ELKO — Newmont Mining Corp.’s Exodus mine claimed the life of a miner from Spring Creek who died last Friday.
According to Newmont officials, Allen Campbell, 49, died in an accident. However, the Mine Safety and Health Administration has not issued any preliminary report, but listed the cause of the fatality as a slip or fall of the victim.
The MSHA classified mining accidents to include falls or slips from an elevated position or it can come be in the same level resulting from getting on or off machinery or haulage equipment that is not moving. It can also be falls and slips while operating or repairing equipment or machinery, and even stepping in a hole.
It was 2 p.m. when the accident happened at the mine located 25 miles north of Carlin. The officials from MSHA and Nevada State Mine Inspector’s Office were immediately informed of the incident. They are now working with Newmont to investigate the cause. No other information was given out.
Mary Korpi, Newmont’s Director of External Relations said that right now all information is speculative as to what happened. The news greatly affected not only his family, friends, co-workers but the whole mining industry as well.
Campbell is mourned by his wife, Julie, and two children, Levi and Jacob. According to Newmont, Campbell has been working for the company in1988. Beginning as a surface mining worker, he was later transferred to underground operations in 2001.
Tom Kerr Sr., regional vice president, North America Operations expressed sympathies from the company when he said that they are deeply saddened by the tragic loss of their friend and colleague, Allen Campbell. Their thoughts and prayers are with Allen’s family and friends, and they will continue providing support and assistance during this extremely difficult time.
This marked the first Nevada mine fatality for 2012 which is the 12th metal and non-metal mining fatality in the nation; but it excludes coal mining deaths.

The History Of Diamonds
The history of diamonds began billions of years ago when diamonds were first being formed under incredible heat and intense pressure deep below the earth’s surface. The volcanic eruptions millions of years ago forced the diamonds up to the surface where they were scattered along oceans and rivers.
The first diamonds were thought to be discovered in India around 800 B.C. No one ever discovered the volcanic eruption that it came from but the river bed deposits were plentiful enough to supply most of the word’s diamonds up till the 18th century.
The word diamond comes from the Greek word “adamas”. It means unconquerable in reference to the eternity of love. In 1477 Archduke Maximilian of Austria put the name to the test when he gave a diamond ring to Mary of Burgundy when he wanted to marry her. This started the tradition of diamond engagement rings which became all the rage at the time and hence started the popularity that diamonds experience today.
The largest amount of gem quality stones are found in South Africa but they are also discovered in Russia, South America, and the United States. The mining outside of South Africa produces industrial quality diamonds mostly. In 1866 one of the first South African diamonds was discovered by a young boy along the banks of Val River. It was a 21 carat gem that later became part of the gavel used by the Premier of South Africa.
After this discovery many diamond diggers began finding other diamonds along in the Val and Orange rivers. Below this yellow earth a layer of blue-gray rock called “blue ground” or “kimberlite” was discovered. This 60 mile coast of the Orange River divides South and South West Africa is owned by Consolidate Mines of South West Africa which is part of the DeBeers group, which have produced almost 1 million carats of diamonds a year since 1956.
The largest diamond bearing “blue ground” is in Murfreesboro, Arkansas. This is where the largest diamond was ever discovered in the United States. It was named “Uncle Sam” and was a whopping 40 carat stone. Murfreesboro Mine has become quite the tourist attraction because of this and has yielded over 60,000 diamonds since it was first discovered in 1906.
Only about one-fifth of the diamonds that are mined can be considered gem quality once they are discovered. Depending on how deep the diamond is found it make take the processing of 40 to 250 tons of gravel and sand to recover just one rough diamond from the world’s thinning diamond deposits.
It is a long process that ends with the separation of diamonds by size, shape, and quality. Only 20% to 25% are actually made into jewelry, most are used in industrial applications such as drilling, grinding, and sawing. Within 30 to 40 years experts think that all known supplies of diamonds will be completely depleted.


