This deposit contains 10,000 toperhaps 20,000 tons. The work of getting this ore to the coast involves a difficult problemin transportation. The gorge of Saltadero Creek is too narrow and wind-ing, and in places too steep, to permit the construction of any kind ofroad except at great expense, and even if a road could be built down tothe mouth of Yamaniguey River it is doubtful whether steamers of properdraft could enter Canete Bay. The only feasible plan appears to be. Fig. 8.—Boulders of chrome ore in Saltadero Creek 300 ft. vertically BELOW orebody ON PoTOSI CLAIM. that of constructing an aerial tramway, about 3 mi. ( km.) long, fromthe deposit over the mountain and down to a point on the coast 2 mi.( km.) southeast of Canete Bay, from which a cart road or light tram-way may be built 9 mi.

It is reported to be owned byTomas Gomez of Baracoa, Cuba, and is said to have been denouncedoriginally as iron ore. There is no road to the claim at present, but onecould easily be constructed.
