Demonstration heap leaching

The mineralogical studies done on Hope Brook ore samples indicated that a heap leach gold recovery process may be possible. In the metallurgical program that followed, column tests confirmed this interpretation. A 9300 tonne demonstration heap leach test, in the late fall of 1985, reaffirmed laboratory results while identifying operating conditions that will have to be addressed in a production heap leach plan. Operating plans, gold recoveries and cost areas will be presented.
Another important factor in a successful operation is the environment approach.
