PRISMO METALS ANNOUNCES ASSAY & IP SURVEY RESULTS AT SILVER KING

Prismo Metals Inc. 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-sulphide veins hosted by the Crown porphyry (Table 1). 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 (see the news release dated Dec. 3, 2025).

"Prismo optioned Silver King with existing drill targets around the historically significant high-grade silver mine. Based on the geology and its location in a well-mineralized region, we believed that additional mineralization was also likely present. Our work in the second half of 2025 indicates that we were correct, and we now have exceptional drill targets at the Crown porphyry and adjacent Black Diamond replacement areas," stated Dr. Craig Gibson, chief exploration officer of the company. He added, "With the high-grade gold assays reported in December and the copper assays at the Black Diamond replacement, we now have a very significant precious metal and copper target at Silver King similar to other areas in this well-mineralized district that includes the Magma mine and the Resolution copper deposit."

"These additional assay results, along with the IP [induced polarization] survey information, continue to enhance and support our exploration thesis of the Silver King mine and surrounding areas," stated Gordon Aldcorn, president of the company. "This modern-day review has yielded additional drill targets and prospective structures to our program in this already very strategically located project."

IP survey

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 three-dimensional data for areas identified during the initial gradient array survey (see news release dated Dec. 3, 2025). 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 are 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 metres in depth.

Drilling update

Alain Lambert, chief executive officer of Prismo, commented: "The results announced today confirm the vast exploration potential at Silver King. While we look forward to drilling these new targets in the future, our plans remain unchanged. Our immediate priority is to undertake our fully funded drill program, as previously announced. This drill campaign will primarily focus on the historic Silver King mine site and will be about 2,000 metres. The objective is to test the upper half of the steeply dipping pipe-like Silver King mineralized body as well as potential mineralization adjacent to the dense stockwork that was the focus of historic mining."

Mr. Lambert added: "We are pleased with the steady progress on the permitting front. The collaboration of Forest Service officials demonstrates a clear commitment to supporting mining activities in Arizona."

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.

Quality assurance/quality control

Samples were analyzed by SGS, an internationally recognized analytical lab, with preparation at the Tempe, Ariz., facility and analyses at the Burnaby laboratory. Prismo inserts controls samples consisting of standard pulps and coarse blanks in the sample stream, and the lab also inserts control samples.

Qualified person

Dr. Craig Gibson, PhD, CPG, a qualified person as defined by National Instrument 43-01 regulations and chief exploration officer and a director of the company, has reviewed and approved the technical disclosures in this news release.
