In parallel, the Company is advancing permitting activities to convert the Brevene exploration licence to a mining concession under Bulgaria’s well-defined permitting framework.
asserted
Company → advance → framework
- Encouraging metallurgical testwork results: Preliminary metallurgical testwork indicates that Brevene Porphyry South mineralization is amenable to conventional rougher-cleaner flotation, with open-cycle tests producing copper-gold concentrates at grades ranging between 10% to 25% for copper and 12 g/t to 20 g/t gold.

The results demonstrate the significant vertical extent (over 1,000 metres) of Au-Cu mineralization within the Brevene Porphyry South system.
asserted
results → demonstrate → system
The mineralization is hosted by a strongly altered porphyritic intrusion, where magnetite-chlorite-sericite alteration overprints earlier potassic alteration, and characterized by quartz-dominated stockwork and sheeted veins, locally with silica flooding, hosting abundant chalcopyrite-pyrite mineralization.

alteration → host → mineralization
Notably, this hole showed an increase in molybdenum content at depth, with grades in the final 200 metres of core frequently returning assays above 100 g/t Mo.
Both drillholes EX_BRES_555_02A and EX_BRESPO_03 were stopped due to technical limitations and both terminated in mineralization, which remains open at depth (Figure 5).

Building on the results of the ongoing drilling program, drill hole EX_BRESPO_03A was designed to test the northeast extent of the Brevene Porphyry South target and is located between EX_BRESPO_03 and EX_BRES_01A. Assay results from this drillhole returned a wide interval grading 707 metres of 1.08 g/t AuEq (0.56 g/t Au, 0.48% Cu and 40.18 g/t Mo) from 1,175 metres downhole.
