CORVUS GOLD RECEIVES SULFIDE GOLD RECOVERY OF +90% USING AAO PROCESS AT THE NORTH BULLFROG PROJECT, NEVADA

Corvus Gold Inc. has provided the initial results from testing the atmospheric alkaline oxidation (AAO) method of oxidizing sulphide mineralization for low-cost cyanide gold extraction. Initial results of the AAO method for oxidizing sulphide material resulted in overall gold recoveries of approximately 93 per cent from milled material in the Sierra Blanca tuff (largest host unit), which is comparable with oxidized milled material recoveries in the current production plan. Results for the remaining three units are pending. Estimated additional operational cost to the mill material for the AAO process would raise the mill cut-off grade to approximately 0.65 gram per tonne.

The current North Bullfrog model has several areas below the current designed pit bottom that could be mined at above the projected sulphide mill cut-off grade. Further test work is continuing for both mill material as well as heap leach testing of lower grade material using the AAO process.

The AAO process has been extensively tested at the Hycroft project in northern Nevada where a pilot scale demonstration plant has been operated as well as test heap leach pads confirming the effectiveness of the processing technique. The AAO process has been included in the recent feasibility study done for the Hycroft project for commercial application.

Jeff Pontius, president and chief executive officer of Corvus, said: "The encouraging results from the application of the AAO process to North Bullfrog sulphide material could be a bonus to the project which already hosts a large oxide resource. In addition to the higher-grade, millable sulphide material, Corvus is conducting heap leach applications of AAO similar to the test work conducted at the Hycroft mine which if positive, could amplify its impact on the project. The current oxide deposit in our [preliminary economic assessment] study is underlain by an extensive sulphide zone that if amenable to this new low-cost method of extraction could change the way we approach exploration and expansion of the North Bullfrog project and district."

AAO sulphide oxidation process test work

The test work conducted by Hazen Research Inc. on North Bullfrog sulphide material is testing the four rock types which host nearly all of the known sulphide mineralization on the project (see attached table). The current test results are from the Sierra Blanca unit, which hosts about 50 per cent of the currently known sulphide mineralization on the North Bullfrog property. The test work conducted standard flotation concentration of the sulphide material which produced a high-quality concentrate that averaged 92 per cent gold in just 12 per cent of the original materials (9:1 concentration ratio) for the Sierra Blanca rock unit. That concentrate was then mixed with a sodium carbonate reagent (soda ash) in a reaction tank with oxygen introduced for a period of 72 hours at which point there was no sulphide sulphur remaining in the concentrate. That material was then leached using cyanide in a process similar to that which is proposed for North Bullfrog mill facility. As a control, an unoxidized (no AAO treatment) concentrate sample was cyanide leached which recovered only 12 per cent of the gold. Results for the remaining three units are pending.

The key additional cost elements in adding the AAO process to the existing North Bullfrog mill flow sheet are: a flotation circuit, a fine grinding circuit, AAO reaction tankage and an oxygen system. These added costs and reagents are currently projected to increase the mill cut-off grade for sulphide material to approximately 0.65 g/t Au. Corvus has identified a number of potential cost-saving opportunities for the system that will also be explored in the coming months. The current North Bullfrog project has a number of areas that host sulphide mineralization of sufficient grade to be processed using the AAO system, as well as a local source for soda ash, which is a key reagent. Corvus will report additional results for the other host units and heap leach tests as data become available.

Corvus Gold is also conducting column leach tests patterned after those used at the Hycroft project that were scaled up to two, successful 5,000-tonne test pads. These column tests use the highly reactive sodium carbonate material as an additive to the leach material in place of the standard lime addition. If the heap leach test work is successful, it would lower the cut-off grade required and expand the potential material that could be economically processed.

About the North Bullfrog project, Nevada

Corvus controls 100 per cent of its North Bullfrog project, which covers approximately 72 square kilometres in southern Nevada. The property package is made up of a number of private mineral leases of patented federal mining claims and 865 federal unpatented mining claims. The project has excellent infrastructure, being adjacent to a major highway and power corridor as well as a large water right.

The North Bullfrog project includes numerous prospective gold targets at various stages of exploration with four having National Instrument 43-101 mineral resources (Sierra Blanca, Jolly Jane, Mayflower and YellowJacket). The project contains a measured mineral resource of 3.86 million tonnes at an average grade of 2.55 g/t gold and 19.70 g/t silver, containing 316,500 ounces of gold and 2,445,000 ounces of silver, an indicated mineral resource of 1.81 million tonnes at an average grade of 1.53 g/t gold and 10.20 g/t silver, containing 89,100 ounces of gold and 593,600 ounces of silver, and an inferred resource of 1.48 million tonnes at an average grade of 0.83 g/t gold and 4.26 g/t silver, containing 39,500 ounces of gold and 202,700 ounces of silver for oxide mill processing. The mineral resource for the mill process was defined by Whittle optimization using all cost and recovery data and a break-even cut-off grade of 0.52 g/t gold. In addition, the project contains a measured mineral resource of 300,000 tonnes at an average grade of 0.25 g/t gold and 2.76 g/t silver, containing 2,400 ounces of gold and 26,600 ounces of silver, an indicated mineral resource of 22.86 million tonnes at an average grade of 0.30 g/t gold and 0.43 g/t silver, containing 220,500 ounces of gold and 316,100 ounces of silver, and an inferred mineral resource of 176.3 million tonnes at an average grade of 0.19 g/t gold and 0.67 g/t silver, containing 1,077,400 ounces of gold and 3,799,200 ounces of silver for oxide, heap leach processing. The mineral resource for heap leach processing was defined by Whittle optimization using all cost and recovery data and a break-even cut-off grade of 0.15 g/t.
