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 Hattie showing is located on the east side of Erie Creek, about 12 kilometres southwest of Ymir. This showing, along with the Copper King (082FSW213), the Arnold (082FSW301) and the Ben Hassen (082FSW300) showings, occur on the Erie Creek property.

The area is underlain by Lower Jurassic Archibald Formation, Rossland Group 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. Hornfels is mainly developed in argillite and siltstone. Chlorite occurs mainly on fractures and in shear veins in augite andesite and hornfels.

Drilling and prospecting have identified molybdenite mineral- ization on fracture surfaces and in quartz veinlets within quartz monzonite. Molybdenite with pyrite, pyrrhotite, minor chalcopyrite, and rare scheelite is disseminated in quartz veinlets associated with a quartz stockwork texture and as selvages on fracture surfaces. The mineralization, associated with the Erie Creek dyke swarm of felsic and mafic dykes, is not confined to the intrusive suite. Weak quartz-sericite-pyrite alteration occurs in envelopes along and adjacent to fractures and molybdenite-quartz veins.

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 diametre 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. The 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, occur finely disseminated and as fracture coatings. Sphalerite and galena with some gold occur in shear veins beyond the inner zone, such as the Arnold (082FSW301) and Ben Hassen (082FSW300) showings.

The inner quartz-molybdenite plus or minus scheelite zone is approximately centered on the Hattie or June 2 claim. Host rocks are quartz monzonite dykes and stock, and white rhyolite. Grades in the zone range from 0.01 to 0.059 per cent molybdenum; 0.0166 to 0.196 per cent copper and 0.005 to 0.14 per cent tungsten (Assessment Report 15510). Best results reported by McIntyre Porcupine Mines were 85 metres of 0.115 per cent MoS2 and 0.05 per cent copper, including 30 metres of 41.14 grams per tonne silver (Assessment Report 15510).

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. This showing is interpreted as occurring in the central stockwork zone.
