Mike Kushy, solo. Took in drill and a BDH of cement. Finished off breaking down the boulder from Wednesday and put the pieces aside. Then a mix was made using 1 Daren Drum of sand and 1/4 drum of cement. This was used in and around the vertical squeeze boulder (unfortunately this boulder can not be removed as it holds up loads above), the vertical squeze boulder will have to be widened later. Went to surface with empty bags and drums then brought back in 2 drums of sand and some more water to mix with. This again was turned into cement and used at the base of the vertical squeeze rock. 3/4 BDH of cement and 2.5l of water left in cave, no sand. Should be safe enough now to open up the light conncetion route to the chamber, but I'd like to see another session of cement work yet. Would be nice to build a wall to the ceiling just above said squeeze. 5 hours. Mike.
