[QUOTE="user 4386, post: 656840, member: 4386"] It might be but the odds are against it. Quartz going half an ounce per ton has around 15 grams gold per 1,000,000 grams of quartz. !,000,000 grams of quartz is about 431,000 cu cm. Exposed 10 m deep and in say a 20 cm wide vein, you would have to only have around that much quartz available in total to detect. And the gold won't be evenly distributed, perhaps a small number of sub-gram bits spread over that volume. But of course that tonne of quartz may have no gold specks at all…. Which is why I only bother with free gold (eg in soil) or with gold-ridden quartz in the soil or in quartz on a quartz-rich dump. Let nature or others concentrate the gold first. You really should not consider going down a shaft like that without barring down and stabilizing the collar (which, together with the above sum, is why I don't bother with old workings - too much work for too little reward).
