I was actually over on the Sawtooth side, but most people recognize the Rye Patch. I consider myself a fairly rugged guy, but N NV in July is no place to be without some decent shelter from the afternoon sun and heat. A 10 X 10 Walmart quick shade seems to provide shade, but focus the radiant heat somehow making it hotter under the shade, if that makes sense. The afternoon breezes are hot and dry leaving my only thoughts to cold drinks. Cold beer was my last choice, Gatorade and water were the only solutions. I endured 2 days and found 1 tiny nugget with the Nox 800.
I rode my Rokon and explored way up an old "ghost road" on the afternoon of the first day. With field glasses I saw a couple canyons that had exposed bedrock and I aimed to hike them the next morning while it was cool. N NV climate is a funny thing, I woke up to 61 degrees, but temps would climb to 90 by 11AM. As I was gathering my gear, I had one of those nagging premonitions. I suspect we have them all the time, but only remember the ones that come true. Nevertheless, I packed extra water and my Garmin Satellite Communication device. I was merrily riding up the ghost road enjoying the refreshing morning air when, bang. I felt the Rokon torque converter explode into the protective fiberglass shield. Fortunately, I was only half way to my destination. I carry tools and some spare parts, but no amount of duct tape was going to fix this problem. I pulled all the unnecessary stuff out of my pack and started walking back to my truck. It was all downhill, with a decent breeze so I made good time before the unbearable heat set in. I packed my truck and strapped down all my gear for some tricky 4 wheeling to get back up there to the Rokon. Turns out to be 4.7 rugged miles. I loaded the Rokon and decided to head for home in sunny Yuma where it was only 116 degrees.
It could have been worse however; the Garmin device, in addition to the emergency SOS, has a feature where you can send free preselected messages to your family and friends. At the end of the message the device stamps your GPS coordinates so they know where you are. Since I do so much prospecting alone, I make this compromise so people worry less about me. For $30.00 a month service fee, it's cheap insurance and my family worry less. So, every night I send a preselected message of "Alive and Well" and they can plot my last location if something happens to me. Staying home where it's safe is not an option in my world.
I spent several weeks in early July, panning and sluicing on the N. Fork of the American River. I've been going to the same 10 mile section of the river for over 20 yrs. That part of the river is designated Wild & Scenic, so no motorized equipment and no claims. It's one of the few places in CA gold country you can access a free flowing river without stepping on someone's gold claim. Access is not easy, although there a a number of trails up and down the river. They're all rugged, often steep and always overgrown with poison oak. I have often encountered "locals" who at various times attempt to eke out an existence by panning and sluicing the river. Generally friendly and sometimes willing to share local knowledge of the gold. When I meet them I make a point to brew up a big pot of spaghetti and feed all comers. Many years ago, I met a guy my age driving a new Jeep Cherokee. He was socially awkward, but I learned he was a software engineer from the Silicon Valley and had taken up gold prospecting on weekends. He was not very successful, so my 6 yr old son and I invited him to come dig in a hole we had started. He sluiced a few buckets and declared that was more gold than he had ever found. Skip ahead 10 years, I found him living in a tent on the banks of the river having spent 2 years pursuing the golden dream. He was eking out an existence and seemed to be perfectly happy. Imagine a 6 mile hike uphill, just to reach a paved road, hope for a ride to town to get supplies then repeat the process back down. Supplies are limited to what you can afford and carry on your back. The local mining supply store pays 80 percent of spot, for good clean gold. This guy still had the math and engineering brain so he could tell me exactly how much he was earning per hr, although he did not factor that it was in fact a 24 hr a day job, living on the river.
Every now and then "flatlanders" discover the place and bring down a bunch of gear intending to strike it rich. They are soon disillusioned and I find their gear stashed in the woods. I've seen one sleeping bag stashed in the same spot for over 4 years, untouched. Buckets and digging tools get carried away by spring floods and I find them littered on gravel bars.
