Sultan has identified a large-scale IP chargeability anomaly at its Big Hill prospect that is typical of copper-gold porphyry targets in the East Lachlan Fold Belt.

The 1km long, 650m wide and 500m deep anomaly occupies the centre of the 5km by 2.5km Big Hill magnetic complex that is interpreted to represent the upper or outer parts of an alkalic porphyry copper-gold system, similar to the major Cadia and Boda deposits.

Adding interest, Sultan Resources (ASX:SLZ) notes that Big Hill includes a coincident 2.2km long by 400m wide north-northwest to south-southeast striking gold and copper key porphyry pathfinder soil geochemical anomaly.

It also includes outcropping copper-bearing rocks and Cadia/Boda equivalent stratigraphy and host rock in the correct structural setting with the target cross-cut by Arc parallel and Cross-Arc structures.

“Sultan’s exploration efforts have rapidly advanced the Big Hill complex from a regional magnetic anomaly with the correct address to what we feel is the standout, undrilled porphyry gold-copper target in the central Lachlan Fold Belt,” managing director Steve Groves said.

“The target is regionally significant, and the recent outstanding IP survey results pave the way for imminent drill testing.”

Big Hill is located smack between Boda about 50km to the north and Cadia to the south in central western New South Wales.

Upcoming activity

Sultan has secured landowner permission and has submitted government approvals for exploration at Big Hill.

Drill planning is well underway for a 10-hole diamond drilling program with a contractor already appointed.

The first three holes are designed to confirm initial interpretations followed by an additional seven follow-up holes.

While final drill designs are still in progress, it is currently envisaged that testing of the strong IP anomalies with supporting magnetic response and surface gold-copper and pathfinder geochemistry will be the priority targets.
