I don't think you can argue, as the article kind of does via its sources, that these "discoveries" are of questionable profitability due to the infrastructure and security investment that will be required AND they were the lucrative reason we went to war in the first place.

After all, if the Afghan War has already cost the US $739.8 Billion dollars [1], even $1 Trillion doesn't leave much for infrastructure investment and a reasonable profit margin.
