The area of the Lynes showing is underlain by phyllites and limestones of the Cambrian to Devonian Index Formation, Lardeau Group. A pluton of monzonite to granodiorite belonging to the Middle Jurassic Selkirk stocks intrudes the metasediments, developing mineralized skarns.

A 10 meter-thick exposure of dolostone or dolomitic marble is cut by a series of variably mineralized veins that dip nearly parallel to the steep topography. The host rock strikes north to 010 degrees and dips about 40 degrees east and displays fracturing seams and veinlets or patches of crackle breccia. Malachite staining is common.

Mineralization occurs in quartz veins that appear to be tension gashes displaying an en-echelon pattern or sometimes in a less organized arrangement. Sulphides are predominantly galena, as irregular medium- to coarse-grained knots or ragged aggregates up to 25 cm across, and lesser finegrained tetrahedrite that may or may not be associated with galena. Accessory chalcopyrite and sphalerite also occurs as knots, and they too may occur in association with galena or isolated from it. A series of 10 channel samples chipped from a blasted 10 meter-long slope-face yielded grades as high as 7.8 per cent lead and, in a separate sample, 1.1 per cent copper with 3.4 per cent zinc; a sample from material thought to be subcrop yielded grades of up to 14.1 gram per tonne gold (Assessment Report 27696).

Orphan Boy Resources staked the Rain 100 and Rain 200 claims in January 2004 and followed up with prospecting, trenching and diamond drilling along with grid cutting, and on parts of it, soil geochemical and magnetometer surveys. Only limited work was completed on the large group of properties held by Orphan Boy.
