Geological survey will provide basic data relevant to all
fields of geosciences. For preparing high-quality data, it will be necessary
for the field geologists to possess the ability to read and interpret all
information available from a single outcrop, a single rock sample, or a
single geological map.
Our capabilities regarding field geology are based on 100-years experiences
of the Nippon Mining Holdings Group (Japan Energy Corp., Nippon Mining &
Metals Co., Ltd., Pan Pacific Copper Co., Ltd.), and we endeavor to flexibly
adapt to new developments in the various fields of sciences and engineering. |

| Major geological activities |
| ■Examination of all existing geoscientific
information |
| ■Surface geological survey (reconnaissance
verification survey, geological map preparation by detailed survey, survey
of fissure systems, alteration zone survey, survey of geothermal manifestations
and hot springs, magnetometer survey) |
| ■Mine survey (underground and field) |
| ■Ore reserve computation |
| ■Geochemical survey (rocks, soil, soil gas,
geothermal fluids, hot spring water, surface waters, groundwater) |
| ■Investigation of drill cores and cuttings
microscopic observation of thin sections, and polished sections |
| ■Laboratory tests & analysis (powder x-ray
diffraction, sections, and polished thin sections of rocks/ores, EPMA analysis,
chemical analyses of rocks/ores, age determination of rocks/ores) |
| ■Integrated analysis and interpretation of
the results of mineral exploration, geothermal
exploration, hot spring exploration, and other relevant surveys (extraction
of promising mineralized zones, selection a of hot spring drilling sites,
etc.) |
