Orestone Sampling Confirms Oxide Gold Stockwork Zone and Two New Exciting Exploration Targets at Francisca Gold-Silver Property
Orestone extends its Argentina oxide gold trend by 1.5km and identifies buried porphyry geophysics to de-risk the project.
Orestone Mining Corp. announced Phase I sampling and mapping results from its Francisca gold-silver project in Salta, Argentina. The known oxide gold-silver trend has been expanded to 1.5 km along strike.
The South Gold Zone returned an average grade of 1.04 g/t Au and 7.80 g/t Ag across 332 samples from 13 trenches. High-grade vein intervals grade up to 8.77 g/t Au and 83 g/t Ag.
Reconnaissance mapping identified two new prospective zones: Kelly Gold Zone, characterized by broad stockwork mineralization, and Tom East Zone, which returned 21m at 4.45 g/t Au in colluvium.
Geophysical data shows a 1,700m long IP chargeability anomaly correlating with the oxide trend, with additional anomalies up to 20 mV/V suggesting a potential larger buried sulphide gold porphyry. The company plans to compile results to define drill targets for a Phase I drilling program.
Orestone Mining Corp. (ORS) news confirms the continuation and expansion of the oxide gold-silver trend identified in previous sampling conducted in May and June 2026. The update adds scale with a 1.5 km strike and identifies new targets in the Kelly and Tom East zones, which remain open in multiple directions.
Induced polarization (IP) chargeability data reinforces the potential for a deeper porphyry system, aligning with management's stated exploration strategy. It does not represent a material change in the company's financial position or a new discovery that would immediately alter valuation. The market impact is expected to be incremental, supporting the current exploration narrative without triggering a major repricing.
Orestone Mining Corp. is a junior exploration company focused on gold and copper-gold properties in Argentina and British Columbia. Its flagship asset is the Francisca Gold-Silver Project in Salta, Argentina, which covers 23 sq km under an option agreement to earn up to an 85% interest. The project features an oxide gold-silver stockwork trend and potential buried porphyry mineralization.
The company also holds the Captain Gold-Copper Porphyry Project in British Columbia, which is 100% owned and permitted for 79 drill locations. Management has extensive experience in the mining sector, including former executives from Eldorado Gold and McEwen Mining.
