Vancouver, British Columbia--(Newsfile Corp. - September 21, 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 report that Falcon Drilling, our 2025 contractor, is mobilizing onto the property to complete the planned 2026 program.

As reported in the Company's news release dated August 26, 2026, the target Upper Phosphate Zone was again successfully intersected in drill hole MM26-10, extending the strike of phosphate mineralization to over 3 kilometres. New drilling will continue to move forward along the strike trend.

Robin Dow, CEO, commented: "MM26-10 intersecting the Upper Phosphate Zone was a significant milestone for NOP. That hole extended our confirmed strike length of phosphate mineralization to over 3 kilometres. Now that we have Falcon Drilling back on board, we can continue to make significant progress!"

NOP's geological model interprets the Upper Phosphate Zone as a laterally extensive, nearly flat-lying sedimentary horizon within the Meade Peak Member of the Phosphoria Formation. Continued step-out drilling is designed to test strike continuity and refine true-thickness and grade controls across the broader Murdock Mountain trend.

Garry Smith, P.Geo., Director, added: "The successful intersection of the Upper Phosphate Zone over 3 kilometres was a foundational requirement for future evaluation work. Now we can continue drilling to explore the strike potential on the Nevagro Exploration Permit." Smith added: "We have interpreted the assay data in greater detail and can now determine the Upper Phosphate Zone interval with greater clarity. The target intervals are chemically conspicuous and the reported intervals below are believed to be approximately true thickness based on core angles recorded during core logging.

We can now report that the Upper Phosphate Zone in drill hole MM26-8 was in fact intersected but was somewhat diluted by detritus. It returned 4.60% P₂O₅ over 5.00 metres true thickness."

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. 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).

Phosphate P₂O₅ assaying was by ME-XRF24 whole-rock analysis: Samples were fused with lithium borate and analyzed by X-ray fluorescence (XRF). This method provides high-precision determinations of major rock-forming oxides, including phosphorus, calcium, and silica, ensuring accurate characterization of phosphate mineralization.

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 inserts a blank comprised of generically sourced sand approximately 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 inserts BAM 826-1 CRM standards approximately 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.

Nevada Organic Phosphate Inc. (CSE: NOP) (OTCQB: NOPFF)

NOP is a junior exploration company with an organic certifiable sedimentary raw rock phosphate bed, 6.6 kilometres long, in northeast Nevada. Additional applications extend the potential strike of rock phosphate to over 30 kilometres. This is believed to be the only known large-scale organic certifiable sedimentary phosphate project in North America. It is situated close to the main highway to Montello/Elko, Nevada, and the rail head to California or the East Coast.
