General comments

Subject category Comment text
Deposit ALL WORKINGS ARE CONFINED TO AN APPARENTLY UP-FAULTED BLOCK OF HIGHLY SILICIFIED AND FE-STAINED LIMESTONE. THERE IS A SERIES OF APPROXIMATELY 6 SILICIFIED LIMESTONE KNOBS WHICH FORM A RIDGE AND FLAT AREA OUT FROM THE MAIN MOUNTAIN FRONT. THE LIMESTONE IS HIGHLY FRACTURED AND SILICIFIED. NUMEROUS QUARTZ VEINLETS AND CONSIDERABLE FE OXIDE PRESENT. FE-GOSSAN IS DEVELOPED IN A FEW PLACES. SOUTHERN PACIFIC CO. REPORTED THIS AREA AS "ALTERATION ZONE ASSOCIATED WITH SHEAR AND FAULT ZONES IN RHYOLITE INTRUSIVE BRECCIA", SHOWING LITTLE PROMISE, (1964).

Operator history (post-MRDS)

MRDS records operators as of each record's last update (≤ 2019). Some of the operators listed here have since changed hands or dissolved:

  • Atlas Minerals Corp. — dissolved ~1998
    Atlas Corporation filed Chapter 11 in 1998 amid uranium-mine reclamation liabilities. Mining assets were dispersed in bankruptcy.
