Import Drillholes from MX Deposit

Summary

Imports subsurface drillhole or borehole data from MX Deposit into a feature dataset in a geodatabase.

Usage

The imported drillhole data will be stored in a feature dataset (called "Drillholes"), with feature classes created for each data type that is associated with the imported drillholes:

Collars (point features, surface location of each drillhole)
Traces (polylines, created from collar and survey data)
Interval data sets ("from-to" data line segments of varying lengths along the drillhole trace, with attributes)
Point data sets (point features that are located along the drillhole trace, with attributes)

When importing data from MX Deposit, the imported symbology can be applied to any drillhole attribute or feature layer.

A Refresh option can be used to quickly update the imported drillholes with the latest up-to-date data from the MX Deposit database.

Parameters

Parameter	Explanation	Data Type
Output Drillhole Dataset	The name of the geodatabase feature dataset in which to store the imported drillhole data.
MX Deposit Project	The list of projects currently available in the MX Deposit database. Projects are site-specific, exploration (drilling or surface sampling) data collection programs. You will only see the projects that you have been given access to in MX Deposit.
Activity	The list of activities associated with the selected MX Deposit project. Activities are data capture workflows that require data to be entered in a specific way (e.g. exploration drilling vs. grade control). You will only see activities that you have been given access to in MX Deposit. Drillholes that are "New" or "In Progress" are excluded from the Activity list.
Coordinate system	The coordinate system to be used to spatially reference the imported drillhole data. Defaults to the top ranked coordinate system in the MX Deposit project tables. Only non-Geographic coordinates are supported in drillhole project databases.

Technical Notes

About MX Deposit

MX Deposit is a cloud-based logging application designed to help mining and exploration companies simplify and modernize how drilling and geological sample data is collected, managed, and shared. MX Deposit drillhole data can be logged and accessed from anywhere in the world. The MX Deposit application has been initially integrated with the Geosoft applications, Target and Target for ArcGIS and enabled explorers to easily import drillhole projects from MX Deposit directly into the Geosoft environment and to provide easy interaction between the MX Deposit source database and the imported drillholes. The integration with Target Pro enables the import of drillhole projects from MX Deposit directly into the ArcGIS Pro environment.

A subscription is required in order to access and import drillhole data from the MX Deposit data management portal. To learn more about subscriptions options, go to http://www.geosoft.com/products/mxdeposit.

Desurveying Drillholes using Collar and Survey data

The drillholes are always "desurveyed" on import, which means a 3D spatial object (a drillhole "trace") is calculated for each drillhole. The output trace for any given hole can vary depending on what type of data is available during import (collars only, vs. collar and survey data) and which method is selected to do the desurvey calculations, as well as the resolution value selected. The various ways to calculate the traces, depending on which types of data are available, are described below:

With collar locations only, no survey data present:

If collar data includes dip and azimuth, these values are used to create straight segment traces for the entire hole, to the final depth.
If collar data does not include dip and azimuth, the holes are assumed to be vertical.

With collar locations and dip-azimuth survey data:

The survey data is "discretized" at the desurvey resolution interval value and a smooth curve is generated using the selected desurveying method (the default is the "Radius of curvature" method). See Drillhole Settings for more details.
Holes are 'desurveyed' and the new trace geometries are stored in the Traces, Depth Ticks, From/To and Point datasets.
The top-of-hole dip and azimuth values (at depth = 0) will use the values from the Survey feature class, if present.
If top-of-hole survey values are not present, the collar dip and azimuth values will be used instead (with the collar values taking precedence).
