Comments on the geologic information

  • Geologic Description = In 1996, Freegold Recovery Inc. outlined a +5,000 foot long multi-element soil anomaly on the Goose Creek prospect (Freeman and others, 1998). The core of the grid, covering an area approximately 2,000 feet by 1,000 feet, averaged over 100 ppb gold, three times the mean gold value over the project area. This anomaly trends N 80 W and was extended to a length of +10,000 feet in 1997. The anomaly is located in lower plate rocks of the Fairbanks Schist and appears to have secondary anomalies associated with district scale northeast trending structures similar to those on the Cleary Hill (ARDF no. LG119), Dolphin (ARDF no. LG112) and Wolf Creek (ARDF no. LG138) prospects. Initial drilling in late 1997 consisted of 5,038 feet of reverse circulation drilling in 11 holes. Preliminary assay results from one hole returned intercepts averaging up to 0.118 ounces of gold per ton over 160 feet in highly sericitized chlorite schist cut by 10-20% white quartz veins. Anomalous gold is associated with anomalous As, Sb, Pb, Ag, and Zn. Pyrite is relatively abundant in the sericitic alteration envelope but does not appear to be correlative with gold values. In 1998, 10 reverse circulation holes totaling 5,017 feet were drilled in the Goose Creek prospect to determine the extent and geometry of the higher grade intercepts encountered in the 1997 drill program. Results indicate that mineralization is controlled by an 85 degree south dipping structure. The gold-bearing alteration envelope around this structure is restricted in size indicating limited potential for bulk tonnage mineralization in this area.

Comments on the workings information

  • Workings / Exploration = Soil sampling in 1996 lead to the discovery of a multi-element soil anomaly more than 5,000 feet long. Initial drilling in late 1997 consisted of 5,038 feet of reverse circulation drilling in 11 holes. In 1998, 10 reverse circulation holes totaling 5,017 feet were drilled (Freeman and others, 1998).
