Rockhaven Resources Ltd. Sep. 26 reported the highest grade gold intercepts so far from drilling at its Klaza gold-silver property in southern Yukon.

The company published results from another 21 holes of a 96-hole, 15,922-meter drill program completed at Klaza this year.

Highlights from this drilling include 182 grams (5.85 ounces) per metric ton gold and 0.61 g/t silver over 0.61 meters, and 7 g/t gold and 7.12 g/t silver over 2.92 meters in hole 376; 4.18 g/t gold and 30.18 g/t silver over 6.94 meters in hole 370; 13.38 g/t gold and 397 g/t silver over 1.05 meters in hole 383; and 4.41 g/t gold and 23 g/t silver over 5.81 meters in hole 372.

The high-grade gold in hole 376 was intersected in the Central Klaza zone.

A 2016 preliminary economic assessment for Klaza envisions a 1,500-metric-ton-per-day process plant producing 630,000 oz gold, 11.35 million oz silver, 52.46 million lb zinc and 51.23 million lb lead over an initial 14-year mine life.

Since the completion of the PEA, Rockhaven has focused on metallurgical work, resource expansion and infill drilling to enhance the economics of mining Klaza.

Many of the intercepts from 49 holes reported to date from the 2017 program lie outside of the current mineral resource and mine plan.

In addition to resource upgrade and expansion, core from this year's program will be used for additional metallurgical testing, which is necessary to incorporate the Eastern BRX Zone into future economic studies.
