The Places visited in the Story
The Gold Mine
Welsh gold has been mined since at least the Bronze Age, and the purity of the gold has added an extra reason for its extraction. The Romans certainly valued it above other sources of gold perhaps because it often has a reddish tint in comparison to gold extracted elsewhere. This is due to the fact that the gold is stained by copper which lies in the rock next to the veins of gold.
Although there is no evidence for gold mining taking place at Coed-y-Brenin in the time of Rhiannon and Geraint there are certainly rich veins of gold here, and gold would have been visible in the rivers and streams.
The Gwynfynydd Gold Mine closed in the late 1990s although there are often rumours about it reopening due to the increase in the value of gold. The last gold mine to operate was the Dolaucothi Gold Mines near Pumpsaint which is also a listed ancient monument and now in the care of the National Trust and billed as a quirky visitor attraction


China iron ore imports jump 19%; Demand firm
China’s iron ore imports rose in March from
relatively low levels a year earlier, customs data showed on Tuesday, with
demand for the steelmaking ingredient underpinned by robust industrial
“Iron ore imports just returned to a normal level
from a relatively low base last year when shipments were affected by extreme
weather in Australia and Brazil,” said Cai Biyu, analyst with GF Futures.
The world’s biggest iron ore consumer brought in
102.11 million tonnes of the raw material last month, according to data from
the General Administration of Customs, up 18.9% from March 2020.
In the first quarter, China imported 283.44 million
tonnes of iron ore, up from 263 million tonnes over the same period last year.
Demand for iron ore has been supported by robust
steel consumption in the construction and manufacturing sectors.
Steel futures prices have surged to record highs of
over 5,000 yuan ($763.58) per tonne and prompting demand for iron ore.
“Despite production curbs in Tangshan, mills in
other places could replenish stocks on peak season demand,” said Cai.
The customs data also showed that China exported
7.54 million tonnes of steel products and brought in 1.32 million tonnes last month.
In the first quarter, China’s steel exports rose
23.8% from a year earlier to 17.68 million tonnes.
Steel imports in the first three months of the year
increased 17% on an annual basis to 3.72 million tonnes, according to the

With the signing of Critical Mineral partnership agreement between India-Australia, India has embarked to make itself immune from supply shocks and promote domestic mining of minerals like lithium, cobalt and nickel which have applications in industries ranging from automobile, defense, nuclear energy and electronics. It will
help India in installing 175GW of renewable energy capacity
by FY2022 and further expand it to 500 GW by 2030. India being the second
largest market in Asia for new solar PV
capacity (13 GW) and fourth for total
installation (60.4 GW) in FY 2021 will be requiring minerals to scale up its capacity addition. In an effort to attain self-reliance in critical and strategic minerals, Khanij Bidesh Ltd is mandated to acquire mineral mines in South America which has got some of the largest reserves of lithium globally, for instance Chile has 9200 MT and Argentina has 2200 MT of lithium reserves.
Also, India has set to move towards full electric mobility by FY2030 which will be a major driver among others. By signing of various MOUs with foreign governments, India is looking to be a major player in critical mineral sector. Critical minerals will be playing a major role in India’s clean energy transition and help in meeting the objective of making India net zero emitter by 2070 & cutting carbon emission by 33-35%by 2050.

The relationship between magnets and mining is much l […]
The relationship between magnets and mining is much larger than it might seem at first glance. First, because many magnetic components or non-magnetic but magnetized components used to make household and industrial magnets are extracted by the mining industry, and then processed and processed until the magnets are configured as they are. The final version.
Extract minerals via magnet
However, this is not the only relationship between these magnets and the mining industry. Therefore, it must be borne in mind that when extracting minerals (such as coal), various machines and mechanical equipment are used in the extraction process, usually using electrical energy and electronic components for operation, and the mechanical devices of these components are equipped with magnets.
In addition, the machinery used in the mining industry must be protected from the magnetic materials present in the mining mineral layer on a regular basis. Therefore, if the machine is not properly protected by placing defensive magnets when mining coal in the mine, the magnetic minerals present in the coal may eventually cause some type of damage to the machine and the machine. Of course, its presence will contaminate the material being extracted.
This type of magnetic material is called "contaminated ferrous metal material" in the mining industry, and has the particularity that it can damage the machine and significantly shorten its service life. However, a magnetic strip can be installed in the machine to protect the machine dedicated to mining activities.
Magnet for mineral cleaning
In addition, once the aggregate is extracted, another application of magnets in the mining industry will enter during the processing of raw materials. Therefore, for example, in the case of coal, such coal extracted in mining activities must be washed and processed in order to be useful and effective as a combustible material. Although other purification technologies such as coal washing do come into play, the action of magnets along the conveyor belt can remove the magnetic charge of coal or any other raw material extracted from the mine and materials that may contaminate its magnetic source.
These magnetic materials present in aggregates transported by conveyor belts in the mining industry can be extracted and separated by magnets (such as IMA OV-E), which remove magnetic parts from the equipment and keep them clean, or for example by magnetic plate fins Responsible for performing the same types of activities, not only in the mining industry, but also in the food industry used in similar ways.
Therefore, as we have seen, the manufacturing of magnets and magnetic materials is not only extracted from the earth through the mining industry, but they also play a very important role in the extraction of any other minerals, not only protecting the machine that extracts it, but also in the entire The process continues to play a role, so that the extracted raw materials are not affected by any magnetic materials that may contaminate it.

