N2  - The need for a more effective tool to explore for channel hosted detrital iron ore deposits under post mineral cover has led to the development of a novel minimalistic seismic refraction survey method we call &#x2018;Sparse Refraction&#x2019;, to map the depth of cover over basement. The survey configuration employs a single source and a single receiver, at a fixed offset. The source-receiver pair are moved progressively along a traverse, and at each station a first break reading is recorded. Gravity data is also acquired. Combining the two datasets allows the target response to be isolated from the gravitational effects of palaeotopography &#x2014; we call this residual gravity field the &#x2018;Excess Mass&#x2019;. The method allows large areas to be screened quickly and effectively, with low environmental impact.This paper describes the journey from understanding the exploration problem, finding a solution, and the successful implementation of the new approach.
