Resolution Minerals (ASX:RML) found a potentially "significant" antimony-silver deposit at the Antimony Ridge mine project within its Horse Heaven project in Idaho, with the receipt of results of 3D modelling of the antimony and silver-bearing veins and vein swarms exposed in past mining pits, according to a Friday filing with the Australian bourse.

The antimony and silver-bearing veins returned high-grade antimony of up to 50% and silver grades of up to 1,420 grams per tonne, the filing said.

Initial metallurgical test results are currently in process, with findings expected to be released soon from two distinct processing options, per the filing.
