Princesa Lara
50 km NW of Santiago, Metropolitan Region, Chile · Development · Au-Cu
Overview
Princesa Lara is a development-stage gold vein project located 50 kilometres northwest of Santiago, in Chile's Metropolitan Region. The property sits in the Cretaceous metallogenic belt, host to significant historic production of gold, copper, and silver.
ASG holds 4,260 hectares of mining concessions — 2 exploitation concessions and 15 exploration concessions — covering the vein system and its extensions. Concentrate production is targeted for Q4 2026.
Geology
The Princesa Lara property hosts 3 kilometres of vein outcrop across three principal structures — the Princesa vein (1.0 km), Vein A (850 m), and Vein B (570 m) — with true widths ranging from 0.5 to 5.0 m.
Mineralized structures are composed of brecciated bands, quartz–sulfide, quartz–specularite, crystalline quartz, and boxwork filled with hematite–jarosite and manganese oxides.
Surface sampling along the Princesa vein returned consistent gold values between 2.0 and 24.0 g/t Au. A high-grade shoot defined at surface runs approximately 250 m in length at 17 to 24 g/t Au — a bonanza-grade intercept that anchors the current drilling program.
Drilling Program
A 1,500 m diamond drilling program is in progress on the Princesa vein to confirm continuity of the high-grade shoot and extend mineralization down-dip. Initial intercepts — including holes PL-02-25 and PL-03-25 — show hydrothermal breccia with a pyrite–chalcopyrite matrix, quartz and specularite bands, and hematite–jarosite boxwork.
Processing Plant
A 5,000 tonne-per-month flotation plant is in advanced development. The final product will be a gold-copper concentrate. Production is targeted for Q4 2026, with initial annual output of ~12,500 oz Au in the first three years and a planned 50% ramp-up thereafter.
