Valkea Resources Strengthens the Bulk-Tonnage Gold Potential of the Koivu
Zone at the Paana Project, Northern Finland
Vancouver, British Columbia – December 9, 2025 – Valkea Resources Corp. (the “Company” or “Valkea”)
(TSX.V: OZ ) (OTCQB: OZBKF ) 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 downhole 7) and confirmed in h ole 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:
o 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-25-010
o 5.6 meters of 1.13 g/t gold at 92.45 meters downhole in drill hole AW-25-007
o 15.2 meters of 0.35 g/t gold at 18.0 meters downhole in drill hole AW-25-008
• Vein-hosted gold mineralization intersected outside of bulk-tonnage mineralization:
o 17.55 g/t gold over 0.5 meters at 282.85 meters downhole in AW-25-012
• Further 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 a t 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 Target
The 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 Program
Bulk 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 s even 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 27 th, 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-25-010) were drilled along section 7552350N (Figure 4), and three holes (AW-25-011, AW-25-
012 and AW-25-013) were drilled along section 7552450N (Figure 5).
Drill results confirm the geological and structural model for the target area and extend mineralized
domains up-dip and along strike (e.g., Domain A, Figures 3, 4 and 5). Results show continuity of bulk -
tonnage style gold mineralization over a 200-meter dip extent and over 100-meter strike extent where it
remains open down-dip and along strike. New insights from the drilling include:

• Drill holes AW -25-009 and AW -25-010 extend the strike- extent of Domain A , 50 meters south.
Both holes intersected broad zones (up to 100 meters) of disseminated pyrite with intervals of
strong carbonate-sericite-albite alteration with local bulk-tonnage style gold mineralization (e.g.,
10.4 meters of 0.54 g/t gold from 193.95 meters downhole in AW-25-010 and 10.3 meters of 0.56
g/t gold from 138.8 meters downhole in AW-25-009, Table 1). A new zone of mineralization was
also intersected near the bottom of AW -25-010 consisting of quartz-pyrrhotite veins and vein
stockworks and quartz-carbonate-pyrrhotite-pyrite-chalcopyrite cemented breccias . This new
zone of gold mineralization returned 6.0 meters of 1.15 g/t gold within 12. 65 meters of 0.77 g/t
gold from 331.8 meters downhole (Table 1 and Figure 4). Further drilling is warranted to test the
extent of this zone of mineralization.
• All three holes drilled to the north intersected broad zones of Koivu-style alteration with local bulk-
tonnage gold mineralization (e.g., 15.2 meters of 0.34 g/t gold at 190.75 meters downhole in AW-
25-012, Figure 5) within Domain A. Higher-grade mineralized veins, outside of Domain A , were
also intersected in AW-25-012 (17.55 g/t gold over 0.5 meters at 282.85 meters downhole, Table
1 and Figure 5) which demonstrates the added high-grade vein potential of the target area.
Summary and Next Steps
The fall 2025 drill program at the Paana Project accomplished its two main objectives: 1) expand the
footprint of bulk-tonnage style mineralization at the Koivu Zone, and 2) refine the geological and structural
model for the target area.
Gold mineralization along Domain A is now modelled over a 200-meter dip extent and at least 100-meter
strike extent where it remains open. Further drilling is warranted to test the extent of Domain A while
focusing on targeting higher-grade zones that are known to exist within the bulk-tonnage mineralization
(e.g., FAVD64 and AW-24-005, Figure 3). Additional drilling aimed at testing the extent of the pyrrhotite-
associated gold zone near the bottom of AW-25-010 is also warranted (Figure 4).
The 500-meter gap between the southern Honka and the northern Koivu zones also warrants systematic
drill testing. This area has only been investigated at depth with one drill hole (FAVD66, Figure 6), which
intersected zones of strong bulk-tonnage gold mineralization (e.g., 18.6 meters of 1.09 g/t gold from 220.0
meters downhole9, Figure 6) and confirms the strong prospectivity of sparsely tested area.
Results are pending from a Phase 1, 300-hole base of till (BoT) survey conducted across parts of the Paana
Project. Phase 1 sampling is part of a larger, planned project -wide BoT survey. The focus of the Phase 1
BoT program was on evaluating the footprints of high-priority gold anomalies defined in earlier programs.
Results from the Phase 1 BoT program will be used to refine areas for additional BoT sampling as well as
to refine new drill targets across the Paana Project.
