Models and Exploration Methods for Major Gold Deposit Types
Selection of the appropriate exploration methods must be dictated by the characteristics of the targeted model, its geologic setting, and the surficial environment Both greenfield and brownfield exploration contributed to the discovery of major gold deposits (>25 moz Au) in the last decade but the discovery rates have declined significantlyGold mine exploration is challenging and complex It requires significant time, financial resources and expertise in many disciplines – eg geography, geology, chemistry and engineering The likelihood of a discovery leading to a mine being developed is very low less Gold Mining: Gold Exploration World Gold Councilremains very important to gold exploration, while promising new techniques are being tested Selection of the appropriate exploration methods must be dictated by the characteristics of the targeted model, its geologic setting, and the surficial environment The application of exploration technology is an important aspect of any exploration programMajor Gold Deposit Types and Exploration processApr 08, 2013 The main methods to consider are (1) existing exposures, (2) handdug holes, (3) open pits backhoe, (4) open pits excavator, (5) other machinedug holes, (6) churn drill holes, (7) other drilling methods, or (8) volume samples The special problems associated with placer evaluation:Exploration and Evaluation Methods to find gold in remains very important to gold exploration, while promising new techniques are being tested Selection of the appropriate exploration methods must be dictated by the characteristics of the targeted model, its geologic setting, and the surficial environment The application of exploration technology is an important aspect of any exploration programMajor Gold Deposit Types and Exploration process

Gold mine exploration is challenging and complex It requires significant time, financial resources and expertise in many disciplines – eg geography, geology, chemistry and engineering The likelihood of a discovery leading to a mine being developed is very low less Selection of the appropriate exploration methods must be dictated by the characteristics of the targeted model, its geologic setting, and the surficial environment Both greenfield and brownfield exploration contributed to the discovery of major gold deposits (>25 moz Au) in the last decade but the discovery rates have declined significantly[PDF] Models and Exploration Methods for Major Gold May 01, 2013 Here are some methods of exploration of alluvial gold that can be used EVALUATION OF ALUVIAL DEPOSITS One of the most difficult task associated with placer mining is the evaluation of the deposit More placer projects have failed due to inaccurate assessment of reserves than any other reason Within the realm of alluvial deposits, those Exploration and Evaluation Methods to find gold in It is widely known that portable XRF analysers are rarely used to analyse gold directly during exploration because the analysis area is large (up to 5 mm) and the limit of detection is too high The established exploration method for Au mineralisation is to use a portable XRF instrument to identify pathfinder elements that can be used as Exploration for Gold: The Reverse ApproachSometimes openpit mining is used, such as at the Fort Knox Mine in central Alaska Barrick Gold Corporation has one of the largest openpit gold mines in North America located on its Goldstrike mine property in northeastern Nevada Other gold mines use underground mining, where the ore is extracted through tunnels or shaftsMethods of Gold Mining Geology In
