NOTE: Rods seized in hole at 50-ft. Drill Rig down from 12/16/06 to 1/1/2007. New hole (1B-07-26A) was drilled 2-ft. from original (1B-07-26).

Core from the original location is contained in Box 2. Box 3 contains the first run of new hole (45 to 50-ft.).

Comparison between the overlapping runs show great variation. Material from the original hole (1B-07-26) is quartzite as described at 41.1-ft, in new hole (1B-07-26A) is granodiorite.
