Corvus Gold Inc. Expands North Bullfrog’s Sierra Blanca Deposit to the West and North

The WSB target area (West Sierra Blanca) is a large pediment covered area over a kilometre long and half a kilometre wide, with assays pending on 7 additional completed holes. Mineralization in this area is dominantly oxide with the oxide-sulfide boundary variable from 100 to 200 metres in depth similar to most areas at North Bullfrog. The Company plans to complete an additional 20 holes at the WSB target in this phase.

New Land Package

Corvus recently staked a large block of land (Gap Claims, Figure 2) on the southern extension of the new Kinross Gold Corp. land package in the southwestern part of the District (Figure 1 & 2). This area contains a large regional structural zone called the Ransome Fault that hosts the historic, high-grade, original Bullfrog gold deposit. Corvus believes the target environment is analogous to the Mother Lode setting with mineralization focused at the volcanic-basement contact which is largely untested in this area.

The new claims are also adjacent to the west side of the large AngloGold Ashanti Ltd., Rhyolite project and contains the western extension of their large, high level alteration system that Corvus believes has similarities to the Silicon area to the east side of the District. Corvus is currently conducting an in-depth surface exploration program on the target in preparation for scout drilling later this fall.

Corvus also tested other early stage targets at North Bullfrog with three returning positive results that warrant follow-up (Table 1). The first two holes ever drilled in the Cat Hill West target returned a shallow intercept (15.2m @ 0.58 g/t gold) with abundant surrounding low-grade. In addition, results from testing the northern extension of the YellowJacket vein deposit returned encouraging results with 24.4 metres of 1.21 g/t gold surrounded by zones of low-grade.

Jeff Pontius, President and CEO of Corvus, said, “The initial results from our new discovery program at North Bullfrog have been encouraging with significant mineralization in a number of areas and several broad zones of low-grade gold. We believe that the newly identified mineralization at WSB and Cat Hill could hold the key for expansion of YellowJacket type mineralization in the North Bullfrog area. These well-mineralized, structural zones have never been explored due to the thin post-mineral cover and offer an opportunity to discover additional YellowJacket type systems within North Bullfrog. Additionally, we believe the staking of our new Ransome target is exciting as it is strategically placed between both the Kinross Gold and AngloGold Ashanti properties with potential to be an attractive high-grade target.”

(Reported intercepts are not true widths as there is currently insufficient data to calculate true orientation in space. Mineralized intervals are calculated using a 0.3 g/t cutoff unless otherwise indicated below)

West Sierra Blanca

The initial holes in the WSB target are testing structural zones on the west side of the main deposit that are currently in or marginal to areas of untested waste material. The positive results from hole NB19-456 (16.8m @ 1.37 g/t Au) is from a north trending structural zone. This zone is characterized by disseminated and fine stockwork quartz and intrusive dikes similar in texture to those at YellowJacket and Mother Lode and looks to be extending to depth from an oxide horizon into a deeper sulfide system. Corvus believes the alteration and large areas of surrounding low-grade gold are similar to the high-grade system at YellowJacket that lies a kilometre to the east. The current target area is about one kilometre long, a half a kilometre wide and covered with a thin veneer of pediment (<10m). Ongoing drilling in this target area has been able to define and extend several of these, dike filled, structural zones as we continue with an aggressive follow-up program.

North YellowJacket

Hole NB19-455 tested the potential for expanding the YellowJacket vein system to the north. The positive results (24.4m @ 1.21 g/t Au) indicate the system is more north-south than previously thought and a follow-up program is planned to continue working on defining the full extent of the system. In addition, Corvus has designed a deep test of the YellowJacket gold system to assess repeated vein zones at depth which are common in this type of epithermal systems.

West Cat Hill

The West Cat Hill target is a large untested alteration system to the west of the District scale Road Fault. Hole NB19-446 intersected a broad stockwork quartz zone that was well mineralized (15.2m @ 0.58 g/t) and is typical of the upper parts of YellowJacket or Bullfrog type high-grade vein systems. The alteration system in this area is large and the mineralization in hole NB19-446 will be followed up with additional drilling at depth and along strike.

South Jolly Jane

Mineral resource extension drill testing of the Jolly Jane deposit to the south produced encouraging results with 36.6m of 0.34 g/t gold in hole NB19-448. This mineralization indicated the favorable Jolly Jane mineralized horizon extends to the south, offering future mineral resource expansion potential. In addition, hole NB19-449 ended in lower plate carbonates that were altered to jasperoid and had 9.2m of 0.19 g/t gold which Corvus believes could be a distal indicator of a sediment hosted system in the lower plate carbonates that underlie most of the North Bullfrog gold systems (similar to our Mother Lode deposit). Follow-up exploration will be planned for this area in the future.

Other Results

Results from the Jasperoid and West Air Track targets returned no significant results and no further work is planned on these areas during this phase of North Bullfrog exploration.
