  • Most recent drill hole TRDD026 has intersected multiple broad intervals of porphyry style intrusions at the Trundle Park prospect (assay results pending);

  • TRDD026 is a follow-up scissor hole to TRDD022 (162m @ 0.24 g/t gold and 0.04% copper) and has extended the porphyry system approximately 100m on strike and up to 115m down dip;

  • Alteration, host lithology, intrusive suite, depth and size of system typical of the multiple intrusive porphyry deposits at the neighboring Northparkes mine;

  • A wedge drilling off from previous hole TRDD014 (65.5m @ 0.25g/t gold and 0.04% copper) has commenced, seeking to further extend and connect the intrusive systems returned in both TRDD014 and TRDD022;

  • The direction south from TRDD022 remains for future drill testing after the completion of the wedge off TRDD014.

MELBOURNE, Australia, Sept. 23, 2021 /CNW/ - Kincora Copper Limited (the Company, Kincora) (TSXV: KCC) (ASX: KCC) is pleased to provide an exploration update from ongoing drilling at Trundle Park prospect situated at the brownfield Trundle project, located in the Macquarie Arc of the Lachlan Fold Belt (LFB) in NSW, Australia.

John Holliday, Technical Committee chair, and Peter Leaman, VP of Exploration, noted:

"TRDD026 tested and better defined the NNW potential from TRDD022 intersecting two zones of the targeted system, for which assay results are pending. While we have not yet intersected the systems core we are seeing the encouraging right signs and are deepening an adjacent hole (TRDD014W1).

TRDD014W1 seeks to test the target deeper below TRDD022 and to the SSE, and to determine if the mineralization in TRDD022 (including 46m @ 0.54 g/t gold and 0.08% copper) and TRDD014 (including 10m @ 0.73g/t gold and 0.1% copper) are related, and proximal to the potassic core of the system. Also, we are planning future holes to test the open direction to the south of TRDD022 and TRDD014."

Two rigs remain operational, one currently drilling a wedge off TRDD014 at the Trundle Park prospect at Trundle, and the other has commenced a fourth hole at the Gateway prospect at the Fairholme project.

Trundle and Fairholme are both advanced exploration stage projects with hallmarks of neighbouring deposits, Northparkes and Cowal respectively, with assay results from recent drilling pending.

Trundle Park prospect

Recent drilling of hole TRDD022 by Kincora observed significant broad mineralized intervals comprising 162m @ 0.25 g/t gold, 0.04% copper and 9 ppm molybdenum (from 670m), including 46m @ 0.54 g/t gold and 0.08% copper (from 684m) and 18m @ 0.75 g/t gold and 0.09% copper (from 712m) (announced August 16th, 2021: "Significant gold bearing intervals at Trundle Park"). The results of TRDD022 revealed a large previously untested zone at depth, open in all directions. It provided the greatest 'proof of concept' support to date for Trundle Park to host a porphyry intrusive system, potentially with ore grades.

Detailed geological logging and petrographic analysis of TRDD022 has noted that the better-mineralized zones are in brecciated areas, with strongly developed and variable interpreted outer potassic alteration. These better-mineralized zones exhibit generally centimetre-scale interpreted fingers of monzonite vein-dyke and associated mineralization intruding a monzodiorite intrusion.

TRDD026, the initial diamond drill 'scissor' hole to follow up TRDD022, sought to test the potential for higher-grade gold-copper and along strike approximately 100m NNW from the mineralization zone in TRDD022. TRDD026 has intersected multiple intrusive phases providing further confirmation of, and extension to, the targeted porphyry system.

