Prismo Metals samples up to 757 g/t Ag at Silver King

Executive Summary

• Prismo Metals announced exceptionally high‑grade silver, copper, lead, and zinc assays from the first batch of 23 samples taken at its Silver King project in Arizona.
• Two samples returned overlimit silver grades (619 g/t Ag and 511 g/t Ag); a polymetallic vein sample yielded 757 g/t Ag plus significant base‑metal percentages (1.5% Cu, 6.7% Pb, 11.5% Zn).
• The company is expanding its drill program by an additional ~1,000 m to test newly identified targets, including the polymetallic vein and a large replacement mineralization body on the Black Diamond claim.

Key Details

• Assay Highlights
• Sample #1 (Silver King shaft area): 619 g/t Ag (overlimit).
• Sample #2 (Silver King shaft area): 511 g/t Ag (overlimit).
• Polymetallic vein sample: 757 g/t Ag, 1.5% Cu, 6.7% Pb, 11.5% Zn.

• Replacement mineralization area – three samples with copper grades ranging from 1.11 % to 2.43 % Cu (overlimit).

• Drill Program Update

• Original plan: ~1,000 m targeting the upper half of the steeply dipping pipe‑like Silver King body and adjacent historic stockwork.
• Revised/second phase: additional ~1,000 m focused on newly identified targets (polymetallic vein, copper vein, replacement mineralization on Black Diamond claim).

• Plans submitted to U.S. Forest Service; some new sites will require further permitting.

• Quality Assurance / Quality Control

• Samples processed by SGS (pre‑prep in Tempe, AZ; analysis at Burnaby lab).

• QA/QC includes insertion of standard pulps and coarse blanks, plus use of SGS internal controls.

• Qualified Person

• Dr. Craig Gibson, PhD, CPG – Chief Exploration Officer & Director – reviewed and approved all technical disclosures per NI 43‑101.

• Project Context

• Silver King historic mine produced ~6 M oz Ag at up to 61 oz/ton; recent legacy samples (late‑1990s) showed up to 644 oz/ton Ag (18,250 g/t) and 0.53 oz/ton Au (15 g/t).
• Property lies ~3 km from the Resolution Copper JV (Rio Tinto/BHP), a world‑class unmined copper deposit (~1.787 B t @ 1.5% Cu).

Notable Quotes

• “The overlimit assays for silver highlight the high‑grade nature of both the mineralization around the Silver King mine and the recently encountered polymetallic vein…provides encouraging data for this style of mineralization.” – Dr. Craig Gibson, Chief Exploration Officer.
• “This work has expanded our geological thinking and resulted in the recognition of several new types of mineralization at the project, providing additional targets for exploration.” – Gordon Aldcorn, President, Prismo Metals.