Bryntail Lead Mine Buildings
History, tourist information, and nearby accommodation
The Bryntail mine worked the western end of the Van Lode, a seam of barytes and galena extending from Llanidloes towards Aberystwyth. There were three shafts, named the Gundy, Western, and Murray shafts.
Of these, the best surviving is Gundy's Shaft, and most of the restored mine buildings are related to this shaft. Western Shaft lies beneath what is now Llyn Clywedog reservoir, built to control flooding on the upper Severn. Murray's Shaft was simply swallowed up by the undergrowth.
The site opened in 1708 and continued in operation until 1788. Lead ore was extracted at Bryntail and shipped into Llanidloes where it was loaded onto small boats and carried down the River Severn to the sea.
Mining stopped in 1788 but the mine workings continued to be used for almost a century after ore was discovered at nearby Y Fan. The discovery led to a boom in mining activity, and for the decade between 1870 and 1880, the Llanidloes area produced more lead ore than the rest of the world put together.
The boom did not last, and by 1884 Bryntail closed down. The mine buildings quickly fell into decay.
There are crushing houses, ore bins, water tanks, roasting ovens, and a barytes mill on the site, as well as administrative buildings such as the mine manager's office, storage buildings, and a smithy.
Bryntail is in the care of Cadw, and the site is currently open to visitors at any reasonable hour. The mine stands very close to the Glyndwr Way long distance footpath.
The site is signposted off the B4518 west of Llanidloes and is very easy to find. A footbridge leads across a rushing stream to the mine site. What is really amazing about Bryntail is just how close the mine is to the reservoir dam, which seems to loom over the site.
You can wander amid the ruined mine buildings and there are good information plaques to help you figure out what each part of the site was used for.
I quite enjoyed exploring Bryntail; the location below the dam is unforgettable, and it was rather poignant to explore a deserted site that was once the hub of the busiest lead ore mining area in the world.

Gold mining is the process of extracting gold from the ground. Gold has been mined for centuries and has been a valuable commodity for many cultures. The modern day gold miner uses a variety of techniques to extract gold from the ground.
The most common method is placer mining, which uses water to wash the gold from sediment deposits in rivers and streams. Other methods include panning, dredging, and hard rock mining.
Gold mining is the process of extracting gold from the ground. Gold has been mined since ancient times and was one of the first metals used by humans. Gold is often found in association with other metals such as copper and lead.
Gold is a very rare metal and its high value has made it a target for thieves throughout history.
How Gold Mining Works
Gold mining is the process of extracting gold from the ground. Gold is a valuable commodity and has been used for trade and currency for centuries. The process of gold mining is relatively simple and has changed very little over the years.
Gold deposits are found in a variety of geological settings all around the world, most commonly associated with quartz veins. The first step in extracting gold from these veins is to crush the rock and then pan it to remove any free-flowing gold. Once the panning process has separated out as much free-gold as possible, the next step is to use a sluice box or other type of device to separate out the heavier particles containing more gold.
These particles are then collected and sent off for further processing. The final step in gold mining is to smelt the gold ore down into pure bars of 24 karat bullion. This can be done at home with a small furnace, but most miners prefer to have their ore smelted by a professional service due to the hazardous nature of mercury fumes produced during this process.
How Does Gold Mining Work?
What is Called Gold Mine?
A gold mine is an excavation where gold is extracted from the earth. This can be done through open-pit mining or underground mining. Gold mines are often located in areas where there is a high concentration of the metal, such as in Africa, Australia, and Brazil.
Gold has been mined since ancient times and was one of the first metals used by humans. It has a long history in jewelry and coins and has also been used for its chemical properties in electronics and dentistry. Gold is abundant enough that it can be created into coins or jewelry without much effort, but it is rare enough so that it can only be produced selectively.
The price of gold fluctuates depending on supply and demand. It hit an all-time high in September 2020 due to economic uncertainties brought about by the COVID-19 pandemic.
How Does Gold Mining Make Money?
Gold mining is the process of extracting gold from underground mines. Gold is a valuable commodity, and as such, it has been mined for centuries. Today, gold mining is a large industry with thousands of miners working across the globe.
There are two main ways that gold miners make money: through the sale of gold bullion, and through the production of royalties and fees. Bullion sales are the primary source of revenue for most gold miners. Gold bullion is simply unrefined gold that has been extracted from the ground.
It is then sold to refineries, who refine it into pure gold bars or coins. These refined products are then sold to investors and central banks around the world. Royalties and fees are another important source of revenue for gold miners.
When a miner extracts gold from a mine, they typically have to pay a royalty to the owner of the land where the mine is located.
Is Gold Mining Safe?
Gold mining is often portrayed as a dirty and dangerous industry, with miners working in difficult and sometimes dangerous conditions. However, modern gold mining practices have much-improved safety for workers and the environment. One of the biggest dangers in gold mining is cave-ins.
Cave-ins are caused by unsupported roofs collapsing into the mine shaft. In order to prevent cave-ins, miners today use a variety of support systems including steel beams, wood timbers and concrete pillars. These support systems help to keep the roof of the mine stable and prevent it from collapsing.
Another danger in gold mining is exposure to poisonous chemicals. In the past, mercury was commonly used to extract gold from ore but this process released large amounts of mercury into the environment. Today, more environmentally friendly methods such as cyanide leaching are used to extract gold from ore but these processes still come with some risks.
To reduce these risks, modern mines have strict safety protocols in place such as using closed loop systems that capture and recycle cyanide before it can escape into the environment. Overall, gold mining today is much safer than it was in the past thanks to advances in technology and improved safety protocols. However, there are still some risks associated with this industry that miners need to be aware of and take precautions against.
Goldmine Or Gold Mine
Whether you’re a small-scale prospector or a large-scale mining operation, there’s no denying that finding gold is a risky business. But for those willing to take the gamble, there’s no doubt that striking it rich can be immensely rewarding.
Of course, as with any venture, there are also plenty of risks involved in gold mining.
From financial concerns and environmental hazards to injuries and even death, there are many potential dangers that come with the territory. So, is gold mining worth the risk? That’s ultimately for each individual to decide.
But if you’re feeling lucky and are up for an adventure, then it just might be worth your while to give it a shot!

