Gold Bull 3D Modeling of Soil Geophysics at Sandman

VANCOUVER, British Columbia, Jan. 24, 2022 (GLOBE NEWSWIRE) — Gold Bull Resources Corp. (TSX-V: GBRC) (“golden bull“or the”Society”) is pleased to announce that all CSAMT (ground geophysics) survey data has been received and incorporated into the drilling program which began last week on its wholly owned Sandman project (“Sandman” or the “ Project”) located in Humboldt County, Nevada, USA.


  • The 2022 ‘Phase 1’ drilling program at Sandman is underway
  • Phase 1 consists of 18 RC drill holes for approximately 4000m
  • A new exploration target model is being tested – exploration for high-grade “bonanza” gold sources
  • Recently Acquired Geophysical Data Helps in Borehole Prioritization and Selection

Cherie Leeden, CEO of Gold Bull, said:

“Exploration targets based on multiple lines of evidence – geophysics, geochemistry and geology – have a better chance of yielding successful drilling results. We are using geophysical data to project our interpretations of shallow drilling and surface geochemistry to greater depths, targeting a new gold discovery at Sandman. I’m proud of the new targets our tech team has generated, all of which are based on sound science, and I can’t wait to see the test results come in.

In this video link: https://goldbull.ca/media/#overlay-3271 Gold Bull project geologist Amy Hannink describes the relationships between interpreted structures and geophysical features (resistivity model). CSAMT resistivity models on east-west and north-south trending traverses in the Silica Ridge deposit and adjacent Windmill target area also support new targets derived from shallower drill data.


Two-dimensional resistivity models of CSAMT data from North Hill were received from DIAS Geophysical and the images were imported into Leapfrog for analysis. Hydrothermal feeder structures (faults) interpreted from the draft 3D gold grade model at depth on major breaks in a conductive layer (shaded in red) in the Triassic basement rocks under the mineral resource estimate of North Hill (MRE) (Figure 1). This observation supports our interpretation that faults associated with high-grade zones within the EMR are deeply rooted structures that may have acted as conduits for mineralizing fluids migrating from basement rocks into the Tertiary volcanic and sedimentary sequence. overlying. Our exploration model targets such faults near the drop in lithostatic pressure at the Triassic-Tertiary contact, where the loss of fluid volatiles is likely to cause a rapid reduction in gold solubility, depositing quality mineralization bonanza. Interpreted faults also align with the edges of resistive zones (shaded blue) near surface associated with adularia flooding of Tertiary rocks that accompanies gold mineralization, further supporting our geological interpretation.

The fault targeted by reconnaissance drilling west of North Hill coincides with changes in the dip of the conductive layers within the Tertiary and Triassic sequences. This hole will be the first drilled in our current program. A steeply dipping conductive zone that coincides with the demagnetization of a NNW-trending dyke (possible argillaceous alteration) is defined just west of this interpreted fault on the north CSAMT line. Our team will develop drill targets in this area based on offset geochemical sampling, current and historical drill data and CSAMT/magnetic/gravimetric geophysical data.

Next steps

  • Drilling has begun at Sandman and will continue over the next 2-3 months.
  • Laboratory assay results from the offset geochemical samples collected from the Windmill target area are awaited. We plan to add targets to the drill program resulting from the analysis of this data in conjunction with the CSAMT models.
  • Analysis and interpretation of CSAMT results from Windmill and Abel Knoll continues.
  • A staggered geochemical sampling program is planned for the Midway target area and west of North Hill as weather permits. The soil is currently still too wet for screening samples through classifiers.

About Sandman

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 explored intermittently since then. The Sandman Project comprises four known pit-constrained gold resources, consisting of 21.8 Mt at 0.7 g/t gold for 494,000 ounces of gold; comprising an indicated resource of 18,550 kt at 0.73 g/t gold for 433 koz of gold plus an inferred resource of 3,246 kt at 0.58 g/t gold for 61 koz of gold. Many of the resources remain open in multiple directions and the bulk of historic drilling has been done at depths below 100m. Sandman is conveniently located approximately 25-30 km northwest of the mining town of Winnemucca, Nevada.
