The Omega occurrence is located approximately 6 kilometres due east of the southern tip of Johanson Lake, centred between two 1982 diamond-drill holes, about 122 kilometres northwest of Germansen Landing (Map 3, Assessment Report 10686A).

The area is regionally underlain by the Upper Triassic Takla Group volcanics. The volcanics are bound to the north by the northwest trending Lay Range fault and to the west by the north trending Dortatelle fault. This succession of volcanics has been intruded about 5 kilometres to the west by small Early Jurassic quartz dioritic stocks. The volcanic rocks in the area include andesitic volcanics, porphyritic (mainly pyroxene with lesser hornblende and feldspar) andesites and andesitic dikes. Granodiorites and multi-lithic breccias also occur locally.

Initial work indicated two main areas of surface mineralization, a Contact zone and a Breccia zone. In the Contact zone chalcopyrite is disseminated in granodiorite at a breccia contact. The Breccia zone trends in a northwesterly direction apparently for a continuous length of 320 metres; dips range from 35 to 50 degrees southwest. The breccia is unusual in that it has a bedded or sheeted nature wherein angular thin plates to massive slabs of andesitic, dioritic, and pyroxenitic rock sit in a matrix of rhodochrosite, quartz, and chlorite with erratic clots and veinlets of chalcopyrite, pyrite, and minor amounts of magnetite. Chalcopyrite is also disseminated in the dioritic fragments.

All rock types contain mineralization in the form of disseminations and vein material. Bornite and chalcopyrite occur with associated pyrite in quartz-epidote veins and as disseminations within the breccia. Molybdenite, along with associated magnetite and pyrrhotite, occurs in quartz veins, fractures and shears. Chlorite and hematite also occur in some of the mineralized veins. A 3.0-metre drill intersection consisting of mineralized andesite assayed 0.53 per cent copper and 4.8 grams per tonne silver (Assessment Report 10686B). Drilling revealed 0.22 per cent copper and from 0.34 to 4.8 grams per tonne silver over 52 metres in a highly altered and erratically mineralized vertically extensive breccia zone pipe in hole LC 82 1; and a pyrite halo with minor molybdenite mineralization in hole LC 82 3 (Assessment Report 10686A).

In 1981, Silver Standard Mines Ltd. staked the Breccia 1, 2 and 3 claims. In 1982, after optioning the Breccia property, Lornex Mining Corp. proceeded to conduct soil sampling, magnetometer and induced polarization (IP) surveys, mapping and a small drill program on the Breccia (1) claim. A total of 388 soil samples were collected from the Breccia claim grid area. In 1983, Lornex Mining Corp. completed a program of prospecting, soil geochemistry, ground magnetic and VLF surveys primarily on the Breccia 4 claim which they had staked in 1982, to the northwest of the Omega zone, on the Lay Creek showing, In total, 66 rock samples and 351 soil samples were taken.

The Breccia property was dormant from 1983 to 2011.

In 2011, International Samuel Exploration Corp. bought 100 per cent interest and rights to the Breccia property and renamed it the Omega property. They completed a program that included an airborne magnetic survey (301 line-kilometres), a ground IP survey (21 line-kilometres), and geological prospecting. The geophysical survey results yielded a high chargeability area that correlates well with high copper geochemistry from historical and current data. The prospecting and sampling program was undertaken two days and a total of 49 rock samples were collected and analyzed.

In 2012, International Samuel Exploration Corp. conducted a ground IP survey which indicated the 1982 drilling narrowly missed the core of the IP anomaly.
