Exploration here is the work of finding and defining a deposit — sampling, drilling, assaying, and the reporting standards that govern what an explorer may claim. (For the technologies that make that work possible, see Exploration Technology under Innovation & Technology.)

Defining a mineral-sands deposit asks a question that most exploration does not. It is not enough to establish how much heavy mineral is present; what matters commercially is which minerals make up that fraction, in what proportions, and whether the valuable ones can be separated from the rest. A sand containing a given quantity of heavy mineral may be an ore or may be nothing at all depending on how much of it is rutile, ilmenite and zircon rather than iron oxides and altered material with no market. Sampling and laboratory work therefore run in parallel: a heavy-mineral determination on one hand, an assemblage determination on the other, with grain size, slimes content and oversize all recorded because each will later decide what a plant can do.

The sequence is a discipline in its own right: sample collection and the drilling styles suited to unconsolidated and cemented ground, quality control and the duplicate and standard sampling that makes a result defensible, and the reporting codes themselves — how an Exploration Result differs from a Mineral Resource, who signs for it, and why a competent person's judgement is the pivot on which any disclosure turns. The vocabulary of announcements is precise rather than decorative, and an announcement read against it says exactly what it does and does not establish.

The instruments themselves belong to Exploration Technology, which this page is written against. Metallurgy takes up the testwork that follows sampling, Mining Methods what a defined deposit could support, Exploration Companies the firms doing this work, and Zirconium/Zircon one of the minerals whose proportion in the assemblage decides so much.
