16 th, February, 2010
Topic: Marigold Mine, Valmy, NV.
Summary:
During the period 1981-1983, Larie Richardson was working for Vinnell Mining & Minerals and was supervising a heap leach gold mine.
He became interested in the technology and realized that having one's own gold mine was now possible and feasible for a small miner with
the right know-how. He built an experimental carbon plant in the backyard of his parent's home, acquired the appropriate accessory
technology, and with a trusty partner, set out to find a property to utilize the technology and equipment. The result was the Marigold Mine
near Valmy, Nevada. Larie's PowerPoint presentation will show and demonstrate the mine development including about 90 photographs taken
during the initial development.
Speaker: Larie Richardson, General Manager, North Star Minerals Inc., Arcadia, CA.
Background: Larie Richardson is the General Manager and Owner of North Star Minerals Inc.
He took his first course in Geology in 1958, and has two degrees in Mineralogy/Petrography from the University of Nevada-Reno.
He has worked for the State of California, Battle Mountain Mine, and Vinnell Mining & Minerals in NV. Later starting his own companies:
Nevada North Resources, and North Star Minerals Inc. He has been a member of SME since 1975.
Meeting Format: Social
hour is from 6:00 pm to 7:00 pm, Buffet Dinner begins about 7:00
pm. After the dinner, section business is attended to, a raffle
of several bottles of wind is conducted and the presentation is
given. Proceeds from the raffle support the GEM Committee
activities. The Dinner cost is $30/person. To Be Held At Pomona Valley Mining Co.,
Pomona, CA

16th, March, 2010
Speaker: Dr. Jeff Gillow, Principal Geochemist, ARCADIS, Highlands Ranch, CO.
(SME Henry Krumb Lecture Series Speaker)
Subject:
Characterization of Arsenic Geochemistry in the Mojave Mining District of California
Background: Dr. Gillow is currently a Principal Geochemist at ARCADIS, U.S., Inc.
and is focused on serving clients in the mining and industrial sectors with innovative, and technical based solutions to complex
environmental issues. He has over 20 years of experience working on source control and water quality at mine sites, environmental
stewardship of the nuclear fuel cycle, and management of energy byproducts. Dr. Gillow has a PhD. in Environmental Science & Engineering,
Colorado School of Mines, an MS in Environmental Science, State University of New York, and a BS in Aquatic Chemistry, Southampton College.
Prior to joining ARCADIS, Dr. Gillow was an Associate Chemist at Brookhaven National laboratory performing research and development on
technologies for management of mine, energy, and nuclear waste materials. His expertise is arsenic and chromium geochemistry, as well as
prevention and treatment of acid rock damage and associated metals. His practical experience centers on geochemical investigations and
baseline water quality studies as well as control and treatment of sources of metals and acidity. He has worked on geochemical stabilization
of arsenopyrite to prevent acid and arsenic release in oxidizing environments, and has investigated the basis for arsenic stabilization
under anoxic conditions. He is principal scientist on current projects including the optimization on in-situ reductive precipitation of
chromium in aquifer systems, as well as bio-geochemical approaches for treatment of uranium and sulfate in groundwater. He has employed
sophisticated analytical chemistry methods to understand the mineralogy and geochemistry of metals and metalloids in ore, waste rock,
and environmental samples. These include electron microprobe and x-ray spectroscopy as well as sequential selective chemical extraction.
His approach to evaluation of source control involves detailed characterization, conceptual model development, and fate and transport
assessment. He is well versed in all of these aspects of environmental evaluation for mining projects.
Summary: Past mining activities in the Mojave Mining District have resulted in the
accumulation of historical tailings from the recovery of precious metals. Rock types in the District include rhyolite, rhyolite porphyry,
quartz latite, and pyroclastics with ore present as epithermal fissure veins containing gold and silver minerals, as well as minor pyrite,
galena, and chalcopyrite. The Mojave area is characterized by arid conditions, and the rock has a very low acid generation potential; water-rock
interactions are not of paramount concern. Prior to new mining activities in the area, a baseline study was performed to characterize the
historical tailings and the occurrence of arsenic in order to understand its form and environmental mobility. The study included comprehensive
sampling and analysis of ore, waste rock, tailings and soil, as well as advanced mineralogical analyses. A conceptual geochemical model was
prepared to describe the forms of arsenic in association with iron oxyhydroxide weathering products. The model was validated through mineralogical
characterization, including leaching testing and ion-beam microprobe analysis to examine the association of arsenic with forms of sulfur and iron.
This characterization of previous mined areas, prior to new mining operations, as well as materials from host rock and leached ore, provides a
comprehensive understanding of arsenic, its chemical form, and environmental stability.
Meeting Format: Social
hour is from 6:00 pm to 7:00 pm, Buffet Dinner begins about 7:00
pm. After the dinner, section business is attended to, a raffle
of several bottles of wind is conducted and the presentation is
given. Proceeds from the raffle support the GEM Committee
activities. The Dinner cost is $30/person. To Be Held At Pomona Valley Mining Co.,

Marble Quarries of Carrara, Italy, and Vermont, USA
SPEAKER: Dr. Erik Melchiorre, Associate Professor of Geology, CSU, San Bernardino.
Summary:
For over 2000 years, the fine white to gray marble from the Apennine Mountains of the
Tuscany Region of Italy has been mined. The Carrara Marble is world famous, and graces many
important buildings around the World. It is commonly seen in the USA as the white marble threshold
in public restrooms. The presentation will have video and slides showing the ancient Roman quarries
and mining methods, and more modern mining operations, with a report on the state of the industry.
There will be a special section of the presentation, detailing the processing of marble and yielding end
products, including the operation of massive diamond saws that cut up to 20 "counter top" slabs. The
town has long held a special place in the hearts of sculptors, from Michelangelo who used it for his
famous work, to modern artists. The methods used in sculpting marble will be explained. Samples of
Carrara Marble will be available to examine. For centuries, Carrara has produced not just stone, but
also the men with the skills to work it. Dr. Melchiorre will complete his presentation with an
examination of the role of Italian stone masons in the founding of the Vermont quarry industry.
Background:Dr. Erik Melchiorre is Associate Professor of Geology at California State University,
San Bernardino. Prior to working in academics, he served in the U.S. Army and worked as a geologist
for Phelps Dodge at the Morenci Mine in Arizona, and for Cyprus Minerals at the Bagdad Mine,
Arizona. He has also worked at several summer student jobs including the silver mines of the Coeur
d'Alene in Idaho, and the Homestake Mine of South Dakota. Erik has just returned from a research
sabbatical. During this sabbatical he traveled around the world visiting mining operations, including
the Marble Quarries of Italy and also Vermont.
Meeting Format: Social
hour is from 6:00 pm to 7:00 pm, Buffet Dinner begins about 7:00
pm. After the dinner, section business is attended to, a raffle
