Slide 3: Background: What is a porphyry deposit?
Background: What is a porphyry deposit? • Porphyry is primarily a geological rock texture description. • The term has been adopted to describe large tonnage, low grade deposits, usually with copper, gold, molybdenum and silver mineralisation. These are often associated with porphyritic intrusive roc
Slide 4: Background: The Macquarie Arc
Background: The Macquarie Arc • The Macquarie Arc within the Central West of NSW is a long-lived Ordovician to Early Silurian aged (480 – 400 million years from present) oceanic island arc. • It is remarkably well preserved, gently folded volcanic and intrusive sequence, often bounded by major north

Slide 6: Boda Geological Model
Boda Geological Model • Through extensive drilling of the area, Alkane has developed a conceptual geological model for the Boda – Kaiser intrusive and alteration system. • The host rocks are shallow to moderately west dipping sequence of shoshonitic basaltic andesite lavas with lesser volcaniclastic
Slide 7: Boda-Kaiser Deposits
Boda-Kaiser Deposits • To the end of October 2023, Alkane has completed approximately 200,000 metres of drilling within the Boda area. • Drilling has defined more than 3km of continuous calc-potassic alteration with Au-Cu mineralisation from Kaiser to Boda 2-3. • Potassic pyrite zone (gold rich) occ