Operations expected to resume after K2 mine fire
Published Tuesday, January 29, 2013 12:03AM CST
Last Updated Tuesday, January 29, 2013 4:33PM CST
Operations were expected to resume Tuesday afternoon following a fire at a potash mine in eastern Saskatchewan.
The fire at Mosaic’s K2 potash mine near Esterhazy started Monday morning, sending 318 miners to underground refuge stations where they waited for hours as emergency crews put out the blaze and the heavy smoke cleared.
A spokesperson for Mosaic says the rescue efforts wrapped up around midnight and no injuries have been reported.
The company’s K1 mine resumed production Tuesday and K2 was expected to be back in operation later in the day.
A piece of mobile mining equipment is believed to be the source of the blaze.
The last underground fire that forced an evacuation at the Esterhazy mine occurred in 2006.

US Gold Corp. (NASDAQ: USAU) (âUS Goldâ or the âCompanyâ), a gold exploration and development company, is pleased to provide an update on its CK gold project located in Southeast Wyoming. The Company has seen significant activity at the CK Gold Project over the summer, which currently continues in the fall of 2021, and plans to advance the project until a clearance and development decision is made on an accelerated basis. Here are the highlights of recent activities:
- Following the study of the site’s wetlands, the CK gold project received a non-jurisdictional decision from the US Army Corps of Engineers.
- Signed land and right-of-way agreement ensuring the project’s footprint and access to private and state lands (no federal land is involved).
- Extensive local engagement and a new project-specific website, located at www.ckgoldmine.com, was launched.
- Pre-feasibility study (“PFS”) expected by the end of 2021, being optimized.
- Advance the Feasibility Study (âFSâ) fieldwork, building on the ESP for the planned completion of the FS by mid-2022.
- Continuous monitoring of the baseline environment for the potential filing of a mining permit application in 2022.
Kevin Francis, vice president of exploration and technical services for US Gold Corp. said, âWe are currently on track to complete our CK Gold Project PFS by the end of the year. By design, we went well beyond what would normally be required for a PFS so that we could move on to FS-level project appraisal by mid-2022. Our field and field studies labs are designed to fill any gaps in the PFS, which will allow us to move seamlessly towards a full feasibility study. continue to collect the additional data needed at the project site during the summer and fall 2021 field season, which is expected to end in November. Basic environmental monitoring continues, having started in September 2020, with the goal of being able to submit an application permit to the state of Wyoming once a development decision has been made. Although a development decision depends on many factors, we are very encouraged by what we have seen.
In February 2021, the Company received a notice from the US Army Corps of Engineers that the CK Gold Project footprint, as described in the submission, is not jurisdictional for United States of America waters. This means that the only regulatory authority for the project is the State of Wyoming. Wyoming has extensive experience in the extractive industries and management of the Company believes this determination gives the project a potentially faster route to approval.
Summary of the land agreement
In September 2021, US Gold announced that it had signed a land agreement with a local rancher to secure an option to lease additional land and a permanent right of way to support operations should the project move to development and production. . The new agreement allows for an additional access road into the project off County Road 210, approximately two miles from the paved Happy Jack Road to the west. This will reduce approximately 2.5 miles of travel on County Road 210 to reach the CK Gold Project location from the causeway.
Project website summary
A new CK Gold project specific website has been created and serves to inform local stakeholders and investors of project specific developments and potential operating methods. The site is accessible at the address www.ckgoldmine.com. In addition, outreach to state and local officials, local authorities, chambers, immediate neighbors covered more than 44 separate meetings reaching over 120 people since February 2021 explaining aspects of the project including the potential, l employment, investment, taxes and royalties, and the relatively simple, clean nature of the project.
Update of the pre-feasibility study
