"We are very pleased to be one of the first North American companies to
acquire exploration permits in Niger - a country that has not been explored
using modern techniques and has, until now, been one of the world's best-kept
uranium secrets," said Kabir Ahmed, Chairman and CEO of Northwestern.northwestmineral.

Mars Rovers Advance Understanding of the Red Planet

By operating eight times as long as planned, Spirit was able to climb
up those hills, examine a wide assortment of rocks and find mineral
fingerprints of ancient water.
