The Jupiter Prospect occurs in the eastern half of the MMGP being approximately 15km east-south-east of the Westralia Prospect. The Jupiter Prospect lies within the Jupiter Corridor which is defined as a 2km long north-south trend containing three main syenite intrusive bodies, which from south to north, are termed Ganymede, Heffernans and the Doublejay (previously mined as the Jupiter Open Pit). Several smaller syenite dykes and intrusive bodies are found proximal to the three main syenites, and all are contained within the Jupiter Corridor.
Approximately 150,000 ounces of gold was produced from Jupiter Open Pit during the period 1994-1996. Post the completion of mining activities in 1996, the remnant resources remaining at Jupiter were 800kt at 2.8 g/t for 73,000 ounces (above a 1.5 g/t lower cut-off grade). All remaining resources were situated below the base of what is now termed the Doublejay pits.
Very limited exploration continued at Jupiter post the cessation of mining activities in 1996. Only two drill holes were drilled at Jupiter in the 10 year period from 2000 to 2010. This was the last physical exploration completed at Jupiter until Dacian Gold commenced drilling in September 2013.
Dacian has enjoyed considerable success in its exploration activities at Jupiter in discovering over 1 million ounces of gold. Beginning with field mapping and several reconnaissance drill holes, Dacian Gold geologists have quickly developed a robust exploration model for drilling the Jupiter corridor. Many of the geological observations made by Dacian are consistent with analogous settings seen at the world-class Wallaby deposit, located only 8km to the east
Critical in understanding the control of gold mineralisation at the Jupiter Prospect was the recognition of the north-south striking, shallow east-dipping Cornwall Shear Zone (CSZ). The CSZ outcrops for much of the length of the Jupiter Corridor and is the principal contributor of gold mineralisation observed at the Jupiter pit.
It was the recognition of the CSZ and its interpreted intersection with the Heffernans syenite body, located 1km south of the Jupiter pit, that led directly to the discovery of the Heffernans gold deposit and the Ganymede deposit in 2015.
Dacian has discovered over 1 million ounces of gold in the 1.8km long Jupiter corridor and following a 37,000m RC and diamond drilling campaign between late 2015 and May 2016, a new Mineral Resource in July 2016 , reported:
33.7Mt @ 1.3 g/t Au for 1,349,000 ounces (above a 0.5 g/t Au lower cut off)
Exploration remains ongoing focusing on identification of new near-surface open pit mineralisation and extensions to existing resources within the Jupiter Corridor.
