A “false positive” was a new concept for all of us at the mine. Between 1993 and 1998 six groups and a number of individuals came to Alleghany with either existing equipment of ideas and money to development a gold detection machine. We provided the opportunity and our contribution was to mine the targets that showed up from their detection.

After several disappointing results from our drilling, blasting and mucking the target, we became more and more critical of just what the scientists represented as a positive target. I learned that disappointment in technical research is to be expected and the scientists called these “false positives”. I did not think these were very positive after awhile but reluctantly adopted the language of science ie, “false positive”.

Some of the things we found during our part of the deal were: vugs, horses, old pieces of equipment, and dramatic changes in the quartz. A vug is a small cavity in a rock (quartz in our case). It may be lined with crystals of a different mineral or quartz crystals but the open space alters the detection response. A horse can be a splitting of the vein but what we usually identify as a horse is a large block of displaced wall rock caught along a fault or a mass of country rock lying within the vein. Signals act differently because of the physical differences between quartz and the country rock.

After many encouraging positives both false and true, we decided that it was impractical to continue the chase. Most of the errors were human(the need to get good results to encourage more working capital or sloppy work procedures); but one important concern is what is called the rock to sender interface. With radar it is important to get rid of clutter. If the rock to sender interface is not addressed, as much as eighty percent of the electrical signal creates clutter and negates much of the depth and reliability of the equipment.

Mike,
Something that might be of interest to the reader (and myself) is a description of a false positive. Is there any one thing that was found more often then not (other than the lack of gold) or a set of physical properties that was noticed when heading for the target?

There was an important new development in gold detection in the Sixteen to One last week. It reduces the time to develop the soft wear required to distinguish gold from a positive signal that is not gold but some other physical characteristic that appears positive. It also greatly reduces the costs involved in mining the targets identified by ground penetrating radar (GPR).

People unfamiliar with our high-grade gold deposit and unfamiliar with the science of blind detection cannot imagine how significant metal or gold detection is. With equipment penetrating just the depth of four feet, we have mined millions of dollars of gold from areas left by past miners. Twenty to fifty feet is attainable now by all accounts provided by people or companies working with radar detection. With this new development it becomes practical to look at all targets without the former concern of finding nothing more that the dreaded “false positive”.

The next step is to bring in the best hard ware available. I do not know where it is but now am confident that we can afford to chase these targets without duplicating the problems encountered between 1993 and 1998.

Hey folks. I'm new to the forum but not Prospecting and Treasure Hunting. I had an interesting discussion with some fellow prospectors this evening that inspired me to check out the site tonight. I'm told that the 16 to 1 is now utilizing detectors and such to discover new deposits beyond what's visible or speculated. I've had the thrill to find some beautiful specimens (both lode and placer gold) using this technique. Last year I invested a substancial sum of money in some technology that has been utilized by the government for several years and has been made available to us for the past ten. Problem is the cost of entry, but perhaps most difficult is the learning curve. My past experience with this device has proven that once I've scanned a "known" target then I can analyze the 3 dimensional image and sure enough learn how to identify other targets of the same. It has the capacity of imaging up to 60 feet in debth, depending on the type of target and other interferences. Now I've made several trips out using the device to locate lode gold and found that I also need sample scans of known targets. Once this is accomplished it will enable me to provide an invaluable service to myself and others. If anyone has any input as to how I can accomplish this objective and both parties find it mutually benificial, please let me know.

We are firm believers in the application of modern technology in the Sixteen to One mine. The wind is blowing in our direction. Security is driving the wind. Confidentiality with certificates of agreement and understanding limits just how much of the advances are reaching the public and us. Some of the small companies with leading edge developments want to keep their process close to their chests ($$$$ is a factor). Some of the large companies want to buy the small companies. One such instance has an asking price of $200,000,000. That is a lot of security machine sales. For us it would be less than a 200,000-ounce pocket! If we can attract some of these industrious, brainy scientists to venture into the mine’s Beta site, it could be profitable for everyone. I do know that tiny differences, as long as they can be measured and identified with the sources of the differences will be a great prospect in finding gold hidden by quartz. Until such time as someone pops for the money and he or she knows the potential of our mine, we remain open to all serious detection. The wind of discovery is blowing but is not yet felt.

Yes, we mined four of the five anomalies. The first was a pinching of the vein, a geologic structure and no gold. The second was a horse, a geologic term for an irregularity cutting out a portion of the vein. One was a vug, a geologic term for an open or vacant space. We did not mine the weakest remaining one after we located an old abandoned slusher.

Mike,

You mention that the RIM Technology worked locating the several anomalies, Did you mine to those anomalies, and if so what did you find when you got there? ie How much gold? You say that the technology works but that the processing the data takes time, that seems to me just a matter of manpower thrown at the problem. Finally, what is the cost of this equipment and the cost to operate it?

In 1992, we began using metal detectors in the mine. Soon other methods of locating gold surfaced, one was GPR (ground penetrating radar). It works. We were able to “see” through the quartz and an image would appear on the screen. The Discovery channel presented a ten-minute special about our work around 1994. The problem seems to rest in the interpretation of the data. What does gold look like on a computer screen? What are the other anomalies we see via the technology?

