Lynx Claim

The Lynx Claim is a tungsten and gold mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Mertie, 1918

Comment (Workings): Workings / Exploration = A 60-foot shaft and several short adits were driven during or before 1920; the deposit was discovered before 1903 (Collier and others, 1908).

Comment (Geology): Geologic Description = This deposit consists of sulfide- and scheelite-bearing quartz veins, layers, and lenses as much as 6 inches thick separated by sulfide-bearing schist. The quartz bodies are parallel to the foliation in the schist. The deposit was first reported by Collier and others (1908, p. 193) as a gold prospect. Selected samples contained as much as 0.5 ounce of gold per ton. The same locality was probably reported as the Lynx claim by Mertie (1918 [B 662-I, p. 457]). The deposit was developed by a 60-foot shaft. Scheelite, quartz, and sulfidized schist were run through a sluice box, and about 600 pounds of scheelite were recovered. A dredge working below the deposit recovered scheelite in placer gold concentrates. Cathcart (1922, p. 241) reported a 20-foot-long adit at about the same location. The adit exposed a 1-foot quartz-feldspar vein within highly sulfidized schist walls. Cathcart (1922, p. 234, 241-242) described other nearby deposits, including mineralized schist similar to Sophie Gulch (NM208), in a gully south of Glacier Creek immediately above Snow Gulch. At that location, a quartz-feldspar vein cuts contorted sulfidized schist. Anderson (1947) reported scheelite and stibnite in prospects in the Glacier Creek--Snow Gulch area.

Comment (Geology): Age = Mid-Cretaceous; veins cross cut regionally metamorphosed schist; see NM207.

Comment (Deposit): Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a).