Mining for gold is an ancient practice that has been done throughout the world for centuries. Today, gold mining is still a popular activity in many countries and is often done as a recreational activity.
People who enjoy gold mining typically do it as a hobby or to supplement their income. In addition to finding gold, people who mine for gold often find other precious metals and gemstones. There are many different ways to mine for gold, including panning, sluicing, dredging, and hard rock mining.
Each method has its own set of challenges and rewards. Gold miners must be careful not to damage the environment while mining for gold. Some methods of mining can be very destructive to the landscape and water sources.
Gold mining is generally safe for the miners if proper safety precautions are followed. However, there are some risks involved in any type of mining, including exposure to hazardous materials and dangerous working conditions.
Gold Mining Methods 1850S
Gold mining during the 1850s was very different to today’s modern day mining. In fact, most gold mined during the 1850s was alluvial gold, found in creek beds, or in the ground after a thunderstorm. This type of gold was relatively easy to mine as it didn’t require any specialised equipment or knowledge.
The main methods used to extract alluvial gold were panning and cradling. Panning involved using a circular dish (the pan) to swirl water around and hopefully wash away enough dirt and gravel to reveal some nuggets of gold amongst the contents. The problem with this method is that it’s very labour intensive and only really suitable for small-scale miners.
Cradling was a bit like panning on a larger scale. It involved using a wooden box (the cradle) which had a series of metal screens inside it. Miners would fill the cradle with dirt from the creek bed and then use water to wash it over the screens which trapped any heavier materials like stones or nuggets of gold whilst allowing lighter materials to pass through.
Again, this method was quite labour intensive but could be more effective than panning if there were enough people working together. During the 1850s, new technologies began to be developed which changed the face of Gold Mining forever. Sluices and Long Toms became popular ways of extracting alluvial gold as they were much faster than either hand-panning or cradling techniques.
A sluice consisted of a long wooden trough which had raised ridges running along its length inside – these ridges acted like riffles in a stream and helped catch any heavy materials like stones or pieces of gold whilst allowing lighter materials to flow through unharmed. Water was pumped into one end of the sluice so that it flowed down towards miners at the other end who collected anything caught by the riffles – again, this process required many workers but could produce good results if enough people were available..
Long Toms were similar in concept to sluices but instead relied on gravity alone rather than water pumps to help move material through them – they were essentially just an inclined plane covered in riffles over which dirt and gravel could be fed manually by shovel.. Although more efficient than previous methods, both sluices and long tom operations tended to lose around 20% of their potential yield due largely to inefficient riffle designs.
Gold mining is the process of extracting gold from the ground. Gold is a valuable commodity that has been used for centuries to make coins, jewelry, and other objects. The modern day gold rush began in 1848 when gold was discovered in California.
Since then, there have been many gold rushes around the world as people seek out this precious metal. Gold mining can be done by individuals, groups, or companies on a large scale. It is a dangerous profession because of the potential for cave-ins and toxic chemicals used in the process.


