The economics of ADN's project is heavily dependent upon the high grade halloysite in their resource. This section of the resource has an average Al2O3 grade of 36.9% and the levels of impurities are very low ( iron oxide 0.56%, titanium dioxide 0.45%).
LRS samples achieved an average assay of 20.54% Al2O3 ( so grade is just over half of the grade ADN used in the resource underpinning the ADN's PFS ).
LRS average iron oxide content in the assays is 1.77% ( for ADN 0.56% ).
LRS average titanium dioxide content in the assays is 0.57% ( for ADN 0.45% ).
Given the grade differences and the impurities I think unlikely the material in the part of the deposit assayed by LRS can be used to achieve the same sort of pricing, let alone margins and economics as ADN.
