    But that may be on the high side.
    That seems pretty concerning on its face, though I wonder what the concentration would be after dilution in the lake.

    As you point out, the legal question is different from the policy one. The legal result seems fine, though the policy one is more iffy. There's an intrinsic revulsion toward the idea of dumping anything in a lake, but it isn't clear (to me at least) that such a policy would be that much worse than the alternative:

    This plan would require filling about 100 acres of wetlands, and the tailings pile would eventually be about 150 to 200 feet high and about 1200 to 2000 feet wide on each side.

    Interesting case either way.

    Gold is pretty useful outside of bling.

    It's used for dental crowns and bridges and it is an excellent conductor as well.
    Overall its some pretty cool stuff.

    I used to make crowns and bridges with it in a dental lab.

    This is Alaska; a 23 acre lake is a puddle, put 50 of them together and you have an ornamental pond.

    Don't all of you have environmental problems in your own (tiny) States that need your attention?

    You do grasp that all of that came out of the ground, right?

    Gold - Wikipedia, the free encyclopedia
    It dosen't. Some crowns and bridges are made from gold, so people can bling their smiles. But, other things can be used that perform as well or better.

    I have no idea what gold conducts. Since gold mining has begun, we have collected no more than would fill a football stadium. So tell me, what do we use it for other than bling???

    From a great article in National Geographic:

    No single element has tantalized and tormented the human imagination more than the shimmering metal known by the chemical symbol Au. For thousands of years the desire to possess gold has driven people to extremes, fueling wars and conquests, girding empires and currencies, leveling mountains and forests. Gold is not vital to human existence; it has, in fact, relatively few practical uses. Yet its chief virtues—its unusual density and malleability along with its imperishable shine—have made it one of the world's most coveted commodities, a transcendent symbol of beauty, wealth, and immortality. From pharaohs (who insisted on being buried in what they called the "flesh of the gods") to the forty-niners (whose mad rush for the mother lode built the American West) to the financiers (who, following Sir Isaac Newton's advice, made it the bedrock of the global economy): Nearly every society through the ages has invested gold with an almost mythological power.

    As for it's impact on the environment:

    Gold mining, however, generates more waste per ounce than any other metal, and the mines' mind-bending disparities of scale show why: These gashes in the Earth are so massive they can be seen from space, yet the particles being mined in them are so microscopic that, in many cases, more than 200 could fit on the head of a pin. Even at showcase mines, such as Newmont Mining Corporation's Batu Hijau operation in eastern Indonesia, where $600 million has been spent to mitigate the environmental impact, there is no avoiding the brutal calculus of gold mining. Extracting a single ounce of gold there—the amount in a typical wedding ring—requires the removal of more than 250 tons of rock and ore.

    All that for bling. Not worth it, IMO.

    Please read the rest of the article. It's an excellent and informative read.

    If you lived on that lake or close, would you be cool with it?

    Are you serious? Gold is one of the most useful industrial metals fore several reasons, including its high electrical conductivity, almost unbelievable malleability and resistance to corrosion. if it wasn't used for jewelry, it would still be in high demand.

    Heck, yes. We're trying to get a different kind of mining here right now.

    If I lived there, I would probably be trying very hard to get a job with the mine.

    It's sooooooooooo precious, that if it wasn't used for jewelry, we'd use it for important stuff?

    Yes, it is all those great things you mentioned. So why do we use it mostly for bling? Why is that? Please, I wanna hear it from you.
