Bowdens  
Silver Project
NSW, Australia
Summary
Kingsgate Bowdens Pty Limited holds four 
Exploration Licences ("ELs") located in the Lue/
Rylstone area of central western NSW. EL 5920 
is divided into two separate areas, one contain-
ing the Bowdens Project, is adjacent to the 
village of Lue and the second to the west of the 
town of Rylstone.
Silver mineralisation was discovered at Bowdens 
in the mid 1980s. Programs of geophysical and 
geochemical exploration had also been under-
taken. During 2012 Kingsgate completed 124 
drill holes for 13,527 metres as a part of resource 
definition program. The new resource estimate 
comprising a total of 567 drill holes for 63,088 
metres was completed in November 2012.
During the year a comprehensive metallurgical 
testwork program was completed as a part of a 
Definitive Feasibility Study (DFS).
Geology
The Bowdens Silver Project is situated on the 
north-eastern margin of the Lachlan Fold Belt. 
Bowdens is hosted by flat-lying Early Permian 
Rylstone Volcanics. The Rylstone Volcanics are 
partially overlain by a sequence of marine sedi-
ments of the Sydney Basin (Shoalhaven Group). 
The Rylstone Volcanics range from 10 to 200 
metres thick and are dominated by silica rich 
volcanically derived rocks.
The silver mineralisation occurs as flat-lying to 
moderately dipping zones of disseminations and 
silicic fracture-filling and is closely associated 
with sulphides of iron, arsenic, lead and zinc. 
High grade silver mineralisation is also hosted in 
steeply-dipping fracture zones which host 
banded sulphide veins.
