Prismo Metals Enters 2026 with Fully Funded Drill Program and New Copper Targets at the Historic Silver King

Dear Prismo Metals community,

We are pleased to report that Prismo Metals is entering the final month of 2025 in its strongest position to date. We are now fully funded to execute our Phase 1 and Phase 2 for 2,000 meter drill program at our Silver King project in Arizona, having successfully closed an upsized second tranche of our private placement.

The initial phase will target the historic Silver King mine, testing the upper half of the mineralized body and the surrounding stockwork left behind by previous miners. To begin drilling, we are awaiting the drill permit to be issued by the Forest Service, a federal entity part of the Department of Agriculture of the U.S. government.

We have recently found additional compelling exploration targets in recent weeks, including the Black Diamond copper-gold replacement target and the newly named Copper King porphyry intrusion target, both on the east side of the project.

Just this week, we announced compelling new assay results from our sampling program. We identified high-grade copper (up to 6.02% copper) at Black Diamond and, significantly, high-grade gold (up to 5.19 g/t gold) in stockwork veining at the Copper King target. These results, combined with our IP survey, which has already identified multiple resistivity and chargeability anomalies, are giving us a robust pipeline of drill targets.

For those new to Prismo Metals, let me summarize Silver King for you:

Silver King is a historic high-grade silver, copper and base metals producer:

• Discovered in 1875, became one of the most important mines in Arizona

• Produced high grade silver in two main periods: 

• 1875-89, nearly 6 million ounces of silver at average head grades of 61oz/ton to 21 oz/ton silver with significant copper, lead and zinc values

• 1918-28, produced over 230,999 oz silver with a head grade of 18.7 oz/ton

• No significant production after 1928

• No recent modern exploration

The Silver King project is uniquely positioned:

• Located near Superior, AZ and 3 km from the main Resolution Copper shaft.

• Resolution is a joint venture between BHP and Rio Tinto, which owns the largest unmined copper deposit in the world (1.5 billion tons at 1.56% Cu)

• Silver King is entirely surrounded by Resolution Copper

• Silver King is hosted by the same rock sequence that hosts the nearby Resolution copper deposit, but has the advantage to be exposed at surface and is not covered by the thick sequence of unmineralized volcanic rocks that covers Resolution

• The host rocks from the nearly Magma mine are exposed on the eastern portion of the

In 2026, we will see a major ramp up in exploration with Multiple Milestones on the Horizon:

• Obtain Silver King Drill Permit 

• Forest Service permit expected shortly 

• Select & secure the driller for drill campaign at Silver King

• Start drilling at Silver King 

• 2,000 meters in two phases

• Near the mine is the priority 

• Drill the newly discovered polymetallic vein and copper area

• Dewatering of the Silver King Mine 

• Underground exploration targeting high-grade zones

• Possible bulk sample

• Continued Exploration 

• Ripsey Mine: Detailed mapping and sampling

• Unlock value from the Hot Breccia project and drill in 2026

This drill program is supported by an exciting portfolio. Our recent success at the Ripsey Project, where we confirmed high-grade gold and silver over a 600-meter strike, remains a key value driver. Crucially, Ripsey sits on patented land, granting us the distinct advantage of not requiring federal drill permits for future work there. Meanwhile, our option extension at the Hot Breccia Project provides us with the strategic flexibility to continue partnership discussions for our permitted 5,000-meter copper drill program.

We are rapidly advancing our projects during a historic surge for our key metals. Silver has soared over 100% to $60/oz, fueled by a projected 95-million-ounce deficit, while copper hit record highs above $11,400/tonne, driven by AI and green energy demand. This simultaneous bull market is compelling major producers to urgently secure new supply. With high-grade assets in Arizona and Mexico, Prismo is strategically positioned to capitalize on these deficits and deliver North American critical minerals.

We are energized, funded, and committed to unlocking the potential of these high-grade Arizona projects. We invite you to follow our progress closely by visiting our website at www.prismometals.com and subscribing to our newsletter.

(Kitco News) - Volatility in the silver market remains elevated as prices trade near their record highs above $58 an ounce. While the precious metal has room to move higher, one market strategist is urging investors to exercise caution.

In his latest precious metals note, Mike McGlone, Senior Market Strategist at Bloomberg Intelligence, said that silver’s parabolic rally is “a little scary,” and because of the metal’s volatile nature, he sees the potential for prices to rally to $75 an ounce – or fall back to $40 an ounce.

Spot silver last traded at $58.43 an ounce, roughly unchanged on the day. However, prices are up 100% this year and are seeing their best annual gains since 1979. Silver continues to significantly outperform gold, with the gold/silver ratio trading at 72 points, a four-year low.

Although momentum indicators signal that silver is significantly overbought, many analysts have said that technical price action is playing second fiddle to market fundamentals.

Silver’s parabolic move comes as growing demand has put significant pressure on limited supplies. Five years of market deficits, driven by robust industrial demand, have significantly depleted above-ground stockpiles.

Meanwhile, the threat of potential tariffs on silver, after the U.S. government classified it as a critical metal, is adding to supply-chain turmoil and market liquidity issues. 

The final piece to silver’s recent record highs has been surging global investment demand. Analysts note that growing economic uncertainty has renewed expectations for aggressive easing from the Federal Reserve while at the same time, inflation pressures remain fairly elevated. All this is creating the perfect environment for hard assets like silver.

Although silver prices are expected to remain volatile, analysts have said there is no end in sight to the current market deficit as mine production remains constrained, and further tightness in the marketplace due to supply-chain issues should continue to support prices at elevated levels.
