Rescue workers are working to reach 18 people who are trapped underground following a collapse of a gold mine in northwestern China’s Xinjiang region, state media reported.
A total of 40 people were working at the mine in Yining District, some 100 kilometers (60 miles) from the border with Kazakhstan when the mine collapsed on Saturday afternoon.
Twenty-two miners were brought to the surface, but 18 are still trapped.
“A rescue operation is underway to bring back the remaining miners,” Xinhua news agency said late on Saturday.
Mining safety has improved in China in recent decades, but in an industry where safety instructions are often lax, accidents are still common, particularly at the most rudimentary sites.
In September last year, 19 miners stranded underground following the collapse of a coal mine in northwestern Qinghai province were found dead after a lengthy search.
In December 2021, 20 miners were rescued from a flooded coal mine in northern Shanxi province, and two more died.
China is the world’s largest producer of gold. Last year, the country mined 370 tons of gold and has held its top position for more than 10 years.


New Sensor Can Detect Valuable Rare Earth Element in Waste Sources

Low concentrations of terbium could be identified from acid mine drainage and other waste sources.
A new luminescent sensor can detect terbium, a valuable rare earth element, from complex environmental samples like acid mine waste. The sensor, developed by researchers at Penn State, takes advantage of a protein that very specifically binds to rare earth elements and could be harnessed to help develop a domestic supply of these metals, which are used in technologies such as smart phones, electric car batteries, and energy efficient lighting. A paper describing the sensor was published in the Journal of the American Chemical Society.
Terbium, one of the rarest of the rare earth elements, produces the green color in cell phone displays and is also used in high-efficiency lighting and solid-state devices. However, there are a variety of chemical, environmental and political challenges to obtaining terbium and other rare earth elements from the environment. Developing new sources of these metals also requires robust detection methods, which poses another challenge. For example, the gold standard method of detecting rare earth elements in a sample — a type of mass spectrometry called ICP-MS — is expensive and not portable. Portable methods, however, are not as sensitive and do not perform well in complex environmental samples, where acidic conditions and other metals can interfere with detection.
“There is not currently a domestic supply chain of rare earth elements like terbium, but they are actually quite abundant in nontraditional sources in the U.S., including coal byproducts, acid mine drainage, and electronic waste,” said Joseph Cotruvo Jr., assistant professor and Louis Martarano Career Development Professor of Chemistry at Penn State, a member of the University’s Center for Critical Minerals, and senior author of the study. “In this study, we developed a luminescence-based sensor that can be used to detect and even quantify low concentrations of terbium in complex acidic samples.”

Efficient Silica Dust Monitoring Project
EnviroScience Solutions was engaged to undertake personal respirable, inhalable and crystalline silica dust assessments for a large quarry operation across NSW. The dust assessments form part of the client’s yearly obligations to comply with safety regulations for workers’ health and exposure levels.
John of EnviroScience said, “the health and safety of employees on site is the number one priority, and it is important that staff and management both understand the risks that we can unintentionally put ourselves at on a day-to-day basis. Dust exposure is a real issue and people need to be more aware of the health implications and pathways that this can occur”.
EnviroScience Solutions worked with the client to ensure the most suitable and standard day of operation was picked to replicate the full operational capabilities of each quarry and the potential exposure to respirable, inhalable and crystalline silica dust that employees could be exposed to. The assessment was conducted over an 8-hour period to replicate a standard working day and commenced at the start of shift. Prior to pumps and sampling heads being installed on employees, a general toolbox meeting was held to explain why the assessment was being conducted, the benefits, what was being assessed and what was required from the employees throughout the assessment. Once the pumps had been set up, EnviroScience personnel noted the environmental conditions on the day, as these could directly affect the movement and creation of dust. To gain a better understanding of the site, EnviroScience conducted a visual assessment of the site to identify key areas where excessive dust could be created by specific machinery, potentially posing a risk of exposure to employees.
Delivery of this project demonstrates EnviroScience Solutions’ mindset for maintaining a safe working environment for employees and consistently trying to improve working procedures for companies by providing ongoing site-specific recommendations.


Canada’s Cline Mining Corp. wants to develop an open-pit mine requiring roads, rock dumps, a coal washing plant, a power-line corridor, a mine camp and fuel storage.
Montana Gov. Brian Schweitzer and others have expressed concern the mine would pollute water in the Flathead River system, which spans the British Columbia-Montana border. The Flathead’s North Fork forms the western boundary of Glacier Park, and Flathead water flows into Montana’s sprawling Flathead Lake. Critics of the mine say it threatens wildlife habitat, as well.