Characteristics and applications of L-type slurry pumps
Posted by Laura Shi (10 items)
The transmission part of the L-type slurry pump includes a bracket and a bearing assembly. The bearing assembly adopts an internationally leading cylindrical structure, which is convenient for adjusting the gap between the impeller and the front guard plate. It can be disassembled as a whole during maintenance, which is simple and convenient. The pump shaft has a large diameter, good rigidity, short cantilever, and will not bend or vibrate under harsh working conditions. The bearings use heavy-duty single-row or double-row tapered roller bearings and cylindrical roller bearings according to the transmitted power, which can withstand the large load of the pump. For axial and radial loads, the bearings are lubricated with grease. Both ends of the bearing body are equipped with sealed end caps, labyrinth sleeves and labyrinth rings, which can effectively prevent dirt such as slurry from entering the bearing, ensuring safe operation of the bearing and a high lifespan.

The spiral sand water separator is installed with an inclination of 20°-30°.
sand-water mixed material enters the water tank from the inlet pipe, and the particles with larger specific gravity (such as sand grains) in the mixed liquid are deposited on the bottom of the spiral groove due to the drop of self-weight surface.
Under the urging of the screw, the material is lifted along the bottom of the inclined U-shaped groove, and after leaving the liquid surface, it continues to move a certain distance.
The water in the sand gradually flows back into the water tank in the gap in the spiral groove.
The sand also gradually dries at the discharge port and falls on other conveying devices depending on its own weight. The supernatant is continuously drained from the drain to achieve sand separation.
● Compact structure, Small area coverage, Less investment.
● Economic, low maintenance cost.
● High efficiency in sand removal.
● Corrosion resistant material, strong equipment patience.
● Easy operation
★ Yangzhou Ryde keeps the rigfht to optimize and change the parameters.
★ For detailed product information, you can contact us directly.
The spiral sand water separator is widely used for urban guest house, mineral factory, and water treatment project pretreatment process.

For rock drilling and rock socketing, Bermingham has a wide variety of equipment available for sale or rent. Berminghammer reverse circulation drilling equipment is suited to all rock drilling methodologies; conventional rotary, down-the-hole hammer or cluster drill.
The BHD line of Reverse Circulation Drills were developed in-house by a joint effort of Bermingham’s Construction and Equipment Manufacturing Groups. It is well suited for rock drilling up to 2.5 meters in diameter and pairs seamlessly with Bermingham’s industry tested lead systems.
To understand the advantage of reverse circulation drilling one must understand that direct circulation is limited because the method simply lets water and cuttings come to the surface and spill over the side of the pile free flow to the lowest point in the area.
The main advantage of RC Drilling in foundation work is having control output of the spoils (cuttings). This is done by forcing the cuttings back up the inner tube of the drill string and out the top of the drill through discharge hose to the desired disposal location.
- Congested jobsites – Allows the contractor to direct all the cuttings into settling containers that can then be removed from the site
- Environmentally sensitive areas - With RC drilling you eliminate the damage to the surrounding area by directing the spoils into one spot (ideally a container)

