This report from DCO is a kind of review article. This article itself does not have specific reference papers cited. Just another review article. I think the DCO people expect us to dig around a little. Plus there are ~300 DCO scientists active in the group.
Per the article: there is a LOT of subsurface carbon - read living organisms - the estimates are large:
continental subsurface hosts are 2 to 6 × 10^29 cells.
Many of the species found come from solid rock with some stress fractures (because a lot the samples come from seismically active sites or from kilometers beneath the seabed.)
One interesting point is that many subsurface organisms spend little energy on growth, they simply exist. Evolution is in "standby":
