Goldcorp, one of the largest gold miners in the world, has just come off a year of restructuring that helped it lower AISC by roughly 4% to $856 an ounce and swing to profits from losses in 2015. But it's the miner's recent growth moves -- including its acquisition of a 25% stake each from Barrick and Kinross to become a part-owner in Cerro Casale -- that should get investors excited.
Since a self-directed IRA gives you full control of your investments, you are free to add any type of precious metal coin or bar to your portfolio, as long as it is IRS-approved. If you are investing a large amount in precious metals ($100,000+) many recommend a healthy mix of gold, silver, platinum and palladium. If you are investing a small amount (e.g. $5,000) focusing on one metal is probably a more common strategy. Since every portfolio is different, we highly recommend speaking to both your financial advisor and a trustworthy gold IRA custodian before making any investment decision.
Mining-focused ETFs. That's why you might prefer to own an index-based product, like a mining-focused ETF. Some options here include VanEck Vectors Gold Miners ETF and VanEck Vectors Junior Gold Miners ETF. Both invest in gold miners (with the same caveats about exposure to other metals), but as you can tell from their names, they do slightly different things: The latter focuses on smaller gold miners. The expense ratios here are 0.53% and 0.54%, respectively. If you're looking for a single investment that provides broadly diversified exposure to gold miners, then low-cost index-based ETFs like these are a good option.  
As the gold became harder to find, the American prospectors became resentful of the explorers from other countries, all trying to get a piece of the action. They became violent towards them, and the California State Legislature even passed an act which charged a monthly tax on these “alien” adventurers to pacify the Americans. They were just as bad to the Native Americans. Skirmishes and violence between miners and explorers and other groups became commonplace. There were many deaths.
Barrick is the gold mining leader, both in terms of size and low operating costs. Company guidance calls for all-in sustaining costs (AISC) of just $765 to $815 per ounce for 2018. The gold miner cranked out an impressive $1.5 billion in free cash flow (FCF) in 2016, which may have contributed to a 42% dividend hike to investors that year. FCF ticked downward in 2017, but Barrick is still generating enough to secure continued payouts, and the dividend yield is currently 1.05%.
