Colibri Resumes Exploration and Applies for
Drill Permit at the Evelyn Gold Property,
Northwestern Sonora, Mexico
Dieppe, New Brunswick--(Newsfile Corp. - October 27, 2022) - Colibri Resource Corporation (TSXV:
CBI) (OTC Pink: CRUCF) ("Colibri" or the "Company") is pleased to report that the Company has
resumed exploration at the Evelyn Gold Property.
Company geologists have recently mobilized to the
property and are currently collecting soil samples.
The Company is also pleased to report that on
October 10
th
, applications for drilling and trenching permits at the Evelyn property were submitted to
SEMARNAT (the Mexican government environmental authority). Approvals for this work are expected
shortly.
Upon receipt of the drill permit, the Company intends to complete 2 drill programs. The first program will
be following up on the Company's Phase 1 reverse circulation ("RC") drilling program completed in the
fall/winter of 2021/2022 will include a planned 2,000 metres ("m") in 5 holes designed to test the results
of the Induced Polarization ("IP") Survey completed in 2021.
The primary target is a chargeability
anomaly that underlies the Main Zone, and the program will include testing a chargeability and resistivity
target west of the Main Zone.
The locations of the holes planned to test the IP results are indicated in
Figure 1.
The second drill program is planned to explore under extensive alluvial cover north of the Main Zone and
will comprise drilling a number of short, relatively closely spaced RC holes designed to penetrate the
alluvium and sample the top of bedrock.
The objective of this program is to locate the northern extension
of the Main Zone and to test for the location of other potentially mineralized structures interpreted by the
Company.
The locations of the areas planned for drill testing bedrock covered by alluvium are indicated
in Figure 1.
The soil sampling currently in progress has been designed to test for the southern extension of the Main
Zone structure under an apron of relatively thick colluvium and will consist of a Soil Gas Hydrocarbon
("SGH") program with analyses and interpretation being completed at Activation Laboratories Ltd.
("Actlabs") located in Ancaster, Ontario.
The planned locations of the soil samples being collected are
indicated on Figure 1.
Upon receipt of the permit to excavate trenches, the Company will complete a series of trenches across
the West Sahuaro target. The West Sahuaro target is based on a discrete soil anomaly whose location
and orientation is coincident with a strong resistivity gradient evident in the 2021 IP survey results.

MAIN ZONE EXPLORATION AND PLAN
The Main Zone mineralization occurs as a quartz vein that is discontinuously exposed over a strike length
of approximately 120 m.
The quartz vein pinches and swells along the strike length on surface reaching a
maximum exposed thickness of approximately 1.5 m.
Grab samples from surface exposures of the vein
have returned assay values of 43.9 g/t Au and 40.1 g/t Au.
During Phase 1 RC drilling at Evelyn, the
Company completed a total of 872 m in 6 holes at the Main Zone.
Four of the holes were directed at the
Main Zone vein and two of the holes were drilled in the footwall of the Main Zone vein in a direction away
from the Main Zone vein.
Highlights of the Main Zone vein drilling include 12.19 g/t Au over an
intersection length of 3 m which includes an assay of 30 g/t Au over 1 m in hole EVE21-027 and an
intersection of 3.28 g/t Au over an intersection length of 2 m in hole EVE22-029.
Hole EVE22-030 was
drilled in the footwall of the Main Zone vein and intersected 87 m at an average grade of 0.127 g/t Au
including 8 m at an average grade of 0.336 g/t Au.
Planned to reach a target depth of 250 metres, Hole
EVE22-030 was lost due to drilling conditions at a depth of 129 m.
Hole EVE22-042 was drilled beside
EVE22-030 as an attempt to extend the hole to the target depth of 250 m.
The hole intersected multiple
zones of mineralization including 0.165 g/t Au over an intersection length of 86 m which included an
intersection of 0.551 g/t Au over 10 m.
EVE22-042 did not reach target depth as it was also abandoned
due to drilling conditions at 177 m.
An assay of 0.374 g/t Au over an interval of 1 m was returned from a
sample at 174 m depth: 4 m from the end of the hole.
Complete Phase 1 drilling results from the Main
Zone are contained in the table below.

Table 1 – Drill Highlights from Phase 1 Drilling at Main Zone Area
The Main Zone mineralization, including mineralization intersected in holes EVE22-030 and EVE22-042
directly overlies a discrete Induced Polarization ("IP") chargeability anomaly (Figures 1 and 2).
The
chargeability anomaly is coincident with an apparent resistivity anomaly and is most strongly developed
at a depth greater than 200 m (Figure 2).
The exploration model relates Main Zone mineralization,
exposed on surface and intersected in Phase 1 drilling, to an altered rock body with elevated
disseminated sulphide at depth which is controlled by the intersection of the northeast and northwest
structures. Phase 2 drilling is planned in the near term to test this model to a depth of at least 500
metres. (Figure 2).
In addition, 2 holes are planned to test a weaker IP anomaly on the flank of a resistive
high west of the Main Zone.