There is an old mining road ,overgrown, heavily rutted, washed out and frequently blocked by blown down timber. It currently takes me about an hr to travel just over 3 miles down that road crawling in 4 wheel drive low locked in 1st gear. At one time you could drive to within 100 yds of the river. There was a fabulous camping spot under a massive oak, with a spring nearby. In their infinite wisdom, the BLM blocked the road about 1.5 miles from the old camping spot. They brought in some heavy equipment and dug tank traps to block all future traffic down the road. For many seasons I hiked the rest of the way down on a variety of trails. A few yrs ago, my son, then strapping teenager and I started hacking an ATV trail around the tank traps. We spent a few hrs a day for over a week cutting a new trail. It's passable by ATV to this day, but you really have to know the danger spots or slide right down the hill. I've winched my own ATV up that zone many times.
More to come in Part II.....

Abandoned Trails in Silver Country
Silver country represents a small part of a vast, heavily forested wilderness perched on the sprawling Precambrian Shield here in northeastern Ontario. Away from the small towns and villages, and widely scattered farms and rural homesteads, there exists a largely uninterrupted way of life in the more remote areas. There are uncounted miles of lonely country backroads, overgrown tracks leading to abandoned mining camps, innumerable rough timber lanes, and a virtually infinite tangle of winding trails that reach deeply into the distant forests.
Nothing in my experience has been so completely companionable as the soft forest whisperings and the beckoning solitude that reigns over this ruggedly beautiful country. This is where my carefree days of autumn prospecting have been agreeably spent for many years. We returned again this year to unbounded, satisfying autumn days of kicking rocks, exploring and detector-prospecting adventures, followed by evenings spent evaluating silver ores while savoring hot coffee over blazing campfires.
Irrespective of silver recoveries, the flaming autumn colors of the boreal forest are the real treasure of the season. They persist for only a few short weeks, reluctantly yielding to the autumnal yellows of the tamarack, birch, and aspen in sharp contrast to the deep conifer greens. Scenery as depicted below accentuates your enthusiasm to get into the field, and pretty much ensures that an autumn prospecting trip to silver country is a memorable experience.
Unprecedented, persistently wet conditions eliminated any potential for a banner season, but nonetheless we did manage to find considerable worthwhile silver. In addition to an assortment of rich silver and associated minerals, my friend and occasional partner Sheldon Ward recovered a large, very high conductive native silver ore that we’ll take a closer look at shortly. Most of my quality silver finds were fairly small, although a specimen grade silver ore at five pounds was found during the final week of the trip, and frankly I felt very fortunate to get it. Larger material was recovered, for example a 24-pound highgrade silver ore from the same area, but these invariably were mixed ores co-dominated by cobalt and various arsenides, most notably niccolite as illustrated below.
On a more positive note, we both found plentiful small silver generally ranging between one-half and ten ounces that added real weight to the orebag over the season’s duration. It is much easier to find small but rich, high character silver than is the case with larger material. Even so, specimen grade detectable silver in any size range is becoming increasingly difficult to find at many of the obvious, readily accessible sites nowadays.
The photo below is a pretty fair representation of the overall quality, although anything below a half-oz was excluded from this shot… such are not terribly photogenic beside larger samples. Some rich ‘nuggety’ ores were HCl acid-bathed to free the silver from carbonate rock, and all samples were subjected to a rotary tool circular wire brush to remove surface residues, followed by a dish detergent wash and rinse.
By way of a brief background explanation to readers unfamiliar with this prospecting application, we search for more valuable coin-size and larger pieces of silver. Natural native silver target ID is determined by physical and chemical factors such as silver purity, types of mineral inclusions, structure (for example, dendritic, plate, disseminate or particulate, sponge, nuggety or massive), size, shape, and the profile presented to the coil. Virtually all natural silver from this area will target ID from low foil up to a maximum of silver dime range. Only infrequently over the years have we found isolated, rare examples of our naturally occurring silver exceeding that range.
The specimen depicted below is a commonplace example of silver typically recovered here. It isn’t terribly large or particularly handsome, but it is mostly comprised of native silver by weight. Its target ID is a bit elevated from the usual, but consider that even small changes to some of the more influential factors listed above can significantly alter target ID. I tend to pay minimal attention to it when evaluating samples.
