The Memekay 1 occurrence is located on a ridge between Cooper Creek and the Memekay River, approximately 1.7 kilometres south west of their junction.

The area is underlain by sediments of the Jurassic Harbledown Formation (Bonanza Group) or Triassic Parson Bay Formation (Vancouver Group) and basaltic volcanic rocks of the Triassic Karmutsen Formation (Vancouver Group). These have been intruded by dioritic intrusives of the Jurassic Island Plutonic Suite.

Metasedimentary rocks in contact with mafic intrusive rocks are exposed in logging cutblock roads in the Memekay River area. The exposures include the Memekay 1 occurrence, the Memekay South area, and Memekay 1.5 and Memekay 2 areas.

Locally, at the Memekay 1 showing, a 34 metre long zone of brecciated and pervasively silicified metasedimentary rocks with cherty horizons is exposed. Epidote and chlorite are identified with silica as alteration minerals. Sulphide mineralization ranges to 2 per cent mauve-coloured sphalerite, 1 per cent chalcopyrite and a trace of pyrite. Analysis of chip samples returned 0.196 per cent copper, 1.358 per cent zinc and 4.953 grams per tonne silver over 34 metres (estimated true thickness of 12.4 metres) including 0.251 per cent copper, 0.733 per cent zinc and 6.293 grams per tonne silver over 11 metres and 0.296 per cent copper, 2.636 per cent zinc and 7.654 grams per tonne silver over 5.5 metres (Minland Resources (Jan. 17, 2005): Summary Report on the Memekay Property for Minelan Resources by Jacques Houle, P.Eng).

A boulder found in the Memekay South area, approximately 100 metres southwest of the Memekay 1 occurrence, returned values of 0.786 copper, greater than 1.00 per cent zinc, 12.50 grams per tonne silver and 0.001 per cent molybdenum (Minland Resources (Jan. 17, 2005): Summary Report on the Memekay

Property for Minelan Resources by Jacques Houle, P.Eng).

Memekay 1.5, located approximately 500 metres south-southwest of Memekay 1, consists of an exposure of black and grey sulphidic metasedimentary rocks and banded metasedimentary rocks in contact with the mafic intrusive rocks.

At the Memekay 2 area, located 400 metres southeast of Memekay 1, a mafic intrusive and mafic intrusive breccia are in contact with metasedimentary rocks.

The Memekay 3 area, 350 metres east south-east of Memekay 1, has altered metasediments, mafic intrusive rocks and feldspar porphyry. Sampling and analysis of these three additional areas however, returned no significant results.

Other copper-gold sulphide occurrences, Thunder and 4th of July, are reported to be located on ridges to the east of Cooper Creek and west of Kay Creek. No other information is available.

The Memekay 1 occurrence was discovered by ground prospecting by Minland Resources prospecting partnership in 2001. The showing and immediate area was subsequently mapped and re-sampled in December 2004.
