Hole SF_26_003 returned 7.15 metres grading 4.78% copper, including 3.60 metres at 9.17%. Copper-bearing intervals were also reported in holes SF_26_001 and SF_26_002. These are downhole lengths.

The company states that true widths have not yet been established and these are initial results from its maiden programme. Two rigs are drilling while further assays remain pending. The release does not report a mineral resource or commercial production.

## Data

### Reported copper drill intervals

Length-weighted copper grades reported for the initial three holes; lengths are downhole, with true widths not established.

Methodology: Assay intervals and weighted-average copper grades as reported by the issuer. Cut-off grade 0.20% Cu; no internal dilution; reported widths are downhole, true widths unknown.

| Hole and interval | Copper grade (%) |
|---|---|
| SF_26_001: 4.00 m from 66.00 m | 1.93 |
| SF_26_002: 2.50 m from 75.00 m | 3.24 |
| SF_26_003: 7.15 m from 85.85 m | 4.78 |
