The Phase 1 exploration program has defined two major veins: the Sarape vein, a northwest trending vein measuring 6.0 kilometres in length and up to 12.0 metres in width, and the Chiltepin vein, a west trending vein measuring 2.6 kilometres in length and up to 3.0 metres in width. Both veins are located either side of a Laramide age horst block. Systematic channel sampling reveals that the western portion of both veins contains barren white quartz and calcite veins that are interpreted to represent late influx and boiling of meteoric fluids during the collapse of the hydrothermal system. The eastern portion of the veins are composed of a separate phase of low temperature, tan green quartz that consistently assays from 0.10 to 0.36 g/t gold across sampled widths, with individual samples assaying up to 3.6 g/t gold.
Neither the Sarape nor Chiltepin vein has ever been drilled.
White quartz and calcite is interpreted to represent hydrothermal system collapse with meteoric fluids drawn down into the faults, heated up and boiled (Calcite crystallises when a fluid heats -- reverse solubility). This part of the vein has extremely low gold, silver or pathfinder anomalism as the precursor fluid was barren. A second quartz phase is green/tan in colour and consistently contains 0.1-0.3g/t gold. Intervals include:
There is a total strike extent of 2.2km of anomalous gold. The green quartz phase is overprinted by a white quartz/calcite phase. Textures in green quartz indicate a high level, low temperature environment above the boiling zone. The boiling zone of the green quartz phase represents a drill target interpreted to occur 100-250m below surface. There is no significant offset along vein length; the entire vein is at the same preserved high level within the epithermal system.
There is the same quartz paragenesis as at the Sarape vein with white quartz and calcite overprinting a green/tan quartz phase. The vein is oriented east-west and located on southern margin of an interpreted horst block. The vein structure is predominantly composed of a massive vein and stockwork of white quartz and calcite. There are small zones of green quartz which are more common in splays containing assay results of:
There is a total strike extent of 1.6 kilometres of anomalous gold. The boiling zone of the green quartz phase represents a drill target interpreted to occur 100-250 metres below surface. There is no significant offset along vein length; the entire vein is at the same preserved high level within the epithermal system.
