Configure Local Topcut Transition Model Properties

The Local Topcut tab provides parameters for configuring the Local Topcut Transition model.

Activity Steps

1. Select the Local Topcut Transition component in the Project Tree.
2. Select the Local Topcut tab in the Property Panel.
3. Configure the following options as required.
   • Current Settings field group:
     • Current maximum grade – Maximum grade in the dataset. This field is read-only.

       Note: Any global topcuts defined further up the tree impact the value shown in the Current maximum grade field.

     • Topcut from global topcut analysis – Topcut defined by the Global Topcut Analysis, if available. This field is read-only. This value can be changed in the Global Topcut Analysis component.
   • Analysis Parameters field group:
     • Transition Range – The degree of topcut increases until the distance specified here is reached. Beyond this distance the global topcut is applied to the sample grades.
     • Set topcut beyond range – Topcut that is applied once the specified distance from the block centroid has been reached. All samples beyond the specified distance are topcut to this value.
     • Use global topcut analysis – The topcut applied once the specified distance from the block centroid has been reached is taken from the Global Topcut Analysis, if one is available. Only available if a relevant Global Topcut Analysis exists in the project.
     • Transition Factor – Rate of transition across the centroid to the sample distance. The higher the transition rate, the slower the rate of topcut applied.
     • High grade dampening effect – Minimum proportion topcut applied, regardless of the transition rate.

       Note: Several of the Analysis Parameters above can also be set on the Local Topcut Transition plot. See Local Topcut Transition Model Plots.

   • Number of highest samples to display – Number of samples displayed on the percent metal graph (highest to lowest). The maximum number of samples that can be displayed on this graph is 30.

     Note: Setting a global topcut using the @ filter method impacts the Percent Metal Per Highest Grade Samples plot. The top 30 highest grades may all have been reset to the value you entered at the global topcut level.

   • Selected test grade coordinates table – Shows the X, Y and Z coordinates for any point selected on any of the displayed plots.
