Question: What percent of the world's uranium oxide is produced by the country that claims the place Horse Block is located, other than Britain?

full_context: Document 1: British Empire: Britain retains sovereignty over 14 territories outside the British Isles, which were renamed the British Overseas Territories in 2002. Some are uninhabited except for transient military or scientific personnel; the remainder are self-governing to varying degrees and are reliant on the UK for foreign relations and defence. The British government has stated its willingness to assist any Overseas Territory that wishes to proceed to independence, where that is an option. British sovereignty of several of the overseas territories is disputed by their geographical neighbours: Gibraltar is claimed by Spain, the Falkland Islands and South Georgia and the South Sandwich Islands are claimed by Argentina, and the British Indian Ocean Territory is claimed by Mauritius and Seychelles. The British Antarctic Territory is subject to overlapping claims by Argentina and Chile, while many countries do not recognise any territorial claims in Antarctica.
Document 2: British Isles: There are two sovereign states in the isles: Ireland and the United Kingdom of Great Britain and Northern Ireland. Ireland, sometimes called the Republic of Ireland, governs five sixths of the island of Ireland, with the remainder of the island forming Northern Ireland. Northern Ireland is a part of the United Kingdom of Great Britain and Northern Ireland, usually shortened to simply the United Kingdom, which governs the remainder of the archipelago with the exception of the Isle of Man and the Channel Islands. The Isle of Man and the two states of the Channel Islands, Jersey and Guernsey, are known as the Crown Dependencies. They exercise constitutional rights of self-government and judicial independence; responsibility for international representation rests largely upon the UK (in consultation with the respective governments); and responsibility for defence is reserved by the UK. The United Kingdom is made up of four constituent parts: England, Scotland and Wales, forming Great Britain, and Northern Ireland in the north-east of the island of Ireland. Of these, Scotland, Wales and Northern Ireland have "devolved" governments meaning that they have their own parliaments/assemblies and are self-governing with respect to certain areas set down by law. For judicial purposes, Scotland, Northern Ireland and England and Wales (the latter being one entity) form separate legal jurisdiction, with there being no single law for the UK as a whole.
Document 3: Uranium mining in Australia: Radioactive ores were first extracted at Radium Hill in 1906, and Mount Painter in South Australia in the 1930s, to recover radium for medical use. Several hundred kilograms of uranium were also produced. Of the world's proven estimated uranium reserves (5,404,000 tonnes), 31% are held in Australia (1,673,000 tonnes), ahead of the second largest, Kazakhstan (12.1% or 651,800 tonnes). In terms of production, Canada is the largest supplier to export markets, followed by Kazakhstan and Australia. Uranium mined in Australia is mainly for export. Australia exported 50,235 tonnes of uranium oxide concentrate in the five years to 2008, worth A $2.9 billion.
Document 4: Split Island, Falkland Islands: Split Island is one of the Falkland Islands. It is near West Falkland, to its west, at the mouth of King George Bay. It is to the west of Rabbit Island, Hummock Island and Middle Island. It is north of the Passage Islands and south east of Westpoint Island, and south west of the Byron Heights and Storm Mountain.
Document 5: Stackpole Rocks: Stackpole Rocks is a group of rocks, the largest of them linked by a spit to the east extremity of South Beaches in Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica. The area was visited by early 19th century sealers.
Document 6: British Empire: Britain retains sovereignty over 14 territories outside the British Isles.   In 1983, the British Nationality Act 1981 renamed the existing Crown Colonies as "British Dependent Territories", and in 2002 they were renamed the British Overseas Territories. Three are uninhabited except for transient military or scientific personnel; the remaining eleven are self-governing to varying degrees and are reliant on the UK for foreign relations and defence. The British government has stated its willingness to assist any Overseas Territory that wishes to proceed to independence, where that is an option, and three territories have specifically voted to remain under British sovereignty (Bermuda in 1995, Gibraltar in 2002 and the Falkland Islands in 2013).British sovereignty of several of the overseas territories is disputed by their geographical neighbours: Gibraltar is claimed by Spain, the Falkland Islands and South Georgia and the South Sandwich Islands are claimed by Argentina, and the British Indian Ocean Territory is claimed by Mauritius and Seychelles. The British Antarctic Territory is subject to overlapping claims by Argentina and Chile, while many countries do not recognise any territorial claims in Antarctica.Most former British colonies and protectorates are among the 52 member states of the Commonwealth of Nations, a non-political, voluntary association of equal members, comprising a population of around 2.2 billion people. Sixteen Commonwealth realms voluntarily continue to share the British monarch, Queen Elizabeth II, as their head of state. These sixteen nations are distinct and equal legal entities – the United Kingdom, Australia, Canada, New Zealand, Antigua and Barbuda, The Bahamas, Barbados, Belize, Grenada, Jamaica, Papua New Guinea, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Solomon Islands and Tuvalu.

