Corvus Gold Begins Initial 13,000 Metre Mother Lode Drilling Program

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 6, 2017) - Corvus Gold Inc. ("Corvus" or the "Company") - (TSX:KOR) (OTCQX:CORVF) announces it has started its Phase I, Mother Lode drill program which will utilize three drill rigs (two reverse circulation and one core). The initial program is scheduled for approximately 13,000 metres and is focused on confirmation of the existing 172-hole database and addressing priority I resource expansion exploration targets in four main zones of historic mineralization. The Phase I program is anticipated for completion in December with the Phase II drilling program scheduled to begin in January 2018. 

Primary Objectives of the Phase 1 program:

• Confirm and expand the existing 433,000-ounce, 1.6 g/t gold non-National Instrument 43-101 ("NI-43-101") estimate*. 
• Acquire representative material for metallurgical testing
• Define the key ore controls on the high-grade mineralization in the system

*The historic estimates for the Mother Lode property contained in this news release should not be relied upon. These estimates are not National Instrument 43-101 ("NI-43-101") compliant. While the Company considers these historical estimates to be relevant to investors as it may indicate the presence of mineralization, a qualified person for the Company has not done sufficient work to classify the historical estimates as current mineral resources as defined by NI 43-101 and the Company is not treating these historical estimates as a current mineral resource.

Jeff Pontius, President and CEO of Corvus said, "This is an exciting time for Corvus as we conduct the first modern drill program in over 30 years at our newly acquired Mother Lode property. Our analysis of the extensive historic database acquired with the property and its new geologic mapping and sampling results, has defined a large structural zone which has been intruded by mineralized dikes forming several excellent targets for high-grade gold mineralization. The Mother Lode gold system has potential for both high-grade epithermal deposits like Bullfrog type deposits as well as Carlin style sediment hosted gold deposits. We believe that Mother Lode system holds the potential for the discovery of a new gold system in Nevada."

Initial Target Areas to be Tested

The Mother Lode Phase I program will test four main target areas over the course of the next four months with a follow-up resource infill and expansion program planned to begin in January, 2018. The key Phase I program target areas are described below:

• Main Zone - The Main Zone target focused on the core area of the historic estimate which is centered around a large NNW structural zone which has been intruded by a mineralized porphyry dike system. This area has a series of gently, north dipping, tabular bodies immediately below and to the north of the historic open pit. The mineralization in this area is hosted by volcanic sediments and porphyry intrusives with many of the holes ending in +1 g/t gold mineralization. In addition, due to the shallow drilling, the main Fluorspar Canyon Fault was never drill tested in the Main Zone which is projected to have Roberts Mountain limestone below the fault. The Roberts Mountain limestone is an important ore host in north central Nevada where several million ounces of production has come from this unit.

• Western Extension - The Western Extension target area is characterized by a series of wide spaced drill intercepts, which suggests the tabular mineralized bodies of the Main Zone extend to the west. The Western target offers immediate resource expansion potential for the system. It is also possible that this area may have a parallel, N-S trending, structurally controlled high-grade, feeder zone in association with porphyry dikes.

Historic Western Extension Drill Hole Highlights*:

• Northern Extension - The Northern Extension target is defined by a few scattered historic holes which drilled deep enough to intersect the northern projection of the Main Zone. A key hole in this area is hole ML-338 which is approximately 200 metres north of the main historic resource area and intersected 73 metres of 2 g/t gold at the bottom of the hole. This vertical hole is on the projection of the key mineralizing porphyry dike trend and suggests the high-grade Main Zone gold system could expand to the north.

• FCF Zone - The FCF (Fluorspar Canyon Fault) Zone target is focused on the main regional E-W trending, north dipping, detachment related, structural zone. This structural feature extends for over 50 km and appears to be an important feature in localizing a number of gold deposits including the historic Bullfrog mine to the west (several million ounces of production and resource). The FCF Zone has been drill tested with a few wide spaced holes at Mother Lode and retuned broad zones of +1 g/t gold mineralization. This large structural zone hosts broad areas of gold mineralization within the fault and in the underlying limestone units. The FCF Zone is displaced or rotated in the area of the Mother Lode deposit where it is intersected by the major N-S trending, Mother Lode structural zone. This complex structural intersection has localized a series of porphyry intrusives which are mineralized and thought to be genetically connected to the mineralization along the FCF trend.
