The principal mines of this region are 7 miles SE. from Gusa, and about 4 miles in a direct line from the seacoast. Gusa is a small town on the north coast of Mindanao, 4 miles east from Cagayan, the capital of the province of Misamis. The mines are reached by steep, narrow trails over ridges varying in altitude from 1100 to 1600 feet above sealevel. The whole region is covered with a thick growth of tall grass, except a few spots on the sides of some of the hills, where there are patches of timber and jungle.
