Greater Axacan and adjoining Allegheny Mountains' western slopes, Mocosa, to Ajacal (Avacal) was thought to have rivers connecting to the south and west seas at that time. It was due to what the Spanish viewed as trespassing that had brought about the order for the monks to support the Virginia mining efforts. Hernando Moyano and Juan Pardo prospected through the Cherokee range in 1566-67 and barely sufficient reports suggest mining continued into the 1690s along the Appalachian Mountain range. These had routed by land. The explorers had discovered the curiosity of interior oil springs, copper outcrops, iron ore and coal for forging. All of which were located towards the Allegheny Mountains and Unaka Range also in the province of Axacan and the northern areas of "La Floridia" as spelled on 16th-century Spanish maps. North of "The Florida" at today's Virginia was called "Land of Don Luis" by later half 16th-century Spanish.
