” This region is of world class for porphyry systems and basic and precious metals, and we believe that there is a considerably untouched potential. Our recent fieldwork at the Silver King Mine was successful in identifying various exploration goals, apart from the historic silver mine deposit, including polymetallic veins, manto replacements and a strongly changed infringement of the stock quartess pyrite of the kartwerk. Identifying this mineralization in porphier style on the claim block is a very positive development ” said Dr. Craig Gibson Chief Exploration Officer.

The Silver King deposit is three kilometers from the resolution copper deposition and the high-quality Magma mine, a former copper and silver producer, Located 0.6 to 1.5 kilometers to the southwest Mineralization at Silver King is hosted by the same rock sequence that houses two deposits, but is exposed to the surface and is not covered by the thick order of non -defined volcanic rocks that covers the copper of the resolution. From 1911 to 1996 The Magma Mine was Developed on Veins and Replacement Deposits in the Paleozoic and Precambrian Strata and Intruiive Rocks, Producing Approximately 27.6 Million Short Tons of Ore Averaging About 4.9% COPPERTANTIES OF SALITANTS OZ) (Briggs, 2015), Possible Leading to the Discovery of the Nearby Resolution Copper Deposit (Fig. 1).
M invertering Similar to that with the magma -my is exposed in various historical mining effects with abundant oxid copper minerals, mainly malachite, what were developed along a northeastern limestone horizon near the contact with a quartz diorite infringement and quartzite along the same structural and stratigraphic trend of the Magma -my -My. The greatest appearance, with the black diamond mine in the eastern part of the claim block, was developed on a large access to abundant mirror hematite and malachite to replace a limestone bed (Fig. 2) .
In addition, an erosion -in a regional quartz -dioriet has exposed a felsic burglary to the east of the Silver King effect that was identified in historical records and now confirmed by Prismo -Geologists. This felsic infringement, earlier described as a Breccia pipe, is characterized by very strong Stockwork Kwarts-Pyriet that is gastrots changed in a quarter-rehearsal. This goal contains anomal metal values in soil samples analyzed with the XRF. According to historical reports, it has a high salt content of liquid in closures that are typical of a porphy system, which provides evidence for porphy mineralization on the Silver King -Clippel package.

“Much of the focus of the exploration program so far consisted of a property -wide overview of historical mines and prospects around the Silver King operation, ” Said Gordon Aldcorn, President of Prismo .
” The exploration work has resulted in the identification of various mineralized events on the site, including veins near the Silver King, and replacement and skarn mineralization in limestone units of the sedimentary order near the contact. ”
Part of the first exploration program consisted of a reconnaissance study of geology and mineral events, as well as a geochemic and change mineral study around the surface expression of the Silver King deposits and a second separate target in the east.
The geochemical research used a handheld XRF instrument to measure soil samples and showed discrete anomalies for CU, AG and SB around the historic glory hole, where the copper geochemistry also associated with one striking CU lower vein that was previously mentioned (fig. 3). Twenty-nine samples have been submitted to the lab, with a further fifteen samples of the Ripsey mine.
This first phase of Prismo exploration on the Silver King project already generates a better understanding of potential with new structures that have not been fully discovered in historical mining approaches. This work also helps to qualify our upcoming exercise program that is currently in the permit phase and is expected to be demanded soon.

As mentioned earlier in Primo’s press release of 28 August 2025, the commercial geologists identified two previously un described veins in the area around the historical glory hole developed on the original exposure of high-quality silver in the Silver King deposits. Visual inspection and analysis with a handheld XRF show two different veins, one with abundant silver lead and zinc and the other with copper and silver values.

About the Silver King and Ripsey Mines
The Silver King -myer was discovered in 1875 and was one of the most important historical producers of Arizona, who yielded nearly 6 million our silver in the classes up to 61 oz/t. The Silver King -my own is just 3 km from the main axis of the Resolution Copper project -a joint venture between Rio Tinto and BHP and one of the world’s largest non -minanced copper deposits with an estimated copper source of 1.787 billion tons at an average grade of 1.5% copper (1) . The unique bait position is completely surrounded by the Claim Block of Resolution Copper and offers strategic benefits. Selected samples of small -scale production In the late 1990s, the figures returned to 644 oz/t silver (18,250 g/t) and 0.53 oz/t gold (15 g/t), indicating that high -quality mineralization remains.
The Ripsey mine is a historic producer of Gold-silver copper located about 20 km west of the Hot Breccia project. Historical mining effects consisting of tunnels and shafts at different levels were developed along a vein of approximately 400 meters percussion length and 160 meters vertical. A small tonnage mineral was produced by the optor in the late 1990s. Limited sampling by Dr. Craig Gibson from the mining work has yielded 15.9 g/t gold and 275 g/t silver more than 0.75 meters and 8.7 g/t gold, 181 g/t silver, 3% copper and 9% zinc over 1 meter. With the project no modern exploration was carried out and a significant study of the exploration and multiple bordering seats offers.
