Progress has been slow due to the highly fractured nature of the rock we are trying to drill through and some equipment problems. We recovered another run of core today, after fixing the diesel engine's alternator. Our current issue is that core fragments have fallen out of the bottom of the core barrel as it was brought to the surface. We have to use a spear tool to clear out the drill string before the next core barrel will be able to rest behind the bit at the bottom of the hole. Coring should resume again this evening.
