Rhythmically banded mudstone and siltstone from the bottom of hole 19OMS-003. Irving believes these rocks are part of the Mesozoic basement underlying the Tertiary volcanic rocks of the region. If so, the geology is similar to that at the Hishikari gold deposit where Mesozoic basement rocks below Tertiary volcanic rocks host a vast network of high-grade veins. Irving is excited by this prospect.
