What small gold companies pay the highest dividends?

It's hard to find any. Talon Metals (TLO.TO) has a 4.2% yield, but they're mostly an iron producer. African Gold Group (AGG.V) has a 3.6% yield, but financial information on the company is hard to get. DRDGOLD (DROOY) is a small South African gold producer with a 1.4% dividend yield. All the other gold producers with any dividend yield, like BVN and Newmont are large (>$1B) companies and they're going to be in the 1.4% range.

Gold mining is a capital-intensive industry. Large producers tend to put capital into developing new mines rather than returning capital to shareholders in the form of dividends. Small companies need all the capital they can get to maximize production. If you're seeking dividends, gold miners are not a good place to look.
