Nevada Organic Phosphate (CSE:NOP) says assays from recent drilling at its Murdock Mountain Project have returned ‘very low’ heavy metal concentrations that could support US organic certification of the phosphate mineralisation.
Earlier this month, the company reported an intersection of 10.89% phosphorus pentoxide (P₂O₅) over 3.6m from hole MM26-10. The 1.5km step-out extended the confirmed strike length of the Upper Phosphate zone to more than 3km.
Nevada Organic has now reported heavy metal assays from the same drill hole, with results for regulated elements including arsenic, cadmium, lead, and mercury.
According to the company, the concentrations are below maximum allowable levels used for mineral fertiliser certification in the US.
Nevada Organic notes that the US Department of Agriculture’s National Organic Program does not publish its own numerical heavy metal limits specifically for mineral fertilisers such as rock phosphate. Instead, organic certifiers commonly reference standards developed by the Association of American Plant Food Control Officials.
The company says the MM26-10 results fall within those limits, supporting the material’s potential eligibility for organic certification in the US.
“This is another solid intersection from MM26-10 demonstrating that the Upper Phosphatic zone continues to deliver predictable, clean, very low heavy metals content criteria suitable for organic certification,” CEO Robin Dow says.
Nevada Organic Phosphate is a junior exploration company with a 6.6km-long organic sedimentary raw rock phosphate bed in northeast Nevada, US.
