Warren District Project

Sidney Resources Corporation is advancing one of Idaho’s most historically significant mining areas: the Warren Mining District, located north of McCall. Encompassing over 3,800 acres of mineral-rich terrain—including the Silver Monarch Mine, Unity Mining properties, and the Little Giant Vein—this site is the centerpiece of Sidney’s operational and development strategy.

The Warren District has a rich legacy dating back to the 1860s. However, early processing methods failed to recover many valuable elements, with over 37% of the ore categorized as “insoluble.” Today, modern metallurgical advances have revealed these tailings to be rich in platinum group metals (PGMs), rare earth elements (REEs), and refractory gold.

According to geologist Richard Morris, Sidney controls over 22 high-grade veins, including:

• 3+ million tons of ore at Little Giant Vein
• Estimated 2.86M oz of gold and 11.5M oz of silver
• Current market value: Over $8.7 billion

Assays from PTOE Labs, Auris Noble, and Florin Analytical confirm high concentrations of:

• Gold: up to 431.5 g/t
• Platinum: 329.17 g/t
• Iridium: 186.62 g/t
• Rhodium, Osmium, Ruthenium, and multiple REEs

Sidney is building a 1.75-mile access road with environmental benefits, replacing a hazardous riparian route. The new path eliminates culverts and stream crossings while reducing sediment runoff—supporting both tribal and federal conservation goals.

The Warren District also serves as Sidney’s operational hub, complete with:

• A test mill upgraded with jaw crushers, ball mills, and shaker tables
• On-site concentrate stockpiles
• 500+ lbs of concentrates and 40+ tons of #3-grade material ready for refining
• Estimated 45,000+ oz of gold recoverable from existing stockpiles alone

Sidney has established a metallurgical lab in Gem County, Idaho, equipped with:

• A high-temperature PGM furnace
• Advanced air filtration systems
• A new separation table for fine metal recovery

These facilities support extraction of complex alloys and refractory ores that traditional mills cannot handle—essential for full-scale commercialization.

With PGMs and REEs critical to clean energy, national defense, and tech industries, Sidney is positioned as a key player in securing strategic domestic supply chains. Continued testing and partnerships with experts like Dr. Jerry DeMenna, Guy Saco, and Andrew Prelea drive Sidney’s proprietary recovery methodologies.

“Our research confirms exceptional metal grades in the Warren District,” says Dr. DeMenna. “This is a unique, high-value deposit with global significance.”

Sidney avoids costly drill programs by leveraging:

• Historical maps and production data
• Bulk sampling and trenching
• Drift work and surface assays

This disciplined strategy enhances ROI while expanding resource confidence.

The Sidney Resources Corp Mine Group of claims cover a gold prospect located in the Warren Mining District, approximately 110 miles north of Boise,Idaho. TheWarren District produced over$15,000,000 of placer gold and $2,000,000 of lode gold between the period from 1869 to 1935. The Sidney Resources Corp Mine was one of some forty gold bearing fissure veins worked in the Warren Camp and lies 5,000 feet due west of the Unity Mine, the major producer in this camp.The mine was developed by a portal level which is presently inaccessible.The Little Giant can be traced along strike by the surface expression of caved stopes, dumps, pits, and float for a distance of 1,200 feet and is known to have a vertical extent at least 200 feet.The mine was reported to be in ore when mining operations were stopped in 1915. Sampling of vein material in the trenches and portal dump gave assay values ranging from 0.2 to 10.4 ounces per ton silver and 0.1 to 13.05 ounces per ton gold.
