Case Study
We were successful in obtaining a contract with a gold exploration company following a brief, initial engagement. The initial engagement was carried out to obtain data for a larger program, and to ensure that the sampling methods and practices delivered accurate and consistent results.
The Problem
The project to be drilled was a large tonne, low grade ore body.
Any sampling deficiencies and inconsistencies would have a profound affect on the assay results and ultimately the success of any drill program, collected ore body knowledge and planning.
Our customer wanted sampling equipment and techniques that would deliver accurate and consistent results.
The Solution
A review of equipment and techniques were carried out based on the requirements for the project. Of major importance were the consistency of sampling systems across multiple drill rigs, the understanding of sampling principles and practices by our supervisory and drill crews, and accurate repeatable results.
The sampling equipment on each rig was removed and checked for suitability and their similarity to the other systems allocated for the project. Crews gathered for a workshop to implement correct techniques and required outcomes.
Processes were reviewed to ensure that documented quality checks were built into all processes throughout the project.
The Outcome
The initial 10,000 metre program was executed with consistent and accurate sampling results. Sample weights were consistent and ‘split’ weights were consistently under the variance requested by the customer.
This focus on quality and approach awarded the extension program of 60,000 metres, utilising three RC drill rigs.
The customer regularly reviewed the sample data and were satisfied that they were obtaining the required outcomes to further their ore body knowledge and allow accurate planning of potential future open cut pits.
With our dedication to quality outcomes for our partner, the program delivered accurate sampling over the course of the program and was deemed a success.