25.3 Metallurgical Processes
In this section, we look at several processes.
The first step in processing metal-Containing ores is crushing.
Magnets can separate minerals if they are magnetic.
polar minerals can be separated from nonpolar gangue by static forces.
Sometimes solutions separate the minerals from the gangue.
The air forms bubbles and a froth.
The minerals are attached to the wet agent and can be collected.
The solution is separated by the gangue.
The minerals attach to the froth in a bubbled solution with the help of a wet agent.
Different techniques can be used to achieve this separation.
Different heating conditions affect the mineral.
Section 3.5 states that hydrated compounds can drive off water.
It is important to roast sulfide ores.
The ores are heated in the presence of oxygen to convert the sulfide into oxide and sulfur dioxide.
In some cases, a flux must be added to the mixture to separate the two materials.
The liquid metal and liquid slag have different densities.
The more dense liquid can flow out of the lower tap holes and the less dense liquid can flow out of the higher tap holes.
A hydrometallurgy process is used.
Small particles of gold are mixed with other substances.
Many streams and rivers have been contaminated with cyanide due to the practice of quenching.
New alternatives using the thiosulfate ion are being investigated.
Acid, base, and salt solutions can be used to separate metal-bearing minerals.
Under high pressure, the bauxite is heated in a concentrated NaOH solution.
Reduction of the aluminum out of the aluminum oxide is done by lysis.
The electrolysis is not carried out on molten Al2O3 because it is at a high temperature.
In the Hall process, the Al2O3 is dissolved into molten cryolite (Na3AlF6) and graphite rods are used to carry out the electrolysis in the liquid mixture.
The dissolved oxygen ion in the molten salt oxidizes the carbon that composes the electrodes.
Reducing agents are achieved by the use of graphite electrodes.
The refining of copper is an example of metallurgy.
The CuFeS2 is the most abundant copper source.
The chalcopyrite is roasted to convert it to CuS.
The iron forms oxides and sulfides.
The iron silicate is removed after it is formed.
The metal is not very pure because it reacts with oxygen to form sulfur dioxide gas and copper metal.
The copper is refined using lysis.
The copper is refined.
Pure metal is formed on the cathode.
The anode and the cathode are made of copper in the cell used to refine copper.
The impure copper needs to be refined, and the thin sheet of pure copper is the cathode.
As the current flows through the cell, the copper from the anode oxidizes and is dissolved in a copper sulfate solution.
It goes out as pure copper.
Even though the more active metals oxidize from the anode, they stay in solution and do not plate out on the cathode, because the copper anode is separate from the copper during electrolysis.
The less active metals do not oxidize and fall to the bottom of the cell as the copper is dissolved.
The sludge at the bottom of the cell contains precious metals.
About 25% of the silver produced in the US is recovered from the copper refining process.
Under high pressures, metal particles are pressed together to form a component.
The metal particles are fused together at a temperature high enough to strengthen them and increase their density.
Iron powder from mill scrap was once used in powder metallurgy.
The iron oxide in the scrap would fall off as it was being processed.
The iron oxide dust was heated in a hydrogen atmosphere.
Water atomization, a new method for the development of powdered metal, was introduced in the 1960s by the A. O. Smith Company.
The molten metal is melted and a small stream of liquid is allowed to flow from the bottom of the container.
A high-pressure blast of cold water breaks a stream of metal into small droplets that quickly solidify.
The metal products made in this way are more dense and smooth than the sponge powder made by powder metallurgy.
Many copper, bronze, carbide, and brass parts are made with powder metallurgy processes.
The part can be pressed directly into the desired shape, so waste is almost eliminated.
The press can be designed with intricate teeth on gears and multiple holes.

The Pro Camel 24 by Camel Mining is the big brother of the Desert Fox Gold Wheel and is the largest 12 volt automatic gold panning machine manufactured anywhere. It is a fast, high capacity machine capable of processing up to 400 pounds of placer sand per hour! This gold mining machine is for the miner who wants to process a lot of concentrates in a short time.
The Pro Camel 24" Gold Wheel has been recently redesigned to make it easier to work with. It has new legs that raise it up higher and the tailing bucket is now attached to the frame.
Why Does The Pro-Camel Automatic Gold Panning Machine Work So Well?
The Pro-Camel Automatic Gold Panning Machine uses the same basic technology of gold separation as a traditional gold pan: Water, Motion, & Gravity. Because gold is so much heavier than the other material that it’s found with, it can be easily separated from like sized material.
With a traditional gold pan, you create a slurry of water and material mixing it well to allow the gold to drop down to the bottom of the pan. You then slowly & carefully wash off the lighter material by dipping the edge of the pan in the water.
The same basic principles are being applied with the Pro-Camel, but much faster and more efficiently than panning by hand.
Pro-Camel RunningThe Pro-Camel’s Aqua-Jet provides an ample water supply to the edge and bottom of the spiral wheel to create the slurry needed to allow the gold to separate from the other material. As it does, the gold is scooped up in the 15 spiral riffles and stays there because of the deep “V” design. As the wheel turns, the spray bar rinses the lighter material away allowing the gold to ride up the spirals. When the gold drops into the second stage, any material tagging along for the ride is washed away allowing the clean gold to be deposited through the center hole of the wheel and into the gold catch cup hanging on the back of the machine.
The Pro-Camel 18 is also available for only $695. Select from the drop downs at the top of the page.

