Heron Resources has commenced drilling activities at its wholly-owned Woodlawn Zinc-Copper project located 50km northeast of Canberra and 250km southwest of Sydney.
“Following the successful completion of the Woodlawn feasibility Study (FS) which confirmed robust project economics, the company has initiated a 2,500m diamond drilling program targeting northern extensions to the known massive sulphide lens system,” the company told the ASX.
“Drilling commenced on 5 July 2016 with the first of these northern target holes. The estimation of the Minerals Reserves as an integral part of the FS, along with the resultant strong development case, has allowed a shift in focus from resource definition drilling to discovery target testing, with the Northern Expansion the first target to be evaluated.”
According to the company, the primary target is a strike extension to the 4.8Mt “B” Lens with secondary targets being the strike extensions to the 1.3Mt “D” Lens and 0.5mt “I” Lens.
“The B Lens was one of the main mining areas of the former underground, presenting good widths and grades,” reads the statement.
“The target area remains untested from surface due to an evaporation dam dating from the early 1980s which prevented access to a suitable drill position; however the level of water within this dam is now low enough to allow pad construction and drill rig access.”
Heron said the drilling program will utilise down-hole EM geophysical surveying to assist with targeting follow-up drilling after completing the first hole in this campaign.
“Whilst the EM survey is being performed, a drill hole into the recently discovered Lisa Lens will be undertaken targeting an expansion to the known limits of this lens.”
In addition to the Woodlawn Zinc-Copper project in NSW, Heron holds a significant high quality tenement holding in the Lachlan Fold Belt if NSW and the Kalgoorlie Nickel Project in WA.
