Merger and Acquisition Due Diligence
Field Support
Prior to joining RJ Lee Group, Mr. Linder was previously employed by Vulcan
Materials Company where he most recently served as Manager of Geological
and Mine Planning Services. His duties included scheduling geologic and mine
planning projects, evaluating potential acquisitions, and ensuring compliance
with federal regulations. Mr. Linder holds an M.S. in Economic Geology and
Mineralogy as well as from the University of Maryland College Park, and an
undergraduate degree in Geology from the University of Maryland College Park.
RJ Lee Group is an industrial forensics laboratory that is recognized as a leader in

2. MAJOR ISSUES
Overburden & Weathered Rock Distribution and Thickness
Ensuring Material Meets State Specifications
Discovery and Avoidance of Asbestos, Heavy Metals
Water Inflow to Pit or Quarry
Growth and Exploration for New Opportunities

3. Basic Steps and Purpose of Modeling/Exploration
1) Information & Data Gathering - Search for all sources of
information related to the site to be modeled or area to be
explored for new opportunities.
2) Forensic Geology – Assemble all collected data regardless of
condition into a complete, comprehensive, and internally
consistent digital database.
3) Critical Thinking - Evaluation of data and preparation of
graphical displays of data for mapping purposes.
Old Core Hole Location Maps
Old Literature Hand Sketches
Core Evaluation and Sampling
Old & New Aerial Photography
Old & New Geologic Mapping

4. Basic Steps and Purpose of Modeling/Exploration
1) Hand Mapping – Initial basic geologic mapping of any sort,
e.g. structural, thickness, quality, etc. is done by hand using all
available collected information and data and by using
advanced knowledge of geologic principles.
2) Creation of a Digital Database– Digitization of one’s
mapping enables transformation into a digital format. By
deriving this digital mapping from hand made maps and critical
geologic thinking, there now exists a much more thorough and
refined understanding of the issue at hand than using
scattered and inconsistent pieces of data.
1) Computer Modeling – Once mapping exists as digital data,
maps and/or cross-sections can be generated and customized
depending on need. This data can also be used to generate 3D
digital geologic block models.

5. Basic Steps and Purpose of Modeling/Exploration
1) Support for Mining Engineers- With a geologic block
model complete, multiple scenarios can be generated to most
closely estimate the total reserve which can be extracted.
Additionally, the most cost effective progression of mining can
be determined.
2) Support for Geologists – These models and the graphical
products that can be generated aid geologists in further
mapping, prediction and adjustment or quality checking of the
subsurface model.
3) Support for Marketing and Sales – With detailed exploration
maps in hand, the search for new growth opportunities is
made easier. The compilation of multiple data types enhances
the ability to strategically seek out greenfields, acquisition
targets, or company mergers.
4) Support for RJ Lee Group Understanding of the sub-surface
geology will greatly enhance the ability for proper sampling of
ledge rock, stockpiles, dust, etc. for materials determined to
be deleterious to one’s health. This includes, but is not limited
to asbestos, silica, heavy metals.
