Colibri Option Partner Begins Additional Phase III Drilling on Priority Targets at Pilar Gold & Silver Project in Sonora
Colibri Option Partner Begins Additional
Phase III Drilling on Priority Targets at Pilar
Gold & Silver Project in Sonora
Dieppe, New Brunswick--(Newsfile Corp. - June 22, 2022) - Colibri Resource Corporation (TSXV: CBI)
("Colibri" or the "Company") is pleased to report that today its option partner Tocvan Ventures (CSE:
TOC) has announced that it has initiated additional Phase III drilling at the Company's Pilar Gold & Silver
Project in Sonora, Mexico.
Tocvan is in year 3 of a 5-year agreement to earn an initial 51% of Colibri's Pilar Gold & Silver Project.
For full details of Colibri's agreement with Tocvan please see the Company's news release dated
September 24th, 2019
.
Tocvan Reports:
(June 22
nd
, 2022)
As a continuation of Phase III, drilling will focus on priority exploration targets across the property.
Targeting parallel trends and trend extensions will remain a focus as the Company looks to rapidly define
the extent of mineralization at Pilar. Recent reconnaissance drilling in a 200-meter gap between the
Main Zone and 4-T Trend was successful in defining a new parallel trend (JES-22-63 returned 54.9-
meters at 0.3 g/t Au and 5 g/t Ag from 6.1-meters depth). Another 200-meters to the east, surface
exploration returned chip samples of 6.6 g/t Au and 433 g/t Ag defining an untested extension of the 4-T
Trend, both of these targets will be tested during this stage of drilling.
"We are excited for this next stage of drilling at Pilar, as we feel the potential to expand the known
areas of mineralization is very significant,"
commented Brodie Sutherland, CEO. "
All of these targets
have compelling surface geochemistry that warrant further evaluation. Information collected here will
be instrumental to the next steps of development as we look to utilize substantial funding to fully
unlock the potential of Pilar."

Including
13.7m at 0.6 g/t Au and 13 g/t Ag, from 6.1m

Near-Term Catalysts at Pilar
Ongoing Exploration and Expansion Drilling
Ongoing Metallurgical Studies
Advancing Towards:
Maiden Resource Estimate
Bulk Test Mine Determination
Update on Metallurgical Studies
Metallurgical analysis of select trench samples are still underway, the Company expects reports to be
available soon. The Company's expectation is to have Pilar match other regional analogs that show a
range of gold recovery between 67.6% (La Colorada, Argonaut Gold. 2022 Technical Report) and 75%
(Santana, Minera Alamos. April 7, 2022 News Release). Continuous metallurgical work will be required
to understand best methods to recover gold and silver across different domains on the project.
About the Pilar Property
The Pilar Gold-Silver property is interpreted as a structurally controlled low-sulphidation epithermal
project hosted in andesite rocks. Three zones of mineralization have been identified in the north-west
part of the property from historic surface work and drilling and are referred to as the Main Zone, North Hill
and 4-Trench. Structural features and zones of mineralization within the structures follow an overall NW-
SE trend of mineralization. Over 20,700 m of drilling have been completed to date. Significant results are
highlighted below:
2021 Phase II RC Drilling Highlights include (
all lengths are drilled thicknesses

Quality Assurance / Quality Control
RC chips and core samples were shipped for sample preparation to ALS Limited in Hermosillo, Sonora,
Mexico and for analysis at the ALS laboratory in North Vancouver. The ALS Hermosillo and North
Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. Gold was analyzed using 50-gram
nominal weight fire assay with atomic absorption spectroscopy finish. Over limits for gold (>10 g/t), were
analyzed using fire assay with a gravimetric finish. Silver and other elements were analyzed using a four-
acid digestion with an ICP finish. Over limit analyses for silver (>100 g/t) were re-assayed using an ore-
grade four-acid digestion with ICP-AES finish. Control samples comprising certified reference samples
and blank samples were systematically inserted into the sample stream and analyzed as part of the
Company's robust quality assurance / quality control protocol.