WEST EL SAHUARO TARGET EXPLORATION AND PLAN
El Sahuaro Zone is located in the northeastern part of the property and is characterized by north-
northeast trending magnetic anomalies. Detailed structural mapping in the northeast part of the property
indicates a dominant north-northwestern strike and easterly dip to foliation and veins.
The structural
orientations observed are consistent with north-northwest trending structures interpreted from magnetic
intensity contrasts and an apparent dislocation and offset of the north-northeastern magnetic trend.
The
El Sahuaro area is underlain by Jurassic rhyolite and andesite and by Proterozoic (?) metasedimentary
rocks.
All holes drilled at El Sahuaro have intersected Au mineralization.
Highlights of Phase 1 drilling at
El Sahuaro include: (also see Figure 3 below)
EVE21-025
- 0.172 g/t Au over an intersection length of 22 m.
EVE21-018
- 0.103 g.t Au over an intersection length of 25 m.
EVE21-019
- 2.36 g/t Au over an intersection length of 15 m.
EVE22-043
- 0.92 g/t Au over an intersection length of 3 m.
EVE22-044
- 0.627 g/t Au over an intersection length 6 m.
EVE22-046
- 1.943 g/t Au over an intersection length of 2 m and 0.51 g/t Au over an intersection length
of 4 m.
West of El Sahuaro zone, a sharp north-northwest trending gradient in apparent resistivity (Figure 3) is
interpreted as a fault zone that separates dominantly rhyolite to the southwest with a mixed succession of
rhyolite and andesite with Proterozoic metamorphic rocks to the northeast.
To further explore the interpretation of apparent resistivity, the Company completed in-fill soil sampling of
the historical soil geochemistry survey which resulted in a coherent soil anomaly over an approximately
500 m length and 200 m width with a north-northwest trend: parallel to the resistivity gradient (Figure 3).
Anomalous soil samples in the anomaly area are interpreted to be locally derived and include an assay
of 1.5 g/t Au.
The model being explored by the Company relates mineralization intersected in Phase 1 drilling at El
Sahuaro, and the Au soil anomaly, to a major controlling structure indicated by the apparent resistivity
gradient.
Trenches currently being permitted will be excavated over the soil anomaly with the objective of
advancing he target to the drill stage.

ABOUT SGH
SGH is a deep penetrating geochemical exploration method that involves the analysis of surficial
samples from over potential (buried) mineral or petroleum targets. The analysis involves the testing for
162 hydrocarbon compounds in the C5-C17 carbon series range applicable to a wide variety of sample
types.
Samples are collected in the target area in a systematic manner generally at sample stations
spaced at 25 m along 100 m spaced lines. Actlabs has developed an in-depth understanding of the
unique SGH signatures associated with different commodity targets. Using a forensic approach based
on scientific research, orientation surveys over known (buried) mineralization, and the results of
exploration projects, Actlabs has developed commodity target signatures, or templates, for identification
of the expected analytical results exhibited by each class of SGH compounds.
EVELYN GEOLOGY AND EXPLORATION
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 kilometres ("km") east of La Herradura,
Mexico's largest open pit gold mine, which produced 425,288 ounces of gold in 2020 at an average
grade of 0.77 grams per tonnes ("g/t") Au and is also approximately 9 km northeast of the Noche Buena
mine which produced 87,988 ounces Au at an average grade of 0.52 g/t Au in 2020.
The setting and
style of mineralization at Evelyn is similar to that reported from La Herradura and Noche Buena.
Higher
grade mineralization on the Evelyn property consists of quartz veins and veinlets, ranging from 2 – 3
centimeters up to 1.5 m hosted by fault and fracture zones with minor oxidized pyrite, iron oxide, copper
bearing oxide and carbonate minerals, and locally minor to trace amounts of galena, chalcopyrite, and
sphalerite.
Alteration of the host rocks includes iron bearing carbonate minerals, quartz, sericite, and
chlorite.
Lower grade mineralization is associated with altered volcanic rocks containing minor amounts
of oxidized sulfide.
Mineralization is hosted dominantly by Jurassic volcanic rocks consisting of andesite
and rhyolite.
The exploration model being developed and tested by the Company relates the mineralization consisting
of higher-grade veins and veinlets hosted by altered and sulphide bearing lower grade metamorphic and
volcanic rocks, to north-northeast trending stratigraphy and layer-parallel fault zones and southeast
striking, moderately southwest dipping fault zones.
