 LINEAR E-SCAN and the "Cross-Line Strategy"

In 2014 we announced an updated and more powerful "LINEAR" E-SCAN 3D DC resistivity system that was initially designed for 3D mapping in conductive-target unconformity uranium settings such as in the Athabasca Basin.

This new strategy provides significant advantages over today's line-based survey techniques, and for a whole class of large, conductive target anomalies (Sedex, IOCG, nickel, geothermal alteration etc.), delivers a superior true 3D drill target result without the use of a distributed array survey system (like 3D E-SCAN or ORION 3D).

This faster, more direct true 3D target resolution comes at about the same cost as today's pole-pole and pole-dipole survey approaches. Starting from a single line of traverse data, it quickly locks on to observed conductive anomalies to deliver a drillable 3D result in a single field mobilization. No follow-up surveys,- drill-ready results in a few weeks.

This replaces the typical multi-season programs where initial results must first be computed and interpreted, then followed up by remobilization to the field for a second round of more detailed surveys.

The new technology is applied without preliminary line cutting, so a program can start within weeks of your decision to proceed,- as soon as site access and a camp can be set up.
