Welcome to the Winter 2003 Issue of the
GoldSim Newsletter! Published
quarterly, our goal is to provide information that helps you
get the most out of GoldSim. We also hope that the Newsletter
can act as a vehicle to build connections between users within
the GoldSim community.
Each newsletter delivers the latest
GoldSim news, as well as a number of regular items. This includes
a Featured GoldSim Application, tips from the GoldSim developers,
a list of new models added to the GoldSim Model Library, a
list of new GoldSim Knowledge Base articles, and a description
of new features that the GoldSim Development Team is currently
working on. Each Newsletter is archived on our website so
you can revisit old issues.
Since this newsletter is for you, we
encourage you to send us your comments and contributions.
If you send us a contribution and we use it, we will acknowledge
you in the Newsletter. Send your contributions to firstname.lastname@example.org.
The GoldSim Technology Group
Second Annual GoldSim User Conference
We are pleased to announce that the second annual GoldSim
User Conference will be held in Seattle, WA USA on June 19-20,
2003. Prior to the conference, we will offer a two-day GoldSim
training course for new GoldSim users on June 17-18, 2003.
Also, for existing users, we will offer a set of advanced
training seminars on Wednesday, June 18. The User Conference
and the training will be held at the Washington Athletic Club
in the heart of downtown Seattle.
GoldSim Academic User Community
We are also pleased to announce that we are forming a GoldSim
Academic User Community. Once the community is formed, we
plan to provide the following academic resources on our website:
list of Academic users, list of papers that reference GoldSim,
and model files prepared by academic users. It is our hope
that these resources will facilitate further communication
between members of the Academic community.
If you are an Academic user and are interested in becoming
a member of the GoldSim Academic User Community, please contact
us via email, email@example.com,
and provide us with the following information:
to personal website or the website of your University or your
description of area of interest.
email address to be listed in the Academic User Community.
of papers that reference GoldSim (either published or working
papers) that you would like to have added to our list of academic
files with a description that you would like to have added
to our Model Library.
GoldSim Releases Service Pack SP-1 for GoldSim V. 7.51
GTG released one service pack, SP-1, in early January. SP-1
addresses the following issues:
problem with hyperlink components, which did not always function
correctly when embedded in dashboards.
when cloning Material Time Series, Information Time Series,
Sum, Extrema, Fluid and Source elements.
problem with constant date/time strings (e.g. "01/01/2003")
in input expressions. GoldSim mistakenly requested a unit
string to be added to the date.
problem with memory buildup while running complex models.
problems with large system fonts.
CT/RT-module now gives better convergence in problems involving
low-solubility, low-mobility species.
This service pack is available for all current members of
the GoldSim Upgrade and Support program.
GoldSim Online Help is on the Way!
We are very close to finishing the online GoldSim Help system.
This Help system essentially contains all of the information
that is currrently in the printed User's Guide, but adds powerful
navigation capabilities (including keyword and full text search,
related topics lists, and hyperlinked cross references). In
addition, the Help system is context sensitive - Help buttons
in GoldSim dialogs will link to the appropriate topic in the
To complement the Help file, the User's Guide is also being
updated. The main changes you will see there are that the
page numbers no longer include chapter numbers, a detailed
index (with over 1000 entries) and glossary have been added,
and cross-references within the document have been made easier
to spot. These will all make the manual easier to use as a
We will send a separate announcement to all users when the
Help file and updated User's Guide (a PDF document) are available
GoldSim Enhances the Environmental Assessment of the DeBeers
Snap Lake Diamond Mine Project

Associates, Mississauga, Canada

Associates, Guelph, Canada
Before a new mine can be developed, it is necessary for an
environmental assessment (EA) to be completed and accepted
by the regulatory agencies responsible for project approvals
and licensing. Recently, De Beers Canada Mining Inc. (DeBeers)
submitted an environmental assessment study for a major new
diamond mine in Canada's Northwest Territories. This study
relied on an integrated GoldSim model to assess the impacts
of mining and site activities on site water quality.
The successful completion of EAs for large scale development
projects requires the involvement of a large number of technical
specialists and the communication of detailed scientific data,
calculations, findings and conclusions to the regulatory agencies.
Geologists, geotechnical engineers, hydrogeologists, hydrologists,
geochemists, biologists, toxicologists, etc., each provide
input based on their respective areas of expertise, and their
inputs must be integrated in order to assess the overall environmental
impact of the proposed development. The integration of the
technical information, and the ability for others (e.g., regulators)
to understand and review the assessment, is an extremely challenging
task. From a technical perspective, over-simplification of
the linkages between the various types of information can
erode the technical quality of the assessment and therefore
the quality of the decisions made on the most suitable manner
in which to develop the project. From a process perspective,
a lack of clarity or transparency in the calculation methodology
will lead to lengthy reviews, increasing the time (and costs)
required for regulatory approvals.
Our development team is working hard on some features that
will show up in GoldSim later this year. Here's a sampling:
We're beefing up the ability to import graphics and make your
models look great.
We're developing some new utility elements: a simplified Table
element, a 'chance-node' element that will select an output
at random when a triggering event occurs, an element to evaluate
complex logic trees, and others.
We're adding some specialized elements to help you model the
reliability of complex systems, including dependencies and
We're adding an ability to let you iterate a part of your
model at each time step, either for a specified number of
iterations or until it meets a convergence test.
We're prototyping the Spatially-Distributed Module, which
will allow users to create models that are replicated across
a map. This should be a very powerful tool for modeling ecosystems,
urbanization, or other spatial systems.
We're also planning to add a Financial Module, which will
let you add powerful accounting and financial-statement capabilities
to models that involve money.
If you're interested in helping us to test any of these capabilities,
please send us an email at firstname.lastname@example.org.
You may have to put up with a bug or two, but you'll be able
to provide input and your assistance will be greatly appreciated.
We'd also appreciate any suggestions that you might have for
new GoldSim features!
