Well, maybe they can sell you a bar or two. The truth is that no legit junior explorer promotes itself by pouring copper bars....or silver bars, or any kind of bar. It is the kind of gimmick used by sleazy penny stock scammers.
Gimmicks like nonexistent gold-detecting satellites. And idiot plasma technology to smelt ores. And new, made-up terms to measure gold values, like grams/meter.
