In support of the neutron electric dipole moment (EDM) experiment at TRIUMF, we are developing a $^{129}$Xe/$^{199}$Hg dual-comagnetometer that can monitor the magnetic field drift and reduce the uncertainties arising from geometric phase effects caused by inhomogeneous fields. Using UV light sources, we will excite transitions in $^{129}$Xe and $^{199}$Hg suitable for detection of their spin precession. Initial spin polarization of these species will be achieved via optical pumping. This talk will report our current status and future plans.
