Pebble Mine (Copper/Gold Prospect)The proposed Pebble Mine is located in Southwest Alaska, on state land near Lake Iliamna and Lake Clark, and is situated atop the largest known gold deposit in the world. If built, the mine would be North America's largest gold and copper mine, potentially producing hundreds of billions of dollars worth of metals. The proposed mine is also located at the headwaters of some of the world's most productive salmon rivers, which ultimately feed into fisheriesrich Bristol Bay. The potential enviro

The current market value of the Pebble deposit is greater than $300 billion, using 2013 estimates of recoverable metals and July 14, 2014 metal spot prices. This breaks down to roughly $179 billion in copper, $43 billion in molybdenum, and $87 billion in gold. This is down from $500 billion several years ago, due to downward revisions of the Northern Dynasty's 2010 estimated recoverable metal, and a drop in gold prices.

    Pebble Project, Alaska Mining Technology Mining News and A draft watershed assessment of the Bay Area released in May 2012 by the US Environmental Protection Agency raised significant environmental concerns, which has led to concerns over the Pebble Partnership. An independent consultation process led by Keystone Center was started in October 2012 to discuss the Pebble Environmental Baseline Document (EBD) at length and to receive public input. The proposed Pebble mine has the potential to produce about one third of the United States annual copper needs for many years. However, uncertainty hovers around the project as the US Environmental Protection Agency (EPA) has advised that the project be scrapped, citing its predicted environmental impact. Pebble has also witnessed significant opposition from local native groups and fishing organisations. The main controversy over the mines development is that the project will endanger salmon and other fisheries in the Bristol Bay region.

    The western section of Pebble deposit was explored between 1988 and 1997 by Cominco (now Teck), which initially held the mineral rights at Pebble. Northern Dynasty acquired the Pebble deposit between 2001 and 2005. The known mineral resource at Pebble was extended from one billion tonnes in 2001 to four billion tonnes by 2004. Higher grade mineralisation was discovered at Pebble East area in 2005. Preliminary engineering, environmental and technical studies for developing the Pebble Project had already begun by this time. In July 2007, Northern Dynasty entered into a 50:50 partnership programme with Anglo American to develop the Pebble deposit. As per the agreement, Anglo American was required to fund $1.5bn for the project for securing its interest and the expenditures were to be split 50:50 later. Anglo American funded $41m in the Pebble Project until it withdrew from the partnership in 2013. The project is now 100% owned by Northern Dynasty. Wardrop completed preliminary technica

    Pebble is a coppergoldmolybdenum porphyry deposit with the ore body extending up to 1,700m deep from the surface. The deposit is located in the sedimentary basin called Kahiltna Terrane and is believed to have formed about 90 million years ago. Pebble is one of the largest copper discoveries in the world although the ore body contains less than 1% copper by volume. Metallic minerals found at Pebble include pyrite, chalcopyrite, molybdenite and bornite along with certain amounts of covellite, chalcocite, digenite and magnetite. The minerals of Pebble deposit are found in fine grains sprinkled throughout the rock. Mineralisation at the western section of Pebble is partially exposed at the surface, whereas the Pebble East hosts higher grade mineralisation deeper beneath the surface.

    The transportation plan for Pebble project involves the construction of a port on Iniskin Bay of Cook Inlet from where the mineral concentrates can be shipped to the smelter. The port is planned to be connected with the mine site through two freight corridors 86 miles in length along the north side of Lake Iliamna. Four pipelines for carrying coppergold concentrate, reclaim water, natural gas and diesel fuel along the road are also being considered to be built. The slurry will be dewatered at the port and the reclaimed water will be sent back to the mine. A 400MW natural gas fired power plant is planned to be built at the mine site.
