New Structural Framework Reveals Major Gold-Copper Porphyry Potential at Rogozna
Strickland Metals (ASX: STK) has unveiled a significant breakthrough at its 7.4Moz AuEq Rogozna Project in Serbia, identifying multiple new porphyry targets through an innovative structural framework approach that could substantially expand the company's resource base.
Gravity Survey Unlocks New Discovery Pathway
A newly completed gravity survey has revealed a comprehensive structural architecture across the Rogozna Project, highlighting three key mineralisation-controlling structures that traverse the entire project area. This structural understanding represents a major step forward in focusing exploration efforts, particularly for porphyry-style deposits in areas masked by post-mineral volcanic cover.
The survey results, combined with existing Induced Polarization (IP) and Remanent Magnetic data, have delineated multiple circular anomalies interpreted as potential magmatic intrusive centers – prime targets for porphyry exploration. These findings establish a clear roadmap for discovering additional large-scale mineral systems beyond the company's already impressive resource base.
"The recently completed gravity survey has delivered some exciting results," said Paul L'Herpiniere, Strickland's Managing Director. "This shows just how fertile a geological environment we have on our hands at Rogozna, with the potential to discover multiple large-scale mineral systems in addition to the known skarn-hosted deposits."
Building on an Already Substantial Resource
The new targets complement Strickland's existing 7.4Moz AuEq resource at Rogozna, which includes:
| Deposit | Resource (Mt) | AuEq (g/t) | Gold (Moz) | Copper (kt) | Silver (Moz) | Lead (kt) | Zinc (kt) |
|---|---|---|---|---|---|---|---|
| Shanac | 150 | 1.1 | 3.09 | 180 | 28.0 | 360 | 510 |
| Medenovac | 21 | 1.9 | 0.52 | 57 | 4.3 | 23 | 320 |
| Copper Canyon | 28 | 0.9 | 0.36 | 84 | – | – | – |
| Total | 199 | 1.2 | 3.97 | 320 | 32.2 | 380 | 830 |
Previous drilling at the Jezerska Reka prospect intercepted extensive porphyry-related veining with associated gold mineralisation, including 493.0m @ 0.14g/t Au and 92.0m @ 0.40g/t Au. These results suggested the drilling was positioned distal to the center of a mineralised magmatic hydrothermal system, with the new geophysical data now providing clearer targeting for the potential center of this system.
Understanding Porphyry Systems
Porphyry copper-gold deposits represent some of the world's largest and most valuable mineral resources. These large-scale magmatic-hydrothermal systems typically form at convergent plate boundaries and are characterised by extensive volumes of hydrothermally altered rock containing disseminated copper and gold mineralisation.
Porphyry deposits are notable for their substantial size and relatively consistent grades. They often contain hundreds of millions to billions of tonnes of ore, with copper grades typically ranging from 0.2% to 1% and gold grades from 0.1 to 1 g/t. While these grades might appear low, the enormous volume of mineralised material makes these deposits economically viable and highly sought-after exploration targets.
The circular gravity anomalies identified at Rogozna are particularly significant as they likely represent the dense intrusive centers that drive these mineralising systems. In porphyry environments, structural controls – like those identified in the new framework – are crucial for focusing mineralising fluids and creating economic deposits.
Key characteristics of porphyry systems include:
- Large, multi-phase intrusive complexes
- Extensive hydrothermal alteration halos
- Systematic metal zonation patterns
- Strong structural controls on mineralisation
- Association with convergent plate boundaries
The Western Tethyan Belt, where Rogozna is located, is known for hosting numerous world-class porphyry deposits, making the structural framework identified at Rogozna particularly relevant for targeted exploration.
Strategic Follow-Up Program
Strickland is moving quickly to capitalise on these findings with a Magnetotelluric (MT) survey planned to commence in the coming weeks. This deep-penetrating geophysical technique will help "see" through the volcanic cover to better define the underlying structural architecture, refining drill targets for testing in late 2025.
"The gravity survey will be followed up with a Magnetotelluric Survey commencing in the coming weeks, which will enable us to 'see' through cover into the underlying structural architecture of the area, helping to refine the locations of the next round of drilling to test some of these target areas," L'Herpiniere explained.
The company's dual-track exploration approach includes both testing these new porphyry targets and continuing its ongoing 50,000m drilling campaign focused on growing the existing resource base at known skarn-hosted deposits like Shanac, Gradina and Medenovac.
Financial Strength to Drive Discovery
With $52.4 million in cash and liquid assets as of June 30, 2025, Strickland is well-funded to pursue its ambitious exploration program. This financial strength allows the company to simultaneously advance multiple exploration fronts across the Rogozna Project.
Why Investors Should Watch Strickland
Strickland presents a compelling investment case for several key reasons:
-
Resource Growth Potential: The company's existing 7.4Moz AuEq resource provides a solid foundation, with multiple avenues to significantly expand this resource base.
-
New Discovery Opportunities: The newly defined porphyry targets represent potential company-making discoveries, especially given the substantial size of porphyry deposits globally.
-
Systematic Exploration Approach: Strickland's methodical application of advanced geophysical techniques demonstrates a sophisticated approach to unlocking the full potential of the Rogozna Project.
-
Financial Capacity: With over $50 million in the bank, the company is fully funded to execute its exploration programs without near-term capital constraints.
-
Jurisdiction Advantage: Serbia sits within the prolific Western Tethyan Belt, home to numerous world-class porphyry and epithermal deposits, yet remains underexplored relative to other mining regions.
The new structural framework at Rogozna represents a pivotal development in Strickland's exploration strategy, potentially unlocking multiple new large-scale mineral systems beneath cover. With each survey refining the company's understanding of this fertile geological environment, Strickland is positioned for potential significant discoveries that could transform the scale of the already substantial Rogozna Project.
