Nevada Organic Phosphate Reports 10.73% P₂O₅ Over 4.50 Metres in Drill Hole MM26-9 at Murdock Mountain, Nevada

MM26-9 Assay Results: Detailed Grades and Intervals in Upper Phosphate Zone

Drill hole MM26-9, positioned at UTM coordinates 723798E, 4568545N (NAD 83), was completed as a vertical hole to 146.93 metres (481.93 feet). The Upper Phosphate Zone was intersected between 96.00 and 100.50 metres downhole, yielding a weighted average grade of 10.73% P₂O₅ over an apparent thickness of 4.50 metres. With core angles recorded between 80 and 90 degrees, the true thickness is 4.48 metres (14.70 feet), nearly identical to the apparent thickness.

Individual sample assays ranged from 5.28% P₂O₅ over 1.00 metre (sample 1121685, 96.00–97.00 m) to a peak of 15.10% P₂O₅ over 1.45 metres (sample 1121687, 98.00–99.45 m). Another 1.05-metre sample (1121688, 99.45–100.50 m) returned 10.65% P₂O₅. These four consecutive samples form the reported Upper Phosphate Zone intersection. Additionally, sample 1121719, collected between 126.00 and 127.00 metres, returned 8.18% P₂O₅ over 1.00 metre and is attributed to the Lower Phosphate Zone.

Comparison to Previously Reported Hole MM25-6 at Same Target

MM26-9 results can be compared with hole MM25-6, drilled last fall at coordinates 723833.01E, 4568432.71N, approximately 100 metres south and downslope from MM26-9. MM25-6 reported 4.58 metres of 11.89% P₂O₅ in the Upper Phosphate Zone, slightly higher than MM26-9's 10.73% over 4.50 metres. MM25-6 also yielded an unexpectedly high Lower Phosphate Zone interval of 17.47% P₂O₅ over 4.11 metres, which MM26-9 did not replicate, instead showing a typical Lower Phosphate Zone intersection of 8.18% over 1.00 metre.

The release also mentions drill hole MM26-8, which returned a poor result interpreted as a "local, small-scale anomaly." Although assay details for MM26-8 were not disclosed, the company’s technical commentary suggests this result does not represent broader mineralisation at the target horizon. Together, data from MM25-6 and MM26-9 support continuity in the Upper Phosphate Zone across the tested area.

Stratigraphic Framework: Meade Peak Member and Upper Phosphatic Zone

Nevada Organic Phosphate’s exploration targets the Upper Phosphatic Zone, a stratigraphic interval within the Meade Peak Member. According to the release, the Meade Peak Member typically consists of 28 to 40 metres (92 to 131 feet) of phosphatic siltstone and phosphorite. The Upper Phosphatic Zone is described as a 3.4 to 7.6 metre (11 to 25 feet) interval within this sequence, based on William Fedewa’s 1980 M.Sc. thesis derived from trench observations.

In MM26-9, the qualified person noted a strong Meade Peak intersection of 42.15 metres, with the Upper Phosphate Zone described as "consistent and well-developed." The 4.50-metre thickness of the Upper Phosphate Zone in MM26-9 falls within the 3.4 to 7.6 metre target range, and the 10.73% P₂O₅ grade is broadly comparable to the 11.89% from MM25-6. The company expects thickness variations to be further confirmed by laboratory assays as drilling progresses.

Management Insights on Mineralisation Continuity

Robin Dow, CEO of Nevada Organic Phosphate, stated: "MM26-9 provides another solid intersection and continues to support the continuity we're working to confirm across the broader target area. With MM26-10 testing a 1.5-kilometre strike extension, we're excited to advance this program and add the information needed to support our upcoming decisions." The release does not specify the nature of these forthcoming decisions.

Garry Smith, P.Geo and Director, added: "MM26-9 intersected a strong 42.15 metres of Meade Peak, including a consistent and well-developed interval of the Upper Phosphate Zone. This reinforces the continuity we are working to define across the trend. In that context, we view the poor result from MM26-8 as a local, small-scale anomaly. Each hole adds valuable information, and the overall dataset continues to support our technical understanding of the target horizon." These remarks reflect the company’s technical interpretation and should be considered alongside the full dataset, including the more limited Lower Phosphate Zone result from MM26-9 compared to MM25-6.

