Trench Validation

Before using drillhole functions you should validate your trench data. If you do not validate your trench data, the drillhole functions will generate error messages whenever inconsistencies are found.

On the Drillhole tab, in the Validation group: Select Validate Trench, to open the Trench Validation form.

What Trench Validation checks for

Trench Assays and Events

File

Double-click (or click on the Select icon) to select the names of the Assay and Event data files containing your data. If required, define a filter to selectively control which records will be validated.

Select the file type for the Assay and Events files from the drop down.

Filter

You can select this check box and specify a filter to limit the data from the Assay or Event file that will be considered in the validation.

Trench fields

Specify the names of the fields that identify each trench in the Assay and Event files.

From and To fields

Specify the names of the From and To fields in the Assay file. The To value is always greater than the From value and the difference between them (To - From) is the length (or thickness) of the interval.

Trench Survey

Double-click (or click on the Select icon) to select the names of the Survey data file containing your data. If required, define a filter to selectively control which records will be validated.

Forms

Click the Forms button to select and open a saved form set, or if a form set has been loaded, save the current form set.

Run

Click Run and a series of status messages will appear as the Validation process validates the trench files. If an error is detected, an appropriate message will be displayed.

After the run is complete, correct any errors and re–run Validate. Continue this process until your trench data is error free.

Correcting one error may lead to the detection of another.
