This digital publication, GPR 2014-3, contains CGG's analysis and interpretation of data produced from airborne geophysical surveys published by DGGS in 2013 (GPR 2013-1) for the Southern Dishna River, Fox Hills, and Beaver Creek survey areas. These three survey areas are informally referred to as the Five Spot survey in places in this publication. CGG's frequency-domain DIGHEM V system was used for the EM data. GPR 2014-3 includes (1) CGG's project report with interpretation and detailed EM Anomalies, and (2) Multi-channel stacked profiles in pdf format. Interpretation maps and EM anomalies are provided in various formats (e.g., Geotiffs, KMZs, and others) and are listed in detail in GPR2014-003 ReadMe (.txt and...

This digital publication, GPR 2013-1, contains data produced from airborne geophysical surveys conducted in 2012 for three separate blocks, the Southern Dishna River, Fox Hills, and Beaver Creek survey areas, in the Iditarod, Ophir, and Holy Cross quadrangles in western Alaska. The areas are in the Iditarod, Innoko, and Aniak mining districts. Aeromagnetic and electromagnetic (EM) data were acquired by helicopter for about 1029 sq miles. Fugro Airborne Survey's frequency-domain DIGHEM V system was used for the EM data. GPR 2013-1 includes (1) raw and processed linedata; (2) gridded, Google Earth, and Geotiff formats of the calculated linedata; (3) maps of the data; and (4) vector files of data contours and flight...

This digital publication, GPR 2014-4, contains CGG's analysis and interpretation of data produced from airborne geophysical surveys published by DGGS in 2013 (GPR 2013-1) and 2014 (GPR 2014-5) for the Middle Styx and Farewell survey areas respectively. The two survey blocks Farewell and Middle Styx are referred to as the 'Farewell' survey in the project report as these blocks were flown under one contract. Elsewhere the separate block names, Farewell and Middle Styx, are typically used. CGG's frequency-domain DIGHEM V system was used for the EM data. GPR 2014-4 includes (1) CGG's project report with interpretation and detailed EM Anomalies, and (2) Multi-channel stacked profiles in pdf format. Interpretation maps...

This digital publication, GPR 2014-1, contains data produced from airborne geophysical surveys conducted in 2013 for the Talkeetna Mountains, Healy, and Mt. Hayes quadrangles in south-central Alaska. The area is in the Valdez Creek and Delta River mining districts. Aeromagnetic and electromagnetic (EM) data were acquired by helicopter for about 1310 sq miles, and additional data donated by Millrock Exploration Corporation, Anchorage, increased coverage by about 12 sq miles. Millrock also provided some infill flight lines for over a similar amount of sq miles. CGG acquired and processed all the airborne geophysical data. The data were all flown with the same systems and contract specifications. CGG's frequency-domain...
