Large Miocene porphyry and epithermal centre
La Poncha is a large Miocene porphyry and epithermal center that includes two main mineralized zones. Poncha North shows an outcropping Au-Cu porphyry intruding an intermineral diatreme breccia.
Sable drilled 2,216 m on the porphyry stock at Poncha North in early 2022 intercepting long intervals of low to medium grade Au mineralization plus anomalous Cu, Mo, and Ag.
Highlighted intercepts include:
in hole PON-DH-22-01:101.0 m @ 0.32 g/t AuEq (0.19 g/t Au; 0.096% Cu),115.0 m @ 0.32 g/t AuEq (0.19 g/t Au; 0.096% Cu),49.55 m @ 0.32 g/t AuEq (0.18 g/t Au; 0.083% Cu; 47 ppm Mo);
in hole PON-DH-22-02:263 m @ 0.3 g/t AuEq (0.18 g/t Au, 0.082% Cu, 13.7 ppm Mo),and 90.75 m @ 0.28 g/t AuEq (0.14 g/t Au, 0.094% Cu, 25.3 ppm Mo);
in hole PON-DH-22-06:62.8 m @ 0.20 g/t AuEq (0.17 g/t Au; 65 ppm Mo),and 0.65 m @ 936.54 g/t AgEq (287 g/t Ag; 0.187 g/t Au; 0.76% Cu; 12% Pb; 3.78% Zn); among others.
The drilling demonstrated the considerable size of the gold anomaly as well as the Au-rich affinity of the porphyry.

Poncha South is a volcanic center of 26Ma where sulfide-rich veins of intermediate sulfidation affinity have been intercepted in historical drilling by Golden Arrow and Genesis Minerals including 1.21 g/t Au and 3.30 g/t Ag over 266 m (129m to 395m) from hole RC-PC-13 (Golden Arrow press release dated March 27, 2008); and 4.87 g/t Au, 15.9 g/t Ag and 0.49% Zn over 12.15 m from hole 12-PODH-03 (Genesis Minerals press releases dated July 30, 2012 and March 25, 2013).
Sable has also recognized porphyry style mineralization at Poncha South; the target remains untested by Sable.

First Drilling Campaign – Poncha North
2,216 m in 6 holescompleted in May 2022
geological mapping conducted
145 soil samples collected
Excavated multiple kms of trenching
first drill campaign completed
Sable signed an option agreement for the La Poncha Project in March 2020 and since then the Company has conducted geological mapping and collected 753 rock samples and 145 soil samples, several kilometers of trenching.
The company drilled a first campaign at Poncha North from March to May 2022 comprising six drillholes and 2,216 m.
