The property is located at a 1067 metres elevation on the west side of Erie Creek, extending south from Grassy Creek, some 24 kilometres south-southwest of Nelson.

The Dora claim (Lot 5152) was Crown-granted to H. Porter in 1901. The following year the adjacent Drum Lummon (Lot 5481) was Crown-granted to P. Bums and the Homestake (Lot 3433) to The Copper Farm Gold Mining and Development Company, Limited. No work was reported but Map 52-13 A shows two adits in this vicinity.

The Consolidated Mining and Smelting Company Limited held an option on this ground in 1928 and diamond drilling was carried out.

Canzac Mines Ltd. in 1967 held Mineral Lease M 129 comprising the above claims and the adjoining Copper King (5153), Goodenough (5466), Monte Carlo (1066) and Nelson (12177), located on and extending south from Grassy Creek. The company also held Mineral Lease M 125 comprising the Rosa (2460), Belle (2461), Florence (3237) and Bully Boy (3238) reverted Crown-grants located about 1.6 kilometres to the south between Skillet and McKay creeks. The Hattie 1-32 claims were staked over the adjacent area, extending east of Erie creek to Young Grouse Creek, a tributary of Burnt Creek. Map 52-13 A shows an adit in the vicinity of the Rosa claim. Trenching was reported in 1967.

McIntyre Porcupine Mines Limited optioned the claims from Canzac by an agreement dated March 1968. Work by McIntyre in 1968-70 included geological mapping, a geochemical soil survey and 1703 metres of diamond drilling in 12 holes. Wollaston Lake Mines Ltd. acquired all the assets of Canzac Mines in 1969. The company name (Wollaston) was changed in 1971 to Comaplex Resources International Ltd. Under the option agreement McIntyre had to form a new company to acquire the property and accordingly Dalhat Mines Limited was incorporated March 1971 with Comaplex holding a 30 per cent share interest. Additional claims (Dal 1-17) were apparently staked at that time. Work in 1974 included geological mapping and an induced potential survey over 11.2 kilometres.

Canamax Resources Inc. apparently acquired the property.

The Copper King showings are located on the west side of Erie Creek, about 13.5 kilometres southwest of Ymir. The area was first explored in the 1890's. The workings, comprising numerous pits, adits and trenches, on the Drum Lummon, Copper King, Homestake and Dora claims are all now included in the Erie Creek property. There is only sparse information on these individual claims. The Arnold (082FSW301), Ben Hassen (082FSW300) and Hattie (082FSW226) occurrences are also part of this property.

The area is underlain by the Lower Jurassic Rossland Group Elise Formation volcanics and Archibald Formation sediments. The Rossland Group rocks are intruded by the Middle to Late Jurassic Nelson Intrusions, locally known as the Erie stock. The Erie stock is comprised of a light grey quartz monzonite with associated aplitic and feldspar porphyry dykes. Biotite hornfels is apparently a contact metamorphic effect related to both the Nelson batholith and the Erie Creek dyke swarm. It is mainly developed in argillite and siltstone. Chlorite occurs mainly on fractures and in shear veins in augite andesite and hornfels.

Mineralization on the property occurs roughly in four concentric zones. An inner quartz-molybdenum plus scheelite zone followed by a chalcopyrite zone, a pyrite-pyrrhotite zone and an outer sphalerite- galena zone. The inner zone is approximately 600 metres in diameter and is centered on the east side of Erie Creek. The host rocks are quartz monzonite dykes, stocks and white rhyolite. The chalcopyrite zone occurs over an area of 1.5 to 2 kilometres and occurs in quartz and sulphide veinlets as fracture coatings and in shear veins with pyrite, pyrrhotite and minor amounts of scheelite. Best copper values obtained, up to 1.3 per cent, were from vein and dump samples mainly from old workings on the west side of Erie Creek (Drum Lummon, Cooper King, Dora, Homestake). Pyrite and pyrrhotite, in an area about 1.5 by 2.5 kilometres, occurs finely disseminated and as fracture coatings. Sphalerite and galena with some gold occurs in shear veins beyond the inner zone, such as the Arnold (082FSW301) and Ben Hassen (082FSW300) showings.

On the Copper King claim stripping in 1934 exposed an irregular quartz vein over 11 metres. The vein, hosted in greenstone intruded by aplite dykes, strikes 345 degrees and dips 35 degrees east. Up to 1 metre of vuggy quartz contains greenstone inclusions, pyrite and arsenopyrite.

On the Dora claim, an open cut exposes an aplite dyke which has been fractured and filled with quartz, pyrite, galena and arsenopyrite. The Dora adit near the eastern boundary was driven on a mineralized stockwork in white rhyolite and may be within the inner quartz-molybdenum plus or minus scheelite zone although there is no documented evidence. In 1987, a sample of hornfels with chalcopyrite, taken from the northeastern boundary of the Dora claim, assayed 20.2 grams per tonne silver and 0.445 grams per tonne gold (Assessment Report 15510).

The Drum Lummon workings comprise four adits in argillaceous rocks described as hosting chalcopyrite mineralization in fractures.

Sampling done in the vicinity of the Drum Lummon, Copper King and Homestake workings in 1987 had low assay results (Assessment Report 18478).

The mineralization is believed to be part of a zoned porphyry type deposit which has a central quartz vein stockwork zone containing molybdenum-copper-tungsten mineralization and a peripheral zone with veins containing copper, lead, zinc and silver mineralization. These showings are interpreted as occurring in the peripheral zone, since there is no documented evidence of molybdenum or tungsten mineralization.
