Colibri Resource Corporation Discovers Mineralized Quartz Veins in Sub-Crop at its Evelyn Property, Mexico - Samples as high as 4.81 grams per tonne

DIEPPE, June 3, 2019 -  (TSXV: CBI) Colibri Resource Corp. ("Colibri" or the "Company") is pleased to announce that it has received additional assays from its geological mapping and sampling program on the Evelyn property, in northern Sonora, Mexico.  Results from grab samples include values of 4.81 g/t Au and 4.19 grams per tonne ("g/t") Au from an area not previously mapped or sampled.

Recent and on-going geological mapping and sampling on the Evelyn property has been aimed at following up anomalies from a soil geochemistry survey completed in 2011.  The samples returning 4.81 g/t Au and 4.19 g/t Au were collected from an area comprised of abundant quartz in sub-crop with local iron-oxide staining.  The newly discovered area was located by following up an anomalous soil sample of 0.33 g/t Au and is located approximately 1 km north-northeast of the Main Zone.  The Main Zone consists of a moderately to steeply dipping Au-bearing quartz vein which has been the subject of historical mining.  Recent sampling of the Main Zone vein by Colibri returned grab sample values of up to 43.1 g/t Au (see Colibri news release dated March 26^th, 2019).

In addition to on-going geological mapping and sampling at Evelyn, the Company is planning a property wide, high density, airborne magnetic survey.  The objective of the integrated exploration approach is to determine the structural framework of the property and the setting of known gold mineralization.  Based on the outcome of this phase of exploration, advanced exploration activities being contemplated by the Company include trenching, 3D Induced Polarization surveys, and drilling on selected targets.  The Evelyn property has not been previously drill tested.

About Evelyn

The Evelyn property is located in northern Sonora, within the Caborca Gold Belt ("CGB").  The CGB is hosted by the Sonora megashear, which in turn is part of the regional Mojave-Sonora megashear, which extends from southern California through Arizona and Sonora.  The Caborca Gold Belt hosts the Noche Buena Mine (167,200 ounces Au produced in 2018) which is located approximately 9 km southwest of Evelyn and La Herradura Mine (474,200 ounces Au produced in 2018) which is located approximately 30 km to the west of Evelyn.  Geological mapping completed by Company geologists confirm that the Evelyn property hosts Orogenic-type lode Au mineralization similar to that described for other gold deposits within the CGB.
