Nevada Organic Phosphate Inc. reported that heavy metal contaminant assays from the Upper Phosphatic Zone at its Murdock Mountain project returned results well below maximum allowable thresholds under AAPFCO's SUIP #25 standards. These standards are widely used by U.S. states and organic certifiers to assess fertilizer safety. Weighted-average results for key metals, including arsenic, cadmium, mercury, lead, and zinc, were materially below limits applicable to rock phosphate containing 10% P₂O₅, supporting eligibility for Organic Fertilizer Certification under USDA National Organic Program guidelines.
Management said the results validate the project's proof of concept by demonstrating consistent P₂O₅ grades and thicknesses alongside low contaminant levels. This positions the Upper Phosphatic Zone as a differentiated, organically certifiable phosphate resource with scale and continuity suitable for further resource development and expanded drilling. The company's newsroom at https://ibn.fm/NOP provides additional updates relating to the project.
The Murdock Mountain project features an organic sedimentary raw rock phosphate bed measuring 6.6 kilometres long in northeast Nevada, with additional applications extending the potential strike of rock phosphate to over 30 kilometres. This is believed to be the only known large-scale organic sedimentary phosphate project in North America. The project is situated close to the main highway to Montello/Elko, Nevada, and near the rail head to California, providing logistical advantages for potential development.
The full press release detailing these assay results is available at https://ibn.fm/Hq5VI. The announcement comes as demand for organic agricultural inputs continues to grow globally, with certified organic fertilizers representing a specialized segment of the broader fertilizer market. The ability to supply domestically sourced, organically certifiable phosphate could address supply chain concerns while meeting stringent organic certification requirements.
