There was a boom not long after and I sold the shares at about $11 each. The gain was sufficient to buy myself a flash [albeit second hand] Yamaha YDS5E [250cc] to replace my aged BSA Bantam Major [150cc] which was past its use-by date. That was a very major upgrade. I had found my calling. I had cash left over. So I was in the mining business in Oz half a century before you and not far from your site. I can testify to the profitability of it. If you want to find gold in tailings, take a look down stream from the Martha Mine at Waihi. maps.google.co.nz Type "Waihi" in the search box, zoom in, you will easily see the mine. Then follow the river downhill heading west from Waihi, which flows past Paeroa and on north to the Firth of Thames. Martha Mine here: waihigold.co.nz Over millions of years, the whole Karangahake gorge was eroded and the sediment is now deposited at Paeroa and on north and into the Firth of Thames. There is umpty mega million tons of sediment sitting there, with loads of finely ground gold among finely ground sediment from finely ground rocks. The Karangahake gorge was one giant gold mine 100 years ago. The Talisman mine was one of the most productive in NZ: teara.govt.nz I drive through the gorge frequently, with the gold ghosts looming all around. With modern technology, I have been imagining a mechanical mole which could eat away under the surface, pumping the sediment to the processing plant floating on a barge, separating the gold and silver, depositing the sediment back into the tunnels previously bored. With computer mapping of previously bored sediments, the worm would not need to repeat any previously drilled areas. One could buy swarms of 3500 ft2 Hong Kong ocean view apartments from the proceeds. Mqurice