West Virginia has rare opportunity in rare earth minerals | Opinion
If you have recently tried to buy a new or used car, you have been directly confronted with the global shortage of semiconductor chips.
When the pandemic hit last year, there was a surge in demand for chips to power computers, phones and other consumer electronics. The tokens were diverted to meet demand. Now that the demand for durable goods is increasing, the chip shortage is hitting the auto industry hard.
Chips are made from rare earth minerals, which are made up of 17 elements sharing similar chemical properties that give them the ability to discharge and accept electrons.
They are not uncommon, as they are abundant in the earth’s crust. However, rare earth elements are generally not found in concentrated amounts, so they are difficult to extract by traditional extraction methods.
What West Virginia may not realize is that the solid-state chip crisis points to a rare opportunity for our state.
Researchers at the West Virginia Water Research Institute (WVWRI), a program of the Energy Institute at WVU, are working to turn the acid mine drainage from coal mining into a rare earth mining resource. They recently received a continuation of a $ 2.1 million contract for their work from the National Energy Technology Laboratory (NETL).
In an interview with WVU Today, Paul Ziemkiewicz, director of WVWRI, said they have partnered with the West Virginia Department of Environmental Protection to build a pilot plant that will treat acid mine drainage to address the drinking water standards.
The technology will allow the extraction of one tonne per year of concentrate of rare earths and critical minerals. In addition, they are conducting a study for NETL on how to develop a national supply chain of factories in coal and metal mining areas on the basis of technology.
The factories could create significant skilled jobs and potentially produce at least 400 tonnes of rare earth elements each year.
In the United States, approximately 11,000 metric tonnes of rare earth elements are used each year in the manufacture of high-tech products, from fighter jets to cell phones.
The US Department of Energy estimates that the current global market for rare earth elements of $ 5 billion will grow by 40% over the next five years. According to the International Energy Agency, we extract about 13 percent of the rare earth elements here in the United States, China extract 60 percent, and Myanmar 11 percent.
The second part of the supply chain is processing. China processes 87% of the world’s rare earth elements and mineral concentrates. China has used its advantages in both extraction and processing to control prices and supply, leading to significant volatility and disagreements with other countries. It is time to break this monopoly.
Fortunately, countries around the world are working to develop new supply chains for rare earth elements. In the United States, the United States Department of Energy, through the Democratic and Republican administrations, has allocated millions of dollars to fund research into the extraction, processing and support of an American market for rare earth elements.
The Biden administration and the US Congress reinforce this important commitment. Real opportunities are there for us to create a better future for West Virginia to stay, rebuild and succeed.
We all hope the pandemic is a once in a lifetime event, but we can’t count on it. It’s time for America to start doing things again. For too long we have relied on the ingenuity of other countries. We cannot ignore the peril in which we place the United States without better control of our manufacturing supply chains. It is essential that we put aside our political differences to help our state and our country prosper.
I recently had the opportunity to join other lawmakers in a meeting with US Secretary of Energy Jennifer Granholm and US Senator Joe Manchin.
Secretary Granholm said West Virginia has been left behind, but better days are ahead. She underscored President Biden’s commitment to our state. Helping West Virginia seize this rare opportunity to play a pivotal role in the future of rare earth elements is a good start to that promise.
Senator Glenn Jeffries represents the 8th Senate District of the West Virginia State Senate. He is the president of Cornerstone Interiors and lives at Red House.

- Challenges facing Madagascar's mining sector
Nickel, cobalt and rare earths sourced from Madagascar
Madagascar boasts a plethora of valuable minerals that are now crucial in modern times. Subterranean deposits within the island encompass an array of precious minerals, including:
- Nickel is a versatile metal that is commonly used in the production of stainless steel. It's also a crucial component in the manufacturing of high-powered Lithium-ion batteries, which are commonly found in electric vehicles and other high-capacity energy storage devices.
- Cobalt plays a critical role in the manufacturing of rechargeable batteries for our electronic devices, as well as in the production of metal alloys and industrial chemistry.
- Titanium - a versatile material widely utilized in aeronautics, aerospace, and medical industries.
- Rare metals that play vital roles in the production of electronics, military gear, and sustainable technologies are called rare earths. Although they are often combined with other minerals, these components are referred to as rare earths because they occur naturally in limited quantities. For example, neodymium, which is found in Madagascar, allows for the creation of high-quality permanent magnets required for wind turbines and electric vehicle motors.
- Uranium is commonly utilized as fuel in nuclear reactors.
- List of valuable minerals includes graphite, chromium, zircon, rutile, and vanadium…
To demonstrate Madagascar's significance in the production of crucial minerals for the energy transition, it should be highlighted that the island ranks as the 6th largest global supplier of rare earth minerals, surpassing major producers such as Brazil, Russia, and India.
Mining actors identified in Madagascar
Madagascar's mining sector has been magnetizing numerous international industrial groups since the 1990s, when it underwent liberalization. At present, the key players in the sector are:
- Ambatovy is a nickel and cobalt mine situated on the east coast of Madagascar. It is operated by a joint venture between Sumitomo Corporation, Sherritt International, and Korea Resources Corporation.
- QMM is a mine located in southern Madagascar, rich in minerals such as ilmenite, zircon, and rutile. This renowned mine is operated by Rio Tinto, a multinational mining company with a strong presence in the international market. Ambodilafa - This is a vanadium and titanium project located in southwestern Madagascar. The project is operated by the Australian company Neometals.
Madagascar's mining sector: Valuable assets for development
Madagascar is a desirable location for international investors seeking to develop its abundant mineral resources. Some of the island's key assets that make it an attractive destination for mining include:
- The abundance and variety of ore deposits in the area ensure a secure and sustainable investment for our resources.
- Essential Minerals for Energy and Electronics in High Demand for Future Strategies
- Accessing Local Labour Made Easy
- The proximity to Africa allows for easy access to essential materials and industrial equipment.
- Environmental and social regulations that enable the implementation of large-scale industrial projects.
Challenges facing Madagascar's mining sector
Although Madagascar's mining industry has the potential to benefit local communities and the environment, significant hurdles must be overcome to achieve this. Here are the key challenges that manufacturers in Madagascar must address in order to transition towards sustainable mining practices.
- Restrict the practice of employing children in mining.
- Enhance the education and training of young people.
- Disrupt the skillsets of the nearby workforce.
- Enhance vital infrastructure by developing energy, transport, and drinking water systems.
- To decarbonize their energy production, companies can choose between gas-fired power plants or renewable energies.
- Enhance the consideration of environmental impacts associated with mining activities. This includes effects on flora, fauna, natural habitats, underwater life, and pollution through harmful emissions.
- Industry professionals should consider shifting towards Green Nickel production as it can significantly enhance production processes and improve working conditions.
Easy Skill has extensive experience working on mining projects in Madagascar, and we understand the unique challenges faced by industrialists in this region. As a result, we have established a permanent team on the island to specifically assist large mining groups with their operations.