The Queen Louise Adit Complex, Poland
The revitalisation of the Queen Louise Adit mining complex has been a long-term process. It was carried out by the Coal Mining Museum in Zabrze, which owns and operates the complex, in close cooperation with local and regional authorities. The main aim of this challenging project was to preserve the mining heritage of the region by adapting and revitalizing the area for cultural, educational and tourism purposes. The project was funded with grants from the European Union, from the Municipality of Zabrze, the Province of Silesia, the National Environmental Protection Fund as well as with funds from the Coal Mining Museum in Zabrze.
The Queen Louise mine was the first Prussian state coal mine in Upper Silesia and was opened in 1791. Thanks to its activity, the town of Zabrze was transformed from a small settlement into a large city. The Queen Louise mine is of unique significance in the history of industrial development in Silesia and in Europe. The jury noted that “coal mining sites such as this one are in decline. Maintaining the heritage of historic coal mines is vital for future generations as it is an important element of the history of not only Poland but also of Europe. The large-scale mining machinery is now presented and interpreted as part of a museum experience.”
The vast post-mining infrastructure was restored and adapted to new functions. The whole project took almost 15 years to complete. It involved the revitalisation of both the ground infrastructure, comprising approximately 30 buildings dating from the 19th century, and the conservation of the more than 5 kilometres of underground corridors that connect them. The restoration of the mines has eliminated the harmful emissions generated by the historic mining practices, making the infrastructure safe for tourists and cultural activities. Three visitor centres have also been adapted from the existing buildings or newly built and include interpretive exhibits and artefacts which illustrate the history of the site. The jury also noted the range of expertise that was sought during the restoration project stating that “the restoration work required, and mobilised, the special knowledge of coal miners to make the site visitable.”


The New Elk Coal Mine reception and kickoff (Wednesday, July 7th at Mt. Carmel in Trinidad, CO) might sound like a casual affair, but it was not. With colorful and informative posters, Mark Gray, Owner, Amon Mahon, CEO, JD Morris, Safety Director converse with local job seekers, City and County officials and coal mining aficionados.
“The New Elk Mine comprises around 656Mt of hard coking coal, is permitted for production, is fully constructed, and is located 850 miles by rail to the Bay of Houston, and the Pasadena Deep Water Coal Terminal in the Gulf of Mexico. From there, they have shipping access to Europe, South America and Asia.”
Allegiance also owns the Lorencito Property, which neighbors the Mine, and comprises another 88Mt of hard coking coal. Combined, the New Elk Mine and the Lorencito Property comprise 744Mt of coal resources of which 45.1Mt have been converted from just three of nine coal seams representing just 31% of total coal resources, into coal reserves.” (Allegiance Coal Archives)

