Another Tool of The Trade: The Falcon MD 20 Gold Tracker

The Falcon MD 20 Gold Tracker is a good tool but it often produces uncertain results.

As depicted in this video, here’s how the detector should work. The detector sounds when going _toward_ gold, silver, copper and so on. Non-ferrous stuff. Which includes aluminum and, unfortunately, too often, strong iron targets. Those overwhelm the detector.

This pet wood shown probably contains iron oxides, giving a signal when the probe moves _away_from the target. In the field it is often difficult to tell which direction in which a signal is coming from.

Rocks need minerals in enough quantity to test reliably. The detector responds better when something singular is presented, not a mix of different, weak, conflicting materials. Never-the-less, even with a conflicting signal, one knows a rock is metalliferous.

I do like it for many reasons, though, particularly when pawing through ore samples at a rock shop. There may be a bucket of rocks advertised as silver ore, for example. If those rocks are from a named mine then I am interested. I’ll use the Falcon to test each rock for a signal. Finding none I pass.

If a mineral isn’t visible, I want that rock to at least respond to a detector. You’ll read nonsense about ore containing a mineral at a level above the crustal abundance. How do they know?

The Falcon is also good for testing rocks brought home from the field, ones not considered as metal bearing when collected. All finds should be eventually tested with UV lights, a Geiger counter, and a metal detector.

Burro Creek Campground, about ten miles or fewer from Wikieup, Arizona. This campground is base camp for rock clubs from as far as Utah. Agate is the main draw in the surrounding area, not at the camp itself. Potable water, first-come, first serve, the small group camp by reservation. $14 a night for the individual camp sites. Good pull throughs. Would advise smaller vehicles, ideal tent camping. No day use fee!

Creek is pretty but access is past narrowly spaced pipes, a nasty barbed wire fence encloses the entire campground. Good, clean water flowing right now. Great canyon setting, about 1,900 feet. Didn’t check cell coverage, I assume none. Anybody not enjoying rockhounding would still enjoy this campground.

View from the bridge over Agate Creek. Canyon invites exploring although get a BLM surface status management map of the area to show public land ownership.

The bridge abutments are  nicely done in Southwestern Art Deco style.

Don’t drive across the bridge with any large vehicle or a trailer in tow. Single lane dirt road beyond the bridge, I don’t know at what point you could turn around. Ask first. Logical place to turn around is the campground with its pull throughs in the Day Camp and regular campsite areas. Group camp looks tricky to turn around a large vehicle.

All 4X4 owners want a picture of their rig. It’s a thing.

Hi Tom,

I had said I would send a photo of one I was taking and a little story.

The Ludlockite is a piece I had only read about in a big “Worlds Best Minerals Book we have. It was a piece that a mineral dealer had seen on a porch of a guy in Namibia that sold specimens from the Tsumeb Mine, one of the most famous mines in the world.

The piece on the porch was being used to hold open the screen door. The dealer asked if it was for sale. The guy sold it to him and he sent it right off to his US business and it turned out to be a new mineral and that one chunk on the guy’s porch was all there was.

I had no idea when I saw one for sale for $10, the piece I took the photo of, that it had been discovered in the mine after that first piece was studied. They traced the associated minerals with it and found the place in the mine it had come from.

More was brought out but it was never very common. I got this one for so little and am very happy with it, as much for the story as the piece and as pretty as it is.

The other two I took photos of today too. The Ludjibaite is a rare species and I paid a bit more for the piece, $45 but it is very nice.

The last one of Ludlamite from Mexico we got many years ago and I paid only $10 for it as well and it is a well crystalized piece.

So, that is my recent material.

Now to post them on Mindat.org

Later,

More on the famous Tsumeb mine comes from this text at Mr. Kerry Day’s excellent website, he being the owner and proprietor of KAYGEEDEE MINERALS, a Canadian vendorship devoted to the mineral collecting hobby. He was an economic geologist/mineralogist/SEM-EDS operator for many years. “Selling off my vast collection of mineral specimens, gemstones and lapidary rough has become my retirement hobby.”

It’s a truly fascinating site that I recommend you visit immediately, for a sensational trip around the world while staying right at home. Thousands of great pictures.

