02/15/2000 (R Tuomi) - 1947 drilling contained several gold enriched zones in several of the 10 holes drilled. The best results were found in holes #2 and #3. DDH 2 assayed 0.04 ounce gold per ton over 0.3 foot (1.37 g/t Au over 0.09 m) at a depth of 104.7 feet. DDH 3 assayed 0.08 ounce gold per ton over 2.6 feet (2.74 g/t Au over 0.79 m) at a depth of 272.5 feet. The Ryan-Lundberg West occurrence is located 488 m (1600 ft) west of the Ryan-Lundberg East occurrence and may be an extension of the latter zone.
