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.

and Crown areas at Silver King.

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.

Group Eleven Resources Corp. (TSXV: ZNG,OTC:GRLVF) (OTCQB: GRLVF) (FSE: 3GE) (‘Group Eleven’ or the ‘Company’) is pleased to announce the latest two step-out drill holes from its Ballywire discovery (‘Ballywire’) at the 100%-owned PG West Project (‘PG West’), Republic of Ireland.

Highlights:

• 25-3552-47 (approx. 100m step-out SSE of 25-3552-40, initial test of the Deeper Cu-Ag target; announced 22-Sep-25) intersected four zones of mineralization, including:
  • New Mineralized Zone (South) – Waulsortian Hosted (starting from 313.1m downhole)
  • 20.3m of 2.6% Zn+Pb (1.5% Zn and 1.1% Pb), 6 g/t Ag, including
  • 7.3m of 5.2% Zn+Pb (2.5% Zn and 2.7% Pb), 10 g/t Ag, including
  • 3.8m of 7.3% Zn+Pb (3.7% Zn and 3.6% Pb), 14 g/t Ag, including
  • 1.9m of 10.7% Zn+Pb (5.7% Zn and 5.0% Pb), 19 g/t Ag
  • New Mineralized Zone (South) – Base of Waulsortian (starting from 355.9m downhole)
  • 2.6m of 2.7% Zn+Pb (0.1% Zn and 2.5% Pb) and 19 g/t Ag, including
  • 0.8m of 6.7% Zn+Pb (0.3% Zn and 6.5% Pb) and 37 g/t Ag
  • Deeper Cu-Ag Zone (starting from 490.7m downhole)
  • 11.3m of 0.26% Cu and 8 g/t Ag, including
  • 4.7m of 0.46% Cu and 14 g/t Ag, including
  • 1.8m of 0.83% Cu and 24 g/t Ag
  • Deeper Cu-Ag Zone (starting from 616.6m downhole)
  • 9.4m of 0.25% Cu and 7 g/t Ag, including
  • 3.7m of 0.32% Cu and 8 g/t Ag, including
  • 0.8m of 0.62% Cu and 16 g/t Ag

‘Today’s results represent a positive surprise given we were not expecting robust Zn-Pb-Ag mineralization south of the main discovery trend at this particular location,’ stated Bart Jaworski, CEO. ‘In addition to successfully extending significant Deeper Cu-Ag mineralization down dip by over 200m from previous drilling, today’s hole intersected strong Zn-Pb-Ag mineralization in a new part of the discovery. Long theorized, new zones of mineralization parallel to the main discovery trend at Ballywire were evidenced this September by hole 25-3552-44 which discovered a new Cu-Ag bearing feeder structure to the north of the main discovery. Today’s results show a similar situation, but to the south, enhancing the potential for at least two additional mineralized zones. If borne out, this greatly expands Ballywire’s tonnage potential.’

‘Driven by new zones of mineralization, growing momentum at our Deeper Cu-Ag zone and the fact that the majority of our 6km long prospective trend is yet to be drilled, Ballywire’s exploration upside continues to ramp up. With a robust treasury and our most ambitious drilling campaign to date – four rigs turning in Ireland – we are poised to continue unlocking Ballywire’s full potential over the coming months.’

Ballywire Drill Update

The Ballywire prospect at the Company’s 100%-owned PG West Project in Republic of Ireland, represents the most significant mineral discovery in Ireland in over a decade. First announced in Sept-2022, the discovery has 64 holes drilled and reported by Group Eleven to date, including the most recent two holes (25-3552-45 and -47) reported today (see Exhibits 1 to 6).

Assays from today’s drill holes are summarized above and below (and in Exhibits 4 and 5). Mineralization consists predominantly of sphalerite, galena and pyrite, with the Cu-Ag bearing zones also containing chalcopyrite and suspected tennantite-tetrahedrite.

In addition to results from 25-3552-47, described above, hole 25-3552-45 intersected two zones of significant mineralization along a fault structure (see Exhibits 3 and 5). Strong exploration upside remains further to the NNW and SSE along this section.

Exhibit 4. Summary of Assays from 25-3552-47 at Ballywire

Note: True thickness of the mineralized intervals in hole 25-3552-47 as a percentage of the down-hole interval, is estimated to be approx. 90-100% for Waulsortian-hosted zones, and 60-80% for sub-Waulsortian zones; ‘-‘ means less than 0.01% (<100 ppm).

Exhibit 5. Summary of Assays from 25-3552-45 at Ballywire

Note: True thickness of the mineralized intervals in hole 25-3552-45 as a percentage of the down-hole interval, is estimated to be approx. 80-100%.