Copper mine productivity from Renaissance to now
Mining productivity has always been important. I am sure that the Egyptians or Romans were thinking about it as much as we do these days. However, since numerical data processing came into existence only recently, they never had the opportunity to have a long term view on it. This has clearly changed, even if data on Roman or Egyptian mines is probably too far fetched to ask for. So lets concentrate on times were there is a little more evidence, such as the last 500 years.
Before we do so though, lets first define mining productivity as how many pounds of copper were produced per miner and year. This ratio requires of course two inputs, data for annual production for a mine or district on the one hand, and employment data of miners on the other. Data on production exists more or less since kings and queens always wanted to know how much taxes they are owed. However, information on how many miners worked the mines is more incidental, and also hampered with more uncertainty. One has to rely on a lot of anecdotal evidence and generalizations; especially the further back one goes. However, there is a body of research that can be drawn on. Nowadays the data is slightly more accessible, but it is difficult at times to separate pure employees from contractors. If I had the chance I used the former. In addition, lets assume that the most productive mines throughout history were also the most efficient. After all, only when one can produce lots of metal at a low price, can one push out higher cost competitors and dominate the market. This is especially the case when looking at the metal markets some hundred years ago, when they were relatively small compared to nowadays. Finally, lets make sure it is understood that this little story is not an all-explaining one. It is rather a little scratch on the surface and is very much a work in progress.
With all this in mind, lets look what picture emerges since the year 1520. Productivities were pretty low then, so lets use the log scale, first.
The chart starts during the height of the Renaissance. It was a time that probably saw some of the most significant innovations since the collapse of the Roman Empire. The rediscovery of classic Greek and Arab writings brought a lot of technical knowledge to Europe, especially that of water wheels. Their adoption for water pumping, hoisting and ore crushing helped to transform mining in Central Europe immensely. One example of an important copper mining center back then was the Mansfeld district in Germany, where thin seems of Kupferschiefer (copper slate) were mined. Production rates during the 1500s were little over 1000 lb per miner and year, and were falling as time progressed and deeper ore was developed.
German mining knowledge was instrumental in the development of the next major copper deposit at Falun, Sweden. The mines were thrice as productive as the ones in Germany, and so it was just a matter of time that they became the dominant copper suppliers in Europe. The gathered riches fueled Swedens territorial expansion during much of the 17th century. At some point Sweden had so much copper that it even became a store of wealth and currency.
The mid 1600s also saw a major innovation with the testing of gunpowder as a blasting agent. However, even while it improved productivity in rock breaking, the adoption of it was slow. After all, it was dangerous to handle and the explosive residues did not help the air quality in the poorly vented mine workings. In any case, knowledge of mining copper spread further north to Norway around Trondheim (Lokken and Roros), which became an important copper mining province. Productivities however did not come close to the ones in Sweden, earlier. Nevertheless, Norway’s copper was of higher quality than Sweden’s and commanded higher prices in the ports of Europe.
With the advent of the industrial revolution, Great Britain was at the forefront of innovation. The invention of the steam engine was essential to be able to reach previously inaccessible ore sections by draining deeper mine levels. The copper (and tin) deposits in Cornwall benefited from this game changing invention very much. Subsequently the region became an important European source for copper.
However, copper was still mainly mined in vein deposits that required lots of labor. After all, even with steam engines, productivity growth without versatile mobile mechanization, was very difficult to achieve in underground settings. Miners still followed veins to extract the ore, and the most powerful mobile entity down below was still the horse. Steam engines were simply too bulky and heavy to help the miner extracting the ore itself.
The solution to that was to move above ground and start mining deposits in open pit mines. The stars were aligned when in the late 1800s innovations such as dynamite, rock drills, and the first steam shovels came together. This all combined with the maturing rail technology allowed to mine ore deposits that were deemed exhausted or too low grade, before. One of these mines was the British development Minera Rio Tinto in southern Spain. The company re-developed the old mine workings that the Romans and even Phoenicians worked before. The productivity gains were impressive. The copper produced per miner jumped by a factor of 10 compared to the mines in Cornwall some 50 years before. This mine was so successful that it laid the foundation for one of the biggest mining enterprise ever since, bearing the same name Rio Tinto.
However, it was for the Americans to take over the torch of innovation and push mine productivity to new levels. The ingenuity of the young nation did not know any bounds. Inventions such as steam shovels, electricity, rock drills, froth floatation, cheap explosives (Anfo), solvent extraction, heap leaching and larger mining trucks, all hailed from this still very young nation. It transformed mining in various ways, but the ultimate result was always an increase in mine productivity.
The results started to show, when mining of the “Richest Hill on Earth” began in Butte, Montana. During its heydays, the mine was already twice as productive as Rio Tinto in Spain. While Butte was running at capacity, some straddlers of the Klondike Gold Rush discovered the rich Kennecott deposit. Its development entailed lots of innovation, such as electric power and energy recuperation, as well as the use of ammonia leach, roller mills and flotation circuits. The development of the massive Bingham Canyon mine was the next major step. It more than doubled productivity once again and stayed the most productive mine for much of the 20th century. However, even Bingham Canyon is past its prime now, with Escondida wearing the crown of highest productivity. In 2017 it produced more than 300,000 lb (almost 140 tonnes) per miner.
Switching the chart back to normal scale, a striking observation can be made. Productivity growth has been linear since the days of the Rio Tinto mine. In fact the trajectory gives me quite a funny feeling, and reminds me of such relationships as Moore’s Law for the number of transistors used in CPUs (which predicts an exponential not linear relationship, though).
From a little under 13,000 lb per miner at Rio Tinto in 1888 to more than 305,000 lb per miner at Escondida as of 2017 – it is a constant and impressive upward march. For the last 140 years, the productivity growth seems to be unabated with every miner able to add about 2300 lb per year. Again, this is only valid for the most efficient mines out there, but the continuity of this trend for almost one and a half centuries is truly mind-boggling. This is even more so the case when reminding ourselves of the ever-decreasing ore grades around the world. To stay on this path we need even more ore processing, ie. bigger mills and tailing dams on the one hand, but also more automation on the other, ie. autonomous trucks, shovels, processing and sorting, transportation. No matter how we look at it, the task copper miners face seems herculean.
In summary, for four centuries after the height of the Renaissance copper mine productivities were very low. They ranged between less than 500 to up to 3000 lb/miner and year. The rates however were more a function of the easy access to rich lodes of metal close to the surface and above the water table. It took the convergence of technical innovations at the end of the 1800s to substantially change the productivity trajectory in copper mining. Only then was the mining of ore bodies that were considered uneconomical even shortly before possible. Subsequently, productivity rates grew by magnitudes and and sit now at about 300,000 lb per miner and year. The seen linear relationship of productivity gains over time is impressive and it will need much more innovation to keep the growth that way for another 140 years. By then 600,000 lb per miner and year (~270 tonnes) could be produced by the most efficient mine. Stepping back for a moment, one can wonder on how the miner of the future will look like. Will it be a computer geek bringing home a huge copper nugget from outer space, all while staying at her mega yacht in downtown Vancouver?

