(TSX VENTURE:RK) (\"Rockhaven\") is pleased to announce an updated Mineral Resource estimate for its 100%-owned and road-accessible Klaza property, located in the Dawson Range Gold Belt of southern Yukon. The updated Mineral Resource estimate incorporates results from drilling in 2015 at the Klaza and BRX zones, including the newly modelled Eastern BRX Zone and a number of subsidiary veins associated with the main structures. The updated Mineral Resource was prepared by AMC Mining Consultants (Canada) Ltd. This new estimate comprises a total Inferred Mineral Resource of 9,421,000 tonnes grading 4.48 g/t gold, 89.02 g/t silver, 0.75% lead and 0.95% zinc, and contains 1,358,000 oz gold, 26,962,000 oz silver, 155,417,000 lbs lead and 197,891,000 lbs zinc. The Mineral Resource has a gold equivalent metal content of 1,793,000 oz at a gold equivalent grade of 5.92 g/t. Results of this Mineral Resource estimate are summarized below.
