This is a fascinating specimen and has a lot of really good micro crystals of Polybasite and Acanthite. But amongst the Quartz crystals is also some green Sphalerite, Chalcopyrite and Pyrite. There are two nice crystals of Calcite to 1.5cm and some of the Quartz is amethyst.

Large cabinet specimen of mostly crystallized Quartz matrix with choice hoppered habit Acanthite crystals. There are two main groups of Acanthite: one set has a large crystal measuring 2cm and the other in the set is about 1.5cm wide. The flip side has a large 1.1cm crystal and then there are several smaller, all of which are nicely crystallized.

Excellent specimen with several rare sulfosalts including Pyrargyrite (cherry red internal reflections) which is most of the matrix. The Argyrodite is in veins and is dull black and spongy. The rest of it is obscure and I can't really discern any of them with certainty. These include the Stephanite, Polybasite, Diaphorite, and Acanthite. The red you see in the photos I believe to be Sphalerite. The specimen was formerly in the Werner Paar collection. Werner is an expert in the mineralogy of sulfosalts, especially of this locality. Comes with Paar's personal label as seen in the prov. tab. Paar placed a catalog number on the specimen, which matches to label.

The specimen was originally labeled as "Argentite" by Hampson. Upon close inspection, I did not see any sign of Argentite/Acanthite, however I did observe plenty of waxy grey Chlorargyrite, a sure sign of Silver ore. This is an old time locality. Most likely from the Presidio Shaft, although the labels it as "Shafter Mine". During the period of 1927-1940, the district recorded a production of 11.8 million ounces of Silver and 7 million pounds of Lead from manto deposits in Permian limestones.
Acquired by Hampson in 1944.

Little 2-4mm greyish yellow, waxy Chlorargyrite crystals in a limonite basket. The Little Jonny mine is also known as the Ibex mine. The mine had 50 miles of underground workings with five shafts. The mine was first operated by J. J. "Leadville Jonny" Brown, who married "Unsinkable Mollie Brown" of the Titanic fame. Read more here.
