Analysis

The stock moved +5.7% in the session following this news. A strong positive reaction aligns with repeated confirmations that Koivu hosts continuous bulk-tonnage gold with embedded high-grade veins. The company has steadily advanced Paana through 2025 with drilling and BoT work, and past exploration news sometimes saw supportive price moves after assays. However, the stock trades well below its 52-week high of 0.59, and prior rallies have not always been sustained, so funding needs and exploration risk could still cap follow-through.

bulk-tonnage technical

"targeted bulk-tonnage gold mineralization at the Koivu Zone"

Bulk-tonnage describes a large, continuous body of mineral-bearing rock that can be mined in high volumes using large-scale methods like open-pit or bulk underground mining. For investors, it signals potential for steady, lower-cost production because extracting more material at moderate concentration often spreads fixed costs over greater output, similar to buying in bulk to lower the price per unit.

pyrrhotite medical

"quartz-pyrrhotite veins and vein stockworks and quartz-carbonate-pyrrhotite-pyrite-chalcopyrite"

Pyrrhotite is a naturally occurring iron‑sulfur mineral often found in rock and ore deposits. It can slowly change when exposed to air and water, producing expansion and corrosive byproducts that damage concrete, foundations and buried infrastructure. For investors, pyrrhotite is important because its presence can reduce the value of real estate, raise construction or remediation costs, and affect mining project economics — like finding hidden termites in a building that can trigger large, unexpected repairs.

chalcopyrite medical

"quartz-carbonate-pyrrhotite-pyrite-chalcopyrite cemented breccias"

Chalcopyrite is a common copper-bearing mineral (a copper-iron sulfide) that often looks brassy yellow and is the main source of mined copper worldwide. For investors, its presence and abundance in a rock deposit determine how much recoverable copper a mine can produce and how profitable extraction will be — think of chalcopyrite as the concentrated ingredient that makes an ore body valuable and worth developing.

ICP-MS technical

"analyzed for 48 elements by ICP-MS on a 0.25-gram aliquot"

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is a scientific technique used to detect and measure very small amounts of metals and other elements in a sample. It works like a highly sensitive scanner, helping researchers identify the presence of specific materials with great accuracy. For investors, understanding ICP-MS is important because it highlights advanced methods used in industries such as mining, environmental testing, and manufacturing, influencing the valuation and risks of related companies.

fire assay technical

"Gold was analyzed by fire assay on a 30-gram aliquot"

Fire assay is a laboratory process used to accurately measure the amount of precious metals, like gold or silver, in a sample of ore or material. It involves heating the sample intensely to separate the metals from other substances, much like melting and purifying metal to determine its purity. This method is important to investors because it provides precise data on the metal content, helping to assess the value of mining operations or mineral deposits.

gravimetric finish technical

"reanalyzed by fire assay using a gravimetric finish on a 30-gram aliquot"

A gravimetric finish is a precise way of measuring the final weight of a product or material after processing or manufacturing. It ensures that the final amount meets exact standards, similar to weighing ingredients carefully in cooking. For investors, it indicates attention to quality control and consistency, which can impact a company's reputation and product reliability.

QA/QC technical

"monitored through the Company's quality assurance and quality control program (QA/QC)"

QA/QC stands for Quality Assurance and Quality Control, processes used to ensure products or services meet certain standards. Think of it as a way to check that a product is safe and works properly before reaching consumers, similar to how a chef tastes food before serving it. For investors, strong QA/QC practices indicate a company's commitment to delivering reliable, high-quality offerings, reducing risks and building trust.

Vancouver, 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 27^th, 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-25-010

  • 5.6 meters of 1.13 g/t gold at 92.45 meters downhole in drill hole AW-25-007

  • 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:

  • 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 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 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 27^th, 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 270^o azimuths and -55^o 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.

Sampling, Chain of Custody, Quality Assurance and Quality Control

All drill core analytical results have been monitored through the Company's quality assurance and quality control program (QA/QC). Drill core was sawn in half at Valkea's dedicated and secure core logging and processing facility in Sodankylä, Finland.

Half of the drill core was sampled and delivered in secured bags to the ALS Global preparation facilities in Sodankylä, Finland. Core samples were prepared using ALS standard preparation procedure PREP-31A which involves crushing the sample to 70% less than 2mm, followed by a riffle split of 250g, and then a pulverised split to better than 85% passing 75 microns.

