Prismo Metals Inc. announced it has received final assay results for samples taken at the Silver King Project from the Crown porphyry target area located on the east side of the property. Overlimit silver assays have been received for the samples taken in late 2025, showing high grade silver mineralization associated with quartz-sulfide veins hosted by the Crown porphyry. These assays provide evidence for a high-priority drill target, especially when taken in conjunction with the high gold assays reported previously for the stockwork intrusion.
The Company also completed a pole-dipole IP survey over a part of the Silver King project in December 2025. This survey was designed to provide some additional 3-dimensional data for areas identified during the initial gradient array survey. This new survey confirmed the presence of important chargeability and resistivity anomalies at the Silver King project.
The Silver King silver mine appears to be associated with a large low resistivity anomaly located on the contact of the Silver King diorite porphyry. There is also low resistivity anomalies associated with the Crown porphyry and near the replacement mineralization at Black Diamond. The highest chargeability anomalies appear to be associated with the altered country rocks along intrusive contacts, but a chargeability high is also associated with the Crown porphyry stockwork intrusion.
The anomaly associated with the Crown porphyry is particularly interesting and can be traced from shallow levels to about 300 meters in depth. Prismo recently announced that the Forest Service, the federal surface land management entity for Silver King, had determined that the Company's proposed drill plan meets the regulatory requirements for processing, and that such plan is complete, as described in the regulations at 36 CFR 228.4(c). The Forest Service is currently proceeding with the environmental analysis pursuant to 36 CFR 228(a)(5) in conformity with the National Environmental Policy Act (NEPA).
This analysis is proceeding as a Categorical Exclusion, the lowest level of environment reviews applicable to projects that are not expected to have a significant effect on the environment, such as Silver King.
