Sultan Resources Targets New Gold-Copper Discoveries in Lachlan Fold Belt

Exploration Revival in a Premier Gold-Copper Province

Sultan Resources Limited (ASX:SLZ) has unveiled a fresh wave of exploration targets within its Lachlan Fold Belt (LFB) tenements, a region renowned for hosting some of Australia’s most significant porphyry gold-copper deposits. The company’s recent review of existing geological and geophysical data has spotlighted three priority targets; Ringaroo, Gowan Green, and Razorback-Wattle Ridge; each exhibiting compelling signs of mineralisation that warrant immediate follow-up.

The LFB is home to major discoveries such as Alkane Resources’ Boda-Kaiser deposit and Newmont’s Cadia East mine, underscoring the strategic importance of Sultan’s holdings. Covering 165 square kilometres across three tenements, Sultan’s portfolio sits within the northern reaches of the Molong and Rockley-Gulgong Volcanic Belts, key components of the Macquarie Arc, Australia's premier porphyry Au-Cu province.

Ringaroo, An Open-Ended Gold-Copper Anomaly

The Ringaroo target, located at the northern end of EL8735, features a robust 1km by 0.4km gold-in-soil anomaly exceeding 3.1 parts per billion. This anomaly aligns with a magnetic high interpreted as a magnetite-bearing volcanic and intrusive complex, and overlays a significant IP chargeability anomaly. Notably, Ringaroo lies immediately south of Impact Minerals’ Apsley porphyry prospect, which has reported high-grade copper rock chip samples up to 7.73% Cu, suggesting a fertile mineralised corridor that Sultan is eager to explore further.

Sultan plans to extend soil sampling to close off the anomaly boundaries and conduct additional IP geophysical lines to detect further subsurface conductors, aiming to generate drill-ready porphyry targets.

Gowan Green and Razorback-Wattle Ridge, Historical Riches and Untapped Potential

In the southwest corner of EL8735, the Gowan Green and Razorback-Wattle Ridge targets reveal multiple gold-in-soil anomalies associated with copper and pathfinder elements. Historical workings at Gowan Green have yielded rock chip samples with exceptional grades; up to 26.1g/t gold, 65.5g/t silver, and 24.6% copper; highlighting a base and precious metal-rich system. The presence of outcropping skarns and altered volcanic rocks further supports the existence of a large-scale hydrothermal system.

Razorback-Wattle Ridge presents a complex porphyry system with surface evidence of alteration and mineralisation, including a 1km-long skarn breccia. Although previous drilling focused on the skarn yielded modest results, signs of increasing copper and gold grades with depth near an untested IP chargeability anomaly suggest proximity to a significant mineralised source. Sultan intends to expand soil grids and undertake detailed surface mapping to refine drill targets here.

Funding and Forward Strategy

Proceeds from Sultan’s recent capital raising will support early-stage exploration activities, including fieldwork, geophysical surveys, and drill target preparation. The company aims to commence groundwork within the current quarter, subject to funding and operational conditions, and is actively assessing new opportunities to broaden its portfolio. Chairman Lincoln Liu emphasised the company’s commitment to unlocking value through systematic exploration and modern techniques, signaling a renewed focus on discovery in this highly prospective region.