Kolkata: Mining major Coal India suffered losses to the tune of Rs 700 crore in the April-June quarter owing to a sharp rise in diesel prices, a top company official said.
In the quarter (under review), we lost about Rs 700 crore as diesel prices increased by about 35 per cent. It was in the range of Rs 66-67 and now at around Rs 89. This has been a substantial rise, Coal India Chairman Pramod Agarwal said during a recent earnings conference call.
The state-run miner has been drawing up plans to replace its diesel-run heavy machinery with LNG-fired equipment, and adding 1,500 electric vehicles to its fleet in the next five years to support carbon emission cuts.
CIL has envisaged creating a carbon offset of around 2.5 lakh tonnes over the next five years, the Kolkata-headquartered company said.
It has also taken initiatives for a pilot project in collaboration with GAIL (India) Ltd in some mining sites before starting bulk use of LNG.
Agarwal had also said the costs of Coal India have gone up and there is no reason that the mining behemoth should not increase price of the dry fuel.


ArcelorMittal Nippon Steel India takes over Bhander Power Plant
A natural gas-based thermal plant with an installed capacity of 500MW
ArcelorMittal Nippon Steel India (AM/NS India) has completed the acquisition of Bhander Power Plant in Hazira, Gujarat from Edelweiss Asset Reconstruction Company. Bhander, a natural gas-based thermal plant with an installed capacity of 500MW, will remain captive to AM/NS India’s steel manufacturing operations at Hazira.
Bhander, which was commissioned in 2006 and commenced commercial operations in 2008, was purchased by AM/NS India under the Securitisation and Reconstruction of Financial Assets and Enforcement of Securities Interest (SARFAESI) Act.
Earlier this month, ArcelorMittal India (AMIPL) was selected preferred bidder for an iron ore mine license in Odisha following an auction process facilitated by the state government. Thakurani block in the district of Keonjhar, with estimated reserves of 179.26 million tonnes, is expected to make a valuable contribution to AM/NS India’s long-term raw material requirements. On conclusion of the license award process, AMIPL will proceed to seek requisite clearances, as well as mine development and production agreements, ahead of commencing mining operations.
Commenting, Dilip Oommen, CEO of AM/NS India, said: “We are pleased to have acquired these important ancillary assets for our steelmaking facilities. This is in line with an intent to secure a robust captive power and commodity supply chain as we continue to make strong strides in our production and operational performance. Efforts to become increasingly self-reliant, in this case through the procurement of a key energy source in Gujarat and an iron ore rich reserve in Odisha, form part of AM/NS India’s medium to long term strategy to significantly grow our production capacity in India.”

On the other hand, on July 19, the transportation company Aymaraes SAC approved the operational study of the AMG Peru project to connect the “El Santo” mine to the Caylloma electrical substation, located 6 km from the factory.
From the beginning of May to the end of June 2022, a trench exploration campaign was carried out on the “Couriège” and “Renaissance” permits, in order to test the promising prospects located in the main axes of interest highlighted by the bells. geophysics (induced polarization and magnetometry) for 2020 and 2021. Fourteen trenches were opened, for a total of 725 meters and 712 samples. 695 samples were analyzed by the approved laboratory of Filab Paramaribo (Suriname) and 17 by the Company’s laboratory located in “Dieu Merci”. The positive results of this trench exploration campaign confirm the economic potential of the “César” zone demonstrated by the 2021 core drilling campaign. In the so-called “Lupé” zone, intense illegal gold panning has revealed a massive vein . All the samples taken showed a general average of 11.06 g/t, which confirms the high gold potential of the area.
The positive results of this trench exploration campaign confirm the economic potential of the “César” zone demonstrated by the 2021 core drilling campaign.

The process is performed/done/executed with precoat filtration in combination with activated carbon treatment Sulphurnet offer various executions for a high-efficiency filtration process as well as an effective activated carbon addition with efficient usage of the carbon.


- Hundreds of years of copper mining
- Norway ranked in top 10 for mining jurisdictions
- No significant exploration in districts for more than 20 years
- Strategic acquisition of exploration rights over two claims containing Joma copper-zinc mine
- Joint venture with Panoramic Resources involving the Sulitjelma Project
Highly prospective claims over significant copper-zinc mines
|Coverage||50km² (including the historic Gjersvik mine and Exploration and Exploitation (Mining) Agreement over the Joma mine)|
Drake Resources acquired important exploration rights in July 2012 to some 100 square kilometres of highly prospective copper and zinc ground in the Grong District in Norway, known as the Gjersvik Project.
The Joma Naeringspark licences encompass the Joma mine and its prospective westerly and southerly strike extensions. A total of 11.5 million tonnes was mined at Joma from 1972 to 1998 at a grade of 1.49 per cent copper and 1.45 per cent zinc. Considerable copper-zinc mineralisation remains at the mine. The licences include the Gjersvik deposit where 450,000 tonnes of ore grading 2.15 per cent copper and 0.6 per cent zinc was mined from 1994 to 1998.
The company finds this project particularly attractive as the rights are located in a proven and significant mining area, are close to infrastructure and have not had the benefit of modern exploration technologies.
The Joma mine sits within the Leipikvattnet nappe which is composed of three major greenstone units comprising basalt and pillow lavas intercalated with quartzitic and graphitic phyllites. The greenstones are named (from northeast to southwest), the outer, middle and inner greenstones. The mineralisation is hosted within the middle greenstone unit. The metamorphic grade is upper greenschist facies.
The Gjersvik project is hosted by metabasalts of the Gjersvik nappe which is structurally above the Leipikvattnet nappe
SULITJELMA JOINT VENTURE
Area of significant historical copper production
|Ownership||Joint Venture Agreement, Drake 30%|
|Coverage||~74km² at Sulitjelma|
December 2011: Drake expanded its Norway landholding in the major copper mining district of Sulitjelma. The area has had significant historical copper production of 25 million tonnes of ore containing 1.8% copper, 0.86% zinc, 10 g/t silver and 0.25 g/t gold.
Massive sulphide mineralisation occurs at several locations within these permits and modern geophysics will identify areas where it may attain economic thicknesses.
A VTEM airborne electromagnetic survey completed in 2014 identified a number of interesting anomalies. Four targets of interest lie within the western thrust or Sydgruvefeltet ore field which is an area of known massive sulphide mineralisation mapped over a ~10km north / south direction and hosts the Sagmo (1.9Mt mined of 1.6% Cu and 0.23% Zn. Source Norwegian Geological Survey) and the Jakobsbakken (4.47Mt mined of 1.55% Cu and 2.42% Zn. Source Norwegian Geological Survey) historic orebodies. There is also a significant amount of historic exploration data to assist in selecting priority targets.
In the eastern Nordgruvefeltet region, an extensive conductive horizon with a strike length in excess of 5kms coincident with a copper / zinc bearing sulphide horizon is mapped. Two anomalies have been selected from this region.