It was detected adjacent to an abandoned mining track that leads directly to a former mill site at the mining camp scene depicted above. No treatment required other than a leather glove rubdown followed by a soapy wash and rinse, in fact it looked quite presentable fresh out of the dirt. The darker material you see is heavily tarnished native silver that I intend to leave undisturbed.
Ground conditions also play an important role in determining target ID, and refer to factors such as the strength of non-conductive magnetic susceptible iron minerals present, ground moisture content, proximity of adjacent targets, and disturbed ground. These factors sometimes contribute to good silver at depth producing a VLF target ID within the iron range.
Probably the best photo example available to me is a specimen found a few years back at good depth in tough magnetic susceptible diabase. It produced a predominantly iron target ID on the Fisher F75. It was detected in a fairly low trash area, the signal was suspect, and it was checked with the groundgrab feature. In this instance, there was no ground phase reduction to more conductive values as would be anticipated over rusty iron or a positive hotrock, and so the target was dug.
The general rule of thumb over questionable weaker signals, regardless of groundgrab results, is to remove some material to acquire a stronger signal and target ID readout before making a decision to continue digging in our difficult, hard-packed rocky substrates, or to move on. If there is the least doubt, we dig the target to learn what actually produced the signal.
The specimen depicted below was found by eyesight while hiking along an old abandoned rail track. In the field our rock samples seem more attractive or valuable than they do once we return to camp, where we tend to view them far more critically. If they don’t look to have good specimen grade potential, my samples are either abandoned in an obvious place for others to find, or given away to visitors back at camp. But that’s just me, most hobbyists are more resourceful with unwanted samples, they’re refined by some, subjected to treatments, or slabbed, and ultimately sold. In any case, this rock didn’t terribly impress me and was placed with other discards on the picnic table. But nobody other than my wife seemed much interested in it, and that is how it came to be included here.
In its original condition, it could only be described as nondescript, with very little showing on the surface prior to treatment. It did produce a broad solid PI signal, despite that the few surface indicators were non-conductive dark ruby silver pyrargyrite and to a much lesser extent what I suspect is the black silver sulfosalt stephanite. To see more, it was acid-washed to expose silver and associated minerals, cleaned-up with a rotary tool, followed by a dish detergent bath and clean water rinse.
Both these minerals produce a good luster that makes them a bit more difficult to distinguish from native silver in a photo. But in reality it is easy to see the differences and do some simple tests to confirm if necessary. The acid treatment revealed that the sample does have a good showing of dendritic native silver, a timely reminder that metal detectors see what we initially can’t see inside rocks.
Abandoned Trails, Minesite Tracks and Roadbeds…
Abandoned, frequently overgrown trails, mining tracks, and roadbeds provide convenient routes to prime detecting sites that otherwise would be much more difficult to access. But the important thing is that most such routes were built with discarded mine tailings to considerable depth, and contain good silver more frequently than you might think possible. Some snake through the bush to more remote areas, but the vast majority of these now abandoned routes were built to service existing minesites at the time. They were used to transport discarded rock to the tailing disposal areas, and silver ores to storage buildings and to mill sites, and generally to service other mining camp requirements.
We know from research and experience that silver was misgraded, inadvertently misplaced, or lost directly from spills to eventually reside on, within, or alongside these now abandoned trails and roadbeds. These mine tailings… frequently containing rich silver… were also used to build storage beds, minesite entrances, loading ramps, and as noted… routes to facilitate waste rock transport. All these offer excellent, obvious prospects to search with a suitable metal detector.
The nugget below, with several other pieces, was found in the tailings adjacent to the abandoned track in the photo above. Some good weather following a horrendous week of persistent heavy rainfalls prompted me to head out late one afternoon for some casual detecting. I had sampled those tailings earlier in the season but nothing by way of thorough searching. And while the silver was generally small, it had been surprisingly good quality. So I was looking forward to a few relaxing hours of detecting… nothing ambitious that late in the day… just happy to get out of camp.
