The resource and reserve estimation was completed by Gibraltar mine staff under the supervision of Scott Jones, P.Eng., Vice President, Engineering and a Qualified Person under National Instrument 43-101. Mr. Jones has verified the methods used to determine grade and tonnage in the geological model, reviewed the long range mine plan, and directed the economic evaluation. The reserve estimate used long term metal prices of US$2.75/lb for copper and US$11.00/lb for molybdenum and 0.85 C$/US$ foreign exchange. Mr. Jones has reviewed this release. A technical report is filed on www.sedar.com. Reserves and Resources were updated as of Dec 31/16.
