Nevada Organic Phosphate Announces Continued Excellent Low Heavy Metal Assays for Drill Hole MM26-10 at Murdock Mountain and Promotional Activity Engagement

VANCOUVER, BC, Aug. 31, 2026 /CNW/ -- Nevada Organic Phosphate Inc. ("NOP" or the "Company") (CSE: NOP) (OTCQB: NOPFF), a B.C. based leader in organic sedimentary phosphate exploration, is pleased to announce that the heavy metal contaminant assays from the Upper Phosphatic Zone in drill hole MM26-10 at Murdock Mountain, continue to demonstrate results well below the maximum allowed limits for Organic Fertilizer Certification. MM26‑10, a 1.5‑kilometre step‑out along strike at the Murdock Mountain project, returned another excellent intersection of 10.89% P₂O₅ over 3.60 metres. (See previous News Release dated August 26, 2026)

In the chart below, please note the SUIP #25 and the California values. NOP's Upper Phosphate Zone values are significantly lower than the maximum heavy metal values allowed.

Robin Dow, CEO, stated: "This is another solid intersection from MM26‑10 demonstrating that the Upper Phosphatic Zone continues to deliver predictable, clean, very low heavy metals content criteria suitable for Organic Certification. We continue to meet our objectives, positioning NOP as a genuinely differentiated entrant in the fertilizer market."

In the United States, organic certification is governed by the USDA National Organic Program (USDA-NOP). The USDA-NOP does not publish its own numeric heavy-metal limits for mineral fertilizers like rock phosphate. Instead, certifiers rely on two things:

1. USDA-NOP 205.203(c) soil and plant amendments must not contaminate soil or crops with heavy metals. 
   
   
2. State fertilizer laws can vary, but almost universally adopt AAPFCO's SUIP #25 Heavy Metal Rule for determining whether a fertilizer is adulterated (AAPFCO, Association of American Plant Food Control Officials, created SUIP #25 to give states a consistent, science-based method for regulating heavy metals in fertilizers. It is not a law, but most states adopt it into their fertilizer programs).

USDA Organic Certification: For organic production, a rock phosphate fertilizer must:

• Be mined, not chemically processed
• Not contain synthetic additives
• Not exceed heavy-metal levels that would contaminate soil or crops
• Typically meet SUIP #25 limits (this is what certifiers check)

If a product meets these limits, it is generally acceptable for organic certification.

SUIP #25 sets limits per 1% P₂O₅. For fertilizer with 10% P₂O₅, multiply limit by 10.

Metal	Limit per 1% P2O5	Limit per 10% P2O5
Arsenic (As)	13	130
Cadmium (Cd)	10	100
Cobalt (Co)	136	1,360
Lead (Pb)	61	610
Mercury (Hg)	1	10
Molybdenum (Mo)	42	420
Nickel (Ni)	250	2,500
Selenium (Se)	26	260
Zinc (Zn)	420	4,200
	Note: all values in ppm

These are the maximum allowable concentrations before a phosphate fertilizer is considered adulterated under U.S. state fertilizer laws.

Lab Assaying Methods & QA/QC

All sample preparation and analytical work was carried out by ALS Laboratories ("ALS"), an independent commercial laboratory accredited to ISO/IEC 17025:2017 for mineral analysis. Samples were delivered to the ALS Geochemistry in Elko, Nevada preparation facility and then forwarded to ALS Geochemistry in Vancouver for analysis. ALS operates under rigorous quality management systems and is regularly audited by recognized accreditation bodies, including the Standards Council of Canada (SCC) and the Canadian Association for Laboratory Accreditation (CALA).

Heavy metal assaying was by ME-MS61 trace element analysis: Samples were digested using a near-total four-acid procedure (HF; HNO₃; HClO₄; HCl) and analyzed by ICP-MS and ICP-AES. This technique delivers ultra-trace detection of a broad suite of elements, including deleterious or contaminant metals such as arsenic, cadmium, mercury, and lead, supporting environmental and processing assessments.

ALS maintains strict internal QA/QC protocols, including the insertion of certified reference materials, blanks, and duplicates with each batch of samples. These measures ensure that analytical results meet internationally recognized standards of accuracy and reliability, consistent with the requirements of NI 43-101 reporting.

Company Quality Assurance / Quality Control (QA/QC)

The Company implemented a rigorous QA/QC protocol consistent with NI 43-101 standards, including the insertion of blanks and certified reference materials into the sample stream.

Blanks: The Company regularly inserted a blank comprised of generically sourced sand every 11 samples (or 9.3%) to monitor potential contamination during sample preparation and analysis.

Certified reference materials ("CRM"): CRMs used in mineral exploration are used to assess analytical accuracy and are usually rock powders comprised of known concentrations of the metal(s) of interest. CRMs are usually obtained from commercial suppliers who provide the average of many analyses of the CRMs by multiple labs, which is referred to as the certified value, and a standard deviation of the analyses from which the certified value is determined. A typical criterion for accepting the analyses of CRMs in the mineral industry is that they should fall within a range determined by the certified (or "target") value ± three standard deviations ("3 STD"). Analytical accuracy was verified against BAM 826-1, a certified reference material for phosphate slags issued by Germany's Federal Institute for Materials Research and Testing (BAM). The Company inserted BAM 826-1 CRM standards every 22 samples (or 4.5%), or about 2 per drill hole.

The Company is satisfied that the QA/QC results demonstrate the reliability of the assay data and support the integrity of the phosphate grades reported herein.
