G11 Resources Limited (ASX: G11) has moved decisively in 2025 to expand its footprint across two of Australia’s most prospective mineral belts—Tasmania’s Mt Read Volcanics and the frontier structural corridors of north-western New South Wales (Figure 1). Through the acquisition of Pacific State Metals and further modelling work released later in the year, the Company has unlocked a pipeline of untested gold–copper targets with the scale and geological positioning required for Tier-1 discovery outcomes.

The Business of the Company: Focus – Projects
G11 is now positioned across four complementary project areas (Figure 2):
Sedgwick Bluff (EL11/2025), Tasmania — directly along strike from the Mt Lyell Copper–Gold Mine, sharing the same host lithologies and controlled by the Great Lyell Fault.
Packsaddle (EL9424, EL9442, EL9469), NSW — a 100 km structural corridor with IRG-Cu and Orogenic Au potential anchored by the newly identified Kings Hill magnetic–gravity anomaly.
NW Cobar (EL9470), NSW — multiple bullseye magnetic and IP anomalies prospective for Cobar-style base metals.
Koonenberry Belt (NSW) — 3,300 km² of VMS Cu, Orogenic Au, and Ni–Cu–PGE terrane already hosting a significant Exploration Target at Wilandra.

HIGHLIGHTS 1 — G11 to Acquire New Gold & Copper Projects (13 August 2025)
A Transformational Acquisition of Pacific State Metals
1. Sedgwick Bluff: Untested Extension of a Tier-1 System (Figure 3)
Figure 3: SEDGWICK BLUFF – Tier 1 Cu-Au District in Tasmania (source: G11)
EL11/2025 covers 23 km² immediately along strike from the Mt Lyell Cu–Au district (312 Mt @ 1% Cu & 0.3 g/t Au endowment).
Only 16 historical drillholes, with just four testing the 4 km continuation of the Mt Read Volcanics adjoining the Great Lyell Fault.
Three coherent target zones: West Sedgwick, NE Pyrite Zone, Beatrice (Figure 4).

Large geophysical and geochemical datasets remain unprocessed using modern methods (Figure 5).

2. Packsaddle Project: Kings Hill Anomaly Defined
10 km × 3 km magnetic–gravity high adjacent to the crustal-scale Olepoloko Fault (Figure 6).
Interpreted large granite “heat source” and significant folding, ideal for IRG-Cu and Orogenic Au systems.

3. NW Cobar Project: Large Untested Base Metal System
Multiple discrete magnetic anomalies with semi-coincident IP responses (Figure 7).
Analogous geological setting to the well-endowed Cobar Region.

4. Corporate Terms
G11 to issue 183.2M shares at $0.015 per share.
Acquisition subject to shareholder approval; BDO appointed as Independent Expert.
Post-acquisition share consolidation (10:1) proposed.
HIGHLIGHTS 2 — New Copper–Gold Target Modelled at Sedgwick Bluff (7 November 2025)
Modelled CSAMT Anomaly at Zig Zag Hill Defines a Drill-Ready Target (Figure 8)
1. Zig Zag Hill CSAMT Target Identified
New 3D-modelled CSAMT anomaly located along the Great Lyell Fault, immediately north of Mt Lyell.
Proven CSAMT correlation with Mt Lyell ore zones.
Anomaly lies adjacent to a major fold—ideal for fluid focusing and metal deposition.

2. Priority Forward Work
Drill program planning underway, pending:
Flora & Fauna surveys.
Mineral Resources Tasmania approvals.
Final grant of EL11/2025.
Technical team on site in Tasmania reviewing access and contractor options.
3. Additional Targets Being Assessed
Further review is ongoing at the NE Pyrite Zone, reinforcing the emerging multi-target nature of Sedgwick Bluff.
About the Project
Sedgwick Bluff (Tasmania)
Located within the Mt Read Volcanics, one of Australia’s premier multi-commodity belts.
The Great Lyell Fault is the primary control on Mt Lyell mineralisation, and the same structure continues directly into EL11/2025.
Historical exploration focused elsewhere, leaving the northern strike largely untouched despite identical geology.
Packsaddle (NSW)
A major continental-margin structural corridor.
Kings Hill hosts “Tier-1 scale” coincident magnetic, gravity, and structural complexity signatures.
Cover depth likely <100 m, improving drill economics.
NW Cobar (NSW)
Targets aligned with Cobar-style systems: discrete magnetic cores, IP chargeability, and favourable basement volcanics.
Near-Term Milestones to Watch
EL11/2025 grant finalisation in Tasmania.
Flora & Fauna surveys followed by drill permitting at Zig Zag Hill.
Processing & reinterpretation of 70 years of historical Sedgwick Bluff datasets.
Drill targeting refinement at Kings Hill, Packsaddle.
Planned maiden drilling across Sedgwick Bluff and Packsaddle in 2026.
How Samso Understands the Investment Memo for the Company
G11’s acquisition footprint aligns with structurally controlled, large-system deposit types known to host multi-million-ounce and multi-million-tonne resources.
Sedgwick Bluff represents a unique structural continuation of Mt Lyell—rarely does a company gain exposure to such a setting with so little modern drilling.
Packsaddle and NW Cobar provide scale, optionality, and multi-target diversity across a region traditionally under-explored due to cover.
The strategic consolidation simplifies future exploration budgeting and positions the Company to chase Tier-1 outcomes.
Samso Concluding Comments
G11 is clearly positioning itself for scale, not incremental gains. The Company’s stated commitment to large intrusive and orogenic systems is consistent with the geological signatures emerging from Sedgwick Bluff and Packsaddle.
From an investment perspective, the key attraction lies in the structural control of the mineral systems. The Great Lyell Fault is one of the most mineralised structures in G11 is clearly positioning itself for scale, not incremental gains. The Company’s stated commitment to large intrusive and orogenic systems is consistent with the geological signatures emerging from Sedgwick Bluff and Packsaddle.
Tasmania, and having a 4 km untested continuation, is a geological opportunity rarely seen in modern Australian exploration. The fact that historical work was constrained by ownership priorities—not prospectivity—creates an opening for G11 that is unlikely to be repeated.
Packsaddle, specifically the Kings Hill anomaly, stands out as a frontier target with all the hallmarks of a large IRG-Cu or Orogenic Au system. This is a geological setting where cover has masked significant potential, and the recent gravity reinterpretation provides strong evidence of a substantial intrusive heat source. Such alignments between structure, magnetics, gravity, and basement architecture often precede major discoveries.
The NW Cobar Project further strengthens the regional strategy. While Sedgwick Bluff and Packsaddle may carry more Tier-1 upside, NW Cobar fits neatly into G11’s diversification approach by adding a third structurally controlled system with historical under-testing. In modern exploration, multiple bets across complementary geological provinces significantly improve discovery probability.
Taken together, G11 has transitioned into a company with genuine exposure to large-scale, system-level exploration—exactly the type of profile that historically leads to transformative drilling outcomes. Investors should monitor the pace of permitting, ongoing data integration, and the first drill program at Zig Zag Hill as the major value inflection points heading into 2026.
