I'm happy to do that.
With respect to the mineral exploration tax credit, it relates to flow-through share investors. Under a flow-through share investment agreement a person can purchase shares from what's generally a junior mining company. Junior mining companies very often do not have enough revenue to fully offset their expenses, so under a flow-through share agreement those expenses can be renounced by the junior mining company to the flow-through share investor. The expenses that are eligible to be renounced relate essentially to greenfield exploration—prospecting; sampling; geophysical, geothermal, and geochemical analysis; and those sorts of things.
Expenses can be renounced to the investor up to the amount of the share investment, and then the mineral exploration tax credit provides a 15% credit on the amount of expenses that are renounced to the shareholder. To fully take into account the effect of the fact that expenses are renounced and are deductible by the individual investor, as well as having a 15% tax credit, in the year following the year in which the claim is taken, there is an income inclusion in respect of the amount of the credit.
Certainly a number of industry associations have indicated the importance of this credit to their prospecting activities. In particular, I had talked about junior mining companies. It's of particular importance to them. As I indicated, they may have mining exploration expenses that they're not able to take into account in computing income tax.
