The Asitka 19 occurrence is located within the Asitka 19 claim unit (Assessment Report 5202). The showing is approximately 400 metres east of Asitka Peak and 15 kilometres west of Johanson Lake.
The regional geology is similar to that of the A-4 occurrence (094D 087), which is approximately 1 kilometre to the northeast.
Locally, the area is underlain by the Upper Triassic Savage Mountain Formation (Takla Group). This formation consists of greenish to red-brown intermediate porphyritic flows, chloritic tuffs and agglomerates, and minor intercalated epiclastic sediments. These stratified rocks are intruded by the Early Jurassic Asitka Peak stock. The stock ranges from hornblende and/or biotite granodiorite to quartz diorite. The rocks are cut by mafic dykes, generally less than 3 metres thick, which are finely feldspar porphyritic (Assessment Report 5202).
In 1973/1974, Nomad Mines Ltd discovered copper mineralization hosted within northwest trending quartz and chalcedony veins. The veins are associated with shear zones and stockworks which cut the volcanic rocks. The veins, stockworks and shears are typically malachite-stained and contain chalcopyrite and bornite (Assessment Report 5202). The veins occur in close proximity to the southwest boundary of the intrusion. A zone of similar mineralization exists for approximately 300 metres to the southeast.
In 1991, International Corona Corporation revisited the Asitika 19 area, collecting 9 rock samples. The highest copper value obtained (2.38 per cent) was from a malachite-bearing float sample highest copper value obtained (2.38 per cent) was from a malachite-bearing float sample of pyroxene porphyry basalt (64184) of pyroxene porphyry basalt (Geochemical (Sample) Map, Assessment Report). A nearby 0.3-metre chip sample (64182) from a quartz carbonate vein hosting bornite and malachite graded 0.8 per cent copper (Geochemical (Sample) Map, Assessment Report 22018).
WORK HISTORY.
West Point Mines Limited staked the Sil and Jim groups (30 claims) in 1965. The company name was changed in 1966 to Black Giant Mines Ltd. Additional staking was done during 1966 to a total of 185 claims. No work was reported and the claims subsequently lapsed 1968 and 1969. In 1969, the Chalco claims were staked by W. Sevrens, covering part of the property later owned by Nomad Mines. Nomad Mines Ltd. acquired the Asitka 1-24 claims from principals of the company by an agreement of March 1972. The claims surrounded Asitka Peak on three sides, the west, north, and east. Additional staking was done in the Asitka and Bob groups to a total of about 60 claims and fractions. Cash in lieu of assessment work was paid in 1972 and the first exploration by Nomad was carried out during the 1973 field season when a preliminary exploration program consisting of geological mapping, prospecting, line cutting, geochemical soil sampling (479 samples) and a magnetometer survey was carried out. This program resulted in the location of widespread copper mineralization. In 1974, Nomad collected a total of 407 soil samples and analysed for copper and molybdenum (Assessment Report 5202). The copper geochemistry roughly outlines a northwesterly-trending zone of discontinuously mineralized quartz veins. On the Bob group, only a few higher copper values are outlined. There is a general correlation between high molybdenum values in soils and the main northwest trending body of anomalous copper values. Four diamond drill holes totaling 676 metres were completed in 1974; holes ranged from 160 to 185 metres in depth.
In 1981, prospecting was conducted in the area northeast of Asitka Peak by John Mirko (Assessment Report 9546). In 1981, a portion of the property was restaked as the Asitka Peak claims and minor prospecting and sampling was completed. In 1989, area northeast of Asitka Peak was restaked as the Asitka 1,3 and 4 by K.V. Campbell. Minor geochemical soil and rock chip sampling and prospecting was conducted (Assessment Report 20006).
The SIT claim group, staked in 1990 for International Corona Corporation, includes the Sit 1 (242823, Sit 2 (242828, Sit 5 (242831), Sit 6 (242832) and Sit 7 (242833) claims. Geological mapping and prospecting were performed in 1991, visiting and documenting previously discovered mineral showing and making new discoveries as well (Assessment Report 22018). Work included 25 man-days in the field, when 100 rock and 24 moss mat samples were collected. A large area between Asitka Lake, on the south, and Johanson Lake on the north, was prospected by Corona. See A4 (094D 087) for related geological and work history details.
In July of 2018, John Bot a contracted R. Beck Consulting Services to conduct a short sampling program along the gossanous hillside of the western flanks of Asitka Mountain (Assessment Report 37708). Eleven of 12 samples collected during the program were taken along a northwest trending traverse west of Asitka 25 (094D 097) and Asitka 29 (094D 094). A more significant sample was taken between Asitka 10 (094D 148) and Asitka 19 (094D 096).
