Footprint of Surface Copper Mineralization Extended

Vancouver, British Columbia – September 10, 2014 – Aston Bay Holdings Ltd. (TSX-V: BAY) (“Aston Bay” or the “Company”) is pleased to announce that it has completed a joint summer exploration program at its Storm Project (“Storm”) in conjunction with a wholly-owned subsidiary of Antofagasta plc (“Antofagasta”). Outcomes from the program include new discoveries of copper-bearing frost heaved subcrop and float that increase the distance over which copper mineralization has been found at surface on the Project.

“We are very pleased to have had Antofagasta contribute technically to this year’s exploration program. The discoveries made are very exciting,” commented Benjamin Cox, Chief Executive Officer of Aston Bay. “The presence of copper-bearing subcrop and float in new areas reaffirms our belief that mineralization on the property may be more extensive than what has been defined to date by drilling.”

The joint exploration program was conducted over a three-week period by technical professionals from Aston Bay, Antofagasta and consulting company APEX Geoscience Ltd. Work completed at Storm included geological mapping in the vicinity of the known mineralization as well as prospecting and soil sampling in areas where little or no mineralization had been previously identified.

Targeting for the prospecting and soil sampling was driven by results from the Versatile Time Domain Electromagnetic (VTEM) survey conducted in 2011 and previous soil sampling programs. Copper-bearing minerals, including malachite and chalcocite, were discovered in frost heaved subcrop and float in several areas where no previous drilling or surface sampling had been conducted. Samples of the copper-bearing material were collected for assay and results will be released once obtained.
