The Beach Vein prospect is located at the north end of Acheredin Bay and contains three types of distinctive quartz vein textures hosted in variably altered andesite. The main vein system, containing the discovery outcrop, is a 3m long, multi-phase quartz vein system and has been traced 457m along strike. Drusy quartz breccias occur in several areas the largest of which is 30m wide and 120m long. Single-phase quartz veins up to 15cm wide are abundant along the margins of the main vein zone. The main Beach Vein is believed to have been emplaced concurrent with the drusy quartz breccia.
Seven trenches along the trend of the mineralized vein were dug by RAA in 1982. Four of the trenches exposed >3m of mineralized quartz. Several trench samples containing > 1g/t Au were collected along the length of the vein system. Trench BV4 contained 4.96g/t Au and 7.89g/t Ag over 1.2m; trench BV2 located 137m to the SW contained 2.55g/t Au and 6.4g/t Ag over 1.8m.
