Nevada Organic Phosphate reports assays from drill hole MM26-7 at Murdock Mountain

  Vancouver, British Columbia – TheNewswire - June 10, 2026 - 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 report continued strong assay results of a weighted average of 11.82% P 2 O 5 over an apparent thickness of 6.0 metres from drill hole MM26-7, recently completed on its wholly owned Murdock Mountain Property in Elko County, Nevada.   CEO Robin Dow stated: “MM26‑7 has returned another solid P ₂ O ₅ assay, adding to the growing body of evidence that our exploration target is both laterally consistent and technically compelling. Each new data point contributes to the de‑risking of the project and strengthens our foundation for the next phase of work.”   Garry Smith, P.Geo and director added: “The assays from MM26‑7 provides another consistent data point within the phosphate‑bearing horizon and supports the continuity we are observing across our drill program. Each result contributes to refining our geological model and helps guide the next steps of the program in a measured, technically defensible manner.”   The Company’s exploration target is the Upper Phosphatic Zone, a 3.4 to 7.6 metre (11 to 25 feet) interval within the Meade Peak Member, which itself comprises 28 to 40 metres (92 to 131 feet) of phosphatic siltstone and phosphorite.

This stratigraphic framework is based on the work of William Fedewa (M.Sc. thesis, 1980) from trench observations. Variations in the thickness of the Upper Phosphatic Zone encountered during the current drill program will be confirmed through laboratory assays.   Drill Hole MM26-7     Drill hole MM26-7, located at 724384E, 4569078N, was drilled vertically to a depth of 152 metres (498.6 feet). The drill collar is positioned approximately 100 metres north and upslope from last fall’s drill hole MM25-1, which intersected 38 metres of the target Meade Peak stratigraphy. MM26-7 intersected an apparent 39 metres (127.9 feet) of the same Meade Peak interval.    Drill Assay Results for Upper Phosphatic Zone   MM26-7 assays returned a weighted average of 11.82% P 2 O 5 over an apparent thickness of 6.0 metres (19.68 feet).   MM25-1, previously reported , intersected a weighted average of 10.23% P 2 O 5 over an apparent thickness of 5.12 metres (16.79 feet).   Collar Location Coordinates (WGS 84)     MM26-7 Upper Phosphatic Zone  P 2 O 5 Assays     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.