That particular spot formerly housed silver storage beds, and was now replete with large rusty nails. I should have used a VLF unit, as things would have gone much more quickly. VLF motion all-metal detection depth in that moderate ferromagnetic substrate would pretty well match Infinium equipped with the 8” mono, with the further advantage of target ID and groundgrab features to assist with signal evaluation. If conductive pyrrhotite hotrocks had also been present, I would have switched over to my F75 or MXT to take advantage of target ID.
But I stayed with the Infinium primarily because I enjoy using it. By comparison it is slow going, but that isn’t such a bad thing over potentially good ground. It silences what can be described as VLF ground noise, in addition to sizable non-conductive mafic hotrocks in this area. It also has some limited high conductive iron handling capability, for example elongated iron such as drillrods or rail spikes at depth that VLF units using iron discrimination modes misidentify with perfectly good signals and non-ferrous target ID readouts. More information on this subject can be found at… http://forum.treasurenet.com/index.php/topic,384975.0.html http://forum.treasurenet.com/index.php/topic,385640.0.html
Nearly all the signals proved to be nails, plus one drillrod with a perpendicular profile to the coil. The silver below produced a low-high signal in zero discrimination and a good high-low signal in reverse discrimination (maximum available pulse delay setting) at maybe eight to ten inches depth. The exposed silver was unusually tarnished and the remainder partially embedded in carbonate rock. It was acid-bathed to free the silver, cleaned with a rotary tool silicon carbide bit and circular wire brush, followed by a detergent wash and rinse.
While searching one such abandoned route with his Fisher F75 equipped with the stock 11” DD elliptical coil, Sheldon Ward found a large highgrade silver ore comprised of a thick calcite vein containing massive dendritic native silver. The vein material weighs about 25 lbs, and was attached to a mafic host rock. It generated a moderate but broad signal from several feet depth, requiring an hour of hard pick and shovel work to recover it. It possesses an unusually elevated target ID in the silver quarter range. After 30+ years searching this area recovering numerous silver ores and nuggets, I've seen only a small handful of silver produce a similar target ID.
On site we obviously have the benefit of closely examining the vein material, but it’s more difficult for readers to evaluate the silver based on photos only. Outdoor photos do tend to make native silver look much like grey rock, and unfortunately this one is smudged with dirt. I’ve added an indoor photo from Sheldon that displays the vein material after it was separated from the host rock and cleaned.
Sheldon if you happen to be reading along here, congratulations on your many superb silver and associated mineral recoveries over the past year. Nothing that your dedication and persistence achieves in the years to come will ever surprise me. WTG!!!
Persistence Pays Dividends…
Let’s wrap things up with a tale about the rock sample below. It was recovered at the edge of a tangled overgrown trail near a former millsite just a few years ago. Its recovery exemplifies that the more you work towards your objective of finding silver or gold, the more likely your probability of success will correspondingly improve.
I’d been searching that particular area for two days without meaningful results while evaluating a newly purchased Garrett Infinium for this application. The second day had again been filled with digging hard-packed rocky substrates for iron junk, worthless or otherwise unwanted arsenides, and plenty of conductive pyrrhotite hotrocks. As the sun was reaching for the western horizon, I decided to make one final effort before heading elsewhere the following day.
Methodically working along the old track towards the mill, lots of old diggings were plainly visible. But previous hunters had ignored an area with a scattering of large, flat rusty iron pieces and other miscellaneous modern trash. I moved quickly to clear it away, because daylight was fading fast beneath the dense forest canopy. My Infinium soon produced a surprisingly strong high-low signal that practically vanished in reverse discrimination… a promising indication of naturally occurring ores. I dug down a foot before my Propointer could locate the signal.
Probability says that it could have been any number of possible targets altogether more likely than good silver. But fickle Lady Luck was more kindly disposed towards me that evening. The rich, finely dendritic piece depicted below was in my gloved hands just as twilight was stealing across that lonely abandoned trail in remote silver country.
