The fieldwork provides basic information critical to building an understanding of Alaska's geology and is part of an integrated program of airborne geophysical surveys followed by geological mapping. During 2009, 57 rock samples were collected for geochemical trace-element analysis, 107 rock samples were collected for whole rock (major- and minor-oxide and petrogenetically important trace elements) analyses, and 2 samples were collected for analysis of non-carbonate carbon content. Additionally, 288 polished rock slabs were analyzed for whole rock and petrogenetically important trace elements. This report also contains geochemical trace-element analyses from the Mount Hayes A-2 Quadrangle, Alaska, for 359 rock samples collected by International Tower Hill Mines Ltd. (ITH) from July 2005 through August 2008 as part of the Chisna Project. These data were kindly donated to DGGS in 2009 to aid DGGS investigations. Purpose: The analyses in this report were acquired as part of a geologic mapping program, the purpose of which is to provide 1:50,000-scale geologic mapping of a portion of the Slate Creek-Slana River airborne geophysical surveys released by DGGS in 2009 (Burns et al., 2009). The geophysical survey (helicopter-based aeromagnetic and electromagnetic data) and geologic mapping are part of the Alaska Airborne Geophysical/Geological Mineral Inventory Program, a special multi-year investment by the State of Alaska to expand Alaska's geologic and mineral resources knowledge base, catalyze future private-sector mineral exploration and development, and guide state resource development planning.

Analytical methods and detection limits are located in the “Entity_and_Attribute_Information” section for tables 3, 6, 7, 9, and 12. This information is also described in the report text and the tables mentioned above. Aside from ALS Chemex’s own internal quality control program, DGGS monitored analysis quality by inserting a sample of known composition into the sample roster for every batch of 20 samples. The analytical results were statistically compared to similar standard compositions for the past ~10 years. ITH also monitored analysis quality by inserting samples of known composition into the sample roster, but the frequency of their checks is unknown. Analyses performed at UAF were standardized using well-characterized natural fine-grained rock and pure mineral standards as well as conventional pressed pellets of international rock standards. Logical_Consistency_Report: No topologic relationships are present in data. Completeness_Report: This dataset contains all of the analyses for trace-element geochemistry, whole rock (major- and minor-oxide, and trace element) geochemistry, and non-carbonate-carbon analyses for rock samples collected by DGGS in the Slate Creek project area in 2009. This dataset also contains Slate Creek area trace-element geochemical data collected by ITH, which is a subset of the data collected for the Chisna Project from 2005-2009. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data collected by DGGS were downloaded from Garmin 12XL GPS units into an Access database. ITH location data were recorded by PDAs with an integrated GPS unit. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 6 Horizontal_Positional_Accuracy_Explanation: A value of estimated position error in meters was calculated by Garmin 12XL GPS units and recorded for each sample location. Estimated position error calculated by Garmin 12XL units was not better than 3 meters and averaged approximately 6 meters. The GPS system suffers from calculation and geometric error. This error results from items such as error in satellite positions, mathematical error introduced by the formulas used by the GPS unit for calculating 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. Average position error of ITH’s GPS data is unknown but presumed to be of recreational GPS grade and similar in accuracy to the Garmin 12XL. '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 - Rock samples of visibly mineralized rock, or rock exhibiting features associated with mineralization, were collected and analyzed for geochemical trace elements. Spatially these rocks were collected randomly. Occasionally rocks exhibiting a specifc feature were selectively collected and these instances were noted in the sample description. Process_Date: 200907 Process_Step: Process_Description: Fieldwork - Rock samples collected for whole-rock (major oxides, minor oxides, and trace elements) analysis include samples representative of a typical lithology, igneous or possible meta-igneous samples in order to determine composition, and samples whose petrogenetically important trace-elements could indicate their original tectonic setting. Unweathered or minimally weathered rock samples were preferentially selected for analysis. Spatially these rocks were collected randomly. Process_Date: 200907 Process_Step: Process_Description: Fieldwork - Rock samples of visibly carbonaceous or graphitic rock were collected and analyzed for non-carbonate carbon content. Spatially these rocks were collected randomly. Unweathered or minimally weathered rock samples were preferentially selected for analysis. Process_Date: 