There is only a small downward vertical force on the mantel from its own weight.
If you have a router you can cut recesses in the back surface of the mantel and mount flat metal plates with keyhole shaped slots in them.
Then you put two screws with anchors in the masonry and have the screw heads stick out slightly. The large hole part of the keyhole goes over the screwhead and when you push down on the mantel (mantle?) it tightens against the wall as the screw shaft goes up the elongated slot part of the fastener.
Using more than two screws will result in only two of the screws bearing the load.
