Search teams have located the wreckage of a small plane carrying 11 people, including six top executives of an Australian mining firm, that disappeared over the weekend in west Africa.

The missing plane was found Monday afternoon in dense jungle inside the Republic of Congo, Cameroon's government spokesman, Issa Tchiroma Bakary, said Monday.

No survivors were found. 

In addition to the six Australians, there were two French, an American and two Britons on board. The aircraft, chartered by Australian company Sundance Resources Ltd., disappeared Saturday half an hour after it left Cameroon's capital, Yaounde. The plane was flying to Yangadou in the Republic of Congo, where company officials were to visit an iron ore mining site.

A statement from the company said six of the firm's top executives were on board, including Geoff Wedlock, chair of Sundance Resources, and Don Lewis, the CEO.

The search was co-ordinated by Cameroon, Gabonese and Republic of Congo authorities with support from Australian, Canadian and U.S. foreign officials, the company said.

Sundance Resources asked the Australian Stock Exchange to suspend the company's shares before trading opened Monday.

Sundance executives had been in Cameroon in recent days to meet with officials about the company's Mbalam project, which the official said could earn Cameroon billions of dollars over 25 years.

Sundance has a 90 percent stake in Cameroon Iron Ore Co. (Camiron S.A.), which owns more than 1,800 square kilometres of fields with estimated reserves of nearly two million tonnes of mineral resources.
