Cautionary statement

Includes inferred resources. There is a lower level of geological confidence associated with Inferred Mineral Resources than with Indicated or Measured Mineral Resources. There is no certainty that further exploration work will result in the conversion of Inferred Mineral Resources to Indicated or Measured Mineral Resources, or that the Production Target itself, or the forecast financial information derived from it, will be realised.

Pivotal Metals

A copper development project and a district-scale exploration pipeline, both in Québec.

Pivotal Metals (ASX: PVT) is the 100% owner of the Horden Lake copper-nickel-gold-silver-PGM-cobalt project in Québec, Canada, and holds the Belleterre exploration portfolio on the Belleterre-Angliers Greenstone Belt. Horden Lake’s maiden Scoping Study (September 2026) outlines a conventional open-pit and flotation development based on part of its JORC Mineral Resource. The Company’s focus is now on converting and growing that resource, advancing engineering, environmental baseline work and stakeholder engagement, and assessing funding opportunities — in parallel with systematic exploration at Belleterre.

Investor Presentation - Horden Lake Scoping Study

Pivotal Metals released an investor presentation summarising the results of its Scoping Study for the 100%-owned Horden Lake copper project in Quebec, Canada, reporting a post-tax NPV7 of ~A$920M, ~49% post-tax IRR and a 1.3 year payback, alongside an update on exploration progress at its Belleterre projects. The Scoping Study is a preliminary, order-of-magnitude assessment (AACE Class 5, -30/+50% accuracy) that includes Inferred Mineral Resources and is not sufficient to support Ore Reserve estimation.

Horden Lake Economics Confirm Strong Copper Development Case

Pivotal Metals released a maiden Scoping Study (AACE Class 5, -30%/+50% accuracy) for its 100%-owned Horden Lake Cu-Ni-Au-Ag project in Québec, Canada, outlining a base-case post-tax NPV7 of A$920 million and 49% IRR (A$1,343 million/63% at spot pricing), with capital payback of 1.3 years from first ore and pre-production capital of A$411 million. The study is based on the July 2026 Mineral Resource Estimate of 52 Mt at 1.05% CuEq and envisages an 11-year open-pit, truck-and-shovel operation producing copper and nickel concentrates, with the company noting more than A$400 million in additional funding will be required to advance development and cautioning that the results are preliminary and not sufficient to support Ore Reserve estimation.

Downhole EM Refines Shanty Lake Conductor

Pivotal Metals completed drill hole 26-PIV-08 at the Shanty Lake Cu-Ni target within its 100%-owned Belleterre Project in Québec, which intersected sulphide mineralisation but returned no significant assay results. A subsequent downhole electromagnetic survey identified a 350x140m, 200-750 Siemens conductive plate interpreted to lie above the drill hole trajectory, leaving the refined target untested. Drilling of 988m in five holes at Lorraine Mine East is complete with assays pending.

Bambino Deal Expands High-Grade Cu-Ni-PGM at Belleterre

Pivotal Metals has entered an option agreement to acquire 100% of the 57-claim, 3,320-hectare Bambino Project in Québec, which surrounds its existing Delphi Patry and Zullo occurrences and consolidates the Midrim-Zullo trend of high-grade Cu-Ni-PGM occurrences. Consideration is C$125,000 cash, 9,615,000 shares and $500,000 of exploration work over three years, with a 2.0% NSR retained by the vendors. Surface geophysics is planned from September ahead of possible drilling in the fourth quarter, while drilling continues at the Lorraine mine.

Major Copper Resource Growth at Horden Lake

Pivotal Metals reported a major increase in the Mineral Resource Estimate at its Horden Lake copper-nickel-gold-PGM-cobalt project in Quebec, Canada, growing the total resource by 42% to 52 Mt at 1.05% CuEq (549 kt CuEq) and the pit-constrained open pit resource by 46% to 45 Mt at 1.07% CuEq (485 kt CuEq). The growth was driven by drilling geophysical EM conductors, and the deposit remains open along strike and at depth with further undrilled conductive targets identified. The updated MRE is intended to underpin a Scoping Study planned for Q3 2026.
