    From the research I did today I have at least found out I am looking for "barrel quartz". Yet to see a sample of rough ore containing barrel quartz. ... anything I have posted already an example of stone containing barrel quartz or is that too generalized by describing the shape and not really any other distinctive quality?

    It's a lot of work, even if you have a small jaw crusher and milling/pulverizer.

    No it's better to prospect first.
    That's the ticket. Sample sample sample. When you find what your looking for you'll know it. Its a lot of work to crush rock to powder. Start by breaking things open with a rock hammer. No need to reduce it to dust. That how you'll learn whats good and what isn't in your district. Every district is a little different. Eventually you'll b able to tell by looking if its worth further examination or not. Gold usually travels in pockets and fractures, a couple whack-taps will let you know if a piece is worth bringing home or not. I am not sure what barrel quartz is but I am sure if you keep looking for it when you find it you will know what it is.

    Just looked up barrel quartz. Shaping the Landscape | Two Types of Gold Deposits | Gold in Nature | Gold: A Nova Scotia Treasure
    You'll know it when you run across it. The pictures of quartz you've shown so far may have originated from the gold bearing barrel quartz formation in your locality. Float. Broke off the main vein and floated off so to speak.
    If the gold is associated with other mineralization (iron, copper, lead, ect) I would be looking for quartz stained with those minerals. If the gold came in pure quartz them by golly I might crack open every piece of quartz I see.

    In mining its essential to understand your locality (geology and history) and sample extensively.

    A quick search https://en.wikipedia.org/wiki/Gold_m...in_Nova_Scotia it sounds like the gold is associated with sulfide mineral arsenopyrite.

    The demand for arsenopyrite a mineral associated with gold in Nova Scotia...
    Gold-ish color, shiny, smells like garlic when you break it or when it gets wet. Iron Arsenic and Sulfur compound. Real nasty. Beware. My inclination on that stuff is let it R.I.P. Rot In Place. Have to research it but my guess is the gold is in close association with or locked up in the arsenopyrite. Not trying to be a wet blanket but any way you cut it arsenic isn't real nice to have to deal with. Roasting is neither a safe or ethical option. A couple people are researching how to safely oxidize the arsenopyrite, free the gold, and lock up the arsenic in a less bio available compound for safe disposial. Bioleaching arsenopyrite and other sulphide based ores.

    Post some pictures if you find some. Then you'll be on the money.

    Maybe a gold type detector with a 4-5" coil could 'See or pick up' a sample this size one would just have to try it out.

    Looking at those photos you provided and examining rock samples I have I would say these are all made of the same quartz you displayed with heavy mineralization.

ID:	1489557 this one same story ... white crystal throughout and minerals.

    Found all 3 very close together and appear to have snapped off near by larger formation sticking out of the ground. Looks like hobbitsville where the stones are lol. The reason im so determined on these stones and area is finding this on the same location Click image for larger version.

ID:	1489559 makes me think im not the first to "be here"

    I have a gold pan in route, should be here Tuesday as well as a rock hammer. More answers soon, I am wanting to not poison myself through inhaling during my exploring so Im leary to start cracking stone until I have more info.

    Water sample taken on location and ran metals test on it. (No gold test part of that test) but has 38ug/l arsenic copper 112, iron 106, manganese 447, nickle reads greater than 2, silver reads higher than 2, strontium 75, thallium, tin, titanium, uranium, and vanadium all greater than 2 and zinc reads 52. Yet more info I have but no real understanding of. Lol Trace uranium sounds interesting


    I am going under the impression that arsenic is going to go hand in hand with the gold / minerals I find. Face mask and gloves good enough for protection? Story says a woman died in waverley in the 70's from arsenic poison ... her well tested at five thousand ug/l. Was national news again I believe in the early 80's

    Sounds like your just cracking open quartz float?Any visible surface veins in place?

    I would say no to an exposed vein. I believe Im in the looser stuff on top of it thats hardened together. Im digging down into better concentrated minerals im hopeing

    Lens, dental tool, sample bottles, and 100 mesh sifting pan on its way too ... should be here 2 days after my pan and hammer ... I probably havent found gold. But I will. Next order will be for rock crusher, magnetic seperation tool, and 50 mesh sifting pan.

    Impatience grew. Old hammer met old smooth rock like god put the two in front of me I guess. I didn't think the handle could take use. Anyways .... this snapped off an end ... looks like minerals to me

    Its confusing still 4th dimensional thinking about what to look for. Found a huge quartz boulder same location, if there is a bottom to it then its at least 600lbs ... then stumbled across this today "In the early days of mining, a one hundred pound boulder found at Montague contained 77 troy ounces of gold, then worth $1,600. In 2012, that same boulder would be worth $135,000
    http://novascotiagold.ca/theme/explo...ntague-eng.php

    Im in an area between waverley and montague trying to track the movement and source of stones of quartz that are out of place.

    Waverley is the hilly area and the waterways
    Montague is the high lands directly above waverley on a sort of plateau / rolling treeland

    When these veins form ... it is molten quartz squeezing up between sedement rocks which can be seen in sheared off rock faces? ... would the vein pop to the surface as well in a small localized area like a "mini volcano" on a slope? spitting out bubbles of moulten material possibly? The closer bubbles bigger and rounder ... the smaller ones rolled further and lost roundness due to rolling while hot until stopped and cooled in more of a stubby cylinder shape with round edges? One of the boulders sticking out of the ground like a "tongue" where it sat and cooled unejected?

    Hello
    Until some values are found it is hard to say what kind of quartz the values are in as well as near by. The values could be in very small pockets to even veins in or near the quartz. If there is any written history about this could be a good place to start looking.

    Veins that do not surface are called blind veins.Money is made out of a hard rock gold mine by the fine gold that is found and extracted,not from a rich specie or even pockets of gold.Gold goes in and out in a vein.Some parts of the vein carry gold in varying amounts(ore shoot) and other parts may be barren.Seems like your breaking up quartz float to find what.....From the Ballad of Reading Gaol by Oscar Wilde..Every rock one breaks by day,becomes one's heart by night.

    Good points. Does the area have a history of fine values in a vein or is there other deposits as well? Breaking rocks in a tailing pile could be worth the time. Breaking up quartz float if you don't know the source of can be 'Heartbreaking'.
    The goal should be to find a source and history is a good indicator for this. Maybe there is some tailing piles in the area?

    Hello
    If there is a history of only fine gold in a vein and if the vein 'Cuts out' for say 40 feet this could be the reason why the mining stopped in that area. The 'Old timers' often moved on because of this. This is the nature of 'Hard rock mining'.
    If one finds only fine values this could be a factor of how to mine in that area. Any one can find 'Colors' the question is how much 'Colors' per ton'?

    Entirely fair, Gold Rush Days ... a local heritage celebration in Waverley begins this week. I plan on attending the info session on gold panning they are holding (assuming they will be providing rich materials for thier demonstration) and looking for any historian breaking down what went on back then. Museum will be open and I'll poke around for display samples.

    Both of the mines in Waverley and Montague were started upon discovery of quartz boulders bearing gold. They took surface rocks, panned streams and Lakeview, mined ore out of veins. I know they milled the ore and did bleed the gold out using chemicals. The disguarded tailings have approx 30-40% gold value remaining after that process was complete from what Im hearing. Going to attempt to acquire info on tailings from images at the museum and chatting with the oldest people who attend the festival lol. My guess is anyone alive who worked there would be pushing 95 years old or better at this point.
