low-sulfidation system hosted in Tertiary volcanic rocks
Escarpe represents a low-sulfidation system hosted in Tertiary volcanic rocks partially covered by post-mineral basalts. Through erosional windows in the basalts several zones of veining have been observed outcropping and subcropping; the type of silica and the textures of the veins along with the geochemical anomalies indicate proximity to the “Bonanza” level.
Samples collected at Escarpe have returned values of up to 1.49 g/t Au, up to 66.1 g/t Ag with anomalous As, Ba, Hg and Sb. Mineralization seems to be controlled by a main NS structure that runs for several kilometers.
Two zones of mineralization have been defined at Escarpe: Central area of around 700 m by 200 m, and southern area of approximately 1.2 km by 200 m. Both areas exhibit the same characteristics: opaline to chalcedonic silica veins, veinlets and breccias with Au-Ag.

Historical Drilling by Radius Gold
1,308 m in eight holes
165 rock-chip samples collected
basic mapping and sampling conducted
Only basic mapping and sampling have been conducted at Escarpe. A total of 165 rock-chip samples have been collected.
Sable is currently waiting for the reception of mineral titles to perform a first round of drilling.
