2019-8-18 · Uranium mining in Australia has been highly political, particularly for the Australian Labor Party(ALP) at both state and federal level. Development of projects has often been stymied by a succession of inquiries and the politicisation of the issuing of mining and export licences.
In 2015 Boss Resources Ltd based in Perth bought Uranium One Australia, which owned the mine and asociated deposits, for A$11.5 million in staged payments plus up to $3 million from operating cash flow. Boss formed a joint venture with Wattle Mining Pty Ltd (Boss 80% and Wattle 20%) to take over Uranium One Australia.
2019-8-20 · Mining in Australia has long been a significant primary industry and contributor to the Australian economy by providing export income, royalty payments and employment. Historically, mining booms have also encouraged population growth via immigration to Australia, particularly the gold rushes of the 1850s. Many different ores, gems and minerals
Uranium mining is the beginning of the nuclear chain. Industries such as nuclear power and the manufacturing of nuclear weapons would be impossible without a steady supply of uranium ore.

Frieda River Copper-Gold Project, Papua New Guinea (PanAust 80 per cent)
PanAust holds an 80 per cent interest in the Frieda River Copper-Gold Project in Papua New Guinea (PNG).
The Company completed a feasibility study for the Project in May 2016. In June the same year, PanAust submitted its application for a Special Mining Lease (SML) for the Project to the Papua New Guinean Mineral Resources Authority (MRA).
In May 2017, PanAust announced the completion of an addendum to the original feasibility study. The addendum incorporated data and technical analysis from geological, geotechnical and metallurgical field programs that was not available at the time of the feasibility study.
The Horse-Ivaal-Trukai, Ekwai and Koki (HITEK) global Mineral Resource is now estimated to contain 2.64 billion tonnes of mineralisation at an average grade of 0.44 per cent copper and 0.23g/t gold representing 12 million tonnes (Mt) of copper and 19 million ounces (Moz) of gold.
PanAust considers that the optimum approach to this substantial Mineral Resource is via a multi-staged development that involves an initial project stage that forms the platform for subsequent phases of exploration, Mineral Resource definition and development.
The feasibility study and addendum contemplates an initial Project based on the HITEK copper-gold porphyry deposits and comprises a large-scale, open-pit mining operation that supplies a conventional process plant with a nominal capacity of 40 million tonnes per annum (Mtpa). Average annual production of metal in concentrate is expected to be 175,000 tonnes copper and 250,000 ounces of gold. The initial mine life is estimated a 18 years with 714Mt of mill feed that includes 686Mt of Ore Reserve. The HITEK open-pit design is based exclusively on Measured and Indicated Mineral Resources and mill feed represents approximately a quarter of the global Mineral Resource. The Project will have a competitive C1 cost of US$0.69/lb copper (average over the life-of-mine) that will place it in within the first quartile of the global copper cost curve.
There are multiple pathways to further expand and extend the initial Project with potential development scenarios indicating that mill feed could be increased from 714Mt to 1,700Mt on currently known Mineral Resources. The HITEK deposits have not been closed off by drilling, and together with additional known deposits and exploration targets, offer considerable potential to increase the Mineral Resource base to support mine life extension and capital expansion. The nearby high-grade Nena epithermal copper-gold deposits offer further potential for subsequent development that leverages the infrastructure facilities identified in the feasibility study.
For further information about the Project, see PanAust's quarterly reports Company Announcements listed on the 'Company Announcement' page.

Ebba Busch, Sweden’s energy and industry minister, declared that the world’s most modern underground iron ore mine is being built in Kiruna, 150 kilometers north of the article circle.
The mine in Kiruna, northern Sweden, has the potential to lead Europe in the green transition, lower its carbon footprint, and increase competitiveness, according to Busch. It’s an ambitious target during the Swedish EU presidency.
“This transformation requires critical minerals. Furthermore, rare earth elements are needed for electric vehicles”, Busch was quoted by the EUObserver as saying.
She added that it is also a means of weaning Europe off of its reliance on China and other countries for rare earth metals and iron ore imports, noting that China produces roughly 70% of the metals required to support the green transition.
LKAB, a Swedish state firm that manages it, is making grand promises to supply Europe and the rest of the globe with raw materials needed to manufacture anything from electric automobiles to wind turbines.
