Strickland Metals (ASX: STK) has delivered a maiden Inferred Mineral Resource Estimate of 1.2 million ounces of gold for the Gradina deposit at its Rogozna project in Serbia.
This initial estimate has contributed to a broader 16% increase in the total Rogozna resource base, which now stands at 8.6Moz of gold equivalent across four deposits.
The Gradina estimate comprises 12 million tonnes at 3.0 grams per tonne gold when reported above a 1.5g/t cut-off and constrained within optimised underground stoping shapes, with mineralisation extending along an 800-metre drill-defined corridor featuring consistent widths and strong continuity.
The system averages around 3,100oz of gold per vertical metre across the modelled 180m interval, highlighting the grade strength observed to date, with Strickland reporting a discovery cost of $US10/oz.
Managing director Paul L’Herpiniere said the result “reinforces the quality and scale of the Rogozna project” as drilling continues across multiple targets.
Underground Development Supported
The Gradina model incorporates nine mineralised domains defined by gold assays above 1.0g/t and controlled by skarn and intrusive geometries across a footprint measuring around 400m across strike and 800m along strike, presenting a coherent platform for future underground evaluation.
The dataset incorporates 29,475m of drilling from 43 holes completed by current and previous project owners, with sampling in half-core intervals and most samples collected on 2m-spacing to maintain consistency.
The wider Rogozna project now hosts 8.6Moz of gold equivalent across the Shanac, Medenovac, Copper Canyon, and Gradina deposits.
Shanac remains the largest contributor with 5.3Moz gold equivalent at an average grade of 1.1g/t, followed by Medenovac’s 1.28Moz at 1.9g/t, while Copper Canyon adds 0.81Moz at 0.9g/t.
Across all deposits, the resource also contains 321,000t of copper, 32.3Moz of silver, 383,000t of lead, and 830,000t of zinc.
Forward Work Program Underway
Two rigs are currently drilling within the Gradina gap zone to extend mineralisation and refine continuity, while three additional rigs are undertaking discovery drilling across the broader project as part of a multi-deposit growth strategy.
Strickland – which attributes the ongoing growth at Rogozna to extensive drilling, modelling, and geochemical and geophysical programs it has undertaken since 2024 – expects to begin resource modelling for the Shanac deposit once final 2025 assay results are received.
Field operations are expected to pause in late December ahead of drilling recommencing in February with a larger rig fleet planned.
The company expects to complate an updated Shanac Mineral Resource Estimate in the first quarter of 2026.
