Results in the quenched approximation for SU(3) breaking ratios of theheavy-light decay constants and the $\Delta F=2$ mixing matrix elements arereported. Using lattice simulations at $6/g^2=5.7$, 5.85, 6.0, and 6.3, wedirectly compute the mixing matrix element $M_{hl}=< \bar P_{hl}|\bar h\gamma_\mu (1-\gamma_5)l \bar h \gamma_\mu(1-\gamma_5)l|P_{hl}>$. Extrapolatingto the physical B meson states, $B^0$ and $B_s^0$, we obtain $M_{bs}/M_{bd}=1.76(10)^{+57}_{-42}$. in the continuum limit. The systematic error includesthe errors within the quenched approximation but not the errors of quenching.We also obtain the ratio of decay constants,$f_{bs}/f_{bd}=1.17(2)^{+12}_{-6}$. For the B parameters we find $B_{bs}(2GeV)=B_{bd}(2 GeV)=1.02(13)$; we cannot resolve the SU(3) breaking effects inthis case.Comment: 16 pages, 5 ps figures, Late
