Melbourne, Australia — August 17th, 2021
Kincora Copper Ltd. (the Company, Kincora) (TSXV & ASX:KCC) is pleased to report further assay results from ongoing drilling 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:
“The wide interval of gold and alteration in TRDD022, and the extensive strike (over 500m) of near surface skarn mineralisation seen in earlier holes, are strong evidence of a large multiple intrusive porphyry gold-copper system at the Trundle Park prospect.
TRDD022 is highly encouraging in that we are potentially very close to our porphyry target. A follow up hole is drilling to the NNW of TRDD022 for the potential higher grade and interpreted core of the targeted system.”
Detailed geological logging of TRDD022 has taken place and noted that the better mineralized zones exhibit interpreted fingers of monzonite intruding a main monzodiorite, in areas brecciated, with strongly developed and variable interpreted outer potassic alteration. This setting coupled with returned mineral tenor, particularly gold intervals, 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 a discrete mineralized footprints of only hundreds of metres width that are vertically extensive and occur in clusters or a series of deposits.
Two rigs remain operational, one currently drilling a scissor hole to TRDD022 at the Trundle Park prospect at Trundle, and the other has commenced a second 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, host to a combined >20Moz gold and >5Mt copper1.

Trundle Park prospect
Kincora’s drilling at Trundle Park has focused on simultaneously testing both the near surface skarn mineralization and underlying causative porphyry source(s), advancing and confirming our working geological model beyond prior explorers’ shallow drilling (average historic depths of only 28m).
Improved geological understanding has provided the confidence and vectors to drill to comparable depths to where the core of similar intrusive systems occur elsewhere in the wider and immediate region, at Cadia and Northparkes respectively. Hole TRDD022 was completed to 940m, the deepest hole at the Trundle Park prospect.
TRDD022 followed up several previous holes that returned potassic alteration with anomalous gold mineralisation, and which now opens up a large previously untested zone to the west and north.

Working Leapfrog model (section LHS & plan view RHS): initial follow up hole to TRDD022, TRDD026 commenced testing an approximate 100m step out to the mineralised zone to the NNW
Assay results have been returned for TRDD022 with significant broad mineralized intervals including 162m @ 0.25 g/t gold, 0.04% copper and 9 ppm molybdenum (from 670m), comprising 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). See Table 1 for further interval details and also Figure 4 of these intervals in relation to the mineralized footprint around the Cadia-Ridgeway orebody.
Detailed geological logging has taken place and noted that the better mineralized zones exhibit generally centimeter scale interpreted fingers of monzonite vein-dyke and associated mineralization intruding the main monzodiorite intrusion. Magnetite stringer veins have also been noted to be associated with pyrite and epidote replacing mafic minerals in the monzonite vein-dykes. Chalcopyrite is present in stringer veinlets on its own and also occurs as blebs or stringer veinlets with pyrite or magnetite. See Figure 7 for examples of rock types in TRDD022.
Figure 4: Mineral tenor and interpreted alteration akin to a proximal setting to the gold rich, high grade-copper Cadia-Ridgeway and the multiple intrusive deposits at the neighbouring Northparkes mine
- Similar exploration approach, geological vectors and target as Cadia-Ridgeway
The encouraging mineralization and lithology in TRDD022 is coincident with intense red alteration, interpreted to be representing both hematite dusting but increasingly correlated with outer potassic (K-spar) alteration along the margins of the monzodiorite stock intruded by the monzonite fingers (petrology studies proposed).
Brecciated monzodiorite with monzonite fingers with strongly developed and variable interpreted outer potassic alteration, along with pyrite and chalcopyrite mineralization, coupled with returned mineral tenor provides encouragement for indicators of a proximal environment to the targeted core of an intrusive porphyry system. Such a setting is not dissimilar to Cadia-Ridgeway and the multiple intrusive deposits at the neighboring Northparkes mine. Macquarie Arc alkalic gold rich porphyry copper systems generally exhibit discrete mineralized footprints of only hundreds of metres width that are vertically extensive and occur in clusters or a series of deposits. See Figure 3 for the alteration and mineralization footprint around the core of the Cadia-Ridgeway deposit and relative to the currently known system at the Trundle Park prospect.
The immediate focus of drilling at Trundle Park is the recently commenced TRDD026, the initial diamond drill ‘scissor’ hole to follow up TRDD022, which is seeking to test the potential for higher grade copper-gold and the interpreted core of the system, approximately 100m NNW from the mineralization zone in TRDD022 (see Figure 3 and 4 for hole location).

Drilling, Assaying, Logging and 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 ALS, 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 all of the logged core.
Sample interval selection was based on geological controls or mineralization or metre intervals, and/or guidance from the Technical Committee provided subsequent to daily drill and logging reports. Sample intervals are cut by the Company and delivered by the Company direct 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 mineralized domains and determine the relationship between mineralization widths and intercept lengths.
True widths are not known at this stage.
Significant mineralised intervals for drilling at the Trundle project are reported based upon two different cut off grade criteria:
- Interpreted near surface skarn gold and copper intercepts are calculated using a lower cut of 0.20g/t and 0.10% respectively; and,
- Porphyry intrusion system gold and copper intercepts are calculated using a lower cut of 0.10g/t and 0.05% respectively.
Significant mineralised intervals are reported with dilution on the basis of:
- Internal dilution is below the aforementioned respective cut off’s; and,
- Dilutions related with core loss as flagged by a “*”.
The following assay techniques have been adopted for drilling at the Trundle project:
- 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 holes TRDD002-TRDD022.
- 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.

|Relationship between mineralisation widths and intercept lengths||· These relationships are particularly important in the reporting of Exploration Results.
· If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.
· If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’).
|· Due to the uncertainty of mineralisation orientation, the true width of mineralisation is not known at Trundle.
· Intercepts from historic drilling reported at other projects are also of unknown true width.
|Diagrams||· Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.||· Relevant diagrams are included in the body of the report.|
|Balanced reporting||· Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.||· Intercepts reported for Kincora’s drilling at Trundle are zones of higher grade within unmineralized or weakly anomalous material.|
|Other substantive exploration data||· Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.||· No other exploration data is considered material to the reporting of results at Trundle. Other data of interest to further exploration targeting is included in the body of the report.
· Historic exploration data coverage and results are included in the body of the report for Kincora’s other projects.
|Further work||· The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling).
· Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.
|· Drilling at the Mordialloc and Trundle Park targets are ongoing at the time of publication of this report and plans for further step-out drilling are in place. Further drilling is proposed at other Trundle project areas that have complementary but insufficiently tested geochemistry and geophysical targets with the aim to find: (a) and expand near surface copper-gold skarn mineralization overlying or adjacent to (b) underlying copper-gold porphyry systems.|
