Stage 1 Complete, Stage 2 in progress. We have finished stage 1 of drilling, having gotten through the unstable part of the aquifer, and are now into stage 2 -- opening the hole to set casing. Casing will be set at around 980 feet below surface in massive basalts. We ended up kicking off into a new hole at 660 feet (Ki...mama 1B), which was cored with HQ to 996 feet. This new hole will be the one we continue drilling in after casing is set. The process of opening and casing hole will take a week to 10 days or so, depending on conditions. After the casing sets, we will begin coring with HQ again. Update: The sed layer at 182-201 m kept washing out, and the drillers ended up making a new hole at 201 m, so they went ahead cored that down to 300 m, by-passing the stuck drill rods. so we now have another 100 m of HQ core on deck. They completed prepping the hole yesterday and are now about 25 feet down or so with a rotary bit, opening to 16.5 cm. Best estimate for completing hole and casing, and starting to make core again is 23 October.
