|Location and accuracy||The Athero prospect is at Lance Point on Lynn Canal. It is in the W1/2 section 22, T. 36 S., R. 61 E. of the Copper River Meridian. The location is accurate within 1/2 mile.|
Geologic descriptionThe general area is underlain mainly by Silurian and Devonian graywacke and argillite and Middle Devonian carbonate, clastic and volcanic rocks (MacKevett and others, 1971; Brew and others, 1978). The host rocks at this prospect are Silurian graywacke and Devonian and Silurian greenstone intruded by small bodies of Cretaceous quartz monzonite and syenite (Clough and Redman, 1989). Eakins (1975) describes potential uranium-thorium mineralization and Wells and others (1986) report a lode claim at this site. The U.S. Bureau of Mines sampled a quartz vein but it did not contain any elevated metal values (Clough and Redman, 1989) Alaska Kardex file 112-109 shows a uranium claim at this site.