NMDC Ltd., a government-owned enterprise, is India’s single largest producer of iron ore. This navaratna company is fully under the administrative control of the Ministry of Steel. Its principal operations include the running of three iron-ore mines at Kirandul and Bacheli in Chhattisgarh, Donimalai in Karnataka; and one diamond mine at Panna.
Sources of moat
Large reserves of high-grade iron ore. The company has access to large proven and probable reserves of high grade iron-ore, consisting principally of hematite ore with a ferrous content greater than 64 per cent. Greater the ferrous content of iron-ore, the more sought after it is in steel manufacturing. Its high grade ore quality gives NMDC a strong competitive advantage and helps it command premium pricing and strong customer loyalty.
India’s largest iron ore producer. NMDC is the largest producer of iron ore by volume, producing around 13 per cent of the country’s iron ore output. It produced 2.38 crore tonnes of iron ore in FY10. Being such a large producer puts it in a strong negotiating position vis-à-vis buyers.
Low-cost producer. The company’s cost of production compares favourably with that of the world’s leading iron ore producers. It is seeking to further lower its costs across all its operations. Some of the factors that contribute to the company’s low cost of production include the mechanisation of its mines, continuous focus on reducing cost of mining, seeking improvements in operational efficiency, including logistics, and its access to a large and inexpensive pool of labour and talent in India.
In-house exploration capability. The company possesses strong in-house capability for undertaking exploration aimed at expanding its reserves. It is also using this capability to try and diversify into the production of other minerals besides iron ore. The company has a large research and development centre at Hyderabad which is capable of taking up assignments in the field of iron ore beneficiation and mineral processing.
What could cause moat to be breached
Rise in input costs. The company’s competitiveness and long-term profitability in large measure depend on its ability to maintain a low-cost base, including low labour and transport costs.
In recent times, the company has incurred increased insurance cost as a result of increased terror threats from Naxalites and other insurgent groups operating around its mines and areas of operation. Its labour cost has increased significantly over the last two years, partly due to increased competition for skilled labour. Therefore, any increase in input costs could have an adverse effect on the company’s business and could reduce its cost competitiveness.
Intense competition. The company’s business depends upon obtaining and maintaining leases to mining sites, some of which are in the process of renewal. Intense competition from the private sector in securing fresh mining leases could affect the company’s profitability and operating margins.
Ability to access mineral reserves. With the passage of time, mineral reserves decline. The company’s future results and margins will depend upon its ability to access mineral reserves with geological characteristics that allow mining at competitive costs. Replacement reserves may not be available when required. If available, they may not be of a quality capable of being mined at costs comparable to that incurred in mining from earlier mines.
Moreover, the company may err in assessing accurately the geological characteristics of any reserves that it acquires. This could lead to a situation where the company’s existing iron ore reserves cannot be mined at competitive costs.
Expiration of contracts. The company generates a significant portion of its revenue from certain key customers. In particular, Rashtriya Ispat Nigam Limited (VSP) and Essar Steel Limited together accounted for 37 per cent and 39 per cent respectively of revenues from the sale of iron ore in FY09. The company generally enters into five-year contracts with its customers. Many of the current agreements for exports, for instance, are due to expire in 2011. Although the company has entered into long-term contracts with certain key customers, there is always the risk that the counterparties to such contracts may not fulfil their contractual obligations or that on expiration these contracts may not be renewed.
Price volatility. Selling price and volume in the iron ore mining industry both depend on the prevailing and expected level of demand for iron ore in the global steel industry. The global steel industry is cyclical in nature. A number of factors influence the state of this industry, the most significant being the global demand for steel products. During periods of sluggish or declining regional or world economic growth, demand for steel products generally decreases. This leads to corresponding reduction in the demand for iron ore.
Prices of steel products are influenced by many factors, including demand, worldwide production capacity, capacity-utilisation rates, raw-material costs, exchange rates, trade barriers and improvements in steel-making processes. Accordingly, any significant decrease in either the demand or the price of steel products has the potential to affect both the demand and the price of iron ore. This would have an adverse effect on the company’s revenues.
Attacks by insurgent groups. Some of the company’s mining facilities are located in areas that are exposed to the risk of attacks by insurgent groups. Such attacks may disrupt its operations.
Inability to retain key personnel. The company is in particular dependent on the continued service and performance of its senior management team and other key team members in its business units. It does not maintain key man life insurance for certain of the senior members of its management team, its other directors, and other key personnel. Competition for senior management is intense in this industry and NMDC may not be able to retain senior management personnel or attract and retain new ones in future. These key team members possess technical and business capabilities that are hard to replace. The loss or diminution in the services of the company’s senior management or other key team members could have an adverse effect on the company’s business, operational results, and financial performance.
An iron ore producer like NMDC also faces the risk high inventory accumulation and difficulty in its disposal in times of suppressed demand.
NMDC proposes to augment production of iron ore from the current level of 30 million to 50 million tonnes by 2015. It has also chalked out plans for value addition by setting up pelletisation plants in Chhattisgarh and Karnataka, and setting up an integrated steel plant in Chhattisgarh. NMDC is also planning to venture into the mining of coal and other minerals.
NMDC is a zero-debt company. Over a span of five years, the free cash flow of the company has increased at a compounded annual growth rate (CAGR) of 21.96 per cent. During this period it has delivered a five-year average return on capital employed of 61.49 per cent and return on net worth of 40.67 per cent.
The stock is currently trading at a price-to-earnings ratio (P/E) of 12.93 which is much lower than its five-year median P/E of 24.57. Over the last five years its earnings per share has grown at a CAGR of 26.83 per cent, which translates into a price-earnings to growth (PEG) ratio of 0.48 times. An investor with a horizon of at least five years may invest in this resource-rich company.


The global steelmaker, the world’s largest by volume, announced it would invest heavily in mining and steelmaking in Mexico, where many U.S. automakers have been shifting small car production. Luxembourg-based ArcelorMittal, one of Northwest Indiana’s largest employers, plans to construct a new hot strip mill that will boost its productivity in Mexico from 4 million tons a year to 5.3 million tons a year.
ArcelorMittal recently invested $200 million in improvements at its Indiana Harbor steel mill, including upgrades to the “Mighty 80” 80-inch hot strip mill on the east side. But it also idled many finishing lines there, including the hot strip mill at the former LTV mill on the west side. The steelmaker accounts for about two-thirds of the 15 million tons of steel produced in Northwest Indiana annually.
