A stream is a sale of production at a fixed discount for the life of a mine. Priced correctly it is a sensible instrument. Priced under pressure it transfers most of the upside to the financier permanently.
Read the tail
The economics rarely bite in the first three years. They bite when the mine extends, when the grade improves, or when the price rises, all of which accrue disproportionately to the counterparty.
The disclosure gap
Stream obligations are frequently discussed as financing and reported as revenue reduction. Investors deserve both figures in the same table.
Why streams look cheaper than they are
The upfront payment in a streaming deal is easy to compare against the cost of raising equivalent capital through a share issue, and on that comparison alone a stream often looks like the cheaper option, particularly for a developer whose share price is trading well below what management considers fair value. What that comparison misses is that the stream's true cost is a call option sold on decades of future production, priced using an assumed mine life and gold price at the point of signing. Extend the mine life, as exploration success frequently does, and the effective cost of that capital, measured in dollars per ounce foregone over the full life of the asset, can end up dwarfing what an equivalent equity raise would have cost.
A useful discipline for any developer considering a stream is to model the implied cost of capital across a range of mine life and price scenarios, not just the base case used in the financing presentation, and to compare that range against the cost of the equity alternative on the same scenario basis.
The counterparty concentration question
A handful of specialist royalty and streaming companies now hold claims across a large share of global development-stage production, which raises a separate question about concentration: what happens to a project's financing terms and operational flexibility if its streaming counterparty is itself under financial pressure, or simply takes a more aggressive stance on contract interpretation than it did at signing. These agreements typically run for the life of the mine, which can be several decades, over which time the relative bargaining power between the two parties can shift considerably from the position at signing.
None of this makes streaming an illegitimate form of finance; it has genuinely opened projects that could not otherwise have been built. It does mean the instrument deserves the same scrutiny of long-run cost that any other multi-decade financial commitment would receive, rather than being assessed solely on the size of the cheque at signing.
