In the following video, Fool contributor Dan Caplinger explains the basics of the silver streaming business model that Silver Wheaton (WPM 0.92%) uses to contract with partner mining companies.

Dan also highlights a new agreement with Brazil's Vale (VALE -0.63%) as an example of a new partner streaming agreement that features a focus on gold. Can Silver Wheaton continue to profit from future agreements with partners such as Barrick Gold (B 1.13%), Primaro Mining (PPP), and Hudbay Minerals (HBM -1.37%)?

Dan discusses how the price of silver may affect Silver Wheaton's dividend, which is currently based on 20% of cash flow. And he also points out why the Federal Reserve's change in tone regarding future stimulus policy is a factor that investors should monitor closely.
