CORVUS GOLD DRILLS 96 METRES @ 1.35 G/T GOLD, EXTENDS MOTHER LODE DEPOSIT TO THE WEST, NORTHWEST AND AT DEPTH, COMMENCES PHASE 2, 10,000 METRE DRILL PROGRAM
Corvus Gold Inc. has received further assay results from 10 new drill holes from its 2017 phase 1 drill program at the Mother Lode project in southern Nevada. The latest results include northwest and deep in-pit drilling, as well as stepout drilling to the west highlighted by hole ML17-020, which returned 96.0 metres at 1.35 grams per tonne gold and 1.24 g/t silver.Results continue to expand high-grade zones both laterally and at depth, which is potentially increasing the overall size and grade of the Mother Lode deposit.
The phase 1 drill program, which ended Dec. 16, 2017, completed 12,829 metres of drilling, representing 42 holes, 25 of which have now been reported. Phase 2 of the exploration drill program has commenced and is scheduled to drill 10,000 metres, focused on further expanding the deposit to the west, north and at depth.
Western extension
Holes ML17-018 through ML17-022 successfully demonstrate the continued grade and thickness of the shallow-dipping sediment-hosted deposit to the west.The new holes have drilled deeper in the system and appear to have intersected a new zone of mineralization below the currently targeted deposit. This is illustrated by hole ML17-020, which ended in 7.62 m at 3.46 g/t gold and 9.98 g/t silver within 27.4 m at 1.31 g/t gold and 3.9 g/t silver.Most of the new deeper holes ended in mineralization that is currently believed to be related at depth.Deeper drilling will be required to evaluate the potential of this new zone and will be conducted in the 2018 exploration program.
Northwestern expansion
Drill hole ML17-017 (35.1 m at 1.97 g/t gold) from the northwestern extension of the deposit, extends mineralization intercepted in hole ML17-003 and historic hole ML-338 (56.6 m at 1.35 g/t gold and 73.2 m at 2.05 g/t gold) to the west.Hole ML17-017, similar to ML-17-003 and historic hole ML-338 was not completed to its intended target depth, as they were lost due to poor rock conditions. The company completed two additional holes to the north of hole ML-338 during the phase 1 drill program with assays pending.These two new northern stepout holes were completed to the intended target depth and should provide insight into the expansion potential of this zone of mineralization.
In-pit depth expansion
Drill holes ML17-016 and ML17-023 through ML17-025 were drilled under the historic Mother Lode pit and are designed to verify and potentially expand the historic mineral resource estimate.The intercepts in these holes have matched well with the historic resource which is generally thinner and lower grade on the southern end of the deposit.Significantly, it appears drilling has intersected a new zone of mineralization at depth below the historic resource as illustrated by hole ML17-025 (13.7 m at 1.41 g/t gold) and hole ML17-016 (9.1 m at 0.98 g/t gold and 12.2 m at 0.96 g/t gold).Prior historical drilling primarily used vertical drill holes to a nominal depth of about 500 feet (150 m), with many holes ending in mineralization.
Jeff Pontius, president and chief executive officer of Corvus, stated: "As we continue to receive results from the Mother Lode deposit, the continuity of this new Nevada gold discovery is exciting with not one drill hole missing mineralization to date. The thickness, high grade and extent of the deposit improves with each round of results.The start of our expanded 2018 phase 2 drill program is exciting as we continue to march the deposit to the north and west as well as assess the depth extent of the system.Mother Lode is exceeding our expectations and developing into a major new Nevada gold discovery."
