| Location and accuracy | The Bondholder mine is at the head of the north fork of Saint Patrick Creek at an elevation of about 1,250 feet. It is about 1.5 miles east of the top of Ester Dome. The Bondholder workings are at the north end of the Mohawk group of claims (FB061). The mine is locality 156 of Cobb (1972 [MF 410]). |
Geologic descriptionThe Bondholder vein was opened by at least two shafts and several pits (Hill, 1933, p. 146). About 200 feet north of these shafts, an opening exposed a 4.5-foot-wide vein in mica schist that was oriented N. 24 E., dipping 45 NW. The vein contained iron- and arsenic-oxide stained quartz, a sample of which assayed $10.29 gold per ton (0.5 ounce of gold per ton) (Hill, 1933, p. 146). The vein averaged 6 feet in thickness in a 142-foot shaft. By 1931, five hundred tons of ore had been mined from the Bondholder vein. | |
