Kincora reports further strong encouragement at Trundle

  • Drilling of the first hole at the Mordialloc target (TRDD002) to be reopened and extended, after assay results, independent and internal expert geological assessment support strong halo indicators of a mineralized porphyry intrusion system.
  • TRDD002 intersected favorable alteration and anomalous metal levels between 721-790.25 metres (end of hole), and included up to 0.29% copper and 272ppm molybdenum1.
  • An incomplete second hole at the Mordialloc target (TRDD005 located 150 metres south of TRDD002) has intersected volcanoclastic sandstone and agglomerate at 632 metres, and over 12 metres down hole with improved epidote-chlorite alteration and visual quartz-calcite-pyrite-chalcopyrite mineralization. Drilling to shortly resume after scheduled break.
  • Holes TRDD003 and TRDD004 at the Bayleys and Trundle Park targets have been completed at 721.5 metres and 694 metres respectively, within interpreted fertile porphyry settings, assay results and further geological interpretations are pending. Further follow up holes at Trundle Park and the Mordialloc targets are planned.
  • Experienced and successful exploration manager Dr. Paul Cromie appointed to newly created “Exploration Manager Australia” as the scope of the ongoing drilling program is expanded from existing cash reserves.

VANCOUVER, BC – July 23, 2020 – Kincora Copper Ltd. (the “Company”, “Kincora”) (TSXV: KCC) is very pleased to report further strong encouragement in our search for the core, ore-grade parts of a cluster of porphyry copper-gold systems at the brownfields project at Trundle on the Macquarie Arc of the Lachlan Fold Belt in NSW, Australia.

John Holliday, Technical Committee chair, and Peter Leaman, Senior VP of Exploration, commented: “Assay and petrography results for the second hole at the Trundle project strongly supports the presence of a mineralizing porphyry copper-gold system at the Mordialloc target, confirming previously announced visual and internal interpretations.  Our initial and ongoing follow up hole, TRDD005, certainly reinforces this view.

These results coupled with the nature of the pipe like, high-grade “finger” porphyries in the Macquarie Arc, which are vertically extensive but horizontally discrete, suggests TRDD002 ended in an ore-proximal environment. Extension of TRDD002, and additional step out holes are planned seeking the core of the targeted system, with TRDD005 already providing very encouraging results.  Such a vectoring from drill hole indicators was the exploration approach that was the key to the discovery of Cadia-Ridgeway, the majority of the Northparkes deposits and Alkane’s success at Boda.

TRDD002 is the first hole to search to such depths. The positive indications in these first two holes drilled at Mordialloc see the target remain open in all directions and to depth”. 

President and CEO, Sam Spring commented, “The first holes of Kincora’s maiden program at Trundle, at the Trundle Park, Mordialloc and Bayley’s targets, are across ~10km N-S strike. Initial drilling provides encouragement for a cluster of fertile porphyry targets and world-class scale potential, in a brownfield setting to Northparkes, warranting further drilling beyond the initial scope of the previously announced six hole program.

Our maiden six hole program at Trundle commenced during the first COVID-19 wave in Australia. It was designed to test three porphyry targets with two holes at each target and leaving the Company well funded.

The conservative nature of this program was prudent given the onset of COVID-19 and associated market uncertainties, and to ensure the program could be expanded within existing cash reserves.

Current market conditions have moved significantly in a positive direction for junior explorers with good drilling results. In particular, the gold price is at near 8-year highs, recently moving in positive correlation and lagging a strongly rising copper price; it is a great backdrop to be exploring for gold rich copper porphyries.

With very attractive peer group valuations to other Australian based exploration success stories it is exciting to start expanding the scope of the existing program.

The addition of Paul Cromie as “Exploration Manager Australia” is very well timed in a senior project based role. Paul is an extremely high calibre and successful leader and explorer. Paul will assist oversee the acceleration of exploration at Trundle and across our district scale 1732km2 portfolio in the Lachlan Fold BeltThe Kincora board are very pleased to welcome Paul to the team”.


The Mordialloc target

Previous explorer drilling at the Mordialloc target and the assay results of TRDD002 have returned metal grades comparable to the surrounding parts of the Northparkes deposits and Cadia-Ridgeway within inner- to outer propylitic style hydrothermal alteration.

Visual results from ongoing drilling at TRDD005, the second Kincora hole at the Mordialloc target and follow up located 150 metres south of TRDD002, demonstrate a volcanoclastic sandstone and agglomerate host rock sequence at approximately 632 metres, and over 12 metres down hole with improved epidote-chlorite alteration and visual quartz-calcite-pyrite-chalcopyrite mineralization materially more intense in comparison to TRDD002. From 643 metres, an 0.5 metre interval with abundant pyrite-epidote-chlorite is overprinted by quartz-calcite-pyrite-chalcopyrite-sphalerite-hematite along veins.

Drilling of TRDD005 is ongoing and will shortly resume after the current scheduled break.

A petrographic review of TRDD002 by Dr. Tony Crawford provides further encouragement to Kincora’s interpretation of having intersected strong halo indicators and of being on the margin of a high-level, preserved porphyry system.

“The well defined inner- to outer propylitic style hydrothermal alteration, preservation of hydrothermal magnetite at the base of the hole indicate a passage into typically ore-proximal potassic- or calc-potassic alteration, and the late, probably structurally controlled phyllic overprint at 711.5m with minor anhydrite, all strongly support the presence of a mineralizing porphyry copper-gold system at the Mordialloc prospect.

