8 December 2017

Aston Bay Holdings Ltd. is pleased to announce an initial inferred mineral resource estimate for its Seal zinc deposit located on its 100% owned, >414,00 hectare Aston Bay property, Somerset Island, Nunavut. The deposit, which is located ~200m from tidewater, is a stratabound body hosted in sandy dolostone and sandstone within a thick section of Paleozoic dolostones, and was discovered by Cominco Ltd (now Teck Ltd.) in the mid 1990s. The Aston Bay property also hosts the high-grade Storm copper prospects approximately 30 km east of Seal. The Seal zinc deposit is estimated to contain 1.006 million tonnes at a grade of 10.24% zinc and 46.5 grams per tonne silver, using a cutoff of 4.0% zinc equivalent. The estimate is based on diamond drilling conducted by Cominco in 1995-96 and Noranda in 2001, and was prepared by P&E Mining Consultants Inc. in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects. Known mineralization has a thickness of up to 20 m, and extends for over 400m along strike and 50 to 100m down-dip, and is partially fault-bound.
