Comments on the location information

  • DEPOSITS ON SLOPES OF THE WHITE RIVER VALLEY, COVERING ABOUT 16 SQUARE MI WHERE ALUNITE IS SPORADICALLY DISTRIBUTED. COVERS PARTS OF T. 19 N., R. 7 E. AND T. 20 N., R. 7-8 E.
  • Lat/long is in Pierce county. Both King and Pierce counties are listed in the locations table, indicating that the deposit crosses the Pierce/King county boundary. So the order of the counties was changed making Pierce first to resolve the lat/long - county disagreement.

General comments

Subject category Comment text
Deposit THE DEPOSIT CONSISTS OF DISCRETE BODIES WHICH ARE IRREGULARLY SHAPED AND WITHOUT DEFINITE CONTINUITY IN ANY DIRECTION. FOUR OF THESE HAVE BEEN PROSPECTED. THESE BODIES ARE ASSOCIATED WITH LARGER MASSES OF LOWER GRADE MATERIAL. ALL BODIES OCCUR JUST BENEATH THE THICK LAYERS OR MASSES OF SILICIFIED ROCK. SIZE IS OF LARGEST ALUNITE BODY. AREA IS COMPLICATED BY LANDSLIDES. SOME GEOLOGISTS BELIEVE THIS MAY REPRESENT THE TOP OF A PORPHYRY SYSTEM IN WHICH THERE MAY BE A PORPHYRY COPPER AT DEPTH