Similar propylitic epidote-chlorite-pyrite-calcite-prehnite alteration haloes surround potassic and calc-potassic alteration zones at Cadia Ridgeway and Northparkes. The coexistence of epidote with prehnite and well-formed hydrothermal titanite in TRDD002 is significant. Prehnite is a common mineral in the outer propylitic zone at Cadia Ridgeway and titanite occurs in the transition zone between potassic and propylitic alteration as well calcite-prehnite-titanite-pyrite being an assemblage documented from the inner propylitic zone at Ridgeway“.

Fine grain chalcopyrite with increased veining and pyrite was evident at the end of the hole

Drill hole TRDD002 was completed to a depth of 790 metres, relative to an original target depth of 700 metres.  The hole intersected an intrusive complex of quartz monzodiorite, quartz monzonite and quartz monzonite porphyry bodies intruded into a predominantly calcalkaline volcaniclastic sequence of fragmentals and andesite flows.  The lithologies generally display well-developed propylitic alteration throughout consisting of epidote + pyrite + chlorite ± prehnite and hematite dusting of feldspars, with local occurrences of chalcopyrite. Alteration intensity increases significantly to the end of the drill hole with higher temperature inner propylitic zone actionolite and magnetite occurring as vein selvedges indicating possible proximity to a mineralized potassic core.

Further drilling in addition to the extension of TRDD002 and ongoing TRDD005 is proposed to vector and pursue positive alteration patterns, mineralization and geophysics at the Mordialloc target to aggressively test the targeted finger porphyry setting and potential cluster of associated mineralized systems. Such a vectoring from drill hole indicators was the exploration approach that was the key to the discovery of Cadia-Ridgeway, the majority of the Northparkes deposits and Alkane’s success at Boda.

Increasing intensity of propylitic alteration down hole in TRDD002 suggests a potentially proximal location to potassic alteration – TRDD002 is to be extended. Drill hole TRDD005 also is shown projected onto the section and is ongoing.

The Trundle project

The Trundle project is located 30km west of the China Molybdenum Company Limited (CMOC) operated Northparkes copper-gold mill and five economic deposits, in the same Northparkes Igneous Complex.

Past explorer drilling has been extensive with the completion of 2208 holes for 61,146 metres but deeper drilling utilising modern exploration knowledge has been very limited.

Over 92% of prior drilling has been to less than 50 metres depth, a depth that the existing major mines in this belt suggest is just too shallow, with just 11 holes beyond 300 metres (0.5% of holes drilled).

Existing significant drill intersections supports vectoring to very compelling targets for Kincora’s ongoing phase 1 drilling program at three existing mineralised systems – Trundle Park, Mordiallic and Bayleys.  These systems have not been drilled since industry leading Induced Polarisation survey’s, including HPX’s proprietary Typhoon system, and magnetic modelling were completed.

QA/QC Procedures

Sampling and QA/QC procedures are carried out by Kincora Copper Limited, and its contractors, using the Company’s protocols as per industry best practise.

All samples have been assayed at ALS Minerals Laboratories, delivered to Orange, NSW, Australia. In addition to internal checks by AS, the Company incorporates a QA/QC sample protocol utilizing prepared standards and blanks for 5% of all assayed samples.

Diamond drilling was undertaken by DrillIt Consulting Pty Ltd, from Parkes, under the supervision of our field geologists.

All drill core was logged to best industry standard by well-trained geologists and Kincora’s drill core sampling protocol consisted a collection of samples over mineralized sections of the logged core.

Sample interval selection was based on geological controls or mineralization, and/or guidance from the Technical Committee provided subsequent to daily drill and logging reports. Sample intervals reflect geological boundaries, are cut by the Company and samples prepared in line with these geological boundaries, and delivered to ALS.

All reported assay results are performed by ALS and widths reported are drill core lengths. There is insufficient drilling data to date to demonstrate continuity of mineralised domains and determine the relationship between mineralization widths and intercept lengths, true widths are not known. The following assay techniques have been adopted:

    • Gold: Au-AA24 (Fire assay), reported.
    • Multiple elements: ME-ICP61 (4 acid digestion with ICP-AES analysis for 33 elements) and ME-MS61 (4 acid digestion with ICP-AES & ICP-MS analysis for 48 elements), the latter report for TRDD001 and former reported for TRDD002.
    • Copper oxides and selected intervals with native copper: ME-ICP44 (Aqua regia digestion with ICP-AES analysis) has been assayed, but not reported.
    • Assay results >10g/t gold and/or 1% copper are re-assayed.

About Kincora Copper Limited

Kincora is an active junior and systematic explorer seeking to make a major discovery in Mongolia, the Lachlan Fold Belt in Australia and other prospective complementary jurisdictions.

Our technical team is credited with multiple discoveries of Tier 1 copper assets. In 3Q’19, Kincora made the strategic decision to opportunistically pursue entry into the Macquarie Arc, in Central West of NSW. This is Australia’s foremost porphyry belt, home to the giant Cadia, Northparkes mines and recent Boda discovery by Alkane Resources.

The Macquarie Arc is synergistic in line with Kincora’s core focus. It offers: the same scale of target (world-class); the same commodity mix (copper-gold or gold-copper); the same mineralized setting (porphyry and/or epithermal gold); supports a similar systematic exploration approach/exploration methods; and, is a region where the team has had significant exploration success.
