Predicting mine waste environmental impacts before it’s too late
Mining for precious, base and ferrous metals can result in millions of tonnes of tailings and waste rock, which if left unmanaged can have dire environmental consequences. Laura’s research is finding methods to predict how a mine’s waste might impact the environment before it’s even created.
Blowing Up Mountains: Destroying the Environment for Coal
Massive corporations are blowing up mountains and creating environmental ruins in West Virginia. All this devastation, just to extract some coal. We went to West Virginia to investigate mountain-top removal -- which a way of extracting coal from deposits under mountains. Instead of drilling into the mountain and sending men underground to take out the coal in the traditional way, they just take the whole top of a mountain off.

THANATIA -- The Destiny of the Earth's mineral resources
Is Gaia becoming Thanatia, a resource exhausted planet? For how long can our high-tech society be sustained in the light of declining mineral ore grades, heavy dependence on un-recycled critical metals and accelerated material dispersion? These are all root causes of future disruptions that need to be addressed today. This book presents a cradle-to-cradle view of the Earth's abiotic resources through a novel and rigorous approach based on the Second Law of Thermodynamics: heat dissipates and materials deteriorate and disperse. Quality is irreversibly lost. This allows for the assessment of such depletion and can be used to estimate the year where production of the main mineral commodities could reach its zenith. By postulating Thanatia, one acquires a sense of destiny and a concern for a unified global management of the planet's abiotic resource endowment. The book covers the core aspects of geology, geochemistry, mining, metallurgy, economics, the environment, thermodynamics and thermochemistry. It is supported by comprehensive databases related to mineral resources, including detailed compositions of the Earth's layers, thermochemical properties of over 300 substances, historical energy and mineral resource inventories, energy consumption and environmental impacts in the mining and metallurgical sector and world recycling rates of commodities.

Mining Matters in your Everyday Life
This video by the Colorado Mining Association presents an informative and educational video on how mining matters to each and every one of us in our every day life, not just in Colorado but around the world. Many do not realize that our modern society relies on mining for many of the products and comforts we enjoy including such electronic devices such as computers, cell phones, MP3 Players, home appliances, and medical diagnostic equipment to name a few . Many of the facets of the lifestyle we enjoy in Colorado would not be possible without mining, including ski lifts, roadway anti-skid treatments, mountain bikes, , as well as the heat , shelter and electricity needed to survive a long cold mountain night. Colorado is a major producer of molybdenum (called moly for short) which is used in stainless steel, cars, lubricants, and light bulbs. Moly is also used in automotive catalytic converters, to help keep our environment clean. Mining provides for personal health care products you use every day such as cosmetics, toothpaste, deodorant, calamine lotion, baking soda, and your sunscreen! 72% of Colorado's electricty is provided by clean, abundant coal. Coal provides 50% of the electricity nationwide. Colorado coal is low in ash and sulfur; therefore, it is considered "clean coal" Modern methods of filtering and scrubbing coal plant stack emissions provide for cheap and affordable energy to energize our economy and meet the affordable energy costs with little emissions into our environment. Alternative energy such as wind, solar , hydro and geothermal options become a feasible component for fulfilling our Nations' energy needs. Colorado is pursuing an aggressive alternative energy program which depends on the mining industry to provide the raw materials to build the solar panels, wind turbines, hybrid cars, and transmission line infrastructure required to meet the demands of these future programs. Bio-Fuel production, and modern agriculture in general would not be possible without the fertilizer and pest control products which rely on mining for some ingredients. Many do not realize that Colorado uranium is used around the world to fuel clean, efficient, zero emissions nuclear energy facilities in both the industrial and military sectors. Modern mining is conducted without damaging the environment. Any surface disturbances are restored back to their natural condition, typically providing an improved animal habitat. Modern Mmning is environmentally sound and actually safer than most other occupations. You are far more likely to be injured working in the retail, construction or transportation industries than working in a mine, above or below ground. Colorado miners are typically persons who love and actively protect their fragile mountain environment in which they live and work. They usually live in close proximity to the mines and go above and beyond any environmental or safety regulations, not only in their stewardship of environmental protection, but for the protection of their families, homes, co-workers and community in which they live.

