  New measurements of the z~6 intergalactic CIV abundance are presented, using
moderate resolution IR spectra of two QSOs taken with GNIRS on Gemini South.
These data were systematically searched for high redshift CIV absorption lines,
using objective selection criteria. Comprehensive tests were performed to
quantify sample incompleteness, as well as the rate of false positive CIV
identifications. The trend of constant $\Omega_{CIV}(z)$ observed at z~2-5
appears to continue to z~6, the highest observed redshift. The CIV sample is
also consistent with the redshift-invariant form of the CIV column density
distribution reported by Songaila (2001) at lower redshift, although with
fairly large uncertainties due to a smaller sample size and noisier infrared
data. The constant value of $\Omega_{CIV}$ does not necessarily imply that the
IGM was infused with an early metallicity ``floor,'' but the presence of early
CIV does indicate that heavy-element enrichment began < 1 Gyr after the Big
Bang. The lack of a decline in $\Omega_{CIV}$ at high redshift may indicate
that integrated CIV measurements are sensitive to the instantaneous rate of
feedback from galaxy formation at each epoch. Alternatively, it could result
from a balance in the evolution of the intergalactic gas density, ionization
conditions, and heavy-element abundance over time.
