Geochemical Assay Analysis | Stewart Group Global

By: Stewart Group  05/12/2011

We offer a complete analytical service to the mining and mineral exploration industry through our network of dedicated laboratories.

“We Will Work In Close Partnership With You To Ensure The Suitability And Cost Effectiveness Of Our Methods.”

Each of our laboratories is staffed with highly qualified and experienced personnel and equipped with modern instrumentation to provide fast and accurate analysis of exploration and ore grade samples.

Samples can be analysed for over 60 elements including gold, PGMs and base metals by a number of techniques, including fire assay, AA, ICP-AES, ICP-MS, ISE and others.

A range of metallurgical tests can also be performed at selected laboratories.

  • Gravity Resting
  • Flotation Resting
  • Cyanidation
  • Amalgamation
  • HeapLeach
  • Bottle Roll Testing

Quality control includes the extensive use of CRMs, duplicate analysis and blanks. Random samples are repeated regularly to monitor overall quality control. We participate in the Proficiency Testing Scheme run by CCRMP, receiving top rating for all elements on all occasions. We have been awarded the Certificate of Laboratory Proficiency every year, and achieve consistently excellent results in Geostats Round Robins.

We are proactively investing in new technology to improve the quality, speed and accuracy of analysis that you need. For example, our automated, multi-pour system in the fire assay section in our laboratory in Ireland, enables 50 crucibles to be loaded at a time and simultaneously poured into moulds.