Mining, Ecological Engineering and Metals Extraction for the 21st Century
Speaker: Margarete Kalin, Research Director and President of Boojum Research Ltd. This webinar is an introduction to a recent contribution on sustainable mining, remediation and metal extraction to the Oxford Research Encyclopedia of Environmental Science, Problems and Solutions. Co- authors are M. Kalin, Michael P. Sudbury and Dr. Bryn Harris. The mining industry developed in an age when resources, space and water appeared limitless. A paradigm shift is needed in mining, remediation and extractive metal processes. Human’s insatiable appetite for metals is estimated to produce annually 20 billion tons of waste rock and tailings, covering about 1000 km2 of land. The annual consumption of fresh water is estimated to be about 80 10-9 tons, most of it will be contaminated. A collision course is on the horizon, given shortages of water and arable land and the ever-increasing global population. The key to a solution to the present un-sustainable environmental management practices lays in ecologist’s view of mining wastes as extreme primordial environments. Natural recovery processes can be supported through ecological engineering measures. This starts with exploration and through to operations, ending with decommissioning. By providing physical and chemical support to promote existing ecological processes within the wastes, we can alter the surface of minerals, thereby decreasing contaminant generation and reducing the volume of drainage by promoting run-off. Supporting the growth of indigenous biota leading to increased agglomeration of contaminant on the cell surfaces and upon death the biomass with its contaminants sinks to the sediments. Through bio-mineralization in the sediment, the metals are stabilized, potentially generating in the long-term biogenic ore bodies. All processes are implemented within the mine waste and water management area. Brief examples are given of: -Acid Reduction Using Microbiology through sediment construction; -Alterations of the mineral surface on waste rock reducing sulphide oxidation by effective nutrient supply carried into the wastes by rain and; -Biological polishing “in alkaline and acid mine waste water by a pH adjustment (if needed) and adjusting nutrient imbalances; -Estimates of reductions in waste generation using efficient metals extraction processes. Boojum’s multidisciplinary team of scientists guided by experts of the industry, has laid the foundation for ecological engineering in publications and field demonstration projects. Moving forward we need to evaluate these demonstration project to use the results to build confidence in the approach of ecological engineering, only then can we achieve the paradigm shift needed for the future of the industry. Learn about the speaker: Margarete Kalin is Research Director and President of Boojum Research Ltd. The R& D firm in collaboration with mining companies, the Canadian government and research organizations , has developed and demonstrated an ecological toolkit, that leads to a self-sustaining decommissioned mine waste and water management area. More than 100 scientific publications, numerus chapters in technical books documenting the natural processes and approximately 150 project reports are available on line at http://biblio.laurentian.ca/boojum. Margarete received the Noranda Award for Outstanding Achievements in Land Reclamation from the Canadian Land Reclamation Association and the Teck-Cominco Environmental Award from the Canadian Institute for Mining and Metallurgy (CIM). She was nominated in 2005 as a Distinguished Lecturer by the CIM. She is certified as a QEP (Qualified Environmental Professional ) by the Institute of Professional Environmental Practice and as a Senior Ecologist by the Ecological Society of America. She has been Adjunct Professor at several Canadian universities.

Mine Cristal, mining quartz crystals
www.minecristal.ca Stay informed about our new videos: subscribe to our YouTube channel "Mine Cristal". This mine is located in Bonsecours, Quebec, Canada. Photos and video clips shown here date from 1989 - 2012. The open-pit mine produces splendid quartz crystals with exceptional clarity. The largest single crystals measure 60 cm (24 inches) in length. Since mining began in 1989, 32 types, or morphologies of quartz crystals have been catalogued. Geological research into the origins of these crystals has revealed that they formed at this location some 300 million years ago under extreme conditions of heat and pressure. We harvest crystals in the mine only as needed, to supply our store with a sufficient quantity of quartz crystals. Exceptionally (for a mine), we harvest all the crystals by hand and without the use of dynamite. It is a privilege for us to participate in the discovery and extraction of these true gems of nature. The extraction process is done in a manner which respects both the environment and the crystals: we endeavor to keep the crystals whole and in a pristine state. In the museum and the store, our crystals are presented in an untouched, natural state. Amazingly, each crystal is an intricate work of art made by Nature; no two are alike and this makes them even more fascinating! Mine Cristal is considered by experts to be a “geological gem,” one of Canada’s great natural sites, due to it’s unique and abundant mineralogical deposits.

