Earth Probe - In 2009, Caracle Creek partnered with Geoserve to introduce a new IP/Resistivity technology to the industry.
Earth Probe is a sophisticated modern means to collect highly detailed and deeper IP and resistivity information. The new EarthProbe high resolution resistivity and induced polarization (DCIP) system is challenging the way geophysical surveys have been done by integrating surface, borehole, and borehole-to-borehole subsurface imaging into one convenient system. Through initial funding by CAMIRO and development at University of Toronto, EarthProbe has proven to be an effective tool for both mineral exploration and engineering applications.
Traditional IP surveys have historically compromised target size, horizontal resolution, and depth of investigation to accommodate for logistical survey limitations. EarthProbe high-resolution DCIP surface surveys overcome all of the traditional difficulties by deploying tightly spaced electrodes (5 m spacing) to a centralized data acquisition system that enables arbitrary selection of current and potential electrodes through relays. Rapid data acquisition and signal processing techniques allow for efficient use of conventional and non-conventional arrays and the removal of natural and cultural noise. The result is a high resolution DCIP system able to delineate both large resistivity/chargeability anomalies and narrow structural features down to depths of approximately 240 m. The system is particularly relevant for narrow vein gold exploration where traditional DCIP systems have failed due to depth limitations and the lack of lateral resolution.
The EarthProbe Team provides:
- Borehole characterization studies
- Off hole detection to 100m
- Imaging between holes
- Surface surveys to greater than 250 metres
Rapid data acquisition and signal processing
Tightly spaced electrodes are interfaced to a centralized data acquisition system enabling tailored selection of conventional and non-conventional arrays through relays. Rapid data acquisition and signal processing techniques allow for effective removal of natural and cultural noise. The result is a survey able to delineate both large resistivity/chargeability anomalies and narrow structural features at both shallow and mid-earth depths.
Benefits of the Earth Probe
- Characterize - characterizes bulk resistivity/chargeability.
- Detect - locates off-hole conductive/chargeable zones.
- See details - achieves higher lateral resolution and depth penetration than traditional IP.
- Delineate - delineates both large targets and narrow vein alteration zones.
- Drill with confidence - maps continuity of conductive/chargeable zones between boreholes.
Surface IP Surveying
- High lateral resolution, deeper vertical resolution than traditional IP.
Vertical Resistivity and Chargeability Profiling
Resistivity/chargeability characterization, identify in-hole and off-hole targets
By using a single borehole, in-hole vertical resistivity/chargeability profiling can be rapidly undertaken to depths up to 400 m to characterize bulk and in-situ resistivity/chargeability of host rocks, which can assist with the calibration/interpretation of other resistivity, IP and EM data sets. Further, the downhole electrodes can be rapidly configured to operate using standard “surface” arrays thus providing downhole pseudo-sections. The profiles collected assist to define the off-hole extent of intersected mineralization, and identify conductive/ chargeable features in the vicinity of the borehole that have been missed by the drillholes.
