Diamcor Mining announced that following its previous release on the initial tender of 2,606.50 carats of rough diamonds, it delivered an additional 5,335.83 carats before the end of October.
The extended plan increases the mine life by two years, raising production to 372,000 oz. gold per year and all-in sustaining costs to US$703 oz. gold per year.
Experts believe the US firm could achieve $300 million in operating and cost savings from combining its mines in Nevada with those of the Canadian rival.
