2005

December

Updated feasibility study estimated gold reserves[1] (fourth quarter 2005) of 2,890,000 ounces situated within closely-spaced, near surface deposits. Open pit production estimated at 330,000 ounces per year with total cash costs estimated at US$201 per ounce over an 8.1 year mine life.
