San Lorenzo Cuts Numerous Intercepts of Porphyry Style Mineralization in Holes 9 and 10 on Arco de Oro Target Including 102.3 Metres Of 1.33 G/T Gold
San Lorenzo’s 3.9 km step‑out hits porphyry‑scale gold at Arco de Oro; Hole 10’s 102.3 m of 1.33 g/t Au signals a system far larger than previously imagined.
San Lorenzo Gold has reported new assay results from Holes 9 and 10 at the Arco de Oro target on its Salvadora property in Chile. Hole 9 intersected multiple wide zones of porphyry‑style mineralization, including 58.5 m @ 1.07 g/t Au with a high‑grade core of 1.6 m @ 8.53 g/t Au and 0.75% Cu. Hole 10 returned partial results down to 348 m: a broad 102.3 m @ 1.33 g/t Au, 1.2 g/t Ag, 0.09% Cu, including 13.3 m @ 2.21 g/t Au, plus a separate 37.6 m @ 2.01 g/t Au. The remainder of Hole 10 (to 570 m) shows strong chalcopyrite‑rich mineralization and potassic alteration, with assays pending. These intercepts are a 3.9 km step‑out from the nearest previous hole, indicating a large gold‑rich copper‑gold porphyry system. Phase 7 drilling will commence within 30 days.
These results materially exceed the scale of mineralization previously known at Arco de Oro. The March 2 partial Hole 9 results hinted at a step‑out, but the full results and Hole 10’s long, consistent grades confirm a large porphyry system. The drill hit 102.3 m of +1 g/t Au – a grade‑thickness product that is rare in early‑stage porphyry exploration. The pending deeper assays, where visual signs of strong copper mineralization exist, add immediate upside. This is not a routine follow‑up; it is a material positive discovery that re‑rates the entire Salvadora project. The stock has pulled back from its February highs and this news could reignite speculative interest. It is a material, positive event.
San Lorenzo Gold Corp. is a junior explorer focused on the Salvadora gold‑copper property in Chile’s mega‑porphyry belt, located ~15 km from the El Salvador mine. Salvadora hosts two main targets: - Arco de Oro: A >5 km trend of high‑grade epithermal Au/Ag veins, now recognized as a large porphyry system. Prior core zone hits included 23.3 m @ 4.83 g/t Au and 4 m @ 17.95 g/t Au. - Cerro Blanco: A porphyry target with a >1.5 km alteration zone; previous drilling returned 153.5 m @ 1.04 g/t Au, plus higher‑grade intervals. The company recently expanded the property by adding 2,900 ha through an option on the Rubi Copper Project (Mirasol) and claim acquisitions.