Greenfield Massachusetts gold mining is one the staples of the gold industry and this is highly relevant as Greenfield MA gold mining is the root necessity for those who invest in gold. This is where the fruits of Greenfield Massachusetts gold mining are kept in a more raw or even bar form and bought and sold on the open market as an equity that has historically been known to grow and retain value far better than other investment options. Greenfield MA gold mining has been in existence for centuries and even to this day Greenfield Massachusetts gold mining is an integral part of the global economy.
There is another aspect to Greenfield MA gold mining and that is the gold extracted and harvested through Greenfield Massachusetts gold mining that is used for commercial and product purposes. The jeweler business is a large one and is also something that can bring in big business. It is through Greenfield MA gold mining that the gold is found and then turned in to those rings, necklaces and watches that are highly coveted by those who like good quality and precious metals.
Greenfield MA gold mining was once a much more dangerous industry and through newer technologies and processes it has gotten much safer. This is because Greenfield Massachusetts gold mining is like any other business and it uses a series of tools, techniques, equipment and programs to help make the Greenfield MA gold mining itself more productive and profitable. This is important as when Greenfield Massachusetts gold mining operations produce more the amount of gold available increases and this assists in the supply and demand concept that drives the price and popularity of gold as a precious metal.
Gold is priced, typically, per ounce as it is found in bits and clumps through Greenfield MA gold mining. This is why gold is one of the more expensive natural elements as one needs to dig deep via Greenfield Massachusetts gold mining to get the gold. It can also be found, at times and small amounts, through water Greenfield MA gold mining. There are various aspects to the Greenfield Massachusetts gold mining industry yet all have the same end result; the production of gold that is used in a variety of ways and means. People forget that gold is used in more than just jeweler as it can be incorporated in things such as dental fillings and even drill bits due to the various strengths of the types of gold that are determined based on composition and ranked and rated as a karat count.
The most widely used modern form of gold mining in Greenfield MA comes in hard rock mining. Rather than sifting through loose material, such as is used in panning, hard rock gold mining removes gold encased in rock. These operations can be done above ground or underground in shafts.
Open-pit mining, also known as strip mining, is often toted as more cost-effective way of gold mining in Greenfield Massachusetts and increases worker safety. Workers aren't exposed to the risk of a cave-in or closed quarters with toxic fumes. Also machinery isn't constricted, as it would in a mine shaft, therefore production is increased.

Global steam coal price forecast (February 2013)
Prices for steam coal in the global market demonstrate positive dynamics in January-February 2013. In particular, prices for Australian material (6,600 ccal/kg) hiked from $90/t to $97/t FOB Newcastle; Japanese consumers pay $107/t CFR East Coast.
At the moment, market researchers have different opinions on further development of the coal market (as well as raw material and steel product markets in general). Metal Expert Consulting offers its own vision of steam coal market until 2015, comparing it with consensus forecast of investment companies and analiticians.
Metal Expert Consulting applies a steam coal price forecast methodology based on mixed forecasting methods, including non-linear dynamics, global coal demand/supply models, assessment of costs of key suppliers. For more details on Metal Expert Consulting forecasting methods, as well as on investment forecasts for raw materials, see January report Global iron ore price forecast.
Several forecasts of steam coal price change prepared after the beginning of 2013 are provided below.
Global steam coal price forecasts by industrial and financial analiticians, $/t
The diagram below presents a comparison of Metal Expert Consulting forecast of export prices for Australian steam coal and price expectations of investment and industry analyticians adjusted to this basis.
Metal Expert Consulting’s quarterly forecast for 2013 is based on our know-how methodologies and non-linear dynamics methods. We expect that coking coal prices will hit this year’s ceiling in Q2, reflecting the consumer demand. In the future, the market will drift towards balance and prices will stabilize at around $100/t.
Metal Expert Consulting’s medium-term price forecast for steam coal differs considerably from consensus forecast of investment companies. We think the global market will move towards surplus in that period, because planned commissionings of coal mining projects will be ahead of the growth of consumers’ demand. Nevertheless, coal prices will be supported by high prices for hydrocarbons.
New suppliers with lower production costs (against average market level) and tougher competition in the global market for steam coal will push down profitability of leading suppliers and ensure yearly prices decrease to $85/t in long-term perspective.

