Vancouver, British Columbia TheNewswire – December 3rd, 2025 Prismo Metals Inc. (‘ Prismo ‘ or the ‘ Company ‘) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to announce it has received assay results for samples recently taken at the Silver King Project from two exploration targets located on the east side of the property, namely the Black Diamond replacement target and the newly named Crown porphyry intrusion target (Fig. 1).

Figure 1 .  Map showing the location of the Black Diamond replacement and Crown porphyry intrusion exploration targets at the Silver King project.  Claim boundaries are shown in yellow.

The assays show high grade copper mineralization present at Black Diamond (Fig 1). The rock chip samples yielded generally high copper assays with several samples analyzing in excess of 1 % Cu and two samples in excess of 5 % Cu (Table 1, Fig. 2).  Gold is generally anomalous for the Black Diamond samples.

Rock chip samples from the Crown porphyry intrusion generally exhibited lead and zinc values with elevated silver and low copper and gold (Table 2).  Importantly, however, two samples of vein material from the stockwork target yielded high gold values of 4 and 5 g/t (Fig. 2). The mineralization in the stockwork veining at Crown provides impetus to complete additional exploration in the area.

IP Survey Update

The Company also has received the report for initial phase of its IP survey at Silver King.  The IP survey consisted of a gradient array to test for resistivity and chargeability anomalies at a depth of about 300m below the surface.

The IP survey shows low resistivity lows associated with the Black Diamond replacement body as well as the stratigraphically controlled Cu bearing replacements that extend toward the nearby Magma mine (Fig. 3).  A second nearly east-west trending resistivity low occurs in the central portion of the claim block and coincides with a hypothesized structure that may control the Black Diamond body and also may be important in the formation of the Silver King deposit.  This type of structure is similar to the Magma vein, the main mineralized structure at the high-grade Magma mine, and is a prime exploration target.

The IP survey also shows several chargeability anomalies that are presumably associated with disseminated sulfides, largely pyrite (Fig. 4).  The stockwork intrusion mentioned previously is associated with one of these chargeability anomalies and provides a second important exploration target with characteristics similar to mineralization at high structural levels in porphyry systems.  A second similar chargeability anomaly occurs nearby to the southwest in an area overlain by a mostly barren quartz diorite intrusive and may represent a similar blind porphyry target.

Based on the results of the initial IP survey, a follow-up pole-dipole survey to further define the anomalies from shallow to deeper levels along section lines is planned to be conducted in December.

Drilling Update

Alain Lambert, CEO 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 focus primarily on the historic Silver King mine site and will be for a minimum of about 1,000 meters. The objective is to test the upper half of the steeply dipping pipelike 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 will now proceed with the environmental analysis pursuant to 36 CFR 228(a)(5) in conformity with the National Environmental Policy Act (NEPA). This analysis will proceed 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.

Financing Update

Prismo also announced that further to its news releases dated October 20, 2025 and November 13, 2025, the Company has proceeded with an upsized second closing of its previously announced non-brokered private placement of units of the Company (‘ Units ‘) at an issue price of $0.10 per Unit (the ‘ Private Placement ‘). The second closing of the Private Placement was increased from 1,250,000 Units to the issuance of 1,650,000 Units for gross proceeds of $165,000 (the ‘ Second Tranche ‘). The Company previously announced a first closing of the Private Placement on November 12, 2025 for aggregate gross proceeds of $1,745,000. Due to strong investor demand, the Company has now raised aggregate gross proceeds of $1,910,000.

Each Unit consists of one common share in the capital of the Company (a ‘ Share ‘) and one common share purchase warrant of the Company (a ‘ Warrant ‘). Each Warrant entitles the holder to purchase one Share for a period of thirty-six (36) months from the date of issue at an exercise price of $0.175.

The Company intends to use the net proceeds of the Private Placement primarily for drilling at its Silver King project and for general corporate purposes. The Company expects to accept additional subscriptions of units in the coming days for an approximate amount of $125,000.

The Units issued pursuant to the Second Tranche are subject to a four-month hold period from the closing date of the Second Tranche under applicable Canadian securities laws, in addition to such other restrictions as may apply under applicable securities laws of jurisdictions outside Canada.

In connection with the Second Tranche, the Company issued an aggregate of 68,000 finder’s warrants (the ‘Finder’s Warrants’ ) and paid finder’s commissions of $6,800 to a certain qualified finder. Each Finder’s Warrant is exercisable for a period of twenty-four (24) months from the date of issuance to purchase one Share at a price of $0.10. In addition, the Company paid a cash fee of $2,000 to a financial advisor.

The securities being issued in connection with the Second Tranche have not been and will not be registered under the U.S. Securities Act and may not be offered or sold in the United States, or to, or for the account or benefit of, U.S. persons or persons in the United States, absent registration or an applicable exemption from the registration requirements. This press release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in any State in which such offer, solicitation or sale would be unlawful.

QA/QC

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