The Asitka 25 occurrence is located within the Asitka 25 claim (Assessment Report 5202). The showing is approximately 1.5 kilometres north 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 east. 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. The stratified rocks are intruded by the Early Jurassic Asitka Peak stock. The stock ranges from hornblende and/or biotite granodiorite to quartz diorite. These rocks are cut by mafic dikes, generally less than 3 metres thick, which are finely feldspar porphyritic (Assessment Report 5202).
Molybdenite and chalcopyrite are disseminated and fill fractures, in the intrusive, associated with sericite and pyrite alteration (Assessment Report 9546).
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. 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). Two samples contained 0.08 per cent and 0.12 per cent copper (Assessment Report 37708). These two samples were collected a few hundred metres southwest of Asitka 29 (094D 094) and a few hundred metres north-northwest of Asitka 25 (094D 097).
WORK HISTORY.
In 1965, 185 claims were staked by Black Giant Mines Ltd. covering all of the ground later owned by Norad in 1973/1974 as well as the rest of small mountain range to the southeast of Asitka Peak. A detailed program of prospecting and mapping as well as limited diamond drilling and blasting of trenches was carried out. This work was concentrated in the area southeast the Nomad holdings. However, some blasting was done in other area as follows: three trenches on the Bob group, two cuts on the chalcocite vein showings, on the ridge northwest of Asitka Peak and one shallow trench on the skarn showings near the extreme southeast corner of the property.
The Black Giant group lapsed in 1968 and in 1969 the Chalco claims were staked by W. Sevrens, covering part of the property now owned by Nomad Mines.
No work was done as these claims lapsed in 1970. In 1971 part of the later holdings of Nomad Mines Ltd. was staked; however. cash in lieu of assessment work was paid in 1972 and the first exploration by Nomad was carried out during the 1973 field season. In August and September, 1973, a preliminary exploration programme consisting of geological mapping) prospecting, line cutting, geochemical soil sampling 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 were collected and analysed for copper and molybdenum (Assessment Report 5202). The copper geochemistry roughly outlines the 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 were completed ranging from 160 to 185 metres deep; these holes were drilled on the small copper anomalies (and accompanying copper-bearing outcrop) in the southern part of the property. Results were disappointing. No other data was documented.
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).