TSUMEB MINERALS – Last updated April 12, 2019

The Tsumcorp polymetallic ore deposit was a near vertical ore pipe located near the town of Tsumeb, Namibia. A unique feature was three oxidation zones at various depths – the result of groundwater flow. The combination of oxidation(s) and unique chemistry created a vast suite of well crystallized minerals that are treasured by collectors worldwide. Unfortunately, mining ceased in the 1990s but neighboring ore pipes are now being explored/mined.

I had a happy time recently visiting the Keadys at their rock shop in Schurz, Nevada, a tiny town 34 miles north of Hawthorne Nevada. Only 90 miles south of Reno. Their store is at the intersection of South Highway 95 (Alternative) and US-95 itself. See the map below. Schurz is quite close to Walker Lake.

Chelsea and John Keady are miners, lapidary artists, rockhounds, and all-around good people.  Bryan Smalley affectionately refers to them as “The Kids.” These young people represent others like them who signal a bright future for the rock and gem trade.

 

They built their store themselves and everything that goes in it. They sell material they have either personally sourced or dug themselves. That includes Green Mist variscite and this Hellsfire agate. They carry many local rocks and gem material and fashion much of that into jewelry. John and Kelsea sell ready-made jewelry at the shop and they are always ready to do commission work.

 

A store highlight is a huge crystal they recently installed.

 

The Keady’s are now keeping the store open more often. Call first, though, to make sure they are there, and not off on one of their claims. If you can’t visit them at the shop, you might catch them at Quartzsite in January. They try to get there each year.

This store is a memorable stop on any drive from Las Vegas to Reno, or on any travel through central Nevada. Rockchuck is big on Facebook so check them out there if you want to keep up with all their latest happenings.

The store is right on the Highway. They’ve put up new roadsigns. And you can get fireworks nearby after you’ve loaded up with rocks.

I visited Goldfield, Nevada twice this past week, stopping in each time to check on Bryan Smalley’s Hidden Treasure Trading Company. Byran continues to do fine things in Goldfield.

Bryan runs one of the Southwest’s most interesting rock and gift shops. His rock shop complex encompasses three buildings; don’t leave until you look into all three. Bryan carries jewelry, much of it local, much made by himself, maps, books, cabs and slabs, and some rough.

Check out this wonderful jasper he is now cutting. He has hundreds of pounds more.

P.O. Box 512
Goldfield, NV 89013

Bryan is expert on local rockhounding and accomplished at lapidary. He does knapping and can talk authoritatively on making flintlock strikers from locally collected chalcedony. Need advice on polishing? He has it.

Ask locals where Bryan is if you can’t find him. Try the Dinky Diner. Goldfield citizens won’t mind you asking, in fact, they are very friendly. You should give a wave to people as you drive by. Don’t get discouraged if you can’t find his shops at first. Drive around. You’ll enjoy your time.

Bryan has a minimal web presence but he is busy with real life, finding rocks, cutting rocks, and making jewelry. When investigating the nearby Gemfield Gem claims, make plans to see him. Well worth the effort.

Yes, he made that door himself. And the shop.

Another Update on The Gemfield Gem Claims in Goldfield, Nevada

Sharon Artlip has been in touch. She and her sister Nadiah Beekum own the Gemfield Gem claims in Goldfield, Nevada.

I’ve written quite a bit about the claims at this site and also in the May, 2016 issue of Rock&Gem Magazine. Another name for the claims now seems to be “The Rainbow Chalcedony Claims.”

Sharon writes that, “It has been a wonderful couple of years.  We are still having fun at Gemfield and always trying to improve it.  If you would like I will send you the current brochure.”

Rocks go for a dollar a pound. Everything is on the honor system. Register at one of several Goldfield businesses before going to the claim. Easy dirt road but not recommended for large RVs.

Wild burro country. Antelope, too.

Here’s a link below to the current brochure in .pdf:

Prospecting Thoughts While Traveling in Southern Nye County, Nevada

The fun stuff: Instagram — tgfarley

I went driving today to my club’s claims in the Johnnie Mining District in the hills outside Pahrump, Nevada. I never made it.

Instead, while driving HWY 160 west toward Pahrump, I thought about all the BLM land to the south of that road that may have not been recently prospected or rock hounded. The reason? A sturdy and nasty barbed wire highway fence with few breaks in it, only one faint road into the area in several miles, and few good pullouts to park. That’s enough to deter most prospectors even if the land is open and the ground unclaimed.

