Historical Cat Mountain Drilling Results Notes:
- Results reported above were compiled by
Serengeti Resources from historical analytical certificates appended to assessment reports filed with theMinistry of Energy , Mines and Petroleum Resources. - Interval lengths do not necessarily represent true widths of mineralized zones.
- Individual assay results for gold were capped at 10.0 g/t for compositing purposes.
- EOH: End of hole.
Following the data compilation work, a 3D geological model was developed with Leapfrog Geo in order to determine whether known mineralization may be related to a buried porphyry system. Economic and trace element geochemical data and regional geophysics were combined with the drilling data to determine the significance of historical work with respect to targeting goals. Conclusions resulting from the geological model include:
- Historical results indicate that a porphyry system may exist at
Cat Mountain based on the association of Cu and Au in drill holes, presence of multiple intrusive phases, details of soil geochemistry, and presence of quartz-magnetite ± chalcopyrite-Au veins; - The Bet and Hoffman zones are characterized by moderately to steeply northeast dipping shear structures (the “Bet Shear” and “Hoffman Shear”, respectively) which are dominated by quartz-magnetite ± chalcopyrite-Au veins;
- The Bet Shear is located within a northwest-trending zone of moderate magnetics which occurs between two strongly magnetic lobes, the eastern of which is partially represented by the Hoffman zone;
- The Bet Shear is open along strike to the northwest, defining a newly recognized target area which has not been drill tested;
- There is an association between Au-Cu drill hole intercepts with moderate to low magnetic intensity and magnetic discontinuities;
- Cu, Mo, W, As and Sb in soils, which among other elements may be used to vector toward porphyry systems, define two anomalous zones bisected by the Hoffman Fault and supports a theory of dextral movement along the Fault which is substantiated by magnetics;
- Cu-Mo-W in soil anomalism defines a new target zone (“South Cat”) associated with a dissected magnetic lobe approximately 900 metres south of the Bet zone near the contact with the Hogem Batholith. South Cat has never been drilled and represents a newly recognized target area.

Nova PGE Analysis, Petrography and Targeting
Nova is located in the northern Top Cat property area and is largely overlain by till locally containing angular mineralized magnetite-sulphide bearing “skarn” boulders. The area is characterized by three or more intense magnetic anomalies measuring up to 500m by 800m each. Historical boulder samples assay up to 0.52% Cu, 0.327 g/t Au, 4.4 g/t Ag, 0.071 g/t Pt and 0.498 g/t Pd (BCMEMPR Assessment Report 37051).
Platinum-group element (“PGE”) analysis completed on a magnetite-sulphide “skarn” boulder (“PGE-skarn sample”) collected by Serengeti proximally west of the central magnetic anomaly recently returned 1.39% Cu, 0.69 g/t Au, 6.45 g/t Ag, 0.21 g/t Pt and 1.38 g/t Pd.
Petrographic analysis of the PGE-skarn sample describes a massive skarn dominated by actinolite with lesser magnetite-(ilmenite) and apatite, with a few skeletal interstitial grains of hornblende, scattered patches of chalcopyrite and less abundant bornite altered to covellite. Actinolite is largely interpreted as an alteration product, and when considered with the presence of primary and secondary magnetite associated with copper minerals, suggests magnetic features at Nova may represent the presence of a Cu-Au-PGE bearing pyroxenite or skarn-hosted system.
Soil sampling completed in 2019 identified a strong Cu-Ag anomaly along the fringe of one of the magnetic anomalies, and an interpreted south-southwestern glacial ice flow direction supports the hypothesis that mineralized till boulders may be sourced from “plug”-like magnetic features following the northwestern trend observed at Nova.
