Geological Survey and Analysis

Geological Survey and Analysis 1 (Geological Services)

Geological Mapping and Data Processing
Recommended for:
  • - Geological mapping and DDH core logging in projects to obtain geological data.
  • - Preliminary analysis of existing literature, image analysis, and lineament deciphering, for field surveys.

Case 1)

A trading company:

“A report calculating the amount of ore resources is required for our investment partner.”

Ore type:
Nickel (laterite ore)
Our support:
We provided geological data analysis, and calculated the amount of ore resources. The deliverables were a report on the amount of ore resources and all related datasets.

Case 2)

A private company:

“Calculate the amount of ore resources for a project currently under review and determine if there are any problems.”

Ore types:
Cu-Au (porphyry)
Our support:
We provided geological data analysis, and calculated the amount of ore resources. The deliverable was a review of ore resources.
Our instruments and software for survey and analysis
GIS software ArcGIS, QGIS, Mapinfo Discovery, Oasis Montaj
Ore resources calculation MineSight from MINTEC, Inc.
Aerial photographs obtained by UAVs from DJI and original mag survey systems (under development)
Other data processing software --- Grafer, Surfer, Voxler, Strater from Golden Software, LLC.
--- Pix4dMapper from PIX4D SA.
--- UgCS (UAV auto running program) from SPH Engineering.

Geological Survey and Analysis 2 (Exploration and Mining)

Consulting Services
We provide the following services:
  • - Temporary staff for exploration projects and basic surveys of sand erosion barriers.
  • - Temporary staff at project sites.
  • - Geologists and/or mining engineers to visit your project site. We will support your project as your technical partner when buying or selling exploration/mining properties and when surveying the current status of your interested concession.
  • - Visiting your project site in your place to confirm progress.
    We support your project as follows.
  • - Being part of exploration projects and disaster prevention surveys (landslides, earth and rocks, steep slopes). Geotechnical engineers are also recommended for this.
  • - Acting independently as a field liaison in exploration projects.
  • - Finding a project you would like to consider, such as the acquisition of exploration and/or mining licenses, and accompanying you to the site for a field survey.
  • - Conducting site visits on our behalf or monitoring the progress of multiple existing exploration projects when you do not have time to do this.

We also provide services for projects that require interviews, surveys, and analysis on a case-by-case basis depending on the status of the project. Additionally, our services cover projects that require status updates and problem identification. We also offer consulting services for tasks that are difficult to provide specifications for ahead of time (requiring a fast response to a situation, rather than predetermined surveys and analysis).


Case 1)

A private company:

“Information regarding the Mining Act and the process of mining property acquisition in Japan are required.”

Our support:
A report that specifies the acts and processes for mining property acquisition, including related documents and pictures, was delivered.

Case 2)

A trading company:

“Identify the problems in an investment project currently under review.”

Our support:
We worked in their office and supported the review and analysis process there. The project was in an advanced stage and had a large amount of documents and data. They needed to understand the project in a limited time.

Geological Survey and Analysis 3 (Assays and Disaster Prevention Surveys)

Dating, Mineral Assays, Structural Analysis of Loose Rock, and Disaster Prevention Surveys

We conduct geochemical analysis and field surveys in collaboration with the HIRUZEN Institute for Geology & Chronology. K-Ar dating, mineral assay, reshaping loose rocks (fault, clay) from drill cores, and deformation structure analysis of drill cores are available.

Examples of delivery times and offered services
K-Ar dating 3 months
Mineral separation Approximately 1 month, depending on the mineral species
Mineral analysis Making thin sections, microscopy observations, XRD, XRF, EPMA, and other methods (please inquire).

Instrument Rental Services for Land Surveys/Basic Land Survey Services

We provide rental services for TOPCON’s GNSS systems and basic land survey services in your field.

  • - GCP is required for drone surveys.
  • - The coordinates of the drilling point are required. However, professional contractors only offer solutions that are expensive, time-consuming, and over-engineered.

We conduct a simple, fast and precise survey even if your manpower and time are limited.
The VRS RTK network is also available through our instrument rental services.

- Our instrument for land surveys is the Hyper-V GGDM-D from TOPCON.
- The FC-500 is used for data collection.
- Positional information is acquired under a contract with Jenova Co. Ltd., and the collector is available with presets.

  • - Please contact us about the rental price.
  • - We also provide post-processing services using GNSS-pro.
