Overview

The Nogurbek geology consists of Ordovician, Carboniferous, and Devonian volcanic, volcaniclastic, and sedimentary rocks into which several dioritic intrusions have been emplaced. The property is cut by three large, northwest-southeast striking regional faults, which have brough together several different litho-tectonic terranes, each host a distinct style of mineralization, including:

• Cu-Au porphyry mineralization
• Orthomagmatic sulphides Ni-Cu ± Co, PGE mineralization
• Au-rich VHMS (Cu-Au-Ag-Zn-Pb)

Akkuduk Target

Historic work identified Cu-Au porphyry mineralization associated with quartz diorites and granodiorites emplaced into basalts, tuffs and andesites. Historic drilling conducted in the 1990’s returned significant Au-Cu mineralization, including:

• 21m @ 1.01 g/t Au
• 23.5m @ 0.91 g/t Au
• 40.5m @ 1.19 g/t Au
• 56m @ 0.58 g/t Au
• 39.5m @ 0.48 g/t Au
• 30.5 m @ 1.65 g/t Au
• 19.8 m @ 1.2 g/t Au
• 15.9m @ 1.52 g/t Au
• 30.2m @ 1.07 g/t Au
• 10.7m @ 1.42% Cu
• 17.0m @ 0.24% Cu

Arras Minerals believe that the Akkuduk Target hosts a potentially significant Cu-Au porphyry deposit.

VHMS Targets

Mapping and sampling conducted by Arras Geologists have identified several areas of hydrothermal alteration related to faults zones and fault intersections, where grab sampling from historic trenches returned grades up to 5 g/t Au, 810 g/t Ag, 1.3% Pb and 6.45% Cu.

Ni-Sulphides Target

Soil sampling conducted in 2022 identified a large Ni soil anomaly that coincides with a major magnetic. Initial mapping identified a large mafic intrusion in this area located within a major lithospheric scale fault, suggesting that the property may host magmatic Ni-Cu- (Co, PGE) deposits like the Maksut mine located 320km to the SE (43.5MT @ 0.41% Cu, 0.33% Ni)