The Swedish mine contains:
- A deposit of 4 billion tonnes of minerals.
- Forcing the neighboring town of Kiruna and its residents to pick up and move 3 kilometers east.
- A process that will take years.
Jan Mostrom, president and CEO of LKAB stated on Thursday that they had discovered an additional one million tonnes of rare earth oxides, the largest known deposit in Europe, in a nearby area called Per Geijer.
Mostrom stated that the discovery is “completely critical for our transition from combustion engines to electric engines,” as the sale of electric vehicles in Europe is likely to expand. However, he also stated that because of the complexities of acquiring permissions, it could take 10 to 15 years before mining can start.
The mine is a troublesome lifeline for the residents of Kiruna, dominating the surrounding environment and posing an issue for traditional reindeer herding by the region’s Sami indigenous population. The Sami claim they will be forced to give up their ancestral land and traditions.
Around 23,000 people live in about 50 communities spread throughout a municipal territory the size of Slovenia.

Hello and welcome back to the website that steals millions of dollars worth of stock picks from expert stock pickers and gives them away for free.
Today's we will reveal a stock that Alex Koyfman wants to charge you $1,999 to learn about.
He claims in a new teaser to know a company that will save the electric vehicle industry and that will unlock 4.3 million tons of lithium from an oil field in Canada.
Alex left enough clues in the presentation for me to figure out the name of the company that he's teasing, and I will reveal it in the video below for free.
On top of that, I will also give you information on the stock so you can decide if it's worth investing in or not.
Also, don't forget to click the link under the video to check out the Insider Newsletter. This is my favorite stock picking service, and they consistently beat the market.
Let's get started now!
Transcript Of Video
First, let's start with the teaser and figure out what Alex is talking about.
According to Alex, one of the biggest lithium resources on the planet—big enough to supply global demand for three years and worth an estimated $322 billion—has been sitting around for decades, in plain view, with nobody able to lay a finger on it.
According to Alex, the brine produced from oil drilling is loaded with lithium, and that brine might now be worth more than the oil itself.
Also, according to Alex, there's one company that can extract the lithium, which he refers to as black lithium, from this brine.
But that's not all that it can do.
You can already extract lithium from brine using evaporation ponds.
But this mystery company can do it without evaporation ponds, which makes the process 20 times faster.
Alex Is Pitching E3 Lithium
The company Alex is pitching is E3 Litihum.
E3 Lithium is a lithium resource and technology company headquartered in Alberta, Canada. The company's goal is to produce high purity, battery grade lithium products to power the growing electrical revolution.
E3 Lithium has the largest Measured & Indicated lithium resource in Canada, according to Natural Resources Canada data. The resource is located in the Leduc Aquifer, a world-class brine deposit in south-central Alberta. E3 Lithium is developing the Clearwater Project, which will extract lithium from the Leduc Aquifer using its proprietary Direct Lithium Extraction (DLE) technology.
DLE is a more sustainable and efficient way to extract lithium than traditional methods, such as brine pumping and evaporation. E3 Lithium's DLE technology uses an ion exchange process to extract lithium from the brine, leaving behind the impurities. This results in a high purity lithium concentrate that can be further processed to produce battery grade lithium products.
E3 Lithium's Clearwater Project is expected to produce over 200,000 tonnes of lithium carbonate equivalent per year. The project is in the early stages of development, but it has the potential to be a major supplier of lithium to the global market.
In addition to its lithium resource, E3 Lithium also has a number of other technologies that it is developing to improve the efficiency and sustainability of lithium extraction. These technologies include:
- A process to recover lithium from waste brines
- A process to extract lithium from clay deposits
- A process to produce lithium hydroxide, a high-purity lithium product that is used in batteries
E3 Lithium is well-positioned to be a leading supplier of lithium to the global market. The company has a large lithium resource, a proprietary DLE technology, and a number of other technologies that are being developed to improve the efficiency and sustainability of lithium extraction. E3 Lithium is also located in Alberta, Canada, which is a mining-friendly jurisdiction with a skilled workforce.

