Serpent

Overview

Serpent is a district scale epithermal project focused on a series of gold bearing structural trends within an eight kilometre long trend of kaolinite and illite alteration identified in airborne hyperspectral AVIRIS data. Alteration is hosted in a thick sequence of Oligocene aged (23-27 Ma) ignimbrite tuffs.

The focus of the project is the northeast-striking Cobra structural corridor, a two kilometre long zone displaying a broad shallowing of mineralization styles from the southwest to northeast. Beginning at lower elevations with the uppermost portions of a boiling zone, transitioning to significant chalcedonic and opaline silicification, and ending approximately 100 metres vertically up slope  at the “Silica pool”, a region of opal and kaolinite with strongly anomalous mercury .

Reconnaissance rock sampling from the boiling zone has defined anomalous gold up to 0.95 g/t. Anomalous gold up to 0.52 g/t is also defined in a perpendicular structural trend to the Cobra corridor. The boiling zone broadly occurs at the intersection of these two structural zones.

The exposed vein sets in the boiling zone are composed of fine grained saccharoidal silica with abundant platy quartz after calcite and banding textures. Although indications of boiling are exposed on surface, the fine grained silica textures, together with weak kaolinite-dominant argillic alteration and limited, poorly crystalline illite in the surrounding host rocks are consistent with the uppermost levels of the boiling horizon with potential for bonanza epithermal mineralization preservation at depth.

Three kilometres to the south of the boiling zone, preliminary rock sampling at Ant Hill returned up to 0.4 g/t gold, highly anomalous mercury (6 to 10 ppm) and anomalous silver (37 ppm), arsenic and antimony from a silicified structure.

Recent mapping on the property has identified adularia and strong silicification in multiple additional structures to the north of the Cobra corridor including the 450 metre long “Medusa” silicified structure.

No roads or prospects pits have been identified in the primary Cobra structural corridor, and Orogen believe the entire Serpent property remains untested by drilling.