Figure 3: TRDD022 and TRDD026 provide convincing and increasing evidence of a multiple phase, multiple intrusive system with demonstrated mineral tenor with analogous lithology and alteration to the targeted intrusive porphyry systems that occur elsewhere in the wider and immediate region (at Cadia and Northparkes respectively)

Porphyry system target confirmed and extended: TRDD022 and TRDD026 provide convincing and increasing evidence of a multiple phase, multiple intrusive system with demonstrated mineral tenor with analogous lithology and alteration to the targeted intrusive porphyry systems that occur elsewhere in the wider and immediate region (at Cadia and Northparkes respectively) (CNW Group/Kincora Copper Limited)

(c) Plan view of the Trundle Park prospect

TRDD026 intersected the targeted monzonite intrusion in two zones:

  1. Within a footwall to a westerly dipping fault where quartz-monzonite with strong sericite alteration and quartz-carbonate veining, and breccia fill was observed (711m to 749m down hole). This interval is visually interpreted to be similar in mineral composition to the quartz-monzonite observed in TRDD022 (670m to 730m down hole) which is potassic altered and along strike towards the south in relation to TRDD026 (see Figure 5 (b)). The intersection of the approximately 40m estimated near true width of the targeted lithological unit (quartz-monzonite) is encouraging.

  2. A multiphase felsic intrusion sequence was then intersected from 746m to 826.9m, interpreted to be representative of the true width of this unit of the system (eg approximately 80m). This zone is dominated by monzodiorite, with interpreted later intrusions of minor quartz monzonite exhibiting patchy potassic alteration and also quartz monzodiorite with chlorite-silica alteration.
    The potassic altered quartz monzonite, with chalcopyrite mineralization (see Figure 5(d)), in TRDD026 at 750m down hole depth appears similar to and is interpreted to be related to the potassic altered quartz monzonite in hole TRDD022 at 715m depth containing elevated gold and copper. Importantly, this interpretation supports potassic alteration occurring approximately 100m along strike and to the north of TRDD022.

See Figure 5 for examples of rock types in TRDD026 and interpreted equivalent units to TRDD022 with Figures 3 and 4 illustrating the current intrusive model and interpretation at the Trundle Park prospect.

The multiple phase, multiple intrusive setting returned in TRDD022 and TRDD026, coupled with returned mineral tenor in TRDD022 provides indicators of a proximal environment to the targeted core of an intrusive porphyry system. The multiple intrusive deposits at the neighbouring Northparkes mine and at Cadia-Ridgeway exhibit such a setting around discrete mineralized cores of only hundreds of metres width that are vertically extensive and occur in clusters or a series of deposits. See Figure 4 for an example of the working alteration and geological model of the Trundle Park prospect relative to the E48 deposit at Northparkes.

A wedge drilling off the previous hole TRDD014 has commenced. This hole TRDD014W1 is seeking to test the vertical extent of the main mineralized zone in TRDD022 (46m @ 0.54 g/t gold and 0.08% copper) down dip and on strike to the SSE, and horizontally to the NNW from TRDD014 (10m @ 0.73g/t gold and 0.1% copper). Importantly, TRDD014W1 seeks to determine the potential for the mineralization in these two holes to be related, and proximal to the potassic core of the currently defined intrusive system.

Figure 4: Interpreted structurally controlled sericitic overprinting alteration phase intersected in TRDD026 adjacent to potassic alteration in TRDD022 supports a further potential mineralising event within the porphyry system at Trundle Park

  • Pervasive fault/fracture controlled sericitic alteration often occurs in the centre of Northparkes/Goonumbla district mineralised systems and extends to depth

While sericitic alteration in the traditional porphyry model is generally associated to be located in a higher level in the system, deep-level sericite alteration often occurs overprinting or adjacent to the core of the E48, E26, E27 and E22 porphyry deposits and E44 skarn deposit at the neighbouring Northparkes system.

Photos of selected intervals which are not representative of the mineralization hosted on the whole property or Trundle Park prospect but are of the alteration and lithology's intersected in the mineralized zones in these sections of drill holes TRDD022 and TRDD026, and current working geological interpretation presented in Figure 3. There is insufficient drilling data to date to demonstrate continuity of mineralized domains and determine the relationship between mineralization widths and intercept lengths, true widths are not known.
