The Leland is a prominent vein that crops out over the summit of Leland Hill and extends SE-ward through the Swiss-American and Golconda Mines to a junction with the Pioneer vein at the abandoned Treadwell shaft. The general strike of the vein is about 30º south of east, and the dip 70ºSW. The vein is one of a group of many branching lodes, among which are the Pioneer, Lilah, Gold Dust, and Boundary Cone veins. On Leland Hill the members of this group converge westward and disappear at or near the contact between the Alcuone Trachyte and the Oatman Andesite, on the west slope of the hill.
The vein is a stringer lode with no gouge and no definite walls. The vein material is the usual quartz-calcite aggregate of the Oatman veins.
This vein is reported to have yielded about 4,500 tons of ore in 1903 and 1904 from stopes worked through tunnels in Leland Hill.
