Homefire,
Thank you for the update.  I am new to the forum and really do not know a lot about a magnetometer or GPR use at all.  I have done some reading but not a lot.  With the characteristics being as I explained in my previous post, do you have any ideas as to what would help me to locate this quartz vein?  I believe there is enough ferrous content in the quartz to possibly differentiate between the surrounding soil and the iron in the quartz.  I just don't know how to do it at a depth of 3 to 4 feet?  I originally thought that using GPR that I may be able to distinguish between the two but just by seeing density differences.  I have never used GPR and do not know.  When I read about the magnetometer, I thought there may be a chance.  I thought that if it were not too expensive, I would try and build something myself and try it.  If you have any ideas or if you have the time to reply, I would appreciate it.
Thanks again,
BC

How do you know there is a vein?

The grandson who helped me to find the location remembers seeing the exposed quartz.  He explained that it was about 12" wide and ran the course of about 30'.  His grandfather had exposed it with a cat.  He then backfilled the area to hide it.  You may ask yourself, as i did, why is it that no one ever attempted to mine this.  At the time is was assayed, 2002, gold was at about 270.00 to 280.00 an ounce.  The grandfather died shortly after the discovery.  The grandson could not get his life together enough to even hold down a job.  He knows nothing about gold prospecting.  In the summer two years ago, I made 7 trips up there trying to dig it, detect it, anything i could think of to locate this.  The grandson accompanied me on 3 of these trips.  Nothing.  I spoke with him not long ago and he told me he has not been back and is not interested in helping me as he cannot afford it.

The area would be still scared in some way I would think.

The entire area, approx. 50' x 50' is scarred.  The problem is the soil is absolutely impossible to dig.  It is very dense clay.  I need to locate an approximate location to dig before i start.  The only way i have determined that i will be able to dig it is to auger holes, ( i have already priced gasoline powered auger equipment) drill the holes every 8" or so and work at it until i can get it broke up.  BUT, i need an approximate place to start.  Going at it random will take forever and be alot of work.  So, any ideas on how to locate it?

Hi, BC,

I also think your best bet is to use a ground resistivity measurement device rather than a mag.
First, this type of device is much easier to build by amateurs and, second, this vein should probably be more easily detected with this technology even if it does not contain any iron material.
However, if you are still interested in a magnetometer, send me an E'mail (w.Bayot@skynet.be). We are selling a good and rather cheap working magnetometer.

Hi Willy....Can a Magnetometer be utilized for deep buried treasures? Up to 16 ft.

Mags only respond to Ferrous / Iron materials.
