On June 4, 2026, Orestone announced the expansion of the Francisca Gold-Silver Project with the acquisition of the Francisca II concession and the purchase of historic geophysical survey data over the current and new land positions. The Francisca Gold-Silver Project now encompasses twenty-three (23) square kilometres.

With the addition of the Francisca II concession, the mineralized trend now covers a northwest strike length of 1500 metres where an oxide gold-silver stockwork, vein and breccia system is present at surface in numerous large outcropping areas (North cluster, South Zone and Kelly Zone). The outcropping zones are surrounded by a 500 to 1000 metre wide area of strongly hornfels-altered sediments, further defined by a 1700 metre long by 500 to 700 meter wide IP chargeability anomaly of 7.9 mV/V that appears to be related to gold-silver mineralization. Several large, strong IP chargeability anomalies measuring up to 20 mV/V indicate the potential for a larger buried gold porphyry. The oxide gold quartz limonite stock-work trend is associated with quartz feldspar porphyry intrusive dykes and intense sericite clay alteration along a NW-trending fault system (Figure 1).

Comments

The acquisition of Francisca II concession at minimal cost is a very meaningful addition to Orestone’s land position at Francisca as the mineralized trend now covers a northwest strike length of 1500 metres where an oxide gold-silver stockwork, vein and breccia system is present at surface in numerous large outcropping areas in the three major target areas: North cluster, South Zone and Kelly Zone. The purchase of historic geophysical survey data over the current and new land positions adds valuable information which in addition to the field work already completed will aid in defining targets for a planned Phase II drilling program.
