Peel Mining Limited (ASX: PEX) announced on 21 April 2026 that Exploration Licence EL9887 has been granted in the Cobar Basin of New South Wales, covering the newly identified Thunderstruck prospect. With a Land Access Agreement already executed with the key landholder, Peel is now fast-tracking drilling to test a compelling combination of a pipe-like magnetic anomaly (approximately 250m x 400m x 100m) commencing at ~100m depth, directly beneath an intense Thallium-Arsenic-Antimony (Tl-As-Sb) pathfinder elements geochemical plume intersected in 2023 drilling. Initial drill testing is proposed in the coming weeks, subject to regulatory approval.

For a Cobar Basin explorer, a fresh tenement grant over a target that combines a strong magnetic anomaly, a pathfinder geochemical plume, proximity to regional-scale faults, and land access already in place is about as clean a setup as exploration offers. Thunderstruck is the Company's next near-term drill catalyst.

Announcement Overview

EL9887 covers the Thunderstruck prospect, which was identified during Peel's review of open-file geological data within the broader Cobar Basin. That review led to the pegging of an Exploration Licence Application over the previously vacant area. The grant of EL9887 now gives Peel the right to explore, and with land access simultaneously secured, there is no procedural obstacle to a rapid move into drilling.

Peel is preparing a fast-tracked exploration program and seeking regulatory approvals for initial drill testing in the coming weeks — a compressed timeline that signals both the Company's conviction in the target and the maturity of the data package supporting it.

Company Background: Peel Mining Limited

Peel Mining Limited (ASX: PEX) is a NSW-focused base and precious metals explorer headquartered in West Perth. The Company has an established history of exploration in the Cobar Basin, one of Australia's most prolific base and precious metals provinces.

Detailed Analysis

Why Thunderstruck Matters

The Thunderstruck target brings together four independently encouraging signals that rarely stack this cleanly: (1) a strong, modelled east-dipping pipe-like magnetic anomaly; (2) surface lag geochemistry anomalism in Pb-Sb-Mo adjacent to the magnetic body; (3) a 2023 sulphide (pyrite)-rich drill intercept at shallow depth exhibiting an exceptionally strong Tl-As-Sb pathfinder elements signature and elevated Pb-Zn; and (4) favourable sedimentary/limestone host geology with sulphide development at the contact zone. Each of these signals is typically considered consistent with a Cobar-style base metal sulphide system.

Structural Positioning

Thunderstruck sits near the intersection of the regional-scale Jackermaroo and Sandy Creek Faults — the type of structural intersection that historically controls mineralised fluid focus in Cobar-style systems. Combined with the pipe-like geometry of the magnetic body, this structural setting is a classic Cobar target architecture.

Execution Timeline

Land access is in place, regulatory approvals are being sought, and initial drilling is planned within weeks. Cobar Basin drilling programs often face delays from heritage, landholder negotiation or licensing processes, so having those derisked upfront is a meaningful operational advantage.

Strategic Significance

Thunderstruck adds a high-conviction, drill-ready target to Peel's exploration portfolio in a province where the Company has strong technical knowledge. A successful drill test could transform the target from conceptual to resource-definition trajectory; an unsuccessful test provides data to refocus effort elsewhere in the district.

Market and Investor Impact

For PEX holders, the combination of fresh ground, strong geophysical and geochemical signals, secured land access and imminent drilling typically produces short-term rerating potential, particularly given Cobar Basin targets' ability to deliver rapid grade-tonnage upside when systems are intersected.

What This Means for Investors

Near-term catalysts are tightly timed: regulatory approvals, drill mobilisation, and first assay results. Investors should monitor announcements on drill commencement and assay receipt.

Risks and Opportunities

Risks

  • Exploration risk: target signatures do not guarantee economic mineralisation.
  • Regulatory risk: drilling requires approvals, and timing can slip.
  • Commodity price risk: base metal pricing influences project economics even if mineralisation is confirmed.
  • Balance sheet: ongoing drilling funded from working capital may require future capital raises.

Opportunities

  • Pipe-like magnetic body at drill-testable depth (~100m).
  • Strong Tl-As-Sb pathfinder signature intersected previously.
  • Favourable host geology and structural setting.
  • Land access and tenure both already secured.

Key Takeaways

  • EL9887 granted over Thunderstruck prospect in the Cobar Basin NSW.
  • Magnetic body modelled at 250m strike x 100m width x 400m vertical from ~100m depth.
  • Strong Tl-As-Sb geochemical plume from 2023 drilling directly above magnetic target.
  • Land access executed; drilling proposed within weeks.

Bottom Line

Peel Mining has assembled a high-conviction Cobar target with tenure, land access, geophysics, geochemistry and geology all aligned. The drill bit will decide what Thunderstruck becomes.
