full_context: Document 1: Toroparu mine: The Toroparu mine is one of the largest gold mines in the Guyana and in the world. The mine is located in the north-west of the country in Cuyuni-Mazaruni. The mine has estimated reserves of 6 million oz of gold.
Document 2: British Empire: Most of the UK's Caribbean territories achieved independence after the departure in 1961 and 1962 of Jamaica and Trinidad from the West Indies Federation, established in 1958 in an attempt to unite the British Caribbean colonies under one government, but which collapsed following the loss of its two largest members. Barbados achieved independence in 1966 and the remainder of the eastern Caribbean islands in the 1970s and 1980s, but Anguilla and the Turks and Caicos Islands opted to revert to British rule after they had already started on the path to independence. The British Virgin Islands, Cayman Islands and Montserrat opted to retain ties with Britain, while Guyana achieved independence in 1966. Britain's last colony on the American mainland, British Honduras, became a self-governing colony in 1964 and was renamed Belize in 1973, achieving full independence in 1981. A dispute with Guatemala over claims to Belize was left unresolved.
Document 3: Caribbean: Situated largely on the Caribbean Plate, the region comprises more than 700 islands, islets, reefs and cays. (See the list.) These islands generally form island arcs that delineate the eastern and northern edges of the Caribbean Sea. The Caribbean islands, consisting of the Greater Antilles on the north and the Lesser Antilles on the south and east (including the Leeward Antilles), are part of the somewhat larger West Indies grouping, which also includes the Lucayan Archipelago (comprising the Bahamas and Turks and Caicos Islands). The Lucayans and, less commonly, Bermuda, are also sometimes considered Caribbean despite the fact that none of these islands border the Caribbean Sea. In a wider sense, the mainland countries, regions, and territories of Belize, the Caribbean region of Colombia, Cozumel, the Yucatán Peninsula, Margarita Island, the Guyanas (Guyana, Suriname, French Guiana, Guayana Region in Venezuela, and Amapá in Brazil), are often included due to their political and cultural ties with the region.

Document 8: Secretariat of the Caribbean Community: The original home of the CARICOM Secretariat (and its precursor the CARIFTA Secretariat) was at Colgrain House (specifically the southern half of the building, while the northern half was used as the residence of the secretary-General) on Camp Street, Georgetown, Guyana. Ground was broken for a new CARICOM Secretariat headquarters on February 25, 1998, at Liliendaal/Turkeyen. Construction of the CARICOM Secretariat Headquarters Building commenced in May 2001 and on 19 February 2005 the building was officially commissioned in an inauguration ceremony. The building was officially handed over to the CARICOM Secretariat on 15 July 2005 and the secretariat commenced operations in the building on 26 July 2006.
Document 9: Bermuda: The PLP, the party in government when the decision to join CARICOM was made, has been dominated for decades by West Indians and their descendants. (The prominent roles of West Indians among Bermuda's black politicians and labour activists predated party politics in Bermuda, as exemplified by Dr. E. F. Gordon). The late PLP leader, Dame Lois Browne-Evans, and her Trinidadian-born husband, John Evans (who co-founded the West Indian Association of Bermuda in 1976), were prominent members of this group. They have emphasised Bermuda's cultural connections with the West Indies. Many Bermudians, both black and white, who lack family connections to the West Indies have objected to this emphasis.

Document 11: Caribbean Community: Established mainly by the English - speaking parts of the Caribbean, CARICOM has become multilingual in practice with the addition of Dutch - speaking Suriname on 4 July 1995 and French - and Haitian Kreyòl - speaking Haiti on 2 July 2002. Furthermore, it was suggested that Spanish should also become a working language. In July 2012, CARICOM announced that they were considering making French and Dutch official languages. In 2001, the heads of government signed a revised Treaty of Chaguaramas that cleared the way to transform the idea of a common market CARICOM into a Caribbean (CARICOM) Single Market and Economy. Part of the revised treaty establishes and implements the Caribbean Court of Justice.
Document 12: West Indies Federation: The West Indies Federation, also known as the West Indies, the Federation of the West Indies or the West Indian Federation, was a short-lived political union that existed from 3 January 1958 to 31 May 1962. Various islands in the Caribbean that were colonies of the United Kingdom, including Trinidad and Tobago, Barbados, Jamaica, and those on the Leeward and Windward Islands, came together to form the Federation, with its capital in Port of Spain, Trinidad and Tobago. The expressed intention of the Federation was to create a political unit that would become independent from Britain as a single state—possibly similar to the Canadian Confederation, Australian Commonwealth, or Central African Federation; however, before that could happen, the Federation collapsed due to internal political conflicts over how the Federation itself would be governed or how it would viably function. The territories that would have become part of the Federation eventually became the nine contemporary sovereign states of Antigua and Barbuda, Barbados, Dominica, Grenada, Jamaica, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, and Trinidad and Tobago; with Anguilla, Montserrat, the Cayman Islands, and Turks and Caicos Islands becoming British overseas territories. British Guiana (Guyana) and British Honduras (Belize) held observer status within the West Indies Federation.

The Federation was formed on 3 January 1958, and was formally dissolved on 31 May 1962.
