San Martín Group completed the sustainability assessment of Achilles, the international supplier prequalification network used by buyers in mining, energy and industry worldwide, and obtained a rating of 4 out of 5 stars, with a verified overall score of 74/100. The rating is valid from June 2026 to June 2027.
Achilles does not work as a self-declaration survey: the information each supplier submits is validated against documentation before a score is assigned. It is the platform where many of the large buying companies — including the operators of the main mining projects — manage supply chain risk and prequalify contractors before inviting them to bid.
Nobody required this of us. We came forward voluntarily because we want to be measured with the same yardstick used for world-class suppliers.
What the rating measures
The assessment covers four pillars: Environment, Social, Governance and Finance. In the latter, San Martín Group scored 96 out of 100: financial strength to sustain large-scale, long-term contracts. It is one of the factors that weigh most when a mining company or an EPC prequalifies contractors, because a financially fragile supplier is a direct operational risk to the project.
The overall score of 74/100 places the company in the 4-star range of Achilles' international standard, with the full assessment verified by the organisation.
The fifth star: a declared path
Our reading of the result is deliberately demanding: we do not have the fifth star yet — and that is the news. The assessment returns a precise map of what is missing, and that map is now part of the company's management plan.
Already under way:
- ISO 9001, ISO 14001 and ISO 39001 management systems under implementation, with the requirements of multinational clients as the benchmark.
- A fleet with an average age of 2.8 years and road-train (bi-tren) units that cut CO₂ emissions by around 32% per tonne transported on trunk corridors.
- Satellite monitoring of 100% of operations — the traceability backbone that management systems demand.
The next step in the plan is to deepen the environmental measurement of operations — including the carbon footprint — to close the gap in the pillar the assessment flagged with the most room for improvement. The goal is explicit: the fifth star.
What this means for our clients
- Faster prequalification: buyers registered on Achilles can verify the company's profile and documentation directly on the platform, under Achilles ID 00278019.
- Counterparty risk assessed by an independent third party, with a verified, current score.
- A supplier that measures itself and improves: the ESG requirements mining companies push down their value chain find in San Martín Group a contractor that already speaks that language.
With more than 45 years of continuous operation and an integrated mixed fleet — road trains on trunk corridors and 6×4 units for the final leg to the mine site — the company now adds an internationally verified credential to its proposition for the mining sector.
