John Black, Chief Executive Officer of Aldebaran, commented: “The 2025-2026 infill drilling program is well underway, and the results today demonstrate the consistency of mineralization at the Altar project. These holes will provide valuable information as we move toward a resource update and pre-feasibility study.”
Kevin B. Heather, Chief Geological Officer of Aldebaran, commented: “The current 2025-2026 infill drilling program, along with the 2024-2025 infill program, are critical for mineral resource conversion from the Inferred to the Measured and Indicated categories; neither of which are reflected in the current 2024 mineral resource estimate. Only Measured and Indicated resource blocks can be considered in a prefeasibility study and for the first time in the history of the Altar project, we will be declaring Proven and Probable reserves, which is a significant step in the derisking process for the project.”
Table 1 below shows detailed assays for all five holes. Figure 1 displays a plan map of the completed drill hole locations, while Figures 2 to 5 display cross sections of the holes reported herein. Holes with the suffix EXT are extensions of previously drilled holes.

| The grades are uncut. CuEq values were calculated using copper, gold, silver, and molybdenum. Metal prices utilized for the calculations are Cu = US$3/lb, Au = US$1,400/oz, Ag = US$18/oz, and Mo = US$10/lb. Recoveries used for the supporting metals found in the CuEq equation are as follows: Au = 50%, Ag = 51%, (based on historical metallurgical test work) and Mo = 70% (benchmarking from similar deposits). The formula utilized to calculate equivalent values is CuEq % = Cu % + (Au g/t * 0.34025) + (Ag g/t * 0.00446) + (Mo ppm * 0.00023). EXT indicates the hole was extended from a previously drilled hole. Intervals represent the true thickness of the deposit. | |||||||||
Project Update
The Company is actively drilling with six rigs on the property. The focus of the program is to complete both infill and geotechnical drilling that will be necessary for the upcoming pre-feasibility study. Upon completion of this year’s drilling, the Company will complete an updated mineral resource estimate, which is anticipated for Q3-2026. SRK Consulting Inc. has been hired to complete the MRE. The Company will also drill water wells this field season as part of its water-balance studies, and continues to collect environmental data, both of which are essential for the PFS and beyond. The Company has engaged SRK Consulting Inc. (Denver) as lead consultants for the PFS, with Knight Piesold as a subcontractor. The Company has also engaged Whittle Consulting Ltd to complete an optimization of the mine plan, which will be done in advance of developing the PFS. The analysis completed by Whittle will apply their integrated strategic planning methodology; an approach to long-term p lanning that evaluates and enhances the value of projects by considering all parts of the mining system across the value chain, all time periods, and all stakeholders. The scope of the PFS has broadened from what the Company had previously anticipated, and as such, the PFS is now expected to be completed in Q2/Q3-2027. The deadline for companies in Argentina to apply for the RIGI tax incentives and benefits has been extended by President Javier Milei to July 2027. The Company intends to submit a RIGI application in advance of the deadline but will now use the extended deadline to collect additional information before submission. It is anticipated that the Company will submit its application by Q1-2027.

New Break Resources Ltd. (CSE: NBRK) (OTCQB: NBRKF) (FSE: O91) has received results from the last four holes of a ten-hole, 1,996 metre summer drilling program in the Zavitz gold zone at the Company's 100% owned Moray gold project. In total, New Break has completed 5,372 metres of drilling in 32 drillholes in 2026. Moray is located 49 km southeast of Timmins, Ontario and 32 km northwest of the Young-Davidson gold mine operated by Alamos Gold Inc. Select results from the final four of ten holes drilled in the summer drilling program are presented below in Table 1, while drillhole collar locations are detailed in Table 2 in Appendix A.