Drilling at Ballywire continues with three rigs. Currently, thirteen (13) new holes are completed or near completed (and in the process of being logged, sampled and assayed). These are shown in Exhibit 2, including: (i) four holes collared approx. 200m E of G11-3552-08; (ii) two holes testing approx. 780m SE of G11-3552-08; (iii) six holes drilled along a drill fence hosting G11-468-01; and (iv) one hole testing approx. 80m SW of G11-3552-12. Note, one additional rig is active at the Company’s Stonepark Project.

The Eastern Expansion Drill Program Identified Several Mineralized Northwest Structures Hosting Shallow Mineralization Encountered Within a 1.2 Kilometre Trend

EASTERN EXPANSION PROGRAM HIGHLIGHTS:

• At least three mineralized northwest oriented structures have been identified within the 1.2 kilometre eastern expansion trend running parallel to the Pittsburg-Monarch fault that suggest a series of footwall fault splays as opposed to a singular east-west structure;
• TXC25-173 cut 0.92 metres of 2,122.7 grams per tonne (g/t) silver equivalent (AgEq) (1,162 g/t silver (Ag) & 8.79 g/t gold (Au)) from 220.9 metres, and a separate zone of 1.04 metres grading 534.8 g/t AgEq (189.8 g/t Ag & 3.16 g/t Au) from 215.5 metres;
• TXC25-178 drilled 6.4 metres of 296.6 g/t AgEq (135.7 g/t Ag & 1.47 g/t Au), including 0.46 metres of 3,853 g/t AgEq (1,771 g/t Ag & 19.06 g/t Au) from 183.8 metres in a north-south oriented structure within the M&I Conversion Area at DPB South; and

Blackrock Silver Corp. (TSXV: BRC,OTC:BKRRF) (OTCQX: BKRRF) (FSE: AHZ0) (‘Blackrock’ or the ‘Company’) announces the final results from its fully-funded eastern expansion drill program (the ‘Eastern Expansion Program’ or the ‘Program’) at its 100% owned Tonopah West project located in Nye and Esmeralda Counties, Nevada, United States (‘Tonopah West’).

The Eastern Expansion Program was a follow up to the Company’s successful Scout drilling program completed at Tonopah West in February 2025 (see March 31, 2025 news) which shows additional upside for the shallow southern portion of the Denver-Paymaster and Bermuda-Merten vein groups (‘DPB South‘) resource area (the ‘M&I Conversion Area‘) to expand the resource area 1,200 metres in an easterly direction (the ‘Eastern Expansion Zone‘).

The Company commenced the Eastern Expansion Program in July 2025 within the Eastern Expansion Zone, utilizing reverse circulation (RC) drilling with RC pre-collars to establish initial holes, which were then deepened using diamond core drilling (core tails) for more detailed geological analysis. The Program drilled a total of 6,798 metres (22,896 feet) in twenty-four drillholes, however, only 22 drillholes were completed, as two pre-collar holes were not usable for core tails. Of the 22 completed drillholes, three were core holes completed from surface.

Andrew Pollard, Blackrock’s President and CEO, stated, ‘Whereas we set out to target a single east-west mineralized structure, drilling from our Eastern Expansion Program has defined at least three distinct, parallel mineralized zones oriented northwest. These structures appear to be splays off the Pittsburgh-Monarch fault system. Each of these zones has intersected shallow, high-grade, and thick mineralization, indicating significant potential for further expansion in the area. Additionally, drilling in the M&I Conversion Area at DPB South has successfully connected previously isolated intercepts, confirming the presence of north-south trending structures and suggesting additional tonnage potential. Work on our upcoming mineral resource estimate and preliminary economic assessment is now underway and on track for a targeted completion date in February 2026. These will incorporate data from both our Northwest and Eastern Expansion drill programs.’

Table 1 summarizes the final results of the Eastern Expansion Program using a cut-off grade of 150 g/t AgEq.

Table 1: Eastern Expansion Drill Program Significant Results Using a 150 g/t AgEq Cut-off Grade

The Eastern Expansion Program encountered at least three northwest oriented structures which appear to be mineralized and offset the southern caldera margin to the northeast. The structures are parallel to the Pittsburg-Monarch fault and suggest a series of footwall fault splays associated with the main Pittsburg-Monarch fault. Figure 1 below shows the approximate location and orientation of the northwest fault system.

Drilling to date shows shallow, high-grade, and thick zones of mineralization in each of these structures and suggest increased expansion potential along this northwest structural corridor. Historically, the Pittsburg-Monarch fault was considered an ore control within the district with the thickest historically mined veins at Victor and Ohio abutting the main fault. The Company’s drilling in the Eastern Expansion Zone has returned thick vein intervals of gold and silver along the parallel structures confirming the importance of the Pittsburg-Monarch and its footwall fault splays.

Two drillholes, TXC25-171 and TXC25-178, were drilled in the M&I Conversion Area. These drillholes were directed to the west to understand several north-south structures encountered in the previous drilling. The Program was successful in capturing high-grade drill intervals from the north-south structures and shows there are multiple mineralized structures with similar orientation in the area.

