Relative position | The Silver Star prospect is in Section 12 about 2.7 miles east-northeast of the outlet of Texas Lake. It consists of an upper zone at an elevation of about 3750 feet, and a lower zone at an elevation of about 3000 feet (Elliott and Koch, 1981, p. 14, loc. 47). The map coordinates are for the approximate midpoint between the zones and are probably accurate within about a quarter of a mile. |