The Company continues to optimize several PFS inputs. With Kevin Francis joining the management of the Company, a new independent qualified person has been recruited for the modeling and calculation of PFS resources. Additional engineering studies are underway, aiming to optimize the processing rate up to 20,000 tonnes per day. In addition, concepts for the beneficial use of the site rock and the post-exploitation use of the site are under consideration. Management now expects the PFS to be released in the fourth quarter of 2021.
Summary of the 2021 field program
The PFS was designed for the rapid development of the project. Therefore, field activities progressing this summer and fall at the CK Gold Project are aimed at allowing the project to evolve towards a full FS in 2022. Highlights include:
- Up to 3 drilling rigs on the project, covering site geotechnics (foundations), pit geotechnics (stability), hydrology and improved water monitoring.
- Plan to drill a total of 47 holes in 2021, some of which could extend the resource beyond FS data capture.
- Drilling fills in the gaps and reduces uncertainty in hydrology, geotechnics, geochemistry, engineering, resource expansion and mine planning.
- Discovery of an enriched chalcopyrite / pyrite sulphide zone in hole CK-21 within the current resource, potentially improving contained copper values. (See the photo of the kernel in photo 1 below).
- The beneficial use of the mined non-mineralized ore offers a significant potential benefit to the project. Market and engineering studies are underway to investigate the potential value of the project rock as an aggregate. The benefits include additional revenue for the project, royalties to the state, and a source of rock that has already been mined that will have a lower carbon footprint, displacing other mined rock specifically for aggregate.
- Studies are continuing to assess the viability of long-term water storage in the completed surface mine, addressing the provision of greater storage capacity at little or no cost to local taxpayers.
Photo 1 shows an interval of CK21-01c which intersected a sulphide zone of 245 ft to 254 ft. At about 250 ft, we estimated the total sulphides to be about 10 to 25% of the total rock. The sulphides are mainly chalcopyrite (CuFeS2, 34.5% Cu) on pyrite with about 75% chalcopyrite to 25% pyrite and higher proportions of chalcopyrite in some areas. The rock type harboring massive sulphides is a weak mylonite with some silicification and weak phyllic alteration. There is an important system of vertical fractures directly under the sulphides with moderate potassium and phyllic alteration which increases in intensity from the sulphide zone. In general, gold and copper mineralization at CK Gold is widely disseminated, so the company is encouraged by the semi-massive sulphide zone.
The 2020 and 2021 drilling programs include viewer surveys of geotechnical core holes and surface mapping. The data generated from this work allowed the development of a more sophisticated fault model for the CK Gold deposit. The importance of these faults is to form hard boundaries to the gold-copper mineralization, as well as lithological alteration boundaries and to determine the hydrological properties of the rock mass, which without faults is nearly impermeable. Perhaps the most important is the verification of the position of the Copper King fault on the east side of the deposit, forming a clear and hard boundary to gold-copper mineralization. Whether this fault is post-mineral or syn-mineral and grade control remains to be determined, requiring drilling beneath the White River post-mineral formation southeast of known mineralization. Photo 2 shows the sunrise at the CK Gold project with the wind farm in the background.
Quality assurance and quality control procedure (“QA / CQ”)
US Gold employs a rigorous QA / QC protocol on all aspects of the sampling and analysis procedure. The drill core is checked, recorded, marked for sampling and sawn in half. Half of each drill core is kept for future reference and the other half of each drill core is sent to ALS, an ISO 17025 accredited laboratory in Elko, Nevada to complete all sample preparation and analysis. Samples are analyzed by fire assay with atomic absorption finish for gold and four-acid ICP-MS analysis for silver and copper. For QA / QC purposes, certified standards, blank samples and duplicate samples are inserted into the sample stream. US Gold Corp. Also periodically submits pulp samples to another independent laboratory for control analysis.
Note on the qualified person
This statement has been reviewed by Kevin Francis, P Geo, SME Registered Member, Vice President – Exploration and Technical Services of US Gold, who has inspected the data provided in this announcement and is aware of the activities described in the Project Update CK Gold. Acting within the framework of his expertise, Mr. Francis, as a qualified person, has examined the information provided and finds it accurate and reflecting the facts.