Uranium Mining in US and Canada in the 1970s
Physically removing the rock ore generally involves either open-pit mining or underground mining. Milling is the process that removes uranium from the ore, which is mostly obtained in open-pit and underground mines. Once at the mill, the ore is crushed and ground up, and treated with chemical solutions to dissolve the uranium, which is then recovered from the solution. Tailings are the wastes from the millings processes and are stored in mill tailings impoundments, a specially designed waste disposal facility. Since 1979, when uranium mine workers began being diagnosed with lung diseases, such as cancer, regulators have gradually tightened controls and mandated improved uranium mining practices. Recently, officials also have become concerned with the broader impacts of uranium mining on public health and the environment. Workers are directly exposed to the radiation hazards of uranium mines. Uranium mining also releases radon from the ground into the atmosphere. Mines and mining waste can release radionuclides, including radon, and other pollutants to streams, springs, and other bodies of water. Federal and state agencies have established pollutant discharge limits and drinking water standards, and continue to monitor these sites for public safety. Uranium mine waste from operations that closed before the mid-1970s are of particular concern. In many cases, these mines remain unclaimed and the waste is still piled near the mine. Weathering can lead to radioactive dust that is blown by the wind and the seepage of contaminants into the surface and groundwater. There are also cases of unclaimed uranium mine waste being used for house construction, which creates significant radon and radiation hazard for inhabitants. For more information on the hazards of uranium, go to USEPA website http://www.epa.gov/radtown/basic.html . This is clipped from the late 1970's BBC Production, Energy From The Crust, showing uranium mining activities and equipment and including footage from the following uranium mines: Schwartzwalder Mine, Near Boulder, Colorado King Solomon Mine near Uravan, Colorado and the Key Lake Mine in Saskatchewan, Canada.

50 Mining Engineering Interview Questions And Answers || Frequently asked questions in an interview
Mining engineering is an engineering discipline that applies science and technology to the extraction of minerals from the earth. Mining engineering is associated with many other disciplines, such as geology, mineral processing and metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations – from exploration and discovery of the mineral resource, through feasibility study, mine design, development of plans, production and operations to mine closure. With the process of Mineral extraction, some amount of waste and uneconomic material are generated which are the primary source of pollution in the vicinity of mines. Mining activities by their nature cause a disturbance of the natural environment in and around which the minerals are located. Mining engineers must therefore be concerned not only with the production and processing of mineral commodities, but also with the mitigation of damage to the environment both during and after mining as a result of the change in the mining area. Salary and statistics Mining salaries are usually determined by the level of skill required, where the position is, and what kind of organization the engineer is working for.[citation needed] When comparing salaries from one region to another, cost of living and other factors need to be taken into consideration. Mining engineers in India earn relatively high salaries in comparison to many other professions, with an average salary of $15,250. However, in comparison to mining engineer salaries in other regions, such as Canada, the United States, Australia and the United Kingdom, Indian salaries are low. In the United States, there are an estimated 6,630 employed mining engineers, with a mean yearly salary of USD$90,070. Education Students outside Colorado School of Mines campus There are many ways to become a Mining Engineer but all include a university degree in Mining Engineering. Primarily, training includes a Bachelor of Engineering (B.Eng. or B.E.), Bachelor of Science (B.Sc. or B.S.), Bachelor of Technology (B.Tech.) orBachelor of Applied Science (B.A.Sc.) in Mining Engineering. Depending on the country and jurisdiction, to be licensed as a mining engineer a Master's degree; Master of Engineering (M.Eng.),Master of Science (M.Sc or M.S.) or Master of Applied Science(M.A.Sc.) maybe required. There are also mining engineers who have come from other disciplines e.g. from engineering fields likeMechanical Engineering, Civil Engineering, Electrical Engineering,Geomatics Engineering, Environmental Engineering or from science fields like Geology, Geophysics, Physics, Geomatics, Earth Science,Mathematics, However, this path requires taking a graduate degree such as M.Eng, M.S., M.Sc. or M.A.Sc. in Mining Engineering after graduating from a different quantitative undergraduate program in order to be qualified as a mining engineer. The fundamental subjects of mining engineering study usually include: Mathematics; Calculus, Algebra, Differential Equations,Numerical Analysis Geoscience; Geochemistry, Geophysics, Mineralogy, Geomatics Mechanics; Rock mechanics, Soil Mechanics, Geomechanics Thermodynamics; Heat Transfer, Work (thermodynamics), Mass Transfer Hydrogeology Fluid Mechanics; Fluid statics, Fluid Dynamics Geostatistics; Spatial Analysis, Statistics Control Engineering; Control Theory, Instrumentation Surface Mining; Open-pit mining Underground mining (soft rock) Underground mining (hard rock) Computing; MATLAB, Maptek (Vulcan) Drilling and blasting Solid Mechanics; Fracture Mechanics In the United States, the University of Arizona offers a B.S. in Mining Engineering with tracks in mine operations, geomechanics, sustainable resource development and mineral processing. South Dakota School of Mines and Technology offers a B.S. in Mining Engineering and also an M.S. in Mining Engineering and Management and Colorado School of Mines offers a M.S. in Mining and Earth-Systems Engineering, also Doctorate (Ph.D.) degrees in Mining and Earth-Systems Engineering and Underground Construction and Tunnel Engineering respectively. In Canada, McGill University offers both undergraduate (B.Sc. or B.Eng.) and graduate (M.Sc. or M.S.) degrees in Mining Engineering. and the University of British Columbia in Vancouveroffers a Bachelor of Applied Science (B.A.Sc.) in Mining Engineering and also graduate degrees (M.A.Sc. or M.Eng and Ph.D.) in Mining Engineering. In Europe most programs are integrated (B.S. plus M.S. into one) after the Bologna Process and take 5 years to complete. InPortugal, the University of Porto offers a M.Eng. in Mining and Geo-Environmental Engineering and in Spain the Technical University of Madrid offers degrees in Mining Engineering with tracks in Mining Technology, Mining Operations, Fuels and Explosives, Metallurgy.

