Slide 6: NMPP Geology / Structural / Intrusive Summary
NMPP Geology / Structural / Intrusive Summary Boda – Kaiser located at the intersection of the Arc parallel Nindethana Thrust and northwest ‘Dubbo’ transverse corridor. Other north-south thrust structures offset the belt to the west (Macquarie Thrust). Dilationary intersection and offset provides en
Slide 7: NMPP Targets
NMPP Targets Current Targets 15km northwest trending structural corridor with multiple ‘fertile’ alkalic (monzonite) intrusive complexes. Finns Crossing – Murga prospect aeromag target (skarn like characteristics) and separate strong IP chargeablity anomaly. Extensive argillic lithocap. Surface floa
Slide 8: Kaiser - Boda Corridor
Kaiser - Boda Corridor • Historic gold – copper outcropping workings at Kaiser. • Drilling (1960s – 1990s) targeted Kaiser, identified a small ‘’high grade’ Au-Cu body within extensively altered and mineralised Ordovician volcanics. • Alkane’s regional work confirmed a target corridor 3- 5km in leng
Slide 9: Boda Drilling – Discovery Section
Boda Drilling – Discovery Section • Initial core testing of anomalous gold results in an RC hole which drilled an Au-Cu elevated soil. Also mapped surface alteration Sections on the flanks of a weak aeromagnetic anomaly. • KSDD003 and KSDD005 returned significant Au-Cu mineralisation within clearly

Slide 12: Boda – Metal Zonation
Boda – Metal Zonation • Alteration at Boda is clearly zoned from outer propylitic, propylitic to inner potassic / calc potassic. • Copper tends be focussed Section within the inner potassic, while gold is common throughout. • Recent drilling has demonstrated other metals such as molybdenum and pathf
Slide 13: Boda Two - KSDD022; 030; KSRC036
Boda Two - KSDD022; 030; KSRC036 • The Boda Two target is marked by a strong IP chargeability and resistivity anomaly. • Drill testing to date has intersected a large Au rich pyrite shell comprising stringers and aggregates of pyrite within a sequence of propylitic altered basaltic andesites. • Anom
Slide 14: Kaiser (Duke) - KSDD027 (2021)
Kaiser (Duke) - KSDD027 (2021) • KSDD027 confirmed a broad mineralised alteration envelope to the east, in addition to that at Kaiser. • The eastern (Duke) zone demonstrates near surface grades over 250m width with a strike length of over 800m, open along strike and at depth. Kaiser – Boda Porphyry
Slide 15: NMPP Porphyry Model and Boda-Kaiser Mineralisation
NMPP Porphyry Model and Boda-Kaiser Mineralisation Key Observations to Date The host sequence is evolved basalt to andesite, flat lying volcaniclastics and lavas, cut by near vertical monzonitic bodies with at least three separate monzonite intrusive ages. Lithogeochemistry and age-dating clearly pl
