3D IP Survey Defines New Drill Targets
Gold Bull Resources Corp. (TSXV: GBRC) has completed a maiden 3D IP/resistivity geophysical survey at Sandman in Nevada and has received encouraging initial results. The IP survey focussed at the North Hill Prospect.
CEO Cherie Leeden said numerous gold exploration drill targets have been identified from a recent 3D IP survey
T”his IP data is a sensational end to Gold Bull’s first year. The 3D IP survey at our North Hill Target has illustrated that there is a strong correlation between the known mineralisation and this geophysical technique,” Leeden said.
“This means we will be using 3D IP in the future to define more drill targets. North Hill currently boasts a small gold resource however the source of that gold and the deeper (>150m) targets have never been drill tested, despite some highly encouraging oxide intercepts such as 7.75g/t over 3.96m from 7m from the surface.
“Our exploration team is looking forward to drilling these targets and others as soon as the permits have been transferred from Newmont’s name to ours. 2021 is going to be an exciting year for Gold Bull.”
Gold Bull has recognised that the zones of gold mineralisation roughly correspond to high resistivity values in the geophysical model. Rocks observed in drill cuttings and outcrop containing gold mineralisation at North Hill contain abundant hydrothermal silicate minerals, which are known to impart high electrical resistivity.
The company said this observation provides encouragement that we may target similar geophysical responses for drilling both within the current survey area and elsewhere in the Sandman property.
“Another interesting feature of the resistivity cross sections is the interpreted basement high located beneath the known gold mineralisation. The faults bounding this feature may have acted as conduits for mineralizing fluids that formed the North Hill deposit and are attractive targets for exploration drilling,” Leeden said.
The North Hill target has been characterised as an oxidized, low-sulphidation, epithermal gold occurrence that extends 550m long, 430m wide. Mineralization at North Hill is controlled by a combination of low-angle contacts between the various basalt flows and the interbedded fluvial conglomerates and tuffaceous rocks.
Previous drilling intersected oxide gold mineralisation stating at a depth of less than 60m and high-grade intercepts at North Hill.
