A trillion in metals... Let me see... Let's say the asteroid is just made of pure platinum ($770/oz). That means $27 104 000/long ton. To get to $1 x 10^12 that mean an asteroid with a mass of 37 000 t. More realistic 10 ppm therefore a mass of 3 700 000 000t... Anything more of an extraction cost of $300/ton and what do you have... A big rock... As we say in the mining business, there are only two kinds of rocks, ore and waste. If you can't make money extracting something then it is waste. Your big ball of platinum/iridium etc. is probably just waste (at least at this time).
