Doubleview Extends High-Grade Domains at Hat: H099 Returns 438m of 0.40% CuEq Including 52m of

1.02% CuEq, Expanding Mineralization Envelope Around Conceptual Pit vertically and laterally.

Vancouver, British Columbia — (December 4, 2025) — Doubleview Gold Corp. (“Doubleview” or the

“Company”) (TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) is pleased to announce assay results from drill holes

H097, H098, and H099 from its 2025 drill program at the Hat Polymetallic Deposit in northwestern British

Columbia. Drill holes H097, H098 and H099 were collared from the same platform as drill holes H093 –H096 and

were drilled into previously untested potential extensions of the deposit and have successfully expanded the

mineralized footprint approximately 100m laterally and 200 meters vertically and strengthened confidence in

continuity in part of the Lisle Zone.

Highlights

• H099 returned 438.0 metres of 0.40% CuEq, including 52.0 metres of 1.02% CuEq, representing one

of the strongest continuous mineralized intervals drilled at the Hat deposit to date .

• H097 and H098 confirm mineralization in previously undrilled sections and extend data

approximately 200–300 metres down-dip and up to 100 metres laterally and fill important gaps in the

geological exploration model.

• Drill holes H097, H098 and H099 when integrated into the database potentially will extend the 2024

conceptual open-pit shell by ~200 metres down-dip and up to 100 metres laterally, and demonstrate

strong expansion potential that may be realized in the revised version of the 2024 Mineral Resource

Estimate (MRE-2) and the Preliminary Economic Assessment (PEA).

• Drill hole analyses reported in this News Release show continuity of copper-gold-cobalt-scandium

domains [scandium is an emerging critical metal and an important component of the Hat deposit ], across

broad intervals of the system.

• These drill holes support the Company’s objective to complete an up-dated Mineral Resource Estimate

(MRE-2) and a Preliminary Economic Assessment (PEA) and improve confidence in the exploration

model all of which will be incorporated in the current and future engineering studies * Copper Equivalent

(CuEq) values exclude scandium (Sc2O3).*

These long intercepts continue to demonstrate and explore the dimensions of the horizontal and vertical porphyry -

style Hat deposit mineralization enriched in copper, gold, cobalt, silver, and scandium.

Geological Interpretation

Step-Out Drilling Adds Increased Volumes

H097–H099 were planned to intersect previously undrilled areas between and beneath the trace of previously

released drill holes (H093–H096). Although collared from the same surface location, the drill holes highlighted in

this News Release extended the dimensions of the deposit 200–300 metres at depth and up to 100 metres

laterally, successfully fulfilling the objective of characterizing untested volumes of the deposit.

Expansion of Conceptual Pit Potential

The strong continuity and grade distribution observed in drill hole H099, together with similar results from H097

and H098, extend the interpreted geometry of the mineralized body and potentially allow major extensions of the

conceptual pit by approximately 200 metres vertically and ~100 metres laterally. Note: the current

exploration model and conceptual pit design are based on available information and may not be supported by

future drilling and engineering studies.

Continuity & Resource Confidence

The drill holes included in this News Release were planned to improve the interpretation of deposit geology and

strengthen the block model used for resource estimates. The results confirm both lateral and vertical continuity

of the system and will contribute to higher confidence resource categories as the model is updated.

High-Grade Domains and Depth Potential

Drill hole H099 is particularly important as it highlights a strongly mineralized area of copper, et al. metals,

including more than 50 metres exceeding 1.0% CuEq, and demonstrates that high-grade zones continue to

depth. The extent of such high-grade zones has not been determined.

Critical Metals: Scandium & Cobalt

While scandium (Sc2O3) is not included in CuEq calculations, scandium grades remain consistent with prior drill

campaigns and continue to frame the Hat Deposit as a potentially significant North American source of critical

metals.

CEO Comments

Farshad Shirvani, President and CEO, commented:

“These new step-out holes continue to validate and strengthen our geological model of the Hat Deposit. H099, in

particular, delivered exceptional continuity with long and high-grade sections, confirming that the Lisle Zone

remains robust at depth. The drilling extended mineralization into untested areas and demonstrated expansion

potential for the conceptual pit by approximately 200 metres down-dip and 100 metres laterally.

These results reaffirm our confidence in the Hat model, highlight the presence of high -grade domains, and

demonstrate meaningful depth potential. Importantly, the new holes help us improve resource confidence and will

be incorporated into the upcoming resource estimation work. We are very encouraged by the consistent scandium

and cobalt values across the system, strengthening Hat’s profile as a strategic critical -metals project in British

Columbia. Our team is already planning follow-up drilling into several newly opened areas.”

Other notes:

Details of the algorithm used to estimate %CuEq are presented in the notes above. The metal values used in our current algori thm are average trailing three years

commodity prices, and do not reflect recent dramatic increases in prices of mineral commoditie s. Scandium recovery has been announced in the news release

dated 25th of November 2025 with an overall pre-optimized 82%.

Core samples are delivered securely to a fully accredited commercial laboratory and processed by industry -standard methods and include insertion of standard

samples, duplicate core samples and blank samples to ensure confidence.  Assays are received from t he analytical laboratory at irregular intervals, verified by

reference to notes provided by our field crew, added to our database, and disseminated publicly by News Release.    

“The scandium resource potential is based on the drill holes on the property drilled for (July 25, 2024) maiden resource esti mate for other metal content than

scandium. The potential quantity and grade are conceptual in nature, there has been insufficient exploration to define a mineral resource, and it is uncertain if

further exploration will result in the target being delineated as a mineral resource.

Quality Assurance and Quality Control:

Hat Project drill cores are processed at Doubleview’s field camp where they are photographed, measured and

logged by our technical staff and then divided using a diamond bladed saw. One half is placed in a stout bag to

form the assay sample that is forwarded securely to the independent analytical lab. The remaining half core is

stored on site where it is available for further examination and sampling. The assay cores are subject to a Chain

of Custody routine as they are shipped from camp to a bonded carrier for delivery to the lab.

All core samples are prepared and analyzed at AGAT Laboratories in Calgary, an independent ISO 17025 and

ISO 9001 certified facility. Samples are dried, crushed to 70% passing 2 mm, split to obtain a 250 g representative

portion, and pulverized to 85% passing 75 µm. Gold, platinum, and palladium are assayed by 30–50 g fire assay

with ICP-OES finish. Multi-element analyses (up to 48 elements) are performed by four-acid digestion with ICP-

OES/MS, with ore-grade assays applied where required. Selected samples are further analyzed for whole-rock

oxides using lithium borate fusion with ICP-OES, and Loss on Ignition is determined separately. Routine quality

assurance protocols include insertion of blanks, duplicates, and certified reference materials, ensuring acc uracy

and reliability of results.
