Mining is the extraction of valuable minerals or other geological materials from the earth, from an orebody, lode, vein, (coal) seam or reef, which forms the mineralized horizon and package of economic interest to the miner.
To gain access to the mineralised package within the lease area (aka Mining Rights Lease) it is often necessary to mine through (to create access, shafts, addits, ramps) or remove to the side waste material which is not of immediate interest to the miner. The total movement of ore and waste, which also includes the removal of soil in some cases, is referred to as the mining process. Depending on the nature, attitude, and grade of the orebody, it is often the case that more waste than ore is mined during the course of the life of a mine. The waste removal and placement is a major cost to the mining operator and to facilitate detailed planning the detailed geological and mineralisation characterization of the waste material forms an essential part of the geological exploration programme.
London Mining is an expanding producer of high specification iron ore for the global steel industry and is focused on identifying, developing and operating sustainable mines. London Mining commenced sales from the Marampa mine in Sierra Leone in 2012 and expects to reach production capacity of 5Mtpa in 2013. A prefeasibility study was completed in 2011 which shows that Marampa has resources to support a staged expansion to over 16Mtpa. London Mining has also completed bankable feasibility studies outlining plans for a further 20Mtpa of iron ore production by developing two other mines in Greenland and Saudi Arabia. In addition London Mining is producing from a coke operation with coking coal resource potential in Colombia. The Company listed on London AIM on 6 November 2009.