Description Of Mineral Hammer Crusher:
Mineral Hammer Crusher is composed of rack, rotor, sieve bar, hammer, etc. Motordrives rotor through transmission belt, and materials are crushed due to the collision between hammer and materials produced by the rotation of rotor.
Application Of Mineral Hammer Crusher:
Mineral Hammer Crusher is suitable for crushing materials such as coal, gypsum, alum,and limestone. The compressive strength of materials is no more than 1000 kg/cm2, and the humidity is no more than 15%.
How does a Mineral Hammer Crusher work?
Mineral Hammer crusher mainly breaks materials by the impact of hammers. After that, the material smaller than the gap of the grate screen is discharged, and the material with larger particle size is bounced back to the lining plate and crushed by the additional impact of the hammers.

High Pressure Grinding Rolls (HPGR) were introduced as a new grinding technology in 1984. Since then, they have been successfully installed in a large number of plants throughout the world, mainly for cement and limestone. More recently, HPGRs have also been applied in mineral processing plants, largely in iron ore and diamond treatment. In these industries, the application of HPGR ranges from coarse grinding, e.g. the grinding of 65mm (2.5") size excess pebbles in AG circulation loops, to final grinding of <100μm material to high Blaine values in the preparation of pellet feed.

Gahcho Kué Diamond Mine Surpassed 5M-Carat Output In October
The Gahcho Kué Diamond mine in Canada’s Northwestern Territories, produced more than 5 million carats by early October. The mine, 51 percent owned by De Beers, with Mountain Province Diamonds owning the rest, declared commercial production in March and has been projected to produce an average of 4.5-million carats a year.
Mine General Manager Allan Rodel attributed the great output to a higher-than-expected recovered diamond grade of 2.07 carats per tonne of ore through the first nine months of this year. The higher grade, along with swift and efficient work identifying and removing bottlenecks in the process plant, has allowed for a greater throughput.
Gahcho Kué’s production now accounts for a significant portion of De Beers’ global production portfolio and is credited with having boosted the group’s rough diamond output over the first three quarter of 2017.

Wolframite, (Fe,Mn)WO4, is an iron manganese tungstate mineral that is the intermediate between ferberite (Fe2+ rich) and hübnerite (Mn2+ rich). Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives. Associated minerals include cassiterite, scheelite, bismuth, quartz, pyrite, galena, sphalerite, and arsenopyrite.
This mineral was historically found in Europe in Bohemia, Saxony, and Cornwall. China reportedly has the world’s largest supply of tungsten ore with about 60%. Other producers are Canada, Portugal, Russia, Australia, Thailand, South Korea, Rwanda, Bolivia, the United States, and the Democratic Republic of the Congo and recently found in Nigeria.
Extraction of tungsten from wolframite ore.
Wolframite is highly valued as the main source of the metal tungsten, a strong and quite dense material with a high melting temperature used for electric filaments and armor-piercing ammunition, as well as hard tungsten carbide machine tools. During World War II, wolframite mines were a strategic asset, due to its use in munitions and tools.

