and concentration of diamond in river sediments are obviously of direct importance in the formation of economic alluvial diamond deposits (or diamond placers). They also carry a secondary significance in concentrating associated indicator minerals such as garnet, ilmenite, spinel and chrome-diopside that guide prospectors to the primary sources.

EVALUATION OF ALLUVIAL DIAMOND DEPOSITS

On alluvial diamond deposits, such studies will overcapitalise the project. Far more realistic for alluvial diamond deposits of all types are inferred and indicated resources, even a probable reserve, if absolutely required. 1. INTRODUCTION Evaluation of alluvial diamond deposits is

PLACER DEPOSITS Sub-committee Members - CIMTo identify sites appropriate for bulk sampling/trial mining sites; and, To further delineate as required the different gravel types. The following exploration sampling techniques for alluvial diamond deposits are generally carried out prior to advancing to a bulk sampling/trial mining phase. They are:Placer deposit - WikipediaIn geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. The name is from the Spanish word placer, meaning "alluvial sand". Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush.

Aug 05, 2013· Historic mining in England in the counties of Devon and Cornwall started with alluvial tin deposits, which was later followed by underground mining. In Asia, tin placers were originally mined in Malaysia, Thailand and Indonesia from as early as 3000BC. Tin mining is vital to the region's economy to this day. UraniumInvestigating the origin of alluvial diamonds in the North Alluvial mining in the area started in the early 19 th century. Renewed interest in the mining of alluvial diamonds was generated by the El Niño related drought of 1974 when many farmers turned to diamond mining. Much larger volumes of gravel could be moved and greater depths of gravel were reached owing to modern earth moving and sorting alluvial gold mining techniquesalluvial gold mining techniques. As it is my opinion that deep alluvial mining methods in Victoria and in the Murray Flats in New South Wales are practically in their infancy and considering that we the old school of alluvial miners who have thirty or forty years' experience to guide us must in the natural order of things hand over the management of our mines to the younger and less Krone - Endora at Venetia | Diamcor Mining Inc.After reviewing all elements of the past exploration, the subsequent NI43-101 report noted it was apparent the Krone-Endora at Venetia project could develop into a medium-sized diamond producer. In addition to this, it was also noted that the deposit was not only an "alluvial" deposit, but also a rare "eluvial" type of deposit indicating a
