Group Eleven Resources Corp. (TSXV: ZNG,OTC:GRLVF) (OTCQB: GRLVF) (FSE: 3GE) (‘Group Eleven’ or the ‘Company’) is pleased to announce the latest three step-out drill holes from the discovery horizon at its Ballywire discovery (‘Ballywire’) at the 100%-owned PG West Project (‘PG West’), Republic of Ireland. Drilling at Ballywire’s deeper, Cu-Ag target (100-200m below discovery horizon) is in progress (to be reported as soon as possible).

Highlights:

• 25-3552-37 (90m step-out NE of 25-3552-35, hosting widest intercept to date; announced 02-Jul-25) intersected intermittent mineralization over a 185m-long interval, including:

  • Cu-Ag Intercept (hosted in Ballysteen Limestone, beneath Waulsortian Limestone)

    • 6.2m of 312 g/t Ag and 0.95% Cu (starting from 303.9m downhole), including

    • 2.8m of 549 g/t Ag and 1.77% Cu, including

    • 0.3m (30cm) of 2,470 g/t Ag and 5.87% Cu

  • Zn-Pb-Ag Intercepts (hosted within Waulsortian Limestone)

    • 4.9m of 5.2% Zn+Pb (4.0% Zn and 1.2% Pb), 45 g/t Ag (starting from 125.9m), including

    • 0.1m (14cm) of 65.1% Zn+Pb (46.4% Zn and 18.7% Pb), 654 g/t Ag

• 25-3552-36 (90m step-out SE of the above hole), intersected intermittent mineralization over a 38m-long interval, including:

  • 2.8m of 231 g/t Ag and 0.85% Cu, including

  • 0.2m (16cm) of 3,820 g/t Ag and 12.60% Cu (among highest Ag/Cu assays in Ireland)

• 25-3552-34 (35m step-out NNW of the above hole), intersected intermittent mineralization over 16m-long interval, including 1.9m of 59 g/t Ag and 0.75% Cu

• These results extend the strike length of Ballywire’s main discovery corridor by 135m from 1,300m to 1,435m, while further emphasising Cu-Ag potential at depth

• This corridor is hosted within a larger 2.6km long trend of robust mineralization pierced by drilling to date at Ballywire, along a prospective trend of over 6km (defined by four regional gravity-high anomalies, only one of which has been systematically drill tested to date)

• The Company’s ‘deeper Cu-Ag’ target (100-200m below the Zn-Pb-Ag horizon) is currently being drill tested with two holes completed and a third hole in progress

• Three rigs are turning at Ballywire with approx. 5,700m of drilling completed year-to-date; Group Eleven aims to complete a further approx. 25,000m of drilling by end of 2026 (fully funded)

‘Today’s results expand our main discovery corridor by 135m and add to growing evidence suggesting a deeper Cu-Ag horizon one to two hundred metres below Ballywire’s current discovery horizon,’ stated Bart Jaworski, CEO. ‘This deeper target is currently being drilled, with two holes finished and a third started. We look forward to releasing these results as soon as assays are available. With three rigs turning each on excellent targets at Ballywire, a fourth rig likely to be added soon and a recently announced strengthened cash position now totalling C$8.4 million, Group Eleven is poised to keep generating shareholder value through the drill bit for the foreseeable future.’

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 56 holes drilled and reported by Group Eleven to date, including the most recent three holes (25-3552-34, -36 and -37) reported today (see Exhibits 1 to 4).

Today’s results add further evidence that the mineralized trend at Ballywire continues further east towards G11-3552-08. One of the Company’s three rigs is now drilling a fence of holes collared 200m east of this hole (see Exhibit 1), testing for the further continuation of the mineralized trend. A second rig is drilling a fence of holes testing for the deeper Cu-Ag target (within the Lower Limestone Shale) with two holes completed and the third recently started (see ‘-40’ in Exhibit 1, and ’25-3552-40′ in Exhibit 2). A third rig is drilling along the section of holes containing G11-468-01 and 00-468-5 (see Exhibit 1) to test for a SW continuation of high-grade mineralization. The Company plans to soon add a fourth rig at Ballywire, geared towards reconnaissance drilling further outboard of the current mineralized corridor. Meanwhile, two holes located 1.3km to the ENE (near gravity anomaly ‘D’; see Exhibit 3) were recently completed (assays pending), with follow up drilling planned upon receipt of a second drill permit (recently submitted) which would allow for more flexibility on drill locations further to the NE.

Note: Of the four gravity-high anomalies above, only the ‘C’ anomaly has been systematically drilled to date

Assays from today’s drill holes are summarized above (see Exhibit 4). Mineralization consists predominantly of sphalerite, galena and pyrite, with the Cu-Ag bearing zones also containing chalcopyrite and suspected tennantite-tetrahedrite. Substantial Cu-Ag mineralization in 25-3552-37 is located within the Ballysteen Limestone, in contrast to 25-3552-35, where a strong Cu-Ag interval occurs at the base of the Waulsortian Limestone. Varying lithologies hosting Cu-Ag mineralization suggest a dynamic and potentially robust mineralizing system with respect to copper and silver.

