Prismo Metals Announces Assay & IP Survey Results at Silver King

Executive Summary
- Final assay results from the Crown porphyry target at Silver King show high‑grade silver (up to 177 g/t Ag) and notable gold, copper and base‑metal values, confirming a new high‑priority drill target.
- A pole‑dipole IP survey completed in Dec 2025 identified strong chargeability and low‑resistivity anomalies associated with the Crown porphyry and Black Diamond replacement bodies, supporting the exploration thesis.
- Management reaffirmed its fully funded 2,000 m drill program focused on the historic Silver King mine area and reported progress on permitting with Forest Service approval for a categorical exclusion.
Key Details

- Sample 544561 – 2 m width: 0.02 g/t Au, 177 g/t Ag, 0.07 % Cu, 0.37 % Pb, 0.02 % Zn.
- Sample 544563 – 0.5 m width: 0.03 g/t Au, 176 g/t Ag, 0 % Cu, 0.09 % Pb, 0.01 % Zn.
- Sample 544591* – 1 m width: 5.19 g/t Au, 46.44 g/t Ag, 0.05 % Cu, 0.21 % Pb, 0.06 % Zn.
-
Sample 544592* – 1 m width: 4.06 g/t Au, 13.97 g/t Ag, 0.02 % Cu, 0.10 % Pb, 0.07 % Zn.
-
Previous high‑grade gold assays reported on Dec 3 2025 for the stockwork intrusion are reinforced by these new silver results.
-
IP Survey (Dec 2025):
- Detected a large low‑resistivity anomaly at the contact of the Silver King diorite porphyry.
-
Additional low‑resistivity and chargeability anomalies linked to Crown porphyry and Black Diamond replacement bodies, extending from shallow levels to ~300 m depth.
-
Drilling Program:
- Fully funded 2,000 m drill campaign targeting the historic Silver King mine zone and adjacent steeply dipping mineralized pipe.
-
Objective: test upper half of the pipe and potential mineralization near dense stockwork zones.
-
Permitting Update:
- Forest Service confirmed that the proposed drill plan meets regulatory requirements (36 CFR 228.4(c)).
-
Environmental analysis proceeding as a Categorical Exclusion under NEPA, indicating minimal expected impact.
-
QA/QC: Samples processed by SGS (Tempe, AZ prep; Burnaby lab analysis) with standard control samples inserted throughout the workflow.
-
Qualified Person: Dr. Craig Gibson, PhD., CPG – Chief Exploration Officer and director – reviewed and approved all technical disclosures.
