This helicopter-supported sampling project was part of a statewide assessment of Alaska's potential for rare-earth element (REE) mineralization, and was funded by the Rare Earth Elements and Strategic Minerals Assessment capital improvement project. During this field project, 32 stream sediment and 28 heavy-mineral pan concentrate samples were collected for geochemical analysis (geochemical trace elements and rare earth elements). An additional historic U.S. Bureau of Mines sample from the area was also analyzed as part of this report. Highlights of the DGGS sampling project include documenting new gold-bearing drainages and identifying several samples with high REE values. Purpose: Fieldwork was performed to evaluate the mineral-resource potential of portions of the Tanana and Melozitna quadrangles. This 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.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: All geochemical trace-element and rare-earth-element analyses were conducted by ALS Minerals. Analytical methods and detection limits are listed in attribute definitions. In addition to the internal quality-control program at ALS Minerals, DGGS monitored analysis quality by inserting geochemical standards of known composition into the sample roster for every sample batch. DGGS staff plotted sample points and visually inspected locations to identify possible transcription errors Logical_Consistency_Report: not applicable Completeness_Report: This dataset contains all of the analysis for trace-element and rare-earth-element geochemistry complete at the time of publication for all samples collected in the Melozitna and Tanana quadrangles during July and August 2011. A few sample "twins" were excluded from analysis by the lab due to insufficient material. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data were downloaded from Garmin eTrex Legend HCx GPS units into a Microsoft 2007 Access database. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 3 Horizontal_Positional_Accuracy_Explanation: A value of estimated position error in meters was calculated by Garmin eTrex Legend HCx GPS units and recorded for each sample location. Estimated position error calculated by Garmin eTrex Legend HCx units had a minimum of 1 meter, a maximum of 9 meters, and an average of approximately 3 meters. The GPS system suffers from calculation and geometric error such as error in satellite positions, mathematical error introduced by the GPS formulas used to calculate position, and errors caused by narrow satellite alignments. Estimated position error is a value determined by the GPS manufacturer for the calculation and geometric error as a whole. 'Selective availability,' a deliberate degradation of GPS data managed by the U.S. government, was not operating during the time period these samples were collected. Lineage: Process_Step: Process_Description: Fieldwork - For the DGGS study, major and minor watersheds (stream drainage basins) were selected for sampling prior to field work based on geographic criteria and stream-sediment geochemical anomalies in National Uranium Resource Evaluation (NURE) data. In the field, specific sample sites were selected by visual inspection from the helicopter, and were based on the availability of sample media and a suitable landing zone. Sites along streams/rivers were then selected, in order of preference from highest to lowest, as follows: gravel/cobble-armored riffles, gravel/cobble-armored point bars, log/boulder/plunge-pool eddies, point bars, overbank flood deposits, and moss mats. Where practical, sediment was collected over a 50-meter-long stretch of watercourse and combined into a composite sample. Stream-sediment samples were collected with a shovel. Cobbles and larger pebbles were manually screened out by hand, and the remaining material was placed into a permeable cloth sample bag. In order to obtain a sufficient volume of fine sediment, 7-inch-wide by 12-inch-long sample bags were filled to capacity. For pan-concentrate samples, sediment was collected with a shovel and then screened using a "Garrett's Combination Sifter" with a 0.483-inch, square-hole mesh. The resulting under-size material was collected in a 14-inch-diameter "Garrett's Gold Trap" gold pan. Sediments were screened until the gold pan was level-full with -0.483-inch material. Using alternating shaking and washing motions, the sediment was reduced to visible heavy minerals or a volume of approximately 30 ml. This concentrate was then washed into Nasco Whirl-pak plastic sample bags. Process_Date: 201204 Process_Step: Process_Description: Sample Prep - Pan-concentrate samples were dried at DGGS using a hot plate and glass petri dishes, which were washed after each use to prevent cross-contamination. Dried samples were split manually into two, equal-size, homogeneous portions using a razor, which was washed after each use. Samples were submitted to ALS Minerals (formerly ALS Chemex), where the sediment and pan-concentrate samples were logged, air-dried at low temperature, and weighed. The samples were then sieved to a particle size of -180 microns (80 mesh). Both fractions were retained, and the -80-mesh fraction was used for analysis. Process_Date: 201109 Process_Step: Process_Description: Sample Analysis - All samples were analyzed for ore-related trace elements and the full suite of rare earth elements. In addition to the internal quality-control program at ALS Minerals, DGGS monitored analysis quality by inserting igneous-rock and ore-geochemical-pulp standards with known compositions into the sample roster for every sample batch. Trace-element compositions were determined using inductively coupled plasma, atomic emission spectroscopy (ICP-AES) following a four-acid digestion process. Rare-earth- and additional trace-element compositions were determined using inductively coupled plasma, mass spectroscopy (ICP-MS). ICP-MS samples were dissolved in acid following lithium borate fusion. Platinum, palladium, and gold values were obtained from a 30-gram sample using inductively coupled plasma - atomic emission spectroscopy (ICP-AES) following fire assay. Sample 11RM23232P was outside the range for gold for this method, and was re-analyzed using gravimetry. Detection limits for each of the reported elemental values obtained by the various methods are documented in the metadata file.
