Historical archives and compilation validate and confirm the mineralization at the Blue Lake Cu (Ni-PGE) project

TORONTO, Nov. 4, 2026 /CNW/ -- Cupani Metals Corporation ("Cupani" or the "Company") (CSE: CUPA) (OTCQB: CUPIF) announces the acquisition of a large historical exploration archive in Q2 2026. Verification, compilation, and tabulation of the data created a database encompassing about 98% of all 587 holes drilled on the Blue Lake Project. With such a high-quality database now in hand, Cupani plans an independent 43-101 mineral resource estimate for delivery in 2027.

• 57,000 meters in 575 historic DDH from La Fosse and Hollinger have been drilled on and around the Blue Lake mineralized zones.
• Archive acquired: 42 boxes and dozens of map rolls, detailing exploration work from the 1950's, 1960's and particularly from the 1980's.
• Critical information from the infill and definition drilling at the Blue Lake mineralized zones was present in the archive; this data had never been submitted for assessment and was not available prior to Cupani acquiring the archive. Cupani now holds data in paper logs, assay certificates, maps, sections and plan schematics for the historic infill, adit and exploration drilling at Blue Lake.
• Independent validation of historical data: Sixteen twin holes drilled in 2012 by Rockland (executed by IOS Geosciences) intersected the historic mineralization in all lenses. These holes validated the original assays and lithologies.
• Next step: 43-101 mineral resources estimate by an independent Qualified Person during 2027 combined with additional drilling in order to further test the model.
• CEO comment: "Investors should review the Table 1 list of prior mineralized intersections obtained from historic drilling at Blue Lake. An independent 43-101 resource calculation gives Cupani credibility with communities, governments, investors and partners." said Brian Bosse, CEO of Cupani.

The archive

The archive contains exploration work by Hollinger and La Fosse across the Labrador Trough, held in 42 boxes. In the immediate surrounding of the mineralised zones at Blue Lake, it includes the physical records of 429 infill and exploration drill holes completed by La Fosse between 1987 and 1989 plus 119 drilled by Hollinger in 1955,1956,1967 and 1968. The recently acquired archive provides Cupani with a solid database covering about 98% of all historical drilling and exploration work.

Rockland (IOS Geosciences) drilled several holes in 2011, 2012 and 2015. The 16 holes drilled in 2012 were intended to validate the existing mineralised lenses. These were twins of historic holes that had returned significant mineralisation. The assays and lithologies of the twinned holes matched the reported data of the original holes, an important validation of the historical record.

The 2012 drill core remains stored in Chicoutimi, Quebec. It is available to Cupani and to an independent NI 43-101 author for examination in preparation for filing a technical report. Drill core from 2011 and 2015 is stored at the project site as well as all the core from drill holes by Hollinger and La Fosse. The core boxes are crosspiled and most of the core is still viable.

The archive also holds La Fosse compilations and reports on other mineralised zones within the Labrador Trough. These reports were never submitted to the Quebec Ministry of Mines and Resources and remain proprietary to Cupani. LINKED HERE is recent public reporting on the Blue Lake project. Cupani is reporting an 80% recovery assumption to be conservative until independent metallurgy work is available. Recovery was not considered in past reporting of mineralization.

Mineral resource estimate

Cupani intends to commission an initial 43-101 compliant mineral resource estimate for Blue Lake from an independent Qualified Person, with delivery anticipated in 2027. The Company views the estimate as important external validation of the project's potential.

Analytical procedures and QAQC

The analytical methods used by Hollinger are unknown, they are not presented in their reports and logs. The historical samples from La Fosse were sent to Lakefield Research and Assayers (Ontario limited) but analytical methodology was not found in any report or certificate

The Hollinger holes were not assayed for Palladium and Platinum. In certain holes drilled by LaFosse, Nickel and Copper were not assayed, only Platinum and Palladium were assayed. In several holes magmatic massive sulphides were not analysed. The net effect of those decisions by prior operators may be to slightly underreport mineralisation until future assays are conducted.

Rockland sent their samples to ALS mineral laboratories in Val D'Or, Quebec in 2011, and in 2012 they were sent to Actabs. Precious metals, including Gold, Platinum and Palladium were assayed by the mean of fire-assay on two assay-tons (50 gr) with lead collection and ICP-MS finishing. Base metals, including Nickel and Copper, plus 49 other elements were analyzed by ICPMS and ICP-AES after partial Aqua Regia digestion.

He is acting as the Company's qualified person within the meaning of National Instrument 43-101 – Standards of Disclosure for Mineral Projects.
