"The Los Chapitos project is interpreted to belong to the northwest extension of the upper Jurassic metallogenic belt defined in Chile, which hosts porphyry copper deposits ("PCD"), iron-oxide-apatite deposits ("IOA"), copper-silver deposits ("Cu-Ag"), iron-oxide-copper-gold deposits ("IOCG") and epithermal systems. This belt contains several Cu-Ag deposits, from south to north such as Las Luces, Carolina de Michilla, and Mantos de La Luna, that are hosted by the La Negra ("black") formation in Chile, which is geologically equivalent to the Chocolate formation in Peru. The recent drilling results validate the geological model at the Adriana, Mirador, and Lourdes zones, and demonstrate that the interpreted Cu-Ag mineralized bodies have continuity along strike to the north and south and extend at depth," said Jose Bassan, consulting geologist.

"Over the past year, exploration efforts have focused on understanding the main copper corridor along the Diva northwest trend. This work included systematic 1:2,000 scale geological mapping, re-logging thousands of metres of drill core, and interpreting numerous geological cross sections, incorporating lithology, alteration and mineralization. These activities have resulted in a robust geological model," said Yoshikazu Fujimoto, Nittetsu's exploration manager.

The objective of Phase 1 of the drilling campaign was to validate the geological model and to demonstrate the extension and continuity of the interpreted mineralized breccias hosting the Cu-Ag, both to the north and south, and at depths deeper than the previously known limits.

Geological Discussion

The recently completed 1,036.25 metre drilling program has increased total drilling at the Los Chapitos Copper Project to 28,660 metres, further strengthening the Project's growing exploration database. Notably, approximately 91% of all historical drilling has been focused along the highly prospective Diva trend, extending approximately 7 km, underscoring the Company's strategic emphasis on this important copper corridor.

In addition to the Diva trend, other major structural corridors, such as La Estancia and Atajo, extending approximately 18 km and 8 km, respectively, remain significant, underexplored, and present compelling targets for future drilling campaigns.

Drilling along the Diva northwest trend has successfully recognized a new mineralized body such as Mirador and validated the interpreted mineralized bodies at Adriana, Lourdes, and Enjambre, highlighting the upside potential of the project. (Figure 1).

Eight drill holes were completed along the highly prospective Diva trend corridor (holes DCH-123, DCH-124, DCH-125, DCH-126, DCH-127, DCH-128, DCH-129, and DCH-130), testing the Mirador, Adriana, Enjambre, Maqui, Piloto and Lourdes targets.

The project area is underlain by volcanic rocks of the Jurassic-aged Chocolate Formation, which are intruded by monzodioritic and dioritic hypabyssal bodies. Mineralization is primarily controlled by Diva, Atajo, and La Estancia faults that act as conduits for mineralizing copper fluids, together with secondary faults, such as Lourdes, Maqui and Claudia faults.

Copper mineralization is hosted within breccias and mantos related to first, second and third order faults and occurs near the surface as oxide minerals, including malachite, chrysocolla, and brochantite, associated with copper wad, and at deeper locations sulfide mineralization is dominated by chalcopyrite and some bornite.

Mirador Target

At the Mirador target, drill hole DCH-123 intersected 8.7 m @ 0.45% Cu & 8.65 g/t Ag. Mineralization is hosted within breccias developed in intrusive rocks and is characterized predominantly by green copper oxides, including malachite and brochantite, together with copper wad (Figure 2).

The mineralization intercepted corresponds to surface outcrops previously reported by the Company (see news release dated July 16, 2025). The exploration potential at Mirador remains open, extending over 200 m to the northwest of the Adriana sector, supported by the continuity of surface mineralization and its confirmation at depth in drill hole DCH-123.

