Because proven reserves include oil recoverable under current economic conditions, nations may see large increases in proven reserves when known, but previously uneconomic deposits become economic to develop. In this way, Canada's proven reserves increased suddenly in 2003 when the oil sands of Alberta were seen to
COMEBU carried out exploration work in 2003–2004 which showed proven reserves of 1,908 tonnes of coltan, probable reserves of 2,504 tonnes and possible reserves of 5,000 tonnes. [21] On 6 January 2022 Ibrahim Uwizeye, Minister of Hydraulics, Energy and Mines, announced that COMEBU was the only active mining company in Burundi. The activities ...

The main source of niobium until now has been from the ore mineral columbite that is extracted widely in Canada, Brazil, Australia and Nigeria, with China obtaining nearly 95 per cent of the ...
Ferroniobium is an important iron-niobium alloy, with a niobium content of 60-70%. [1] It is the main source for niobium alloying of HSLA steel and covers more than 80% of the worldwide niobium production. The niobium is mined from pyrochlore deposits and is subsequently transformed into the niobium pentoxide Nb 2 O 5.
The Motzfeldt mine is a large niobium mine located in southern Greenland in Kujalleq. Motzfeldt represents one of the largest niobium reserves in Greenland having estimated reserves of 130 million tonnes of ore grading 1% niobium and 0.04% tantalum.
