Mackay & Schnellmann

Mackay & Schnellmann Pty Limited has considerable expertise in Geographical Information Systems and their application to mineral exploration and prospectivity analysis. Computing services include image processing of Landsat, radar, airborne MSS and geophysical data optionally followed by a specialist prospectivity analysis. Digital data compilation may include geological, geochemical, geophysical and cadastral information that is then managed by either Mackay & Schnellmann Pty Limited or the client. Software includes ER Mapper, ArcView, MapInfo, Spatial Analyst, GenGIS and Micromine. The company specialises in target definition from a blend of technological and geological expertise achieved by integrating remote sensing interpretations with traditional ground truthing.

Examples of recent GIS, data management and prospectivity analysis assignments are:

INDIA, 2001
Over a three year period, an interactive GIs database was designed for the compilation of exploration results covering the 5000 km2 Raipur Kimberlite Field. Digital layers include satellite imagery, geological and structural mapping, geomorphological regimes, geochemical and mineragraphic results and EM and magnetometry data. The database was managed during ongoing exploration and subsequently provided to the client for future exploration activities. Training of the client's personnel in both GIS and data management was completed.

WESTERN AUSTRALIA, 2000
Twenty five target areas for future diamond exploration in the Ellendale area were identified for a Western Australian explorer. The new targets were developed by integrating results from structural, geomorphological and geological interpretations using Landsat TM satellite imagery with airborne EM and magnetic data and the results of previous exploration. The study identified both primary and alluvial diamond targets and demonstrated considerable scope for future exploration.

WESTERN AUSTRALIA, 2000
A leading mining software company approached us to extend their current capabilities to include GIS software. The project involved rewriting and updating existing manuals for training courses and the delivery of such courses specifically for ArcView and GenGIS software.

LIBERIA, 1999
Landsat TM interpretations were carried out on behalf of European clients in two successive years over the Lofa River region to identify areas prospective for alluvial diamonds.

ANGOLA, 1997
A remote sensing study using SPOT imagery was undertaken to analyse the influence on alluvial diamond occurrences of the evolution of drainage channels within a major river system.

Additional examples of professional assignments carried out by Mackay and Schnellmann Pty Limited that have involved GIS, data management and prospectivity analysis related activities will be found on the other Expertise pages as well as on the Commodities pages of this website.
