Wojtek Wodzicki, President and CEO, commented, “Drillhole DPDH077 is a good reminder that the Jupiter Zone, which was first intersected by the Lunahuasi discovery drillhole, is not to be overlooked. We have fewer holes into Jupiter than Saturn or Mars, but several intersections across an area of 400 x 500m highlight the potential of this third major zone within the overall Lunahuasi deposit. Holes DPDH069 and DPDH072 are step out holes on Saturn, expanding the zone by over 100m up-dip and down-plunge, respectively. Saturn remains open in all directions. Our team is now focused on updating our geological interpretation with the information gathered during the Phase 4 drill program and developing a robust geological model which will guide our planning for Phase 5 drilling.”

Table 1: Significant Intersections

DPDH069 was drilled at an azimuth of 275^o and a shallow dip of -31^o to test the Saturn Zone up dip from holes DPDH021 and DPDH057. The zone was intersected over 145m, from 518m to 663m, and remains open between this intersection and surface, just over 300m above.

DPDH071 was drilled from the same platform as DPDH044, DPDH051 and DPDH059 at an azimuth of 181^o and a dip of -50^o to drill along the Saturn Zone above those holes. The 573.4m long mineralized interval from 274.6m to 848.0m reflects part of the strike length of the zone, cutting diagonally across it and is comprised of moderate grade disseminated and stockwork mineralization cut by several much higher-grade veins as indicated by the sub-intervals.

DPDH072 was a step out hole down plunge from DPDH055 and DPDH056, with an azimuth of 293^o and a dip of -67^o. The hole intersected a shallow zone starting at 193.0m and extending over 63.7m which may correlate with the first zone intersected in the adit geotechnical hole (DPGT004) 300m to the northeast. This zone included a higher-grade intersection of 8.08% CuEq over 11.4m and is open to the northeast. The hole then intersected Saturn beginning at 639.0m and continuing for at least 207.0m to 846.0m. As noted below, the western contact is often ambiguous as mineralization, punctuated by high-grade veins, continues to at least the end of the hole at 941.0m.

DPDH074 was another shallow hole drilled southwesterly towards the top of the Saturn Zone, at an azimuth of 234^o and a dip of -29^o, intersecting the zone 80m below DPDH069. The Saturn Zone was intersected over 121.5m, from 408.0m to 529.5m, however the grade was lower than surrounding holes, primarily due to the number and width of high-grade veins intersected.

DPDH077 was drilled at an azimuth of 303^o and a dip of-45^o to test the Jupiter Zone down dip from holes DPDH009 (62.00m at 6.98% CuEq; 3.75% Cu, 3.43 g/t Au, 83.1 g/t Ag) and DPDH010 (62.60m at 5.84% CuEq; 3.10% Cu, 2.09 g/t Au, 138.3 g/t Ag). The hole intersected a thick massive sulphide vein at 326m with exceptional grades, extending the zone by about 100m from the intersection in DPDH009 and 70m from the intersection in DPDH010. It remains open in several directions from this new intersection.

Discussion

Hole DPDH077 extends the Jupiter Zone and highlights the very high grades present within this structure. Jupiter has been drilled by fewer holes than Mars or Saturn, primarily due to geometry challenges in targeting the zone from surface. In addition to holes DPDH009 and DPDH010 noted above, significant Jupiter intersections include DPDH007 (13.7m at 8.10% CuEq; see News Release dated July 4, 2023) and DPDH043 (46.80m at 9.55% CuEq; see News Release dated July 2, 2025) 330m down dip and 330m to the northeast respectively. Together, these intersections indicate significant size potential for Jupiter and targeting this will be a priority for the Phase 5 program.

Holes DPDH069, 71, 72 and 74 intersected the Saturn Zone across a wide area, helping to outline its dimensions and grade distribution. Our current interpretation is that Saturn is a large, structurally controlled zone of disseminated and stockwork mineralization cut by numerous high to very high-grade veins of various orientations. The eastern contact is quite sharp, marked by a distinct increase in mineralization with a consistent change to advanced argillic alteration. The western contact is more difficult to define, as there is no similar sharp cutoff in mineralization or alteration, just an apparent decrease in the density of the high-grade veins as the system transitions into disseminated and stockwork mineralization. This change is thought to be in part due to a change in lithology from diorite porphyry in the east to rhyolite and andesite volcanic rocks in the west, with the Saturn Zone occurring near to the contact.

The shallow, high-grade zone in hole DPDH072, from 193.0m to 256.7m, may be part of an emerging new zone to the east of Saturn. This zone is tentatively correlated with DPGT004 (9.10m at 9.92% CuEq; 6.36% Cu, 3.47 g/t Au, 116.9 g/t Ag; see News Release dated April 30, 2026) 300m to the northeast and DPDH041 (8.30m at 12.38% CuEq; 7.77% Cu, 4.01 g/t Au, 191.2 g/t Ag; see News Release dated July 2, 2025) 100m to the southwest and remains open in all directions.

Phase 4 Progress

The Phase 4 program is now complete, with a total of 27,318m drilled and 32 holes completed. Assay results from the final five holes will be released once assays are received, analyzed, and confirmed by the Company.

Qualified Persons and Technical Notes

The scientific and technical disclosure included in this news release have been reviewed and approved by Bob Carmichael, B.A.Sc., P.Eng. who is the Qualified Person as defined by NI 43-101. Mr. Carmichael is Vice President, Exploration for the Company.

Samples were cut at NGEx’s operations base in San Juan, Argentina by Company personnel. Diamond drill core was sawed and then sampled in maximum 2-meter intervals, stopping at geological boundaries. Core diameter is a mix of PQ, HQ and NQ depending on the depth of the drill hole. Samples were bagged, tagged, and packaged for shipment by truck to the ALS preparation laboratory in Mendoza, Argentina where they were crushed and a 500g split was pulverized to 85% passing 200 mesh. The prepared sample splits were sent to the ALS assay laboratory in Lima, Peru for copper, gold and silver assays, and multi-element ICP. ALS is an accredited laboratory which is independent of the Company. Gold assays were by fire assay fusion with AAS finish on a 30g sample (Au-AA23). Samples returning > 10 g/t gold were then reanalyzed by fire assay with gravimetric finish on a 30g sample (Au-GRA21). Copper and silver were assayed by atomic absorption following a 4-acid digestion. Samples were also analyzed for a suite of 48 elements with ME-MS61 plus mercury and a sequential copper leach analysis was completed on each sample with copper greater than 500ppm (0.05%). Sequential copper analysis involves the sequential leaching of the sample by acid, followed by a cyanide solution. It can be used to differentiate copper speciation, with copper oxide minerals leachable with acid and high-sulphidation copper minerals (enargite, chalcocite, covellite) leachable by cyanide. The residual copper remaining following the sequential leaches is typically contained in chalcopyrite and bornite. Copper and gold standards as well as blanks and duplicates (field, preparation, and analysis) were randomly inserted into the sampling sequence for Quality Control. On average, 10% of the submitted samples are Quality Control samples. No data quality problems were indicated by the QA/QC program.
