Dieppe, New Brunswick--(Newsfile Corp. - April 19, 2021) - Colibri Resource Corporation (TSXV: CBI) ("Colibri" or the "Company") is very pleased to announce additional results from its first quarter trenching program completed at the Company's flagship Evelyn Gold Project, northwestern Sonora, Mexico. A highlight of the results is four high grade samples, including an assay of 44.9 grams per tonne ("g/t") Au from the El Sahuaro target area.
Highlights of Evelyn Trench Samples
| Sample No. | Area | Au g/t | Ag g/t |
| 220683 | El Sahuaro | 44.90 | 21.2 |
| 220684 | El Sahuaro | 8.24 | 7.9 |
| 220685 | El Sahuaro | 23.30 | 16.0 |
| 220686 | El Sahuaro | 0.90 | 0.5 |
| 220687 | El Sahuaro | 39.60 | 22.7 |
| 220676 | El Sahuaro | 1.14 | 2.6 |
| 220645 | Central Evelyn | 2.62 | 2.5 |
The Company completed its trenching program on the Evelyn property in March and the current results represent the final assays to be received. A definite highlight of the program is the return four high grade assays, all > 5 g/t Au (see table above) from the El Sahuaro area. The high-grade samples are relatively closely spaced (15 to 60 m spacing) and are located within a domain of previous sampling that contains a generally highly anomalous background Au grade. Previous sampling in the area also returned a grade of 41.0 g/t Au. The current and previously released high-grade samples in the area consist of quartz veins with minor oxidized pyrite and iron oxide minerals. The quartz veins are 10 to 15 cm thick, have a consistent north-northwest strike, and dip moderately to steeply to the east-northeast. The strike length of the veins remains unknown. The vein orientation in the newly mapped trenches is similar to shorter range, NNW trending structures evident in the generally north-northeast trending magnetic pattern in the El Sahuaro area.

In addition to the El Sahuaro results, a single sample taken in the Central Evelyn area returned a value of 2.62 g/t Au and 2.5 g/t Ag. The sample was taken from a previously untrenched target based on an interpreted magnetic lineament. The sample was recovered from a zone of sheared, chlorite altered, and locally silicified andesite. The sample supports the interpretation of the drone magnetic data set and the target will be pursued in future programs.
"The Company is evaluating a model for mineralization, not unlike mineralization at the nearby La Herradura and Noche Buena gold mines, where open pit mining would be supported by a style of mineralization characterized by lower grade mineralization, above a cut off grade of 0.10 g/t Au, that is fracture and alteration controlled and which hosts higher grade quartz dominated veins and veinlets. The distribution, and inferred density, of high-grade veins we are now seeing at the El Sahuaro target is very encouraging. It is also encouraging that our geological team is now reconciling vein and structural orientations with larger scale structures evident in our Drone magnetic dataset," says Ian McGavney, COO of Colibri.

Induced Polarization Program Update
As recently announced, Colibri has retained Geofisica TMC, S.A. de C.V. ("TMC") to complete 3D Induced Polarization ("IP") survey at Evelyn. The survey will focus on the Cerro Rojo and El Sahuaro target areas and will include the intervening area which is characterized by a thick accumulation of alluvium. TMC has confirmed that the work will start today (April 19) and is expected to take approximately 1 month to complete. The IP survey will be integrated with the project exploration dataset which will form the basis for planning the Company's drill planned drill program.
About the Evelyn Gold Project
The Evelyn Gold Project is an Orogenic-type gold target located in the Caborca Gold Belt of northwestern Sonora. The property is located approximately 25 km east of Fresnillo PLC's La Herradura, Mexico's largest open pit gold mine, which produced 482,722 ounces of gold in 2019 at an average grade of 0.8 g/t Au and is approximately 9 km northeast of their Noche Buena mine which produced 127,166 ounces Au at an average grade of 0.55 g/t Au in 2019. The Evelyn property is 100% owned by Colibri and is not subject to any royalty agreements. The Company has completed geological mapping and sampling programs, trenching, a property-wide soil geochemistry, a property-wide Drone magnetic survey, and has completed 5 diamond drill holes.
