A number of things worry me about drawing inferrences from these graphs.

1. The debt ceiling extrapolation is pure guesswork.

2. Once you have positioned one plot, the other can be placed anywhere you like since the start height and the scale of the second plot are not determined in any way by the first curve.

People usualy make the two plots coincide at the start and adjust the scale of the second plot to get the best "fit."
In this case, this was done in 2011 not at the end of the data used.

3. If there is a resemblence between the two plots, people often infer correlation. This brings up another issue, namely that you can't justify a correlation no matter how good it appears, unless there is an established, indisputable dependence of one (POG here) on the other (Debt ceiling.)

Luckily the price of PGI will be determined largely by how quickly and how well the mine ramp-up goes.

I expect after vaguely assimilating all the info I sift through that POG will rise to over 1800 USD this year. PGI share price will get a lift from that.
