Location and accuracy The Fireweed prospect is at the northwest end of Death Valley near the head of Granite Creek. it is about 1.2 miles east of hill 1284 and about 0.3 mile west of the center of section 13, T. 3 S., R. 19 W. The location is accurate.

Geologic setting

Geologic description

The Fireweed prospect was discovered in 2007 by a joint effort of Triex Minerals Corp. (2007) and Full Metal Minerals during a regional program of uranium exploration. The program was based on an airborne geophysical survey that identified several strong radiometric anomalies and an exploration model based on other uranium deposits in the area. The Fireweed area was covered by a grid of soil samples, ground geophysical surveys, sampling of rocks at the surface, and 5 short diamond-drill holes totaling 267 meters in 2007.
The prospect is on the eastern flank of a coarse-grained Cretaceous quartz syenite stock. But at the prospect itself, the rock is largely weathered outcrops of green feldspar porphyry and aplite. Twenty-one rock samples collected from three areas along nearly 2 kms of the prospect contained 0.14 to 0.82 percent U3O8. More than 300 pebbles of silica-hematite rock that were collected over an area about 1,800 meters long by 700 meters wide, had an average scintillometer reading of 4,500 counts per second and 34 had values above 15,000 counts per second. The five drill holes were mostly in quartz syenite; one cut hematite-silica zones similar in mineralogy to the pebbles collected at the surface.
Geologic map unit (-162.488931920596, 65.2276998859435)
Mineral deposit model Uraniferous, hematite-quartz zones in syenite.
Age of mineralization Probably Cretaceous or Tertiary based on the age of the host rocks and similarities to other uranium deposits in the area.
Alteration of deposit The mineralization is associated with zones of hematite and quartz.
