Load block models in the Block Model step.

Default block model step.

Quick Notes:

  • A reserve model is a collection of block models.

  • Each project loads a single .resmodel file at a time.

  • The New and Open buttons create and load reserve model files.

  • The Edit button is where block models may be added or removed from the reserve model.

Create a Reserve Model

Press the New button to open the Reserve Model Generator.

Select Import > CSV file > myblockmodel.csv

  • 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.

Once the block model has 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.

Map the block model fields to the reserve model fields.

New reserve model fields can be created by clicking the sum, weighted, and class icons located in the top button ribbon. These add new rows into the field list.

  • Sum fields are summed together, such as volumes, tonnes, and gold ounces.

  • Weighted fields are weight-averaged by their parent field, such as iron percent or gold ppm.

  • Class fields create subtotals of their parent fields, such as tonnes of 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.

Press Generate to build the reserve model.

If the Errors panel is blank, and all relevant fields are mapped, press Generate to build the reserve model.

Always save reserve model files locally (or on the same server on which Rapid Reserver is running). When sharing work with a colleague, the Rapid Reserver file and the reserve model file should be shared together.

Once the reserve model file has been generated, a block model summary is displayed 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.

Use the block model summary table to inspect the data before continuing.

Once your are satisfied, press play to the next step.