Leaky Feeder Cable for Underground Mining
Underground mining employs this cutting-edge technology. This is a cable that broadcasts radio waves throughout the mine and functions as an antenna. In comparison to traditional ways, this offers improved communication and protection. Minerals, cabling specialists, and manufacturers all benefit from these feeder cables because of this. Miners are safer and more efficient when they operate thanks to these feeders.
An Important Feature of a Mine Gas Detector
Mine gas detectors are a must for any worker working undermines. These detectors are very beneficial in determining the presence of combustible and poisonous gasses. And this in turn enables miners to take the required steps to prevent any potential harm. The following factors must be considered:-
- The sensors used must be compatible with the environment.
- Alarms and alerts are a must.
- These gas detectors must be user-friendly and easy to process.
- The material from which these detectors are manufactured should be durable.
- Connectivity is the most required thing in today’s digital age.
- These detectors should be flexible, i.e. they can work at different work sites.
- Live monitoring can make better decisions when it is to safety.
Hence, by considering these features, choosing a gas detector for underground mining can prove to be really helpful to miners.
Working in an Underground Mining
A critical process for extracting invaluable resources and vital minerals from the earth’s crust. The tunnels and shafts are excavated in this process and this makes miners access ore deposits located deep inside.
Well, underground mining can prove to be challenging and dangerous due to the use of specialized equipment, techniques, and safety protocols.
But, underground mining also comes with some dangers including air pollution, changes in water flow patterns and gas seepage into water and soil supplies both chemically and naturally.
Also, the collapse of mine props often causes accidents due to earthquakes. Additionally, if the ventilation system fails to remove exhaust from mining instruments, explosions may occur.
In conclusion, mining has become more efficient nowadays. And in the case of underground mining, is much less labour-intensive and only fewer people work below the surface. Fewer people are involved in working, fewer chances of people falling at risk. Having the correct mining equipment makes a huge difference between success and failure.
Hence, safety must always come first in the case of underground mining.

The 1st device is called longwall shearer. It is a mining machine, which works underground, in the so-called mining wall, or in the place where the coal is directly output. It moves using the special conveyor (called scrapers); it does not make use of caterpillars (such as boom-type roadheader). The CM user works such a device by the remote control. (see roof bolter)The 2nd equipment applied underground is called boom-type roadheader. It moves making use of caterpillars and works below ground where drills roadways in the mine. Its front side with the tool drills the stone and move ahead. The obtained coal is transferred at the bottom of the boom-type roadheader.The last device, which will be provided in this article, is known as coal crusher. It is an instrument used for crushing coals into smaller parts. Here are machines for crushing mineral coal and brown coal, too.

Flooding, fires, and gas often made mines too costly to maintain
whatcom historical society
Discovery of coal along the shore of Bellingham Bay in the early 1850s led to the development of mining as one of the city’s earliest commercial enterprises. Coal deposits located along the bluffs at the north edge of today’s Fairhaven were first noted by William Prattle in 1852, prior to any non-Indian settlement around Bellingham Bay.
Prattle had come from San Francisco to the San Juan Islands to cut timber for use in California’s building boom following the 1848 Gold Rush. While in the San Juans, Prattle heard native reports of coal around Bellingham Bay. With coal commanding a high price in San Francisco, and being eager to take advantage of an economic opportunity, Prattle decided to investigate these reports.
While exploring Bellingham Bay in October 1852, Prattle found promising coal deposits along the Fairhaven shore, near the present-day Chrysalis Inn & Spa on 10th Street. He then traveled to San Francisco to raise funds, and with two partners formed the Puget Sound Coal Mining Association.
Returning to Bellingham Bay in January 1853, Prattle and his partners staked claims to the shoreland area, which became known as Prattle’s Point. Prattle and his partners then leased the mining rights to other operators.
Mining activity at Prattle’s Point began in the fall of 1853, working a nearly vertical 8-foot seam of coal. After being dug by hand, the coal was carried by wheelbarrow to the shore and loaded on ships for transport to San Francisco.
Prattle’s mine, however, was not large enough to achieve commercial success, and operation gradually was reduced over the next few years. Discouraged by these events, Prattle seems to have lost interest and abandoned his claim in 1859. About 150 tons of coal were shipped before the mine closed permanently. Prattle went on to become an election judge and road inspector for the county.
