Capsule Geology

The Shamrock occurrence is located approximately 5 kilometres southwest of Nelson. Minor production has been reported for this claim.

The area is underlain by augite basalt flows, breccia flows and subvolcanic intrusions of the Lower Jurassic Elise Formation, Rossland Group. These have been intruded by plagioclase porphyry of the Late (?) to Middle Jurassic Silver King Porphyry.

No geological description is available but a total of 7.7 tonnes of ore grade material was shipped in 1937 and 1948, which yielded some silver, lead, zinc, and minor gold. This occurrence is likely similar in setting to the Silver King deposit (082FSW176).
