14.4.5.1. Two Boys Location, Mineral Resource and past production
The Two Boys deposit lies 800m south of the HGO gold processing facility. It consists of several narrow shear and quartz vein structures and had a high-grade shallowly north-dipping quartz vein lode which was mined by Barminco from 1997 to May 1998 by decline and room and pillar stoping. The most prominent surface feature is the Barminco box cut for the portal of the decline.
It produced 185,000t at 14.0 g/t for total recovered 82,063 oz

Very extensive info on Two Boys in new Tech Report , includes pics of 5 foot quartz vein with low dip angle which means shallow mining gets a lot more ore than steep dip.

Gold is often visible occurring as coarse gold grains up to several millimetres in diameter (Sheddon 1998) and often occurring
with pyrite, arsenopyrite and galena (Westgold 2018).

Average grade in past underground was 14 grams. If it is half that good in future being they were able to open this mine so fast means capital costs were tiny and it is less than 1 KM from mill. Discussed fair amount in this new video by Huet
