02:28 PM EDT, 05/07/2026 (MT Newswires) -- Orestone Mining ( ORESF ) provided initial assay results received from the Phase I exploration program on the Francisca Gold project in Salta Province, Argentina, on Thursday.

The company noted this program included the resampling of existing trenches for which it only possessed historic summary data. Mapping at the South Gold zone indicates a stockwork width from 40-70 metres averaging 50 metres along a 400-500 metre strike length, it said.

"The zone consists of highly sericite argillic altered porphyry and hornfels host rocks cut by a dense stockwork of thin light brown limonite veinlets with thin dark quartz vein centres and thicker dark limonite quartz veins that are both vertical and shallow dipping," said Orestone in a statement. "Assay results for the first two trenches at Francisca compare favorably to historically reported data and confirm that a robust gold-silver mineralized stockwork system is exposed on the surface."

The company's goal is to define a gold-silver deposit that can be mined by open pit.

Shares of the company were last seen down 4.2% at $0.115 on the TSX Venture Exchange.
