Corvus Gold Expands Exploration Focus for New Mother Lode and Bullfrog Type Deposits with Belt-Wide Geophysical Survey
VANCOUVER, May 19, 2020 - Corvus Gold Inc. (“Corvus” or the “Company”) - (TSX: KOR, OTCQX: CORVF) announces that it has initiated geophysical surveys throughout the Mother Lode trend to integrate district scale data into its belt-wide exploration models (Figure 1). The greatly expanded survey as well as other ongoing regional studies and data compilations are designed to effectively and efficiently unlock the significant potential for new discoveries across the belt and throughout the greater Bullfrog Gold District.
In addition, Corvus has expanded its land position east of AngloGold Ashanti’s new Silicon discovery and north of a new large claim block recently staked by Kinross Gold (Figure 1). Activity in the belt and the Bullfrog District in general is rapidly expanding with new claim staking and new Plan of Operations permits filed for large drilling programs by Corvus, AngloGold Ashanti and Coeur Mining.

Potential for New Intrusion Related, Sediment Hosted and Epithermal Gold Discoveries Throughout the Bullfrog Gold District
Over the past two years, Corvus has successfully defined a new, large and potentially expanding gold deposit at its Mother Lode property. This new discovery has recently shown a strong intrusion/structural relationship at depth which is directly related to the overlying sediment hosted gold deposit. As a result, Corvus believes that the Mother Lode belt may host other related distal higher level epithermal, vein/stockwork mineralization. The large new Central Intrusive Zone (CIZ) discovery below the Mother Lode deposit is in a unique and underexplored geologic setting within a major, past producing gold mining district. Recent other new discoveries in the district by AngloGold Ashanti to the north and Coeur Mining to the west of Mother Lode may provide further evidence of the potential within this new gold exploration target. Corvus has projected favorable alteration and host rocks across the Mother Lode belt with potential for other intrusion/hydrothermal related sediment hosted and vein/stockwork gold deposits in areas controlled by the Company.
Corvus Gold’s planned AMT (Audio-frequency Magnetotellurics) geophysical survey is designed to identify critical rock packages and structural features that are favorable for Mother Lode and Bullfrog type gold mineralization as well as highlighting disruptive intrusive activity that could be the thermal driver of the systems. In addition, surface exploration on Corvus claims staked east and south of AngloGold’s Silicon discovery has defined new target areas for follow-up exploration and possible future drill testing.
Jeffrey Pontius, President and CEO of Corvus, said, “The ongoing exploration work by Corvus in the Mother Lode Belt is providing the Company the ability to define and test new Mother Lode and Bullfrog type gold occurrences in one of the key gold belts of the Bullfrog Mining District. New exploration results from deeper in the Mother Lode system continue to show potential for expanding the deposit as well as providing critical data for potentially defining new occurrences. As Mother Lode grows and new discoveries are made across the belt and the District, we expect continued strong interest in this region from a number of producers looking for open-pit gold projects in a safe and well-established mining jurisdiction. Corvus’ aggressive exploration programs and currently defined deposits at both the North Bullfrog and Mother Lode have been leading the effort to re-establish the Bullfrog Mining District as a potential new, major gold production center in Nevada. As multi-company, District-wide exploration activity continues its rapid acceleration this goal is being achieved as we speak.”
