As Iran prepares for talks over its disputed atomic programme, it said on Saturday it had found significant new deposits of raw uranium and identified sites for 16 more nuclear power stations.
State news agency IRNA quoted a report by the Atomic Energy Organisation of Iran (AEOI) which said the reserves were discovered in northern and southern coastal areas and had trebled the amount outlined in previous estimates.
"We have discovered new sources of uranium in the country and we will put them to use in the near future," Fereydoun Abbasi-Davani, head of the AEOI, was quoted as saying at Iran's annual nuclear industry conference.
The announcement could be deciphered as Iran's strategy to bolster its negotiation power at talks in Kazakhstan on Tuesday with the United States, Russia, China, Britain, France and Germany. by talking up its reserves and nuclear ambitions, may hope
Diplomats say the six powers, known as the P5+1, are set to offer Iran some relief from international sanctions if it agrees to curb its production of higher-grade enriched uranium.
The West says Iran's enrichment of uranium to a fissile purity of 20 percent demonstrates its intent to develop a nuclear weapons capability, an allegation the Islamic republic denies.
Iran's reserves of raw uranium now stood at around 4,400 tonnes, taking into account discoveries over the past 18 months, IRNA quoted the report as saying.
In another sign that Iran is intent on pushing forward with its nuclear ambitions, the report also said 16 sites had been identified for the construction of nuclear power stations.
The exact locations was not specified but they included coastal areas of the Gulf, Sea of Oman, Khuzestan province and the Caspian Sea.
Iranian authorities have long announced their desire to build more nuclear power plants for electricity production. Only one currently exists, in the southern city of Bushehr, and that has suffered several shutdowns in recent months.
The announcements could further complicate the search for a breakthrough in Kazakhstan, after three unsuccessful rounds of talks between the two sides in 2012.
In what Washington has called a provocative move, Iran is also installing new-generation centrifuges, capable of producing enriched uranium much faster, at a site in Natanz in the centre of the country.
Western diplomats say the Six-power will reiterate demands for the suspension of uranium enrichment to a purity of 20 percent, the closure of Iran's Fordow enrichment plant, increased access for International Atomic Energy Agency inspectors and agreement to address concerns on existing uranium stockpiles.
In return, the latest embargoes on gold and metals trading with Iran would be lifted. Iran has criticized the offer and says its rights need to be fully recognized. Suggestions were earlier made that Iran transfers its enriched uranium to Russia and in return it gets tghe 20% purity needed for medical isotopes.
"If the Six-power group wants to start constructive talks with Tehran it needs to present a valid proposal," said Jalili. "It needs to put its past errors to one side ... to win the trust of the Iranian nation." Ayatollah Khameini had earlier rejected direct talks with Washington saying "it is holding a gun against Iran."
In a statement issued before the Iranian announcement, German Foreign Minister Guido Westerwelle said the Six-power group wanted to enter a 'substantial negotiation process' over Tehran's nuclear programme.
