"The first direction of cooperation is the prospecting and production of natural uranium," said Sergei Kiriyenko, who is in Brazil to lead the Russia Days events.
Kiriyenko said 25-30% of Brazil's territory had been surveyed at shallow depths for uranium deposits, and even such a limited search showed reserves of 350,000 tons, putting Brazil sixth globally.
"We have a firm conviction that if modern technologies were used here [and Russia has deep prospecting technologies], then natural uranium reserves in Brazil could be increased by many times, at least threefold but possibly five- or tenfold," he said.
Kiriyenko also said the two countries could cooperate in the nuclear sphere.
Touching upon the power transmission problem, he said Brazil has "a very big interest in low-temperature conductors," while Russia is a world leader in superconducting technologies and is ready to share its experience.
Kiriyenko said Russian-Brazilian trade would soon exceed $10 billion annually.
