The Sha South geochemical anomaly is located on the Sha 29 and 30 claims, approximately 8 kilometres west of Yahk (Assessment Report 22057). Reconnaissance geophysical surveys by UTEM (University of Toronto electromagnetic) method disclosed several low-level conductors on the claims (Assessment Reports 17044, 18163, 18164). Earlier horizontal-loop electromagnetic and ground magnetic surveys had also shown several weak conductors and anomalies (Assessment Report 11210).

The area is underlain by the peri-cratonic Middle Proterozoic Purcell Supergroup, a thick succession of siliciclastic and lesser carbonate rocks. The Purcell Supergroup is well known for hosting a number of significant deposits that include the Sullivan (082FNE052) sedimentary-exhalative lead-zinc deposit and the Troy copper-silver deposit in Montana.

The claims are underlain by quartzitic turbidites and argillaceous siltstones of the Middle Aldridge Formation. No mineralization is reported, but spot highs of up to 200 parts per million lead and 250 parts per million zinc were found in soil samples (Assessment Reports 15025, 22057).

From 2010 to 2012, Eagle Plains optioned the property to Purcell Range Exploration Ltd. The exploration program conducted included airborne geophysical and gravity surveys, soil geochemistry survey, geological mapping, and prospecting.
