Wyatt, W.C. 2018 report and digital data Raw Data File RDF 2018-6 Fairbanks, Alaska, United States Alaska Division of Geological & Geophysical Surveys 4 p. http://doi.org/10.14509/30119 During the 2018 field season, geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted geologic mapping and sampling of part of the Richardson mining district southeast of Fairbanks, including parts of the Big Delta B-5 and B-6 quadrangles. The project area has produced approximately 122,000 ounces of gold (Singh and others, 2017), mostly from placer mines, and it includes the Richardson, Tower, and Hilltop lode gold exploration properties. Rock outcrop accounts for much less than one percent of the study area, consequently, many of the rock samples were collected from up to 1-meter-deep pits dug with shovels into rocky colluvial deposits below the surficial loess. Highlights of the geochemical results include 43.3 and 9.77 parts per million (ppm) gold sampled from arsenopyrite-bearing quartz veins at the Hilltop prospect. At the Democrat prospect, formerly the site of small-scale mining, a sample of sulfide-rich material returned 3,790 ppm silver and 4.72 ppm gold. Other samples from the Democrat prospect assayed 6.81 and 5.01 ppm gold. The analytical data tables associated with this report are available in digital format as comma-separated value (CSV) files. All files can be downloaded from the DGGS website (http://doi.org/10.14509/30119). The Richardson project area has produced approximately 122,000 ounces of gold (Singh and others, 2017), mostly from placer mines, and it includes the Richardson, Tower, and Hilltop lode gold exploration properties. The goal of DGGS's work in this area is to conduct a mineral-resource assessment and to build an improved understanding of the area's geology and controls on gold mineralization to facilitate industry exploration targeting. >major-oxide-trace-element: Major- and minor-oxide and trace-element analysis of rock samples; includes magnetic susceptibility measurements >trace-element: Trace-element analysis of rock samples; includes magnetic susceptibility measurements 2018 ground condition complete None planned -146.716284 -146.005636 64.533013 64.248344 ISO 19115 Topic Category geoscientificInformation Alaska Division of Geological & Geophysical Surveys Analyses Analyses and Sampling Analytical Lab Results Analytical Results Base Metals Chemistry Economic Geology Exploration Geochemical Data Geochemical Surveys Geochemistry Geologic Geology Lab Methods Major Oxides Metals Methods Mineral Assessment Mineral Deposit Mineral Localities Mineral Prospect Mineral Resources Minerals Mining Minor Oxides Non-Metals Ore Deposit Ores Precious Metals Prospecting Sites Resource Assessment Resource Information Resources Sample Location Trace Elements Trace Geochemical Trace Metals Alaska Division of Geological & Geophysical Surveys Banner Creek Big Delta Quadrangle Buckeye Creek Canyon Creek Delta Creek Democrat Creek Junction Creek Mosquito Creek Richardson Mining District Shamrock Creek Shaw Creek Shaw Pond Tenderfoot Creek This report, map, and/or dataset is available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

In addition to ALS Geochemistry' accredited (ISO/IEC 17025-2005) internal quality-control program, DGGS monitored analysis quality with at least one standard reference material per batch of 20 analyses. not applicable This data release is complete. Location data were collected using GPS-enabled tablets (2017 Samsung Galaxy Tab A) running the ESRI Collector App. The devices have a reported error of about 10 m. Latitude and longitude are reported in the WGS84 datum. Field data collection - During the 2018 field season, geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted geologic mapping and sampling of part of the Richardson mining district southeast of Fairbanks, including parts of the Big Delta B-5 and B-6 quadrangles. 2018 Sample selection - Rock samples were collected for two different purposes. First, samples of visibly mineralized or altered rock were preferentially collected and analyzed for trace-element geochemistry. Second, igneous and metaigneous rocks showing little alteration or weathering were collected for whole-rock major-oxide, minor-oxide, and trace-element analyses to aid in classification and study of petrogenesis and tectonic setting. Most samples are grab samples, which were collected for their overall representation of the outcrop. However, a few samples are select samples, which were more deliberately collected from a specific feature, as noted in the sample field description. Rock outcrop accounts for much less than one percent of the study area, consequently, many of the rock samples were collected from up to 1-meter-deep pits dug with shovels into rocky colluvial deposits below the surficial loess. 2018 Magnetic susceptibility measurements - Magnetic susceptibility measurements were collected using Terraplus KT 5, 6, 9, and 10 model handheld magnetic susceptibility meters. The values reported here are for individual measurements performed on representative surfaces of the sampled rock outcrop. 2018 Sample preparation - Rock samples were processed by ALS Geochemistry using their PREP-31 package. The samples were crushed to greater than 70 percent passing 2 mm, and a 250 g split was pulverized to greater than 85 percent passing 75 microns. Prior to crushing, samples for whole-rock analysis were trimmed by DGGS staff to remove weathering, and cut surfaces were sanded to remove any saw metal. 2018 Major- and trace-element values for rock 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); Au values were analyzed using flux digestion and fire assay and ICP-AES (ALS Geochemistry method Au-ICP21); Hg values were analyzed by aqua regia digestion followed by ICP-MS (ALS Geochemistry method Hg-MS42). 2018 For whole-rock geochemistry samples, major and minor oxides were analyzed by lithium metaborate fusion digestion and ICP-AES (ALS Geochemistry method ME-ICP06). Trace elements, including rare-earth elements, were determined using lithium metaborate fusion digestion and ICP-MS (ALS Geochemistry method ME-MS81). Ag, Cd, Co, Cu, Li, Mo, Ni, Pb, Sc, and Zn were determined by four-acid digestion and ICP-AES (ALS Geochemistry method ME-4ACD81); and As, Bi, Hg, In, Re, Sb, Se, Te, and Tl were determined by aqua regia digestion followed by ICP-MS (ALS Geochemistry method ME-MS42). Total C and S were analyzed by Leco furnace (ALS Geochemistry methods C-IR07 and S-IR08, respectively). Au was analyzed using flux digestion and fire assay and ICP-AES (ALS Geochemistry method Au-ICP21). 2018 Samples that exceeded detection limits for elements of interest were reanalyzed using specific elemental tests. Over-limit values for Au were analyzed using 30-g fire assay with gravimetric finish (ALS Geochemistry method Au-GRA21). Overlimit values for Ag were analyzed by four-acid digestion followed by inductively-coupled plasma-atomic emission spectrometry (ALS Geochemistry method Ag-OG62) or by 30-g fire assay with gravimetric finish (ALS Geochemistry method Ag-GRA21). Overlimit values for Pb were analyzed by four-acid digestion followed by inductively-coupled plasma-atomic emission spectrometry (ALS Geochemistry method Pb-OG62). 2018 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. 2018 point 0.000001 0.000001 decimal degrees World Geodetic System of 1984 WGS 84 6378137 298.257223563000025 rdf2018-6-major-oxide-trace-element.csv, rdf2018-6-major-oxide-trace-element-limits.csv Major- and minor-oxide and trace-element analysis of rock samples; includes magnetic susceptibility measurements.