As the Prattle mine was opening in the fall of 1853, another coal deposit was discovered to the north of Prattle’s Point on the bluff below the west end of present day Laurel Street. This 17-foot thick vein was found by two employees of Henry Roeder, who had established the first settlement on Bellingham Bay and opened a lumber mill at the mouth of Whatcom Creek in December of 1852.
Roeder, who owned the Sehome Hill property on which the vein was discovered, immediately saw an opportunity for financial profit from the coal. His first move was to have 60 tons of coal extracted from the seam, and shipped as a sample to San Francisco. After the coal sold for $16 per ton, Roeder then sold his coal-bearing land for $18,000 to a group of San Francisco investors who organized the Bellingham Bay Coal Company and made Edmund Fitzhugh the mine’s first local manager.
Development of the Sehome mine proceeded slowly for several years until 1859, when the owners decided to invest $100,000 in improving the shaft and constructing related facilities such as a wharf, coal bunkers, and a tramway from the mine to the bunkers. In order to provide for dependable transport of their coal to San Francisco, the company purchased three ships, The Amethyst, the Lookout, and the Germania.
Bellingham Bay Coal Company’s Sehome mine proved to be quite successful, generating a gross income of $300,000 for its owners in its first year of operation. Its success attracted competition from Charles Richards, a local merchant, who formed the Union Coal Company, to attempt to re-open mining near Prattle’s original efforts.
A small community named Unionville formed around Richards’ project.
Consisting of a 100-foot vertical shaft, Union’s mine operated for only two years, shipping a total of 2,500 tons of coal to San Francisco.
Coal at the Sehome mine was dug by hand in the shaft and brought to the entrance in groups of seven to nine coal cars, pulled by mules and horses. Each car could carry one and a half tons. When the mine was operating at full capacity, the coal trains made 9 trips a day to the entrance.
As the mine’s shaft went deeper and closer to tide level, problems developed from seepage and flooding. Fire also was a constant worry as the coal being mined had a high sulfur content and was highly combustible when wet. When the coal ignited, the shafts were flooded and then subsequently had to be pumped out at a high cost to continue mining. Toxic gas collection inside the tunnels also was a continuing hazard.
Despite these problems, the Sehome mine continued to operate, employing as many as 100 workers, including many immigrants from England, Wales and China. The Bellingham Bay Coal Company in 1863 brought in a new manager, Michael Padden, with a background in mining in Pennsylvania and the Seattle area. Padden eventually homesteaded in Happy Valley and was the discoverer of Lake Padden, to which he gave his name.
A major expansion of the Sehome mine was undertaken in March 1875, with the opening of new shaft higher up on the hill, just south of today’s Morse Condominiums. This new shaft ran northeast under Railroad Avenue and eventually would reach a depth of 500 feet, and also extend at least 500 feet out under the bay.
Problems with flooding and gas continued to beset the mine, and in 1876, major flooding occurred in the mine’s lower levels. The deeper tunnels were then abandoned in favor of digging coal about 150 feet higher.
The increasing expenses of dealing with fire, gas, and flooding dramatically reduced the profitability of the Sehome mine. Bellingham Bay Coal Company’s President Pierre Cornwall traveled to Bellingham from San Francisco in 1877 with a geologist and a coal mining expert to inspect the mine. Cornwall’s team decided that continued mining was unfeasible, and work at the mine came to a halt in December.
The end for the Sehome mine came in January 1878, when the coal company sold all the mining equipment, keeping only the property. Shipment of the remaining 4,000 tons of coal in the bunkers to San Francisco was completed in February 1878.
Bellingham Bay Coal Company vacant property on the side of Sehome Hill was moved into Pierre Cornwall’s Bellingham Bay Improvement Company’s extensive holdings that would be developed in the 1880s and 1890s into modern Bellingham. Cornwall’s Bellingham Bay & British Columbia Railroad, completed between Bellingham and Sumas in 1891, constructed its locomotive roundhouse at the site of the Sehome mine. This structure remained in place behind Morse Steel through the early 1980s when rail service on the line was terminated. The mine’s location at the south end of Railroad Avenue is now being developed for residential condominiums.