Compare that to Crystal Road, which strikes north from HWY 160 about four miles from I-95. No highway fence on either side. Fairly soon after leaving HWY 160, 15 to 20 large piles of dirt appear somewhat randomly over a mile or so to the east of Crystal Road as one travels to Crystal. Backhoe produced. Someone searching for gold.

I looked over some of these piles and their trenches. Must have been fairly old workings as BLM now requires a plan and  permit to operate heavy machinery on a claim. Unless some locals went rouge one day, possibly sampling on a large scale.

While I didn’t see any claim markers I felt uneasy about investigating further. Normally I would break out my metal detector or a bucket to take some rock and gravel. The more rural you get, however, the more testy locals become. I did have my laptop and there was cell coverage. I could have pulled up LandMatters to see if the area was under claim. But all map drawing websites are painfully slow with an average cell connection.

When I got home I researched the area a little. That ground was indeed unclaimed, with the only a large set of claims around the rough settlement of Crystal. If I go again to sample I will print out some maps first. In thinly populated areas, any truck parked on the side of the road gets attention. A person with a metal detector, a pick, and some five gallon buckets may be the highlight of the day for a nearby resident. Word will get out fast. If you prospect, you must handle the attention it attracts.

When I was last at my club’s claims, a fellow member pointed out the view east to I-95. “There’s gold all the way to the highway.” Hmm. Maybe washed from the hills. But in paying amounts? Some people think so, judging by those exploratory diggings and the fact there are so many claims around Crystal.

With temperatures now climbing, and my book deadline getting closer, I won’t be going back soon. But I will keep wondering about the area. And wondering what lies on the other side of HWY 160, the same looking ground but prospecting seemingly defeated by a wire fence. There is much to explore.

Okay, I will admit it. I got under that fence to sample a wash. Brought the gravel home. I don’t hope for gold when sampling blind, I look for black sand. Hardly any. But I didn’t get out my Whites GMT, which has a black sand tracking feature. It produces a  numerical readout to close in on areas with a greater likelihood of paystreaks. It’s far easier to search a gravel bar or a desert wash than with any other method.  But I ramble.

 

 

 

 

Mineral Mystery Musings by Rolf Luetcke

Hi Tom,

There are things out there that certainly are mysteries. I have quite a few in my past that were interesting.

One was a fellow on Mindat.org who found me by way of that site. He was from Tucson and messaged me about something he found deep in the mountains of SE Arizona. He was not a mineral guy but found a vein of quartz that had a silver material all over it and he was convinced it was a new metallic deposit he had discovered while bird watching. He sent me a piece and as soon as I saw it I knew it was not a natural material. I emailed him back and said I thought it was something man made. He just couldn’t believe it since it was “in the middle of nowhere” as he said. I told him to take it to the University of Arizona Mineral Museum. I told him I thought it was some kind of stuff painted on the rocks since it was only on the outside and didn’t go into the quartz where he broke it.

He took it to the University and they were also intrigued and said they would test it. He wrote me back a week later and said he got the results and it was aluminum paint. He was certain he had found a new mineral deposit but someone had actually painted some rocks in the middle of nowhere.

Another one was a fellow we met at the shop had been in the same area of old mines and he was a mineral collector, although not a very knowledgeable one. He posted on Mindat that he thought he found Millerite in the Patagonia area. He had not contacted me until after he had posted the material. I told him that was not possible because there was no chemistry in S Arizona to support that. Another friend had been with him and he gave me a piece of the same ore and as soon as I looked under the microscope I saw it was Stibnite, a mineral that was supported by the chemistry. They did find that Stibnite in an area Mindat did not list for that mineral’s locality, so that information has been added to Mindat. It was not the Millerite he hoped it was.

Dreams die hard. Mary told me many years ago when I found a new thing at a local mine and thought it might be some rare species, she said it is probably a much more common species but in a form I had not seen. She is usually right in pretty much all these cases and I learned a valuable lesson. I passed that onto the friend who gave me the Stibnite and he now thinks that his material was probably a more common mineral.

Got a bunch of those stories over nearly 48 years of mineral collecting.  Having worked with minerals now for so long I have gotten pretty good at identification but I do need to use a microscope to be sure.

Will be interesting to figure out what that “weird stuff” turns out to be you found in that field. Seems rock related and not necessarily mineral related and that is often harder to get figured out than a mineral.

Have a great day.