A Final Word…
A special mention to my friend Dr. Jim Eckert. I hadn’t seen much of Jim recently, but happened across his trail late one overcast afternoon in the outback. I was about to hike into a site when this fellow came flying down the trail on a motorbike, and despite the riding helmet I recognized him. We had a good long chat about this and that…
Later in the season, one bright sunny afternoon at the site of my short-lived testhole diggings, Jim stopped around to show me a recent specimen find comprised of native silver and crystalline stephanite. We talked mineralogy and other interests many hours until finally the sun was going down. These were highlights of the trip, and I want to say how much I enjoyed and appreciated having that companionable time together.
Thanks to everyone for dropping by. We hope that you enjoy presentations about naturally occurring native silver, particularly since it is different from what many rockhunters normally encounter in their areas. All the very best with your prospecting adventures… perhaps one day it will be our good luck to meet you in the field…………………… Jim.

Detector Prospector “Rocks, Minerals & Gems”
By Steve Herschbach
I have used many metal detectors over the years, and right now I have to say that the new Makro Racer 2 has perhaps the easiest to understand, best laid out, most practical display and menu system I have ever seen in a top end detector. Now, you can sure say you hunt by ear and do not need a screen and I get that, but if we are going to put a screen on a detector, then let's do it right.
Simple detectors with few functions are easy to make screens for - there is not much you need. But even then just the basics are often wrong. Machines that feature target id numbers, what is the thing you will most look at on screen? The target id numbers! Yet these are often way too small or off to the side as if an afterthought.
The Makro Racer 2 id numbers are huge, much larger than on the original Racer and Gold Racer, which are already good sized. The number 88 display in the diagram above is fully 1.5" x 1.5" in size in real life. Other machines have some pretty big numbers but I think this sets a record as I can't think of any machine with larger id numbers on screen though some are close.
Makro Racer 2 LCD display and controls
Makro Racer 2 screen layout
Makro Racer 2 screen and control descriptions
The number can be the ground balance number, target id, or depth reading. You get a text display just above the number confirming which it is. Below the numbers are three zone references, Fe, Gold/Non-FE, and Non-Fe, that are used to set tone breaks and audio for the three main zones or bins as they are sometimes called.
Another basic feature lacking on a lot of machines - the meter backlight. With the Racer 2 you get off, intermittent, or full time backlighting, and it includes the translucent red control buttons. The control ranges between 0-5 and C1-C5. At 0 level, the keypad and display backlight are off. When set between 1-5, they light up only for a short period of time when a target is detected or while navigating the menu and then it goes off. At C1-C5 levels, the keypad and display will light up constantly. I do not know of anyone doing a better backlight.
The right side of the meter is informational - ground phase (ground balance number), mineral % (ground magnetite content), coil warning notices, and a six segment battery meter.
Across the top below the 0 - 99 reference sticker, is a series of 50 "bullets" each of which covers 2 target id numbers. Open bullets (which appear gray in the diagram but are invisible in real life - see top photo) indicate accepted target id numbers. Blacked out segments show what discrimination and notch setting you have programmed in a single quick glance. When a target is detected, the big number on the display will be mirrored by one or more of the bullets flashing dark.
The four control buttons are simple as can be - up and down takes you through the left hand menu area. Right or left lets you set each function selected by going up and down. The menu is basically the entire feature list just laid out right there for you to see. You want to know what this machine can do, just look at the screen. Most other machines you have no clue without reading the owners manual or at least pushing buttons to see what functions appear.
Some settings like the backlight are system wide for all modes. All other settings like Gain are independent in each mode, and can be saved independently in each mode. This means you can play neat tricks like setting up a couple modes with dramatically different settings and then flip back and forth easily between two modes for target checking.
You even get to decide what mode is the default start up mode. The Racer 2 starts up in the last mode where the save function was performed. If you always want to start in Beach mode, just modify and save something in Beach mode. Next time you start the detector, you will be in Beach mode.
It is simple. It makes sense. No cryptic abbreviations or acronyms. No sub menus. It is, in metal detector terms, a work of art. Whoever designed this should sign it so I can frame it and hang it on my wall.
