The
Highland Centennial Gold Nugget
The Mineral Museum is the home to the Highland Centennial Gold Nugget weighing
27.5 troy ounces. The nugget was found by the Stratton family in 1989 while
placer mining in the Highland Mountains south of Butte. The nugget is believed
to be the 7th largest gold nugget found in Montana.
The Rheanna
Star
An incredible smoky quartz cluster over two feet in
diameter, was discovered by Zach Johnson near the Delmoe Lake area. The Museum acquired the "Star" in June 2009 and it is now on permanent display
in the Mineral Museum.
Minerals
from Butte and other Montana localities
Butte was once home to one of the biggest copper mining operations in the
world and was known for ‘electrifying’ America during the late
19th century and early 20th century. The Mineral Museum has spectacular specimens
from the underground mines, including the copper minerals
such
as bornite, enargite, digenite, and covellite, and other minerals such as
rhodocrosite and molybdenite. The underground mines closed in 1978. Open
pit mining continues today in the Continental Pit.
Modern Mining
Known as the “Treasure State”, Montana continues a
long
tradition of mining. Copper, molybdenum, gold, talc, and various rock are
commercially important and collectors seek out minerals such as agate and
sapphires.
Fluorescent
Minerals
The Fluorescent Mineral room provides a stunning display of minerals under
short wave and long wave ultraviolet light. When exposed to certain wavelengths
of light, some minerals fluoresce. See how the mineral halite (also known
as salt) changes when viewed under ultraviolet light.
Touch
and Feel
Large specimens of minerals are scattered throughout the museum for visitors
to touch and examine up close. Specimens
include
a large amethyst quartz geode from Brazil, and a giant smokey quartz crystal
from the Butte area affectionately called “Big Daddy” which
weighs 397 pounds.