GMC is a large mining company led by Lady Helen Hawk and it's tough mercenary miners. We do it all we mine, we transport, we build and we kill. We are unlike other mining companies; who often strip planets of their resources for the purposes of their own greed and wealth. Some of GMC's major terrestrial operations include those on Sumitra and Brak.
Galacian Mining Corporation is one of the oldest and richest mining companies in the galaxy and they didn't get that way by letting others compete with them. Miners who get in their way tend to die and we will eliminate any competition at all costs.
GMC can go toe to toe with any mining company out in the galaxy today, being backed up by the Commonality, it has numerous ships to transport any raw material in a decent amount of time. All our pilots go thru a rigorous training to maximize time and efficiency.
Founded in Year 10 Day 56, the Galacian Mining Corporation established their first base of operation in the Jinet System, Brak Sector, lead by Nara Pong. Starting off as a small company based on a single planet, GMC has been able to thrive on the system's natural resources and establish a solid trade for raw materials in the Brak sector.
During Year 10 Day 350, Marcus Blackheart was introduced as the new CEO for Galacian Mining Corporation. Under his rule, he made sure every single Station was fully loaded with the Raw Materials needed to make the massive Modular Taskforce Cruiser that the Commonality had designs for.
In Year 11 Day 220, Marcus Blackheart stepped down as leader of GMC and turned the reigns over to Lady Helen Hawk. An honest and experienced leader. In her desire to make GMC one of the best mining factions in the galaxy; she decided to expand their operations and overall production resulting in GMC becoming the backbone of the Commonality and thus, shifting their HQ and hubs to the Sumitra Sector.
Galacian Mining Corporation conducts logistics, prospect for raw materials, constructs and operates mines, manages vast stockpiles of raw materials and does construction of various facilities for the Commonality and it's subsidiaries.
With an enormous amount of resources and the Commonality's vast fleet of Modular Taskforce Cruisers and Bulk Freighters. GMC's ingenuity, trustworthiness, attention to detail and commitment is a prime example of how a mining company should be ran and operated.
On Year 13 Day 327, Krath Lord Frezt Raleigh was appointed leader of the Commonality to accommodate a merger between this government and the Krath Dynasty. Thus, GMC was taken over by Krath. On Year 14 Day 158, GMC was no longer needed in Krath and was offered back to The eXiles. The eXiles decided it was best to merge it with it's current mining faction EXiles Intragalactic Lithology. Minister Hugh Grishnak lead the change along with Minister Kai Niloc.

The mining machinery industry is highly dependent on mining activity in China and the world. Our mining machinery industry has been stepped into era of information and technology. When demand for mined materials is high, mine operators order new machinery; when demand is low, orders fall off. Mining machinery manufacturers are cushioned somewhat from demand cycles because different kinds of mines use similar machinery. Thus a decline in coal mining, for example, may be offset by a boom in salt mining.
‘If the government has strength in mining sector, why we can not invest in mining machinerystrongly?’
‘Because of the demand for mining machinery in China and other developing country, whose infrastructure is on the rise, so where do these suppliers go? It is right in China, coz China knows what they need now.’
In the new century and new era of China’s high speed development, China will see a massive increase in demand for the qualified and competitive powder making machinery.
After many years of practice and improvement, Raymond mill structure is getting perfect day by day. For low consumption, low investment, environment friendly , small occupation area, and more efficient than the traditional mill, it is widely used in the field of metallurgy, building materials, chemical industry and mining to process powder. The raymond mill is used in grinding the non-flammable and non-explosive stuff which has the Moh’s hardness below 7, humidity less than 6%, such as gypsum, talc, calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, bentonite, bauxite, iron ore etc., the final products change from 613 micron to 44 micron. Through the function of separator and blower, raymond mill can meet different customers’ demand.

Archaeological Screening & Reconnaissance of Acadian Mining’s Getty Development Project
Gays River, Nova Scotia
In the spring of 2008, CRM Group was retained by Acadian Mining Corporation to undertake archaeological screening and reconnaissance of the Getty Development Property, a proposed open pit mine site to access lead and zinc deposits associated with those currently being mined at the nearby Scotia Mine, located near the small rural community of Gays River, Nova Scotia.
It is anticipated that on-site surface features would include the open pit mine, a crusher, a settling pond, stockpiles of overburden and product, as well as a service road to transport ore from the Getty Development mine site to the existing milling operations at Scotia Mine.
CRM Group undertook a background study designed to explore the land use history of the study area and environs, and provide information necessary to evaluate the property’s archaeological potential. An examination of historic mapping and aerial photographs revealed that the original alignment of the Cobequid Road ran directly through the study area. Visual examination confirmed that portions of the original alignment were still visible in existing hedgerows. Several areas exhibiting high potential for encountering Precontact and/or early historic archaeological resources were also identified, as well as five potential historic sites.
As the next stage of archaeological investigation, the assessment would build upon the results generated by the initial screening. The assessment would focus on the evaluation of identified cultural features, as well as areas of high archaeological potential identified within the Getty Development study area. Shovel testing and visual assessment of cultivated fields would be used to assess the significance (age, function and integrity) of cultural features identified during the screening phase of the project.