Business and Leisure | BIZWATCH:  DENR Wants To Limit Mining Areas
The Department of Environment and Natural Resources is officially limiting the areas to be mined and developed as part of the president’s directives to regulate mining operations towards sustainable development. Environment Secretary Roy Cimatu recently signed DENR Administrative Order 2018-19 which provides new environmental policies that will ensure sustainable environmental conditions at every stage of mining operations, and minimize the disturbed area of a mining project at any given time. The order covers all mineral agreements, financial or technical assistance agreements, and other similar mining tenements that have surface metallic mines under development, construction or are already operating. Meanwhile, mine sites with processing plants or those with long-term supply agreement with domestic processing plant can develop up to 162 hectares or two meridional blocks. However, areas utilized for ancillary facilities, such as settling ponds, stock yards, sumps, motor pools, administrative offices, and other similar facilities, are not included in the maximum disturbed area limit. Temporary revegetation or progressive rehabilitation shall also be implemented immediately on the disturbed areas exceeding the maximum disturbed area limit. Apart from limiting the areas, additional environmental include topsoil and subsoil management, buffer zone management, and pier stockyard as temporary stockpile area for ore shipment. The order also states that during the course of operation, an equivalent area should undergo temporary revegetation or progressive rehabilitation should the contractor or holder of other mining tenements intend to open an additional area beyond the maximum disturbed. This is to ensure that the maximum disturbed area limit is strictly observed. The Chamber of Mines of the Philippines, meanwhile, supports the recent order, particularly in ensuring sustainable environmental conditions at every stage of the mining operation and minimizing the disturbed area of a mining project at any given time. The DENR warned that non-implementation of temporary revegetation provisions under the order may lead to fines, non-issuance of transport permits, or total cancellation of mining agreements.

