100,000 tons grading 1oz/ton gold :-)RADCLIFF
• Historical production of 14,000 tons produced 14,500 ounces of gold.
– Only oxide ore was mined
• Mine did not receive any further development until 1989.
• In 1992, Echo Bay Exploration optioned the property and continued the exploration of
the site and extensively drilled the property.
– A drill program of 87 drill holes spaced 140 feet for a total of 16,806.5 feet
delineated the current ore body being developed by Pruett Ballarat Inc.
• The most recent historical resource estimate was conducted by Echo Bay
Exploration in 1993. It was estimated that there were 1,148,978 tons grading 0.244
ounce per ton gold for a total of 280,350 in situ ounces of gold.*
– Estimate was based on a 0.07 oz/ton gold cut-off and a 2oz/ton gold high-grade cut-off
– Stated by Pruett Ballarat Inc. that the modeled data demonstrated a high-grade zone of 100,000 tons grading 1oz/ton gold.
