With the Cortex MDP system already being operational on other sites, the particular aim of this project was to extract specific data sets from the high-resolution log files that were available and use post-processing machine learning to generate quantifiable results.

The values produced were being confirmed by both the wire-line surveys and the physical geological results. Whilst this process is still being developed, the automation of the file analysis means that, as soon as the high-resolution hole log-files are available to Cortex on our servers, it is immediately and automatically processed into the new ‘lightweight’ format (.LAS) ready for delivery to the client (also automated).

As such Cortex has processed over 2500 holes (200,000m) worth of data for Rio Tinto from their new exploratory site.

Cortex’s rapid data analysis tools have meant the usual turnaround of a hole being logged manually has been reduced from weeks/months, to automatically in less than 10 seconds, with the data ready for review from anywhere in the world.

The analysis platform in the NURV system is capable of processing hundreds of holes worth of data per second, and mapping entire drill patterns and mine sites/regions, both in location and in a 3D rendered subsurface plot.
