There is significant opportunity to rapidly add value through low cost exploration activities over areas of known heavy mineral sand (HMS) mineralisation to discover large tonnage, high grade sweet spots and high unit value resources. The potential exists for a long mine life mining asset under a number of staged mining and process scenarios.

This report provides a descriptive model of heavymineral sands, which are sedimentary deposits of dense minerals that accumulate with sand, silt, and clay in coastal environments, locally forming economic concentrations of the heavy minerals. This deposit type is the main source of titanium feedstock for the titanium dioxide (TiO2) pigments industry, through recovery of the minerals ilmenite ...
Heavy minerals sometimes get naturally concentrated as a heavy mineral sand and there were, of course, no bromoform involved. It was moving water either in a stream or beach that did the job. Sometimes the sand is so concentrated in heavy minerals that it has a real economic value as an ore. Sand collectors also love these black sand deposits ...
concentrates heavy minerals in favorable settings along the coast. Accordingly, the recognition of these traps forms an important component of a heavy mineral exploration campaign. For example, heavy mineral deposits such as the Yoganup, Capel, Minninup and Eneabba in Western

Coburn HMS Project 1. General Background. Heavy minerals, such as zircon, titanium dioxide minerals, garnet, sillimanite, kyanite, and staurolite, are eroded from their parent igneous or metamorphic rocks and are transported by water and/or wind action over long periods of geological time, often ending up in the same locations as placer such deposits contain sufficient ...
Mineral sand deposits are formed from the erosion and weathering of preexisting igneous rocks such as granite, pegmatite and basalt. Over 60 to 200 million years the combinations of wind and water from ancient rivers and seas have leached the minerals from their past rocks and concentrated them into beach and dune deposits.

A common terminology of "black sand" is often used in connection with these deposits as many of the minerals in the heavy fraction are dark in color. "Ruby sand" is also used to designate those deposits having a high concentration of garnet. The term "radioactive blacks" has more recently been applied to
The aim of this thesis study is to increase the geological knowledge on the presence of Heavy Mineral Sands (HMS) in the concession areas owned by Guinea Alluvial Mining (GAM) in Guinea. In order to achieve this aim the following main research question has been formulated: Does exploration of the concession areas show sufficient Heavy Mineral Sand prospectivity for further exploration?
