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.

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).
