PGE Ore minerals available to purchase

First off, thank you to everyone who helped get these off our shelves so quickly in the last post- seeing how quickly we went through the first set of these, we will be continuing with unloading the extra mineral specimens left over from building our Layered Ultramafic Intrusion Geo-kits.

What's left:

We've got a few dozen specimens left of Palladium-Platinum bearing ores (with minor Rh, Ir, Ru, Os). The ores are in a few classes- Sulfidic Anorthosite/Troctolite, Sulfidic Serpentinite, Altered/Enriched An/Tr, and Altered/Enriched Sulfidic Serpentinite.

A Note on Grades/Certifications:

An important note; we have assay/xrf data for representative specimens for each category, but not every specimen with the group has been individually tested. Any specimen will come with a certificate/document of provenance which will reference the sample piece's grade.

Categorically, the ore grades are as follows:

Sulfidic Anorthosite/Troctolite (Type 1)

  • Representative reef material,
  • Grades are near exact to mine grades,
  • Used in the 60s to train NASA astronauts to identify potential PGE bearing deposits on the moon
  • Calling card for this mineralization

9-24ppm PGEs, with 3.6pd : 1pt

Sulfidic Serpentinite (Type 2)

  • Chromitite/Pyroxenite/Bronzitite base,
  • Higher grade representative of thicker areas of reef banding- "Jackpot" areas of the reef structure-
  • High grades, wild textures

12-35ppm PGEs, with 3.6pd : 1pt

Altered/Enriched Anorthosite/Troctolite // Altered/Enriched Sulfidic Serpentinite (Type 3)

  • Broken/travelled from original structure- alteration causes S-loss in these specimens, dramatically increasing PGE tenor in remaining sulfides.
  • Significantly higher grades than mine-ores.
  • Some of the highest grade PGE material that can be located, anywhere.
  • Truly unique specimens. Visually striking.

60-120ppm PGEs, some isolated extreme cases have shown 250-500ppm+

Specimen photos/pricing:

Serious inquires only please - these are research grade specimens that need a good home.

$50 minimum purchase to cover shipping.

Please DM or otherwise let me know if you are interested in a specific type or types of what we have available and I will provide photos, more details, etc. Larger pieces can be broken/modified as long as the entire piece is being purchased. The pieces vary greatly in size/weight and as a result are priced by gram.

Pricing:
Type 1 (Sulfidic An./Tr.): $6.50/g
Type 2 (Sulfidic Serpentinite): $8.50/g
Type 3 (Altered/Enriched): $15.00/g

These prices were verified against standards for high-quality PGE bearing reef material and then reduced to try and get these in the hands of serious collectors. These are great prices for genuine, unmistakable reef material/products.

The geo-kits we have put together using the rest of what we'd collected over the last several years were donated to universities. We intend to build more kits showcasing other unique geological settings in the future, and every dime we earn here will fund those donations as well.

Silicified Trace Fossil

Pulled this out of a backyard in The Woodlands, TX. Took me about 8 hours to get it out, along with some other pet wood pieces.

Would like to trade it for a sizeable chunk of petrified wood of a more colorful variety, some Texas plume agates I could eventually turn into cabs, or some picture jasper. I’m open to other materials for trading, just throw some pictures my way and I’ll give them a think.

All uncommon varieties! Mined by hand by yours truly 😉 and our buddy who owns the claims! These would make stunning jewelry (which would double prices!) or just a great addition to any collection! My DMs are always open even just for questions or a chat!

Disclaimer! Video is taken while stones are wet! Some are partially polished but most are raw, straight from the ground! They would look as they do wet with a good polish, these ARE NOT STABALIZED! And probably would not need to be! Fantastic quality!

Thanks for looking everyone! Much love to all the beautiful mothers in our wonderful crystal sub this Sunday! 💜🫶🏼

I’d like to add that nothing from my personal collection is for sale! Sorry guys! I’m too attached! 🫣🫠🫶🏼

What about this beauty

Price $179.99. You might think this price is steep, but when you look at the details. There's actually a discount in this listing. This is a special piece I decided to pair with a special Commerative Oppenheimer Stamp Sheet. The loose piece is actually discounted.
