Woah.... :swoon:
At Australian Mint, History Thwarts a Golden Opportunity (http://online.wsj.com/articles/in-australia-perth-mint-has-valuable-gold-dust-in-its-walls-1407983401)
I read that article!
Wouldn't it be nice to demolish that place!!
When gold mine processing plants are being demolished it's common practice to crush all the concrete footings and send them for treatment to extract the gold which has seeped in over the years. Sometimes the proceeds can pay for the demolition work.
When wifey and I visited the Perth Mint approx. 10 yrs ago, we were advised that a few years before, they vacuumed the dust off the rafters etc in the melt room and they were able to retrieve several ounces of gold from the dust.
If they get that from the dust, what will they get from the bricks?
