Gold Bull Resources Corp. (TSX-V: GBRC) (“Gold Bull” or the “Company”) is pleased to announce the commencement of a Geophysical Survey known as a Controlled Source Audio Magnetotellurics (CSAMT) within its 100% owned Sandman Project (“Sandman” or the “Project”) located in Humboldt County, Nevada, USA.


  • Ground Geophysics is proving an efficient technique for targeting mineralization undercover at Sandman
  • CSAMT can detect resistivity contrasts in the rocks below the surface which assists in defining and ranking high priority drill targets
  • Drill program planned to commence upon receipt of geophysical data – Q4 2021

Gold Bull Vice President – Exploration, David Johnson commented:


Areas prospective for gold within the Sandman project are extensively covered by wind-blown sand, concealing the geological indicators of mineralizing processes we might otherwise observe at surface.  We are drawing on the management team’s experience applying surface geochemistry and geophysics to covered terrains in Australia and Africa.  Orientation lag geochemical sampling over the Silica Ridge deposit provided encouragement that the technique can work in this setting, and analysis of the drill hole geochemical data from the Sandman deposits aids our understanding of pathfinder element associations.  CSAMT is a proven geophysical technique in epithermal gold exploration, particularly in Nevada.  We are integrating these new datasets with existing geological mapping, drilling, ground and airborne geophysical surveys, using our understanding of epithermal mineral systems and orientation over known deposits at Sandman.  Our current exploration model, discussed in the recent press release, is focused on the search for a world-class gold orebody. 


DIAS Geophysical of Saskatoon SK has commenced a Controlled Source Audio Magnetotelluric (CSAMT) survey (Figure 1) within the Sandman project, starting with a set of north-south oriented traverses covering a target zone east of the Silica Ridge deposit.  Reconnaissance surface geochemical sampling, using a method akin to lag sampling of desert deflation pavement material (refer to Carver, R., Chenoweth, L.M., Mazzucchelli, R., Oates, C.J., & Robbins, T. (1987). “Lag” — a geochemical sampling medium for arid regions. Journal of Geochemical Exploration, 28, 183-199), has provided encouraging initial results and infill sampling will be conducted prior to completion of the CSAMT survey.  CSAMT lines are also planned to cover the Abel Knoll deposit, to aid planning of drilling to follow up the intersection of 90 m (295 ft) at 0.6 g/t Au from 76.2 m (250 ft) in hole SA-0031 (refer to press release “Gold Bull reports significant new gold mineralization outside of current resource at Sandman including: 90m at 0.6 g/t Au” dated July 28, 2021).

Controlled Source Audio Magnetotelluric (CSAMT) surveying is an electromagnetic technique utilizing naturally occurring EM waves propagating in the waveguide formed by the magnetosphere and the Earth’s surface.  The EM waves are induced by regional and global lightning strikes and the interaction of the solar wind with the Earth’s magnetosphere.  Scattering of the EM waves by structures within the Earth produce perturbations in the time-varying electric and magnetic fields measured at surface, which can be numerically processed to yield images of those structures, which are in turn interpreted to determine the locations of faults that may have acted as conduits for mineralizing hydrothermal fluids.  For instance, the interface between the Triassic metasedimentary basement rocks and the overlying Tertiary volcanic and volcaniclastic sequence is the locus of a strong contrast in electrical resistivity, which is readily imaged using CSAMT.  Faults offsetting the Triassic-Tertiary contact are potential sites for gold mineralization.  Also, adularia alteration of the Tertiary rocks, often associated with gold mineralization, imparts high electrical resistivity, contrasting strongly with the argillic and propylitic altered, more electrically conductive country rocks.  Historic CSAMT data collected over the known deposits at Sandman provides useful orientation information on this geophysical technique.



Targets identified by interpreting the CSAMT geophysical data in conjunction with “lag” geochemical sampling data will be tested as part of the drilling programme planned for this winter.

In December 2020, Gold Bull purchased the Sandman Project from Newmont. Gold mineralization was first discovered at Sandman in 1987 by Kennecott and the project has been intermittently explored since then. There are four known pit constrained gold resources located within the Sandman Project, consisting of 21.8Mt @ 0.7g/t gold for 494,000 ounces of gold; comprising of an Indicated Resource of 18,550kt @ 0.73g/t gold for 433kozs of gold plus an Inferred Resource of 3,246kt @ 0.58g/t gold for 61kozs of gold. Several of the resources remain open in multiple directions and the bulk of the historical drilling has been conducted to a depth of less than 100m. Sandman is conveniently located circa 25-30 km northwest of the mining town of Winnemucca, Nevada.

Gold Bull’s mission is to grow into a US focused mid-tier gold development Company via rapidly discovering and acquiring additional ounces. The company’s exploration hub is based in Nevada, USA, a top-tier mineral district that contains significant historical production, existing mining infrastructure and an established mining culture. Gold Bull is led by a Board and Management team with a track record of exploration and acquisition success.

Gold Bull’s core asset is the Sandman Project, located in Nevada which has a 494,000 oz gold resource as per 2021 43-101 Resource Estimate. Sandman is located 23 km south of the Sleeper Mine and boasts excellent large-scale exploration potential. Drilling at Sandman is currently underway.

Gold Bull is driven by its core values and purpose which includes a commitment to safety, communication & transparency, environmental responsibility, community, and integrity.