Image of an Andalusian quarry
The Andalusian mining industry has all the elements needed to establish itself as a driving force of the regional economy over the next ten years
Andalusian mines are making an old dream come true: processing all minerals extracted at the Iberian Pyrite Belt in-house. There are currently five operational mines and additional projects for reopening Alquife, Aznalcóllar and Tharsis. The sector creates 10,000 direct jobs, 30,000 indirect and induced jobs, and generates a yearly business opportunities volume of €3.2 billion. The development of electric vehicles large renewable energy plants will increasingly require the use of copper, with the expansion of emergent countries such as India supporting long-term consumption. Market expansion will continue and Andalusia will be able to attract new international investment.
Together with companies operating in Andalusia, a group of small new companies funded via specialized Stock Markets (Toronto, London and Sidney) are currently assessing some areas of Andalusia. According to the Andalusian Mining Portal, the company CentrePeak Resources has projects in the Huelva locations of La Zarza and Riotinto, whereas Pan Global Resources, company based in Vancouver and listed in the Toronto Stock Market, is seeking copper in Escacena, near Aznalcollar. If an interesting site is found, it will make it available to the marketplace with the aim to find a larger investor. That is how this business cycle works.

Copper was the first metal to be smelted from its ore and the first to be cast into a shape using a mould. At present, however, most copper, both mined and recycled, goes into electronic devices owing to its high conductivity. There is more copper than any other metal in phones and computers – in fact it weighs more than all the other metals combined.
'Copper Country' is a series of three topographic drawings of the largest copper mines in the world, Bingham Canyon in the United States, and Chuquicamata and El Morro in Chile. The drawings are made by etching printed circuit boards (PCB) with ferric chloride (FeCl3), a technique normally used in making copper circuits for electronic appliances. The chemical process is interrupted and frozen with varnish, creating an unpredictable variation of the ‘natural’ background in contrast to the graphic human intervention of open-pit mineral mining.

