Title:

A Microsoft Windows Version of the MARK3 Monte Carlo Resource Simulator

Abstract:

This publication includes a version of the MARK3 Monte Carlo resource simulator that will run under Microsoft Windows 98, NT, and 2000. The disc also includes grade and tonnage information and related deposit model files that allow the user to calculate probability curves for mineral resources. A total of 113 deposit models are included on the disc although some of them are subsets of others. In most cases the list of deposits with associated grade and tonnage data are also present. Ten of the models contain proprietary information and the grade and tonnage for those are not included. The program also includes an extensive help file that provides information about the program and about the concepts that are the basis of the program and about this method for estimating quantitative mineral resources.

   Data sources used in this process:

   • Root and others, 1992

1. How well have the observations been checked?

   Various tests were made to ensure that the program is functioning correctly. The input deposit models, both empirical and logarithmic, were reproduced when a single deposit is allowed. The random number generator was tested to ensure a flat histogram with 100,000 numbers.

2. How accurate are the geographic locations?

3. How accurate are the heights or depths?

4. Where are the gaps in the data? What is missing?

   Most of the economic minerals are represented by various deposit models.

5. How consistent are the relationships among the observations, including topology?

   The deposit models are based upon grade and tonnage information from a variety of authors and sources. The calculated results approximately reproduce the tonnage curves. Results were compared to the original FORTRAN program and the calculated values match within numerical accuracy limits.

Are there legal restrictions on access or use of the data?

Access_Constraints: None

Use_Constraints: None
