Kincora Copper confirms ‘extensive’ multiple system porphyry complex at Trundle Project

Kincora Copper (ASX:KCC) has confirmed an ‘extensive’ multiple system porphyry complex at its Trundle Project in New South Wales.

The company reports assay results from 4 of the 5 holes drilled at 4 adjacent but separate minerals system targets at Trundle, combined with detailed geological logging of all holes suggest an interpreted proximal setting to the targeted porphyry systems.

Kincora says this setting, coupled with the coincident magnetic response across a long strike which is open both to the north and south, strongly supports the concept that the southern portion of Trundle potentially hosts clusters of ‘high-grade’ and gold endowed porphyry copper and skarn deposits.

Speaking to Mining.com.au ahead of a visit to the Melbourne Mining Club yesterday and then the RIU Sydney Resources Round-up today (10 May 2023), Kincora Copper President and CEO Sam Spring says the results had significant intervals of ‘high-grade’ and localised mineralisation, but also lower grade intervals with alteration.

“The mineralisation suggests we’re in a proximal environment to the core of 4 separate porphyry intrusion related systems, so (we’re) confirming a very extensive gold-copper system. 4 separate parts within that system, each suggesting that we’re pretty close to where you want to be within the system.”

Kincora reports the drilling has confirmed a 3.2km mineralised strike from shallow depths, up to 900m wide, and a vertical depth of greater than 800m. The observed alteration and mineralisation at each prospect drilled during this program are interpreted to be analogous to a proximal setting in comparison to the deposits at the Northparkes and Cadia mines.

The CEO tells this news service a workshop, led by its technical committee, is scheduled for the end of May to undertake an analysis and review, pending results. 

“These results suggest we’re pretty close to where you want to be without having drilled a clear discovery interval”

“These results suggest we’re pretty close to where you want to be without having drilled a clear discovery interval. At the end of the month we’re doing a technical workshop, by that stage all results including the fifth hole, and ongoing analysis and review should be completed to effectively understand where the priorities are for follow-up drilling.

So we’re very encouraged, and these results really confirm our thesis that this southern part of the Trundle licence hosts the potential for a series or cluster of these porphyry type deposits, like what you see at the big projects in this immediate belt, but also porphyry projects globally.”

In the interim, Kincora says a maiden drilling program has started at the Condobolin Project to test 3 near-surface, ‘high-grade’ gold-base metal targets within a 2km radius.

Kincora reports the current phase of drilling at Trundle began in January, and has currently drilled 5 diamond holes for 1,972m across 4 adjacent mineral systems.

At the Botfield prospect, Kincora has completed 2 holes which drill tested a large magnetic high complex coincident with shallow anomalous copper-gold results and an induced polarisation (IP) chargeability high anomaly.

Assay results recorded at Botfield include hole TRDD037 with 2.9m @ 0.62g/t Au and 0.95% Cu within coarse banded chalcopyrite-bornite-pyrite veins from 129m to 132m, including 0.9m @ 2.24% Cu, and 1.75g/t Au from 131m.

This hole also recorded 31m @ 0.16g/t Au, and 0.08% Cu within massive magnetite-pyrite-chalcopyrite skarn over 80% magnetite from 393m to 424m; and 18m @ 0.20g/t Au, and 0.10% Cu within banded magnetite-pyroxene-feldspar skarn with pyrite and chalcopyrite, and less than 30% magnetite from 402m to 420m.

Kincora says visual observations from hole TRDD039 include strong hydrothermal hematite-silica alteration overprinting early feldspar altered volcaniclastic conglomerate and coarse banded chalcopyrite-pyrite vein from 92m to 94m, interpreted to be like the intercept recorded from 129m to 132m in TRDD037.

Spring adds that with these results returned, Kincora was keen to embark on Melbourne and then Sydney today for the RIU conference.

“Given our announcement today being at RIU I’ve always found it’s pretty good that you’ve got high-net worth people, sort of family office guys walking the floor and a few instos that are generally amenable to catching up face-to-face.

They generally don’t walk the floor, but they’re happy to meet if schedules allow, because that’s who the focus for us this week is, catching up with the brokers that have sort of backed the Kincora story in the past and still provide written research. So, it should be good timing in terms of catching up with everyone with these new results out.”

Kincora Copper is an ASX-listed copper exploration company focused on ‘world-class’ copper gold discoveries in the Macquarie Arc of New South Wales. The Trundle Project consists of a single exploration licence covering 167km-square in the Junee-Narromine volcanic belt of the Macquarie Arc, less than 30km from the mill at the Northparkes mine.
