DDCNagi-SLW is a silver streamer. Not a miner. Not an ETF.
They pay an up front "fee" to say, a Gold Miner who has mined, as a by product, other metals,ie; silver.
The up front fee funds the miner and for that fee, SLW receives the silver for a certain number of years or life of the mine, at MUCH lower costs than current spot price. Spot price could go up or down. Their deal is fixed.
SLW also has a gold contracts.
Some will say they paid too much for their contracts and some say they have negotiated great contracts in place.
There's so much more to it, but hope that's a start.
And,just my op.
For someone who claims to have such a mastery of the English language (though many of us see through your foofy, fluffy, self-aggrandizing verbosity) , it's somewhat laughable that you don't know the plural of prospectus ("prospecti").
