ISO surveillance audit finds no gaps nor corrective actions needed for TVIRD projects

In this year’s external ISO surveillance audits, the group of mining companies under TVI Resource Development Philippines Inc. (TVIRD) recorded an outcome that runs against the usual expectation of standard assessment. Across all its project sites, auditors did not identify nonconformities, procedural gaps nor corrective actions required at the end of the inspection. An exercise meant to test whether systems hold under scrutiny instead recorded no findings that warranted correction.
External ISO surveillance audits are structured to probe operational systems against international standards, assessing whether documented procedures are reflected in actual practice and controls remain effective under sustained review. In most settings, these audits surface at least minor deviations requiring attention. In this case, none were reported.
Retained certifications
Across its operations, TVIRD’s Greenstone Resources Corporation in Surigao del Norte maintained its Integrated Management System (IMS) certifications under ISO 9001:2015 for Quality Management, ISO 14001:2015 for Environmental Management, and ISO 45001:2018 for Occupational Health and Safety for its operations at the Siana Gold Project.
The company’s Agata Nickel Laterite Project in Agusan del Norte – which is now on its final rehabilitation stage – and the Balabag Gold Project in Zamboanga del Sur likewise sustained their respective compliance certificates under ISO 14001:2015 Environmental Management.
The results effectively reflect full retention of certifications across multiple management systems during external surveillance audits, alongside a clean evaluation record for the period under review.
Strength and discipline
ISO Officer Arbette Dayandayan described the outcome as a reflection of system strength and consistency in execution.
“Achieving zero non-conformities in this year’s external audit is a clear validation of Greenstone’s IMS and operational discipline. It signifies that all processes are fully aligned with ISO requirements, implementation is effective, and systems are mature, proactive, and continuously improved,” she said.
She added that the company regards compliance as a condition embedded in its daily operations rather than a periodic requirement.
Corporate dress rehearsals
Ahead of the audit, Greenstone implemented a risk-based preparation framework covering leadership engagement, hazard identification, legal compliance tracking, operational controls, workforce competence, and emergency preparedness. Internal audits and gap assessments were conducted across all operational units, while mock audits were also carried out to simulate external review conditions.
Workforce preparation included awareness sessions, drills, and ISO briefings. Meantime, management reviews and corrective action tracking addressed identified risks prior to external evaluation.
Unified systems
Within the IMS, compliance is maintained through standardized operating procedures, structured risk assessments, document control mechanisms, inspections, and performance monitoring tools. These are reinforced by leadership oversight and coordination across departments.
Document Controller Alexa Mae Tiape emphasized that proper documentation is the central pillar of system integrity. “Documentation is the bedrock of any successful management system, and we act as custodians of compliance. We safeguard operational integrity,” Tiape stated.
She likewise explained that documented information is managed through a controlled lifecycle: from creation, review and approval to storage and disposition – all the while ensuring traceability and alignment with ISO requirements.
A clean audit outcome
The recent audit result establishes the critical context for evaluating both quality and compliance frameworks. When structured evaluations consistently return no findings, it reflects stability in execution. Moreover, it also underscores how closely systems operate within defined parameters.
For the TVIRD Mining Group, the result points to a system that operates within set parameters. It likewise reflects consistency in implementation across operational levels.
In an evaluation designed to surface gaps, the most defining result for the organization was not the need for correction – but rather, that it is not necessary at this time.
