    I'm looking for claim-friendly location(s) to test a new magnetometer system that I developed to map now-buried former stream courses by sensing and mapping black magnetite sand deposits close to stream locations historically known to have produced significant gold. Help with digging these potentially rewarding locations also wanted. My involvement would be totally at my expense. (TopoMag project.)

    Mr. DONALD LAND:
    Sounds very interesting. I can only imagine my becoming involved with such an endeavor. And yes, I'd be game in becoming involved. Yet I see a problem, presently. For example, in California, I know that governmental peoples presently overstep legal authority here in California. And with such as your magnetometer system so to map-out gold & possible gold locations, along with the required digging & testings, lookouts would be required lest all equipment be "confiscated".
    .
    Therefore your "claim-friendly location(s)".
    .
    I know that the "magnetometer" has been around for decades, yet advanced technology & the mapping out of iron flows & deep pockets of iron & such HAS TO BE cutting edge for today's foot-soldier prospector.
    Are you an engineer? or an electronic wiz? or simply insightful, as I already see that you are. Sir, I feel the excitement all over this.
    So what are your plans? Private lands within the western coastal states? Or open lands in Nevada, New Mexico, Arizona?

    Hello Jim,
    Yes, I am a retired engineer (electronics and software), and I have customized my marine MagSurvey software for use with my hand-carried magnetometers (see magsurvey dot com for info on this similar software, and on some of my electronics capabilities).

    I share your concerns about excessive regulation from governments, especially within the Pacific states, and would prefer to run testing in mountain-time-zone states, such as Wyoming, Idaho, Colorado, or perhaps the others that you mentioned). Considerable digging could be involved. If you could zero-in on appropriate locations, perhaps we might meet up there for testing.

    Just curious on your product. I see you are in West Palm...I am here in Ft Lauderdale. I am wondering just how your system would be working if the buried ancient streams are down under 5 or 10 feet of overburden? Is it relying on the metal detector's depth capabilities to find the black sands?

    Hello Leo,
    A magnetometer is a very specialized "metal" detector -- it can only detect the presence of ferrous metals, such as iron, and how they locally affect the strength of the earth's magnetic field. Certain proton and electron-spin magnetometers do have a longer sensing range than other metal detectors in these conditions -- my mags are the proton precession type. Of course, the amount of magnetite deposited will greatly affect the variation of the detected field.

    yes I am fully familiar. In fact, mining companies already use these methods on mapping out potential gold silver deposits. They fly aircraft over areas, mapping magnetic anomalies on the earths surface. As you probably know, the earths crust exhibits much polarization lines of flux running north and south and deposits in the crust can be affected via fault lines, shear zones ect and tectonic plate movement and abnormal readings are great indicators for possible PMG elements. I know guys using metal detectors searching only for heavily mineral surface streaks to hone in on possible gold deposits. A metal detector is basically a magnetometer, to a certain extent. But then again, it doesnt mean there will be gold to find. I know all about the treasure salvagerss using equipment like yours to locate new undersea wrecks here on the east coast and other locations around the world.

    Hello Leo,
    I'm also familiar with the use of magnetometers to locate shipwrecks, and have been selling magnetometer surveying software that I developed for that purpose for over fifteen years (magsurvey.com). The software component of TopoMag is similar to MagSurvey, but modified for land use.

    I had been considering driving out to mountain-time-zone states to test my equipment (I drove to Wyoming to prospect last year -- pre TopoMag project completion). Instead, I'm now considering running tests at a couple of the new GPAA claims in Alabama this summer. Are you familiar with Alabama prospecting, and yields?

    Well as far as Alabama no I am not. I go out to Nevada quite often and am very familiar with that topo and the minerals. At least out there you dont have to restrict yourself to GPAA claims. The land is free in Nevada! So much of it is BLM and you can roam for miles and miles and get the feeling the land is yours. I have been in areas where there is no gold but yet the black sands would drive your system crazy. Iron or black sands is only an indicator to improve the likely finding of gold. Doesn't mean there is gold either. I do know exploration companies employ those tactics to determine anolomies in the surface which would indicate minerals deeper down. Not sure how deep your system detects these magnetic changes.

    Not sure of TopoMag's reliable depth sensing range yet -- just guessing six to eight feet. I'm going to need to get out into the field very soon for some testing in actual gold-known areas. Just finished the purchase and outfitting of a used Aliner popup camper for use as a base of operations.

    Mr. Land:
    How wonderful -6 to 8 feet would be wonderful.
    I understand you must get out into the field ASAP. I apologize for not being available @ present for you to utilize my labors in the advancement of your software testings & such.
    .
    I did visit your website and was wondering the size of the power source. Not important here, just wonder how far advanced magnetometers have become. My only experience / education pertaining to has been via post World War II USGS reports. I think such devices were used with helicopters? And setting a charge here & reading it over there (topo) & so on. With today's computers & software & electronics (et al.) & all, I know I am behind the times. Still, how exciting!
    .
    I will keep in-touch. I will also contact you later this year to touch base & hopefully with the possibility of meeting &/or going out into the field together. At that time, I plan to present to you what intel. I have. I hope it all will be within your ball park.
    For now, all the best. And many updates & improvements & new findings within your software (& hardware) design(s).
    Jim

    Hello Jim,
    Thanks, please do keep in touch. Proton mags are relatively power-hungry, so I'm using a three cell 11.1V rechargeable lithium ion battery pack (often stated as 12V) -- label says 20AH, but retailer admits that's a bit of a stretch. Anyhow, I should get several hours of use between the long charges.