PNG Mining History
Mining has been occurring in Papua New Guinea for about a century, mainly in specific gold fields such as Misima Island, Wau-Bulolo, Woodlark Island and Mt Kare (amongst others), but also as large scale modern mines since the 1972 development of the Panguna copper-gold-silver mine on Bougainville Island, the mid-1980s development of the Ok Tedi copper-gold-silver mine in Western Province, the Porgera gold mine in the Central Highlands in the mid-1990s, the Lihir gold mine in New Ireland in the late 1990s and more recently the Hidden Valley gold-silver mine in the late 2000s. Smaller gold mines include Tolukuma, Kainantu, Simberi and Sinivit, as well as major deposits being explored and considered for development at Frieda River, Wafi-Golpu and Yandera. The Ramu nickel-cobalt project (near Madang) was built in the late 2000s, and, after an unsuccessful legal case attempting to block the use of marine tailings disposal, began production in late 2012. A basic mining map of Papua New Guinea is shown in Figure 1. At the Panguna and Ok Tedi copper-gold-silver mines, mine tailings were directly discharged into an adjacent river system, while waste rock was either directly dumped to the river or placed on easily erodible dumps. The substantive scale of social and environmental impacts from the Panguna mine led to a civil war breaking out in May 1989 which lasted more than a decade (Havini & John, 2001), before peace was finally negotiated in 2002. Riverine mine waste disposal is still being used at Ok Tedi, Porgera and Tolukuma, which are all associated with severe environmental and social impacts along their respective river systems (especially the Fly River downstream from Ok Tedi; see Bolton, 2008 and papers therein; Tingay, 2007).
Alternatively, at the former Misima gold-silver mine on Misima Island east of Port Moresby, as well as at the operating gold mines of Simberi and Lihir, tailings are discharged to the sea at depths of ~100 metres or more. The Ramu nickel-cobalt project, near Madang, also now uses marine disposal of tailings and began production in late 2012 after the failure of a lengthy court case where the community sought to stop the use of marine tailings disposal. Ongoing concerns about impacts from marine tailings disposal at Basamuk Bay are regularly reported in PNG’s formal and social media (see PNG Mine Watch, 2014).
By the start of the new millennium, there was yet to be a major mine in Papua New Guinea which used conventional engineered mine waste management techniques, such as a tailings storage facility (or tailings dam) and careful waste rock dump designs to minimise erosion and environmental impacts. These approaches are required by law in countries such as Australia or Canada and are considered standard mining practice. Although the mid-2000s Kainantu gold mine built a tailings dam, though the dam was very modest in scale and not comparable in scale to Ok Tedi or other major mines. The 2013 and cumulative production from major mines across PNG are shown in Tables 1 and 2, along with reported mineral resources in Table 3. As can be observed, some projects such as Lihir and Ok Tedi remain large producers, while deposits such as Wafi-Golpu and Frieda River could be substantial new mines if they are successful in the assessment and approvals process and proceed to commercial production.
Mining in the Morobe Province
This section is summarised from Lowenstein (1982) and Enesar (2004), unless otherwise noted.
Gold was discovered in the Morobe Province in 1910 by Arthur Darling in the Bulolo River near Koranga Creek, although significant activity did not start until the site was re-located in 1922 by William Park and Jack Nettleton. The region was proclaimed a gold field in February 1923, with work focussed on alluvial gold in Koranga Creek and the Bulolo River. Interest continued to grow as rich deposits of alluvial gravels were discovered throughout the 1920s, and in 1927 the first hard rock or lode gold deposit was discovered at Edie Creek. By 1930, both alluvial dredging and hard rock mining was progressing to modest scale projects based on rich gold grades and easily mineable ore at or near the surface.
