TGB has been around a long time and is profitable so I don't think I'm taking a huge chance but obviously the copper price is approaching all time highs so caution is probably good advice. Small position as well.
Amerigo has also been around a long time. Similar potential is Cerro de Pasco, GPPRF. Waiting for them to get access to the huge tailing piles. Many years of waiting. Luckily I only bought a few weeks ago at US$.08392 so will take partial profits once they get the stupid permit that they've been expecting "any day" for several years. I thought US bureaucracy was bad!
Miners are starting to wake up. Copper, silver, gold. Is it finally time? Or another disappointment? We'll see.
