The Sitka South occurrence is located on a north-northwest facing slope, north of the Akie River and approximately 5 kilometres east of the Akie (MINFILE 094F 031) developed prospect.
Sulphide mineralization is developed within the Gunsteel Formation, an Upper Devonian sequence of graphitic shales overlying Silurian calcareous siltstones of the Road River Group. The Gunsteel is part of the Upper Devonian to Mississippian Earn Group. Mineralization is typically intercalated within the graphitic shales as fine grained, massive to well-bedded pyrite, sphalerite and galena with appreciable barite and carbonate. Remobilized sulphide mineralization occurs as veinlets in the surrounding lithologies.
The Kechika Trough is bounded to the west and east by carbonates and shallow water clastic rocks of the Cassiar and MacDonald platforms, respectively. The Kechika Trough hosts a sequence of upper Devonian to Mississippian basinal facies clastic sedimentary rocks that is a regional target for SEDEX type zinc-lead-silver deposits, such as the nearby Cardiac Creek (MINFILE 094F 031) deposit. The most favourable horizon at the Akie property is a stratiform barite-sulphide layer, hosted within Upper Devonian shales of the Gunsteel Formation. Mapping on the Akie property has identified a number of northwest-trending panels of Gunsteel Formation shales. These shales have been the target of exploration for SEDEX-type ore deposits since 1978.
Locally, barite with quartz hosts sphalerite and galena mineralization is situated along the thrust contact between siltstones of the Silurian Road River Group and black shales of the Earn Group. A second zone of similar mineralization is located approximately 250 metres southeast of the main zone. Similar mineralization is reported to the northwest across the valley and is covered in the Sitka North occurrence.
Work History
In 2014, ZincX Resources Corp. completed a program of prospecting, geological mapping and geochemical (rock and soil) sampling on the area as the Sitka claims. Six grab samples (2379011 through 2379016) from the main zone yielded from 1.62 to 7.65 per cent zinc, 0.53 to 48.95 per cent lead and 0.5 to 2.0 grams per tonne silver, while two samples (2379009 and 2379010) from the second southeastern zone yielded 7.98 and 4.48 per cent zinc, respectively (Assessment Report 34726).
In 2018, ZincX Resources Corp. completed 6 diamond drill holes, totalling 2163.0 metres, on the Akie property. Drilling tested the; South-East Extension of the Cardiac Creek Zone (MINFILE 094F 031), the North Lead Anomaly, and the first ever drilling of the Sitka occurrence located on the eastern edges of the property.
The following year, ZincX Resources Corp. completed a program of drill core re-sampling from the 2018 drilling program.
