Thanks for moving this as a new topic. Can one of the Admin make a New Mexico Collecting thread and include the Macy mine in it? I am planning on writing and showing photographs for many more New Mexico localities, and this topic should be part of a larger group of stories/photos.

A few more photos from the first trip I took with my father in June 2016. The vanadinite photo is on my collection page, but it needs to be part of this topic as the specimen is most likely the best vanadinite (variety arsenatian) that has been found from the Macy mine.

Thanks for sharing these photos, Philip! Great vanadinites. I've collected there, with Ray DeMark, but, gosh, it's probably been over 35 years ago.

One of New Mexico's most renowned localities is the Mina Tiro Estrella claim located near Ruidoso. In the late 1970's the famous southwestern field collector, Dick Jones, learned about a smoky quartz vein at the foot of the Capitan Mountains and decided to investigate. He dug there for several months and eventually found a series of pockets that produced superb dark smoky quartz Japan-law twins on a quartz/feldspar matrix. These specimens quickly gained notoriety, both good and bad. The good: the specimens Dick collected made a huge impact on the collecting community, and collectors quickly snapped them up when he set up "tables" of the material at the Tucson show. The bad: nobody who has worked the claim since has found even a fraction of the quantity of dark smoky quartz that Dick had, and there are credible reports that he sent them to a University of Arizona lab to be irradiated and turn the quartz a dark smoky color. Once word of the find got out, Dick had many problems with high-grading , and he eventually let the claim lapse. The claim lay mostly dormant for the next several decades, although several people owned the mineral rights during that time.

I had always dreamed of collecting here, but I had never been able with my father when I was growing up. A little over five years ago, I was finally able to track down the exact location of the claim, although I was told by New Mexico collectors that the area was mostly worked out by the previous owners. However, I was determined to collect there since it was a childhood dream. The first trip took me several hours to locate the pit that had been dug by previous workers because everything had been overgrown by plants due to a fire in the early 2000's. Near the end of the day I did manage to find the place, and I immediately located a good spot along the side of the 5 meter by 15 meter pit. Within two hours I had dug several nice twins (up to 3 cm), and I was hooked! I have been working the Mina Tiro Estrella locality ever since, of which I am now a part owner.

Quartz from the claim is generally light-to-medium smoky, and untwinned crystals, to 9 cm, are often the Tessin habit. One unique aspect about the quartz is that a large percentage of crystals form contact Japan-law twins. The twins are highly striated on the prism faces perpendicular to the twinning plane. Twins range in size from less than a centimeter to over 12 cm wide. They also form "heart" or "butterfly" twins, "rabbit-ear" twins and elongated vertical twins where the re-entrant angle is nearly imperceptible. I have even managed to find an extremely rare Reichenstein-Greiserntal twin!

Phil,
Thank you for your report along with the excellent photos. It's a treat to actually see the fabled quartz locality and extracted treasures. Your picture of Sierra Blanca reminds me of the times I've looked from there toward the El Capitan site, wondering what ever happened to it. Friends have tried finding the location without success, so I wish you continued success in collecting.

Here are a few more photos from Mina Tiro Estrella. This brings everything up to date for the claim. I will post more photos as I continue to dig for twinned smoky quartz!

I forgot to include this little story for the "Best twin just from pocket" photo.


My best find of the entire time I've been digging on the claim has a good story. I had been digging for two days and had found a few good specimens (see Tessin Japan-law twin). As I dug deeper in the vein, I opened up a huge pocket for the locality. It was 25 cm across by 70 cm deep and had nothing in it! This is very unusual because most pockets have many, if not hundreds of, small quartz crystals in them. I only found one partial twin in the entire pocket. After two frustrating hours of digging nothing but pocket clay, I eventually hit a piece of quartz in the very bottom of the pocket with my digging tool. I didn't pay much attention to it until the next bit of clay removed revealed a large crystal. I excitedly uncovered the rest of the crystal and then the other half of the twin! As I pulled the twin from the clay I noticed an indentation in the ceiling of the pocket that looked like matrix. Sure enough, I extracted the matrix and matched the rock to the twin. The resulting specimen is the best twin I have found on the claim and one of the best twins to have ever been found there!

Philip, although the ground may be wet, have you tried to stabilize the clay "matrix" with thin Star Bond like the paleios do for their bones? Might result in more specimens on "matrix."

Wow Philip, how blessed you are to have a dad that digs with you. Mine died many years ago. Field trips are so exciting, especially when one sees where the specimens on the shelves originated from from. Thank you for sharing your exciting adventures with us.

So good article to read through! Waiting for your next update!
