Ventnor embarks on DHEM survey at Thaduna
THE DRILL SERGEANT: Ventnor Resources has flagged its intention to undertake Down Hole Electromagnetic, DHEM surveys at the company’s Thaduna Green Dragon project located north of Meekatharra in Western Australia.
Ventnor recently completed four deep RC pre-collared Diamond drill holes at Thaduna for 1,772 metres of drilling.
The holes were collared over a strike length of 800 metres with a planned intersection depth of 280 – 300 metres vertically below the surface and 80 – 100 metres below the prior deepest intersections.
Ventnor had undertaken the drilling to test depth potential below the stronger zones beneath the existing Thaduna pit.

The company said it considered the mineralisation it has encountered while drilling justifies the use of an advanced in-hole geophysical technique such as Down Hole EM to project the known mineralisation to target additional drilling.
The survey will also include an existing hole at Green Dragon as well as an additional hole on the western side of the Green Dragon pit which is currently being drilled.
“From the mineralisation we have seen in the recently drilled diamond core, we are encouraged to survey these holes with DHEM,” Ventnor Resources managing director Bruce Maluish said in the company’s announcement to the Australian Securities Exchange.
“This technique can target the search for deeper mineralisation below our current drill depth of 300 metres below the surface.”
Drilling completed so far by Ventnor has intersected mineralised structures at a vertical depth of 300 metres at Thaduna and 200 metres at Green Dragon.
The company said it expects the DHEM program will map the conductive mineralised structure in excess of 100m away from known mineralisation.
If successful, follow up drilling will be proposed to increase the known strike length and depth of the mineralisation.
The Thaduna Green Dragon project is situated in the Doolgunna district of WA 40km east of the DeGrussa project of Sandfire Resources.
