At point A, planar gold/quartz lode outcrops at an elevation of 410 m above sea level. This same horizon outcrops at point B, elevation 210 m. At point C (elevation 800 m), a vertical diamond drill hole penetrated this lode at a depth of 470 m below ground level. The distance (in plan) from A to B is 500 m, direction N60E. The distance (in plan) from B to C is 320 m, direction S10W. Use a scale of 1 cm = 50 m and sketch your solution below. Find: (a) the true orientation of the lode, and (b) the apparent dip of the lode towards 090
