The Kli occurrence is located on a northeast flowing unnamed tributary of Kliyul Creek, approximately 12 kilometres east of Dortatelle Peak (Assessment Report 3977).
Regionally, the area is underlain by Upper Triassic Takla Group volcanics that are intruded by the Early Jurassic Hogem Batholith to the south. To the east, the rocks are intruded by leucocratic granodiorite of the Early Cretaceous Kliyul Creek body. Two northwest trending, elongate, Late Triassic, Alaskan-type ultramafic bodies occur in the general area. The major structure in this area is the north trending Dortatelle fault. Smaller faults trend northwest.
Locally, the area is underlain by flat-lying andesitic flows overlain by interbedded shale, limestone and sandstone. These are intruded by quartz monzonite dikes, which trend northwest and are parallel to shearing and schistosity. The intrusive rocks, consisting of quartz monzonites and an ultramafic body, generally outcrop on the northeast side of Kliyul Creek.
Mineralization is related to a silicified, and highly pyritized zone, that marks the contact between the volcanic flows and sediments. Silicified zones are also common along shears and fractures. Visible mineralization consists of irregularly disseminated chalcopyrite and pyrite in these "skarn" contact zones. Epidote, calcite and garnet are associated with these zones.
Approximately 500 metres to the east, on Kliyul Creek near the confluence with the unnamed tributary, is another chalcopyrite showing. This showing is hosted in an altered band at the ultramafic-andesite contact.
The claims were originally staked in 1971 to cover a copper stream silt anomaly by El Paso Mining and Milling Company Limited. Anomalous silts, with values of 178 to 320 parts per million copper, were found over 1.6 kilometres of the north fork of Kliyul Creek (Property File Cyprus Anvil El Paso Mining and Milling Company Limited, 1972).
In 1972, four-man crew put together by El Paso Mining and Milling Company completed 13 days of reconnaissance geological mapping and stream silt sampling over the Kli 9-48 claims. A total of 73 stream sediment samples were collected and analyzed. Some rock sampling was done. The area of the Kli (094D 019), Cro 2 (094D 176) and Mal (094D 141) was mapped and prospected (Assessment Report 3977). Very little copper mineralization was observed except in several float occurrences. However, silicified zones with pyrite were seen to occur along shears and fractures in andesite near the intrusive contact and to some extent in the intrusive particularly towards the northwest end of the property.
In 1992 Noranda carried out 1:5,000 scale geological and alteration mapping and in 1993, they drilled 6 reverse circulation holes on the Kliyul skarn zone (094D 023) (Assessment Report 23033) and followed up with an airborne magnetic, EM, and radiometric survey that extended to the south (Assessment Report 23379). This airborne survey also covered (or nearly covered) 25 MINFILE occurrences including the Kli (094D 019), Lady Diana (094D 092), Karen Creek (094D 145) and DBC (094D 177).
