Last year, Sultan Resources undertook its maiden diamond drill program at the Razorback Ridge gold-copper prospect in Central NSW – and all assay results have now been received.

As part of the Big Hill gold-copper porphyry project in the company’s Lachlan Fold Belt (LFB) portfolio, the drill program was designed to target the structural host beneath outcropping high-grade copper and gold mineralisation at Razorback.

All holes intersected a strongly altered and veined structure containing sulphide minerals that correlates with surface mapping and sampling.

Plus, the results show elevated levels of porphyry-style mineralisation in elements such as gold, silver, copper, arsenic, antimony, molybdenum, and tungsten.

Potential for copper-gold at Big Hill

Sultan Resources (ASX:SLZ) said the drilling has confirmed the potential for the discovery of porphyry copper-gold mineralisation at Big Hill – and provided important vectors towards the most prospective part of the system.

With the Lake Grace Nickel Prospect becoming the priority focus for Sultan early in 2022, work at the LFB suite of projects over the next 6 months will concentrate on further identifying priority deeper drill targets at Big Hill, Tucklan and Ringaroo.

This will include reprocessing of existing geophysical datasets and potentially further acquisition of geophysical data in conjunction with surface mapping and sampling.

The company will complete limited percussion drilling to further define porphyry-related alteration zones and allow construction of 3D alteration vectors towards deeper drill targets if required.
