LinQ Minerals eyes major gold-copper discovery with first Gidginbung South hole

• First Gidginbung South hole reveals epithermal and porphyry-style features
• Sparse deep drilling leaves a broad alteration zone to test
• Next hole will target the core of a nearby geophysical anomaly

Special Report: LinQ Minerals has logged about 429m of visually identified sulphides and alteration in its first Gidginbung South hole, supporting its interpretation of a potential high sulphidation epithermal and porphyry system beneath cover at its Gilmore project in NSW.

The hole reached 750.3m, roughly 1km south of the Gidginbung pit at the company’s Gilmore flagship project, which hosts resources containing 3.7Moz of gold and around 1.2Mt of copper in NSW’s Macquarie Arc.

LinQ Minerals (ASX:LNQ) interprets the core as showing upper high-sulphidation epithermal-style mineralisation transitioning into deeper porphyry-style veins and alteration.

That combination has spurred management to consider whether the target could sit at the core of a broader system encompassing Gidginbung and the nearby Dam deposit, with the lab assays expected in six to eight weeks to provide further direction.

Following the system deeper

LinQ logged the upper epithermal-style zone from about 321m to 570m, followed by porphyry-style features continuing to the end of the hole.

Pyrite is prominent through the logged interval and LinQ also says it identified copper-bearing minerals visually in parts of the core.

The upper zone lies about 800m south of the previously known southern limit of similar Gidginbung mineralisation while the deeper porphyry-style zone is around 1.6km southwest of comparable mineralisation at Dam.

“It is possible that LinQ has discovered the core part of a large HSE-porphyry system for which Gidginbung and the Dam are smaller components. In geologic terms, this is potentially a big mineralised system,” said LinQ Minerals technical director John Holliday.

A broad search beneath cover

The first hole is only the fourth drilled deeper than 400m along an alteration zone extending at least 7km, excluding drilling within the known Gidginbung and Dam deposits.

That limited coverage leaves LinQ considerable scope to test the depth and extent of the interpreted system and the company considers its new mineralisation open in surrounding directions.

The next hole is planned to test the core of an induced-polarisation anomaly about 200m east of the mineralisation observed in the first. The geophysical response provides a further target to test against the emerging geological picture.

LinQ’s initial plan comprises four holes spaced 200-300m apart and drilled up to 1000m deep, and the company says it may also extend the first hole after reviewing assays.

Gilmore already hosts several resource deposits across LinQ’s 100%-owned ground. Gidginbung South adds another opportunity, with further drilling and assays set to test both the mineral content and LinQ’s interpretation of a larger system.
