Cosigo Resources Acquires Bulk Sample for Prospecting Analysis

VICTORIA, CANADA — December 31, 2025 — Leads & Copy —

Cosigo Resources Ltd. (TSXV: CSG) recently acquired a 120-kilo bulk sample from outcroppings of “Chicken Coop” conglomerate material for prospecting analysis, according to a press release. The source area is located south of Cosigo’s field camp within the Taraira title.

Company employees, supervised by geological consultants and management, hand-chipped and securely packaged the samples before forwarding them to analytical facilities in Vancouver, Canada.

Cosigo’s geological team previously located outcroppings of conglomerate stratum type material, distinct from material mined by artisanal miners, as reported in a news release dated Aug. 10, 2023. That release included analytical results for 14 channel samples from the 1019 metre strike length of outcroppings, with plans announced for further testing.

The samples were subsequently tested by the non-destructive Chrysos assay system by MSA Lab, an accredited laboratory in BC, Canada.

Analyses for the channel samples are reproduced here for reference purposes:

Drilling in 2024 intercepted what it believes is the same “Chicken Coop” conglomerate layer. Analyses, identified below in grey with greater than 0.50 ppm gold highlighted in yellow, were obtained from core samples.

The company has not satisfactorily identified the conglomerate as “Chicken Coop” and further work is required. Similar outcroppings have been found along as much as 27 kms of the host ridge and further prospecting and mapping may lead to identification of related quartzite layers that are highly prospective. These may not be Chicken Coop rocks but alternatively may be a wholly different horizon that had not been recognized previously.

The 120 kg sample of apparent “Chicken Coop” conglomerate will be treated by gravity concentration methods, with the exact method selected in consultation with the lab’s personnel. Separately, a four- or five-drill hole campaign to obtain strata samples will be directed to the Taraira Ridge using the company’s portable drill. Samples will allow better identification, characterization and analysis and remove uncertainties. Further drilling may follow.

A private placement of up to CAD$1,000,000, previously announced and initiated on Dec. 10, 2025, comprises Units priced at CAD$0.08 with a full warrant priced at CAD$0.15. Each warrant entitles the holder to purchase an additional common share at a price of CAD$0.15 for 60 months from the closing date of the private placement.

The private placement is being offered on a non-brokered basis, and all securities will be subject to a statutory hold period of four months and a day from the offering's closing date, pursuant to securities laws in Canada and, where applicable, the TSX Venture Exchange hold period. The company may pay a finder’s fee on a portion of the gross proceeds of the private placement, subject to the TSX Venture Exchange's approval.

The company intends to use the net proceeds of the offering to conduct the next level of prospecting, mapping, and sampling on the company’s Taraira property, the Willow Creek, Nevada, property, and for general working capital.

Erik Ostensoe, P.Geo., a geological consultant to the company and a Qualified Person as defined by National Instrument 43-101, has reviewed and approves the scientific and technical disclosure in this news release.
