COPPERNICO METALS EXPANDS CONCESSIONS AT SOMBRERO

Through Coppernico Metals Inc.'s wholly owned private Peruvian subsidiary, Sombrero Minerales SAC, the company has expanded its concessions through an application covering 2,400 hectares over a newly identified lithocap-epithermal-porphyry target at its Sombrero project in Peru.

The concessions were pursued after receiving encouraging early stage geological and geochemical sampling results from what the company is referring to as the Rumi target, located east-southeast of the Tipicancha target within the general Sombrero project area. Mapping and reconnaissance rock sampling have outlined a continuous footprint of approximately 2.3 kilometres (km) by 2.5 km of advanced argillic alteration developed within a Miocene or younger volcanic package, indicative of a potential high-sulphidation epithermal or lithocap-style system.

Highlights

• Large-scale lithocap: Approximately four square km of continuous kaolinite, alunite and silica alteration with a few occurrences of dickite and disseminated pyrite, mapped by field observations and short-wave infrared (SWIR) spectroscopy verification.
• Pathfinder anomalism: Initial reconnaissance sampling shows elevated arsenic (As), bismuth (Bi) and antimony (Sb), with sporadic elevated values of molybdenum (Mo) up to 10 parts per million (ppm) and copper (Cu) up to 101 ppm. High sulphur (S) values, greater than 3 per cent, are consistent with mapped pyrite-rich zones and acid sulphate alteration is consistent with high-sulphidation systems.
• Multiple systems: Displays features similar to the Tipicancha and Ccello targets, suggesting a regionally significant younger magmatic-hydrothermal event superimposed over the Ccascabamba-Nioc skarn targets.

Ivan Bebek, chair and chief executive officer of Coppernico, commented: "As our exploration efforts are ongoing at various targets at our Sombrero project, we continue to review opportunities in the region aiming to expand our pipeline of prospective discovery targets. The Rumi target is our 17th stand-alone target in our 56,400-hectare land position supporting our goal of pursuing multiple significant discoveries on the western side of the Andahuaylas-Yauri belt. Additional permitting updates and channel sampling results are expected in the coming weeks."

Reconnaissance mapping and initial sampling have outlined a large zone of advanced argillic alteration at the Rumi target, measuring approximately 2.3 km by 2.5 km. The alteration is characterized by kaolinite, alunite and vuggy to residual silica, with dickite occurring locally. Disseminated pyrite and native sulphur are common throughout the area.

This distinctive mineral assemblage and texture point to an acid-sulphate environment, typical of high-sulphidation epithermal systems and lithocaps that often develop above porphyry copper-gold (Cu-Au) centres. Early geochemical results from 16 samples collected, included elevated As, Bi and Sb, further supporting this interpretation. Samples also included sporadic elevated values of Mo up to 10 ppm and Cu up to 101 ppm.

Early structural mapping shows that the alteration coincides with intersections between northeast- and east-west-trending corridors. These structures and their intersections may have played an important role in focusing and channelling magmatic fluids. On the strength of these findings, Coppernico has staked approximately 2,400 hectares of new concessions. A follow-up mapping and sampling program is planned to better define the scale and context of this emerging system.

This new discovery expands Coppernico's growing pipeline of younger lithocap exploration targets within Peru's Miocene metallogenic belt, which now incorporates the Rumi, Tipicancha, Macha Machay and Ccello targets:

• Tipicancha: One km by two km epithermal alteration with Cu-bearing zones returning up to 22 m of 0.65 per cent Cu, including 10 m of 1.14 per cent Cu (true widths unknown, see Coppernico press release dated May 21, 2025).
• Macha Machay: Newly mapped four km by one km alteration zone supported by broad geochemical anomalies (additional exploration results pending, see company press release dated Aug. 18, 2025).
• Ccello: Approximately two km by 1.5 km silver-kaolinite lithocap with silver mineralization associated with quartz-alunite alteration and massive silica structures (see press release dated Sept. 30, 2019, by Auryn Resources, Coppernico's predecessor).

These Miocene-aged targets are superimposed over the westward extension of the older Eocene-Oligocene Andahuaylas-Yauri belt, an established porphyry Cu-Au province hosting the company's large-scale skarn-porphyry Ccascabamba and Nioc target areas and the Good Lucky target. These overlapping mineralizing events are likely indicating long-lived and multiphase magmatic and hydrothermal activity, suggesting the presence of deep-seated, crustal-scale structures and potential for concealed porphyry centres at depth. Regionally, the Miocene belt of Peru hosts numerous productive epithermal-porphyry systems. Notable examples include Morococha-Toromocho, located approximately 375 km to the north of Sombrero, and Inmaculada-Pallancata-Selene, nearly 150 km to the south.

In connection with the application of these concessions, the company paid the first year of annual concession validity fees equal to $3 (U.S.) per hectare. Final granting of the concessions is expected to be completed within the coming months, subject to customary administrative proceedings, including a public notice period and confirmation from INGEMMET and filing with the public registry.

Tim Kingsley, vice-president of exploration, commented: "Early fieldwork at the Rumi target has revealed a large, continuous alteration system with characteristics typical of high-sulphidation and lithocap environments, supporting the potential for a copper-gold porphyry system at depth. As we advance community partnerships toward drill permitting, we continue to refine our land position and prioritize high-impact drill targets across Sombrero."

The recognition of this new target strengthens Coppernico's district-scale exploration pipeline for the Sombrero project. Systematic mapping and sampling continue to refine multiple Cu-Au prospects, with continuing work aimed at defining drill-ready targets for the upcoming phase 2 drill program.
