Terra Metals (ASX:TM1) continued to define a large and continuous platinum-group-metal, nickel, and copper sulfide system within a newly recognized ultramafic package at the Dante project in Western Australia, according to a Monday filing with the Australian bourse.

Drilling established the Southwest Main Sulfide Corridor, extending over 950 meters along strike, roughly 700 meters wide, and at least 750 meters down-dip, the filing said.

All drill holes encountered extensive and consistent mineralization within a west-dipping ultramafic unit.

Ongoing drilling and surveys continue to refine the geometry and controls on the Southwest mineralized system, with mineralization remaining open along strike and at depth, per the filing.

Shares fell 2% in midday trade on Monday.
