PLANET GREEN METALS EXPANDS SHERATON LAND PACKAGE AND ADVANCES FLAGSHIP EXPLORATION PROGRAM

Planet Green Metals Inc. has expanded its claimholdings surrounding the Sheraton project in late December, 2025, further strengthening its position within a highly prospective copper-zinc-silver volcanogenic massive sulphide (VMS) district located in the Timmins mining camp of Ontario.

The expanded land package increases the company's control over key geological and structural trends interpreted to be favourable for VMS-style mineralization and provides Planet Green with an enhanced footprint for district-scale target generation as exploration advances.

Sheraton project -- flagship VMS project overview and exploration strategy

Following the recent property expansion, Planet Green is advancing a structured, phased exploration strategy designed to progress the Sheraton property toward drill-ready targets using modern exploration techniques and disciplined technical evaluation.

Phase 1: land consolidation and technical data integration (completed/continuing)

As part of the initial phase of work, Planet Green expanded its claimholdings around the core Sheraton project in late December, 2025, and has been expanded by 22 per cent, or 2,752 hectares. In parallel, the company has undertaken the compilation and review of historical geological, geochemical and geophysical data sets available for the property and surrounding area. This work is supporting a preliminary reinterpretation of stratigraphy, structure and known mineralized trends across the expanded land package, which will help guide exploration targeting.

Phase 2: airborne geophysical survey and target generation (planned)

Building on the technical data integration, Planet Green is planning a modern helicopter-borne magnetic and electromagnetic survey over the expanded Sheraton land position. The objective of this program is to identify conductive horizons, alteration zones and structural features that may be associated with VMS-style mineralization. Results from the survey will be integrated with existing data sets to generate, rank and prioritize exploration target areas for follow-up work.

Phase 3: ground-based follow-up and drill target definition (2026)

Subject to the results of the airborne survey, the company plans to conduct ground-based geophysics over priority target areas during 2026. This work is intended to refine geological interpretations and support the definition of high-priority drill targets for an initial drilling program, subject to permitting and results.

Geological setting and mineralization model

The Sheraton property is located within a well-established greenstone belt that hosts numerous base and precious metal occurrences. The geological setting and historical exploration results within the broader area support the presence of VMS-style mineralization, a deposit type known globally for hosting high-grade copper, zinc and silver deposits. The recently expanded land package enhances Planet Green's ability to evaluate two prospective stratigraphic horizons and structural corridors at a district scale.

"The expansion of our claimholdings around Sheraton in late December represents an important step in strengthening our flagship asset," said Jeremy S. Brett, president and chief executive officer of Planet Green Metals. "With a larger and more contiguous land package secured, we are well positioned to apply modern exploration methods to systematically explore our Sheraton project and define high-quality targets for drilling."

Planned exploration milestones

Planet Green expects to provide further updates as exploration activities advance, including details on the planned airborne geophysical survey, the results of target generation efforts and subsequent ground-based follow-up programs.
