Collective Mining Makes a Significant New Discovery at Olympus, Drilling 302 Metres at 1.11 g/t Gold Equivalent From Near Surface

TORONTO, March 15, 2022 (GLOBE NEWSWIRE) -- Collective Mining Ltd. (TSXV: CNL) (“Collective” or the “Company”) is pleased to announce results of the first three diamond drill holes at the Olympus Central Target within the Guayabales project (“Guayabales”), Colombia. The Company currently has three diamond drill rigs operating at Olympus with two rigs testing the Olympus Central Target and one rig at the Olympus South Target as part of its minimum 20,000 metre program for 2022. A fourth diamond drill rig is expected to commence drilling at the Guayabales project prior to the end of March 2022.

“The broad intercepts from the initial drilling results at the Olympus Central Target represent a major gold and silver discovery within the Guayabales project. Our work to date has defined a large area of known mineralization and these results simply represent the beginning of drill testing within this target,” commented Ari Sussman, Executive Chairman. “With multiple drill holes advancing and plans to begin testing other major targets at Guayabales in the near term, including an outcropping copper and gold porphyry system at the Victory Target, there is much to look forward to as our fully funded drill program advances in 2022.”

Highlights (See Table 1 and Figures 1 - 4)

• The Olympus Central discovery hole, OLCC-3, was drilled to the northwest at a 60-degree angle to the center of an induced polarization chargeability anomaly. The drill hole totalled 630.5 metres in length and intersected mineralization up to a vertical depth of approximately 400 metres. Two distinct zones of broad mineralization were encountered in the drill hole.
  
  
  • The first zone in OLCC-3 (“Eastern Zone”), which began near surface in a quartz diorite porphyry intrusion, contains multiple high grade, carbonate-base metal veins (“CBM”) enveloped by broad sericite-pyrite, lower grade halos with results as follows:
    
    
    • 301.9 metres @ 1.11 g/t gold equivalent from 61.7 metres depth including 1.3 metres at 74.91 g/t gold equivalent with visible gold observed within this CBM vein.
      
      
  • The second zone in OLCC-3 (“Western Zone”), which is located further down hole and is hosted within country rocks (schists and metasediments), is impregnated by multiple zones of sheeted CBM veins and enveloped by sericite-pyrite alteration as follows:
    
    
    • 34.2 metres @ 0.90 g/t gold equivalent from 486 metres depth including 0.5 metres @ 12.68 g/t AuEq.
      
      
  • OLCC-3 ended in high-grade mineralization with the final sample from 630-630.5 metres depth averaging 0.5 metres @ 7.64 AuEq.
    

• OLCC-1 was drilled steeply to the west at an 80-degree angle into the southern periphery of the induced polarization chargeability anomaly and intercepted a broad zone of mineralization in the Eastern Zone beginning near surface as follows:
  
  
  • 116.3m @ 1.03 g/t gold equivalent from 30.6 metres depth including 9.6 metres @ 8.05 g/t gold equivalent with visible gold observed locally.
    
    
• OLCC-2 was drilled to the southwest at a 60-degree angle and only intercepted sporadic and moderate mineralization. The hole was drilled outside of the induced polarization chargeability anomaly into an area now interpreted to be a late intrusion dyke that has stoped-out mineralization in a small area at this location.
  
  
• The Olympus target (South, Central and North) covers an area of 1.25 kilometres by 0.75 metres and remains open for expansion.
  
  
• Three additional drill holes have been completed to date with assays pending while another three drill holes are currently advancing within the Olympus Central Zone. As a result of the new grassroots discovery at Olympus, the Company plans to accelerate drilling in 2022 by stepping out along the Eastern and Western Zones of mineralization at various elevations.
  
  
• There are over 50 historical and current artisanal mines that have been identified within the Olympus target to date and drilling completed thus far by the Company has not tested below the vast majority of these mines as the discovery hole, OLCC-3, was drilled in the northern extension of the system. As announced previously, grab samples from within artisanal workings found significant high-grades precious and base metal bearing CBM veins (see press releases announced sampling results dated December 1, 2021, December 14, 2021, and January 12, 2022).

*AuEq (g/t) is calculated as follows: (Au (g/t) x 0.95) + (Ag g/t x 0.016 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.

Collective Mining is an exploration and development company focused on identifying and exploring prospective mineral projects in South America. Founded by the team that developed and sold Continental Gold Inc. to Zijin Mining for approximately $2 billion in enterprise value, the mission of the Company is to repeat its past success in Colombia by making a significant new mineral discovery and advancing the projection to production. Management, insiders and close family and friends own approximately 40% of the outstanding shares of the Company and as a result are fully aligned with shareholders. Collective currently holds an option to earn up to a 100% interest in two projects located in Colombia. As a result of an aggressive exploration program on both the Guayabales and San Antonio projects a total of twelve major targets have been defined. The Company is fortuitous to have made significant grass root discoveries on both projects with discovery holes of 302 metres 1.1 g/t AuEq and 104 metres @ 1.3 g/t AuEq at the Guayabales project and 710 metres @ 0.53 AuEq at the San Antonio project.
