Representative samples are obtained from at least five locations in the pile during miniature stockpile reduction method.

• A. True
• B. False
• C. Not specified
• D. Only from the top surface

Answer: (A)

Representative sampling from a stockpile requires collecting material from multiple spots to capture the pile’s variability. In the miniature stockpile reduction method, taking samples from at least five locations ensures the composite reflects differences that can occur across the pile—such as variations in particle size, moisture, and any segregation that happens during storage. Relying on material from only the top surface or from a single area would bias the results and give an inaccurate picture of the overall quality. Therefore, this practice is true because it uses multiple sampling points to produce a representative sample of the entire pile.
