We present results from simulations of static-light mesons on 2+1 flavour Domain Wall Fermion lattices with a (2fm)3 spatial volume. We obtain the decay constants and Δ B=2 weak matrix elements for the B and Bs mesons and the corresponding ratio ξ=fBs√BBs/fB√BB which relates the measured mass differences to the ratio of CKM matrix elements |Vts|/|Vtd|.
