Ventnor Resources (ASX: VRX) has intersected significant copper from Phase Three drilling at the Thaduna prospect, with extensive footwall mineralisation adding a new dimension to the Thaduna and Green Dragon Copper Project.
The company has discovered broad intersections of primary chalcopyrite in three holes with results unveiling 142 metres of mineralisation, including 97 metres of visible chalcopyrite which terminated in mineralisation.
The indication from the three holes is that primary mineralisation is also present under the Thaduna pit, below 100 metres vertical depth.
The holes were terminated at 233 metres, 228 metres and 233 metres respectively, which is the depth capacity of the reverse circulation rig. Each of these holes had visible chalcopyrite at the end of hole and will now be extended with the diamond drill rig.
The project is located 170 kilometres north of Meekatharra, Western Australia, in the Doolgunna district, and 40 kilometres east of Sandfire’s (ASX:SFR) massive Degrussa project.
The 57-hole program at Thaduna is currently in progress with 25 holes drilled to date. Once completed, the drill program will determine a JORC Resource to a nominal 200 metres vertical depth by extending known mineralisation at Thaduna and Green Dragon, from the previous two drill phases, along strike, down dip and to surface.
Significantly, the company said the "distribution of the copper mineralisation appears to be controlled by the 70 degrees / 340 degrees Thaduna fault and is well constrained to a 3-5 metre wide higher grade zone contained within a 10-15 metre wide broader low grade halo."
This structure was used as an interpreted footwall contact to terminate the holes’ current proposed drilling program, and the holes have intersected primary chalcopyrite mineralisation continuously beyond this predicted footwall contact.
The mineralisation intersected in these holes is also below the depths that were predicted from the previous drilling and is a significant change from that previously reported at Thaduna.
The current Phase Three work program was outlined along with a discussion on the premise that only the oxide and supergene forms of copper mineralisation (chalcocite) had been intersected to date.
Historic reports detailed narrow intersections of primary bornite and chalcopyrite south of the Thaduna pit, 100 metres below the surface.
The results to date provide encouragement to Ventnor who will now extend the drilling programs at both Green Dragon and Thaduna.
The company expects that total reverse circulation drilling will exceed 15,000 metres and a second rig is on site for 2,000 metres of diamond drilling to commence this week. Results are expected mid January.
The copper mineralisation has been confirmed with a hand-held portable XRF analyser. Laboratory results will be required to determine final copper mineralisation grades and the extent of intersections and assay results are pending.
