Assay register

Read the interval. Keep the context.

Source-linked chemical assay intervals, with original units, transparent conversions and the relationship between parent and included results.

Selected issuer disclosures. This register contains 23 reported intervals from 3 disclosures, including 5 nested subintervals. It is not a complete exploration database or a ranking of companies. Dates refer to publication of the source, not a new drill campaign. True width is not determined here.

18 matching intervals. Reviewed Sep 10, 2026. Included intervals overlap their parent and must not be added to it.

What can be compared

Percent, ppm and g/t concentrations can be put on the same mass basis for the same analyte. U3O8 remains U3O8; it has not been converted to elemental uranium. Radiometric equivalent grades and counts per second are not chemical assays and are excluded. Grade-length products alone do not establish geological continuity, contained metal, recovery or value.

Coverage and original methods

NexGen Energy Ltd · Dec 1, 2025

All 16 interval rows in Table 1 for RK-25-256, including three subintervals. Issuer reports a 0.01% U3O8 cutoff, a minimum downhole interval of 0.5 m and maximum internal dilution of 2.0 m. Open original disclosure ↗

Skyharbour Resources Ltd · Jan 14, 2026

Five new assay intervals described for ML25-15, ML25-12, ML25-01 and ML25-14. Historical comparisons and radiometric results are excluded. This is not all drilling or all sampling in the program. Aggregation cutoff and internal dilution are not specified for these narrative intervals in this release. Open original disclosure ↗

Talon Metals Corp. · Sep 9, 2026

The issuer-reported 46.43 m parent interval and its 26.22 m included interval in drill hole 25TK0562A are recorded here as nickel assays. Other metal grades remain in the original disclosure. Table 1 identifies selected assay intervals; no additional cutoff or internal-dilution rule is asserted in this register. Open original disclosure ↗
