Orestone Mining (OTC: ORESF) reports follow-up exploration at the Tom East and Kelly gold zones on the 23 km² Francisca Gold-Silver Project in Salta, Argentina. Work targets expanding the mineralized footprint and defining drill targets along a 1,500-metre northwest-trending oxide gold-silver system.
At Tom East, Phase I trench 6B returned 4.45 g/t gold over 21 metres, with a detailed 200 m by 200 m soil grid now underway. At the Kelly Gold Zone, mapping and rock chip sampling outlined a 50-metre-wide quartz-limonite stockwork grading 0.37 g/t gold and 2.15 g/t silver, underlain by strong IP chargeability anomalies interpreted as related to mineralization.
Orestone (OTC:ORESF) reported Phase I sampling and mapping results from the Francisca gold-silver project in Salta, Argentina. Work outlined a 1,500 m northwest-trending oxide gold-silver system including the North, South, Kelly and Tom East zones.
The South Gold Zone averages 1.04 g/t gold and 7.80 g/t silver from 332 trench samples over 400 m strike. Tom East returned 21 m of 4.45 g/t gold in colluvium, while Kelly shows broad stockwork zones grading 0.24–0.41 g/t gold. A 1,700 m long IP anomaly and localized highs to 20 mV/V suggest potential for a larger porphyry system.
Orestone Mining (OTC:ORESF) completed a MobileMT airborne MagnetoTelluric survey over the T-2 conductivity target at its 100% owned Captain gold-copper porphyry project in British Columbia. The 26 km² survey covered 157 line-km at an estimated cost of $112,000.
The work aims to better define T-2 ahead of the next drill program. Previous drilling at Captain returned gold intervals up to 203 m grading 0.329 g/t gold and 0.06% copper. Orestone also advances the Francisca gold-silver project in Salta, Argentina.
Orestone (OTC: ORESF) expanded its Francisca Gold-Silver Project in Salta, Argentina to 23 km² by acquiring the 14.40 km² Francisca II concession for US$104,000. The company also purchased historic IP, resistivity and magnetic survey data covering a 1x2 km area with strong chargeability anomalies.
Recent trenching at the South Gold zone returned intervals such as 23.47 m at 4.71 g/t gold and 28.54 g/t silver from Trench T8 and 36.97 m at 0.78 g/t gold and 7.20 g/t silver from Trench T7, supporting an oxide gold-silver stockwork system along a 1,500 m trend.
Orestone Mining (OTC: ORESF) will host a live investor webinar featuring CEO David Hottman reviewing the company’s gold, silver and copper exploration portfolio in Canada and Argentina.

Orestone (OTC: ORESF) reported initial Phase I surface assay results from the Francisca Gold Project, Salta Province, Argentina, dated May 7, 2026. Key trench results include T8: 23.47 m @ 4.71 g/t Au and 28.54 g/t Ag (including 6.26 m @ 12.31 g/t Au and 92.40 g/t Ag). Trench T7 returned 36.97 m @ 0.78 g/t Au and 7.20 g/t Ag. Mapping outlines a 40–70 m stockwork width over a 400–500 m strike and a northwest oxide gold stockwork trend outcropping for 1,100 m. Samples were assayed by Alex Stewart International Argentina with QA/QC; Gary Nordin, P.Geo, reviewed the technical information.
