Following West Copper Corp’s acquisition of the property within the September/1996 the organization set about combining the home under one proprietor.

This led to an overall total reduction of the new tonnage claimed to possess the newest measured and you can inferred categories when comparing to opinions advertised in the the fresh 2004 funding guess.
The latest 2008 pre-feasibility data along with incorporated the first NI 43-101 nutrient set aside imagine to your Local casino project. The new set aside estimate lies in gap framework while the exploit production schedule developed in the new pre-feasibility data and that is advertised while the a mill ore put aside and you may bunch leach put aside.

The fresh leached limit/oxide silver area (making use of their an excellent 0.40 grams/t gold cutoff) currently servers a supplementary thirty-two mil tonnes out of joint measured and you can conveyed tips.
