the advantages of mining gold | our pastimes

Positive economic development is one of the primary advantages for mining gold in contemporary times. Gold mining is a sector of trade and business that governments use to improve their nation's economic systems.

Foreign Direct Investment (FDI) occurs when one country participates in another nations development. Developing countries' FDIs increase when gold mining is used to create factories and by increasing mineral exports.

The World Gold Council states that governments can tax the mining operations that produce gold. Gold mining can be advantageous for developing countries that have a limited tax base by generating extra revenue.

According to BullionVault.com, gold mining operations can be advantageous as investments because the value of the shares is related to the price of gold and gold mining stocks are valued though the lifetime of the mine.

According to the World Gold Council, developing countries accounted for 72 percent of the global output of gold. Many economically challenged nations that possess gold can use this element to improve their nation's infrastructure, employment opportunities and various sectors of society.

gold mining: competitive advantage, mine life and market potential - the hedgeless horseman

gold mining: competitive advantage, mine life and market potential - the hedgeless horseman

In the mining business a companys competitive advantage can come from things such as grade, geology and/or ease of processing. Kirkland Lakes Fosterville Mine has a very good competitive advantage due to it being one of the highest grade mines in the world. No competitor can change that fact anytime soon given that fewer and fewer high quality mines are found each year and it takes longer and longer to put mines into production. In essence, the mines competitive advantage relative to the average mine is probably more likely to expand rather than contract. There is a twist however. The twist is that this advantage will only last as long as the high grade ore lasts.

One reason why mine life is important is because it puts a cap on P/E ratios. One would not want to pay a P/E ratio of 20 if the mine life was 10 years since one would only have gotten 50% of ones investment back before the income stream comes to an end. In other words it is a value destroying proposition which I think explains why the bull market in miners that peaked 2011 led to a 80%-90% decline during the bear market, when lofty P/R ratios at high gold prices adjusted to more rational P/E ratios along a much lower gold price.

The best example of a company that could have both a long lasting competitive advantage and a long mine life is Novo Resources through the combination of extreme leverage from ore sorting technology and the scale of prospective horizons.

If the characteristics of for example Egina leads to the company being able to make use of low cost ore sorting beyond any gold miner to date then that could become a long lived competitive advantage. No other gold miner can change the characteristics of their deposits so they cant conjure up an at/near surface, loose gravel, gold deposit that shows up to 100% recoveries from ore sorting alone. No matter how much they would want it. Then add on the notion that this type of mineralization would cover hundreds to thousands of square kilometers. That could mean a mine life of decades depending on mining rate etc. Thus, whereas Fosterville might have finite zones that leads to extreme competitive advantages for a limited period of time, Egina could become a venture with both a competitive advantage in terms of costs on top of an unconventionally long mine life.

Mine life is capped by the size of the market. A gold miner can never grow more than the cumulative potential found within all its projects. If I own a gold mine and I own no more ground than what just covers said gold mine then there is no way for the company to grow bigger than that. If I own 100km2 of land and am looking for lode gold then there is potential that I will find multiple lodes of gold that are high quality enough that they could become mines sometime in the future.

What I look for in juniors is the potential to grow both resources and ultimately production. Thus, I would want to see potential for a large market. This is a big part of why I have Novo as my favorite stock since I know no other gold company with even close to the market potential I see in the slide below:

One mine is very hard to find. Finding multiple mines is something few companies or teams ever do. What I find so attractive with Pilbara is that there is seemingly gold all over the place. So finding gold isnt hard given that any and every junior that went out and tried to find gold bearing conglomerates have pretty much been successful in doing so. The all important thing however is not just finding gold but to find gold that can be economically recoverable. This is where ore sorting comes into the picture in a major way. Given the outstanding test results I see a chance for ore sorting technology to increase the odds of being able to economically recover all kinds of different conglomerates as well as the gold found in loose gravels near surface. This technology might help turn all those kilometers and square kilometers of gold bearing ground into cash flow one day.

Where most companies have trouble even finding gold in any meaningful scale, Novo already has passed that hurdle in my opinion. Thus, I am personally convinced that Novos market size potential is unparalleled and that processing techniques such as ore sorting is now the main value driver. If it can show that gold can be recovered at a profit within the Egina mining lease for example then I would expect Novo to be able to mine gold at a profit all over the 2,000-3,000km2 of prospective lag gravel areas. I think the same basically holds for any of the LATERALLY gold bearing conglomerate systems.

The lateral aspects of these systems is extremely important. A junior can own 10,000km2 of ground where they are chasing lode gold but the actual area that there is even potential for gold is a fraction of that. There might be one mine per every 100km2 in the major gold camps on average (just a guess). Compare that with owning even 1,000km2 of lateral systems like in the Witwatersrand. 1,000km2 of laterally extensive gold bearing conglomerates in the Witwatersrand might host hundreds of millions of ounces. At its peak, the Witwatersrand market was large enough to sustain thousands of companies. Thus, there is a very large difference between owning 1,000km2 of ground prospective for the rare lode gold deposit or two compared to ground where the targeted deposits extend laterally and Novo controls around 12,000km2 of land in Pilbara. This is beyond what any single mining company controlled in the Witwatersrand.

