    8. After crossing the river, walk along the bank of the river until you reacha sign explaining about the remains of the mine.
    9. Destination reached.


The remains of the mine are located a little off the river, but by searching around the bank of the river, you will find a 2 meter sized rock. By examining the rock, you will find small octahedron sparkles. By hitting these sparkles with your sledge hammer it will spark and omit a sulfurous odour. From these facts we determined that these sparkles were pyrite.
