epithermal silica-carbonate veins with high-level textures
Vinata surface geology is characterized by a number of epithermal silica-carbonate veins with high-level textures and pathfinders’ anomalies; the veins are hosted within a Tertiary ignimbrite sequence deposited discordantly on top of Cretaceous limestones.
Sable drill tested the vein system intercepting low-grade gold mineralization in rhyolite layers, the gold anomaly extends for 700 m along strike and remains open to the west under quaternary coverage.

First Drilling Campaign
2,772 m in 11 holes between October 2019 and February 2020
Second Drilling Campaign
1,738 m in seven holes between November 2020 and January 2021
186 rock samples collected
170 km of GroundMag collected
8.95 km of CSAMT surveys conducted
Two drill campaigns completed
Since the project was discovered by Sable’s geology team, the company has conducted detailed mapping, and collected 186 rock samples. In April 2019 Sable acquired 170 km of GroundMag followed by 8.95 km of CSAMT surveys.
A first drilling campaign was performed between October 2019 and February 2020 comprising eleven holes and 2,772 meters. A second drilling program was designed to follow up the positive results of the first round and it was conducted between November 2020 and January 2021 completing seven holes and 1,738 m. The second round did not intercept significant values and the project stays on hold since then.
Vinata remains a large gold anomaly that deserves additional deeper drilling from the west.