Following sample preparation, the pulps were sent to the ALS Global analytical laboratory in Galway, Ireland for analysis. ALS Global is registered to ISO/IEC 17025:2017 accreditations for laboratory procedures.

Drill core samples were analyzed for 48 elements by ICP-MS on a 0.25-gram aliquot using a four-acid digestion (method ME-MS61). Gold was analyzed by fire assay on a 30-gram aliquot with an AES finish (inductively coupled plasma atomic emission spectroscopy - method Au-ICP21). Overlimit samples (>10 ppm Au) were reanalysed by fire assay using a gravimetric finish on a 30-gram aliquot (Au-GRA21).

In addition to ALS Global laboratory QA/QC protocols, Valkea implements a rigorous internal QA/QC program that includes the insertion of field and lab duplicates, certified reference materials (standards prepared by an independent lab) and blanks into the sample stream. Data verification of the analytical results includes a statistical analysis of the QA/QC data. Results are considered acceptable.

This news release contains forward-looking statements or forward-looking information relating to the future operations of the Company and other statements that are not historical facts. Forward-looking statements in this news release include but are not limited to statements regarding the Company's exploration plans.

Forward-looking statements are based on the reasonable assumptions, estimates, analyses and opinions of management made in light of its experience and its perception of trends, current conditions and expected developments, as well as other factors that management believes to be relevant and reasonable in the circumstances at the date that such statements are made, but which may prove to be incorrect. Management believes that the assumptions and expectations reflected in such forward-looking statements are reasonable. Assumptions have been made regarding, among other things: the Company's ability to carry on exploration and development activities; the timely receipt of required approvals; the price of metals; and the Company's ability to obtain financing as and when required and on reasonable terms. Readers are cautioned that the foregoing list is not exhaustive of all factors and assumptions which may have been used.

Forward-looking statements are subject to known and unknown risks, uncertainties and other factors that may cause actual results to be materially different from those expressed or implied by such forward-looking statements. Such risks, uncertainties and other factors include but are not limited to: the Company's early stage of development; the fluctuation of the price of metals; the availability of additional funding as and when required; the speculative nature of mineral exploration and development; the timing and ability to maintain and, where necessary, obtain necessary permits and licenses; the uncertainty in geologic, hydrological, metallurgical and geotechnical studies and opinions; infrastructure risks, including access to water and power; environmental risks and hazards; risks associated with negative operating cash flow; and risks associated with dilution. For a further discussion of risks relevant to the Company, see the Company's other public disclosure documents.

Although management has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended.

FAQ

What were the best drill intercepts at Paana reported December 9, 2025 (OZBKF)?

Highlights include 12.65 m @ 0.77 g/t Au (including 6.00 m @ 1.15 g/t) in AW-25-010, 5.60 m @ 1.13 g/t Au in AW-25-007 and a vein sample of 17.55 g/t Au over 0.5 m in AW-25-012.

How much of the Koivu Zone footprint did Valkea expand in the Fall 2025 drill program (OZBKF)?

Drilling extended Koivu-style bulk-tonnage mineralization to about a 200 m dip extent and over 100 m strike, with both directions remaining open.

Does Valkea plan follow-up drilling at Paana after the December 9, 2025 results (OZBKF)?

Yes. The company said additional step-out drilling down-dip and south toward the Honka Zone is warranted, plus testing the new pyrrhotite-associated zone in AW-25-010.

What is the significance of the 17.55 g/t Au result in AW-25-012 for OZBKF investors?

The 17.55 g/t Au over 0.5 m demonstrates localized high-grade vein potential within the Koivu area, complementing broader bulk-tonnage intercepts.

Are there remaining gaps or risks at the Paana Project highlighted in the December 9, 2025 release (OZBKF)?

Yes. A ~500 m gap between Koivu and Honka is sparsely tested and one drill hole (AW-25-011) returned no significant intervals; further drilling is needed.

When will the Phase 1 base-of-till (BoT) results be available for Paana (OZBKF)?

The release states Phase 1 BoT results are pending and will be used to refine additional sampling and drill targets; no specific date was given.
