INFLECTION RESOURCES LTD. Inflection Resources Ltd. provided an update on the ongoing exploration program in New South Wales. Inflection is systematically drill testing a series of 100% owned, copper-gold alkalic porphyry targets located in the covered, northern extension of the Macquarie Arc. The most recent drilling has been focused on the Duck Creek target where strong porphyry-style alteration has been intercepted.
The Duck Creek project is a large alkalic porphyry-related copper-gold style target. The principal 4.5 x 5.0 kilometre target area covers favourable magnetic and gravity features which the Company interprets to be part of the prospective Macquarie Arc volcanic sequence. The broader target area comprises a large 10 x 15 kilometre gravity low embayment within the large regional magnetic high.
The Company considers the geological setting highly analogous to CMOC's Northparkes mine located approximately 200 kilometres to the south. Specifically, the Company is drill testing high-amplitude, complex, curvilinear magnetic patterns very similar to those typical of the intrusion-related signatures of the Macquarie Arc mineralized districts. Furthermore, drilling to-date has intersected strongly hydrothermally altered rocks distinctly characteristic to those adjacent to mineralized alkalic coppergold systems such as Newcrest's Cadia mine and the Northparkes mine complex.
The Company has completed an additional three drill holes, DCKDH004, 005 and 006, testing a variety of different targets in the vicinity of the previously reported holes DCKDH002 and 003 which returned strong porphyry-style hydrothermal alteration. Drill hole DCKDH005 was a 405 metre deep -80º inclined hole drilled 225 metres to the southwest of hole DCKDH002 and intersected porphyritic andesitic volcanics with high-K calc-alkaline to shoshonitic affinities. These units exhibit feldspar-sericite-tourmaline-actinolite-pyrite alteration considered geologically analogous to that often seen in the upper parts of alkalic porphyry systems including Newcrest Mining's Cadia East deposit.
Centimetre scale blebs of bornite were intercepted at approximately 395 metres interpreted to be scavenged from earlier forming bornite veins and remobilised by later intrusive phases. Drill hole DCKDH006 is a -80º inclined hole drilled 380 metres west of hole DCKDH002 to a depth of 420 metres. The hole intersected polymictic volcaniclastics with patchy K-feldspar, quartz- epidote-chlorite-carbonate-pyrite-tourmaline alteration with disseminated actinolite.
Assay results are anomalous for copper with values up to 771 ppm in holes DCKDH005 and 006 and are within the range of values expected in the upper parts of alkalic copper-gold porphyry systems located elsewhere in the Macquarie Arc. Drill hole DCKDH004 is a -80º inclined hole drilled into a separate target located approximately four kilometres to the southeast of hole DCKDH002. Drilling tested a large magnetic low interpreted to represent zones of magnetite depletion.
The hole intersected andesitic volcaniclastics with moderate epidote-chlorite-minor hematite alteration. Weak alteration and geochemistry imply this specific target area has low potential and no further work is planned. Next phase of drilling Once the exceptional period of wet weather that is currently impacting New South Wales comes to an end, the Company plans to mobilise a drill to the Duck Creek project as soon as practically possible to recommence drilling.
The first deep diamond drill hole is planned to test for porphyry related copper-gold mineralisation at depth below the biotite-tourmaline-K-feldspar alteration intercepted in holes DCKDH002, 005 and 006. The first hole will be drilled towards the centre of a broad magnetic low and designed to laterally crosscut as much alteration as possible. The Company interprets drill hole DCKDH002 to be particularly significant as the hydrothermal alteration is consistent with that developed proximal to porphyry deposits in the Macquarie Arc.
The hole also contains zones of anhydrite veining which the Company specifically considers important as its presence suggests fluids may have been derived from an oxided intrusion at depth. A number of additional drill holes are planned in and around the broader Duck Creek district. Based on drill results and the geophysical characteristics of the broader Duck Creek area, the Company believes the potential exists for the area to host multiple coppergold mineralized centres.
Additional drilling will test a variety of different magnetic targets the Company considers prospective for alkalic porphyry-style mineralisation. Inflection has now completed 67 holes totaling 15,540 metres since the inception of the Northern New South Wales drill program across 19 of the 30 principal target areas identified by the Company. High-priority areas at Myallmundi, Trangie, Macquarie and Duck Creek have been identified based on mineralogy and alteration characteristic of other Macquarie Arc hosted Alkalic copper-gold porphyry systems.
