Highlights

  • Strickland reports a maiden 1.2Moz inferred gold resource at the Gradina Deposit.
  • The Rogozna Project inferred resource increases by about 16% to 8.6Moz AuEq.
  • Gradina mineralisation remains open along strike and at depth, with drilling ongoing.

Strickland Metals (ASX:STK)  has announced a maiden Inferred Mineral Resource Estimate (MRE) for the Gradina Deposit at its 100%-owned Rogozna Gold and Base Metals Project in Serbia. The Gradina MRE is estimated at 12 million tonnes grading 3.0g/t gold, equating to 1.2Moz of contained gold. The estimate has been reported in accordance with the JORC Code and represents the first formal resource for the deposit.

The addition of Gradina lifts the total Rogozna Project Inferred Resource from 7.4Moz AuEq to 8.6Moz AuEq, reflecting incremental growth across multiple deposits within the project area.

Resource Assumptions and Methodology
The Gradina resource has been constrained within optimised underground long-hole open stoping shapes. Estimation parameters include a gold price of USD 2,500/oz, metallurgical recovery of 90%, and a cut-off grade of 1.5g/t Au. Mining, processing, site, transport, royalty, and recovery assumptions were applied to ensure the estimate meets the requirement of reasonable prospects for eventual economic extraction.

Deposit Geometry and Grade Distribution
The Gradina Deposit comprises multiple steeply dipping skarn-hosted gold lodes contained within a broader mineralised envelope. Individual zones vary in width from about 3 metres to 30 metres, with an average horizontal width of roughly 11 metres across the resource. The optimised underground stopes extend approximately 800 metres along strike and cover up to 720 metres of vertical extent in parts of the deposit.

Growth Areas and Drilling Activity
Mineralisation at Gradina remains open to the north, south, and at depth, as well as within a central “gap zone” that is currently under-drilled. These areas are scheduled to be the focus of further drilling during 2026. Drilling is continuing across the Rogozna Project, with multiple rigs operating at Gradina and elsewhere within the licence area.

Portfolio Context and Next Milestones
Within the broader Rogozna Project, the 5.3Moz AuEq Shanac Deposit remains the largest contributor to the current resource base. A resource update for Shanac is scheduled for Q1 2026, following the receipt of remaining assay results from the 2025 drill campaign.