Adriana Target

At the Adriana target, drill holes DCH-124 and DCH-125 intersected significant copper mineralization. Drill hole DCH-124 intercepted 17.6 m @ 0.85% Cu & 2.48 g/t Ag, while DCH-125 intersected 83.5 m @ 0.94% Cu & 10.40 g/t Ag (Figure 3). Mineralization is dominated by copper oxides (malachite-chrysocolla) near surface, transitioning at depth to high-grade copper mineralization associated with disseminated sulfides, mainly chalcopyrite and bornite. These sulfides are hosted in volcanic rocks brecciated by hydrothermal fluids ascending along the Diva Fault (Figure 3). This vertical transition from oxides to sulfides confirms a well-preserved, deep high-grade system, extending the exploration potential beyond 200 m depth.

The Diva Fault is a key structural control on mineralization, and recent drilling has validated the high prospectivity of this target, opening additional exploration potential both to the southeast and northwest of the Adriana area.

Enjambre, Maqui, and Piloto Targets

At Katty's satellite targets (Enjambre, Maqui, and Piloto), a single drillhole was executed on each target. At these targets, the mineralization is hosted in volcanic rocks intruded by hypabyssal bodies.

At Enjambre, drillhole DCH-126 intercepted 17.8 m @ 0.20% Cu & 2.55 g/t Ag related to copper oxides such as malachite mainly and copper wad. The Maqui fault is a secondary fault related to Diva northwest trend.

At the Maqui target, drillhole DCH-127 intercepted 4.2 m @ 0.19% Cu & 4.5 m @ 0.13% Cu related to copper oxide mineralization, mainly malachite and copper wad. Mineralization is structurally controlled by the Claudia fault, a secondary fault related to Maqui fault.

At the Piloto target, drillhole DCH-128 intercepted 13.1 m @ 0.15% Cu & 4.6 m @ 0.23% Cu, mainly copper oxides.

The Enjambre, Maqui, and Piloto targets showed limited copper intercepts; however, the presence of mineralization, albeit at a lower grade, confirms that these areas are mineralized and controlled by secondary structures associated with the Diva northwest fault system. This confirms the extension of mineralization to the southeast, a covered area that has not yet been explored.

Lourdes Target

At Lourdes, two drill holes were drilled. drill hole DCH-129 intercepted 63.3 m @ 0.62% Cu & 1.6 g/t Ag related to green copper oxide minerals, such as malachite, chrysocolla, and brochantite, with localized high-grade zones. The mineralization occurs in a breccia hosted by epiclastic volcanic rocks intruded by hypabyssal bodies (Figure 4).

The Lourdes north-south fault acted as a conduit for hydrothermal fluids in order to form mineralized breccia bodies. Drill hole DCH-129 intersected a mineralized breccia, in contrast, drill hole DCH-130 didn´t reach the Lourdes fault and is barren.

Picture 1. Example of high-grade copper mineralization in drillhole DCH-129. The 73 to 76-metre interval has an average grade of 2.13% copper.

These results validate the Project's exploration potential; the mineralization is hosted in breccias controlled by the Diva northwest fault, Lourdes northsouth fault and other mapped faults of second and third order. Drilling has validated the vertical continuity of mineralization from the surface, demonstrating that the system remains open and preserved at depth. Additionally, there are untested targets along the Diva trend and along prospective La Estancia fault and the Atajo faults trend. Based on these advances, the Company plans to begin a second phase of drilling in March, focused on Sombrero Blanco target along the La Estancia fault, subject to receiving a modification to the current permit, and continued targets along the Diva trend. The objective is to validate the extension at depth of the stratabound Cu-Ag mineralized zones recognized at surface.

Sampling and Assay Procedures

During this campaign, eight drillholes were completed. Core has been logged and sampled at the Company's facilities in the town of Chala, 15 km from the project. Industry standard chain of custody and QA/QC practices are followed with samples sent to Lima where they are analyzed by ICP-MS at ALS Chemex Labs' facility. The Camino geological team complied with the written internal QA/QC procedures, where the insertion of blank samples, certified international standards (pulps) and duplicates, met the objectives and acceptable results.
