$PGVI ~$$$~ Early in 1981, McMillan optioned the claims to Warburton Minerals Inc. which added the RIVER 1-68 claims. Warburton further added the River 69-76 claims in July 1983, resulting in a block roughly similar in coverage to the present PHIL 1-93 claim block. Also in 1983, Warburton conducted a surface geological mapping and geochemical sampling program. A sample of the “Main Zone” taken during this program returned a value of 1,817 g/t silver (58.6 oz/ton) and 4.6% copper. Warburton also conducted airborne magnetic and electromagnetic (EM) surveying over the entire property in October 1983. The airborne survey served to identify the center of the intrusion on the property.
