In geology a fault, or fault line, is a planar fracture in rock in which the rock on one side of the fracture has moved with respect to the rock on the other side. Large faults within the Earth's crust are the result of differential or shear motion and active fault zones are the causal locations of most earthquakes. Earthquakes are caused by energy release during rapid slippage along a fault. A fault that runs along the boundary between two tectonic plates is called a transform fault.

Since faults do not usually consist of a single, clean fracture, the term fault zone is used when referring to the zone of complex deformation that is associated with the fault plane. The two sides of a non-vertical fault are called the hanging wall and footwall. By definition, the hanging wall occurs above the fault and the footwall occurs below the fault. This terminology comes from mining. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall hanging above him..........Keeping this in mind, Dale referred more than once in our last deep drilling news release, that the 96 vein was extended towards the hangwall and dipping down towards the footwall ,...he also talked about the wide true withds of a large new vein heading North and down towards the footwall. I beleive one can view this vein on pg 183 od ACA Howe 2004 report. Using the map scale this north vein is at least 700 x 800 ft and Dale says true mining width of around 16 ft which is right according to the map scale. The map shows at least 3 to 4 more to be found and the grading is proving to be very profitable in the future. We know San has at least 4 kil of Sam Norm and it will be interesting what we find below the footwall.Traps7
