In case you didn't get the memo, after months of underperformance relative to spot gold prices, ETFs that track gold miners are finally starting to act right. In recent weeks, perhaps the worst thing that can be said of these ETFs is that they are performing “less bad” than the broader market and in a display of their underlying strength, some of these ETFs even rise slightly on wicked down days for the broader market. And as we are seeing today, gold miner ETFs also outperform on up days. That's only part of the good news. The other part is the discussion on gold miner ETFs does not begin and end with the Market Vectors Gold Miners ETF (NYSE:

GDXJ is no slouch with almost $2.5 billion in AUM, but there is room in this niche for GGGG to thrive. GGGG, which made its debut in March and is home to 30 stocks with nearly $3.9 million in AUM, is just starting to perk up. Up nearly 5% in the past week, GGGG's gains have been made on above average volume, perhaps indicating investors are finally starting to take a look at this unheralded mining ETF.

In other words, it's a good idea to embrace mining ETFs with North America and Australia exposure and GGGG offers plenty of that. Investors can also rest easy knowing major gold miners such as El Dorado (NYSE: EG), Kinross (NYSE:
