence. Initial drilling will primarily target the Lower Plate Zone located parallel to the main Copperstone zones that were previously mined by open pit and underground methods.

A number of widely spaced, high grade gold intersections were obtained within the Lower Plate by previous operators such as 0.29 oz/ton over 35 feet, including 0.65 oz/ton over 15 feet in drill hole #DCU-08. The Lower Plate Zone is located approximately 300 to 500 feet to the footwall of the Copperstone main zones and runs parallel to the open pit and current underground development. The goal of this phase of drilling will be to follow up on previous intersections and to extend the zone along strike and dip towards current underground access allowing for potential future development in conjunction with the main Copperstone zones.

"This drill program is significant as any success on the Lower Plate creates additional flexibility in the future development of Copperstone. Thoughtful planning and definition of the A through D Copperstone zones with the addition of the Lower Plate will be our near-term focus. The near-surface location and high grades of the Copperstone and Lower Plate zones bode well for future development," commented Greg Gibson, CEO.

The Company has not yet completed the work necessary to verify the past exploration results and since some of these results are historical in nature and some results predate National Instrument 43-101 ("NI 43-101") standards, these results should not be relied upon. In addition, a qualified person has not completed sufficient work to verify these historical results and the Company is not treating these results as current. The technical information in this news release has been prepared in accordance with the Canadian regulatory requirements set out in NI 43-101 and reviewed and approved by Dale Ginn, P.Geo., a "Qualified Person" as defined by NI 43-101 for this project.