We became a Beta site for a five-year program of serious gold detection with companies interested in using modern technology to find gold. We learned a lot. The Sixteen to One mine is a great mine for research because the quartz is benign and the gold is very concentrated. Over the years the miners became familiar with the term, “false positives” (a phrase I particularly detested). No research was successful in breaking away from the ‘souped up’ hobby type detectors we were using with great success on a regular daily basis. Too bad, but we observed reasons why the others failed yet had no control over their methods.

Another type of detection came from Colorado. It was called RIM technology (radio imagining method). It also worked. We were able to locate anomalies within five hundred feet of quartz between the 1700-foot level and the 2200-foot level. One of its drawbacks was the length of time it took to process the data. Therefore, we declared that our gold detector of the future must be in “real time”. The hardware is not stopping our progress. It is the software and the adaptation of the equipment to meet the demands of an underground mine. Miners are not known to be dainty guys, and mines are known to be wet and dirty. Our future detector must be durable.

We spent a lot of time and money chasing those false positives; however we are willing to continue the search for an electronic improvement to identify the high-grade gold in the scattered but abundant pockets. (The Sixteen to One agreed to actually mine the signals or spots where the outside research companies believed showed a gold pattern.) We do not even care if the eventual accuracy is only forty percent. This is a very rich mine. We can strike out sixty percent of the time and still find a lot of gold.

“No timetable exists for us to development the 21st century gold detector. But, for all of us who pioneered the modern gold rush in California, the sooner the better. I can count these pioneers on the fingers of both hands and the toes on both feet. The ability to build and detect blind gold lodes exists. I can count on the fingers of my hands gold miners capable of writing the same assertion (to say with assuredly something that can not ever be known). There is a thing called ‘risk’. In taking the risks of this game, one hand will tally the players. There remain a few pioneers who remember and know: the ones with the highest risk will seek the highest reward. The Alleghany Mining District, which has never relinquished its soughvernity, encompasses a vein system laced with lots of gold. It is known to many but believed by few.”

Goldsmith, this is the best way I can most obtusely yet directly, answer your posting. A big question to ponder is: the technology area and allocation of gold. The choice has been to chase gold before chasing a gold detector that will surely find gold. The pocket I have in mind is one to eclipse the largest ounce concentration mined in Alleghany. It was found before the order by President Roosevelt prohibited American citizens from owning gold. This vein was mined into the size of a stope (room) about 20 feetX40 feet. It can be quickly mined also. An 84,000-ounce hit will do the deal and it will be quick.

Back to the timetable question, which by now you may see there will be no answer, the timetable for technology has less value than the time preference to sink the Red Star Shaft. Its existence depends on us finding some gold or selling some equity. Borrowing money is out of the question. (Our government has chosen debt over equity dilution. It is less important to berate this choice and instead to see who holds the notes of the debt.)

OAU rates the choices to ponder in importance as follows: gold, dilution, operation, and assets. Each of these unique areas competes for a timeline. For this reason I prepared to sell the Brown Bear mine for the $6 million to create the new shaft and also build the device. Before the Federal government’s confiscation of Americans constitutional rights to personal property in 1934, two hundred million dollars was the pay off for the minimal mining of the claims. Spending $200,000 to assemble and test the world’s deepest gold detector underground, has taken a back seat to selling an asset. Even selling the Brown Bear for 15,000 ounces is questionable when considering production of 500,000 from no levels below the drainage.

I welcome any comments. We will develop the hard and soft ware to locate gold much deeper than ever before in the Alleghany Mining District.

Is there a time table as to when this might happen. Have you been talking to different Metal Detector copanies like Whites, and Mine Lab? I would think they would be dieing to add you as a member.I can remeber the Whites adds with Mike in them.I wonder how many detectors those adds sold?

The best technology for locating and mining high-grade gold is still geology. Fortunately, the Sixteen to One vein system is a well-researched and studied deposit. Fortunately, the company recognized the importance of mapping and recording data. Fortunately, the corporation directors believed enough in the deposit to seek wealth from the ground instead of the paper profits in the stock market. The science of geology remains at the pinnacle of locating new pockets.

Since 1992, the company realized the importance of electronic detection devices that would recognize and report gold to the operator of the device. Millions of dollars were produced from the gold overlooked by the traditional methods of locating and mining a “pocket”. What would Bennet, Van Doren, Foote, Searles, Fuller, Cooke, Hulesdonk, Best, Alling, Woodbury, Furgeson , Gannett and other high-grade gold miners think if they knew that miners today can wave a wand along the quartz and gain the notion that gold may exist eight feet beyond the visible surface? Fortunately for us, no one knew until now.

The next generation of metal detectors will increase the penetration to twenty feet. The hardware already exists. The best mine in the world to advance this technology is the Sixteen to One. It is permitted. It is operating. It has a seasoned crew. It has a history of research of twelve years and it has the gold. The research to build the hardware is mostly completed.

I'm curious as to what type of technology is being used in the 16 to 1 these days to find new pockets of gold.