Secretary Salazar's remarks on June 20, 2011 from the Grand Canyon
PROPOSED MINERAL WITHDRAWAL NEAR GRAND CANYON NATIONAL PARK What was announced on June 20, 2011? Secretary of the Interior Ken Salazar announced his decision to make an emergency withdrawal for six months of approximately 1 million acres of federal lands near Grand Canyon National Park from hard rock mining claim location and entry under the 1872 Mining Law while the Department continues to evaluate whether to withdraw these lands from new mining claims for 20 years. Valid existing claims are not affected by this announcement. What are the next steps? A Public Land Order making an emergency withdrawal of six months will be published in the Federal Register within the next week. A final EIS is expected to be released to the public in the fall of 2011. Why is this action of an emergency withdrawal necessary? On July 21, 2009, the Department published a notice in the Federal Register of a proposed withdrawal of approximately 1 million acres of federal locatable minerals on both BLM and Forest Service lands in northern Arizona from location and entry under the 1872 Mining Law and that action began a two-year temporary segregation period that expires on July 20, 2011. This action is necessary to prevent the lands from opening to new mining claim location and entry under the 1872 Mining Law when that segregation expires. What is the preferred alternative? The preferred alternative that will be included in the final Environmental Impact Statement (EIS) is the full proposed withdrawal of approximately 1 million acres of BLM and Forest Service lands located near Grand Canyon National Park from mining claim location and entry under the 1872 Mining Law for 20 years, subject to valid exiting rights. The selection of a preferred alternative is required as part of the development of an EIS under the National Environmental Policy Act. The EIS to analyze a proposed withdrawal of these lands of up to 20 years is currently under development and is expected to be completed in the fall of 2011. Has there been public input? Over 295,000 public comments were received during the public comment period on the EIS, which included an initial period of 45 days and was extended 30 days to allow for additional public comment. The interagency team worked with eleven other cooperators and held thirty-one consultation meetings with tribes. Who are the cooperating agencies? U.S. Forest Service; National Park Service; U.S. Fish and Wildlife Service; U.S. Geological Survey; Arizona Game and Fish Department; Arizona Geological Survey; Arizona Department of Mines and Mineral Resources; Arizona State Land Department; Hualapai Tribe; Kaibab Band of Paiute Indians; Coconino County, Arizona; Mohave County, Arizona; Kane County, Utah; San Juan County, Utah; and Washington County, Utah. What lands are affected by today's announcement? These lands are within portions of the Grand Canyon watershed next to Grand Canyon National Park and contain significant environmental and cultural resources as well as known uranium deposits. The Grand Canyon National Park is an iconic American landscape and World Heritage Site and draws 4.4 million visitors each year, is home to numerous rare, endemic and specially protected plant and animal species and contains vast archeological resources and sites of spiritual and cultural importance to American Indians. The Colorado River and its tributaries that flow through the watersheds of Grand Canyon National Park supply water to agricultural, industrial, and municipal users, including the cities of Tucson, Phoenix, Las Vegas, Los Angeles, and San Diego. What is an emergency withdrawal? During an emergency withdrawal, like a temporary segregation, the location of new hard rock mining claims under the 1872 Mining Law would be prohibited, however ongoing or future mining exploration or extraction operations on valid pre-existing claims could continue. The temporary segregation expires on July 20, 2011. Does this announcement affect oil, gas, coal, or other non-hard rock energy resources in the proposed withdrawal area? No. How many mining claims are there? At the time of the proposed withdrawal and temporary segregation, 10,600 hard rock mining claims existed. Today, approximately 3,500 claims remain. The emergency withdrawal will help maintain the status quo until a final decision is made on the proposed withdrawal. Where can I go to find out more information?

The declining price of copper: impact on Arizona mining with Nyal Niemuth
Arizona Mining Review: 1/28/15, episode 25, part 2
Presentations by Abbey, Jarvis, & McNutt on June 20, 2011 at the Grand Canyon
PROPOSED MINERAL WITHDRAWAL NEAR GRAND CANYON NATIONAL PARK On June 20, 2011, Secretary of the Interior Ken Salazar was joined at the Mather Point Amphitheater in Grand Canyon National Park by BLM Director Bob Abbey, National Park Service Director Jon Jarvis, and US Geological Survey Director Marcia McNutt. In this video, the three directors, in turn, address the audience, then, Secretary Salazar answers questions posed by the media. In remarks regarding the potential withdrawal of certain federal lands near the Grand Canyon from new mining claims, Secretary of the Interior Ken Salazar said that management of the Grand Canyon area must be guided by "caution, wisdom, and science," so as to protect the World Heritage Site, tribal interests, drinking water supplies, and the tourism economy that the area's natural resources support. In his remarks, Secretary Salazar stated that he will take action to prevent the opening of one million acres of public and National Forest System lands surrounding the Grand Canyon to new uranium mining claims while the Bureau of Land Management (BLM) completes a final Environmental Impact Statement that evaluates a preferred alternative of a 20 year mineral withdrawal on those same lands.

