REAL TIME Drillhole Assay System

A reliable alternative to coring and assaying which is cheaper, faster, more regularly sampled and more compatible for direct use in resource modelling software. Ore-Spec uses pulsed neutron technology to deliver elemental analysis directly from the drillhole. The tool consists of a neutron generator and a series of neutron and spectral gamma detectors.

The system delivers real time elemental analysis allowing our clients to optimise, reduce or replace conventional assaying services.

Pulsed Fast Thermal Neutron Activation

Features

• Ability to quantify the abundance of main elements and minerals in the formation using a high performance gamma spectroscopy.
• Continuous and depth indexed multi-parameter measurements. Greater rock volume sampling with high precision and regularity for better resource estimation.
• A reliable alternative to coring and assaying which is cheaper, faster, more regularly sampled and more compatible for direct use in resource modelling software.
• Raw data that can be readily backed up for reprocessing and re-evaluation at any time (as opposed to core).

Applications

• Quick and detailed rock elemental analysis
• In-situ quantitative and qualitative grade control
• Gamma spectrometry (Th, U and K)
• Total porosity and permeability
• Bulk density and dry bulk density estimations
• Effective ore grade screening in blast holes
