In a recent provincial geological compilation based on mapping by Hoy et al. (Open File 1994-8), the probable area of the Juditta prospect is underlain by undivided sedimentary rocks of the Triassic Brooklyn Formation. Nearby, a belt of Devonian to Permian rocks occurs immediately west of the fault contact with a Proterozoic gneiss complex (Grand Forks Gneiss). The northerly trending Granby River fault is inferred to be the eastern margin of the Republic graben, a fault bounded package of rocks that extends north from Washington State. The Paleozoic rocks, consist primarily of greenstone, chert and argillite and limestone of the Knob Hill Group. Intruding the stratigraphy of the area are granitic plutons of the Jurassic Nelson Intrusions and dikes, sills and intrusions of the Eocene Coryell Plutonic Suite which are syenitic to monzonitic in composition.

In 1899 the Richmond and Alpine Fraction claims, owned by Frank McGuire and W. Hamiltion were situated half way up the Pathfinder wagon road, where it crosses the creek. Tunnels had been run in from the creek bottom on either side for distances of 24 metres each exposing an irregular quartz vein from 30 to 45 cenimetres in width. The Richmond claim (Lot 2232) was reported to be Crown-granted to Frank McGuire in 1901 and again to Albert Savage in 1907.

In 1923, a group of claims, consisting of, the Juditta, Robson, Richmond and Morelli, were owned by John Morrell and associates, of Grand Forks. Small segregations of mixed-grade ores, consisting of galena, chalcopyrite, pyrite, gold and silver were reported to occur. On the Juditta claim, two shafts had been sunk, 3.7 and 6 metres respectively, also a tunnel 6 metres long. The bottom of one of the shafts is mineralized in the fractures with galena and pyrites containing gold and silver. Samples of picked galena ore from the shaft assayed 2.06 grams per tonn gold, 686 grams per tonne silver and 20 per cent lead (Minister of Mines Annual Report 1923, page 180).

In 1927, the Juditta and Restake claims, were owned by John Morrell of Grand Forks. The country-rocks were reported to be chiefly volcanic tuffs and andesites, with remnants of limestone in contact with granite and ganodiorite. Pyrite mineralization was general throughout the tuffs, with occasional segregations of pyrrhotite, galena, and sphalerite.

In 1998, Cassidy Gold Corp., while working on their larger Pathfinder (082ESW075) and Little Bertha (082ESE074) property, examined the area south of Hornet Creek. They reported mineralization consisting primarily of disseminations of pyrrhotite and/or pyrite most often within metasedimentary rocks. One occurrence of very minor chalcopyrite was noted. However, no mention of workings along the creek was made. Please see Pathfinder (082ESE075) and Little Bertha (082ESE074) for a history of the larger overall Pathfinder property that in recent years has largely been held in common and worked by various companies.
