Mining Company Warehouse Inventories and Operational Audit

Located in the state of Colima, Peña Colorada is one of the largest iron ore operations in Mexico. The project is owned in equal parts by ArcelorMittal and Ternium. Peña Colorada is a mining company that produces about 30 percent of the iron ore used in the national steel industry.


Peña Colorada has five warehouses of materials and spare parts used to maintain machinery and equipment used for the extraction of the mineral iron ore. The mining company needed a solution to complete inventories and an operational audit, so required RGIS to provide the following:

  • Identify variances to expected stock levels
  • Update stock on hand levels for all stock
  • Perform an operational audit
  • Provide accurate reports to identify any operational issues
  • Adhere to the strict health and safety measures in a mining environment


Peña Colorada partnered with RGIS to complete the warehouse inventory and operational audit project, and RGIS provided the following:

  • All auditors received safety training and security checks in accordance with accessing a mine site
  • Scheduled a team of 9-15 experienced RGIS auditors, per day over 16 days, for the warehouse counts
  • The operational audit was carried out by 1-3 experienced RGIS auditors, per day over 21 days, reviewing the labelling and variances identified
  • Reported on any variances to the customer’s system