(3) Drill core photos shown in Appendix B. Figure 1 – Newly Reported Drillholes NBR-26-29, 30 Figure 2 – Newly Reported Drillholes NBR-26-30, 31, 32 Note: The bottom of NBR-26-30 deviated southeast and is represented in both sections. Figure 1: Section B-B1 incorporates drillholes NBR-26-06, 07, 08, 25, 26, 27, 28, 29 and part of 30. Gold mineralization extends southeast into the syenite as exhibited in NBR-26-29. NBR-26-30 is identified in both sections A-A1 and B-B1 as the drillhole was collared along section A-A1 but deviated southeast, intersecting gold mineralization in the mafic volcanics in section B-B1. Figure 2: A-A1 incorporates drillholes NBR-26-03, 04, 05, 23, 24, 30, 31 and 32. NBR-26-31 exhibits gold mineralization both within the syenite (at the contact) and within a "flow breccia" within the hematite altered mafic volcanic at the contact. NBR-26-32 is typified by blocky faulted ground with lamprophyre dykes and gold mineralization in the hematite altered mafic volcanics in a brecciated quartz vein with angular syenitic fragments. William Love, Chief Executive Officer of New Break commented, "Ongoing drilling this summer in the Zavitz gold zone continues to deliver significant gold values, with gold mineralization intercepted in every drillhole. As depicted in Figures 1 and 2, gold mineralization has been encountered predominantly within the mafic volcanics. Importantly, drillholes NR-26-29 and NR-26-32, the deepest drilled to date, demonstrate that gold mineralization extends into the syenite to the southeast at the contact with the mafic volcanics." He further noted, "The intrusive-mafic volcanic contact in the Zavitz gold zone has a distinctive magnetic high. This could be reflective of the higher proportion of iron in these mafic volcanics, which is associated with the higher gold values. This same magnetic and IP signature has been identified elsewhere in areas also believed to be along the intrusive-mafic volcanic contact. Drilling these never before tested targets with the goal of identifying gold mineralization similar to that encountered in the Zavitz zone represents the potential for significantly expanding the Moray gold discovery. There is also the belief that the Zavitz zone could represent the first of a series of stacked mineralized gold zones, which would point to the potential for a much larger gold system at depth. We plan to test this through deeper drilling directly into the Zavitz zone." About the Moray Gold Project The Moray property is located in the heart of the Ontario Abitibi greenstone belt, 49 km southeast of Timmins surrounded by a number of significant gold producing companies and existing mills (see Figure 3). The Young-Davidson gold mine operated by Alamos Gold Inc., with its 8,000 tonne per day mill is the closest and within a short trucking distance of approximately 45 km by road from Moray. The understanding of gold mineralization at Moray continues to evolve with each round of drilling. The occurrence of gold mineralization extending into the syenite to the southeast of the Zavitz zone and in the deepest drillholes is noteworthy given the presence of syenite-hosted mineralization at Young-Davidison. More recent examination of the drill core also suggests that the gold mineralization discovered to date may resemble an intrusion related style of deposit like Agnico Eagle's Upper Beaver gold deposit east of Kirkland Lake, as opposed to a structurally hosted gold system. Both Young-Davidson and Upper Beaver host multi-million ounce gold deposits. Figure 3 – Moray Location Map: Surrounding Gold Producers and Upper Beaver Gold Project Technical Content and Qualified Person The scientific and technical information contained in this news release has been reviewed and approved by Peter C. Hubacheck, P. Geo, consulting geologist to New Break, and an independent Qualified Person as defined by National Instrument 43-101. Mr. Hubacheck certifies that this news release fairly and accurately reflects the technical information and data presented. New Break conducts its exploration activities in accordance with CIM Best Practices Guidelines. QA/QC Procedures QA/QC procedures were executed to ensure all work is conducted in accordance with best practices. All drill core was sawn in half with one half of the core prepared for shipment and the other half retained for future verification. All core is under watch from the drill site to the core processing facility. Drill core is BQTK size and sample intervals range from 0.5 metres to 1.0 metres in length. Commercially prepared certified reference material ("CRM") standards and blanks were inserted with each shipment at a rate of 1 QAQC sample in every 12 core samples. Samples from New Break's 2026 Moray drilling program were analyzed at Activation Laboratories in Timmins, Ontario, which is ISO 17025 certified, by 30-gram fire assay with atomic absorption finish. Any sample assaying greater than 10.0 g/t Au was re-assayed with fire assay gravimetric analysis. Grade composite intervals over core lengths are calculated using a weighted average grade with a cut-off grade of 0.3 g/t Au. Up to 1.0 m of internal dilution (consecutive interval below cut-off grade) are included within specific geologic domains and alteration assemblages, except as otherwise noted. The composites are constrained geologically by metasomatic alteration processes sourcing from the Fiset syenite intrusion and contact mafic volcanic rocks. Elevated gold values are coincident with hematite, silica, sericite and pyrite mineralization within structurally prepared brecciated corridors flanking the intrusion. Intervals are not true widths and no top cutting has been applied to the higher gold values. About New Break Resources Ltd.
