The majority of production occurred between 1926 and 1937, 45,657 tonnes were produced averaging 6.63 grams per tonne gold, 223.91 grams per tonne silver, 1.83 per cent lead, 2.43 per cent zinc and 0.026 per cent copper.  Potential exists to develop more reserves, along strike to the present workings and at depth below the No. 4 level. Drilling in 2010 has indicated a zone at least 300 metres long and 200 metres along dip with a true thickness of 6-7 metres. Similar to the ore mined, the gold grade of this new extension shows 5-6 grams/tonne with appreciable silver, zinc, copper and lead.
