Summary:
• Occur within metapelites and metarhyolite, of the Balcooma Metavolcanics
• Two lenses are lead/zinc rich and one is copper rich
• Lens like bodies
• Recent age dating suggests the bodies formed in the Early Ordovician (~480Ma)
• Textures suggest the deposit is a deformed and metamorphosed volcanogenic massive sulphide similar to those in the Seventy Mile range Group.
• Mineralisation is Volcanic Hosted Massive Sulphide type typical of deposits in a back-arc setting “Kuroko type”.
Summary:
At the Surveyor mine, the Dry River South (DRS) main decline was fully refurbished during the year with the first extraction of ore from the Dry River South deposit occurring in June 2018.
During the year, a cased dewatering bore was commissioned. This water bore was strategically located in the lower levels of the historic workings, to allow dewatering to occur from the bottom of the mine, rather than the traditional way of following the water down the decline. This bore worked with great success.
