Validation of 3D Drillholes in ArcGIS Pro

Esri User Conference | San Diego | 9-13 July

Session: 2351 - Modelling and Conservation 
Date: Thursday, 12 July
Time: 1pm - 2pm
Validation of mineral exploration results is crucial to provide the transparent and accurate information required by public Resource and Reserve reporting regulations.

In this presentation, Dr Mike Cunningham will showcase a new data validation extension he has developed for ArcGIS Pro that allows the creation of drill holes in 3D space with full attribution. The extension supports the validation of input data, generating 3D drill trace or desurvey points, validation of geometry and attributes and data visualisation while also integrating with mobile data collection applications.

This allows geologists to validate a borehole database ensuring no overlap or duplicate segments and fix issues by flagging values without altering the base data. Thus, users can import and validate results before passing on to the Resource geologist for Mineral Resource estimation.

A key benefit of this tool is the ability to integrate with existing GIS workflows, without the need to purchase expensive additional programs. This provides a user-friendly system that can enable users to deliver better quality data, reducing risks and potentially improve project outlooks.

Mike Cunningham
Principal Consultant, Geology

Mike has over 17 years’ experience as a geologist. He completed a PhD in post-Variscan tectonics (Ireland) and later completed two years of postdoctoral research into evaluating and modelling active oceanic slope processes. Mike has also worked in both Irish and British civil services where he was involved in shallow seabed mapping, GIS and software development. Mike’s experience with SRK includes projects in Australia and overseas, and on a variety of commodities including graphite, gold, uranium, iron and potash. He has conducted 3D modelling of vein, epithermal and banded iron formation styles of mineralisation, and Mineral Resource and exploration target estimates in accordance with JORC Code (2012) reporting guidelines. Mike has also completed numerous Independent Geologist’s Reports, due diligence, valuation studies, and is a well-accomplished project manager.
