Sociedade De Desenvolvimento Mineiro
Sociedade de Desenvolvimento Mineiro (SDM) is an Angolan public mining company and holds the mining rights in an area of concession of 2,950 km2, located in the hydrological basin of Cuango River, Lunda Norte Province. As joint venture, its board of shareholders includes the following companies: Endiama (National Diamond Company of Angola), an Angolan public company and OMSI (Odebrecht Mining Services Inc), a Brazilian private company. It prospects, develops, mines and trades diamonds from primary and secondary deposits, identified in the region of Cuango River, in the north-eastern region of Angola that produces good quality stones. Bulk sampling of river terrace gravels in the vicinity of the Ganzo, Tázua and Ginge river diversions have revealed economic diamond grades. The corporation generates positive cash flow from its tailings operations, and it now plans to use portions of those cash flows to fund an exploration project on properties adjacent to its current f ...

Kwango River
The Cuango or Kwango ( pt, Rio Cuango) is a transboundary river of Angola and Democratic Republic of Congo. It is the largest left bank tributary of the Kasai River in the Congo River basin. It flows through Malanje in Angola. The Kwango River basin has large resources of diamonds in the Chitamba-Lulo Kimberlite Cluster in Lunda Norte Province, discovered in the main river channel and on flats and terraces in its flood plains. History The Rund Kingdom, which expanded to become the Lunda Empire, encompassed territory stretching from Kwango River to the Luapula River. Its rulers partook in the slave trade. Lunda's expansion in the valley promoted a common political and cultural heritage while also promoting slave trading, accounting for the low population densities between the Kwango and Kwilu rivers.Ogot, p.607 The Portuguese colonized the Kwango River valley and usurped the Kingdom of Kasanje. The Kwango River was subject to a Portuguese treaty signing in Lisbon on May 25, 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joint Venture
A joint venture (JV) is a business entity created by two or more parties, generally characterized by shared ownership, shared returns and risks, and shared governance. Companies typically pursue joint ventures for one of four reasons: to access a new market, particularly Emerging market; to gain scale efficiencies by combining assets and operations; to share risk for major investments or projects; or to access skills and capabilities. According to Gerard Baynham of Water Street Partners, there has been much negative press about joint ventures, but objective data indicate that they may actually outperform wholly owned and controlled affiliates. He writes, "A different narrative emerged from our recent analysis of U.S. Department of Commerce (DOC) data, collected from more than 20,000 entities. According to the DOC data, foreign joint ventures of U.S. companies realized a 5.5 percent average return on assets (ROA), while those companies’ wholly owned and controlled affiliates ( ...

Business Development
Business development entails tasks and processes to develop and implement growth opportunities within and between organizations. It is a subset of the fields of business, commerce and organizational theory. Business development is the creation of long-term value for an organization from customers, markets, and relationships. Business development can be taken to mean any activity by either a small or large organization, non-profit or for-profit enterprise which serves the purpose of ‘developing’ the business in some way. In addition, business development activities can be done internally or externally by a business development consultant. External business development can be facilitated through Planning Systems, which are put in place by governments to help small businesses. In addition, reputation building has also proven to help facilitate business development. Overview In the limited scholarly work available on the subject, business development is conceptualized as or relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economy
An economy is an area of the production, distribution and trade, as well as consumption of goods and services. In general, it is defined as a social domain that emphasize the practices, discourses, and material expressions associated with the production, use, and management of scarce resources'. A given economy is a set of processes that involves its culture, values, education, technological evolution, history, social organization, political structure, legal systems, and natural resources as main factors. These factors give context, content, and set the conditions and parameters in which an economy functions. In other words, the economic domain is a social domain of interrelated human practices and transactions that does not stand alone. Economic agents can be individuals, businesses, organizations, or governments. Economic transactions occur when two groups or parties agree to the value or price of the transacted good or service, commonly expressed in a certain currency. Ho ...

Tailings
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cash Flow
A cash flow is a real or virtual movement of money: *a cash flow in its narrow sense is a payment (in a currency), especially from one central bank account to another; the term 'cash flow' is mostly used to describe payments that are expected to happen in the future, are thus uncertain and therefore need to be forecast with cash flows; *a cash flow is determined by its time ''t'', nominal amount ''N'', currency ''CCY'' and account ''A''; symbolically ''CF'' = ''CF''(''t,N,CCY,A''). * it is however popular to use ''cash flow'' in a less specified sense describing (symbolic) payments into or out of a business, project, or financial product. Cash flows are narrowly interconnected with the concepts of value, ''interest rate'' and liquidity. A cash flow that shall happen on a future day ''t''N can be transformed into a cash flow of the same value in ''t''0. Cash flow analysis Cash flows are often transformed into measures that give information e.g. on a company's value and situat ...

River Terrace
Fluvial terraces are elongated terraces that flank the sides of floodplains and fluvial valleys all over the world. They consist of a relatively level strip of land, called a "tread", separated from either an adjacent floodplain, other fluvial terraces, or uplands by distinctly steeper strips of land called "risers". These terraces lie parallel to and above the river channel and its floodplain. Because of the manner in which they form, fluvial terraces are underlain by fluvial sediments of highly variable thickness.Fairbridge, R. W., 1968, ''Encyclopedia of Geomorphology.'' Reinhold Book Company, New York.Blum, M., and T.E. Tonqvist, 2000, ''Fluvial responses to climate and sea-level change, a review and look forward.'' Sedimentology. v. 47 suppl. 1, pp. 2-48. River terraces are the remnants of earlier floodplains that existed at a time when either a stream or river was flowing at a higher elevation before its channel downcut to create a new floodplain at a lower elevation.

Diamond
Diamond is a Allotropes of carbon, solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the Chemical stability, chemically stable form of carbon at Standard conditions for temperature and pressure, room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest Scratch hardness, hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of lattice defect, defects or impurities (about one per million of lattice atoms) color diamond blue (bor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lunda Norte Province
Lunda Norte ( en, North Lunda) is a province of Angola. It has an area of 103,760 km² and a population of 862,566. Angola's first President, Agostino Neto, made Lucapa the provincial capital after independence, but the capital was later moved to Dundo. The province borders the Democratic Republic of Congo in the northeast and Lunda Sul in the south. The province is rich in gold and diamonds, but remains vastly underdeveloped and impoverished. UNITA used the money generated from the sale of diamonds to fund war efforts. Cuango River valley, the richest diamond area of Angola is located in the province. Mining is done by notable companies like DeBeers and Endiama. The Lunda province whose capital was Saurimo was created by the Portuguese colonial empire on July 13, 1895. It was divided into Lunda-Sul and Lunda-Norte subdivisions through a constitution act in 1978 by the People's Movement for the Liberation of Angola (MPLA) government. Iron and manganese mining are also importa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mining Rights
Mineral rights are property rights to exploit an area for the minerals it harbors. Mineral rights can be separate from property ownership (see Split estate). Mineral rights can refer to sedentary minerals that do not move below the Earth's surface or fluid minerals such as oil or natural gas. There are three major types of mineral property; unified estate, severed or split estate, and fractional ownership of minerals. Mineral estate Owning mineral rights (often referred to as a "mineral interest" or a "mineral estate") gives the owner the right to exploit, mine, and/or produce any or all minerals they own. Minerals can refer to oil, gas, coal, metal ores, stones, sands, or salts. An owner of mineral rights may sell, lease, or donate those minerals to any person or company as they see fit. Mineral interests can be owned by private landowners, private companies, or federal, state or local governments. Sorting these rights are a large part of mineral exploration. A brief outline ...
