Stockpile Inventory Audit in the Metal Industry

Client  Overview:

A leading company in the metals industry, which maintains stockpiles of ores, metals, and other related commodities, required an accurate stockpile inventory audit to ensure precise financial reporting, regulatory compliance, and informed purchasing decisions.

Project Scope:

Conti Testing was engaged to conduct a comprehensive inventory audit of the client’s stockpiles. The audit covered more than 30 piles, representing 100,000’s of tons of material. To achieve the highest accuracy, the project required precise sampling, laboratory analysis, and density calculations.

Our Approach:

1. Representative Sampling
   • Our team strategically collected representative samples from all stockpiles to ensure comprehensive coverage and compliance with recognized industry methods.
2. Laboratory Analysis
   • The collected samples, representing approximately five tons of material, were transported to our laboratory, where they were dried using industrial ovens to remove moisture and prepare them for further testing.
   • Precise bulk density measurements were conducted on the dried samples in accordance with ASTM methodologies, ensuring accurate inventory calculations.
3. Volume Overlay & Inventory Determination
   • The measured bulk densities were overlaid with volume data obtained through pile flyover analysis. This approach enabled the precise determination of inventory levels for each commodity.

Results & Impact:

• Delivered accurate and reliable stockpile inventory data, essential for financial reporting.
• Ensured regulatory compliance through precise material accounting.
• Enabled strategic purchasing decisions by providing a clear understanding of available inventory.
• Improved operational efficiency by identifying discrepancies and optimizing inventory management practices.

Conclusion:

By leveraging our expertise in sampling, laboratory testing, and precise density calculations, Conti Testing’s stockpile inventory auditing approach provided the client with actionable insights, ensuring compliance, accurate reporting, and improved decision-making.
