The 518 zone is located on Victoria Creek, about 9 kilometres north-northeast of Stewart and approximately 1.5 kilometres east of the Stewart highway (37A). The showing lies about 750 metres northeast of the Main Reef occurrence (104A 067).

The area is underlain by north-northeast striking, west dipping argillites, cherts and siltstones of the Middle Jurassic Salmon River Formation (Hazelton Group) (Bulletin 58; 63).

The 518 zone is exposed in a cliff on the west side of Victoria Creek. North striking, west dipping pyritic and cherty bedded argillite is intruded by a 30 metre thick feldspathic sill. The upper and lower contacts of the sill are bleached and mineralized with patchy sulphides. A massive vein of quartz and arsenopyrite cuts the sill. The vein is up to 0.8 metre wide, trends 100 degrees and dips vertically. Narrow wallrock alteration comprises sericite, quartz and disseminated pyrite.

Grab samples from the showing collected in 1990 assayed up to 21.3 grams per tonne gold, 270 grams per tonne silver, 14.47 per cent arsenic, 0.0955 per cent copper, 0.355 per cent lead and 0.0127 per cent zinc (Assessment Report 20975). Drillholes intersected hydrothermally altered rocks with disseminated mineralization in altered mafics. Drilling results in 1991 were disappointing.

The Hill Top zone occurs about 270 metres east of the 518 zone on a hill underlain by silicified and mineralized argillites, andesites and intrusive rocks. Mineralization consists of arsenopyrite, pyrite, and pyrrhotite in a quartz stockwork cutting granodiorite. A wide zone of gold enrichment was intersected in drillhole MM-1. Assay values were 0.544 gram per tonne over 29.5 metres (Assessment Report 22053).

A showing may have been known at this location in the 1920s (or earlier), when the area was covered by the Star 1-2 claims, owned initially by Horstman and then later Victoria Mines, Limited (see 104A 067). In 1990, the mineralization was rediscovered during prospecting and geological mapping on the MM 100 claim by KRL Resources Corp. Airborne and ground VLF-EM and magnetometer surveys were also completed at this time. Drilling on the 518 zone was done in 1991 by KRL Resources and the Hill Top zone was discovered at this time. During 2017 through 2020, Singer Resources Inc. and American Creek Resources Ltd. completed programs of geochemical sampling, a 13.5 line-kilometre induced polarization survey and a 438.5 line-kilometres airborne magnetic and LiDAR survey on the area as the Dunwell property.
