Legacy starts first-pass DD at Breccia Sinter prospect

Legacy Minerals (ASX:LGM) has started its first-pass 1,200m of diamond drilling (DD) at the Breccia Sinter prospect, which is expected to take 6-8 weeks.

The first pass drilling will target an area defined by mapped low sulphidation epithermal veins where rock chip samples have graded up to 32.2g/t Au and 290g/t Ag.

Legacy reports soil sampling has also defined a >20ppb Au soil anomaly 500m x 250m in size.

The current drill program is designed to test these high-order soil and rock chip Au-Ag results and the coincident strongly resistive AMT body, which could potentially reflect a feeder structure at depth and the potential boiling zone which may host significant gold and silver mineralisation.

Legacy says the recently defined AMT resistivity anomaly at the prospect supports the potential for a high-grade feeder structure and boiling zone that may be the source of the high-grade gold and silver low-sulphidation epithermal veins mapped on surface.

This is the first diamond drilling on the prospect and the first drilling to test the interpreted boiling zone at depth. The company considers diamond drilling to be critical for understanding the orientations and textures of the quartz veins as well as the nature of the alteration and orientation of the host lithologies.

The Breccia Sinter prospect is defined by an 850m long x 700m wide low-sulphidation epithermal pathfinder soil anomaly. The anomaly is defined by high tenor Au-Ag-Sb-As-Hg soil anomalism associated with crustiform-colloform quartz banded veins and quartz vein breccia outcrop and float trains.

Rock chip sampling here has graded up to 32.2g/t Au and 290g/t Ag.

The confirmation of sinter related lithology from petrologic analysis, the elevated levels of Sb in rock chip samples (up to 276ppm Sb) and dominant chalcedony in crustiform-colloform banded chalcedony-quartz-adularia+/-hematite veins all suggest the epithermal system has not been deeply eroded and remains intact at depth.

The diamond drilling will test the low-sulphidation epithermal vein system with a focus on intercepting mapped surface gold and silver bearing veins at depth to determine the vein structural orientations, epithermal textures, and controls to mineralisation.
