The latest version of PolyMap now includes the ability to take 2-D polygon shapes on sections or plans and tie them together to form standard 3-D wireframe models.

New changes are completed with the Varigram Modeling and Display program.  The user can easily fit nested models to experimental variograms, using simple mouse drags up and down for sill/nugget adjustment, and mouse drags side to side to adjust the range.  Immediate feedback is given.  This greatly speeds up the process of fitting models to the experimental data.

New changes were recently made to MicroMODEL which allow the user to display presentation quality histogram plots directly from the various statistics programs.  Also, the statistics programs were upgraded so that statistical values can be calculated based on weighting factors.  The most common use is with the declustering weights that are generated by the MicroMODEL version of GSLIB’s DECLUS program. In addition, the plan view and section view display programs were updated so that slices through a third party generated wire frame model can be easily displayed.

We are currently beta testing new features that will shortly be added to MicroMODEL.  Included are the ability to “slice and dice” outlines from 3-D wireframe models generated by other software packages, easier section location plotting in drillhole plan views, and new choices for assay interval compositing.

We welcome Mr. Carl Brechtel, C.O.O. of International Tower Hill Mines, Ltd. and Mr. Mike Anderson, Operations Manager for Lowham-Walsh LLC as our newest MicroMODEL and PolyMap users.  Both of these gentlemen have previous experience with some of the more expensive modeling programs, but they chose our software because of its excellent value.

Declustering Data

The GSLIB program DECLUS, which declusters sample or composite data, was recently adapted to the MicroMODEL statistical toolbox.  In addition, the programs that display cumulative frequency plots and correlation plots were upgraded to include some nice presentation quality single page outputs.

A new version of EZVol, Version 8.0, is available as a demo for beta testing.  The new version adds the following:

1) Windows 7 compatability

2) Save/Retrieve stockpiles from multiple folders

3) Remembers last twelve folders containing stockpile analysis

4) Remembers last screen location and size on startup

5) New 3-D viewer allows user to view stockpile shape in shaded 3-D view, with mouse click “spin” controls

3-D LG Pit Otimizer

Published on 21 June 2010 by in Mining Planning Software

We are in the final stages of testing the MicroMODEL interface to the ThreeDify Flowpit program.  This program generates optimal mining shells using a true 3-dimensional Lerchs Grossman algorithm.  A Flowpit license can be purchased for use with any current MicroMODEL for $1700.  There is a yearly maintenance fee for the Flowpit program of $500 per year.

So far, preliminary tests have shown results of the Flowpit program agree to well within one percent of the final shell generated by the Datamine MaxiPit ™ program.  Check the prices and you’ll see that the Flowpit option offers significant savings over any other optimizer on the market today!

The MicroMODEL Money Matrix program is used to generate the appropriate input files to Flowpit, and all Flowpit output is converted back to MicroMODEL surface grids.  If you already know how to run MicroMODEL floating cones, then you know how to run Flowpit 3-D LG optimizations.

Please contact us for more information, or to purchase your license.

The OPCOG/SCHED program suite has been recently revamped.  The SCHED program allows the user to automatically schedule a set of mine phases, based on yearly targets.  Ore can be scheduled by tons mined per year, or by pounds/grams/ounces of recovered product.  Waste requirements can be forward smoothed in order to minimize fleet size changes.

Once a mine schedule has been produced, the Optimum Cutoff Grade program (OPCOG) can be used to optimize project net present value via a variable cutoff grade strategy.  The optimizer uses an algorithm based on the works of R. K. Lane and M. R. L. Blackwell.

Several iterations can be made between the scheduler and optimizer in order to produce a physically feasible mining sequence that optimizes the net present value of the mining operation.

If you have an interest in these programs, please contact us directly.  There is currently an interface to both the MicroMODEL and MineSight software systems.  New interfaces can be constructed at a nominal cost to the user.

On 12/30/09, a MicroMODEL user group meeting was held at the offices of TetraTech in Lakewood, Colorado.  Attendees included Don Tschabrun of Jipangu Resources, John Ziese and Don Hulse of Gustavson Resources, Rex Bryan and Lee Aga of TetraTech, and Randy Martin of RKM Associates.  Plans for updating MicroMODEL were discussed, including expanding certain geostatistical modeling capabilities, handling of rock code inputs, and improved menu navigation.  Don Tschabrun presented results from the new variable slope by rock type cone miner output.  This new feature allows the user to vary the slope, not only by azimuth, but also by rock type, when doing pit optimization studies.
