2. THE PAST &Approximately 300,000 years ago mankind commenced exploration for rocks with specific characteristics to make tools. &Mining was the 1 st embryonic science? &Evolution of this science has continued throughout history and still continues. &Approximately 300,000 years ago mankind commenced exploration for rocks with specific characteristics to make tools. &Mining was the 1 st embryonic science? &Evolution of this science has continued throughout history and still continues.

3. MINING HISTORY &Gold mining commenced approx. 8,000 years ago. &Copper was smelted at least 6,200 years ago. &Early exploration involved finding alluvial deposits or outcropping ore bodies in stream head waters. &Gold mining commenced approx. 8,000 years ago. &Copper was smelted at least 6,200 years ago. &Early exploration involved finding alluvial deposits or outcropping ore bodies in stream head waters.

4. MINING HISTORY &In Roman times mineral deposits were mined to depths of up to 200m using slaves, fire and dewatering techniques. &Gold at this time was valued at ~US$2,000/oz. &The decline of the Roman Empire coincided with the diminishing mining reserves and the ability to pay the Legionnaires. &In Roman times mineral deposits were mined to depths of up to 200m using slaves, fire and dewatering techniques. &Gold at this time was valued at ~US$2,000/oz. &The decline of the Roman Empire coincided with the diminishing mining reserves and the ability to pay the Legionnaires.
