Collective Mining Identifies a Large Gold Porphyry Stockwork System at Surface Within the Victory Target Area at the Guayabales Project, Colombia  

Press Release Sep 16, 2021

Toronto, Ontario, September 16, 2021 – Collective Mining Ltd. (TSXV: CNL) (“Collective” or the “Company”) is pleased to provide an exploration update on its Victory target (“Victory”). Victory, which is the fifth major target identified through grassroots prospecting by the Company, is in the northern area of the Guayabales Project (“Guayabales”) in Caldas, Colombia. Guayabales is situated contiguous and immediately along strike and to the northwest of Aris Gold’s Marmato gold mine, which contains proven and probable reserves of 2.0 million ounces gold and 4.35 million ounces silver (19.7 Mt grading 3.2 g/t gold and 6.9 g/t silver). The Company interprets the abundant precious metal mineralization encountered throughout the Guayabales Project to be related to multiple mineralized styles that include gold-copper-molybdenum porphyries and associated breccia as well as high grade, precious and base metal vein systems that are superimposed on and enrich the porphyry bodies.

Highlights (Table 1 and Figures 1-4)

  • Victory is a coincidental robust gold, silver, copper and molybdenum soil anomaly with abundant high-grade gold rock chip samples overprinting a magnetic high anomaly.
  • The Victory target is large, measuring 1,000 metres east-west by 600 metres north-south by at least 250 metres vertically (exposed outcrop over different elevations) and is open for expansion in all directions.
  • 22 rock channel and chip samples returned values above 0.5 g/t gold over widths of 1 to 3 metres including 12 samples above 1 g/t gold and a maximum of 6 g/t gold. These samples were obtained from very small outcrop exposures in streams due to Victory being 95% covered by colluvium and landslides. Gold mineralization is related to porphyry veinlets (A, B and Magnetite veins), hydrothermal breccia and a late polymetallic vein overprint with results as follows:

  • An initial drilling program is currently being planned for Victory as part of the Company’s maiden 7,500 metres program currently under way at the Donut target. Drilling at Victory is expected to commence in Q4, 2021.

“Victory is a target area with potential to yield a large, mineralized porphyry system and I congratulate the exploration team for their endeavours in a region with very limited outcrop exposure. Once the Induced Polarization (“IP”) survey is finished, we plan to model all the data and drill test this target in Q4, 2021. The Company has now outlined five targets with porphyry and high-grade vein potential within the Guayabales project in less than six months of exploration work. I am confident that our recently initiated maiden drilling program at the Guayabales project will yield significant discoveries in the near future,” commented Ari Sussman, Executive Chairman.

Details

Victory is located within the northern portion of the Guayabales project and is hosted within fine grained diorites which display potassic and sericite, porphyry alteration. Quartz-magnetite vein stockwork and sheeted vein systems have been identified with vein sets trending NNW and EW. Veins are associated with disseminated pyrite and occasional molybdenite and chalcopyrite. Late-stage veining includes sphalerite and galena sulphides.

Rock chip and soil anomalies at Victory are located directly above a magnetic anomaly as outlined by magnetic inversion modelling of airborne magnetic data. The anomaly has a circular diameter of 500 metres and extends to depth for 900 metres below surface. A clear structural corridor for emplacement of a porphyry system was identified in the field and confirmed with the modelling of the airborne magnetic data.

Field work is continuing at the Victory target and a deep penetrating IP survey is currently being undertaken by Arce Geofisicos using their proprietary AGDAS technology. The survey will generate 3D chargeability and resistivity data for minimum vertical depths of 800 metres and has been designed to search for disseminated sulphide porphyry systems and resistive vein clusters and stockwork.

An NI-43-101 technical report for the Guayabales project is nearing completion and is expected to be filed on SEDAR prior to the end of September 2021.
