Colibri Partner Engages Environmental Report
for Drill Permit and Updates Historical
Sampling from Diamante Concessions
Dieppe, New Brunswick--(Newsfile Corp. - January 25, 2022) - Colibri Resource Corporation (TSXV:
CBI) ("Colibri" or the "Company") is pleased report that its partner Silver Spruce Resources ("Silver
Spruce") has released an update about the status of exploration at the Diamante Gold & Silver Project in
Sonora Mexico.
Silver Spruce is currently earning up to 50% of the Diamante project in conjunction with Colibri as a
result of a deal negotiated with a private vendor and announced in January 2021. Please see Colibri
news release dated
April 29
th
, 2021
for full details of the agreement in place with Silver Spruce.
Silver Spruce Reports:
Silver Spruce Resources Inc. ("Silver Spruce" or the "Company") announces that the Company has
initiated its Informe Preventivo for application to the Mexican government environmental authority
SEMARNAT for the Diamante drilling permit.
Silver Spruce engaged Green & Ceo, Asesorío
Profesional y Securidad en Ambiente, of Hermosillo, Sonora to manage the environmental permitting
process.
The SEMARNAT permit is expected within four to six weeks of submission.
The Company also is pleased to provide high-grade results from additional historical rock sampling at
several known targets with artisanal workings.
Recent literature research identified reports with maps,
field sampling sections and assays for seventy-seven (77) previously unreleased samples with precious
and base metal values reporting up to 25.69 g/t Au, 1,360 g/t Ag, 18.2% Pb, 33.5% Zn and 1.47% Cu.
The surface and U/G channel samples (to 2.5 metres) were collected from Diamante 1, the northern
concession, at the La Prieta, Aguaje, El Chon, El Chon Oeste, El Chon Sur, Hacia del Oeste, La Olla,
Lupita, Pillado, Pillado Sur and Pillado Grande targets (Figure 1).
The highest-grade individual sample
was collected from a 15cm vein in the La Prieta workings (25.69 g/t Au, 1,265 g/t Ag, 18.2% Pb, 23.0%
Zn and 1.47% Cu).
The Diamante gold-silver (Au-Ag) project ("Diamante" or the Property") is a drill-ready precious metal
property located 5 km northwest of the town of Tepoca, and 165 km southeast of the capital city of
Hermosillo, eastern Sonora, Mexico (Figure 2).
Diamante offers strong precious metal tenor with a polymetallic endowment and contains multiple quality
targets, limited artisanal mining and small-scale production, of particular significance for our exploration
moving forward, no records of drilling on either property.
Mr. Davison - VP Exploration stated, "The recent desktop research in Hermosillo contributes significantly
to the project's geological and assay database.
This work confirms additional vein samples with
excellent polymetallic grade of the mineralization ahead of the target mapping program.
The upcoming
geological work will focus on several priority targets documenting detailed lithologies, mineralization,
structural measurements and verification of sampling coordinates with a view to optimization of the
proposed drill target depths and orientations. Additionally, the areas of alteration reported using
hyperspectral imaging require authentication by ground exploration and hand-held spectral data as part
of the drill target definition."

Diamante includes twelve known occurrences at La Prieta, El Aguaje, El Chon, El Pillado, La Olla, La
Cruz and El Caso, Mezquite Raizudo, El Puerto, El Cumbro, Calton and the Southern Anomaly
(Anomalía Sur).
Sampling highlights from these areas of interest, some with artisanal mining, have reported significant
precious and base metals in samples collected from historical mine dumps, small-scale processing slag
and assays from vein and stockwork-style mineralization.
Based on the distribution of the overall sampling (n=354), several newly renamed targets are
designated, and the Diamante concessions overall comprises eighteen mineralized areas with seven
under consideration for the Phase 1 drilling.
These include La Prieta, El Cumbro, Mezquite Raizudo, El
Chon, La Olla, Calton and Pillado.
Disseminated and stockwork mineralization at Anomalía Sur and El
Puerto offer bulk low-grade targets.
Figures 3 and 4 illustrate the La Prieta and El Chon drilling vein target areas with precious metal values
by class, and artisanal pits and workings.
The latter follow projected surface exposures of vein
mineralization.

Project Geology
The Property is located within the west-central portion of the Sierra Madre Occidental Volcanic Complex
within the prominent northwest-trending "Sonora Gold Belt" of northern Mexico and parallel to the well-
known, precious metals-rich Mojave-Sonora Megashear.
Exploration has identified geological features of epithermal low to intermediate sulphidation Ag-Au (Pb-
Zn), high sulphidation Au-Cu, and potential transition to porphyry style Au-Cu.
Precious and base metal
polymetallic mineralization occurs as disseminated, stockwork and vein styles accompanied phyllic,
argillic, advanced argillic and propylitic zones, with near-surface overprinting by weathering with iron
oxide and oxyhydroxide staining, jarosite and relict vuggy silica.
New TLALI algorithm maps for the LANDSAT 8 OLI and LANDSAT/ASTER data confirmed the spectral
response for silicification and argillic alteration, including generic clay, alunite, pyrophyllite, kaolinite and
silica coincident with known artisanal vein workings and disseminated gold targets.

Mineralization is reported visually as pyrite, arsenopyrite, chalcopyrite, sphalerite, argentiferous galena,
argentite, hematite and probable metal oxides, carbonates and sulphates, including copper carbonate
(malachite), copper sulphates and plumbojarosite.
Structural lineaments with ENE, NE and NW orientations identified in the historical exploration
correspond to known vein systems.
Branching and oblique vein sets to the N-S direction were noted
from the ENE veins.
Project Background
Silver Spruce can acquire up to 50% interest in four Diamante concessions, with a cumulative land
position of 1,057 hectares, from Colibri and its wholly-owned Mexican subsidiary, Yaque Minerales SA
de CV ("Yaque"). The nearby large operating mines include Alamos Gold's Los Mulatos gold mine and
Agnico Eagle's La India gold mine, Agnico's Pinos Altos mine and Argonaut's La Colorada Mine.
The Property is very well situated in terms of logistics for exploration and twelve to fifteen kilometres west
and northwest of the Nicho deposit currently under mine development by Minera Alamos.
The Property is
easily accessible from Mexican Highway #16 which transects Diamante 1 and on ranch trails and dry
river beds to Diamante 2.
High voltage power lines are positioned along Highway #16.
Geochemical Analysis, Quality Assurance and Quality Control
All metal values disclosed herein by historical operators (Pan American Silver, Minera Teocuitla) are
reported from grab and chip samples which may not be representative of the metal grades.
The
Company has reviewed the available historical property reports and copies of assay certificates from
International Plasma Labs Ltd. ("IPL"), later known as Inspectorate Americas, and currently Bureau
Veritas Group, and compared the grades with sampling programs and assays reported by the Vendors
and Silver Spruce.
IPL was an independent commercial laboratory with ISO 9001-2000 certification
during the 2005-20011 period of the historical work.
The Company's Qualified Person believes that the
sampling, analytical protocols and data will withstand scrutiny for inclusion.
