(a) Plot the locations of the drill holes utilizing a suitable grid pattern.

(b) Plot a vertical section of the drill holes located along 400 E.

(c) Calculate the drill hole composites for the holes located along sections 600 E and 200 N.

(d) Determine the area of influence of drill hole # 6.

(e) Determine the volume of material that is influenced by drill hole # 6.

(f) Determine the mineral content of the material that is influenced by drill hole # 6 if the tonnage factor is 0.02 m3/tonne.
