Mining Exploration Process How Explorers develop an exploration strategy, how they develop an exploration model and design an exploration program and select the optimal exploration tools to carry out that program. As usual of the talk will end with a series of learning points from this talk.
The expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations; however, the value of gold has led to millions of small, artisanal miners in many parts of the Global South .

Newmont Gold Company later became the company's only major asset while the acquisition of Santa Fe Pacific Gold in 1997 increased Newmont's options for optimising mining and processing. In early 2001, Newmont acquired Battle Mountain Gold Co. and in 2002 Normandy Mining, so further extending its gold mining and exploration base in Nevada.
This process involves a detailed exploration of the area to determine the viability of a gold mining location. Factors such as the presence of gold deposits, the accessibility of the site, and environmental considerations must be taken into account.
At current gold prices this is worth about US600. Both smelter treatment charges and oxidation or bioleach costs are at least 200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around Clearly this is a function of gold price, but in the current gold price and cost ...
The methods employed for gold exploration are very similar to exploration for other metallic and nonmetallic mineral resources. Typically, exploration efforts for new mineable prospects are extensions of currently operating mines or nearby regions with similar geologic conditions. ...

"Anatomy of a Mine" was first prepared in looseleaf form to aid Forest Service land managers and other administrators with mineral area responsibilities. The material summarized legislation affecting mining, defined mining terms, and discussed basics of mineral exploration, development, and operation in the West. The goal then as
Mineral exploration of gold, silver and PGM metal ores becomes more challenging every year. Mines increasingly facing lower ore grades and complex mineralogy, forcing mills and concentrators to process more material. Mine planning, separation and concentration are directly related to mineralogy, metallurgy and variability of the ore body.
Processing gold involves transforming rock and ore into a metallic alloy of substantial purity known as doré typically containing between 6090% gold. During its life, a number of factors such as the price of gold or input costs will affect which areas of an ore body are deemed profitable (economic) to mine.
The 5 Lifecycle Stages of Mining. 1. Exploration Prospecting Stage. This is the first and most essential step of the mining process: in order to open a mine, companies must first find an economically sufficient amount of the deposit (an amount of ore or mineral that makes exploitation worthwhile.)
SteepSlope Mining. At the end of 1999, only openpit mining was employed in the Zijinshan gold mine after several technical modifications. Through theoretical exploration and engineering practice, steepslope (α = 75°, β = 31°38°) mining was adopted (as shown in Fig. 2a).In addition, the number of bench groups and width of the working platforms were 46 and 3560 m, respectively.
Exploration occurs at all stages of the active mining cycle and extends or returns to recognized resources. Continuing to develop and derisk potential resources aids in the extension of the life of an operational mine. Gold Mining and Extraction OpenPit Mining

The most widely used exploration technique is the drilling of probe holes. In this practice a drill with a diamondtipped bit cuts a narrow kerf of rock, extracting intact a cylindrical core of rock in the centre ( see core sampling ).
The exploration drilling at the Masbate gold project began in April 2010 and was carried out until April 2011. It included 55,000m of drilling and 15,000m trenching. On 12 April a new exploration license was granted to the project. The new permit extends ² and is contiguous to the tenements currently mined.
