In the Block Model step you will be prompted to load your block models from Surpac (.mdl), Vulcan (.bmf), MineSight (.dat) or Micromine and convert it to Alastri Block Model formal (which is .resmodel).
Within Alastri’s resmodel we can take multiple block models and convert them to a common structure, common framework, with same number of fields and same fields in terms of their names.
Within a single resmodel we can have multiple block models, what makes it a lot easier to store the information.
Note:
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.
Press blue plus icon and 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.

When importing Block Model CSV, you’ll see a preview of the first 100 rows of this CSV. It's a good time-saving feature, as your site Block models CSVs can be of a very large size and take a long time to open. |
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.
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.
Create and map the fields for Fe, Al, Si, P, Mn, LOI, and S.

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.
To facilitate the matching of fields of similar block models, the filled fields of one model can be copied and pasted into the other. The Copy Mappings button is used for this purpose.
You can also use the Find and Replace button to speed up the filling of similar parameters in copied mappings.
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. As such, a good rule of thumb is to save the reserve model file in the same folder as the Rapid Reserver project, to reduce confusion when sharing or backing up files. |
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.
Once satisfied, press blue play button to proceed to the next step.
