Colibri's Option Partner Receives Assay

Results for Phase I Drilling Completed at El

Mezquite Gold & Silver Project, Sonora,

Mexico

Dieppe, New Brunswick--(Newsfile Corp. - September 7, 2021) -

Colibri Resource Corporation (TSXV:

CBI) ("Colibri" or the "Company") is pleased to report that its partner, Silver Spruce Resources Inc.

(TSXV: SSE) has announced that it has received assay results from the first 10 holes completed on the

Phase 1 exploration drilling at El Mezquite Au-Ag property ("El Mezquite" or the "Property").

Nine of the

10 holes reported returned assays or assay intercepts greater that 0.1 grams per tonne ("g/t") Au with a

highlight of 0.83 g/t Au over 3.05 metres ("m") in hole MEZ-21-005.

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.

Silver Spruce has received and reported

assay results from the first 10 holes. The results of the remaining 10 holes are pending.

All samples have

been submitted to the assay laboratory.

A table of assay results greater than 0.10 g/t Au, as provided to

Colibri from Silver Spruce, is reported in table 1.

Greg Davison, VP Exploration and Qualified Person for Silver Spruce comments on the drilling and

assay results as follows: "The first 10 holes were drilled mainly on four collar locations targeting 3D IP

chargeability anomalies and were logged primarily as green to grey-green andesite and mafic dykes

exhibiting surface oxidation and transitional zones, weak propylitic alteration and at depth, abundant

disseminated sulphides and/or magnetite.

Andesite dykes contained elevated magnetite.

Minor rhyolitic

units may be feldspar-quartz intrusive dykes.

Oxidation reached depths of 3 metres to 18.3 metres

above transitional intervals of 3 metres to 24.3 metres.

The sulphide zone andesites were intersected at

overall downhole depths of 13 metres to 36.6 metres and continued through the holes.

Pyrite was the

dominant sulphide species with minor chalcopyrite, sphalerite and possible galena.

Sulphides also

occurred in quartz and quartz-carbonate veinlets with a stockwork-style distribution.

The mineralized

intervals, identified to date, reflect the thickness of the vein and structurally controlled surface showings.

Of importance to the geochemical interpretation, the pathfinder elements (Hg, Cu, Pb, Zn, Sb and As)

often display a well-defined metal halo, up to eighteen (18) metres in apparent thickness downhole,

within and peripheral to the multiple gold and silver-bearing intervals and potentially are indicative of a

significant precious metal mineralizing system."

"We are very pleased that virtually all holes reported contain gold mineralization. We look forward to

the assay results pending, Silver Spruce's complete assessment of the results, and their plans for

continued drilling to explore the

Mezquite Property for a large tonnage gold deposit on the Mezquite,"

said Ron Goguen, President & CEO of Colibri.

Silver Spruce Resources is currently in the 2

nd

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
