Collective Mining Expands the Main Breccia Discovery at Apollo and Drills 265.75 Metres at 2.44 g/t Gold Equivalent

  • APC-8 intersected a broad, high-grade zone of breccia mineralization with multiple, overprinting carbonate base metal veins and returned:
    • 265.75 metres @ 2.44 g/t gold equivalent (157 metres vertical).
  • APC-6 also intersected the main breccia zone with some interfingering, mineralized rock flour breccia towards the northern end of the hole resulting in a broad interval as follows:
    • 326.05 metres @ 1.07 g/t gold equivalent (295 metres vertical).
  • As a result of the new drill holes reported today, the maximum dimensions of the Main Breccia have increased to 350 metres along strike by 100 metres across by 500 metres depth (prior dimensions were 300m x 100m x 400m) and remains open in all directions.
  • Drill holes APC-12, APC-13 and APC-14 are now complete at Apollo with the following visual observations from logging:
    • APC-12 and APC-14 intercepted the Main Breccia zone with both holes cutting more than 230 metres of potentially favourable mineralization; APC-13 unfortunately failed before reaching the Main Breccia zone but cut a narrow zone of sheeted veins at a shallow elevation.

Toronto, Ontario, September 13, 2022 – Collective Mining Ltd. (TSXV: CNL) (OTCQX: CNLMF) (“Collective” or the “Company”) is pleased to announce assay results from two additional holes completed at the Apollo target (“Apollo”) within the Company’s Guayabales project located in Caldas, Colombia. Apollo is a newly discovered high-grade copper-gold-silver porphyry-related breccia with previously announced intercepts including the discovery hole APC-2, which intersected 207.15 metres @ 2.68 g/t AuEq and APC-3, which intersected 180.60 metres @ 2.43 g/t AuEq. (See press releases dated August 10th and 29th respectively). As part of its fully funded 20,000+ metre drill program for 2022, there are currently three diamond drill rigs operating at the Apollo target with an additional rig drilling from underground at the Olympus target. 

“Apollo continues to deliver continuous, broad, and consistent zones of well mineralized breccia with overall grades being enhanced by the overprinting, high-grade carbonate base metal veins. Importantly, this remarkable copper-silver-gold discovery continues to grow materially in tonnage as we continue with aggressive step-out drilling in multiple directions. We will remain aggressive for the balance of 2022 and look forward to receiving additional assay results in the near term,” commented Ari Sussman, Executive Chairman.

Details (See Table 1 and Figures 1 – 4)

Seven diamond drill holes with accompanying assay results have now been announced at Apollo and based on results, the Main Breccia at Apollo has expanded and now measures up to 350 metres along strike by 100 metres across by 500 metres vertical. The target remains open in all directions and has the potential to evolve into a significant high-grade, bulk tonnage mineralized system.

Drill holes APC-6 and APC-8 were drilled in opposite directions from two separate drill pads (Pads 3 and 2) to the northeast and southwest respectively and were designed to test the depth and strike continuity of the mineralized breccia previously intersected in holes APC-1, APC-1W, APC-2, APC-3 and APC-5. The following results are highlighted:

  • APC-6:
    326.05 metres @ 1.07 g/t AuEq from 364.60 metres (295 metres vertical) including:
    151.5 metres @ 1.20 g/t AuEq from 480.15 metres down hole, and
    10.55 metres @ 4.64 g/t AuEq from 680.10 metres down hole.

APC-6 is the deepest diamond hole drilled to date and this long intercept consisted primarily of favorable angular breccia with interfingering of rock flour breccia, which is less porous and therefore lower grade. APC-6 was collared from Pad 3 and terminated at a final depth of 759 metres.

  • APC-8:
    265.75 metres @ 2.44 g/t AuEq from 202.00 metres (157 metres vertical) including:
    13.20 metres @ 4.29 g/t AuEq from 202.0 metres down hole,
    18.45 metres @ 4.55 g/t AuEq from 239.05 metres down hole,
    28.45 metres @ 4.18 g/t AuEq from 279.40 metres down hole, and
    15.50 metres @ 5.21 g/t AuEq from 342.6 metres downhole.

APC-8 intercepted continuous mineralized angular breccia with a sulphide matrix consisting of pyrite, chalcopyrite and pyrrhotite which has been overprinted by carbonate-base metal porphyry veins (“CBM”) hosting sphalerite in various locations and particularly in the upper portion of the intercept. The breccia clasts are all quartz diorite and diorite in composition and this hydrothermal system is clearly linked to a porphyry system. APC-8 was collared from Pad 2 and terminated at a final depth of 523 metres.

  • Four rigs continue to drill at the Guayabales project with assay results anticipated in the near term for three holes from Apollo with the following encouraging visual intercepts: 
    • APC-12 and APC-14 tested the Main Breccia discovery at Apollo with both holes intersecting more than 230 metres of potentially favourable mineralization.
    • APC-13 ran into technical difficulties prior to reaching the Main Breccia but intersected a 15 metres zone of sheeted CBM veins at a shallow depth.

The Apollo target area, as defined to date by surface mapping, rock sampling and copper and molybdenum soil geochemistry, covers an 800 metre X 700 metre area. The Apollo target area hosts the Company’s new Main Breccia discovery plus a vein system located above and on the eastern flank of the Main Breccia discovery and the Northern Breccia discovery located 250 metres to the north of the Main Breccia. Multiple additional untested breccia, porphyry and vein targets have been generated and will be drilled in due course. The overall Apollo target area also remains open for further expansion.

*AuEq (g/t) is calculated as follows: (Au (g/t) x 0.95) + (Ag g/t x 0.014 x 0.95) + (Cu (%) x 1.96 x 0.95) + (Mo (%) x 7.35 x 0.95)+(Zn(%)x 0.86 x 0.95)+ (Pb(%)x 0.44 x 0.95) utilizing metal prices of Cu – US$4.00/lb, Mo – US$15.00/lb, Zn – US$1.75/lb, Pb – US$0.9/lb, Ag – $20/oz and Au – US$1,400/oz and recovery rates of 95% for Au, Ag, Cu, Mo, Zn and Mo. Recovery rate assumptions are speculative as no metallurgical work has been completed to date.

** A 0.2 g/t AuEq cut-off grade was employed with no more than 15% internal dilution. True widths are unknown, and grades are uncut.
