Relevance assessment of exploration techniques to BIF Iron Ore exploration

I would like to invite you to complete this survey which I am running as a part of my PhD research in the University of South Australia affiliated with MinEx CRC. The results of this survey will be used to develop a quantitative framework for assessing the “exploration value” of different classes of data for mineral exploration. I would greatly appreciate it if you could give 15 minutes of your time to complete the questionnaire. All information will be anonymous, confidential, and not identifiable. I will use summary statistics in my analysis and will share the outcome of the survey with you if you choose.
1.What is your highest education qualification?(Required.)
2.What year did you graduate from that degree?(Required.)
3.What was the primary discipline area in your degree?(Required.)
4.What is your current role?
5.Have you previously been involved in exploration for iron ore?
BANDED IRON FORMATIONS - IRON ORE EASTERN PILBARA:

You are doing greenfield exploration and could invest in a range of exploration data for targeting BIF iron ore. Assuming all datasets have the same effective cost, please rank the following exploration techniques from 1 to 5 (1 = not useful and 5 = Essential) on how useful you perceive the data would be to identify the following geological features (assume you can collect the data at the desired survey or sampling resolution of your choice).
