what's the corunna deal worth to gda?

"CIMB Upgrades Atlas Iron to outperform (BUY) reducing the price target though by 20 cents to $1.50 the broker suggest its exploration results at Corunna the initial ones are significant because it has the potential to increase the companies mine life in the Pilbara and saying if the resource is proven it would certainly lead to better economics for the company".


In my uneducated opinion,the deal could be worth $2 to $3 million in revenue per year,for 10 years.

Any thoughts,anyone?
