NOBEL PROVIDES UPDATE ON CUPRITA PROJECT, CHILE

Nobel Resources Corp. has released results from recent drilling at its Cuprita project and received final results from the recently completed IP survey on the project.

At Cuprita, drill hole CUP-006 intersected a short section of 3,237 parts per million copper (228 to 229 metres), within a 21-metre anomalous copper section averaging 504 parts per million copper (208 to 229 metres). From 395 to 400 metres, a second anomalous section returned 0.115 per cent copper.

Drill hole CUP-006 has the strongest alteration of all holes drilled to date and contains very low pyrite, indicating that it is away from the pyrite halo and getting closer to the mineralized centre. Recently obtained 3-D inversion data have shown that drilling to date has been focused on the edges of the main chargeability anomalies and the next phase of drilling will focus on follow-up of this newly identified target area.

The final geophysical results from Quantec's pole-dipole induced polarization survey (please see the company's news release dated April 23, 2026, for further details), which were received after CUP-006 was drilled, indicate that the core of the anomaly lies east of the hole collar. The 3-D inversion model highlighted a large and continuous chargeability anomaly that corresponds very well with the mapped lithocap and extended the favourable target area to the south and east of the area where exploration has been concentrated to date. The anomaly south of the previously known outcrops of the lithocap is under shallow cover and has opened a new area of potential mineralization. The total area of corresponding lithocap and IP chargeability anomaly now extends over an area of 1.0 kilometre by 3.0 kilometres along a north-northwest elongated axis.

A horizontal chargeability slice extracted from the Quantec 3-D DCIP (direct-current induced polarization) inversion model at the 1,600-metre elevation provides a plan-view representation of the distribution of subsurface chargeability across the Cuprita project. The slice was generated from the fully integrated 3-D inversion of nine east-west DCIP profiles (2.6 kilometres each), complemented by historical DCIP data, allowing chargeability responses to be evaluated as continuous volumetric features rather than as isolated 2-D sections. At this elevation, two major chargeability centres are clearly defined and spatially coincide with the hyperspectral lithocap footprint recognized at surface. Their geometry, alignment and continuity suggest they may represent connected expressions of a single, large hydrothermal system developed along the project's dominant N30 degrees W structural corridor. This interpretation is further supported by the close spatial correlation between the chargeability anomalies, widespread hydrothermal alteration mapped at surface and the porphyry-related mineralization intersected in drilling. The continuity observed in the 3-D chargeability model significantly reduces the uncertainty inherent in interpreting individual 2-D sections, providing compelling evidence that the surface lithocap exposures and the underlying chargeability responses are manifestations of a laterally extensive porphyry-related hydrothermal system.

According to Vernon Arseneau, chief executive officer and director of Nobel: "The IP survey has been very useful in extending the exploration potential of Cuprita, especially to the east and south, where there is very little outcrop. We look forward to continue exploring this highly prospective target."

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 one to two 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 National Instrument 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 by 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.
