[{"type":"text","content":" 686,000 Indicated and 507,000 Inferred Gold Ounces VANCOUVER, British Columbia, June 21, 2018 (GLOBE NEWSWIRE) -- Rockhaven Resources Ltd. (TSX-V:RK) (“Rockhaven”) is pleased to announce updated Mineral Resource estimates for the high-grade Western BRX, Central BRX, Central Klaza, and Western Klaza zones at its 100%-owned and road accessible Klaza property, located in the Dawson Range Gold Belt of southern Yukon. The updated Mineral Resource estimates incorporate results from approximately 13,300 m of in-fill and expansion diamond drilling completed subsequent to the 2015 Mineral Resource estimate, and utilizes results from recent metallurgical test work to revise cut-off grades. Bulk tonnage low-grade mineralization in the Eastern Zones requires additional sampling, drilling and modeling, and is not included in these Mineral Resource estimates. Highlights from this news release include: Indicated Mineral Resources of 4.5 Mt containing 686,000 oz gold and 14,071,000 oz silver (grading 4.8 g/t gold and 98 g/t silver) or 907,000 oz gold equivalent (grading 6.3 g/t gold equivalent); Inferred Mineral Resources of 5.7 Mt containing 507,000 oz gold and 13,901,000 oz silver (grading 2.8 g/t gold and 76 g/t silver) or 725,000 oz gold equivalent (grading 3.9 g/t gold equivalent); and, Pit-constrained resources significantly increased in tonnes and grade compared to previous Mineral Resource estimates, including the Western BRX Zone with 759 kt at an average grade of 9.5 g/t gold, totaling 232,000 oz gold in the Indicated category.