Drill Hole MM26-10: Evaluating a 1.5-Kilometre Strike Extension Southwest

The announcement notes that MM26-10 was "almost completed" at the time of release, drilled from Pad 12 approximately 1.5 kilometres southwest of MM26-9. This site is described as a new area not previously drilled. No assay results for MM26-10 were included, with laboratory results to be released once received and validated.

The significance of MM26-10 lies in its potential to expand the project’s scale. Confirming the Upper Phosphate Zone 1.5 kilometres away from the current cluster would materially enlarge the mineralisation footprint. However, these exploration results remain pending; no assay data for MM26-10 is available yet, and investors should consider the outcome unconfirmed until formally disclosed.

Murdock Mountain Property and Project Scale

The Murdock Mountain Property is located in Elko County, northeastern Nevada, an area with established mining infrastructure. Nevada Organic Phosphate describes the phosphate bed as roughly 6.6 kilometres long, with potential strike extensions exceeding 30 kilometres. The company states this is the only known large-scale organic sedimentary phosphate project in North America.

The property is near the main highway to Montello and Elko, Nevada, and close to rail connections to California and the East Coast. The release does not include resource estimates, economic studies, or production timelines, as the project remains in exploration. Capital and operating costs were not disclosed.

Analytical Procedures: XRF Whole-Rock Fusion and ISO-Accredited Laboratory Standards

All sample preparation and analysis for MM26-9 were performed by ALS Laboratories, an independent commercial lab accredited to ISO/IEC 17025:2017 for mineral analysis. ALS undergoes regular audits by the Standards Council of Canada (SCC) and the Canadian Association for Laboratory Accreditation (CALA). Phosphate (P₂O₅) assays used the ME-XRF24 whole-rock fusion method, where samples are fused with lithium borate and analyzed by X-ray fluorescence (XRF). This technique provides high-precision measurements of major oxides including phosphorus, calcium, and silica.

ALS maintains strict internal QA/QC protocols, inserting certified reference materials, blanks, and duplicates in each batch. These procedures comply with NI 43-101 reporting standards. Utilizing an ISO-accredited third-party laboratory ensures data reliability and supports the credibility of reported assay results.

QA/QC Program: Blanks, Certified Reference Materials, and NI 43-101 Compliance

In addition to ALS’s controls, Nevada Organic Phosphate implements its own QA/QC program aligned with NI 43-101 standards. The company inserts a generic sand blank approximately every 11 samples (about 9.3% of the sample stream) to monitor contamination during preparation and analysis. Certified reference materials (CRMs) are inserted roughly every 22 samples (approximately 4.5%), typically two per drill hole.

Analytical accuracy was verified against BAM 826-1, a certified phosphate slag reference material from Germany’s Federal Institute for Materials Research and Testing (BAM). The acceptance criterion requires CRM results to fall within certified values plus or minus three standard deviations, consistent with mineral exploration industry standards. The company is confident that QA/QC outcomes validate assay data reliability and phosphate grade integrity.

Qualified Person Approval and NI 43-101 Technical Disclosure

Technical information in the release, including assay results and detailed core logging, was approved by Kenneth N. Tullar, AIPG Certified Professional Geologist (CPG 11142), serving as the independent qualified person for the drill program. Mr. Tullar reviewed and endorsed the technical content, fulfilling NI 43-101 qualified person requirements for Canadian public companies reporting mineral exploration results.

The involvement of an independent qualified person, rather than a company-affiliated geologist, adds an extra layer of technical oversight. Investors are advised to consider the full technical context of exploration-stage disclosures, including distinctions between intersection widths, true thicknesses, and the preliminary nature of drill results before any resource estimation.

Market Reaction and Share Price Context Post MM26-9 Announcement

Nevada Organic Phosphate trades on the Canadian Securities Exchange under the ticker NOP and on OTCQB as NOPFF. Immediate share price impact was unclear from public information at the time of writing. As a junior exploration company, share prices can be sensitive to drill results, project news, and commodity market trends.

Phosphate is a vital input for agricultural fertilizers and has gained attention amid food security and energy transition concerns emphasizing domestic critical mineral supply chains. Nevada Organic Phosphate’s claim of hosting the only known large-scale organic sedimentary phosphate project in North America may influence investor perception, though no independent verification was provided. The project remains exploratory, and investors should evaluate disclosures accordingly.
