"Engineering summaries and longitudinal sections dated January 15, 1907 and May 16, 1908 of this portion of the Republica Vein reported an average 12 foot (3.66 m) vein width on the 300 foot level that assayed an average of 175 ounces per ton silver (5.99 kg/tonne Ag) along a 111 foot (33.8 m) horizontal length of the north drift. This section indicates that the Republica vein thickened to that depth, from a vein width of 1.66 metres near the surface."
