Valkea Resources Strengthens the Bulk-Tonnage Gold Potential of the Koivu Zone at the Paana Project, Northern FinlandVancouver, British Columbia--(Newsfile Corp. - December 9, 2025) - Valkea Resources Corp. (TSXV: OZ) (OTCQB: OZBKF) (the "Company" or "Valkea") is pleased to announce drill results from the 2025 fall exploration drill program at its 100% owned Paana project in Lapland, Finland. The 2,454-meter, seven-hole drill program targeted bulk-tonnage gold mineralization at the Koivu Zone, Aarnivalkea West target (Figure 2). Highlights Fall 2025 Paana Project drill program complete: Seven drill holes at the Koivu Zone (Aarnivalkea West target) tested the up-dip and strike-extent of disseminated gold mineralization discovered in historical hole FAVD-64 (55.48 meters of 1.63 g/t gold including 8.50 meters of 8.57 g/t gold from 158.0 meters downhole7) and confirmed in hole AW-24-005 (36.45 meters of 1.50 g/t gold including 15.35 meters of 3.43 g/t gold from 150.15 meters down hole, see the Company's February 27th, 2025 news release).Assay results demonstrate continuity of bulk-tonnage style gold mineralization at the Koivu Zone covering a 200-meter dip extent and over 100-meter strike extent where it remains open down-dip and along strike:10.4 meters of 0.54 g/t gold at 193.95 meters downhole and 12.77 meters of 0.77 g/t gold including 6.0 meters of 1.15 g/t gold at 331.8 meters downhole in drill hole AW-25-0105.6 meters of 1.13 g/t gold at 92.45 meters downhole in drill hole AW-25-00715.2 meters of 0.35 g/t gold at 18.0 meters downhole in drill hole AW-25-008Vein-hosted gold mineralization intersected outside of bulk-tonnage mineralization:17.55 g/t gold over 0.5 meters at 282.85 meters downhole in AW-25-012Further drilling is warranted across the Aarnivalkea West target towards the southern Honka Zone, 500 meters south of Koivu, where previous drill programs discovered zones of high-grade mineralization (e.g., 18.14 g/t gold over 4.0 meters at 223.0 meters downhole in drill hole FAVD626).Results are pending from a Phase 1, 300-hole base of till (BoT) program conducted across parts of the Paana Project designed to strengthen the pipeline of high-priority drill targets. Phase 1 BoT program represents a small portion of the planned project-wide survey."Results from our follow-up Fall 2025 drill program at the Paana Project focused on the newly established Koivu Zone," stated Chris Donaldson, CEO & Executive Chair. "Drilling continues to validate the geological and structural interpretation for the target area, with mineralized domains now demonstrated to extend both up-dip and along strike. The majority of holes intersected broad zones of bulk-tonnage style gold mineralization, supporting continuity from previously reported strong results. Collectively, the results indicate that the gold system at Aarnivalkea West is substantial and complex, with potential for both broad, continuous mineralization and localized higher-grade zones. Follow-up step-outs down-dip and southward toward the high-grade Honka Zone are warranted to further assess the scale and characteristics of this emerging target." Aarnivalkea West TargetThe Aarnivalkea West target, located approximately 24 km northwest of Agnico Eagle's Kittilä mine and 65 km northwest of Rupert Resource's Ikkari deposit (Figure 1), is underlain by highly prospective rocks of the Central Lapland Greenstone belt. Based on previous exploration programs, the broad and open 1.3 km long target is considered prospective for both Kittila-style, high-grade mineralization and Ikkari-style disseminated mineralization.Drill ProgramBulk tonnage-style gold mineralization at the Koivu Zone, the northern extent of the Aarnivalkea West target (Figure 2), is modelled within a series of east-dipping domains (Domains A and B). Gold mineralization consists of quartz-carbonate-pyrite veins, veinlets and disseminated pyrite associated with broad zones of carbonate-sericite±albite alteration hosted in deformed and sheared intermediate volcanic rocks and diorite porphyries. Higher grade mineralization consists of locally intense albite alteration (bleaching) cut by quartz-carbonate-pyrite veins (e.g., 64.2 g/t Au over 0.5 meters in AW-25-005, see February 27th, 2025 news release). The fall 2025 drill program at Koivu consisted of 2,454 meters of core drilling in seven holes (Figure 2). The drill holes were collared along three sections with 270o azimuths and -55o dips. Drilling primarily tested the mineralization potential of Domain A - up-dip and along strike (north and south) of holes FAVD64 (55.48 meters of 1.63 g/t gold including 8.50 meters of 8.57 g/t gold from 158.0 meters downhole7, Figure 3) and AW-25-005 (36.45 meters of 1.50 g/t gold including 15.40 meters of 3.43 g/t gold from 150.2 meters downhole7, see February 27th, 2025 news release). Two holes (AW-25-007 and AW-25-008) were drilled up-dip from AW-24-005 along section 7552400N (Figure 3), two holes (AW-25-009 and AW-25-0
