Drilling Update from Sinjakovo Project
KEY SUMMARY
Initial drilling at Erak Prospect has intersected shallow ferruginous breccia, with visible secondary minerals after primary tetrahedrite (Au-Ag rich copper-antimony sulphosalt). The results are expected within four weeks.
Mineralisation was thickest in the third (last) drillhole (ERDD003), intersecting ferruginous breccia 7.1m wide (near true thickness) from 26.2m drilling depth.
Mineralised breccia is still open along strike and depth. Further drilling is planned to continue testing the shallow oxide minerals along strike and the primary sulphide mineralisation at depth.

PROSPECT NAME Erak Prospect Sinjakovo Project, 100% owned |
BEST TRENCH RESULT 61m @ 1.5g/t Au[1] Trench SICH003 from 792m |
GOLD ON SURFACE 7.9 g/t Au[2] Rock-chip, recently identified |
SILVER ON SURFACE 2,070 g/t Ag(2) Rock-chip, recently identified |
ANNOUNCEMENT DETAILS
13th April 2026 – Yugo Metals Limited (ASX:YUG) (“Yugo Metals” or “the Company”) is pleased to report the visual observations from the first-ever drilling at gold-silver-copper-antimony Erak Prospect at its 100% Sinjakovo Project in Bosnia and Herzegovina.
Three diamond drillholes have been completed at Erak (Au-Ag-Cu-Sb) Prospect to date. The total length of drilling is 240m.
Drillholes were designed to test a down-dip extension of a mineral system previously tested with the trench SICH003, returning 21m @ 1.32g/t AuEq(3); an additional mineralised zone was identified some 400m to the east (with trench result of 61m @ 1.5g/t Au[3]) that is yet to be initially drill-tested.
The reported drilling has intersected ferruginous breccia with moderate disseminated polymetallic mineralisation. Observed mineralisation comprises mineral assemblage: barite, hematite, goethite, limonite malachite, stibnite and other – indicative of primary sulphidic barite-pyrite-tetrahedrite mineralisation at depth. The skeletal remnants of sulphides suggest original 1-10mm size of sulphidic grains[4].
All assays are pending and are expected within 4 weeks. Mineralisation is open along strike and depth. Further drilling is being designed to test the system along the strike and depth.

CEO COMMENTARY
Petar Tomašević Executive Director CEO
“We are very pleased by the progress of our initial diamond drilling program at the Erak Prospect. The initial three drillholes have successfully intersected an encouraging width of the targeted breccia-hosted mineral system. Importantly, the drilling has confirmed the presence of minerals indicative of a robust sulphidic system at depth.
Assay results from the current drilling are expected within four weeks. With the gold-silver-copper-antimony mineralisation remaining open along strike and at depth, our team is now designing the next phase of drilling to systematically test both the down‑dip extensions and the broader strike potential of the system. We look forward to updating shareholders as results become available.”
NEAR - TERM OUTLOOK
Planned Next Steps
- Receipt of assays from drilling completed to date
- Applying for new drill permits
- Expanding the resource potential with extensional drilling along strike and dip
- Initiating drilling at a new target 400m to the east, with previous trench results of 61m @ 1.5g/t gold.

FORWARD LOOKING STATEMENTS
This announcement contains forward-looking statements which involve several risks and/or uncertainties. These forward-looking statements are expressed in good faith and are believed to have a reasonable basis.

No obligation is assumed to update forward-looking statements if these beliefs, opinions and/or estimates should change and/or to reflect other.
Note: polymetallic mineralisation is encountered at localities throughout the project area. For easier reporting and comparison of assay results, figures in this report sometimes include the “gold equivalent” results. This is a simpler reporting measure that combines the results from gold, silver, copper, lead, antimony and zinc (normalised by their market prices and the expected metallurgical recoveries).
