The Lorraine showing is situated near the headwaters of Ladner Creek, approximately 300 metres south of the Pipestem mine (MINFILE 092HNW011).

The area is underlain by grey to black, locally organic-rich, pyritic slaty argillite intercalated with well-bedded siltstone, all assigned to the Early and Middle Jurassic Ladner Group. A number of northwest- striking bands of medium to very coarse-grained, tuffaceous, fossiliferous wacke also occur within the sequence. The bands vary from 5 to 45 metres thick and are the principal host to gold mineralization. Greenstone assigned to the Lower Triassic Spider Peak Formation is in contact with these sediments to the southwest.

The sedimentary rocks have all undergone a complex history of structural deformation characterized by folding and several north to northwest-striking faults. The wacke bands are also cut locally by a pronounced fracture cleavage. These rocks have been intruded by narrow sills and dikes up to 4 metres thick. Several porphyritic felsic sills, similar to those associated with gold occurrences in the Siwash Creek area (MINFILE 092HNW004, 005, 015-017), host thin quartz veins with pyrite.

Locally, a 15 metre long by 4 metre wide mineralized zone is hosted by silicified, chloritic wacke and argillaceous siltstone. Mineralization consists of numerous cross-cutting quartz-albite-calcite veins with pyrite, arsenopyrite, pyrrhotite and minor chalcopyrite.

In 1982, 10 continuous 1-metre wide chip samples from a trench south of diamond drill holes LCN 81-14 and 81-15 averaged 3.53 grams per tonne gold (Assessment Report 11158).

In 1996, a chip sample across the mineralized surface zone assayed 6.34 grams per tonne gold, while a drill hole sample from L3-95 assayed 40.2 grams per tonne gold over 1.2 metres (Assessment Report 24561).

During 1976 through 1978, Longbar Minerals completed programs of soil sampling and 9.0 line-kilometres of ground geophysical surveys. In 1980 and 1984, Aquarius Resources completed programs of soil and rock sampling program on the area. In 1982, Carolin Mines completed a program of geological mapping, rock and soil sampling, trenching and 19 surface diamond drill holes, totalling 1721.51 metres, on the area. During 1994 through 1996, Athabaska Gold Resources completed programs of geological mapping, geochemical sampling, trenching and four diamond drill holes, totalling 282.54 metres, on the area. In 2012, New Carolin Gold completed airborne magnetic and radiometric surveys, totalling 759 line-kilometres, on the area.
