I see DBEXF from seeking alpha but website doesn't list anything and company is listed in Toronto and Lima (only one of the mines - one of SMT's companies).
Can't imagine there is any volume even if there is a US symbol though..
FYI you can lookup symbols by typing the name of the company into the quote box on finance.yahoo.com. Symbols of companies matching what you've typed in will start to appear. So, for instance, if you type in "sierra m" and stop you'll see a handful of choices appear only one of which is a pink sheet foreign arb symbol (ending in F)
