The Ing occurrence is located on a north-northeast trending ridge at the headwaters of the Ingenika River (Property File - Canadian Superior Exploration Limited, Maps from Company Files, c. 1973), approximately 14 kilometres west-northwest of Johanson Lake.
The regional geology is similar to that of the Copper King occurrence (094D 149) which lies approximately 5 kilometres to the northwest.
Locally, the area is underlain by the Upper Triassic Savage Mountain Formation (Takla Group) which is overlain by the Lower Jurassic Telkwa Formation (Hazelton Group). These successions of predominantly volcanic rocks are intruded by an unnamed Early Jurassic quartz diorite intrusion. Stratigraphically, the oldest rocks are pyroxene porphyry flows overlain by bladed feldspar porphyry flows. These volcanics belong to the Savage Mountain Formation and are overlain by a mixed package of pyroclastics which include a well-bedded waterlain sequence, agglomerates, breccias and lapilli tuffs which may belong to the Telkwa Formation (Assessment Report 5256). These rocks are cut by quartz diorite intrusive bodies.
The strata dip gently to the west and are moderately fractured and jointed. The dominant joint attitude is 45 degrees, dipping 85 degrees to the northwest with a secondary pattern trending 160 degrees, dipping 75 degrees to the west (Assessment Report 4593). Local faulting and shearing generally trends northeast and west.
At the location, mineralization occurs as chalcocite in a 10-centimetre-wide epidote vein, cutting bladed feldspar porphyry (Map 2, Assessment Report 4593). This type of mineralization is typical for the ridge. A drill hole tested a narrow, discontinuous, mineralized shear zone filled with narrow, erratic, chalcocite-bearing carbonate and epidote veinlets (Assessment Report 4593). The drill hole is located approximately 900 metres along the ridge from the vein.
WORK HISTORY
The Ing occurrence was documented by MINFILE in 1992 but was first discovered in 1973 by Canadian Superior Exploration Limited on their Z claim group. Work during 1973 by Canadian Superior included geological mapping and a reconnaissance geochemical survey comprising 80 soil and 40 silt samples over 6.4 line-kilometres. Silt geochemistry showed generally high copper background values in the 200 to 500 parts per million copper range (Assessment Report 4593). Numerous creeks were anomalous, particularly in the east-central and north-west portion of the Z claims. In addition, 80 soil samples were collected at 200 foot intervals along 5 reconnaissance lines and the samples were analyzed for copper. The results showed widespread copper mineralization, values ranging from 15 ppm to 660 parts per million with the anomalous threshold at 100 ppm copper (Assessment Report 4593). BP Minerals Ltd. optioned the Z claims in 1974 and continued work.
In 2015, Pacific Empire Minerals Corp completed an IP line that trended southeast from the Copper King showing (094D 149) towards ING (094 151).
In early 2017, Pacific Empire completed ASTER data processing and analysis on the Copper King property, covering 4178.2 hectares (Assessment Report 36615). The survey covered all occurrences on the Copper King Property including D.S. (094D 004), Bornite (094D 037), Copper King (094D 149), Nika (094D 150), Ing (094D 151), Geni (094D 152) and Jo (094D 153).
In 2016 and 2017, airborne magnetic surveys were flown on behalf of Pacific Empire Minerals Corp over the Copper King Property totaling 109 line-kilometres (Assessment Report 36613, 36815). The survey covered all occurrences on the Copper King Property including D.S. (094D 004), Bornite (094D 037), Copper King (094D 149), Nika (094D 150), Ing (094D 151), Geni (094D 152) and Jo (094D 153).
See Copper King (094D 149) for related geological and work history details of the larger Copper King property which included the Ing occurrence and several other documented MINFILE occurrences.