Document 8: Namibia: Providing 25% of Namibia's revenue, mining is the single most important contributor to the economy. Namibia is the fourth largest exporter of non-fuel minerals in Africa and the world's fourth largest producer of uranium. There has been significant investment in uranium mining and Namibia is set to become the largest exporter of uranium by 2015. Rich alluvial diamond deposits make Namibia a primary source for gem-quality diamonds. While Namibia is known predominantly for its gem diamond and uranium deposits, a number of other minerals are extracted industrially such as lead, tungsten, gold, tin, fluorspar, manganese, marble, copper and zinc. There are offshore gas deposits in the Atlantic Ocean that are planned to be extracted in the future. According to "The Diamond Investigation", a book about the global diamond market, from 1978, De Beers, the largest diamond company, bought most of the Namibian diamonds, and would continue to do so, because "whatever government eventually comes to power they will need this revenue to survive".
Document 9: River Island, Falkland Islands: River Island is one of the Falkland Islands. It is located in Byron Sound to the south of East Island and Pebble Island. There is a tidal island to its west, separated by a shallow lagoon.
Document 10: Saint Helena: There are several rocks and islets off the coast, including: Castle Rock, Speery Island, the Needle, Lower Black Rock, Upper Black Rock (South), Bird Island (Southwest), Black Rock, Thompson's Valley Island, Peaked Island, Egg Island, Lady's Chair, Lighter Rock (West), Long Ledge (Northwest), Shore Island, George Island, Rough Rock Island, Flat Rock (East), the Buoys, Sandy Bay Island, the Chimney, White Bird Island and Frightus Rock (Southeast), all of which are within one kilometre (0.62 miles) of the shore.

Document 12: Overseas military bases of the United Kingdom: The United Kingdom is still considered and remains a global power even into the 21st century; this is evidenced through the nation's 15 overseas military bases, making it second only to the United States in terms of total overseas bases worldwide. Currently, there is also the possibility of an additional two new bases being built in Oman and the United Arab Emirates in the near future. Note that both the United Arab Emirates and Oman were once under British rule, showing the impact of colonialism and the British armed forces military presence across the globe, even into the 21st century.
Document 13: Uranium: In 2005, seventeen countries produced concentrated uranium oxides, with Canada (27.9% of world production) and Australia (22.8%) being the largest producers and Kazakhstan (10.5%), Russia (8.0%), Namibia (7.5%), Niger (7.4%), Uzbekistan (5.5%), the United States (2.5%), Argentina (2.1%), Ukraine (1.9%) and China (1.7%) also producing significant amounts. Kazakhstan continues to increase production and may have become the world's largest producer of uranium by 2009 with an expected production of 12,826 tonnes, compared to Canada with 11,100 t and Australia with 9,430 t. In the late 1960s, UN geologists also discovered major uranium deposits and other rare mineral reserves in Somalia. The find was the largest of its kind, with industry experts estimating the deposits at over 25% of the world's then known uranium reserves of 800,000 tons.
