Why tell them what they want to know. Kinross Commissioned the Service to learn how their Offer was being accepted by the ARU Shareholders.

Why fulfill their purpose by giving them the answer they're seeking. Let the Survey culminate with Kinross paying the bill but still not knowing anymore than when they initially Commissioned the Survey.

I thanked them for calling but said I considered my decision to be confidential. As such I didn't wish to share it with an unknown person at the other end of a phone call.

Hey! I was even Thanked and we parted Friends. LOL
