What's new in Cognomine
New planning features, newest first. To see Cognomine run, see the demo or read how Cognomine works.

Target-grade planning
Many deposits, such as iron ore, are sold to a grade specification rather than maximised on grade. Mark one stream as target grade and set the range plant feed must stay inside each month. The plan sequences mining and builds stockpiles to keep the blended feed in range. Where it pays, stockpiles are split into clean and dirty pads, so less ore is discarded than with a single fixed blend.
Contaminant limits
Mark one stream as a contaminant, such as phosphorus in iron ore or arsenic in gold, and set a maximum feed grade. The plan keeps each month's plant feed under that limit, in target-grade projects and in maximise-value projects. The results flag any month that falls outside a range or limit, with mean and worst feed grade, so you can see how much room the constraint leaves.
Variable pit wall slopes
Set a default wall angle, then override it by block using your model's own fields. Weathered material or a particular lithology can take a flatter wall and competent rock a steeper one. The pit and the schedule both respect the angle of the rock being cut. Slopes by sector or wall direction are not supported yet.
Variable recovery
Each ore stream has a default recovery. Override it by rule, such as grade below 0.3 at 60%, or read each block's recovery from a column in your model. Recovery is applied once, when the model is imported, so pit selection, scheduling and the financials all use the same recovered metal.
Waste dumps built to a slope angle
Dumps now use a slope angle, 17 degrees by default, in place of a fixed block-count window.
Setup guide
A field-by-field guide in Help explains every setting in the setup wizard.
Existing projects: financial results are recomputed when you open a saved run, so NPVs may differ from what you saw before.
