The Big Splay showing is located on the southern ridge of Mount Cowley, approximately 22.1 kilometres north east of Creston. The showing has been explored, since 2010, by Fjordland Resources Ltd. as a part of the Big Kahuna property. Previous work was completed by a local prospector, Craig Kennedy, during the 1990’s and later by Kootenay Gold Inc.

Regionally, the area is underlain by clastic sediments of the Middle Aldridge and Creston Formations, part of the Proterozoic Belt–-Purcell Supergroup. A sequence of possible Cambrian age shallow- water sediments has been mapped in the north-central portion of Leadville Creek. Structure in the area is dominated by the northwest- trending Leadville Creek Fault and the northeast- trending Old Baldy Fault.

Locally, there is a strong zone of silicification, pyrite flooding, goethite, manganese, sericite, and phyllite alteration in Middle Aldridge Formation sediments.

During 2010, samples SK10-178 and SK10-181 from this zone returned values of 1.5 and 1.2 grams per tonne gold, respectively (Assessment Report 31659).
