exploration methods at a heavy mineral sands deposit. The level of confidence and the risk associated with the resource calculations will be established based on the sample methodology. Two drilling methods used at Hillendale are compared statistically and visually. It is clear from the comparison that the Wallis Aircore (WAC) method is significantly better than the Reverse Circulation (RCN ...

Surface and Subsurface Methods of Mineral Exploration

Mud-rotary drilling: this method is used for drilling through soft rocks, sand and clay layers especially in the search for coal, oil or gas. A special mix of clay and water is forced down the drill hole turning a rotary bit, with rock chips returning in the "mud" slurry. This method is used for holes up to 3km deep and can be done from ships or

MINERAL SANDS - Earth Sci

Mineral sands are mined by surface mining methods including open cut mining, suction dredging and hydraulic mining. The first stage of the mining process is to remove all timber and topsoil from the mine site. The topsoil is stockpiled for later rehabilitation of the site after mining has been completed.

02/10/2011  Mineral exploration is the second stage of the key exploration activities to locate surface mineralization and any old workings in a smaller area of identified geological, geochemical, and geophysical anomalies. It is therefore the follow-up of geological, geochemical, and geophysical anomalies from a reconnaissance survey. Again in this stage geological, geochemical, and geophysical methods

Prospectivity analysis is a GIS–based predictive spatial analysis technique used to integrate multiple exploration datasets in the framework of a mineral deposit model. The output of the process is a map displaying favourability for the occurrence of a particular mineral deposit type. This powerful tool for the identification and ranking of exploration targets has been applied to studies of prospectivity for

Heavy mineral sands deposits occur in the Murray and Gippsland Basins in northwest and southeast Victoria. The Murray Basin extends from Victoria into South Australia and New South Wales where mineral sands deposits have also been identified. Two types of mineral sands deposits are recognised in the Murray Basin. These deposits are characterised as either strandline deposits or Wimmera-style

The mineral exploration industry requires new methods and tools to address the challenges of declining mineral reserves and increasing discovery costs. Laser-induced breakdown spectroscopy (LIBS) represents an emerging geochemical tool for mineral exploration that can provide rapid, in situ, compositional analysis and high-resolution imaging in both laboratory and field and settings. We

Various methods which include magnetic, gravity and electrostatic separation as well as chemical processes, are then used to separate the sands into individual mineral species. The ore is put through a screening plant which breaks it down into individual grains. The heavy mineral grains are 0.05 to 0.3mm in size, material greater than 2mm is dumped back in the mining area.

Chapter 5 Mineral Exploration

5.8 Shallow boreholes and trial pits are methods of surface mineral exploration which obtain data on the depth, extent and quality of the mineral, the make up of overburden, and hydrological data. Shallow boreholes use small rigs that are capable of sinking a number of boreholes in a day. Trial pits are mostly used in assessing shallow deposits, in particular sand and gravel. After the ...

When a favourable deposit has been identified, the main exploration method is drilling. Usually small, four wheel drive mounted reverse circulation (RC) drilling rigs are used. The RC drilling method – where air or water is forced down an annular tube and cuttings are returned up the central tube – produces a clean uncontaminated sample at the surface. These are bagged at 1 or 1.5 metre intervals and, if heavy

targets associated with exploration for heavy-mineral sands, the following aspects are important: • The narrow across-strike width of the targets requires rapid sampling magnetometers (0.1 s) to provide an along-line sample spacing of approximately 5 m. • The narrow strandline-associated anomalies attenuate very rapidly with height, so the lowest-possible flight height is required, 20 m ...

The electromagnetic (EM) method is commonly used in mineral exploration due to the method’s sensitivity to conductive targets. Controlled source audio-frequency magnetotellurics (CSAMT) is developed from magnetotelluric (MT) method with an artificial EM source to improve the signal amplitude. It has been used for mineral exploration for many years. In this study, we performed a case study of

The Appraised Value Method is based on the premise that the real value of an Exploration asset lies in its potential for the existence and discovery of an economic mineral deposit. The Appraised Value Method assumes that the amount of exploration expenditure is related to its value. Therefore, it is important to understand the definition of capital expenditure in mining industry (see Figure 3).
