The Tevatron collider experiments have a proven track record for making significant B physics measurements. The hadronic environment provides for the production of B species not readily accessible to the B-factories. One of these states, the Bs meson, is of particular interest. I will report on studies of this meson by the DZero experiment using 1 fb-1 of data. Measurements of the Bs lifetime and lifetime difference, and the first direct upper and lower bounds on the Bs mixing frequency (Delta ms) will be presented. Our measurement of the CP violation parameter in B0 mixing and decay will also be shown.
