COBALT-BISMUTH: Fortune says new tests result in cleaner cobalt concentrate from NICO

NORTHWEST TERRITORIES – Based in London, Ont., Fortune Minerals says metallurgical tests have produced an upgraded, essentially arsenic free cobalt concentrate from the NICO cobalt-gold-bismuth-copper development project 160 km northwest of Yellowknife.

Tests successfully removed more than 99% of the arsenic in NICO bulk concentrate. The arsenic is then vitrified, creating a glass product that passes TCLP tests for safe disposal. Gold can be recovered from one concentrate; Fortune says this will allow it to control bullion sales. Separate cobalt and bismuth concentrates will be made and sold to third-party processors without incurring heavy penalties for arsenic.

Fortune has already received environmental approval for the NICO mine and concentrator in the Northwest Territories as well as its refinery in Saskatchewan.
