  We extend results on robust exponential mixing for geometric Lorenz
attractors, with a dense orbit and a unique singularity, to singular-hyperbolic
attracting sets with any number of (either Lorenz- or non-Lorenz-like)
singularities and finitely many ergodic physical/SRB invariant probability
measures, whose basins cover a full Lebesgue measure subset of the trapping
region of the attracting set. We obtain exponential mixing for any physical
probability measure supported in the trapping region and also exponential
convergence to equilibrium, for a $C^2$ open subset of vector fields in any
$d$-dimensional compact manifold ($d\ge3$).
