The CX 2 occurrence is located just west of Terrahina Creek, about 49 kilometres east of the community of Atlin.

The area lies within alaskitic quartz monzonite of the Late Cretaceous Surprise Lake batholith (Surprise Lake Plutonic Suite) and along the western edge of the "Trout Lake graben". Organic-rich lacustrine sediments contain values to 0.048 per cent uranium (ca. 1977, Assessment Report 6448). Sediment samples from nearby radioactive springs assayed up to 0.15 per cent uranium (Journal of Geochemical Exploration, 1981).

In 2006, Aldershot Resources Ltd. conducted a spectral analysis program on their Atlin East property which covers the CX (104N 114), Mir 3 (104N 113), Mir 7 (104N 112) and CX 2 occurrences. The program involved acquisition of satellite spectral data available from NASA, reconfiguring the data into a workable format, geo-referencing to TRIM map bases and extensive and rigorous classification of the data in search of indicators that might lead to the discovery of uranium mineralization.
