This passage struck me as well.

The idea of an open source model for a deposit is interesting indeed. Without going into detail, you would need someone with a GEMCOM license (or comparable modelling software, all in the $30k range) as well as some experience in modelling to "moderate" or create the model for the community.

Someone really motivated could do it....

Or someone really motivated could pay a modelling firm to do the work based on the info that is available in the public domain.

Anyways..... just my 2 cents.
