Vancouver, B.C… Corvus Gold Inc. (“Corvus” or the “Company”) - (TSX: KOR, OTCQX: CORVF) announces it has received initial results from the first two holes of its 2017 Phase I drilling program at its newly acquired Mother Lode project in southern Nevada (Table 1). The results have outlined two stacked, higher-grade zones within the deposit: An Upper Zone, hosted in intrusive and Tertiary sediments which is the primary initial target along the Mother Lode structural zone, and a newly discovered Lower Zone, approximately 40 metres below the Upper Zone within and below the Fluorspar Canyon Fault (FCF) hosted by intrusives and Paleozoic sedimentary rock. 

The new Lower Zone discovery has alteration and textures analogous to structurally controlled deposits that occur more commonly in the Carlin and Battle Mountain - Eureka trends of north central Nevada and represents an important new style of mineralization in the District.  Additionally, the results have confirmed location of the high-grade Mother Lode structural zone in the Upper Zone with 5.78 g/t gold over 11 metres in hole ML-17-001 and 4.86 g/t gold over 7.62 m in hole ML-17-004 which begins at about 100 metres from surface.  All of the mineralization discovered to date could be within open pit mining depths.  Ongoing drilling is targeting the northern extension of these thick zones of high-grade mineralization across an initial target area that is 300 metres wide and 500 metres long.

Jeff Pontius, President and CEO of Corvus states “These early results represent the first new exploration at the Mother Lode property in over 20 years (when gold was ~$300/oz), and have resulted in what we believe is a significant new discovery.  The results are not only confirming our initial Mother Lode, Upper Zone resource target but importantly have confirmed two new targets in the system, the high-grade, north trending Mother Lode Structural Zone and the lower plate, Paleozoic, sediment/intrusive hosted Lower Zone below the large Fluorspar Canyon Fault.  In addition, the high degree of oxidation in the lower plate section and abundant intrusive activity bode well for this new target environment.  Our ongoing drilling continues to hit broad zones of encouraging alteration and deep oxidation in this new Lower Zone of the deposit which we believe is outlining potential for additional zones below our current depth of drilling.  These recent results are opening the door for a new era of exploration in the Mother Lode area.”

Main Zone Mineralization

The mineralization intersected in the Upper Zone of the Mother Lode Main Target is hosted by Tertiary age sediments and intrusives.  These sediments which vary from fine grained mudstones to very coarse-grained conglomerates which are intruded by a series of dikes and sills.  The most significant structure discovered to date is the high-grade Mother Lode structural zone that trends north-south, dips steeply and forms the main axis of the deposit.   

The new Lower Zone discovery in the Main Target begins at a depth of approximately 150 metres below surface, is north plunging and has broad zones of consistent grade averaging approximately 1.5 - 2g/t gold (25.6m @ 2.17 g/t Au & 10.7m @ 1.54 g/t Au).  In this and other surrounding holes, the Lower Zone is hosted by the main FCF and in the lower plate Paleozoic sediments below.  It appears the mineralization is associated with abundant intrusive activity and associated decalcification, quartz veining/jasperoid silicification, strongly anomalous arsenic and deep oxidation as well as increasing silver values.  We believe this new and dynamic zone of hydrothermal alteration is encouraging for the development of a large system at depth.  Figure 2 shows some examples of the textures and alteration features of the upper Tertiary sedimentary units and the lower Paleozoic units that were intersected in core hole ML-17-002 (pending assays).

Results for hole ML-17-001 are only available to a depth of 219.55 metres with the bottom 87.32 metres pending and hole ML-17-004 was lost in the Lower Zone mineralization at a depth of 275.84 metres with the last interval in the hole returning 1.2 g/t gold in moderately altered spiderweb dolomite.  The Paleozoic rocks in the Lower Zone are part of the Roberts Mountain and Lone Mountain formations which are notable for hosting large gold deposits in north central Nevada.
