Overview

Property

Approximately4,220ha

Location 

Omineca Mining Division of north-central British Columbia, Canada. 6km west of the Omenica Access road, and 45km south-southeast of Centerra's Kemess project 

Target Summary

The project lies within Mesozoic volcanic rocks of the eastern Stikine Terrane which host most of the known porphyry systems in the region. Reconnaissance mapping and sampling in 2018 yielded encouraging results, including three samples with high Cu (up to 57% Cu) and Ag (up to 670g/t Ag) from a quartz – Cu-sulphide-oxide vein stockwork zone hosted within hematized mafic agglomerates

Project Summary

The Arjay property is located approximately 45 kilometres south-southeast of Centerra Gold’s Kemess project within the Omineca region of north-central British Columbia. The property occurs within a wedge of basaltic rocks of the Upper Triassic Takla Group intruded by Early Jurassic quartz-diorite plutons. Reconnaissance mapping and sampling yielded encouraging results, including three samples with locally highly elevated copper and silver from a quartz – copper-sulphide-oxide vein stockwork zone hosted within hematized mafic agglomerates of the upper Takla Group, likely representing the Takla – Hazelton unconformity zone. A disrupted highly magnetic zone occurs at Arjay which may represent hydrothermal alteration of magnetite-bearing volcanic host rocks, possibly associated with the observed mineralization.

2019 Exploration

Serengeti has expanded the Arjay and West Goldway claim group to approximately 4,220ha. The project lies within Mesozoic volcanic rocks of the eastern Stikine Terrane which host most of the porphyry systems in the region.

Mapping and sampling at Arjay in 2018 identified strong Cu-Ag mineralization (up to 57.3% Cu and 671 g/t Ag; see press release dated November 29th, 2018). This summer’s work found that over much of the property area high-grade quartz-carbonate shear veins occur, mainly within oxidized fragmental volcanics of the Moosevale Formation.

Disseminated Cu-Au-Ag mineralization hosted within aplite and andesite porphyry dykes, assayed from trace up to 7.55% Cu, 0.64 g/t Au and 203.0 g/t Ag in sample CV015. The high-grade mineralization may be driven by a larger hydrothermal system associated with intrusive rocks and quartz-sericite-pyrite (“QSP”) alteration outcropping in the northeastern portion of the property.  Wide-spaced soil sampling results from this area indicate a Cu-Mo anomaly with peripheral Zn signature which is typical of porphyry systems in the region.

Company geologists completed a mapping and sampling program at Arjay, collecting 65 rock samples and 68 soil samples on a 250m grid. Two reconnaissance induced-polarization (“IP”) lines were also conducted at Arjay-Goldway, and three additional IP lines were completed at Atty after drilling had finished. Highlights of the sampling program at Arjay include:

Geophysics

In August, the high grade assay results were followed up with a 3km IP line. The line ran from the high-grade shear vein areas into stratigraphically-lower Savage Mountain rocks in the northeastern part of the property. These rocks host QSP alteration and anomalous soil geochemistry. The IP survey found a strong chargeability response below valley fill, associated with an airborne magnetic low and coincident K/Th radiometric high in an area of anomalous Cu-Mo-Zn geochemistry.

Serengeti also completed a 5km IP line over an aeromagnetic high associated with a soil anomaly identified in 2018 sampling at the West Goldway project. The 2019 IP line picked up a strong chargeability and flanking resistivity anomaly below valley cover, coincident with the aeromagnetic high and flanking anomalous soil geochemistry.
