method at takigami area in Japan," in Proceedings of the 13th Workshop on Geothermal Reservoir Engineering Stanford University, SGP-TR-176, Stanford, Calif, USA, January 2005.
The company used the results of the previous gravity survey to place the CSAMT
survey lines over two deep zones in the central portions of the Clayton Deep basin.
is a deep-looking geophysical technique that measures lateral and vertical resistivity contrasts which are important for evaluating the presence of geologic units which are favourable to host large tonnage gold deposits similar to those found elsewhere in Nevada.
The extension applications were made to encompass MMAJ-defined areas of hydrothermal alteration co-incident with gravity high, CSAMT
geophysical and geochemical soil anomalies, some 2 to 3 kilometres southeast of the historic Matsuno mine workings.
has proceeded with the systematic quantification of the MI's mineral potential including airborne geophysical, gravity, UTEM, CSAMT
, remote sensing, geological, petrographical and geochemical surveys.
As a result high-resolution seismic reflection and controlled-source, audio-frequency magnetotelluric (CSAMT
) experiments were carried out during the summer and fall of 1989.
These include a twelve-line controlled source audio-magnetotellurics ('CSAMT
') and audio-magnetotellurics ('AMT') survey to look for structures and silicified rocks and a detailed gravity survey to help identify significant cross structures that might host vein mineralization but were not necessarily tested by phase one drill holes,.
A Controlled Source Audiomagnetotellurics (CSAMT
) survey and a natural source Magnetotelluric (MT) survey have identified the continuation of the favorable Getchell Trend structures onto the Snowstorm property and into the sedimentary package.
The second stage of geophysical exploration includes scalar CSAMT
surveys (Controlled-Source Audio-Frequency Magneto-Telluric) to map geologic stratigraphy and structure, relative to the occurrence of lithium brine, identify conductors that are thought to be representative of lithium bearing brine, and to provide information for the selection and design of additional geophysical surveys.
The second stage of the 2019 exploration program consists of a caldera-wide geophysical survey utilizing the Controlled Source Audio-frequency Magnetotellurics (CSAMT
) method, capable of obtaining high resolution subsurface 3D map imagery to depths of 1,000m below surface.
