dave wiseman Posted April 15, 2007 Report Share Posted April 15, 2007 Exciting! Did you find any gold in it?As an extension of what Randyasked,you may want to pan all the dirt outside and inside.Though the chances are remote if you come across a copper amalgam plate from a mill,be sure to scrape it clean.....Dave Quote Link to comment Share on other sites More sharing options...

We have the GPS track and do plan on going back with a detector.Bunk Quote Link to comment Share on other sites More sharing options...
Admin nuggethunting Posted April 16, 2007 Admin Report Share Posted April 16, 2007 Hello Bunk, Keep in mind most Arrastra's were used for "Free Milling" ores and not very far from the mine or prospect they were working. I've always found some ore with visible gold around Arrastra's in Arizona! Might be worth poking around that area a bit more.

BIGFOOT Posted April 16, 2007 Report Share Posted April 16, 2007 Miner Matt & Others,Makes me wonder HOW many other Arrastra's are out there that had a fire started in them(to shatter the rock,cement,ore OR burn off any amalgam)that were forgotten and left as a campfire location.......hhhhhhmmmmm...........I can hear you diggers thinkin from here!GO GET IT!!!

29prospector Posted April 17, 2007 Report Share Posted April 17, 2007 Miner Matt and Others,Its good to hear someone say they don't want to ruin or destroy Arrastra's. If you have a good Metal Detector and a strong Vac, you came check and pretty much clean the inside out without ruining it. In the 3 pictures below, all the gold I found was around the outside and mine area. EnjoyO'29er in 29 Quote Link to comment Share on other sites More sharing options...
whats4supper Posted April 24, 2007 Report Share Posted April 24, 2007 There are two variations of arrastras:one is the old drag a big rock around in a circle sort of thing. among other things, the floor will show scrapes and scouring, and quite a bit of wear. Where possible, many of this type had a basalt floor because it could take a lot of wear.the second variation is the Chilean Mill. Instead of a drag stone, it had one or two big round stone wheels. easier to turn, and milled the ore a lot finer. The wheels would last a lot longer, and the flooring wouldn't wear down as fast. Other grades of rock beside basalt could be use to build the pit.Besides vertical wheels, sometimes the wheels were laid flat, one on top of the other, ore introduced via holes in the upper stone, which turned on top of the stone wheel on the bottom. In South America, stone Chilean mills are still in use, while some of the all steel types are in use all over the world.One version of the chilean mill: http://digital-desert.com/mining-equipment-chilean-mill/Another blurb (Montana related) http://www.deq.mt.gov/AbandonedMines/linkd...ocs/182tech.aspand a picture of one used in North Carolina http://www.lib.co.rowan.nc.us/HistoryRoom/...m/Mining/27.htm Quote Link to comment Share on other sites More sharing options...
