Vancouver, British Columbia--(Newsfile Corp. - February 10, 2026) - Nevada Organic Phosphate Inc. (CSE: NOP) (OTCQB: NOPFF) ("NOP" or the "Company"), a B.C. based leader in organic sedimentary phosphate exploration, is pleased to announce continued progress in the interpretation of assay results from the first six drill holes within the Upper Phosphatic Zone ("UPZ") at Murdock Mountain. The weighted average grade of 10.93% P₂O₅ is now supported by a growing body of geochemical evidence showing that the material is not simply a phosphate ore, but a naturally balanced, multi-nutrient mineral fertilizer and soil conditioner aligned with the needs of organic and regenerative agriculture.

Ongoing analysis indicates meaningful concentrations of calcium, magnesium, potassium, iron, manganese, silicon, and trace micronutrients, all occurring in forms compatible with organic production systems. This creates a slow-release nutrient profile that supports soil health, microbial activity, and long-term fertility, key attributes for growers seeking alternatives to synthetic fertilizers.

"These assay results continue to validate the strategic importance of Murdock Mountain," said CEO Robin Dow. "We are defining a uniquely clean and naturally balanced phosphate system at a time when growers, distributors, and regulators are all demanding lower-risk nutrient sources. The chemistry we are seeing, with low impurities, meaningful co-nutrients, and slow-release phosphorus, aligns directly with the needs of organic and regenerative agriculture."

Clean Chemistry: Ultra-Low Contaminants and Regulatory Strength

The UPZ continues to demonstrate an exceptionally clean geochemical signature. Heavy metals including cadmium, arsenic, lead, and chromium occur at levels far below AAPFCO and USDA organic thresholds, and the absence of radionuclide concerns further differentiates NOP from many global sedimentary and igneous phosphate sources.

This low-impurity profile reduces certification risk for organic growers and provides a defensible regulatory advantage as global contaminant limits tighten. In a market where many phosphate products struggle with cadmium and other regulated impurities, NOP's chemistry stands out as inherently compliant and low-risk.

"As global contaminant limits tighten, clean phosphate sources are becoming increasingly scarce," said Director Garry Smith P.Geo. "NOP's low cadmium, low arsenic, and low radionuclide signature reduces regulatory friction for growers and positions the Company to compete in premium fertilizer markets where compliance and purity matter."

NOP believes its UPZ material will align directly with a Premium, Low-Risk, Multi-Benefit Input. Its combination of clean phosphorus, high natural calcium, and beneficial co-nutrients positions it as a premium, low-risk input capable of differentiating NOP from phosphate suppliers whose products often require dilution or mitigation to meet organic standards.

Naturally Occurring Co-Nutrients That Enhance Soil Health

The UPZ contains a suite of nutrients at concentrations high enough to deliver measurable agronomic benefit, strengthening NOP's positioning as a multi-nutrient, soil-health-positive phosphate.

Global Benchmarking: NOP Consistently Plots at the Clean End of Global Ranges

NOP's major oxide, heavy metal, and trace element chemistry consistently falls within, and often below, global sedimentary phosphate ranges. This includes:

• Low cadmium relative to U.S., South American, and European sedimentary deposits
• Low arsenic and lead compared to many commercial sources
• Significantly lower uranium than most sedimentary phosphates
• No red-flag elements or anomalies

These characteristics strengthen NOP's position as a strategically attractive source for premium fertilizer markets.

Incidental Liming Benefit: NOP's sedimentary phosphate contains ~29% CaO, equivalent to roughly 52% CaCO₃

While NOP does not market the product as a liming material, this naturally occurring calcium provides growers with added agronomic value by helping moderate soil acidity and improve nutrient availability. Importantly, the material contains negligible magnesium and is not dolomitic under agronomic or regulatory definitions.

This dual-benefit profile of clean phosphorus + natural calcium, further differentiates NOP from conventional phosphate sources without triggering liming material regulatory requirements.

In Summary, NOP's 11% P₂O₅ UPZ material is emerging as a clean, multi-nutrient, soil-health-positive phosphate with:

• A naturally balanced suite of macro- and micronutrients
• Ultra-low contaminants and radionuclides
• Strong alignment with organic and regenerative agriculture
• A defensible regulatory and market advantage
• A chemical profile that differentiates NOP from global phosphate suppliers

"The Upper Phosphatic Zone is demonstrating a remarkably consistent geochemical signature across the first six drill holes," added Director Garry Smith, P.Geo. "Calcium, magnesium, silicon, iron, zinc, manganese, and molybdenum all occur at agronomically relevant levels, and the impurity profile remains exceptionally low. This is not a single-nutrient ore body - it is a multi-nutrient mineral input with a clean chemistry advantage that is increasingly rare in global phosphate deposits."

NOP's "Major Oxides" assays shown above are weighted averages and believed to be representative of the Upper Phosphatic Zone (UPZ) intercepted in the first 6 drill holes. All other assays are weighted averages from UPZ intercepts from the first 3 drill holes.
