Derf, With copper, a few years back I had an ETF (CPER), but it ended up causing problems at tax time. Using SCCO and other mining stocks seems like a good approach.
One thing with miners in general though is the geopolitical risk. With periodic leadership changes in these countries, it can result in problems like nationalization of the mines, etc. Historically there's a lot of 'payola' that goes on to buy off the local politicians. There's also the increasing environmental rules to contend with.
But copper is a 'must have' for the 'electric everything' paradigm, so it seems like a logical area for investors. The longer term SCCO chart has been volatile, but overall looks pretty decent. I see they recently lowered their dividend by 20%, though it's still a nice yield.
