Colibri's Option Partner Recieves 2nd Batch of Assays for Drilling Completed at El Mezquite Gold and Silver Project, Sonora, Mexico

Dieppe, New Brunswick–(Newsfile Corp. – September 21, 2021) – Colibri Resource Corporation (TSXV: CBI) ("Colibri" or the "Company") is pleased to announce that its partner, Silver Spruce Resources, Inc. (TSXV: SSE) has reported assay results for the final 10 holes drilled at the El Mezquite Au-Ag property ("El Mezquite" or the "Property"). All holes intersected gold mineralization over variable core lengths. Highlights of the assays received include intercepts of 0.537 grams per tonne ("g/t") Au over an intersection length of 6.1 metres ("m") in hole MEZ-21-016 and 0.502 g/t Au + 24.7 g/t Ag over an intersection length of 4.575 m in hole MEZ-21-012.

The Phase 1 drill program consisted of a total of 2,485 metres completed in 20 holes from eight drill pads (see Figure 1) and was completed on July 28, 2021. Results of the first 10 holes were reported by the Company on September 7, 2021 which included significant Au assays (Au > 0.10 g/t) in nine of the 10 holes reported with a highlight of 0.83 g/t Au over 3.05 metres ("m") in hole MEZ-21-005.

The locations for all holes drilled in the Phase 1 El Mezquite drill program are contained figure 1 and significant assay results from holes MEZ-21-011 to 020 are reported in table 1.

Ron Goguen, President and CEO of Colibri commented: "This is the first drill program completed on the El Mezquite property and we are very encouraged that gold mineralization has been intersected in nineteen of the twenty holes drilled. The locally high-grade base metal values are also encouraging, and we look forward to our partners utilizing all data to continue to develop the property exploration strategy and test targets in future drill programs."

Greg Davison, Silver Spruce Vice-President Exploration and Director commented: "Pathfinder elements (Hg, Cu, Pb, Zn, Sb and As) with low grade Au often displayed well-defined metal haloes adjacent to notable Au values. These zones, which occurred in fourteen (14) drill holes, ranged from ten (10) to forty-three (43) metres, with seven intervals over 20 metres in apparent thickness downhole, within and peripheral to the multiple gold and silver-bearing intervals."

Silver Spruce Resources is currently in the 2nd year of a four year agreement with Colibri to earn 50% of the El Mezquite Gold and Silver Project. For full details of the agreement please refer to the Colibri news release dated June 11th, 2020.