200907 Process_Step: Process_Description: Sample Preparation - All sample preparation was conducted at the ALS Chemex sample preparation facility in Fairbanks, Alaska, except for preparation of whole-rock samples for analysis at the University of Alaska Fairbanks. Rocks intended for whole-rock analysis by ALS Chemex and with a weathering rind were trimmed with a tile saw prior to sample preparation at the laboratory. Rock samples were crushed with a Terminator oscillating jaw crusher with chrome steel alloy plates so that at least 70 percent of the material passes through a -10 mesh (2 mm) screen. Representative aliquots of 250 grams each were taken using a stainless steel riffle splitter. These samples were then pulverized in a chrome steel ring mill so that 85 percent of the sample passed through a -200 mesh (75 micron) screen. Trace-element analyses, whole-rock oxide analyses, and gold analyses were performed using representative splits of each 250 gram pulp. Process_Date: 200912 Process_Step: Process_Description: Analysis, Tables 1-3 - All potentially mineralized samples were assayed for gold by inductively coupled plasma-atomic emission spectroscopy following a 30 gram (g) fire assay fusion (FA-ICP-AES). Platinum and palladium were assayed for selected samples by inductively coupled plasma-atomic emission spectroscopy following a 30 g fire assay fusion (FA-ICP-AES). Trace-element geochemical analyses were performed by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) methods after four-acid, near-total digestion. This method of digestion is possibly incomplete for some elements and may result in lower analytical results for these elements. The elements that may be affected by incomplete digestion, analytical methods, and lower and upper reporting limits are tabulated in Table 3. Rock samples with trace gold and/or copper values above the detection limit in the initial trace element geochemical analysis were reanalyzed for those metals by the following methods: gold, fire assay with a gravimetric finish using a 30 gram sub-sample; copper, inductively coupled plasma-atomic emission spectroscopy (ICP-AES) methods after four-acid, near-total digestion. Detection limits for the second set of analyses are listed in Table 3. Process_Date: 200912 Process_Step: Process_Description: Analysis, Tables 4-6 - Major- and minor-element oxides were determined at ALS Chemex by XRF following a lithium borate fusion. Trace-element values for Ba, Nb, Rb, Sr, Y, and Zr were determined by XRF on a pressed pellet. Analytical methods and detection limits are tabulated in Table 6. Process_Date: 200912 Process_Step: Process_Description: Analysis, Table 7 - Non-carbonate carbon analyses were performed by ALS Chemex. Non-carbonate carbon content was determined using a LECO furnace after a dilute acid digestion. The lower detection limit for non-carbonate carbon is 0.01 percent, and the upper detection limit is 50.00 percent. Process_Date: 200912 Process_Step: Process_Description: Analysis, Tables 8-9 - XRF spectroscopic analyses performed at UAF were standardized using well-characterized natural fine-grained rock and pure mineral standards as well as conventional pressed pellets of international rock standards. Because volatile components were not measured and rocks were of varying porosities, the analyses were normalized to 100 percent totals. In the vast majority of cases the original analyses yielded totals of approximately 95 to 102 weight percent. Comparison between these analyses and those produced on the same rocks by conventional pressed pellet (trace elements) and fused disk (major and minor oxides) techniques indicates that major- and minor-oxide and trace-element concentrations are most likely within 10 percent of the ‘true’ concentrations. Analytical methods and detection limits are tabulated in Table 9. Process_Date: 200912 Process_Step: Process_Description: Analysis, Tables 10-12 - All samples were analyzed for gold using a 50 g fire assay fusion and either ICP-AES or atomic absorption spectrometry (AAS). Trace-element geochemical analyses were performed by inductively coupled plasma-mass spectrometry (ICP-MS) methods after four-acid, near-total digestion. This method of digestion is possibly incomplete for some elements and may result in lower analytical results for these elements. Samples with greater than 10 percent calcium and showing interference were reanalyzed by ICP-AES, and these results are shown. Mercury was analyzed by aqua regia digestion/cold vapor-AAS (detection limits on samples requiring dilutions for mercury analysis were increased according to the dilution factor). The elements that may be affected by incomplete digestion, analytical methods, and lower and upper reporting limits are tabulated in Table 12. Rock samples with trace metal values above the detection limit in the initial trace element geochemical analysis were reanalyzed for those metals by the following methods: gold, fire assay with a gravimetric finish using a 50 gram sub-sample; silver and copper, ICP-AES methods after four-acid, near-total digestion; sulfur, total sulfur by Leco furnace. Detection limits for the second set of analyses are listed in Table 12.
