Mineral-resources personnel from the Alaska Division of Geological & Geophysical Surveys conducted reconnaissance sampling of the William Henry Bay area in the Juneau C-4 and D-4 quadrangles, August 9-13, 2011. This sampling project was part of a statewide assessment of Alaska's potential for rare-earth element mineralization. During the William Henry Bay field project 46 rock, sediment, and heavy-mineral concentrate samples were collected for geochemical analysis (geochemical, major oxide, minor oxide, trace element, and rare earth elements). Fieldwork was performed to evaluate the mineral-resource potential of a block of State land near the mouth of William Henry Creek, and to investigate reported rare-earth-element, uranium, and thorium mineral occurrences on adjacent Tongass National Forest land. This fieldwork and sampling was conducted as part of the State's Rare Earth Element and Strategic Minerals Assessment project, which is designed to evaluate Alaska's potential for these resources. This project is part of the State's Rare Earth Elements and Strategic Minerals Assessment CIP funded by the Alaska State Legislature and managed by the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys. completed Alaska Division of Geological & Geophysical Surveys GIS Manager (907)451-5020 3354 College Road Fairbanks AK 99709-3707 USA dggsgis@alaska.gov 8 am to 4:30 pm, Monday through Friday, except State holidays pointOfContact notPlanned Critical Minerals Geochemistry Gold Major Oxides Minor Oxides Rare Earth Elements Strategic Minerals Strategic and Critical Minerals Assessment Project Trace Elements theme Alaska Division of Geological & Geophysical Surveys Alaska, State of Endicott River Juneau Mining District Juneau Quadrangle Lance Point Lynn Canal William Henry Bay William Henry Creek place Alaska Division of Geological & Geophysical Surveys The State of Alaska makes no expressed or implied warranties (including warranties for merchantability and fitness) with respect to the character, functions, or capabilities of the electronic data or products or their appropriateness for any user's purposes.

These elements, referred to as "layers," group and describe files that have intrinsic logical or topological relationships and correspond to subdirectories within the data distribution package. The metadata layer provides an FGDC metadata file and may include other documentation files. Attribute information for each data layer is described in this metadata file under the "Entity_and_Attribute_Information" section.

Rock samples were chosen and collected on the basis of potential for mineralization (as identified by visual inspection). Igneous rocks as well as rocks that exhibited veining or alteration were preferentially chosen for geochemical examination. Heavy mineral concentrates were isolated by hand-panning in the field. 2011-01-01T00:00:00 Sample preparation - All sample preparation for analysis was performed by Actlabs. Rocks intended for whole-rock analysis by Actlabs and those with a weathering rind were trimmed at DGGS with a tile saw prior to sample preparation at the laboratory. Rock samples were crushed to minus-10 mesh (1.7mm), mechanically split by riffling, and then pulverized to 95% minus-150 mesh (105 microns). A mild steel mill was used for pulverizing to minimize contamination of samples. Stream sediment and pan concentrate samples were dried at a temperature of 60C and then sieved to minus 80 mesh (177 microns). For Code-8 REE analysis, both rock and sediment samples were further pulverized to minus-200 mesh (0.074mm) using a mild-steel mill. Cleaning sand was used after every sample preparation to prevent contamination. 2011-01-01T00:00:00 Sample analysis - All samples were analyzed for major oxides, minor oxides and petrologic trace elements, as well as ore-related trace elements and rare earth elements. In addition to the internal quality-control program at Actlabs, DGGS monitored analysis quality by inserting igneous-rock and REE standards of known composition into the sample roster for every sample batch. The major oxide, minor oxide, petrographic trace-element, and ore-related trace-element analyses were conducted using inductively-coupled plasma - optical emission spectrometry (ICP - OES) and inductively-coupled plasma mass spectrometry (ICP-MS) following lithium metaborate/tetraborate fusion. Mass balance was used for the major-oxide and minor-oxide analyses as an additional quality control technique, requiring elemental totals of oxides to be between 98 and 101 percent. Gold assays were performed using gravimetric analysis following fire assay (FA-GRAV) on 29.16 grams of material. Separate splits of 4 samples were reanalyzed for gold using Instrumental Neutron Activation Analysis following fire assay (FA-INAA); grams of material analyzed is noted in the .csv file. 2011-01-01T00:00:00 Documentation revisions - We identified and corrected typographical errors in the description fields and in the file metadata. Data table headers were slightly modified to provide consistency with similar geochemical data releases. 2014-01-01T00:00:00 otherRestrictions Metadata Use Constraints: If the user has modified the data in any way they are obligated to describe the types of modifications they have performed in the supporting metadata file.
