Corvus Gold Completes Key Infrastructure Milestones for Proposed North Bullfrog Development Plan

February 5, 2014


  • Key infrastructure elements in place (water, power and highway access)
  • Signed MOU with US Bureau of Land Management (Primary permitting agency) to define baseline characterization requirements for a mining plan of operations
  • Regulatory Agencies reviewing baseline characterization plans for hydrology, rock geochemistry and biology
  • Water quality sampling wells installed and operational
  • Metrological station completes 17 months of data collection
  • Advanced metallurgical optimization studies underway for Yellowjacket deposit and metallurgical characterization of low-grade deposit complete

Vancouver, B.C†Corvus Gold Inc. (“Corvus” or the “Company”) - (TSX: KOR, OTCQX: CORVF) provides the following update on key infrastructure components for the potential development of its 100% owned North Bullfrog project:


In December 2013, the Company completed the purchase of a 440 acre fee simple parcel of land located about 30 miles north of the North Bullfrog project area which carries with it 1,600 acre-feet of irrigation water rights within the Sarcobatus Flats water basin. Cost of the land was USD 1,000,000. This water right is significant because it provides all water presently anticipated to be required under the conceptual North Bullfrog mine plan.  The first phase of the hydrologic characterization program was completed during the 2013 drill program which successfully identified a potential water production well site in the Sarcobatus Flats (Nevada State Water Basin 146) within the northwest portion of the North Bullfrog Property.  The test well, NB-WW-10, penetrated over 300 metres of alluvial material with a static water level beginning at a depth of 55 metres and sustained air lift water production in excess of 100 gpm for several hours.  The Company has begun to register the purchase of the water rights with the Nevada State Engineer (“NSE”), and will begin to make application to the NSE to move the production point to North Bullfrog, and change the application to mining.


PQ core materials drilled in 2013 have been used to develop composites for metallurgical testing of quartz vein and stockwork mineralized material from the Yellowjacket area. Assaying of the core has been completed and construction of a group of five composite samples has begun. Additional cyanide bottle roll testing is currently underway at particle sizes of 80% passing -0.075 mm, -1.7 mm, -6.3 mm and -19 mm, and initial results are expected by late February 2014. Column leach tests will be conducted for 80% passing -6.3 mm and -19 mm particle sizes and are projected to begin in early February 2014. In addition, advanced metallurgical testing is being conducted on the potential benefits of milling the higher grade Yellowjacket material as this potential resource appears to have significant growth potential.

Vat leaching, Run of Mine type tests are also underway on Sierra Blanca mineralized material at nominal sizes of 100 mm, 150 mm, and 250 mm. In addition, the Company is initiating preliminary tests on higher grade sulfide material at depth which could represent a future resource potential.


The upgrade of the main power line, located along Highway 95 along the east side of the North Bullfrog Property, by Valley Electric Association is nearly complete.  The upgraded capacity of the line exceeds the current projected requirements of the North Bullfrog Project. The Company contributed USD 28,500 for the line upgrade.


Nevada Highway 95, connecting Las Vegas and Reno, passes North Bullfrog approximately 1 mile to the east, and received extensive maintenance upgrade during the summer of 2013.  The highway has been re-surfaced between Las Vegas and a point to the north of the North Bullfrog Project, thereby providing for efficient road access to the site. The Company will be making application for the necessary rights-of-way for road traffic from the highway to the proposed mine facilities.

Carl Brechtel, Chief Operating Officer, stated: “The acquisition of water rights now completes all of the major infrastructure components necessary for the potential development of a mining operation at the North Bullfrog project. Â Having available water, power and road access located close to the conceptualized heap leach pad and pit will provide the framework for what we anticipate would be a low cost and efficient operation. Â Corvus anticipates completing an updated PEA before the end of Q1 2014.”

Baseline Characterization

In January 2014, Corvus Gold Nevada Inc. executed a Memorandum of Understanding (“MOU”) with the Tonopah Office of the US Bureau of Land Management (“BLM”) for definition of baseline characterization requirements and development of a mining plan of operations at the North Bullfrog Project. Characterization plans for hydro-geologic modeling studies, rock geochemical studies and biologic/wildlife studies have been developed and have been reviewed by BLM specialists. The Company is in the process of responding to comments and additional requirements received from the BLM with respect to such plans.

A total of seven additional hydrologic test wells were drilled during 2013 to facilitate water level monitoring and water quality sampling stations located around the North Bullfrog Project.  These wells have been equipped with down-hole sample pumps. A network of nine surface springs is also being sampled in the greater area around the project site to ensure completeness in regional characterization.

A meteorological station was constructed during August 2012, and has now accumulated 17 months of continuous data.

Rock geochemistry characterization work has been underway since 2012, with both Acid-Base accounting static testing and Humidity Cell Testing data collected for the initially proposed pre-Yellowjacket high-grade discovery mining plan. Initial data have formed the basis of the geochemistry characterization plan document, which is now being updated to reflect the addition of the newly defined Yellowjacket deposit to the updated proposed mining plan.
