Online_Linkage: http://dx.doi.org/10.14509/29688 Description: Abstract: In 2016, geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) and University of Alaska Fairbanks carried out a two-part geologic mapping and geochemical sampling project in the Tok River area of the Tanacross A-5 and A-6 quadrangles (June 12-26 and July 8-26). This report provides results of stream-sediment sampling for trace-element geochemistry. An initial suite of sediment samples was collected from streams draining known gold occurrences, including the Stibnite Creek and Noah prospects, and numerous prospects in the White Gold area. These samples were split in half and the two splits were sieved to -200 mesh and -80 mesh, respectively. The splits were then both analyzed to determine which size fraction was best for identifying gold anomalies in this part of the Alaska Range. In most samples, the -200 mesh fraction showed higher gold levels, and hence, all additional samples we collected were analyzed at -200 mesh. In some -80 mesh samples, gold and tungsten appear to show "nugget" effects not seen in the -200 mesh samples. The other trace elements are largely equivalent between the two mesh sizes. The second suite of samples was collected throughout the map area from streams draining color anomalies, from areas where DGGS mapping identified igneous rocks upstream, and from areas with suspected potential for base-metal or gold mineralization. Highlights of the analytical results include two samples draining the Noah prospect with greater than 1 part per million gold. The analytical data tables associated with this report are available in digital format as comma-separated value (CSV) files. Purpose: The combination of insufficient detailed geologic mapping, historical and current industry interest in the adjacent mineralized areas, and the recently published geophysical data prompted the DGGS Mineral Resources section to conduct a stream-sediment sampling program in conjunction with geologic mapping in the Tok River area.

Sample numbers were recorded in the field on sample bags and on field note sheets. The sample location tables were plotted in GIS software to visually verify location accuracy and cross checked for consistency against the sample numbers recorded on the bags. Samples were analyzed for a variety of major and trace elements by ALS Geochemistry using the methods listed below. In addition to ALS Geochemistry's accredited (ISO/IEC 17025-2005) internal quality-control program, DGGS monitored analysis quality with two standard reference materials, a gold standard and a base-metal standard. One of each standard was inserted into each batch of 20 samples submitted to ALS Geochemistry. Lab results were examined by the DGGS geologists to ensure that they are reasonable given the geologic context of the sample. Inconsistencies between the field data and the lab sample numbers listed on the COA (certificate of assay) are noted in the data tables. Logical_Consistency_Report: not applicable Completeness_Report: This data release is complete. The data tables have been lightly edited for clarity, but are generally provided as received from the lab. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Locations were recorded using handheld, WAAS-enabled GPS devices. WAAS-enabled GPS devices have a reported error of about 1 m (NSTB/WAAS T&E Team, 2006). Depending on degradation of the WAAS and GPS signals, the horizontal position error of sample locations in this report is in the range of 1-10 m.

In the field, sample locations were selected that were upstream of alluvial fans and as close to stream confluences as possible, while also accounting for availability of sample material and proximity to helicopter landing zones. Specific sites at the sample location were selected based on the presence of fine-grained sand and silt, and included eddies or plunge-pools behind boulders or logs, eddies along edges of streams, overbank deposits, and channel bars. Samples were collected with a shovel, screened by hand using a Garrett's Combination Sifter with a 0.483-inch square-hole mesh, and then further screened using a 0.0742-inch square-hole mesh (-10 mesh). Undersized material was collected in a 3-gallon plastic bucket and then all materials, fines, and water were poured into polypropylene sample bags (10 inch x 17 inch) specifically designed to capture fines and allow water drainage. Where possible, the sample bags were filled to capacity to provide enough sample material to split and sieve using both -80 mesh and -200 mesh screens. For the remaining samples, sample bags were filled to approximately 60 percent of capacity. Individual sample weights were measured after drying and are provided in the analytical results.

The samples were logged and dried at a maximum temperature of 60 degrees Celsius. An initial batch of 23 samples were each split with a riffle splitter, and sample splits were dry-sieved to less than 180 microns (-80 mesh) and to less than 75 microns (-200 mesh), respectively. The remaining 44 samples were dry-sieved to less than 75 microns (-200 mesh). Process_Date: 2016 Process_Step: Process_Description: Major- and trace-element compositions - Trace-element compositions for sediment samples were determined by ALS Geochemistry method ME-MS61: Four-acid digestion followed by inductively coupled plasma-atomic emission spectrometry (ICP-AES) and inductively coupled plasma-mass spectroscopy (ICP-MS). Platinum, palladium, and gold values were analyzed by 30 g fire assay with ICP-MS finish (ALS Geochemistry method PGM-MS23). Samples that exceeded detection limits for gold were reanalyzed by 30 g fire assay with atomic absorption (AA) finish (ALS Geochemistry method Au-AA25). Process_Date: 2016 Process_Step: Process_Description: Sample archival - Samples collected during this project, as well as laboratory sample rejects and pulps, will be stored at DGGS for the duration of the project and will be available for public viewing upon request. Once the project concludes, the samples and pulps will be stored at the Alaska Geologic Materials Center in Anchorage.
