Overview

The Block Model step allows users to load in block models which can then be used for reporting purposes. This process is exactly the same as the Block Model step in Rapid Reserver.

...

A Reserve Model (file “.resmodel”) 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.

Button	Description
Image Modified	Creates a new Reserves Model (.resmodel file)
Image Modified	Opens an existing Reserves Model
Image Modified	Edit the currently loaded Reserve Model
Image Modified	Removes the currently loaded Reserve Model
Image Modified	Export the currently loaded Reserve Model to CSV

Creating Reserves Model

Loading Block Model

Block Models used to build a Reserves Model can be imported into a project from different formats of various third-party software. Below are examples of importing Block Models in the most common formats: csv and .dat.

Importing from CSV

Press the New button to open the Reserve Model Generator.

Image Modified

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.

Image Modified

Tip
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.

Importing from Micromine

To import a block model in .dat format created in Micromine, select the option “Micromine block Model” and populate Configure Micromine Block Model Settings form.

Image Modified

Specify path to the block model file.
Map block coordinates and sizes fields to the Micromine fields accordingly.

Note

Note
If in the Reserves Model Generator the name of a block model appears red, it means the absolute path to the file can’t be found. The path to the blockmodel must be relinked in order to use it.

Press the folder icon and specify path to the folder where block model file is stored.

Mapping

Image Modified

Once the block model has loaded, its header fields are listed in the Variables panel on the right.

Image Modified

Numeric fields use the N(“field”) syntax, and text fields use the T(“field”) syntax.
Drag and drop the variables to the appropriate field (or double click to map to the selected field).

Image Modified

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 and Logical Operators section to write your own.

For the Volume field use the formula N("DX")*N("DY")*N("DZ").

For the DryTonnes field use the formula N("DX")*N("DY")*N("DZ")*N("Density"), or N("Density") > 0 ? N("DX")*N("DY")*N("DZ") * N("SG") : 0 to exclude negative values.

For the WetTonnes field use the formula N("DX")*N("DY")*N("DZ")*N("Density")/<moisture>.

Be careful to use the text T(“material”) syntax so that the parcel is read as text, not as a number.

Image Modified

Note for Micromine Block Models

When importing Block Models in .DAT format, in the list of Available Variables on the right you will see a new variable MetaN(“Rotation”), which you do not see when working with a CSV file.

Map this variable to the “Bearing” field. This value pulls in rotation data from the Micromine block model, adjusted for Alastri rotation.

Image Modified

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.

Image Modified

Field type	Description	Example
Add Additive button - Sum fields Image Modified	When aggregating multiple block model cells, the value of these fields will be summed together. Sum fields include quantity fields such as volume, tonnes and gold ounces.	Image Modified
Add Weight Averaged button - Weighted fields Image Modified	When aggregating multiple block model cells, the value of these fields will be weight averaged by their parent Sum field. Weighted fields need to be nested under a Sum field.
Add Text button - Class fields Image Modified	Creates subtotals of a sum field, such as Indicated / Inferred / Measured. When aggregating multiple block model cells, these fields behave like Sum fields.

Block Model Formulas and Logical Operators

There are a number of expressions available to use in the Reserve Model Generator.

Expand

title	Block Model Formulas

`A+B`	Add A and B
`A-B`	Subtract B from A
`A*B`	Multiply A and B
`A/B`	Divide A by B
`A.ToLower()`	Convert all upper case text (HG, Hg, hg) into lower case (hg)
`Math.Min(A,B)`	Return the minimum of A and B
`Math.Max(A,B)`	Return the maximum of A and B
`N("density") <= 0 ? 0 : N("volume")`	If density is less than or equal to zero, return zero volume, else return the volume field
`A.Substring(0,Math.Min(3,A.Length))`	Return the first three letters of A
`( RowT("material")=="waste1" \|\| RowT("material")=="waste2" ) ? "waste" : RowT("material")`	If material is waste1 or waste2, then return "waste", else return the "material"

And	&&	If A is "true" and B is "true" and C is "true", then return "true", else return "false"
Or	\|\|	If A is "true" or B is "true" or C is "true", then return "true", else return "false"
Equal to	==	If A is equal to B, return "true", else return "false"
Not equal to	!=	If A is not equal to B, return "true", else return "false"
Greater than	>	If A is greater than B, return "true", else return "false"
Greater than or equal to	>=	If A is greater than or equal to B, return "true", else return "false"
Less than	<	If A is less than B, return "true", else return "false"
Less than or equal to	<=	If A is less than or equal to B, return "true", else return "false"

Custom Variables

If required variable is not available, you must create/edit it in the Script Editor window, which can be accessed via the Custom Variables button.

Image Modified

Press the Custom Variables button.
In the Script Editor window, customize the formula code.
You can copy sample scripts from the SC. Block Model Custom Variables section and paste them into the Editor window.
Change the required values, such as the parcel and thresholds.
Verify that the code is correct by pressing the Compile button.
If there are no errors, click OK.
The new custom variable will appear in the Variables list on the right in bold. Drag and drop it to map it to the applicable field.

Reserve Field Value Clamping

Use Minimum and Maximum columns to clamp numbers by block to be >= Minimum and <= Maximum.

This functionality can be used to help with data hygiene by ensuring that values are somewhat sensible.

Image Modified

Recommendation

If the value in the Minimum column is set to a negative value, the Reserves Summary and subsequent data may incorrectly display the material contents or other inputs as negative values.

Image Modified

Tip
To prevent showing negative values, in the Minimum column, limit the lowest values to zeros. This way, even if minus values (-99 or -∞) are used in the Block Model fields, you will not have negative values displayed for reserves during further setup and scheduling.

Image Modified

Exporting Mapping

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 and Export Fields buttons are used for this purpose.

Image Modified

Find and Replace

You can also use the Find and Replace button to speed up the filling of similar parameters in copied mappings.

Image Modified

Errors List

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

Image Modified

Recommendation on files storing

Tip

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.

Reserves Summary

Once the Reserve Model file has been generated, a 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.

Image Modified

Export

You can export the entire Reserves Model to a CSV file. To do this, click the Export button on the top line and specify the path to the destination folder.

Tip
The new CSV file will contain all Block Models, with all the blocks and all the fields existing and added by the user.

Image Modified

You can also narrow your Block Model Data export by selecting which parcels and fields you wish to export from the Reserves Summary.

Image Modified

Selected parcels and fields of the Reserves Model can be exported to Excel or to Text/CSV formats.