Minerals Unlimited in Ridgecrest, California

What do the best bars and rock shops have in common? They all have a gravel parking lot. Whenever you hear gravel underneath your wheels in the desert, you know you’re going to have a great time. Don’t fear for your vehicle though, as you only have to go fifty feet off pavement. And that distance will take you very, very far into a wonderful rock, mineral, and jewelry world.

 

Wendi “Ace” Elkins, singlehandedly owns and runs Minerals Unlimited in Ridgecrest, California. It sits next to a Salvation Army thrift shop and is one the finest rock and mineral stores in the Southwest. Its been operating for seventy years, always family owned. Minerals are neatly arranged in alphabetical order in dozens and dozens of wooden drawers, all of them inviting you to tour our rocky planet without leaving Ridgecrest.


A tremendous rock yard exists outside, with rough of all kinds and descriptions.

Working under the moniker of “Jewelry by “Ace,” Wendi fashions jewelry as a creative outlet for herself and to show off the many rocks and minerals her store offers. This description and picture is from her website:


“This lovely slab of native silver in calcite was mined from the Alhambra Mine, in Grant County, New Mexico. I used sterling silver wire to compliment the design. I had to let this one “talk” to me for several months, to make a complimentary wrap, but I think it was worth the wait.”

Wendi and I commiserated over static photographs being unable to convey the sparkle of jewelry and of rocks in general. You have to see in your hands the play of light from her designs  to see how special they are. Another reason to go in person.

You never know what you’re going to find at this store. I pulled out a drawer at random and it produced a stunning display of violet fluorite with cleaved octahedron shapes.

Stop in Ridgecrest whenever you’re in Southern California or traveling to nearby Death Valley. You may want one thing but you’ll carry out many more. She sells online, too, so check her website or give her a call. Make sure to phone before visiting in case she is out of town at a rock show.

And if you want to buy an entire rock shop, not just a rock, talk to Wendi. Running the store has become tiring and Wendi is considering serious offers on her business. She has worked at Minerals Unlimited since she was eight, on the payroll from 16, the owner since 2003. During this decision making time, however, the store remains fully open and operating and there is no thought of closing. There is a tremendous inventory here,  built up over decades with a great deal of material no longer available and unique to this shop. If you buy the store, you’ll have a head start on running it because everything is labeled!

Ridgecrest is centrally located to the historic mining districts around Randsburg to the south and Ballarat to the east. Nearby Sequoia National Forest to the west offers great rockhounding, especially along Highway 178, and the eastern side of the Sierra Nevada mountain range is revealed by heading north on U.S. Route 395. Starting at Ridgecrest itself, guided tours organized by the Maturango Museum go out in spring and fall to visit Little Petroglyph Canyon. There, rock art images by the thousands were etched into canyon walls and boulders by native people long ago. Plan well ahead for this bucket list tour.

Ridgecrest is a relatively small, quiet town, supported economically in large part by the Naval Air Station called China Lake. Its role is ongoing and vital, its decommissioning practically unthinkable, lending stability to this tranquil desert community. If you are near base at twilight, you may hear the lilting sound of “Retreat” over loudspeakers. This marks the lowering of the flag for the day. Cars on base stop and park for this short interlude. People get out of their cars and face the flag or the direction of the music.

A unique shop. A unique town.

The Drill

The Drill. Checking my recent road trip finds with my Geiger counter, handheld metal detector, and my two UV lamps. Just to see if anything else is going on besides the reasons I originally picked them up.

One piece under shortwave fluoresces a nice green. May have found some common opal. This was on my last stop, when I pulled off the highway on a whim to walk the desert floor. At first I thought it was an agate because one side displays a translucent quality along with a wavy banding. When I got home, though, with my tools, I remembered I had seen something like it.

That piece matches the color, luster and the fluorescence of Arizona opal I recently got in trade from rock and mineral dealer Rolf Luetcke. Although simply white, the rock comes alive under shortwave UV. Not the intensity or brightness of Rolf’s piece, that material is top-notch, but the exact same color under the lamp.

Update: Not opal. A steel nail doesn’t scratch it, but a nail scratches the opal Rolf supplied. The piece must be chalcedony or agate, or whatever you want to call cryptocrystalline quartz. Hmm. What are the odds that I would find something that looks exactly like something else and fluoresces just like it as well. At least I know a place to search for fluorescent agates. The agates I have don’t fluoresce, certainly nothing green.
