LAB RESULTS COPPER MINERALISED BRECCIA CAE HOLE 19 AT MT CANNINDAH
Mt Cannindah Hole 19 Assays Return 1% - 2% Cu
Brisbane, June 28, 2023 AEST (ABN Newswire) - Cannindah Resources Limited (ASX:CAE) has now received laboratory results which confirm earlier observations of a significant zone of copper, gold and silver bearing hydrothermal breccia intersected in CAE hole # 19 at Mt Cannindah - see ASX report 19/5/2023. These are the latest developments from the drilling program currently underway at Mt Cannindah copper gold silver project south of Gladstone near Monto in central Queensland (Figs 1 to 3*). Core is being processed and assay lab results are awaited from the bottom of hole # 19. With holes # 20-22, recently being completed, core processing and assaying is underway.
Hole # 23 is currently being drilled in the southern section of the Mt Cannindah Breccia. A major IP survey is also underway across the width of the CAE Cannindah tenements, meaning logistical considerations have to be taken into account to ensure that there is little to no disruption to the smooth running of both the drilling and geophysical operations.
CAE Hole # 19's targeted purpose and preliminary results were reported previously in ASX Announcement 19/5/2023. Some of the key points are repeated here in order to provide context for the lab results. Hole 23CAEDD019 was collared to the south of the main drilled section of the Mt Cannindah mine area, targeting the extent and continuity of copper-gold - silver breccia and intrusive hosted mineralization intersected in sub-parallel CAE holes # 13 & 18. Fig 4* shows the location and key drill intercepts in these holes. CAE Hole # 19 drills between CAE Holes # 13 & 18, with the section containing the trace of CAE hole #13 some 50m to the north west, and CAE hole # 18 some 75m to south east of the trace of CAE hole # 19.
Previously reported results from these holes are show in Fig 4*. See: CAE ASX Announcement 23 March 2023.
Hole # 13 (CAE ASX Announcement 30 September2022) reported the following:
- Drilled two extensive zones (approx. 100m downhole widths of 1% CuEq*) within the primary zone of infill hydrothermal breccia.
- (1) 36m to 140m : 104m @ 1.0% CuEq,(0.63% Cu, 0.41g/t Au, 14.1g/t Ag).
- (2) 229m to 337m : 108m @ 1.01% CuEq,(0.57% Cu, 0.58g/t Au, 9.8g/t Ag.
- CAE Hole #13 also intersected some significant intervals of gold :
- (1) 0m to 24m , 24m@ 2.11 g/t Au, 10.9 g/t Ag, 0.52 % Cu a high grade oxidised gold zone from surface within gossanous hydrothermal infill breccia
- (2) 314m to 329m : 15m @ 2.78g/t Au, which include 4m @ 6.50 g/t Au 9.8g/t Ag. The core of the system here is a prominent semi-massive sulphide infill zone, containing high grade gold with grades up to 22.98 g/t Au, 60.0 g/t Ag, with high Zn, Pb, elevated Bi.
Hole # 18 drills in a south south westerly direction (magnetic direction at collar of 206 degrees). CAE reported results in CAE ASX Announcements 23rd March,2023, and 3rd April, 2023.
Hole # 18 was collared in flinty hornfels, which is cut by an extensive vein fracture network as the Hydrothermal Infill Breccia is approached downhole, crossing the contact at 138.6m.
Copper and gold bearing sulphidic breccia occurs below 138m, cut by some bleached altered, argillized porphyry and thin post mineral andesite dykes. Results reported from the top of CAE Hole # 18 (ASX Announcement, 23March 2023) are highly significant with:
- a high copper breccia zone of 21m @ 0.98%CuEq, 0.75% Cu,0.22 g/t Au,11.0g/t Ag occurring 138m - 159m.
and two high grade gold zones:
- 18m @ 6.34 g/t Au, 0.18%Cu, 17.2g/t Ag (4.18CuEq) (244m-262m) up to 23.93 g/t Au, 61g/t Ag. 20m @ 5.5 g/t Au, 0.81%Cu, 23g/t Ag (4.34CuEq) (355m-375m) up to 23.93 g/t Au, 61g/t Ag, with 1m of 96.16 g/t Au, 1.46% Cu, 123.2 g/t Ag.
The intervals in CAE hole # 18 aggregate to :
- 275m @ 1.03% CuEq, 0.29%Cu, 1.11 g/t Au ,7.9 g/t Ag,4.33 % S (103m-378m) which includes a more sulphidic , higher gold zone of :
- 104m @ 1.22% CuEq, 0.27%Cu, 1.46 g/t Au ,7.5 g/t Ag, (274m-378m)
Hole # 19 is located in the southern section of Mt Cannindah Mine area (see Fig 4) and drills in a south westerly direction (magnetic direction at collar of 216 degrees) with an inclination at the drill collar of -55 degrees.
Fig 5* is a cross section showing simplified geology over the trace of Hole # 19 traverses. Table 1 is a summary geology log. Similar geology to Hole # 18, is noted: collaring in flinty hornfels, which is cut by an extensive vein fracture network, which grades into an hornfels dominated shatter breccia at 131m. At 156m, there is a faulted contact with hydrothermal sulphidic infill breccia, which is clast supported, dominated by angular blocks and fragments of hornfels, some porphyry clasts, with prominent infill of calcite, quartz , pyrite and chalcopyrite. (see Fig 4*) Chlorite is dominant in some of the uphole sections of the breccia, sericite alteration becomes more prominent down hole and dominates from 175m or so. The infill breccia is cut by some bleached altered, argillized porphyry and thin late and post mineral andesite/trachy-andesite dykes, which are often argillized.
Sulphide content is generally high throughout the hydrothermal infill breccia, although there is a variation in chalcopyrite content. Sulphide content can build up to semi-massive levels either side of dykes.
