Pigeon Hill Project — Bentley — Ulara Resources
A high-potential gold exploration project covering 2,500 hectares in the Charters Towers district. The tenement is strategically located along the Alex Hill Shear Zone (AHSZ), a major gold-bearing structure associated with multi-million-ounce gold deposits. Surface geochemistry also identifies anomalous copper, cobalt, bismuth and tellurium associated with high-grade gold, supporting potential for polymetallic gold-copper mineralisation.
Bentley sits adjacent to a major gold-bearing shear corridor within the productive Charters Towers Province, combining high-grade surface mineralisation with undrilled structural targets. Multiple high-grade surface occurrences (up to 17 g/t Au) and historical mines confirm a fertile system at surface, while anomalous copper, cobalt, bismuth, tellurium and rare-earth pathfinders point to potential for polymetallic gold-copper mineralisation. Further systematic sampling and drilling are required to test these targets.

Key highlights
Exceptional Gold Grades in Surface Samples
- Rock chips and stream float samples returned up to 17 g/t Au (The Range) and 12 g/t Au (Banana prospect)
- Acacia prospect assays recorded up to 14.77 g/t Au in ferruginous quartz veins
Copper and Polymetallic Pathfinders
- Surface geochemistry identifies anomalous copper (up to 3,920 ppm Cu), cobalt, bismuth and tellurium associated with high-grade gold
- Elevated cerium, lanthanum, yttrium and niobium indicate potential for a broader intrusive and hydrothermal mineral system
Historical Drilling Results (Nearby Deposits)
- Mt Wright (~1 Moz Au) is a deep intrusion-related breccia deposit, with gold hosted in brecciated quartz veins at depths of 300–500m
- The Charters Towers district has deep-seated gold mineralisation extending to over 1,000m depth
Geophysical Anomalies Indicate Potential Deep Gold System
- Strong magnetic and radiometric anomalies align with high-grade surface samples
- Structures in Bentley EPM are similar to nearby multi-million-ounce deposits, supporting deep drilling exploration
Independent Geological Review (Dr Simon Richards, KGS)
- Eastern half of the Pigeon Hill Project, sharing structures with Sophia
- Three prospects identified — The Range, Banana and Acacia — all returning rock chip samples >12 g/t Au
- Sulfide-bearing quartz veins identified at The Range and Banana prospects
- Gold is constrained to intersections between NE-trending structures related to the major Alex Hill Shear and an E-W trending magnetic high
- Secondary structures of the Alex Hill Shear host the nearby 60,000 oz Au Christian Kruk deposit
Regional Geological Context
Bruvel identifies the Alex Hill Shear Zone as a prominent regional structural feature of the Charters Towers district. His broader synthesis explains how gold occurrences can develop on subsidiary structures beside major corridors, and how reactivated fault intersections and dilational zones can channel mineralising fluids.
Relevance to Bentley
This framework provides regional context for the Bentley targeting model described by Dr Simon Richards: gold-bearing surface occurrences associated with intersections between northeast-trending structures related to the Alex Hill Shear Zone and an east–west magnetic-high corridor. It supports investigating structural intersections and alteration with detailed mapping, geophysics and drilling.

The thesis does not assess Bentley, verify its assays or establish a deposit on the tenement. The connection to Bentley is Ulara’s interpretation of regional research alongside its project review, not an endorsement by the thesis author. Grade, continuity and economic significance remain to be established through project-specific exploration.
Project questions
Where is the Bentley project?
Bentley (EPM 28737) is located in Charters Towers, Queensland.
How large is the Bentley tenement?
The Bentley tenement covers 2,500 hectares.
Which commodities does Bentley target?
The project targets Gold, Copper. Its current status is exploration.
Does Bentley have a declared Mineral Resource?
Ulara has not declared a Mineral Resource or Ore Reserve for this project. Historical exploration results and surface samples do not establish average grade, continuity or an economic deposit. Nearby deposits are geological context only, not predictions of results at Ulara's tenements.
