|Location and accuracy||The Silver Bell prospect is in Section 11 at an elevation of about 4600 feet on a south-facing mountainside overlooking the West Fork of Texas Creek, about 2.5 miles northeast of the outlet of Texas Lake (Elliott and Koch, 1981, p. 14, loc. 46). The location is accurate to within about a quarter of a mile.|
The country rocks in the area of the Silver Bell prospect are pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group, which is underlain and locally intruded by the Triassic Texas Creek Granodiorite; and the Eocene Hyder Quartz Monzonite, which intrudes the Hazelton and Texas Creek rocks (Smith, 1977; Koch, 1996).
The deposit (Buddington, 1929, p. 44, 97) is a quartz fissure vein about 2 feet thick in brecciated argillite and graywacke; the mineralized breccia zone is nearly parallel to the bedding. The quartz carries inclusions of the country rock and generally sparsely disseminated pyrite, chalcopyrite, and a little galena and sphalerite. Part of the vein is a solid mass as much as 13 inches thick of galena and minor tetrahedrite.Lead-isotope studies of galena from the Silver Bell occurrence (Maas and others, 1995, p. 229-248) indicate that the deposit is Eocene in age, contemporaneous with emplacement of the Hyder Quartz Monzonite.

Additional commentsProspect originally staked in 1925. Vein was exposed for a length of 50 feet at the time of Buddington's visit in 1929 (p. 97).
