Collective Mining Discovers High-Grade Tungsten Mineralization in the Shallow Portion of the Guayabales Project’s Apollo System

Toronto, Ontario, November 7, 2023 – Collective Mining Ltd. (TSXV: CNL) (OTCQX: CNLMF) (“Collective” or the “Company”) is pleased to announce that upon receipt and review of recently received detailed assay results on previously completed drill hole core, a high-grade zone of tungsten mineralization has been outlined in the shallow portion of the Guayabales project’s Apollo porphyry system (“Apollo”) located in Caldas, Colombia. The porphyry system at Apollo owes its excellent metal endowment to an older copper-silver and gold porphyry system being overprinted by younger precious metal rich, intermediate sulphidation porphyry veins (“CBM Veins”) within a magmatic, hydrothermal inter-mineral breccia and diorite porphyry bodies currently measuring 520 metres x 395 metres x 915 metres and open for expansion.

  • Tungsten Tri-Oxide (“WO3”) grades in the shallow portion of the Apollo system range between approximately 0.06% and 0.59% with the weighted average grade running 0.25%.
  • Assuming a conservative 50% recovery rate for WO3 and currently quoted metal pricing, the weighted average gold equivalent (“AuEq”) grade of the drill holes within the tungsten rich area at Apollo has increased from 2.87 g/t AuEq to 3.67 g/t AuEq (28% increase in grade). Please refer to Table 1 below for further details.
  • Using a 0.1% WO3 cut-off grade, the volume of shallow mineralization containing tungsten measures approximately 200 metres by 100 metres by 150 metres vertical and is open to the northeast for expansion. The tungsten mineralized area coincides with high grades for gold, silver, and copper within a shallow portion of the Apollo deposit. 
  • Tungsten mineralization is hosted within the mineral scheelite, which is the most common source of tungsten being mined globally.
  • Metallurgical samples have been dispatched to an ALS laboratory in Kamloops, British Colombia to undertake detailed mineralogical and metallurgical test work with initial results expected in Q2 2024.

Ari Sussman, Executive Chairman commented: “Finding high-grade tungsten as part of the mineral suite matrix in the shallow portion of the Apollo system has the potential to significantly enhance economics of the project. Tungsten has been officially designated as a critical mineral to most countries in the world and we are honored to have found the first known source of potentially economic tungsten in Colombia.  We look forward to receiving and analyzing the metallurgical test work results in Q2 2024.”

*AuEq (g/t) is calculated as follows: (Au (g/t) x 0.97) + (Ag (g/t) x 0.016 x 0.88) + (Cu (%) x 1.79 x 0.90)+ (Mo (%)*11.62 x 0.85) + (WO3 (%)*6.54 x 0.50) utilizing metal prices of Cu – US$3.85/lb, Ag – US$24/oz Mo - US$25/lb, WO3 - US$31,000/t and Au – US$1,475/oz and recovery rates of 97% for Au, 88% for Ag, 85% for Mo, 50% for WO3 and 90% for Cu. Recovery rate assumptions for gold are based on metallurgical results announced on October 17, 2023. Recovery rates for copper, molybdenum, tungsten and silver are speculative as limited metallurgical work has been completed to date on these metals. True widths are unknown, and grades are uncut.

** Previously reported gold equivalent grades excluded WO3.  See press releases dated November 19, 2022, January 31, 2023, January 31, 2023, February 23, 2023, March 15, 2023, March 30, 2023, April 11, 2023, April 25, 2023, May 16, 2023, May 30, 2023, June 27, 2023, July 25, 2023 and August 15, 2023 for AuEq calculations.