If ore sorters help show proof of concept in any system then any km2 where that system is proven to be gold bearing will jump in value. This is the reason why Novo has been forced to stake all the prospective ground first and show proof of concept later. We have all seen when an area becomes hot. All of a sudden there is a rush of juniors trying to stake every claim in sight. This of course means that the demand for ground in a hot camp goes up significantly. Just think about the revaluation of all the land in the US that covers the shale oil basins. There were a lot of people that suddenly got rich from just owning something that unexpectantly shot up in value because it might have precious oil at depth. Oil that until then could not be recovered and thus used to be valued at zero. When something that is laterally extensive goes from zero value to at least some value, then the real estate in that area goes up a lot. You can read about the skyrocketing price of land due to the shale boom here.

What the odds are that Egina will be economic to mine is something I do not know. All I know is that if proves to be economic to mine then I would argue that said mine could stretch over hundreds or thousands of square kilometers and be prove to be worth billions at the end of the day. Why? Because if the swales average 1g/m3, are 1m thick in average, covers say even 100km2, then that is around 4.8 Moz (per 100km2). Given that the first Egina swale averaged 1.7 g/m3, and it is expected to get better further north, I would not be surprised if 1g/m3 proves to be conservative. Furthermore, it seems that the current thesis is that it is far larger than 100km2. At least when it comes to total area that might be mineralized to some degree across the greater terrace (which is much much larger).

When it comes to the Mt Roe conglomerates we have heard guesstimates of either 375,000-750,000 ounces per km2. IF that proves to be true and at least some areas are economic to mine then that is basically a decent sized mine per every 2 km2. Is it any wonder why Novo has kept all the land near the outcropping areas and have even staked more land just a few weeks ago that covers outcrops of both Mt Roe and Hardey Formation? Is it any wonder why Novo who does not yet have any cash flow has been prepared to burn around $10M per year just to keep the ground (even though it will take years and years to explore)? Think about it.

We also have the Hardey Formation conglomerates such as what is found at Beatons Creek. The naysayers have said it will never be a mine. That its too complicated, patchy and too low grade. Well, Sumitomo who has been insiders for around two years certainly doesnt think so and neither does Novo. When I visited Novo last year one of the biggest take aways was how confident Novo seems to be when it comes to nuggety gold today. There was a Dutch born Novo geo who explained in great detail how their understanding of the Beatons Creek geology and nuggety nature has evolved. Even though I couldnt possibly grasp everything he said I think the proof is in the pudding. Novo has an iron clad resource today, and again, Sumitomo has given thumbs up on BC. If its good enough for a $40 B entity then it is good enough for me.

The ore sorting trials so far is telling us that these state of the art ore sorters might help unlock any and all nuggety prospects across those thousands of square kilometers. Interestingly enough it was advancements in processing techniques for gold that actually revived and then made Witwatersrand flourish into becoming the most legendary gold field in history. In other words a brand new processing technique unlocked not just one mine but the whole gold field(!). Just like new technology unlocked entire shale oil basins in the US. I think that is something to consider when it comes to ore sorters and Pilbara.

My third favorite stock is Lion One Metals primarily because the company already has a permitted project and the companys market potential is on par with Irving Resources. When it comes to competitive advantage I am not as certain but the grades are very high and if they find a feeder it might get even better.

Note: I own shares in all companies mentioned which I have bought in the open market. Novo, Lion One, TriStar and Prime Mining are banner sponsors of this site. Always do your own due diligence and draw your own conclusion!

You are very welcome! Yes, we are in uncharted waters. My core are made up of miners in the better jurisdictions. Novo at the #1 spot with operations in the #1 jurisdiction is an example. However, I do think there are some juniors located in lower tier jurisdicitons that are priced low enough to warrant speculation. If nothing bad happens they should outperform the juniors with tier 1 premiums etc. Still I wouldnt want to have a core built on the more speculative juniors. ALl the best

environmental impacts of gold mining | brilliant earth

environmental impacts of gold mining | brilliant earth

Dirty gold mining has ravaged landscapes, contaminated water supplies, and contributed to the destruction of vital ecosystems. Cyanide, mercury, and other toxic substances are regularly released into the environment due to dirty gold mining.

Modern industrial gold mining destroys landscapes and creates huge amountsof toxic waste. Due to the use of dirty practices such as open pit mining and cyanide heap leaching, mining companies generate about 20 tons of toxic waste for every 0.333-ounce gold ring. The waste, usually a gray liquid sludge, is laden with deadly cyanide and toxic heavy metals.

Many gold mines dump their toxic waste directly into natural water bodies. The Lihir gold mine in Papua New Guinea dumps over 5 million tons of toxic waste into the Pacific Ocean each year, destroying corals and other ocean life. Companies mining for gold and other metals in total dump at least 180 million tons of toxic waste into rivers, lakes, and oceans each yearmore than 1.5 times the waste that U.S. cities send to landfills on a yearly basis.

