Highlights

• DD03: 24 meters averaging 0.95 g/t AuEq, plus 0.29% Cu

• Elevated lead: Multiple intersections of elevated lead values were intersected in all three holes

• Elevated zinc: Multiple intersections of elevated zinc values were also intersected in all three holes

• Highest-grade intercepts:

  • DD01: 4 Meters of elevated AuEq 2.85 g/t, plus 3.23% Pb and 11.90% Zn

  • DD02: 29 Meters of 1.89 g/t AuEq

Management Comments

Norsemont CEO Marc Levy commented:

"We are pleased with the positive gold and elevated base metal results from the first three holes of the 2025 Phase 3 drill program. These long gold equivalent intercepts are above the current sulfide resource grade, highlighting the potential to upgrade the resource volume and average grade. We are also encouraged by the geological team's growing understanding of the controls on higher-grade mineralization. The data indicates the potential for a porphyry system. The presence of the elevated base-metal mineralization is particularly intriguing, and we look forward to receiving further re-assay results and integrating those data into the broader Choquelimpie geological model. These significant results add to our increasing confidence in the potential for substantial high-grade gold zones at depth and along strike beneath the existing open-pit resource."

The Phase 3 Drill Program

Choquelimpie drill samples have been analyzed for silver, copper, lead and zinc using the Inductively Coupled Plasma (ICP) analytical method. Initial assay values for some samples were reported as "over-limit," meaning the ICP method is not accurate above a stated maximum concentration. These samples have been re-assayed by atomic absorption spectrometry (AA), a method which is accurate at the higher concentration levels. The AA results have been received for much of the Phase 3 (2025) drilling, with distinct zones of silver-lead-zinc, lead-zinc and copper mineralization being intersected. Continuous base-metal intercepts, along with the corresponding gold and silver concentrations, are summarized in Table 1. The primary gold intercepts, previously reported in a Norsemont press release dated 24 February 2026, are also included. Gold-equivalent (AuEq) values are now also reported (Table 1).

Table 1

Note: true thicknesses of mineralization are unknown

Base-metal values are low for the DD-01 (Vizcacha Zone) primary gold intercept (0-109 meters depth). However, an intercept of silver-lead-zinc mineralization is present further down the hole (130 - 180 meters). Gold, within this interval, is also elevated (1.40 g/t) at 165 - 169 meters.

Base metal values are also low for the DD-02 (Vizcacha Zone) primary gold intercept (0-94 meters depth). Zones for each of Ag-Pb-Zn (211 - 219 meters depth) and Pb-Zn (230 - 238 meters depth) mineralization have been intersected by the hole.

Anomalous copper mineralization (0.21% average) is coincident with the upper gold intercept for DD-03 (Choque Zone). In addition, primarily Pb-Zn mineralization has been intersected at downhole depths of 80 - 87 and 119 - 143 meters.

The mineralogical relationship between the precious- and base-metal mineralization will be assessed as part of metallurgical studies planned to be conducted on sulfide materials later in 2026. The three-dimensional spatial relationships between the various mineral intercept types will also be analyzed once additional data has been received. The results of these studies, in conjunction with geological and geophysical information, should provide important data points to aid in interpretation of the evolution of the Choquelimpie hydrothermal mineralizing system.

The Phase 3 drill campaign at Choquelimpie has successfully evaluated the down-dip extensions of higher-grade gold mineralization (>1 gram/tonne Au) hosted within hydrothermal breccia zones (Figure 1). Seven (7) core holes, totaling approximately 1650 meters have been completed. Details of this program are shown on Figure 1 and Table 2.

All split drill core samples for the drilling have been shipped to Activation Geological Services SpA for geochemical analysis. The samples have been prepared at the AGS facility in Antofagasta Chile and are being analyzed at the AGS geochemical laboratory, in Coquimbo, Chile. The laboratory has an ISO 17025 certification. The gold grades are being determined by fire assay (AGS code AU-FA30). Drill intervals that have some degree of oxidation are also being analyzed by the cyanide-soluble gold method (AUCN).

Samples have also been analyzed for 60 elements, including silver, by mass spectrometer (MS TD60). In addition, silver and specific base metals have been re-assayed by atomic absorption (AGS code 4ACID-AAS) for samples where the initial value for a particular element is greater than the limit of accuracy ("over-limit") for that method. The overlimit value for: silver (Ag) is 100 parts per million (ppm), copper (Cu) is 10,000 ppm, lead (Pb) is 5,000 ppm, and zinc (Zn) is 10,000 ppm.

Examination of Norsemont's 2021 core drilling assay results has determined that values for multiple individual samples from that program have also been reported with over-limit values. These samples, where material remains available, will also be re-assayed according to the protocols being utilized for the Phase 3 drill program.

Standard and blank samples have been inserted at a frequency of one each for every 20 drill samples.

Gold-equivalent (AuEq) values have also been calculated according to the following formula: AuEq (g/t) = Au (g/t) + Ag (g/t) * Ag price/Au price * Ag recovery/Au recovery; where Au price = USD 4,000/oz, Ag price = USD 62/oz, Au rec = 88%, and Ag rec = 87% (recoveries based on historical flotation test results).

The Phase 3 exploration program was supervised by Roman Flores, a Persona Calificada (Q.P.) with the Commission Minera Chile.
