Data Verification
Denison engages with independent consultants for estimation of mineral resources on its mineral properties, in accordance with CIM Standards and NI 43-101, as well as other studies, including the 2018 PFS and ISR field testing and engineering studies. In this regard, the independent consultants undertake rigorous data verification, including, but not limited to, Denison’s field procedures, databases and assay results.
Prior to public disclosure of drilling results, including preliminary radiometric (eU 3 O 8) and chemical assay grades (U 3 O 8), the results are subject to data verification by Qualified Persons employed by Denison. This includes checks of 10 to 20% of the results (typically as composited intervals) against non-composited eU 3 O 8 determinations and laboratory assay certificates.