To limit the environmental damage, mines often construct dams and place the toxic waste inside. But these dams do not necessarily prevent contamination of the surrounding environment. Toxic waste can easily seep into soil and groundwater, or be released in catastrophic spills. At the worlds estimated 3,500 dams built to hold mine waste, one or two major spills occur every year.

Toxic waste spills have had devastating consequences in Romania, China, Ghana, Russia, Peru, South Africa, and other countries. In 2014, a dam collapsed at the Mount Polley gold and copper mine in British Columbia, sending about 25 million cubic meters of cyanide-laden waste into nearby rivers and lakesenough to fill about 9,800 Olympic-sized swimming pools. The spill poisoned water supplies, killed fish, and harmed local tourism.

Dirty gold mining often leads to a persistent problem known as acid mine drainage. The problem results when underground rock disturbed by mining is newly exposed to air and water. Iron sulfides (often called fools gold) in the rock can react with oxygen to form sulfuric acid. Acidic water draining from mine sites can be 20 to 300 times more concentrated than acid rain, and it is toxic to living organisms.

The dangers increase when this acidic water runs over rocks and strips out other embedded heavy metals. Rivers and streams can become contaminated with metals such as cadmium, arsenic, lead, and iron. Cadmium has been linked to liver disease, while arsenic can cause skin cancer and tumors. Lead poisoning can cause learning disabilities and impaired development in children. Iron is less dangerous, although it gives rivers and streams a slimy orange coating and the smell of rotten eggs.

Once acid mine drainage starts, it is difficult to stop. Acidic waters flowing from abandoned mines can raise acidity levels and destroy aquatic life for generations. Roman mining sites in England are still causing acid mine drainage more than 2000 years later.

The use of mercury in gold mining is causing a global health and environmental crisis. Mercury, a liquid metal, is used in artisanal and small-scale gold mining to extract gold from rock and sediment. Unfortunately, mercury is a toxic substance that wreaks havoc on miners health, not to mention the health of the planet.

For every gram of gold produced, artisanal gold miners release about two grams of mercury into the environment. Together, the worlds 10 to 15 million artisanal gold miners release about 1000 tons of mercury into the environment each year, or 35 percent of man-made mercury pollution. Artisanal gold mining is actually among the leading causes of global mercury pollution, ahead of coal-fired power plants.

When mercury enters the atmosphere or reaches rivers, lakes, and oceans, it can travel across great distances. About 70 percent of the mercury deposited in the United States is from international sources. Still more mercury reaches the United States through imported fish. Once it reaches a resting place, mercury is not easily removed. Sediments on the floor of San Francisco Bay remain contaminatedwith mercury left by the California gold rush of the 19th century.

Mercury is extremely harmful to human health. The amount of vapor released by mining activities has been proven to damage the kidneys, liver, brain, heart, lungs, colon, and immune system. Chronic exposure to mercury may result in fatigue, weight loss, tremors, and shifts in behavior. In children and developing fetuses, mercury can impair neurological development.

A gold mining boom is accelerating the destruction of the Amazon rainforest, a biologically diverse ecosystem that acts as a check on global warming. Artisanal, or small-scale, gold miners are tearing down the forest to access the rich gold deposits beneath. One study found that deforestation rates in the Madre de Dios region of the Peruvian Amazon have increased six-fold due to gold mining.

Gold mining is also responsible for releasing large amounts of mercury into the Amazons air and water. The mercury is poisoning plants, animals, fish, and people. In one city in the Peruvian Amazon, unsafe mercury levels were recorded in 80 percent of local residents. The gold mining boom does not bode well for the Amazon or the people, both locally and globally, who depend on it.

gold centrifugal concentrator - mineral processing

gold centrifugal concentrator - mineral processing

The centrifugal concentrator rotates at a high speed, generating a high G force, which can separate small gravity recovery gold (less than 50 microns), which was of previously unrecoverable with traditional mineral jigs, spiral separator, and gravity tables.In recent years, the application of centrifugal force has proved to be an effective technology for recovering fine and heavy minerals. The centrifugal force acting on the mineral particles can reach 50 times its own gravity, thus significantly increasing the sedimentation speed of the particles. As the intensity of the centrifugal force increases, the size of the particles that can be captured becomes finer.

The centrifugal concentrator can be used to recover the tailings of chromite, gold, scheelite and other heavy minerals, so as to make better use of mineral concentrates. Their operating and equipment costs are relatively low. Thanks to its less environmental impact and good recovery of fine-grained minerals, the application of centrifugal concentration has become increasingly important worldwide.

The gold centrifugal concentrator is a gravity-enhancing device. The feed slurry is introduced into a rotating drum, and the impeller rotates to form a high-gradient centrifugal field. The ore particles flow on the inner wall of the rotor and are continuously layered and deposited on the smooth inside the centrifuge wall.The lighter particles outside the bed are removed from the rotor assembly due to their lower specific gravity or smaller size. Heavy particles remain in the concentration zone, where the concentrate is cleaned with fluidized water.A rotor spins the bowl, which throws the feed coming into the center against the walls of the bowl. Light and fine particles are carried out of the bowl with the tailings while heavy and coarse particles are collected and removed from the bowl. Industrially they can operate as batch or continuous units, with pores opening intermittently to collect concentrate.
