SWEET 2 LB 3 OZ BONANZA SILVER ORE SLAB: FRONTIER MINE, COBALT, ONTARIO, CANADA!

Description

Here is a really cool specimen composed of a 8 to 11 mm thick vein section slab of very rich silver and cobalt ore growing through a light colored dolomite-calcite matrix.  There is a lot going on with this piece and it deserves a good long look under a hand lens to unlock all this piece has to offer.  This is a slab cut from a much larger piece and both large sides and two edges have been cut flat, but not polished to show the internal ore composition while the other edges have been left natural.
So taking a close look at this piece, all the really bright silver-white areas you see in the photos are native silver with silver-gray cobaltite and maybe a few other sulfides and arsenides running through a primarily light colored calcite-dolomite matrix.  But there is very little calcite-dolomite left, most of the specimen is silver and cobalt minerals.  All the bright nearly white stuff in the photos is silver and all the darker silver-gray stuff is primarily cobaltite, and all the cream to light gray is calcite and/or dolomite!  I would estimate this piece is composed of about 30% calcite-dolomite, 30% native silver and 40% cobaltite and other sulfides.  We know that silver is roughly 3.8 times as heavy as calcite and 1.5 times as heavy as cobaltite.  So if the percentage breakdown by volume above is correct, the specimen would contain roughly 46% of its weight in silver.  The total specimen weighs in at 35.3 ounces, meaning there would be roughly somewhere around 16 ounces of silver in this slab ounces of silver in this specimen.  Its bonanza grade for sure.  That equates to over 14,000 ounces of silver per ton and at the current silver price of .19 per ounce this piece contains somewhere around 0 in silver value alone!
This piece was cut from a 50 pound section of ore from the famous Woods Vein at the Frontier Mine, South Lorrain Township, Cobalt-Gowganda Region, Timiskaming District, Ontario, Canada.  This is a large cabinet sized specimen that is a slab cut on the top and bottom and two thin edges and ranging from 8 to 11 mm thick and overall it measures 19.0 x 10.7 x 0.11 cm in size (about 7.5 x 4.25 x 0.4 inches), it weighs 2 pounds and 3.3 ounces, and it comes professionally labeled and ready for immediate display!   This is a big, beautiful classic locality super rich native silver and cobalt ore specimen, but it could also be cut into numerous cabochons and used for jewelry or art work if desired (but I like it just as it is as a specimen!).
According to the MINDAT web site:  The Keeley and Frontier mines were two mines on the opposite ends of the same vein system that eventually connected underground. The Keeley Mine was discovered in 1907 and the Frontier mine in 1921.  The two mines finally connected on the Keeley 6th level in 1962 and were worked to a depth of 1,455 feet.  The mine(s) closed for good in 1965 after producing some 19,200,000 ounces of silver; 3,300,000 pounds of cobalt, 27,000 lbs. of nickel and 10,000 pounds of copper.
