This review highlights two differing approaches to sampling, namely: * The application of the Theory of Sampling, originally proposed by Pierre Gy, to sampling of precious and base metal products * The application of ISO standards for sampling of bulk commodities, or where ISO standards are not available, procedures agreed in terms of contracts between buyers and sellers.

While bulk sampling per se is a valid method and bulk samples do, in many cases, offer the most satisfactory method of testing erratic, highvalue ground, they are at the same time open to certain criticism. For example, bulk samples must be representative of the deposit, a feat not easily achieved where they are few in number.
