3: (a) What is Taylors Rule of Thumb or Taylors Law for determining optimum mine life and why is there a need for this kind of rule of thumb?

(b) How can the optimum mine life (as determined by Taylors Law in (a) above) be used to determine the consequent optimum daily production rate.

(c) What is the simple rule of thumb for determining an optimum rate of production for underground mines?

(d) How might you apply this concept (in 3(c) above) to the preliminary evaluation of exploration properties which are targeting gold veins?

(e) When describing a mines production rate what does this actually mean? Why might it be different to the mines overall rate of mining?
