Doubleview Gold Corp Announces Important High-Grade Copper and Gold Intercepts at Hat Polymetallic Deposit in Northwestern British Columbia

Highlights:

• 2025 season drilling totals 8,506 metres in 12 drill holes and is continuing.

• Drill hole assay intervals include some of the highest-grade mineralization intercepted to date at the Hat Project.

• Recent drill holes are extending the mineralization envelope of the Hat deposit and will be incorporated in the next Mineral Resource Estimate.

Vancouver, British Columbia–(ACN Newswire via SeaPRwire.com – September 11, 2025) – Doubleview Gold Corp. (TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) (the “Company” or “Doubleview”) is pleased to announce important and very significant assay results from its 2025 drilling program at the Hat Polymetallic Deposit in northwestern British Columbia. The results from drill holes H090, H091, and H092 include some of the most substantial intervals of high-grade copper and gold mineralization encountered at the Hat Project to date and expand the footprint of mineralization well beyond the area considered in the maiden Mineral Resource Estimate that was reported in a 25/07/2024 news release. Drill holes H090, H091, and H092 provide more details of the East Lisle Zone, and shallow extension of the Main Lisle Zone.

Partial Data from 2025 Drill Holes:

The recent drilling focused on the core Lisle Zone, where drilling intercepted what is interpreted as a potential porphyry feeder zone. The intercepts demonstrate both shallow and deep mineralization horizons and provide further evidence of the Hat Deposit’s robust mineralization profile.

Table 1 summarizes important assay intervals from drill holes H090, H091 and H092. [Note that scandium (Sc) values are excluded from copper equivalent estimates but are shown to ensure complete disclosure of relevant data]. Data from subsequent drill holes will be released when assays are received and have been verified. To date (11/09/2025) 12 drill holes have been completed with total 8,506 metres (27,906 feet) and work is continuing.

Au recovery: 89.0%; Ag recovery: 68.0%; Cu recovery: 84.0%; Co recovery: 78.0%. * Copper Equivalent Calculation CuEq in % = ([Ag grade in ppm] *24*0.68/31.1035 + [Au grade in ppm] *1900*.89/31.1035 + 0.0001* [Co grade in ppm] *22*0.78*22.0462 + 0.0001* [Cu grade in ppm] *4*0.84*22.0462)/(4*22.0462*0.84).

Table 2 summarizes coordinates of the recent drill holes.

DDH ID	UTM- East (m)	UTM- North (m)	Elevation (m)	Azimuth  (°)	Dip (°)	Max- Depth (m)	Year
H090	347703	6454749	1025	-65.12	90	501	2025

H092	347963	6453927	966	-61.83	120	741	2025

 

Drill hole H090 shows a very long interval 241.8 metres (793.3 feet) of mineralization with 0.15% CuEq within which are 68 m of 0.30% Cu Eq that includes 16.6 m of 0.76% CuEq.

Drill hole H091 shows several intervals with elevated levels of %CuEq, of which 153m to 180 metres (27m/88.6 ft) carries 0.58% CuEq and a remarkable 5.26% CuEq over 1.2m [Please note that the latter is an obvious outlier with 0.37% Cu, 6.43 g/t Au, 7.16g/t Ag and 230 g/t Co].

Drill hole H092 also shows numerous long intervals of high %CuEq including some near surface and others at depth that illustrate the potential for locating one or more “feeder” zones to the main Lisle Zone.

The grades and intercepts reported from holes H090, H091 and H092 confirm the high-grade nature of the mineralization within parts of the Lisle Zone and may be indicative of proximity to the “core” and possible “feeder” zone. The intercepts display consistent copper, gold and strong cobalt values, as well as consistent scandium mineralization, further reinforcing the Hat Deposit’s potential as a significant resource of strategic metals.

Figures 1 and 2 illustrate in plan and sectional views the recent drill holes H090 and H091 along with a conceptual open pit outline. The conceptual pit likely will be adjusted substantially as more data becomes available.

Figure 3 illustrates drill hole H092 and pre-existing drill holes. H092 is one of the most important drill holes on the Hat property because it greatly extends the zone of higher-grade mineralization easterly and to depth. Several subsequent drill holes were designed to confirm and explore this area.

President and CEO, Farshad Shirvani, commented:

“We are very pleased to present initial assay data from our 2025 field season. Included in the data are several startlingly important features of high-grade mineralization and expanded dimensions. We look forward to their inclusion in an MRE and Preliminary Economic Assessment (PEA) in progress. Meanwhile we await with considerable interest the receipt additional assay data.

We are also watching with great interest the steadily rising prices for our principal metals, copper, gold, silver and scandium, as the world markets react to this period of uncertainty, a new era of fractured trade relationships, global warming, inflation, and tariffs and the renewed emphasis on strategic metals. The recently announced possible merger of Teck Corporation with Anglo-American illustrates the active consolidation within the mining industry as established members seek to increase and buffer their positions.

We believe that Doubleview will play an important role in Canada’s mining industry as we expand our resource and plan for a bright future.”

Quality Assurance and Quality Control:

Hat Project drill cores are processed at Doubleview’s 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.

Core samples are analysed at the North Vancouver facility of ALS Canada Ltd. using their PREP-31, PGM-ICP24, ME-MS61, and ME-ICP06 packages. Each core sample is dried, then crushed to 70% passing a 2mm screen. All material is processed in an automatic Riffle splitter to yield a 250g homogenized, representative sample. This sub-sample is then pulverized to 85% passing a 75-micron screen. All samples are analyzed for Au, Pt, Pd by 50g fire-assay fusion/ICP-ES finish, using PGM-ICP24 package. A separate 0.25g pulp split is analyzed by Four Acid digestion/ICP-MS finish, reporting 48 elements. Over limit elements are analyzed by Ore Grade Four Acid digestion/ICP-ES finish using ME-OG62 assay package. All of Doubleview’s core samples are analyzed or assayed at independent ISO 17025 and ISO 9001- certified laboratories.

When initial assays are received and accepted by our staff, a certain fraction of the samples will be sent to a second ISO-certified lab for check assay and verification purposes. Assays will be reported in News Releases.
