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 channeling 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:
Article content
- Tipicancha: 1 km by 2 km epithermal alteration with Cu-bearing zones returning up to 22 m of 0.65% Cu, including 10 m of 1.14% Cu (true widths unknown, see Coppernico press release dated May 21, 2025).
- Macha Machay: Newly mapped 4 km by 1 km alteration zone supported by broad geochemical anomalies (additional exploration results pending, see Company press release dated August 18, 2025).
- Ccello: Approximately 2 km by 1.5 km silver-kaolinite lithocap with silver mineralization associated with quartz-alunite alteration and massive silica structures (see press release dated September 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 multi-phase magmatic and hydrothermal activity, suggesting the presence of deep-seated, crustal-scale structures and potential for concealed porphyry centers 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 US$3 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, VP 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 ongoing work aimed at defining drill-ready targets for the upcoming Phase 2 drill program.
