Castillo Copper (ASX: CCZ) has commenced drilling to test a previously identified breccia pipe for high grade copper mineralisation at depth at its Resguardo project in Chile.
This is the first of its three properties to be drill tested this field season, with two reverse circulation holes to around 250 metres depth.
Prior to the commencement of the drilling program, historic open cut and underground workings were surveyed and sampled for copper.
Assay results from this sampling are pending and will be complementary to drilling.
Phase one exploration was completed earlier this year, comprising geological mapping and geochemical sampling to expand the metallogenic and alteration footprint of the copper breccia pipe and surrounding area.
Ground magnetics were also used to clarify the structural setting.
Castillo boasts three advanced drill ready copper exploration properties in Resguardo, Rio Rocin and Posada, all in Chile.
