First NSW Hole Intersects Multiple Mineralised Zones
Kincora Copper Ltd (TSXV:KCC) reports that the first diamond drill hole at the Trundle Park target, at the Trundle project in New South Wales, Australia, has been completed at 685 meters depth.
John Holliday, Chairman of Kincora’s Technical Committee, said Hole TRDD001 has confirmed the targeted setting of an adjacent porphyry system to a near surface skarn, analogous to Cadia and multiple other world-class porphyries.
“While early days in our ongoing drilling program, and awaiting assay results, multiple noteworthy positive developments have been achieved from the first hole at Trundle Park,” Mr Holliday said.
“The zones of moderate to higher grade mineralised skarn intersected are thicker than expected, illustrating significant magmatic fluids associated with the adjacent porphyry intrusion system.
“The mineral zonation in the well-developed and quite intense skarns supports, and may provide vectors to, a primary porphyry orebody target within the porphyry intrusion system.
“The visual results of this hole confirm our exploration model and significantly increases both the scale and prospectivity of Trundle Park, with multiple large targets for follow up.”
Hole TRDD001 has intersected multiple skarn zones, including 28m of visually interpreted moderate mineralization from 55m, including a higher-grade 6.5m interval. Previous assay results at Trundle Park include a higher-grade interval of two metre at 20g/t gold, 6.97% copper and 81g/t sliver from 64m.
An adjacent monzonite and monzodiorite intrusion has been intersected, with disseminated chalcopyrite and pyrite supportive of proximity to a potential higher-grade porphyry system/core.
Mr Holliday said the skarn and porphyry intrusion system setting is analogous to Cadia where the Big and Little Cadia skarns have produced an estimated 140,000t of high-grade copper (5-7%) and greater than 1.5Mt iron ore, and were important to the discovery of multiple adjacent deposits that make up the largest porphyry system in Australia.
The average depth of prior drilling at the Trundle Park target is only 28m, and a high priority follow up hole is planned post assay results for TRDD001. In the interim, drilling has commenced at the Mordialloc target, approximately 12.5 km north of Trundle Park, where previous drilling has returned metal grades comparable to the peripheral parts of the Northparkes deposits, with improving grades down hole, open and coincident with an untested deeper geophysical target.
