Nevada Organic Phosphate Announces New Drilling at Murdock Mountain and Assay Results Update for MM26-8

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% P 2 O 5 over 5.00 metres true thickness."
