Comments on the geologic information

  • Geologic Description = The country rock in the area of this site is the Triassic Texas Creek Granodiorite, which is locally intruded by apophyses of Eocene Hyder Quartz Monzonite (Smith, 1977; Berg and others, 1977, p. 17-18). ? Buddington (1929, p. 101) describes the Morning deposit as a quartz vein 2-4 feet thick in Texas Creek Granodiorite. The vein contains much pyrite and sparse pockets of galena.? the vein described by Buddington was not found during U.S. Geological Survey-U.S. Bureau of Mines field investigations in 1972-73 (Berg, 1977, p. 84-85). Instead, massive quartz float on the property was sampled and assayed 280 ppm Cu, 4000 ppm Pb, 120 ppm Zn, and 15 ppm (0.4 oz/ton) Ag.? Lead-isotope studies of galena from the Lakeside prospect (Maas and others, 1995, p. 229-248) indicate that the deposit is Eocene in age, contemporaneous with emplacement of the Hyder Quartz Monzonite.
  • Age = Lead-isotope studies of galena from the Lakeside prospect (Maas and others, 1995, p. 229-248) indicate that the deposit is Eocene in age, contemporaneous with emplacement of the Hyder Quartz Monzonite.

General comments

Subject category Comment text
Deposit Model Name = Polymetallic veins
Deposit Other Comments = the Morning prospect (Buddington, 1929, p. 101), was probably relocated as the Lakeside prospect (Berg and others, 1977, p. 38-39), and was covered in 1970 by the Lone Star group of 32 claims.
