Favorable locations in key Macquarie Arc volcanic belts
Advanced exploration stage &/or host large footprints
New discovery at Southern Extension Zone (Trundle project)

Trundle: Brownfield setting to Northparkes

Western side of the Northparkes Igneous Complex
Previously 2208 holes for 61,146m, only 11 >250m depth

Observations & learnings: Trundle Park prospect

Significantly improved geological understanding has both guided and justified deeper drilling, resulting in the discovery of:

  • Two new porphyry intrusion Zones (Central and Eastern) and the Southern Extension Zone (in the last quarter)
  • Mineralisation footprint expanded from 700m to >1300m in strike length (open) and from <30m to >800m depth (open)
  • Copper-gold mineralisation and alteration hosted by volcaniclastic and limestone units and also intrusions along low magnetic response zones, trending from SW to NE within an interpreted structural zone, comprising:
    • Overlying volcaniclastic rocks adjacent to skarns with +/- Kfeldspar, hematite, epidote, quartz, pyrite and traces of chalcopyrite and bornite along veinlets or as blebs.
    • Prograde skarn replaces volcaniclastic units with banded and massive textured intervals with garnet, clinopyroxene, magnetite and disseminated pyrite and chalcopyrite
    • Retrograde skarn (overprints) with magnetite, hematite, orthoclase, epidote, quartz, carbonate, pyrite and chalcopyrite.
    • Breccia zones along the margins of monzodiorite contain gold with Kfeldspar, hematite, quartz, pyrite with gold
    • Quartz veins with traces of molybdenite and chalcopyrite cut both monzonite and quartz-monzonite porphyry intrusions
  • Propylitic alteration (epidote) is widely distributed (not useful as a visual vector towards copper-gold)
  • Higher temperature alteration minerals: Kfeldspar and prograde garnet skarn helping to vector towards copper-gold
  • Geological review (internal / external), 3D modelling (structural / geological architecture) and drilling of Trundle area ongoing •
  • The skarn mineralisation is significant, BUT our primary target is a high-grade copper-gold porphyry system!

Trundle Project background

The Trundle Project is located in the Junee-Narromine volcanic belt of the Macquarie Arc, less than 30km from the mill at the Northparkes mines in a brownfield setting within the westerly rift separated part of the Northparkes Igneous Complex (“NIC”). The NIC hosts a mineral endowment of approximately 24Moz AuEq (at 0.6% Cu and 0.2g/t Au) and is Australia’s second largest porphyry mine comprising of 22 discoveries, 9 of which with positive economics.

The Trundle Project includes one single license covering 167km2 and was secured by Kincora in the March 2020 agreement with RareX Limited (“REE” on the ASX). Kincora is the operator, holds a 65% interest in the Trundle Project and is the sole funder until a positive scoping study is delivered at which time a fund or dilute joint venture will be formed.
