Vancouver, British Columbia, August 27, 2025 TheNewswire – Prismo Metals Inc. (the ” Firm “) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is happy to supply an replace on ongoing exploration work on the Silver King mine. The exploration work presently in progress has resulted within the identification of two beforehand undescribed veins with mineralogical traits just like these at Silver King (Fig. 1). Preliminary evaluation with a conveyable XRF instrument reveals the mineralization accommodates lead, silver, copper and zinc. A primary batch of samples has been submitted to the lab, with outcomes anticipated within the coming weeks.
“Throughout reconnaissance work, now we have been engaged on understanding the controls of mineralization on the Silver King mine,” acknowledged Dr. Craig Gibson, Chief Exploration Officer of the Firm. “Two beforehand undescribed veins had been found (Determine 1.), together with one at a big mine dump about 300 meters south of the Silver King mine shaft. We consider this may occasionally have been the situation of serious silver manufacturing. A number of veins and prospect pits happen 300 meters alongside strike to the NE to some extent close to the Silver King glory gap. Of specific be aware, that is the primary time now we have noticed mineralization just like the Silver King deposit exterior of the historic mine and so it gives an thrilling new exploration goal.”

The inexperienced line represents a quartz vein with copper mineralization with silver values.
He added: “The stockpile of vein supplies is situated above an space that was used to smelt the sulfide ore, and quite a few conical formed items of slag, with the pointed ideas that might have contained the concentrated metals eliminated. Examination of a collapsed mine portal confirmed the presence of quartz veinlets containing sulfide minerals, primarily sphalerite, galena and tetrahedrite.”
Preliminary work on the Silver King challenge has consisted of a property large survey of the historic mines and prospects, in addition to a geochemical and alteration mineral survey across the floor expression of the Silver King deposit and different mineral occurrences. The Silver King deposit is situated just a few kilometers from the Decision Copper deposit (a three way partnership 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 identical rock sequence that hosts the Decision Copper deposit, however which is uncovered on the floor and isn’t coated by the thick sequence of volcanic rocks that covers Decision Copper.
Prismo plans to finish the present exploration program in September and conduct a preliminary exploration drill program upon acquiring its drill allow. The Firm has submitted a plan of operations for the drill program with the Forest Service. Work is ongoing to additional outline the controls on mineralization on the historic mine. Additionally it is anticipated that entry to the historic workings on the 114 degree of the mine might be achieved shortly.
“Having toured the Silver King mine website (together with the Ripsey mine) with Chief Exploration Officer Craig Gibson in early August, the prevalence and scale of the historic and present producing mines within the district was really spectacular,” acknowledged Gordon Aldcorn, President. “Buying a previous producing mine with just about no fashionable exploration in such shut proximity to different world class deposits is a uncommon alternative for Prismo Metals.”
On July 4, 2025, the Firm introduced that it had signed possibility agreements to accumulate 100% curiosity within the Silver King and Ripsey mines — each historic high-grade treasured and base metallic mines situated in Arizona’s prolific Copper Belt close to its flagship Scorching Breccia challenge. A crew led by Dr. Craig Gibson, Chief Exploration Officer of the Firm, has been working on the challenge since Aug 4.

About Silver King
Found in 1875, the Silver King mine is certainly one of Arizona’s most necessary historic producers, yielding practically 6 million ounces of silver at grades of as much as 61 ozt. Chosen samples from small-scale manufacturing within the late Nineteen Nineties returned historic grades as excessive as 644 ozt silver (18,250 g/t) and 0.53 ozt gold (15 g/t). Moreover, the presence of freibergite (AgCuSbS) suggests a possible for antimony, a crucial mineral with rising strategic demand.
Strategic Location
The Silver King mine sits solely 3 km from the primary shaft of the Decision Copper challenge — a three way partnership between Rio Tinto and BHP and acknowledged as one of many world’s largest unmined copper deposits. (1) This distinctive land place is totally surrounded by Decision Copper’s declare block, providing strategic upside.
The Silver King mine was found in 1875 and produced as a lot as 10,000 ounces per ton silver in close to floor workings. (2) Underground manufacturing by 1889 is estimated at nearly 6 million ounces of silver at grades of between 61 and 21 ounces per ton. Throughout a second interval of manufacturing from 1918 to 1928, 230,000 ounces had been produced at a grade of 18.7 ounces per ton. No vital manufacturing has occurred after 1928.
Silver King is a steeply west-dipping pipelike stockwork and breccia zone that was mined on eight ranges to about 300 meters depth beneath a glory gap on the floor. The pipe is described as a dense stockwork with native breccia zones and a quartz core, and that because of variations in mineralogy, a lot of the higher portion of the physique has not been mined (3) . The present homeowners from whom the Firm has optioned the challenge rehabilitated the primary shaft within the late Nineteen Nineties, opened the higher ranges of the mine and produced a small tonnage. Assay certificates from this era present chosen samples with 400 to 600 ounces per ton silver with 0.2-0.5 ozt gold and a few base metals. Just about no fashionable exploration has been carried out on the mine offering vital exploration upside and a number of drill targets.
With respect to the Decision deposit, the QP has been unable to confirm the knowledge, and the knowledge shouldn’t be essentially indicative to the mineralization on the Silver King property.
