Collective Mining Drills 216.7m Grading 1.08 g/t Gold Equivalent at Olympus from Near Surface and Significantly Expands the Target Area


TORONTO, May 09, 2022 (GLOBE NEWSWIRE) -- Collective Mining Ltd. (TSXV: CNL) (“Collective” or the “Company”) is pleased to announce assay results for four additional diamond drill holes at the Olympus Target (“Olympus”) within the Guayabales project (“Guayabales”), Colombia. Additionally, revised geological modeling based on the most current data has significantly expanded the target area for follow up exploration. The Company currently has three diamond drill rigs operating at various targets at the Guayabales project as part of its fully-financed, minimum 20,000 metre program for 2022.

“The Olympus target is advancing rapidly due to our exploration work and geological understanding and this has resulted in a 125 percent expansion of the target area. We are extremely excited about the precious metal potential of the system given the broad intercepts of gold and silver mineralization encountered in early drilling, the sheer size of the alteration system and the plethora of high-grade gold and silver-bearing, porphyry related, CBM veins. All the ingredients are in place for Olympus to evolve into a multi-million-ounce precious metal deposit. As our team understands full-well from our prior experience of exploring and developing the Buritic√° project in Colombia, porphyry-related CBM veins can demonstrate robust continuity over significant vertical and lateral dimensions. Analogous to Olympus are both the multi-million-ounce high-grade Marmato and Buritic√° systems, with each deposit measuring more than 1.5 vertical kilometres. The Marmato project is located approximately 3 kilometres to the southeast of Olympus and is situated within the same structurally controlled, porphyry intrusion – CBM vein, corridor,” commented Ari Sussman, Executive Chairman.

Highlights (See Table 1 and Figures 1 - 4)

  • As a result of geological modelling, drilling, underground sampling and detailed mapping, the Company now interprets Olympus Central and Olympus South to be one large interconnected mineralized system measuring up to 1.4 kilometres north-south by 900 metres east-west. The area, which will now be referred to simply as “Olympus,” remains open for expansion to the northwest, west, south and east.

  • Olympus hole OLCC-4 was drilled westward at a 60-degree angle and intersected both the mineralized Eastern and Western zones. The Eastern Zone is hosted primarily within porphyry diorite and has carbonate base metal (“CBM”) veins overprinting it while the Western Zone is hosted predominately within schist country rock impregnated by multiple zones of sheeted CBM veins with results as follow:

    • 216.7 metres @ 1.08 g/t gold equivalent from 73 metres down-hole (Eastern Zone, drill hole OLCC-4)

    • 110.1 metres @ 0.82 g/t gold equivalent from 480.3 metres down-hole (Western Zone, drill hole OLCC-4)

  • Olympus hole OLCC-5 was drilled to the northwest at 70-degree angle and intercepted the Eastern Zone as follows:

    • 59.6 metres @ 1.02 g/t gold equivalent from 11 metres down-hole before crossing into a late phase intrusion which appears to have eliminated the mineralization in this location. Additional patchy mineralization in the Eastern Zone was encountered further down-hole including 25.3 metres @ 0.86 g/t gold equivalent. The Company will focus future drilling in the Eastern Zone along strike to the south where it remains wide open for expansion. Lastly, this hole was not drilled far enough to intersect the projection of the Western Zone.

  • Recent surface mapping and interpretation of drill data has led to a refinement of the Company’s model for the Western Zone. The schist-intrusive contact is shallow dipping and daylights at surface in the west for at least 200 metres of strike. Future drilling will target the untested, shallow projection of the Western Zone. Holes OLCC-6 and OLCC-7 were unfortunately, not drilled deep enough to intersect this Western Zone projection at depth (see Figure 3).

  • Exploration work to date within both historical and current artisanal mines has outlined more than 25 veins. Previously announced chip channel sampling assay results have confirmed the high-grade nature of the veins with precious and base metal grades assaying up to 485 g/t gold, 1,919 g/t silver, 2.86% copper and combined zinc and lead grades in excess of 25 percent. Drilling completed thus far by the Company has been principally focused on the northern portion of the eastern zone and has not therefore tested below these high grade, artisanal mines. An extensive chip channel sampling campaign has been undertaken within the old mines with assay results anticipated in the near term.

*AuEq (g/t) is calculated as follows: (Au (g/t) x 0.95) + (Ag g/t x 0.017 x 0.95) + (Cu (%) x 2.06 x 0.95) + (Mo (%) x 6.86 x 0.95), utilizing metal prices of Cu – US$4.50/lb, Mo – US$15.00/lb, Ag – $25/oz and Au – US$1,500/oz and recovery rates of 95% for Au, Ag, Cu and Mo.
Recovery rate assumptions are speculative as no metallurgical work has been completed to date.

** A 0.1 g/t AuEq cut-off grade was employed with no more than 10% internal dilution. True widths are unknown, and grades are uncut.

*** No significant values reported in this intercept