The Day Dawn hard rock mine at Edie Creek began production in May 1931, while the large scale Bulolo dredge began operations in March 1932. The major operations in the region concentrated on dredging in the Bulolo area and hard rock mining around the Edie Creek area throughout the 1930’s, with record field production in 1940 of 8,477 kilograms of gold and 6,025 kilograms of silver (about 272,500 ounces of gold and 193,700 ounces of silver). At its peak in 1941, the Bulolo dredge processed about 3 million tonnes of gravels per year and recovered some 5,200 kilograms of gold and 2,250 kilograms of silver – a yield of 0.22 grams of gold per tonne of gravel processed (silver yield was 0.098 g/t). The Koranga sluicing operation processed up to some 1 million tonnes per year of gravels at an approximate yield of about 0.09 g/t gold (silver yield was about 0.05 g/t). The outbreak of World War 2 and the advance of the Japanese military in the area closed the entire field in January 1942.
The Bulldog track from Upper Edie Creek to the Lakekamu gold field to the south was built by the army from 1942 to 1944 to help supply the war effort in the region. After a period of damage assessment and reestablishment of infrastructure, especially power supplies, dredging recommenced at Bulolo in February 1947 with hard rock mining re-starting at the Upper Ridges site in 1948. While dredging and hard rock mining returned to their previous production levels for the 1950’s, the field had begun to decline by 1960. The Bulolo dredge closed in 1967, and the Golden Peaks mine near Wau closed in 1977. Reported production over time is shown in Figure 2. The alluvial gold resources were considered to be depleted by the mid-1980’s, with attention turned to trying to revive the Edie Creek area (Neale, 1994) as well as develop the Hidden Valley/Kaveroi and Hamata deposits discovered in the mid-1980’s (see Pascoe, 1991; Denwer and Mowat, 1997).
After resuming production in 1947, the Bulolo dredge only processed about 1 to 2 million tonnes of gravels per year and recovered between 1,000 to 2,500 kilograms of gold per year and between 300 to 1,000 kilograms of silver per year – an average yield of 0.11 grams of gold per tonne of gravel processed (silver yield was 0.051 g/t). The Koranga sluicing operation continued processing at between 0.5 to 1 million tonnes per year of gravels at an approximate yield of about 0.09 g/t gold (silver yield was about 0.05 g/t), though post-war operations only lasted from 1952 to 1961.
Exploration activity in Morobe – Wafi-Golpu and beyond
While the Hidden Valley mine has impacted on the environment and communities there is also a genuine concern, if not fear, about further impacts from the mining. During the field visit for this project, MPI discovered that few people along the river had heard, let alone been consulted about the potential for further mining development in the region or Province. This is despite the raw prospectivity of the Province and the potential for mining to impact not just on communities where the mining occurs but on the Province as a whole as shown in Fig 16 and Table 11.
According to MMJV’s own presentation at the PNG Chamber of Mines and Petroleum Conference of 2013, the Morobe Province is highly prospective with a concentration of activity within 30km of Wafi and further exploration licenses along the Watut and Markam River regions. As well as the extent of potential mining activity there is also the issue of scale with Newcrest listing Wafi-Golpu as one of their ‘big three’ along with Lihir in PNG and Cadia Valley in Australia, at their AGM in September 2013.
To date, while there are extensive seabed exploration licenses in nearby West and East New Britain, New Ireland, Manus, Medang and Milne Bar Provinces, only one has been registered in the Morobe Province. There are, however, a number of predominantly terrestrial licenses that extend into the sea along the coast. While the seabed mining industry has yet to develop, an extension of exploration interest into Morobe waters could place additional development pressure on the Province.