Protection Against Radioactivity in Uranium Mines 1969 US Bureau of Mines
This film from the United States Bureau of Mines presents general descriptions of the hazards of radon daughters in uranium mines, and outlines the environmental control, principles and procedures for mitigating the hazard. Scenes of underground mines show the origin and reason of the hazard, and various methods of ventilation are shown on how to correct the condition. Uranium mining occurred mostly in the southwestern United States and drew many Native Americans and others into work in the mines and mills. Despite a long and well-developed understanding, based on the European experience earlier in the century, that uranium mining led to high rates of lung cancer, few protections were provided by employers or government for US miners before 1962 and their adoption after that time was slow and incomplete. Some US officials and scientists advocated ventilation requirements in US mines as a proactive, preventative measure during the 1950s, on the basis of their knowledge of European experience. Duncan Holaday, an industrial hygienist with the PHS, has generally been recognized as the most prominent advocate for ventilation. He led the effort to obtain measurements of radon in the mines, and he used the data to argue forcefully within the government that ventilation would be effective and was feasible. His arguments achieved only limited success, as there was government resistance to requiring ventilation and his views were not made public at the time. The Atomic Energy Commission (AEC) was an obstacle. In the late 1940s, controversy erupted in the New York Operations Office over the hazards from beryllium and uranium mining. The AEC wrote worker health requirements in contracts with companies that handled beryllium. After conflicting recommendations from staff, it chose not to establish such requirements for uranium. It claimed to lack legal authority, but it did not explain the legal difference between uranium and beryllium. The AEC did not lack knowledge: records of a January 25, 1951, internal meeting of AEC and PHS staff reveal that, on the basis of early measurements, they believed that radon was present in levels that would cause cancer and that ventilation could abate the hazard. Public acknowledgment of this problem was apparently squelched. For instance, Hueper, the scientist who wrote the 1942 review and who was then at the National Cancer Institute, was forbidden to speak in public about his concerns about the health hazard of radon in uranium mines. It is reported that he was even forbidden to travel west of the Mississippi, lest he say too much to the wrong people. The resulting high rates of illness among miners led in 1990 to passage of the Radiation Exposure Compensation Act. For more details, see the outstanding article, The History of Uranium Mining and the Navajo People, in the Sept 2002 American Journal of Public Health at http://www.ajph.org/cgi/reprint/92/9/1410 .

Residents block railways to stop copper mine operating after chemical spill
The copper mine responsible for a chemical spill in Mexico's northern state of Sonora may have to pay millions of dollars to rectify damage done to the local environment and injury caused to residents, authorities said on Tuesday. Protesters blocked roads leading to the mine on Tuesday as Mexican Environment Secretary Juan Jose Guerra Abud told reporters in Mexico City that investigations were ongoing to determine the exact figure the owners of the mine, Grupo Mexico, would have to pay. The spill at the Buenavista del Cobre copper mine, just south of the border with the United States, sent about 10 (m) million gallons (40-thousand cubic metres) of mining acids into two rivers and on to a dam that supplies water to Hermosillo, the capital of Sonora state. Environmental authorities have said that 24-thousand people have been affected by the spill, and five people had to be hospitalised. Carlos Esquer, a miner protesting outside the mine on Tuesday, said that they wanted to force the company into dealing with the problem. "Our pressure here is strong, we are using every available obstacle to stop the mine working and take care of the serious problems it has today," he said. The mining company had claimed that the spill on 7 August was caused by unusually heavy rainfall, but officials say a construction defect at a holding pond allowed mining waste to flow out.

Royal NIOZ & STW - Ecology research on Deep Sea Mining - Azores
Can valuable mineral resources on the ocean floor be responsibly mined? To answer this question, we need to know much more about the deep-sea environments where these minerals occur in high concentrations. In April 2015, an international team of marine scientists sailed with the Dutch research vessel 'Pelagia' of Royal NIOZ to a site southwest of the Azores. Their mission: to collect data and perform experiments around a deep-sea hydrothermal vent field located on the Mid Atlantic Ridge. Sulfide minerals precipitating from the hydrothermal exhausts locally form massive sulfide deposits at the seafloor. In places where hydrothermal activity has ceased, these mineral deposits may become economically viable mining sites. Scientific understanding of the key geological, oceanographic and biological processes at those sites is of pivotal importance for policy makers to weigh the potential gain of valuable minerals against the potential environmental risks of deep sea mining.

