Kincora encounters ‘significant’ shallow mineralised zones near surface at Trundle Project

Kincora Copper (ASX:KCC) has uncovered ‘significant’ zones of shallow mineralisation from a diamond drilling (DD) program currently underway across the Dunns North, Dunns South, and Botfield prospects within its brownfield Trundle Project in New South Wales. 

The company says results, which have returned gold grades up to 14.2g/t Au from Dunns North and additional grades of 6.88g/t Au from Dunns South, are ‘very encouraging’ and indicate ore grade mineralisation at relatively shallow depths. 

Speaking to Mining.com.au, company President and Chief Executive Officer (CEO) Sam Spring says drilling is being undertaken across 5 standalone targets across Trundle, and indicates that skarn mineralisation at the Botfield prospect shares similarities to the Southern Extension Zone discovery. 

Spring told this news service that this discovery has been developed over the last 18 months and has been interpreted to potentially be the largest mineralised skarn system in New South Wales.

The CEO notes drilling completed so far has intersected 50m of massive banded magnetite skarn from about 330m vertical depth, and that geophysics suggest that the core of the system is about 250m out to the east and close to surface.      

“We have drilled about 25,000m to date at Trundle and have made 2 technical discoveries. In this next phase we are looking at putting 3,000m into the 5 standalone targets and hopefully getting some economic grades that warrant getting to that milestone of a drillout. 

“…we are looking at putting 3,000m into the 5 standalone targets and hopefully getting some economic grades that warrant getting to that milestone of a drillout”

We need to do more work on Botfield North and South, we have some good numbers near the surface we have announced today that remain open, and we have created a new search space for ourselves there…this current program is all about discovery drilling.

At Botfield you are seeing that 500m close to the surface. We have hit 50m of massive banded magnetite skarn from about 330m vertical depth and the geophysics seem to be working quite well and suggest that the core of the system is still about 250m out to the east and close to the surface.

What we are seeing here at Botfield and the southern extension zone would be the largest mineralised skarn in NSW.

In addition, Spring also reports that spikes in grade, as seen in the results, demonstrate the presence of a productive hydrothermal porphyry system that can generate ore grade intervals. 

It is a really positive sign to see those spikes in grade to show that one has a productive hydrothermal porphyry system that can give you ore grade intervals and effectively an ore body.

“It is a really positive sign to see those spikes in grade”

It is good to be seeing that endowment and that gold rich nature.”

The ceo says these results generate further confidence due to Trundle’s proximity to the Northparkes Mine, which represents Australia’s second biggest porphyry mine with a metal endowment of about 24 million ounces of gold equivalent. 

The key project in our immediate region that we think is a reference point is Northparkes. It is Australia’s second biggest porphyry mine owned by China Moly and Sumotomo that has about 24 million ounces of gold equivalent metal endowment, and has been in production for over 30 years. It has a series of porphyry systems and skarn deposits and is the most direct comparable.”

Spring also notes Kincora’s next move will be to prioritise a follow-up hole at Botfield in order to confirm the interpreted geophysics of the prospect. 

“The obvious one we are prioritising is the follow-up hole at Botfield that we are looking to shortly commence and see if the geophysics and our interpretations are right. We have only skimmed the margin of it and the core is located 250m to the east.” 

Meanwhile, the discovery of these ‘significant’ zones has been made following the establishment of an exploration alliance with EarthAI, a vertically integrated metals exploration company focused on discovering metal ore deposits required to build renewable energy infrastructure.     

With drilling still ongoing, Kincora announces the program is expected to be completed by the end of April / start of May. Exploration is reported to begin at its Condobolin Project, which hosts 3 prospects within a 2km radius and has returned “good” gold numbers near surface. 

Drilling at Trundle is being funded from a raising completed in December 2022, in which the company raised about AU$2.4 million.   

Kincora is an ASX-listed with ambition of becoming Australia’s leading pure play porphyry explorer within the nation’s foremost porphyry belt. The company’s Trundle Project is located about 61km northwest of the township of Parkes in central west NSW within proximity to the Northparkes Mine, which is owned by a joint venture (JV) between China Molybdenum (SHA:603993) and Sumitomo Group.

China Molybdenum currently holds the majority 80% interest while Sumitomo holds the remaining 20%.
