The A-1 occurrence is A-1 drill hole (Assessment Report 5202), located approximately 1.5 kilometres 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 lies approximately 1 kilometre to the northwest.
Locally, the area is underlain by the Upper Triassic Savage Mountain Formation (Takla Group) rocks. The 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 which ranges from hornblende and/or biotite granodiorite to quartz diorite. These rocks are cut by basic dykes, generally less than 3 metres thick, which are finely feldspar porphyritic (Assessment Report 5202).
Copper mineralization is hosted within the intrusion and occurs as chalcopyrite with minor bornite and associated pyrite in fractures and quartz stringers. Malachite staining is present along the fractures. Two 3.3-metre drill intervals assayed 0.09 per cent copper (Assessment Report 5202). Gold and molybdenum values are typically low. Another 3.3-metre drill interval assayed 0.17 gram per tonne gold (Assessment Report 5202).
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 analyzed 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 high 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.
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).
In 2019, Peter E. Walcott & Associates Limited undertook an induced polarization survey over parts of the Arjay/Goldway property for Serengeti Resources Inc (Assessment Report 39133). In total, some 7.8-line kilometres of induced polarization surveying was completed on two traverses. The program was completed in order to test for the presence of chargeability and resistivity features below and adjacent to anomalous geochemical copper, gold, and silver values and airborne magnetic anomalies. Results of both IP surveys at Arjay-Goldway were reported to have displayed strong chargeability and resistivity results. One east-west line line was put in about 3 kilometres south of Asitka Lake. The other line had its southern point about 800 metres west-northwest of the Asitka Lake mineral occurrence (094D 146) in a significant creek valley, extending north-northeast within the valley (and beyond) for a total of about 3.5 kilometres, about 1 kilometre east of the A-1 drill hole/occurrence.
See A-4 (094D 087) for general characteristics of mineralization first discovered by Nomad Mines Ltd., on their Asitka Claim group/property. Also see A-4 for a more complete work history, including work done outside of the original Nomad claims.
