Collective Mining Reviews 2021 Achievements and Announces Plans for 2022

TORONTO, Dec. 29, 2021 (GLOBE NEWSWIRE) -- Collective Mining Ltd. (TSXV: CNL) (“Collective” or the “Company”) is pleased to review its accomplishments of 2021 and outline its business plan for 2022 for its Guayabales and San Antonio projects. The properties are located in Caldas Colombia and the Company has the right to earn 100% unencumbered interests in both projects.

2021 Highlights

Guayabales Project (Figure 1)

Hole ID From (m) To (m) Interval (m) Au (g/t) Ag (g/t) AuEq* (g/t)
DOC-5 0.0 163 163 1.2 11 1.3
DOC-2 0.0 104.0 104 1.2 12 1.3

* AuEq (g/t) is calculated as follows: (Au (g/t) x 0.95) + (Ag g/t x 0.016 x 0.90) + (Cu (%) x 1.83 x 0.92) + (Mo (%) x 4.57 x 0.92), utilizing metal prices of Cu - US$4.00/lb, Mo - US$10.00/lb, Ag - $24/oz and Au - US$1,500/oz and recovery rates of 95% for Au, 90% for Ag, 92% for 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.

Assays for several completed drill holes remain outstanding and will be announced once received in Q1, 2022.

Sample ID Au (g/t) Ag (g/t) Cu % Zn % Pb%

CM003571 198.7 369 0.08 9.03 12.74

CM003570 34.8 745 2.66 0.18 0.45

*The reader should be cautioned that grab samples are selective in nature and as a result should not be relied upon as being representative of average grades anticipated in any future resource estimate or mining scenario.

** Only samples CM003570 and CM003571 reported above were analyzed for base metal grades.

A maiden diamond drilling program utilizing two rigs commenced at the Olympus target on December 1, 2021, and visual logging of the two completed holes to date highlights the discovery of multiple mineralized CBM veins hosted within intensely altered porphyry diorite and hydrothermal breccia units. Initial assay results are expected in January 2022.

SAC-8 0 710 710 0.40 6 352 130 0.04 0.001 0.53

* AuEq (g/t) = (Au (g/t) x 0.95) + (Ag g/t x 0.013 x 0.90) + (Cu (%) x 1.83 x 0.92) + (Mo (%) x 4.57 x 0.92), utilizing metal prices of Cu - US$4.00/lb, Mo - US$10.00/lb, Ag - $20/oz and Au - US$1,500/oz and recovery rates of 95% for Au, 90% for Ag, 92% for Cu and Mo.

About Collective Mining Ltd.

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 eight major targets have been defined. The Company is fortuitous to have made significant grass root discoveries on both projects with discovery holes of 104 metres @ 1.3 g/t AuEq and 710 metres @ 0.53 AuEq at the Guayabales and San Antonio projects, respectively. ( See press releases dated October 18 th and 27 th for AuEq calculation.)