Structural Steel Painting in Middle Tennessee
In May of 2019, the Roger’s Group Inc. hired CIP to paint the structural steel equipment at one of their rock quarries in middle Tennessee. Rogers Group Inc. is the largest privately-owned construction aggregate, crushed stone, and sand and gravel company in the United States. The company’s first of 50 quarries in Tennessee dates back to the 1940s. This first quarry was in Oak Ridge, TN, and later became the site of the Manhattan Project.
The Two Phases of the Structural Steel Painting Project
This project consisted of two phases. The first phase of the project was preparing the structural steel. We pressure washed and spot primed handrails, conveyors, a finish tower, and a scalping tower. In the second phase, we applied an industrial high-performance coating as a finish coat.
Challenges of the Project
All work in this project had to be accomplished in a period of one month while the quarry was shut down. Additionally, all our employees working on this job had to complete safety certification that met MSHA (Mine Safety and Health Administration)* requirements. So, our employees had to complete this MSHA training before we could even begin the project.
*MSHA is the government agency responsible for overseeing safety and health issues in the mining industry.
A Successful Finish

Peterson “Coal Type” vacuum disc filters are used for dewatering two products from coal preparation operations: fine “clean coal” and “refuse”. The size consist of these products is generally in the range of 28 mesh X 0. Some Peterson Filters are used on “raw coal” applications where the filter slurry contains a large portion of coal fines nearer the 28 mesh size. However, most current day clean coal filter applications are found in “flotation” circuits. In these applications, there is a very large portion of the solids in the feed slurry that are usually in the -325 mesh X 0 range.
Flocculation of the fine coal filter feed slurry is often required to obtain acceptable filtration rates together with low cake moisture. Since proper flocculent conditioning of the fine coal slurry and economical flocculent rates are essential, Peterson Filters developed a highly efficient flocculator. Our “IMAX” flocculator is used ahead of our filters to condition a variety of feed slurries and optimize the filtration step.

“Refuse” slurries are characterized by high ash content and therefore lower filter rates and higher cake moisture. In these applications proper flocculent conditioning of the filter feed slurry is absolutely essential to obtain acceptable filter operation.
The continued success of our products in fine coal applications is attributable to Peterson’s long business experience in this industry and our forward-looking approach to improving the performance of our products.

The small town of Coalwood was founded in 1905 by George Lafayette Carter, an American entrepreneur known as “the empire builder of southwest Virginia.” Carter was born on January 10, 1857, in Hillsville, Virginia. He worked at the Hillsville General Store before pursuing a career in selling iron ore properties with the Wythe Lead and Zinc Company in Austinville, Virginia. He then moved on to buying small mines throughout the area to provide coke for the Dora Furnace Company in Pulaski, Virginia. Carter would found the Tom’s Creek Coal and Coke Company and in 1898 before forming the Carter Coal Company in what would become the coal town of Coalwood.
Traveling on the back of a mule, Carter came upon rich seams of coal and bought 20,000 acres of land, constructing a mine and built offices, houses, a schoolhouse, the Carter Coal Company Store, and a church. Work soon began on the construction of the West Virginia Southwestern Railway, a 9.9-mile branch which connected with the Norfolk & Western Railroad in Gordon. The first coal mine shaft in Coalwood opened in 1914.
In 1922, Carter sold the mine and properties within the town to the Consolidation Coal Company. The company rebuilt the community and hired new employees to work the mines. When Consolidation Coal defaulted on its payments in 1933, Carter regained control of the company. After Carter died in 1936, the company was taken over by his son James who sold it in 1947 to a group of industrialists who changed the company name to the Olga Coal Company. In 1956, the Coalwood mine was connected underground to the nearby mine in Caretta, a mining community named after Etta Carter, the wife of George Carter, and also owned by the Olga Coal Company. In 1959, Olga ceased bringing coal up to the surface via Coalwood, prompting the Norfolk and Western Railway to begin pulling up the tracks leading to and from Coalwood.
The Coalwood-Caretta mine continued operations throughout most of the 20th century, producing on average one million tons annually until the mine was finally closed. At its peak, Coalwood had a population of 2,000. In 1980, the Olga Coal Company was bought by the LTV Corporation, a large US conglomerate, which closed Coalwood’s mine in 1986. The houses and businesses which were still company-owned were sold to the respective residents and business owners. In 1985, Caretta Elementary merged with Coalwood Elementary in the former Coalwood High School, but Coalwood Elementary would close the following year. Coalwood would gain fame in the late-1990s with the release of The Rocket Boys, a memoir written by former NASA engineer Homer “Sonny” Hickam Jr. about his boyhood pursuit of amateur rocketry in the coal-mining town of Coalwood.