The following is a compilation from my Rutus testing and useage.
Very long, but anyone wanting some info, this here may help folks.
Btw to my knowledge currently no dealers for this detector line in USA.
They can be purchased from abroad.
The Rutus Alter 71 may not be very well known, but make no mistake a very good detector for what they cost.
There is some comparison info too with other detector models.
Overall weight and feel of unit is IMO nice,,not heavy feeling.
Btw. Concentric measures 8.125" outside to outside diameter.
Supposed 11" dd measures 11".
I even with little time I have run this unit,,this unit designed to be a Deus killer for the $$$. Question is, is it??
Using concentric coil user likely not to dig steel bottle caps, hodograph paints a good pic of junk target,,a backwards C in the meter. Haven't tried DD coil yet to see what happens here.
Depth is dependent on mask setting,,meaning for fringe depth the lower the better.
Interesting how they gave a user options here to have their targets ID in the meter.
Three choices real-- ID is directly reflective of frequency run and conductivity of target.
Then 2 other options,,you can select either 6khz or 12khz for target ID normalization.
So with saying all this here is some data using each of the above selections for target ID.
I should say the Rutus uses a different scale when comparing to most other detectors-- 0-120.
Real ID option selected and frequency selected on detector at max 18.4khz
Normalized setting of 6khz selected,,detector still set to 18.4khz
Normalized setting of 12kh selected,,detector still set to 18.4khz
Frequency changed on detector to 7khz,,real ID option selected
Frequency still at 7khz,,6khz normalization selected
Frequency still at 7khz,,12 khz normalization selected
Preliminary test using 3D test with coin and nails,,detector seems above average with what I see,,,Deus like results,,,not giving either detector yet no advantage,,with time maybe.
Audio,,,Rutus audio not as smooth as Xp Deus,,not as blendy sounding,,leans more toward what I call beeps. This is not meant to say Rutus audio is terrible or anything.
I am still trying to nail down how I want my tones set up using the user programs,,,not there yet.
Does take time though,,user must select each number TID wise and singularly adjust,,,no blocking of groups of tones to adjust.
I do reserve the right here to correct anything I say about this detector in the future.
From what I can tell right now,,Rutus will retain settings when turned off.
Turn back on,,user will need to ground balance though.
Also what ever you have selected,,this is where the cursor will be when you go back in and open menu-- not sure if this happens if you turn detector off though.
Now,,here is where other manufacturers like White's should be paying attention,,Xp as well.
I have read countless Internet forum threads and post associated with just when does the White's V3i and even the Vx3 model need to be ground balanced.
Rutus depending on what you change setting wise will give you ground balance prompt.
This is exactly what White's should have done on the 2 models I mention here.
Xp Deus,,you change freqs,,ground balance doesn't carry over,,should be a prompt..
Now detector companies,,if they do this for future models,,,they could offer a way to override the prompt,,so it doesn't appear in screen. This might be more handy for someone say who is more experience with the detector in question.
Emi,,this detector ranks right up there as being one of the quietest I have run for Vlf,,,even runs as quiet IMO as CTX and etrac,,and DST Fisher units.
Now this from judging in 2 different places with loads of light wires,,and a few transformers.
I should also say,,this concentric coil I received with Rutus is the very first one I have ever owned,,I did run a gents White's XLT with concentric some 6 years ago for around 15 minutes.
Navigating around using Rutus is different,,but not hard,,just gotta get used to it.
Unit seems to ground balance nicely here in my soil.
More to come.

Hello all...as we are getting many emails and messages inquiring about the Racer, we would like to give you a little bit more info.
The device has 2 versions - Racer and Gold Racer.
Racer is the coin & relic device and the Gold Racer is the prospecting one as the name implies. Racer will be launched first and Gold Racer will follow a few months after that. Racer runs on 14KHz. Gold version - waiting for the final testing stage.
We will be visiting USA next week to meet our distributors and upon our return we are planning to launch the product.
So we are expecting to start shipments early February if all goes smooth. Should there be any changes, I will definitely inform you.
Thank you everybody!