Exhibit 4. Summary of Assays from 25-3552-37, -36 and -34 at Ballywire

Note: True thickness of the mineralized interval in holes 25-3552-37, -36 and -34, as a percentage of the down-hole interval, is estimated to be 70-80%, 90-100% and 90-100% respectively; ‘-‘ means equal to or less than 0.01% (

Drilling at Ballywire continues with three rigs. Currently, twelve (12) new holes are completed or near completed (and in the process of being logged, sampled and assayed). Nine (9) of these are shown in Exhibit 1, with two other holes near gravity-high anomaly ‘D’ (located 1.3km to the ENE) and one hole collared approx. 200m NNW of G11-468-01 (see Exhibit 1).

Prismo to Host Webinar on September 3rd

Vancouver, British Columbia, August 27, 2025 TheNewswire – Prismo Metals Inc. (the ‘ Company ‘) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to provide an update on ongoing exploration work at the Silver King mine. The exploration work currently in progress has resulted in the identification of two previously undescribed veins with mineralogical characteristics similar to those at Silver King (Fig. 1).  Preliminary analysis with a portable XRF instrument shows the mineralization contains lead, silver, copper and zinc. A first batch of samples has been submitted to the lab, with results expected in the coming weeks.

‘During reconnaissance work, we have been working on understanding the controls of mineralization at the Silver King mine,’ stated Dr. Craig Gibson, Chief Exploration Officer of the Company. ‘Two previously undescribed veins were discovered (Figure 1.), including one at a large mine dump about 300 meters south of the Silver King mine shaft. We believe this may have been the location of significant silver production. Several veins and prospect pits occur 300 meters along strike to the NE to a point near the Silver King glory hole. Of particular note, this is the first time we have observed mineralization similar to the Silver King deposit outside of the historic mine and so it provides an exciting new exploration target.’

The green line represents a quartz vein with copper mineralization with silver values.

He added: ‘The stockpile of vein materials is located above an area that was used to smelt the sulfide ore, and numerous conical shaped pieces of slag, with the pointed tips that would have contained the concentrated metals removed. Examination of a collapsed mine portal showed the presence of quartz veinlets containing sulfide minerals, mainly sphalerite, galena and tetrahedrite.’

Initial work at the Silver King project has consisted of a property wide survey of the historic mines and prospects, as well as a geochemical and alteration mineral survey around the surface expression of the Silver King deposit and other mineral occurrences. The Silver King deposit is located a few kilometers from the Resolution Copper deposit (a joint venture between Rio Tinto and BHP) and the high-grade Magma mine, a former copper and silver producer. Mineralization at Silver King is hosted by the same rock sequence that hosts the Resolution Copper deposit, but which is exposed at the surface and is not covered by the thick sequence of volcanic rocks that covers Resolution Copper.

Prismo plans to complete the current exploration program in September and conduct a preliminary exploration drill program upon obtaining its drill permit. The Company has submitted a plan of operations for the drill program with the Forest Service. Work is ongoing to further define the controls on mineralization at the historic mine. It is also expected that access to the historic workings on the 114 level of the mine will be achieved shortly.

‘Having toured the Silver King mine site (along with the Ripsey mine) with Chief Exploration Officer Craig Gibson in early August, the prevalence and scale of the historic and current producing mines in the district was truly impressive,’ stated Gordon Aldcorn, President. ‘Acquiring a past producing mine with virtually no modern exploration in such close proximity to other world class deposits is a rare opportunity for Prismo Metals.’

On July 4, 2025, the Company announced that it had signed option agreements to acquire 100% interest in the Silver King and Ripsey mines — both historic high-grade precious and base metal mines located in Arizona’s prolific Copper Belt near its flagship Hot Breccia project.  A crew led by Dr. Craig Gibson, Chief Exploration Officer of the Company, has been working at the project since Aug 4.

About Silver King

Discovered in 1875, the Silver King mine is one of Arizona’s most important historical producers, yielding nearly 6 million ounces of silver at grades of up to 61 oz/t. Selected samples from small-scale production in the late 1990s returned historical grades as high as 644 oz/t silver (18,250 g/t) and 0.53 oz/t gold (15 g/t). Additionally, the presence of freibergite (AgCuSbS) suggests a potential for antimony, a critical mineral with growing strategic demand.

Strategic Location

The Silver King mine sits only 3 km from the main shaft of the Resolution Copper project — a joint venture between Rio Tinto and BHP and recognized as one of the world’s largest unmined copper deposits. (1) This unique land position is fully surrounded by Resolution Copper’s claim block, offering strategic upside.

The Silver King mine was discovered in 1875 and produced as much as 10,000 ounces per ton silver in near surface workings. (2) Underground production through 1889 is estimated at almost 6 million ounces of silver at grades of between 61 and 21 ounces per ton. During a second period of production from 1918 to 1928, 230,000 ounces were produced at a grade of 18.7 ounces per ton.  No significant production has occurred after 1928.

Silver King is a steeply west-dipping pipelike stockwork and breccia zone that was mined on eight levels to about 300 meters depth below a glory hole at the surface. The pipe is described as a dense stockwork with local breccia zones and a quartz core, and that due to variations in mineralogy, much of the upper portion of the body has not been mined (3) . The current owners from whom the Company has optioned the project rehabilitated the main shaft in the late 1990s, opened the upper levels of the mine and produced a small tonnage. Assay certificates from this period show selected samples with 400 to 600 ounces per ton silver with 0.2-0.5 oz/t gold and some base metals. Virtually no modern exploration has been carried out at the mine providing significant exploration upside and multiple drill targets.

With respect to the Resolution deposit, the QP has been unable to verify the information, and the information is not necessarily indicative to the mineralization on the Silver King property.
