• associated with structures or centers of strong hydrothermal alteration (ie. Globe Hill). D. Quartz is sometimes seen as vein or open space filling and often associated with fluorite. E. Sulphates are an indication of hydrothermal alteration and occur in open spaces in the rock. Celestite and Barite are the most common in the district. ViI. % Fe or Mn OXIDES A. iron and or manganese oxides often are associated with higher grade intervals. They also tend to occur along fractures or sheeted zones. VIII. STRUCTURE A. Indications of structures can be noted from the chips. Strongly oxidized intervals, intervals with anomalous amounts of clay, and intervals showing some type of shearing indicate the possibilities of structures and should be noted. B. The intensity of the fractures and any interpretations (ie. sheeted zone, fault) should be noted in the structure column and a graphic display that represents • the intensity in the graphics column. IX. MINERALIZATION A. The mineralization graphics column should be used to graphically represent the style and intensity of mineralization. The mineralization column should include a written description of the style of mineralization (ie. disseminated very fine grained pyrite, pyrite veinlets, etc.). \. FILES A. A copy of the completed log should be given to the project geologist and the original given [n Brenda \Volfe to be input into the data base. B. The chip trays should be kept available ttn[il the data is plotted in case the project geologist has any questions and then i[ should be stored with the other chip trays, currently in the Coblentz building. CORE DRILLING AND LOGGING Geologic logging of cure provides a variety of valuable information for both Exploration and Operat„~n. Due to the high cost of core it is imperative we extract the best • information possible front the material we have to work with. The cure provides cri[ical geologic, assay, ore type, geotechnical and metallurgical data for the project area.
