Dieppe, New Brunswick--(Newsfile Corp. - June 20, 2023) - Colibri Resource Corporation (TSXV: CBI)
(OTC Pink: CRUCF) ("Colibri" or the "Company") is very pleased to report the results of geological
mapping and outcrop sampling at the Pavo Real target on the Plomo property, EP Gold Project,
Caborca Gold Belt ("CGB"), northwestern Sonora.
Results have confirmed and expanded the footprint of
gold ("Au") in tourmaline altered diorite at Pavo Real and include a high of 9.48 grams per tonne ("g/t")
Au.
Ron Goguen, President & CEO of Colibri commented,
"We are very encouraged by the results of
our inaugural exploration work program on the Plomo property, which we acquired in March.
This work represents the first steps in the evaluation of Plomo's large and highly prospective
land position within the EP Gold Project. Colibri will continue to aggressively advance towards
a maiden drill program at Plomo".
PAVO REAL HISTORY & RESULTS
Historical work at the Pavo Real target documents widespread tourmaline alteration including tourmaline
in NW trending structures reported to be traced over a 600 m strike length and containing anomalous
gold values including 5.82 g/t Au.
Due diligence reconnaissance field work, conducted earlier in year,
confirmed the presence of tourmaline-quartz alteration (commonly forming overprinting stock work and
breccia textures) and sampling confirmed the presence of Au with several grab samples greater than 1
g/t Au and a high-grade grab sample of 9.94 g/t Au.
A selected area at Pavo Real, approximately ½ km x ½ km, was mapped and 90 grab samples were
collected for Au analyses (see Map 1).
Au was detected in all but 11 of the samples, 38 of the samples
returned values greater than 0.1 g/t Au, 13 samples returned values greater than 1.0 g/t Au with the
highest grade sample being 9.84 g/t Au.
Mineralized samples (> 0.1 g/t Au) are characterized by quartz-
tourmaline breccia matrix and stockwork overprinting a quartz, sericite, tourmaline, pyrite (Fe-oxide)
altered felsic host rock.
The higher-grade samples also commonly include veinlets mapped as jasperoid
which in thin section was determined to be a very fine grained assemblage of limonite and hematite and
interpreted to possibly be derived from a primary Fe-carbonate bearing vein assemblage.
The
mineralized tourmaline bearing breccia and stock work samples are massive to strongly foliated where
foliation consistently has a north-northwest strike and moderate northeast dip.
Northwest and northeast
trending structures and associated apparent grade directional trends are evident on the Plomo property
(as well as Evelyn).
These structural orientations are important in the regional geological evolution and
control the occurrence of major gold deposits in the Caborca Gold Belt.

EP PROJECT NEXT STEPS
The Company continues to evaluate both the Evelyn and Plomo properties of the EP Gold Project with
the objective of advancing prospects and prioritizing drill targets.
The Company will continue to evaluate
mineralized domains at the Pavo Real target, as indicated by mapping and sampling to date, and
anticipates continued exploration to include geological mapping as well as trenching with a mechanical
shovel.
Assays are pending from geological mapping and sampling also recently completed at the
Banco de Oro and La Bonancita targets.
On the Evelyn side, the Company is currently planning a RC
drilling program to follow up on positive soil geochemistry results north and south of the Main Zone a well
as west of El Sahuaro
ABOUT PLOMO
The newly acquired Plomo property is contiguous with the Company's Evelyn Property and collectively
they comprise the Company's EP Gold Project covering a total area of 4,766 Ha.
The EP Gold Project is
located in the 500 km long, northwest trending Caborca Gold belt which includes the > 15 million ounce
La Herradura Mine, located 30 km west of Plomo, the > 2-million-ounce Noche Buena Mine located
approximately 8 km southwest of Plomo, and the past producing Soledad-Dipolos Mine (> 3 Moz Au)
located approximately 32 km to the northwest (see attached map 2).
Highlights of the Plomo Property include:
The historical database, totaling 1,853 surface rock samples, includes 524 samples greater than
0.1 grams per tonne ("g/t") Au, 132 samples greater than 1.0 g/t Au, and 15 high grade samples
greater than 10 g/t Au. Surface exploration including prospecting, mapping, and rock sampling
since 2007 has resulted in the identification of 9 target areas on the Plomo property (see Map 3)
Underground sampling completed in the adit at the Banco de Oro prospect in 2008 are reported to
have included 298.0 g/t Au over a chip length of 2.4 metres
The Plomo property has been the subject of only very limited exploration drilling, completed in
2008, with a total of 1,570 meters completed in 10 holes.
Highlights of the drilling are 0.66 g/t Au
over an intersection length of 11.65 metres ("m") and 0.92 g/t Au over an intersection length of 4 m.
The Plomo property has had small scale artisanal mining including pits, adits, and placer mining
dating back to the 18th century.
The first recorded exploration was in 2006 and the property has
been the subject of only episodic exploration since that time.
Mapping completed by Colibri geologists confirmed vein style mineralization consisting of veins,
veinlets, and vein stockworks, altered host rocks that include intense silicification, sericite,
disseminated pyrite, and locally tourmaline bearing stockworks and breccias.
Sampling by Colibri completed during its due diligence evaluation confirmed the historical
distribution of high-grade samples at Plomo and included twenty-five grab samples with values >
1.0 g/t Au, including 6 samples with values > 5 g/t Au. A total of 62 grab samples taken by Colibri
during due diligence sampling returned Au assay values > 0.1 g/t Au.