Although below the cut-off grade of 150 g/t AgEq, drillholes TXC25-167, -168, -175, -176, -177 and TXC25-179 were mineralized with silver equivalent values ranging between 31 and 133 g/t AgEq. Table 2 shows the range of gold and silver values encountered along the northwest oriented structures.

Quality Assurance/ Quality Control

All sampling is conducted under the supervision of the Company’s project geologists, and a strict chain of custody from the project to the sample preparation facility is implemented and monitored. The RC samples are hauled from the project site to a secure and fenced facility in Tonopah, Nevada, where they are loaded on to American Assay Laboratory’s (AAL) flat-bed truck and delivered to AAL’s facility in Sparks, Nevada. A sample submittal sheet is delivered to AAL personnel who organize and process the sample intervals pursuant to the Company’s instructions.

The RC samples are lined out at the lab and logged into AAL’s system. The samples are dried, crushed to 85% passing 10 mesh (2mm) and a 250-gram sub-sample split is collected and pulverized to 200 mesh (74 micron) in a ring and puck pulverizer. Then the pulverized material is digested and analyzed for gold using fire assay fusion and an Induced Coupled Plasma (ICP) finish on a 30-gram assay split (FA-PB30-ICP). Silver is determined using five-acid digestion and ICP analysis (ICP-5AM48). Over limits for gold and silver are determined using a gravimetric finish (GRAVAU30 and GRAVAG30). Data verification of the assay and analytical results are completed to ensure accurate and verifiable results. Blackrock personnel insert a blind prep blank, lab blank or a certified reference material approximately every 15th to 20th sample.

Mineralization intersected in 8 of 9 holes at Tahami South, directly adjacent to Aris Mining’s producing operations in the Segovia gold district

Quimbaya Gold Inc. (CSE: QIM,OTC:QIMGF) (OTCQB: QIMGF) (FSE: K05) (‘Quimbaya’ or the ‘Company’) is pleased to announce the discovery of two new mineralized vein systems at its 100%-owned Tahami South Project in the Segovia-Remedios gold district of Antioquia, Colombia.

The Company’s ongoing drill program at Tahami South has successfully identified vein systems that include the previously targeted Vein S and Vein V, confirming the presence of mineralization consistent with quartz vein systems mined regionally. These results confirm the continuation of the Segovia district’s geological architecture onto Quimbaya’s ground, a core thesis of the Company’s strategy.

‘This is a milestone event for Quimbaya. These first vein discoveries validate our thesis and represent a turning point as we move from land assembly into value creation through the drill bit,’ said Alexandre P. Boivin, CEO of Quimbaya Gold. ‘They are not just promising results, they are proof that we’re on to a significant mineralized system, with the grades, geometry, and geology that define Colombia’s most productive gold district.’

Discovery Highlights

• Several Veins intersected across multiple drill platforms

• Mineralization intersected in 8 out of 9 drill holes, demonstrating strong structural continuity and robust targeting accuracy in the inaugural Phase 1 program.

• Drilling remains ongoing, with over 4,000 meters completed to date; the program has been extended beyond its initial scope in response to encouraging early results.

• Two distinct vein structures system (S & V) discovered, confirming Segovia-style mineral continuity on Quimbaya’s ground.

• Mineralization comprises quartz, barite, carbonate veining with sulphide assemblage (pyrite, chalcopyrite, galena, sphalerite).

‘These intercepts confirm that we are tapping into the same geological architecture that has made the Segovia district one of the most prolific gold producers in Latin America,’ said Ricardo Sierra, B.Sc., AusIMM, VP Exploration. ‘We see clear continuity in structure, mineralogy, grade, and believe we are only beginning to uncover the full potential at Tahami South.’

While initial assay results have been received from select drill holes, the Company is continuing to await the return of a significant portion of its Phase 1 drill campaign. In the interest of providing a more complete and technically coherent picture of the emerging discovery at Tahami South, Quimbaya intends to release assay data once a critical mass of results has been compiled. This approach ensures a balanced and contextualized interpretation of both grade distribution and structural continuity, and reflects the Company’s commitment to disciplined, data-driven disclosure as the scale of the system comes into focus.

Strategic Implications: Thesis Confirmed

The discovery of vein systems that include the previously targeted Veins S and V represents the first clear technical validation of Quimbaya’s exploration thesis: that district-scale mineralized structures extend beyond known mines into underexplored ground. The Company’s focused land acquisition strategy prioritized claims with gold & silver+ at surface and proximity to producers, and now, early drilling confirms this model is working.

With over 4,000 meters already drilled, surpassing the originally planned Phase 1 total, the Company has extended its current program to follow up on promising early results and to further evaluate vein continuity at depth and along strike. The strong correlation between drill intercepts and the geological model has reinforced Quimbaya’s exploration thesis. These results not only validate the presence of a robust mineralized system but also provide clear vectors for systematic expansion drilling in 2026.
