Orestone Reports First Gold Assays from Francisca Surface Exploration Program
Surface Assays Validate Oxide Gold Model at Francisca, Drilling Phase Now Critical for Valuation

Executive Summary
- Orestone Mining Corp. released initial assay results from its Phase I surface exploration program at the Francisca Gold Project in Salta Province, Argentina.
- The program involved resampling existing trenches to verify historical data, revealing significant gold and silver mineralization.
- Key intercepts include Trench T8 with 23.47 metres @ 4.71 g/t Au (including 6.26m @ 12.31 g/t Au) and associated high-grade silver.
- Geological mapping identified a northwest strike length of 1,100 metres of oxide gold stock-work mineralization.
- The South Gold Zone shows a stockwork width of 40-70 metres underlain by a 400x500 metre circular IP chargeability anomaly suggesting potential for a larger intrusive body at depth.
- CEO David Hottman stated results are encouraging and preparation is underway for Phase I drilling to test the large gold target.
Material Impact
- The news confirms the geological model established during previous mapping phases (Jan-April 2026).
- Grades of ~4.71 g/t Au in oxide zones are consistent with historical surface sampling data reported earlier in 2025, validating the project's potential rather than introducing a surprise discovery.
- The announcement moves the project from "surface exploration" to "drilling ready," which is a necessary milestone but does not yet define a resource estimate or economic viability.
- Given that Phase I completion was announced on April 14, 2026, assay results in early May are expected and incremental rather than unexpected market-moving information.
- The news supports the narrative for continued exploration funding but lacks the magnitude to justify a significant re-rating without drilling confirmation of depth and continuity.
