Audits & Assessments

Sample Preparation and Chemical Analysis

Conducting an audit of a chemistry laboratory yields benefits that collectively enhance the laboratory’s overall performance. Such audits, often aligned with recognised standards like ISO 17025, reinforce quality assurance by verifying compliance with regulatory requirements and industry best practices. The scrutiny of analytical procedures, equipment calibration, and measurement methods during an audit not only improves the accuracy and precision of results but also validates the reliability of laboratory methods. Additionally, audits optimise operational efficiency by evaluating and refining workflows, documentation systems, and safety protocols, thereby mitigating risks associated with environmental impact and compliance. 

The process contributes to continuous improvement initiatives, identifying areas for enhancement in procedures, personnel training, and equipment maintenance. Beyond technical aspects, audits bolster client confidence, foster customer satisfaction, and ensure legal compliance. Moreover, they serve as a platform for professional development, aligning laboratory personnel with evolving industry benchmarks and best practices. Ultimately, a well-executed audit contributes to resource optimisation, data integrity, and the overall credibility of the laboratory, positioning it as a trustworthy provider of accurate and reliable analytical services. 

Throughout the audit, the auditor looks for evidence of continuous improvement initiatives, ensuring that the laboratory actively identifies areas for enhancement and implements corrective actions. The audit concludes with a comprehensive report detailing findings, including any non-conformities, observations, and recommendations. This report serves as a basis for the laboratory to address identified issues and continually improve its processes, contributing to the overall quality and reliability of the laboratory’s analytical results.

Metal Accounting

A metal accounting audit brings forth significant advantages for mining and metallurgical operations, playing a pivotal role in ensuring accuracy, transparency, and efficiency in the management of metal production data. This process provides a robust mechanism to validate the reliability of metal accounting systems, ensuring that the recorded metal quantities align with the actual production figures. By identifying and rectifying discrepancies in measurements, sampling, and reporting, a metal accounting audit enhances the precision and integrity of metallurgical data. This not only instils confidence in stakeholders and regulatory bodies but also contributes to optimised resource utilisation and cost-effectiveness in metal production processes. Additionally, the audit aids in compliance with industry standards and regulatory requirements, mitigating the risk of legal issues and potential liabilities. Furthermore, a well-executed metal accounting audit facilitates continuous improvement by pinpointing areas for refinement in data collection methodologies, process controls, and documentation practices. Ultimately, the benefits extend beyond operational accuracy, encompassing enhanced stakeholder trust, improved decision-making, and the establishment of a robust foundation for sustainable and responsible metal production practices.


Plant and Beneficiation

An audit of sampling practices of a mine process plant offers substantial benefits in ensuring the reliability and accuracy of the collected samples, a critical aspect of effective mineral processing and resource estimation. By scrutinising sampling procedures, the audit helps identify and rectify any inconsistencies, biases, or errors that may compromise the representativeness of the samples. This, in turn, ensures that the data derived from the samples truly reflects the composition of the ore or material being processed. The audit contributes to improved metallurgical accounting, aiding in precise determination of metal grades and recoveries. Moreover, it enhances the credibility of the mine’s resource estimates, providing stakeholders and investors with accurate information for decision-making. The reliability of samples is paramount for assessing the economic viability of a mine and complying with regulatory standards. Additionally, a well-executed sampling audit promotes operational efficiency by optimising sample collection methodologies and ensuring adherence to best practices. Ultimately, the benefits extend to increased confidence in the mine’s production data, facilitating better-informed decision-making, and supporting sustainable and responsible mining practices.

Exploration and Production Geology

Conducting an audit of Exploration and Production Geology processes in the mining industry yields significant advantages by ensuring the accuracy and reliability of geological data crucial for decision-making. This audit evaluates exploration methodologies, data collection techniques, and geological modelling practices, guaranteeing the precision of resource estimates. It enhances the credibility of geological interpretations, fostering investor confidence and facilitating more informed investment decisions. Additionally, the audit identifies and rectifies any discrepancies or shortcomings in the exploration and production geology workflows, contributing to improved exploration targeting and ore body delineation.

By aligning practices with industry standards and best geological practices, the audit helps mitigate risks associated with inaccurate geological models. Furthermore, the process contributes to the optimisation of resource utilisation, ensuring that exploration efforts are targeted efficiently. The benefits extend to supporting responsible mining practices, compliance with regulatory standards, and fostering a culture of continuous improvement in geological processes, ultimately enhancing the overall success and sustainability of exploration and production activities in the mining sector.

During the audit process, several key steps are taken to validate the integrity and accuracy of core-related data. The geologist is requested to extract core from a recently drilled and logged borehole, and the core recoveries are cross-checked against records in the borehole database specific to that borehole. Verification is conducted to ensure that the borehole in question was logged by a qualified geologist. The metadata of logged and sampled boreholes, along with assay information from the laboratory, is checked for its inclusion in records. The audit requests a list of such boreholes from the year preceding the audit date and randomly selects one or two for detailed verification, including drilling dates and the name of the logging geologist. Validation is sought regarding the capture and storage of core photos from the logged borehole. Additionally, the geologist is asked to extract core from a recently drilled, logged, and sampled borehole to validate the correspondence of begin and end depths of samples with the geology database, against the indications in the core box.  Core cutting is scrutinised for adherence to established protocols. The masses of primary core samples are verified against records, and confirmation is sought on whether core sample masses are accurately recorded on dispatch documentation. These meticulous steps contribute to ensuring the accuracy and reliability of core-related data within the audit scope.
