SC. Block Model
- iarmstrong
In the Block Model step you will be prompted to load your block models. A reserve model is a collection of block models. Each project loads a single ".resmodel" file at a time.
Button | Description |
|---|---|
| Use New button to create new reserve model files |
Use Open button to load reserve model files | |
Use Edit button to open a window, where block models may be added or removed from the reserve model | |
Use Close button to delete the block model | |
Use Export button to export the selected block model in ".csv" format |
Create a Reserve Model
Press the New button to open the Reserve Model Generator.
Press blue plus button > select “CSV File” option > import “bm1.csv” file.
Set the green Header Line to match the header text.
Set the yellow Data Offset to match the first row of data.
Press OK to finish.
When the block model is loaded, its header fields are listed in the Variables panel on the right.
Drag and drop the variables to the appropriate field (or double click to map to the selected field).
Numeric fields use the N("field") syntax, and text fields use the T("field") syntax.
New reserve fields can be created by clicking the sum , weighted , and class icons in the top button ribbon. These add new rows into the field list.
Sum fields are summed together, such as volume, tonnes and gold ounces.
Weighted fields are weight-averaged by a sum field, such as iron percent or gold ppm.
Class fields create subtotals of a sum field, such as Indicated / Inferred / Measured.
The Parcel field is used to categorise the material type in each block model cell.
Most block models contain a material type field, such as "MatType" or "IDProduct'.
If there is no material type field in the block model, see the Block Model Formulas section to write your own.
Be careful to use the text T("material") syntax so that the parcel is read as text, not as a number.
If the Errors panel is blank, and once all fields are mapped, press Generate to build the reserve model.
A Conformetrics project needs a valid link to the reserve model file in order to calculate reserves.
As such, a good rule of thumb is to save the reserve model file in the same folder as the Conformetrics project, to reduce confusion when sharing or backing up files.
Once the reserve model file has been generated, in the Reserves Summary panel you will see a block model summary for each loaded block model.
Use the Min/Max toggle to inspect the data for missing or rubbish values.
Check the material types, tonnes and grades for ballpark accuracy.
Once you are satisfied, press the blue play button to proceed to the next step.
