FNX Mining Company Inc.

FNX is an emerging mid-tier Canadian mining company exploring, developing and profitably re-opening former producing nickel-copper-platinum-palladium-gold mines in Canada's historic Sudbury mining district. The first year of commercial operation at its Phase 1 McCreedy West Mine generated revenues of $55.9 million and $6.5 million in net income. Phase 1 capital was repaid in less than a year.

FNX has $63 million in cash and no debt, sufficient to bring the PM Deposit and Levack Mine into production in 2005 and 2006, respectively, and to finance the Podolsky Property advanced exploration program. The $11.4 million 2005 exploration program is focused on new exploration targets and more than half is committed to footwall exploration. This initiative has already been rewarded with a high grade footwall discovery, located below the Levack Mine. Further testing of the two massive sulfide veins and associated strong UTEM off-hole conductor will be a priority in 2005. In addition, FNX acquired Aurora Platinum’s extensive land holdings in Sudbury in June, which increased its land holdings eightfold.  An aggressive exploration program will be initiated shortly on the Aurora properties.
