I'll quickly deal with geoscience and royalties.
One dollar in public geoscience usually generates four or five dollars in private sector spending, because you're usually going from regional scale mapping to project specific mapping, which is like a 1:50,000 ratio as opposed to 1:250.
In terms of what obligation companies have to disclose their work, again, most provincial as well as territorial mineral tenure regimes have a requirement for the company to post its geoscience findings to keep its claims in good stead, if you will. So there is a fair degree of disclosure. Clearly, if you're a competitor, you have to go data-mining, but most mining recorders' offices have those reports if they are submitted.
In terms of royalties, the federal government, through Aboriginal Affairs and Northern Development, does collect royalties based on the value of production for both diamonds and gold. In Meadowbank I think the transfer from the federal government to the NWT was in excess of $1 billion. I think maybe $300 million in royalties was collected. Aboriginal Affairs and Northern Development collects the royalty, which is submitted to the Receiver General and then gets paid out through equalization payments, and those kinds of things.
The only direct calculation we do north of 60 is for the claimant groups that have settled a comprehensive land claim. There is a resource revenue-sharing calculation that's prescribed through their respective comprehensive land claims.
