In all likelihood, the drilling has nothing to do with the PEA.

So it will not impact the delivery date one way or the other.

As per the press release "The program is also designed to fulfill obligations under an agreement with Cliffs Natural Resources Exploration Canada Inc. that allowed Zenyatta to acquire 100% of Albany graphite deposit."

I suspect this drilling is related to the "Zenyatta Second Option" that will allow Zenyatta to increase its ownership of the surrounding clains from 25% to 80%.
