Transparent arithmetic

The reported 0.05 % converts to 500 ppm of the same analyte on a mass basis. The grade-length product is 0.025 %·m.

MineralPulse calculations from the reported grade and interval
Calculation	Working	Basis
Concentration in ppm	0.05 × 10,000 = 500 ppm U3O8	Mass-unit conversion
Grade × downhole length	0.05 × 0.5 = 0.025 %·m	Source inputs ↗

These calculations are not new assays, true-width estimates, contained metal or an economic comparison. The analyte remains U3O8. No interval has been added to an overlapping parent or sibling.

Aggregation and geometry

Issuer reports a 0.01% U3O8 cutoff, a minimum downhole interval of 0.5 m and maximum internal dilution of 2.0 m. Issuer states true thicknesses have not been determined.

Source and coverage

All 16 interval rows in Table 1 for RK-25-256, including three subintervals. Manual transcription checked against linked issuer disclosures. MineralPulse has not independently sampled or assayed the core.
