4 P.M. Drilled 570' to 600' - easy drilling & cutting have higher proportion of fine fragments (1/8" and smaller). Some loss of drilling mud & mud being built up at end of day shift. Drill stopped at 600' to build up mud and prepare to take core.

8:29 - 8:59 P.M. - Took core with 6 1/8" (OD.) X 3 1/2" (I.D.) diamond bit & double core barrel. Driller (Bill Springer) says drill acted like material was porous & had small cavities. (See Driller's coring report.)