The Mine of the Future—Clareo's Peter Bryant at SME Conference
Peter Bryant, partner at Clareo and Senior Fellow, the Kellogg Innovation Network (KIN), discusses the mining company of the future at the Society for Mining, Metallurgy and Exploration's conference. The Society for Mining, Metallurgy & Exploration (SME) in partnership with the Colorado Mining Association (CMA) hosted a pivotal keynote session during their joint meeting, February 16, 2015. The session was titled, "The Mine of the Future: Forecasting Opportunities and Challenges for the Global Mining Industry," and examined how the international mining industry is softening as the global economy expands at a more moderate pace and mine capacity may have outstripped demand in the short term. However, in the individual mining sectors of coal, metal, industrial minerals and aggregates, opportunities await for smarter companies that are meeting their own domestic and international challenges by opening new markets, creating new products, cutting costs and improving efficiencies. This multi-industry sector panel addressed both the opportunities and challenges that lie ahead for each mining sector.

Global Climate Change Policy - Extractive Industry Impacts and Response
Jeff Hopkins, Principal Adviser for International Energy and Climate Policy at Rio Tinto, presented on October 29, 2013 as part of the AEDE Applied Economics Seminar Series. His presentation focused on climate change policy as experienced by an international mining company. This seminar was sponsored by Ohio State's Environmental Policy Initiative. Dr. Hopkins leads policy engagement in the U.S. and Canada for Rio Tinto and works with a globally-distributed corporate team as well as external affairs and environmental specialists who work on-site at Rio Tinto mines and businesses. Rio Tinto is the largest diversified mining company in the U.S. and the second-largest mining company in the world, with major operations producing iron ore, copper, aluminum, uranium, thermal and metallurgical coal, gold, and industrial minerals. As part of their mining, refining, and smelting of these metals and minerals, Rio Tinto emits 41 million tons of GHG emissions per year. Over 70 percent of these GHG emissions occur in places where carbon is regulated through a price-based scheme such as cap and trade or a carbon tax. Dr. Hopkins' policy education and advocacy work on behalf of Rio Tinto at the national and regional levels, often in collaboration with the larger business community and environmental NGOs, is based on extensive experience in scheme development and implementation. Prior to working for Rio Tinto, Dr. Hopkins was a policy analyst and chief economist for the United States House of Representatives Committee on the Budget, and before that for USDA's Economic Research Service. Dr. Hopkins received a PhD from AEDE in 1998, and was a Peace Corps Volunteer in Guatemala from 1987-1989.

Ellis Martin Report with Ross Orr of BacTech Environmental
In this broadcast of The Ellis Martin Report, Ellis reports from Toronto where he attended PDAC, the Prospectors and Developers Association of Canada, the largest mining conference in the world. Join him for a conversation with Ross Orr, the President and CEO of BacTech Environmental Corporation, trading on the CNSX under the symbol BAC. BacTech is a pioneering, environmental technology company that has developed and commercialized a proprietary technology to remediate highly toxic tailing areas resulting from abandoned mining operations. BacTech's core technology, called "bioleaching", employs naturally-occurring bacteria, harmless to both humans and the environment, to oxidize the sulphide materials left behind after years of mining. The tailings may contain ores and related materials contaminated by arsenic and other substances that are poisonous to humans and animals, as well as harmful to the local environment. The sulphides in the tailings react (oxidize) with the atmosphere to create an acidic solution called acid mine drainage (AMD), which leaches into the surrounding area over time. BacTech's bioleaching process can stabilize these toxins from minerals and prevent additional harmful AMD. The technology provides a "Garden of Eden" environment for the bacteria to thrive and multiply and permits them to achieve in 6 days what would normally take 20 years to occur naturally. http://www.ellismartinreport.com http://www.bactechgreen.com contact: martinreports.com

Two Guatemalans picked up for illegal gold panning
For the latest news across Belize, visit: http://edition.channel5belize.com/ Two Guatemalan men are serving eight months in jail for illegally entering Belize, specifically the Chiquibul National Park, to mine for gold. The joint work of Police, Belize Defence Force and Friends for Conservation and Development personnel a week ago on November twenty-fifth led to the capture of Anibal Qui-ix Cucul of Monte Los Olivos, Petén, and Jose Amilcar Garcia Morales of Huite, Zacapa, Guatemala, who were convicted in Belmopan Magistrate’s Court on Wednesday. It is uncertain if the Mining Unit will further charge them for extracting minerals without a permit. F.C.D. is once again warning of environmental impacts in the area as a result of the gold panners’ actions, although despite the presence of a conservation post in the area, the constant moving around makes it difficult to track offenders. News Five spoke to its executive director, Rafael Manzanero, today.

