There exists, in certain places around the world, areas that for one reason
or another, produce the most amazing assortment of minerals. These sites
are well known to mineral collectors everywhere. The ones mentioned here,
are just some of those fabulous localities.
These sites are special for a number of reasons. They may be the type
locality for a number of rare minerals. A 'type locality' is a site were
the first specimens of a mineral were discovered and identified as a new
mineral species. Most of the sites mentioned here are type localities for
several hundred new mineral species. They also could be a place where literally
hundreds of different mineral species are found. Such a site is very scarce since most mineral sites rarely have a dozen different minerals. They also may be a site that produces the very best crystals or
unique crystals, such as twins or exquisite gemstones. And finally, these sites may have just produced
specimens at such amazing quantities that they are to be commended just
for providing the average collector with an opportunity to possess such
lovely collection pieces at affordable prices.
They are not however, just mines that produce thousands of tons of ore.
While these sites may be special to miners and of economical significance,
they are not so special to mineral collectors unless they have produced
numerous, new, special, rare and/or well crystallized mineral specimens.
They are also not one mineral wonders. Such sites may have made a name
for themselves with spectacular and numerous specimens of one mineral or
another, such as Mt. Ida, Arkansas' wonderful examples of quartz
clusters or Dundas, Tasmania's colorful and exotic crocoite
specimens, but these sites lack the diversity of species that is required to make
this list. The following list is large enough as it is.
There are hundreds of wonderful mineral locations that deserve adulation
and all can not be mentioned. Nor is there any attempt to signify an order
of importance. Both active and inactive sites are listed because even inactive sites may still have specimens on the mineral market and these sites are not forgotten so easily.
Links to some of the sites give more detailed information
and at least a partial list of the significant minerals that have been found there.
If a site is not mentioned and you feel it deserves mentioning, please

form with the information of the site and why it should be included.
The locality from where a mineral is found is not so much a physical
property as it is a condition of the environment of formation for
a particular mineral. However, this can be an important asset in correctly
identifying a mineral. Especially if the site is known to produce a very
unique mineral. It is very important to keep accurate records for all specimens
even if identification is considered conclusive and always try and obtain
the exact locality from dealers when you purchase specimens.
The follow sites are just some of the most wonderful mineral localities
in the world:
The Arizona copper mines, USA -
- These localities are the result of the supergene enrichment and hydrothermal
alteration of a porphyry copper sulfide intrusion. Although a good source
of rare minerals, it is the fantastic assortment, quantity and quality
of the more common minerals that sets the mines in this state apart from
most other copper deposits. The malachite, azurite, turquoise, wulfenite,
chrysocolla, cuprite, hemomorphite, kinoite, rosasite and aurichalcite
specimens alone are truly inspiring.
The Bancroft, Madoc and Wilberforce areas
of Ontario, Canada
- This assemblage of minerals is the result of a chemically unique igneous
intrusions, altering the country rock (mostly impure limestones), by way
of complex contact metamorphic interactions and it is these wonderful mineral
sites that are the end products.
Black Hills region, Custer County, South
Dakota, USA
- A great mineral assemblage of rare and new phosphates form a phosphate rich granitic intrusion.
The Bombay area mines, India -
- A collectors treasure trove of apophyllites, cavansites, zeolites and
their unique suite of associated minerals.
The boron mines of California,
USA -
- These unique deposits are the result of boron rich hot spring fluids
flowing into playa lakes and evaporating in the semi-arid/arid environment leaving
wonderfully unique boron, carbonate and sulfate minerals behind.
Broken Hill, New South
Wales, Australia -
- Produces a wonderful set of lead, copper, silver and other ore minerals
and their associated rarities.
Copiapo and Atacama Desert, Chile -
- A nice assortment of arid region minerals especially rare halides.
Cornwall and Devon, Durham mining areas,
England -
- These classic mines have produced some of the most fantastic mineral
specimens to grace museum collections and display cabinets of collectors
all over the world. Although nearly depleted now, these mines have been
worked for centuries for silver, tin, lead, copper, iron, tungsten and other ores.
Over 300 different mineral species are known from these
mines and many are only found here or were first discovered here.
Cobalt, Ontario, Canada -
- Named for the metal found in many of its unusual mineral types, it
is also known for silver and rare silver minerals that were extensively
mined here.
Francon Quarry, Montreal, Quebec, Canada
-

and unique specimens of exotic species such as the famous
weloganite as well as
dawsonite,
dresserite,
franconite,
hydrodresserite,
montroyalite,
strontiodresserite,
sabinaite,
cryolite,
strontianite
and more.
Franklin and Sterling Hill, New Jersey,
USA -
- Once a strategic mining area for the steel strengthening metal manganese
and the always important iron and zinc, it is now just a museum.
It has produced hundreds of exotic manganese, zinc, iron and cobalt minerals,
many first described from here and some known only from this mine.
The manganese often acts as a
fluorescent
activator in several mineral species making the mines and many specimens glow like a fluorescent rainbow under ultraviolet light.
No other place is like this!
Southern Greenland -
- Famous agpaitic pegmatitic intrusions near Narsarsuk and Ivigtut have produced many new mineral species.
