Stream Financing的一般解释是：

A metal stream financing deal works in a fairly direct manner. A precious metals royalty company or a royalties companies that does volumetric production payment royalties or resource purchase agreements (commonly metal stream companies) will offer a given amount of money per ounce, pound or tonne of a given ore type. For instance, a metal stream deal for gold might involve a metal stream company providing $300 per ounce upfront to the resource developer. This capital, likely provided on a staged basis as the junior mining company reaches mine build milestones, is used to assist with the financing of the mine.
