The ground state of homogeneous, superfluid -–normal- mixtures is studied by Fixed-Node Diffusion Monte Carlo simulations. The condensate fraction of the component only depends on the concentration through its effect on the average density. Slight deviations of the structural properties from previous variational results, obtained within the Average Correlation Approximation (ACA), are discussed. The momentum distribution and effective mass of the Fermi () component are also calculated.
