Nobel updates Cuprita, Pampa Austral drilling and Anis project, Chile

TORONTO, June 15, 2026 (GLOBE NEWSWIRE) -- Nobel Resources Corp.  (TSX – V: NBLC; OTCPK: NBTRF) (the “Company” or “Nobel”) announces that the company has completed drilling on the Pampa Austral project and drilling has commenced on the Cuprita project (“Cuprita” or the “Project”). At Cuprita, which remains the core project for Nobel, the geophysical and remote sensing surveys along with detailed geological mapping and compilation have identified areas within the large lithocap with alteration mineral assemblages that are characteristic of higher temperature parts of porphyry copper systems, including intense albitization and destruction of biotite minerals. These areas correspond with strong Induced Polarization (IP) chargeability anomalies and are now the focus of the drilling.

The Company will announce the results of its drilling program at Cuprita once the program is completed and the results are received from the laboratory. According to Vernon Arseneau, CEO and Director of Nobel, “Based on my decades of experience in this region, we rarely see such intensely altered porphyry systems with only the few drill holes completed by Nobel and no other drilling. These are large complex systems and require a systematic approach and some persistence to solve geometry.” The Company has decided to terminate the option agreements for the Anais and Pampa Austral projects, effective June 15, 2026.   At Pampa Austral, two drill holes were done in an effort to repeat historical results reported by Farwest Mining in 2024 (see the Company’s press release dated May 15, 2026).

Unfortunately, drilling failed to repeat the copper results reported by Farwest at the time. The Company compiled historical results and had located two drill pads on the ground that appeared to be the ones reported earlier but drilling did not encounter the same geological environment or intersect high copper mineralization. The Induced Polarization anomaly (IP) present in the same location has also been explained by the presence of stringers and disseminations of pyrite over several meters of core length.

At the Anais project, field work by Nobel geologists encountered a number of previously unreported drill hole casings on the property, close to the reported high-grade intersection reported by Farwest Mining. This limits the potential for a significant copper discovery and the Company has decided not to continue exploring this prospect.

According to Vernon Arseneau, CEO and Director of Nobel, “The results obtained at Pampa Austral and Anais have downgraded the potential at those projects in our estimation, however, we remain committed to continue exploration at Cuprita and Janett. Both projects have strong exploration potential and we intend to focus on exploring these during the coming months.” Figure 2: Location of the Pampa Austral, Janett, Anais and Cuprita Projects relative to copper deposits Please note information regarding adjacent properties is provided for context only and is not necessarily indicative of the mineralization, grade, continuity or potential of the Project.

Quality Assurance and Quality Control (QA/QC) Sampling is conducted in a manner designed to allow appropriate averaging and statistical analysis of the data for exploration evaluation and potential future resource estimation. Industry-standard QA/QC procedures are implemented throughout the sampling and analytical process, including the systematic insertion of certified reference materials, blanks and duplicate samples to monitor laboratory performance and analytical accuracy. Drill core samples are typically collected over intervals ranging from 1 to 2 metres, depending on geological boundaries.

Shorter sample intervals are avoided whenever possible to maintain consistency and representativity of the sampled material. Prior to sampling, the drill core is geologically logged and photographed to create a high-resolution photographic record. Core samples are then split along the core axis using an electric rock saw by trained company technicians.

One half of the core is sent for analysis while the remaining half is retained on site for reference and verification. As part of the QA/QC program, one certified reference standard is inserted every 20 core samples. Additionally, one coarse blank, one fine blank and one internal duplicate sample are inserted approximately every 50 core samples to monitor contamination, analytical precision and laboratory performance.

To ensure sample security and compliance with NI 43-101 chain-of-custody standards, samples are placed in sealed rice bags with numbered security tags at the project site. Samples are then transported by company personnel via truck to the analytical laboratory. Custody and transfer of the samples always remain under the responsibility of company personnel.

Sample preparation and analytical work are carried out by Andes Analytical Assays, an independent certified laboratory.
