Nevada, by the way, is the top gold producing state in the U.S., responsible for nearly three quarters of annual output. If it were its own country, Nevada would be the fourth largest gold producer in the world, thanks to its prolific Carlin Trend deposits. Nevada is considered the mining State and new mineral deposits are placed up for permitting each year. Due to Nevada's mining laws it is still one of the best states to open a new mine.
Prospectors & Developers Association of Canada (PDAC) conference in Toronto is one of the largest mining conferences in the world. More than 25,000 people turned out this year, many of them selling equipment services, exhibiting securities and investments, making presentations and much more.
One of the dominant thoughts on everyone’s minds was Barrick Gold’s $17.8 billion hostile takeover of its longtime rival Newmont Mining.
After both parties spoke with top shareholders, the bid fell through. But rather than continuing to duke it out in the capital markets, the two mining giants will instead be entering into a joint venture (JV) in Nevada, USA. The JV will combine significant deposits and mines, processing facilities and infrastructure to unlock significant synergies.
As a standalone company, the Nevada complex will be the world’s single-largest gold producing operations, according to equity research firm GMP Securities.
I see these deals as a sign that miners anticipate a bull run in gold prices. Better to invest the money now when valuations are attractive rather than later when companies could be much more expensive. During the last bull market in gold prices, many mining executives ended up losing their jobs because they entered deals when valuations were overextended.

After mining finishes, the mine area may undergo land rehabilitation. Waste dumps are contoured to flatten them out, to further stabilize them. If the ore contains sulfides it is usually covered with a layer of clay to prevent access of rain and oxygen from the air, which can oxidize the sulfides to produce sulfuric acid, a phenomenon known as acid mine drainage.[18] This is then generally covered with soil, and vegetation is planted to help consolidate the material. Eventually this layer will erode, but it is generally hoped that the rate of leaching or acid will be slowed by the cover such that the environment can handle the load of acid and associated heavy metals.[19] There are no long term studies on the success of these covers due to the relatively short time in which large scale open pit mining has existed. It may take hundreds to thousands of years for some waste dumps to become "acid neutral" and stop leaching to the environment. The dumps are usually fenced off to prevent livestock denuding them of vegetation. The open pit is then surrounded with a fence, to prevent access, and it generally eventually fills up with ground water. In arid areas it may not fill due to deep groundwater levels.[20] Instead of returning the land to its former natural state, it may also be reused, converting it into recreational parks or even residential/mixed communities.[21]Copyright 2014 American Diatomite, Inc.
Open-cast mines are dug on benches, which describe vertical levels of the hole. The interval of the benches depends on the deposit being mined, the mineral being mined, and the size of the machinery that is being used. Generally, large mine benches are 12 to 15 metres thick.[5][6] In contrast, many quarries do not use benches, as they are usually shallow.[7] Mining can be conducted on more than one bench at a time, and access to different benches is done with a system of ramps. The width of each bench is determined by the size of the equipment being used, generally 20-40 metres wide.[8] Downward ramps are created to allow mining on a new level to begin. This new level will become progressively wider to form the new pit bottom.[9]
Most walls of the pit are generally mined on an angle less than vertical. Waste rock is stripped when the pit becomes deeper, therefore this angle is a safety precaution to prevent and minimize damage and danger from rock falls. However, this depends on how weathered and eroded the rocks are, and the type of rocks involved. It also depends on the amount of structural weaknesses occur within the rocks, such as a faults, shears, joints or foliations.
The walls are stepped. The inclined section of the wall is known as the batter, and the flat part of the step is known as the bench or berm. The steps in the walls help prevent rock falls continuing down the entire face of the wall. In some instances additional ground support is required and rock bolts, cable bolts and shotcrete are used. De-watering bores may be used to relieve water pressure by drilling horizontally into the wall, which is often enough to cause failures in the wall by itself.[10]
A haul road is usually situated at the side of the pit, forming a ramp up which trucks can drive, carrying ore and waste rock.[11]
Open-pit mines create a significant amount of waste. Almost one million tons of ore and waste rock can move from the largest mines per day, and a couple thousand tons moved from small mines per day.[12] There is generally four main operations in a mine that contribute to this load: drilling, blasting, loading and hauling.
Waste rock is hauled to a waste dump. Waste dumps can be piled at the surface of the active pit, or in previously mined pits.
Leftover waste from processing the ore is called tailings, and is generally in the form of a slurry. This is pumped to a tailings dam or settling pond, where the water is reused or evaporated. Tailings dams can be toxic due to the presence of unextracted sulfide minerals, some forms of toxic minerals in the gangue, and often cyanide which is used to treat gold ore via the cyanide leach process. If proper environmental protections are not in place, this toxicity can harm the surrounding environment.[13]
Open-pit mining involves the process of disrupting the ground, which leads to the creation of air pollutants. The main source of air pollutants comes from the transportation of minerals, but their are various other factors including drilling, blasting and the loading and unloading of overburden.[14] These type of pollutants cause significant damage to public health and safety in addition to damaging the air quality. The inhalation of these pollutants can cause issues to the lungs and ultimately increase mortality.[15] Furthermore, the pollutants affect flora and fauna in the areas surrounding open-pit mines.
Open-pit gold mining is one of the highest potential mining threats on the environment as it affects the air and water chemistry. The exposed dust may be toxic or radioactive, making it a health concern for the workers and the surrounding communities.[16]
A form of open-cast quarrying may be carried out as 'untopping'. This is done where a previous underground mine is becoming uneconomic or worked-out, but still leaves valuable rock in place, often as a result of pillar and stall working. Untopping removes the overburden from above this, opens up the mine from above, and then allows the previously 'trapped' minerals to be won.
Untopping was a feature of Welsh slate workings in the 1930s and 2000s, where Martyn Williams-Ellis, manager at Llechwedd found that earlier Victorian workings could be kept profitable with the newly mechanised techniques for bulk excavation to extract their pillars, and more recently across a number of worked-out mines.
