Prismo Metals Announces Assay & IP Results at Silver King

Prismo Metals has reported encouraging assay results from surface sampling at its Silver King project in Arizona, with the Crown porphyry target area yielding silver values up to 177 g/t along with complementary gold grades of 5.19 g/t and copper values of 0.37%. These results, combined with previously announced high-grade gold assays from December 2025, have established multiple high-priority drill targets across the Crown porphyry and adjacent Black Diamond replacement zones.

The company's recently completed pole-dipole IP survey has provided crucial three-dimensional subsurface data, revealing significant chargeability and resistivity anomalies that correlate with known mineralization. Notably, the Crown porphyry displays a chargeability anomaly that extends from surface to approximately 300 meters depth, suggesting substantial mineralization continuity. The IP data also confirms anomalies associated with the historic Silver King silver mine and the Black Diamond replacement body, validating the geological model and exploration strategy.

Prismo is advancing toward a fully funded 2,000-meter drill program focused initially on the historic Silver King mine site, with plans to test the upper portion of the steeply dipping pipe-like mineralized body. The company has received positive regulatory momentum, with the U.S. Forest Service determining that the proposed drill plan meets regulatory requirements and proceeding with environmental analysis under a Categorical Exclusion framework, indicating minimal anticipated environmental impact.

The Silver King project's location within a well-mineralized district that includes the Magma mine and Resolution copper deposit positions it within a proven mineral system. The combination of high-grade surface samples across multiple commodity targets (silver, gold, copper), supportive geophysical data, and advancing permitting creates a compelling exploration scenario. With the upcoming drill program representing the first modern systematic testing of these newly identified targets, Prismo appears well-positioned to potentially expand the known mineralization footprint beyond the historic mining areas.
