SPECTREMPLUS as a High-Resolution Mapping Tool

Spectrem Air uses in-house data processing tools for 3D interpretation for accurate and reliable solid earth models. The below maps are from a Spectrem survey conducted in Namibia. The additional geological information available from the high-resolution AEM complements and enhances the traditional magnetic survey data and greatly improves exploration focus and targeting. 

Kimberlite Diamond Exploration

The Spectrem system has been successfully deployed in Africa, and North and South America on several diamond exploration projects.

Below, Spectrem easily detected several kimberlites around moderate conductive and thick cover. In many of the cases, the kimberlites displayed no obvious magnetic responses. 

Deep Detection of Targets

The Spectrem conductivity depth images displayed below show a conductive mineralised horizon being mapped to depths of 800m below the surface on a project in Brazil.

The borehole intersections indicate how accurately the target can be imaged. In addition, the change in conductivity response assisted the exploration team in targeting the prospective portion of the unit.

The 3D modelling and visual display assist in the understanding of geology.

Mapping Alluvial Channels

Spectrem Air’s system has been extensively used to map buried paleo-channels under conductive cover. This has been applied for buried diamond ferrous alluvial channels in South Africa, gold exploration in Africa, and geo-hydrology applications.

The product can also be used by geologists in understanding the regolith in the application of geochemistry.
