• This news release presents results from recent drilling in the southeast section of the Hat Project's Lisle Zone. Drill holes H093, H094, H095, and H096 have significantly expanded the apparent volume of the mineralized zone, extending beyond the conceptual pit wall outlined in the 2024 Preliminary Mineral Resource Estimate. These results will be incorporated into the Preliminary Economic Assessment, which is nearing completion.

• A few of the outstanding intercepts:
  • DH H093: 640.7m (2102.1 feet) from depth 16.3m to 657.0m with 0.34% CuEq including 133m with 1.03% CuEq (0.65% Cu and 0.4g/t Au)

  • DH H094: 510.0m (1673.3 feet) from 30m to 540.0m with 0.22% CuEq (0.11% Cu and 0.10g/t Au)

  • DH H095: 110m from 430.0 to 540.0 with 0.91% CuEq (0.50% Cu and 0.12g/t Au)

  • DH H096: 681.4m (2235.7 feet) from depth 38.6 m to 720.0m with 0.37% CuEq, including 71.0m with 1.01% CuEq (0.54% Cu and 0.51g/t Au)

  • The apparent footprint is increased by approximately 400m X 330m.

• Additional assay data are forthcoming. Drilling is continuing.

Vancouver, British Columbia--(Newsfile Corp. - October 1, 2025) - Doubleview Gold Corp. (TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) is pleased to announce assay results from recent drill holes H093, H094, H095 and H096 from its Hat Project strategic and critical metals property in NW British Columbia. Assay highlights from drill holes H090, H091 and H092 were included in a recent news release, dated September 11, 2025, that presented highly significant intercepts.

Summarized composite assays from drill holes H093, H094, H095 and H096 are presented. Scandium values are not included in estimates presented in this and earlier news releases. Doubleview believes that scandium, a critical metal with many applications in electronic and as any alloy, has the potential to add significant value to the Hat deposit.

Table 1: Summary of Significant % CuEq Drill Core Intercepts

Notes:

1 - Copper Equivalent (CuEq) currently does not include Scandium

2 - The intervals presented in this table are not true widths. The true width of mineralized sections has not been determined.

3 - Metal equivalents should not be relied upon for future evaluations. Drill hole intercepts included in this news release are core lengths that may or may not represent true widths of mineralization. It is not possible to determine true widths.

4 - Parameters used to calculate Copper Equivalent: Au price (US$/oz): 2365.09; Ag price (US$/oz): 27.43; Cu price (US$/lb): 4.17; Co price (US$/lb): 14.76. 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] *27.43*0.68/31.1035 + [Au grade in ppm] *2365.09*.89/31.1035 + 0.0001* [Co grade in ppm] *14.76*0.78*22.0462 + 0.0001* [Cu grade in ppm] *4.17*0.84*22.0462)/(4.17*22.0462*0.84).

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, a potentially recoverable high value strategic alloy metal (customarily quoted as Sc2O3 ) that is present in small but possibly highly important amounts in Hat mineralization, is not assigned any value pending metallurgical investigations and recoverable results.

Core samples are delivered securely to a fully accredited commercial laboratory and processed by industry-standard methods. Assays are received at irregular intervals, verified by reference to notes provided by our field crew, added to our database, and disseminated publicly by News Release.

Drill holes H093, H094, H095 and H096, as shown in Figure 1, are located in proximity to hole H092 and further explore the area of high metal values (i.e. H092: 411.5m with 0.62% CuEq) in an easterly extension of the main Lisle Zone. The combination of drill hole data from H090 to H096 added an approximate domain of 330 m x 400 m to the Lisle deposit that has not been delimited in any direction. Numerous intervals from those holes are included in Table 1 of this News Release.

A composite of Hole H093 assays from16.3m to 693m comprises 676.7m (2220 feet) with 0.33% CuEq. Within that long mineralized section there are several higher-grade intervals, including 63.0m (206.7 ft) with 1.88 %CuEq and 21.0m (68.9 ft) with 4.78 %CuEq and 9.0m (29.5 ft) with 9.88% CuEq.

A composite of drill hole H094 assays included 107.6m (353 ft) with 0.30% CuEq, in an almost throughout mineralized hole from 30 m (98 ft) to 540 m (1772 ft ) with 0.22% CuEq.

Drill hole H095 is believed to have followed in an unmineralized fault that does not represent the limit of mineralization; the drill hole did not leave the fault.

Mr. Farshad Shirvani, President and CEO, comments that: We believe that the previously disclosed assays, combined with assays presented in this News Release and, speculatively, additional data from core samples that are being processed in the laboratory, will further reinforce our conceptual mineral deposit model, promote resources from Indicated and Inferred categories to higher confidence levels, including Measured, and require re-design of the current open pit layout. The new drill holes will be added in a revised MRE (Maiden Resource Estimate 2025) and the PEA (Preliminary Economic Assessment) that is on-going. Drill holes H093, H094 and H095 have contributed greatly to achieving new dimensions in the eastern part of the Hat deposit. This exciting new area necessitates a vigorous follow up that is currently on our agenda. Both the "footprint" and value of our project have been greatly increased, not only by the expansion but also by the recent dramatic increase in metal, mineral and commodity prices."

Initial scoping of the implications of this new assay information allowed our field crew to revise and re-direct our efforts to concentrate on better defining the deposit. We hope to release further drill hole assay data soon."

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.