THIS VIDEO IS BROUGHT TO YOU BY GEMSTONESOFBRAZIL.COM, Lavra Pedra Grande in a Gemstone mine located in the Brazilian state of Minas Gerais, near the small beautiful town of Itaiomi. My mining crew and I arrived and started cleaning this mine at the end of 2013, which was the first major cleanup in the mine since the mine totally caved in 2002. Even though the mine has been a gem mine for over 50 years, and is recognized by the Brazilian government to have the mineral compositions to extract Aquamarine and Tourmaline gemstones which is documented in the mines Brazilian governments mineral rights agreements. Cleanup took 6 months of very very intensive cleaning using a Caterpillar 320D. After the cleanup was completed, my mining crew and I got very busy looking gemstones in the mine. Over the fallowing 6 months we found evidence of green tourmaline and found a lot of Aquamarine gemstones.In the beggining we discovered a crack on top of the mountain above the mine and was told by many sources that this crack was there before 2002. The crack ran along the highest top ledge of mountain above the mine, and at first the crack was very thin and everyone dispelled it as something not to worry about, but we agreed to keep our eyes on the crack. With time, rain, and with hundreds of mining demolition blasting below the mountain the crack was slowly getting larger. The first video above was shot 2 days before the second video was shot showing the mine caving down into the mining areas. It was the day of the first video I decided to pull my mining crew and equipment out of the mine and stop all work because the crack was getting larger, and I could not risk anyone`s life. At this point I felt it was time to close the mine because it was to dangerous to work below the mountain. As a last resort to continue mining for gems my mining crew and I agreed to set explosive charges on another crack on a smaller hill outside the danger zone below the mountain. Two days after I removed everyone from below the mountain`s danger zone we set the explosive charges on top of the small hill. We used 1 liter soda bottles filled with granulated explosives to cause 3 times the normal blast with each soda bottle hoping the explosion would open the cracks on the small hill to cause the hill`s stone ledge to fall down so we could continue mining by making this area safe. We set the explosive charges on the hill and everyone took their safe positions waiting for the explosives to explode.The explosion toke place but was not loud and somewhat drown out by the dirt that was use to cover the soda bottles inside the hills crack hoping to cause more impact in the explosion. We all came out of our safe places to view the result of the blast. After examining the blast site we realized that the blast did not do anything at all to effect in any way the small hills crack, and we all knew this plan will ever be successful in the future. We walked down from the small hill to the truck near the water containers and I was thinking or mining is over until God decides to do his will and cause the mountain`s ledge to fall down and eliminate the dangers caused by the crack on the mountain, which could very possibly be 10 years or more, only God would know. When we arrived at the truck we started to hear a crackling noise coming from the mountain.To our great surprise we started to see sand and stones falling from the mountain. Well the rest of the story is in the video, please watch. After the mountain`s cave in, I decided it was God`s will to take the mountain down in which I felt he was telling me not to give up. The very next day we started cleaning the mine for a second time with 2 tractors which took one and a half months to complete the cleanup and continued to find Aquamarine.

OPG DGR Hearing -- Presentation by Dr. John Adams, Seismologist, Natural Resources Canada
This video is part of a selection of presentations made at the joint review panel public hearings for the proposed Ontario Power Generation's (OPG) Deep Geologic Repository (DGR) project. The DGR project proposes a solution to the long-term management of low- and intermediate- level radioactive waste, by placing it in a storage space excavated in half-a-billion year-old sedimentary rock. The three-member panel conducted the hearing to assess OPG's environmental impact statement and application for a licence to prepare a site and construct the proposed DGR. The hearings ran from September 16 to October 12, and then from October 28 to 30 in Bruce County (Kincardine and Port Elgin), Ontario.
