Corvus Gold Expands Mother Lode Deposit to the East, West and at Depth Below Pit Bottom with Thick Oxide Mineralization to Depth
February 21, 2019
- ML18-090 & 100: 38m @ 2.58 g/t gold & 7.6m @ 3.61 g/t gold, below pit & east
- ML18-102 & 103: 32m @ 2.1 g/t gold & 22.9m @ 2.24 g/t gold, west, down dip FCF
Vancouver, B.C… Corvus Gold Inc. (“Corvus” or the “Company”) - (TSX: KOR, OTCQX: CORVF) announces it has received results from eight holes targeting the eastern, western and below pit bottom resource expansion potential at the Mother Lode deposit in Nevada (Table 1). Results continue to show high potential for expanding the deposit both to the west and east as well as at depth. In addition, many of the holes have ended in mineralization and have thickening oxide zones at depth (Figure 1). Resource expansion drilling at Mother Lode is ongoing with 15,000 metres planned during the current phase.
Below Pit Bottom
Gold mineralization in hole ML18-090 (38.1m @ 2.58 g/t Au) is immediately below and east of the old pit bottom, extending mineralization to the east of the initial resource (east of ML17-024 with 15.2m @ 2.76 g/t Au). Hole ML18-091 also intercepted two zones of oxide mineralization (9.14m @ 1.08 g/t Au & 6.1m @ 1.13 g/t Au) below and to the east of the pit (east of ML17-023 with 7.6m @ 2.69 g/t Au). Hole ML18-099 returned an encouraging intercept (41.2m @ 1.02 g/t Au) approximately 150 metres east of the old pit confirming the extension of thick good grade mineralization and the favorable host rock horizon. These new holes support continued exploration to the east of the main Mother Lode deposit where additional grid drilling will take place this spring.
The western extension of the deposit has been tested with two additional holes which have returned positive results from the Fluorspar Canyon Fault (FCF) Zone (ML18-102 with 32m @ 2.10 g/t Au and ML18-103 with 22.9m @ 2.24 g/t Au). These results show increasing grade with depth and continue to support the deep target along the FCF feeder structure and the potential for the down dropped western half of the Mother Lode deposit. This deep target is now over 500m in length and remains open along strike and at depth. Corvus is planning core drilling in the near future to test the deep potential of the Western Zone.
Gold mineralization in hole ML18-089 (30.5m @ 1.30 g/t Au), ML18-100 (7.6m @ 3.61 g/t Au) and ML18-101 show eastern expansion potential in the main part of the deposit and south toward the old pit. Historical drilling in this area was vertical and shallow and not deep enough to reach the projected gold deposit. In addition, follow-up drilling is planned to the north of hole ML18-101 in the NE target area which had a past hole ML18-049 (NR18-07, Mar. 22, 2018) that intersected a northeast trending high-grade zone with 7.6m at 21.77 g/t gold.
Jeff Pontius, President and CEO of Corvus, said, “The eastern expansion of the Pit and Main Zone is further confirmed with these latest results that open up a large new area to expand our existing deposit. Additionally, intercepts testing the down dip expansion of mineralization along the FCF continues to support the deposit growing at depth. Mother Lode is the key new cornerstone discovery in the Bullfrog Gold District, which is seeing expanding exploration activity from our neighbors, AngloGold and Coeur around our commanding, core land package. As we begin our expanded “New Discovery” exploration program at several priority targets on our large land package, we expect to continue to unlock the potential for this re-emerging, Nevada gold District.”
