|Thundereggs from Deming, NM
|There is an interesting new find from the Deming, NM area. Two very unique kinds of Thundereggs, Lava Cap and
Eggzilla, were named by the two private claims in the Deming area that have found them. The eggs have plumes or
moss formed of calcite with manganese impurities that filled in hollow spots and became embedded in the agate
center. Only a very small fraction of the eggs from the two claims have any embedded calcite, and we were able to
procure one of these unique fluorescent Thunderegg specimens. This is the first one of these we have seen. Both
claims are owned and operated by Lori Coleman who owns Spanish Stirrup Rock Shop in Deming, New Mexico
Excerpt from http://www.agateexpos.com/vendor-information/show-talks/lori-coleman/
“Lori Coleman caught the rock-hounding bug from her late husband Kevin Coleman in the early 80’s in the
Mississippi Delta. They were cotton farmers by trade but spent their spare time walking creek beds to find petrified
wood and walking the farm fields finding arrowheads. Kevin and Lori amassed one of the finest arrowhead
collections to come out of the Mississippi Delta. Later in the 90’s they started planning family vacations to Mt. Ida,
Arkansas to dig for quartz crystals.
Lori and her Kevin retired from farming in January 2009. After studying the topographical maps of southern New
Mexico they decided to move to Deming, New Mexico to spend their days digging for agates. Thus began Lori’s life
as owner of Spanish Stirrup Rock Shop.
Spending a lot of time prospecting for deposits in the Luna County Lori loves spending her time outdoors collecting
or behind the saws cutting. Out of the 6 claims that she currently owns, 2 of the most well known thunder egg
deposits are: Eggzilla and Lava Cap. Needless to say, her passion is thunder eggs.
Lori is licensed and permitted in 2013 through the New Mexico Mining and Minerals Division. She typically attends
two shows: Tucson Az. and Denver Co. however in 2014 she was able to attend the NY/NJ show as well. She was
an Exhibitor at the club show in Denver in 2014 and a speaker also. She will be attending the Agates 2016 Expo as
a Vendor and Exhibitor.
During dig times, it is a family affair. Lori and her 4 children and daughter-in-law all still work together to complete
the process. It was quite a bit easier on her last dig in June 2014 than it used to be because she able to use an
excavator instead of digging by hand. Lori also does all of her own cutting, polishing and just recently took lessons
from world renowned photographer Tom Shearer to photograph her thunder eggs.
She is currently the President of the Chamber of Commerce in Deming, NM and has been featured in the “Deming
Horizons” magazine. A great accomplishment and honor for her was to have not one, but three of her thunder eggs
featured in the “Gem Shop” 2015 calendar. (The month of May). She was also on the cover of the Arizona Wall
Street Journal Feb. 2015 insert. Lori’s Lava Cap thunder eggs is featured in the Mineral-alien Welt magazine March
Lori is currently working with The Friends of Rockhound State Park to build an interactive geology program in
memory of her late husband Kevin Coleman for children, school, groups and individuals who visit the park to dig for
Lori is a constant encouragement to people with interests such as hers, and hopes that they get as much enjoyment
out of rocks, gems & minerals as she does. She tries to live by the motto ‘Do what you love and love what you do.’”

Thunder Egg, Lava Cap
Claim, Little Florida Mtns.,
Deming, New Mexico
|This is a small, unpolished Lava Cap Thunderegg half. It has an outer shell of tan and grey Rhyolite and an interior
consisting of some patches of pale blue Agate and needles of crystalline Calcite embedded in a black Manganese
Oxide mineral. Some of the cavities did not completely fill with either agate or calcite, as can be seen in daylight photos.
Under our 254 nm 13 watt short wave “Way Too Cool” lamp, the calcite needles glow bright red-orange and the agate
bright green, creating a beautiful pattern, and any black manganese oxide is non-fluorescent. Any light blue color in
the SW photo is reflected light from the lamp.
specimen weighs 3.8 oz or 0.23 lbs (108g) and measures 2.4 x 2 x 1.4 inches (6.1 x 5.2 x 3.6cm)
