Relative position | The Dalcoath dike prospect is about 1 mile north of the Lost River Mine (TE048-TE051). It is on the south side of the ridge separating Crystal Creek and the headwaters of Cassiterite Creek, both east tributaries to Lost River in the York Mountains. The surface trace of the dike, which trends N 50 E and dips about 65 degrees north, has been mapped by Sainsbury (1969, plate 1) at elevations of 600 to over 1,000 feet. This location was not identified separately by Cobb and Sainsbury (1972) or Cobb (1975). |
