Make accurate decisions at a lower cost
TruScan offers high-definition wet, dry, and scan-spot photos (to scale) of the retrieved rock core. This information can be quickly viewed by the geologist and aids in the logging and interpretation of the geology—more accurate conceptual geological models can be built while the drill is still on the borehole. Because the time to collect data is significantly reduced, exploration and mining companies can make accurate and timely decisions on where to drill next or to what depth, thus lowering the costs of collecting and analyzing data.
Unique, precise technology
TruScan uses a unique XRF technology to address textural variations in rock and site-specific calibrations to address the rock type specific matrix effect. To ensure more precise onsite readings, rock samples are sent first from the site to the lab for chemical analysis. Once received back, the resulting chemistry is used to calibrate TruScan’s XRF technology, which is performed by a qualified Boart Longyear geochemist prior to the unit being sent to the drill site.
Analyze a wide range of elements
TruScan is able to simultaneously analyze drill core for every element between sodium and uranium on the periodic table. This means you have an extensive range of elemental data to use onsite, sampling anything from a millimeter to a one-meter interval. There is significant value in this data density which exposes geological heterogeneities not seen when using traditional destructive analytical methods that provide sparse data points from homogenized lab samples over a specific core length. Same-day TruScan data can be used by the geologist to log core more accurately the first time, identify alteration zones, and determine where to sample and where not to sample for lab analysis. This leads to cost savings tied to less re-logging of drill core, getting the geological model right the first time while the drill is still on the hole, and reducing analytical costs through a more targeted approach to assay. Because of TruScan’s matrix-specific calibration process and ability to address textural variation in rock, all field trials to date have shown a strong correlation between TruScan results and lab assay results for a variety of geological settings and commodities.
No onsite specialist needed
Because it has been previously calibrated, TruScan does not require the operator to have knowledge of XRF analysis. TruScan can be operated by the drill crew, removing the need for additional staff on site. No additional staff onsite both minimizes the cost to deploy this technology and keeps onsite environmental health and safety (EHS) related risk low. In addition, this technology is designed to fit into the normal workflow of Boart Longyear drill crews so there is no decrease in drilling productivity.
The TruScan unit operates on 110v or 220v power. In its peak power demand, it requires less than 15 amps of current. The water requirements are approximately 20 liters for every 1000m of core. The trailer measures approximately 134 inches (340cm) long without the trailer hitch attachment (196 inches or 498cm with hitch) by 91 inches (231cm) wide (with roller beds in the closed position). An additional working area of about 4 feet (122cm) in width is required for loading and unloading of core boxes (core box storage not included). Flat level ground is required for operation of this device.
