OZEX' COMPEX™ METHOD FOR GEOCHEMICAL COMPOSITES
Why CompEx™?
Composition of samples is widely practiced in almost all forms of drilling, but not in soil sampling or auger drilling. Used historically to minimise costs and maximise ground coverage - and accredited with the Tropicana discovery - OZEX has developed its own method for accurately and precisely deploying surface geochem sample composition.
More and more explorers are turning to CompEx™ to boost their exploration productivity.
Appraisal of project area
Each project must be assessed to determine suitability for sample composition. OZEX's geologists will determine this by regolith analysis and a retrospective composition of historic geochem results from the project area (if available)
Planning of geochem sample location grid and generation of composite centroids
OZEX can plan your initial grid, and then use its proprietary software to generate sample composite centroids at your choice of interval (2,3,4 or 5) and assign all sample ID's. The data sheet is ready for import directly into your existing database.
Collection method
OZEX will use its own sieves - designed in-house - to collect the samples, with the primary sample being maintained and kept in storage, pending the results of the composite samples.
Sample Composition
Once the samples are back at OZEX's HQ in Perth, the samples are carefully composited to form an even split of the primary samples. The composites are delivered to the lab, with the primary samples retained for future reference. LabWest also offer this service, if required.
Lab Analysis
We recommend using LabWest's proprietary Ultrafine analysis technique, however, any reputable laboratory will suffice. Carl at Camp Oven Exploration can provide guidance on the best methods for your project area.
Post-processing
Once the results have been returned from the lab, Camp Oven Exploration's geochemists are experts in sample composition - having worked with OZEX to generate the methodology. Usually, about 15-20% of the primary samples are sent to the lab. The results of these easily supercede the composite values in the database.
