Key Terms

copper equivalent, scandium oxide (Sc2O3), preliminary economic assessment (PEA), mineral resource estimate (MRE), +4 more

8 terms

copper equivalent technical

"Copper Equivalent (CuEq) values exclude scandium (Sc2O3)."

Copper equivalent is a single, standardized number that converts the value of all metals in a mineral deposit into the equivalent amount of copper, using current metal prices and processing recoveries. Think of it as putting different coins into one currency so you can compare the total worth at a glance; investors use it to assess and compare the economic attractiveness of mining projects and expected revenue per unit of ore.

scandium oxide (Sc2O3) medical

"technical viability of recovering high-purity scandium oxide (Sc2O3) from copper porphyry"

Scandium oxide (Sc2O3) is a white, powdery compound of the rare metal scandium used as an additive in ceramics, lighting, electronics and high-performance aluminum alloys. Think of it like a pinch of seasoning that can make materials much stronger, lighter or more efficient. Its scarcity and specialized uses can create price swings and supply risk, so changes in availability or demand can materially affect companies in mining, materials and advanced manufacturing.

preliminary economic assessment (PEA) financial

"will be incorporated in the current and future engineering studies *Copper Equivalent"

A preliminary economic assessment (PEA) is an early-stage study that shows whether a proposed mining or resource project could make money by estimating likely production levels, costs, and returns using accessible but limited data. It matters to investors because a PEA acts like a rough business plan or feasibility snapshot: it highlights potential value, capital needs and main risks so investors can decide whether to fund further, more detailed work or walk away.

mineral resource estimate (MRE) technical

"revised version of the 2024 Mineral Resource Estimate (MRE-2) and the Preliminary"

A mineral resource estimate (MRE) is a calculated report of how much mineral material likely exists in a deposit and its average quality, based on sampling and geological data. Investors use it like a rough inventory and quality check for a potential mine — it helps gauge the scale and value while highlighting uncertainty and the need for further studies before any production or revenue can be assumed.

porphyry-style technical

"horizontal and vertical porphyry-style Hat deposit mineralization enriched in copper"

A porphyry-style deposit is a large, often deep-seated concentration of metals — commonly copper with gold or molybdenum — formed by long-lived hot fluids that spread mineralization over broad volumes of rock. For investors, these deposits matter because they can contain very large, mineable resources with consistent geometry, making them attractive for lower-cost, bulk mining and offering potential for long mine life and scalable production, even if grades are moderate (think of a chocolate-chip cookie where valuable "chips" are spread through the dough).

fire assay technical

"Gold, platinum, and palladium are assayed by 30-50 g fire assay with ICP-OES finish."

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.

ICP-OES technical

"30-50 g fire assay with ICP-OES finish. Multi-element analyses (up to 48 elements)"

An ICP-OES is a laboratory technique that measures the amounts of metals and other elements in liquids and solids by turning a sample into a hot, glowing gas and reading the light it gives off — like using a prism to read elemental “fingerprints.” Investors care because those readings determine compliance with safety and environmental rules, verify mineral content in mining reports, and confirm ingredient purity in manufacturing, any of which can affect a company’s costs, legal risk and reported resources.

ISO 17025 technical

"AGAT Laboratories in Calgary, an independent ISO 17025 and ISO 9001 certified facility."

ISO 17025 is an international standard that sets the rules for testing and calibration labs to show they produce accurate, consistent results and operate impartially. For investors, a lab that meets ISO 17025 is like a product carrying a trusted quality stamp—its test data and measurements are more likely to be accepted by regulators, customers and partners, reducing the risk that faulty or disputed testing will harm a company’s value or delay product approvals.

Vancouver, British Columbia--(Newsfile Corp. - December 4, 2025) - Doubleview Gold Corp. (TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) ("Doubleview" or the "Company") 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).*

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 algorithm are average trailing three years commodity prices, and do not reflect recent dramatic increases in prices of mineral commodities. Scandium recovery has been announced in the news release dated 25^th 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 the 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 estimate 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 accuracy and reliability of results.
