Metres - Returning 7.2 g/t Gold and 80 g/t
Silver over 2.6 Meters Within 46.9 Meters of
0.5 g/t Gold at the El Pilar Gold-Silver Project
Dieppe, New Brunswick--(Newsfile Corp. - April 16, 2025) - Colibri Resource Corporation (TSXV: CBI)
("Colibri" or the "Company") is pleased to share the assay results from the last three holes drilled in its
recent 10-hole diamond drilling program (1,167.5 metres) at the advanced exploration stage project
El
Pilar Gold & Silver Project
in Sonora Mexico. Colibri holds a 49% interest in the El Pilar along side its
51% partner Tocvan Ventures, which was the operator of this recent drill program. Colibri is relying on
the accuracy of Tocvan's news release dated April 16
th
, 2025.
Colibri President & CEO Ian McGavney commented:
"We are pleased with overall results from this
recent diamond drilling program. The footprint of the gold & silver mineralization at Pilar has
been expanded and opens the doors for potential future drilling along the Main Zone trend as
well as the less understood 4T and North Hill trends. Our attention will now be focussed on
working with our partner to advance a maiden estimate as well as finalizing plans and permitting
for our upcoming up to 50,000 tonne test mine/bulk sample."

Highlights:
Step-out Drilling 70 meters South, Extends Main Zone
High-Grade Vein Returns 2.6 meters of 7.2 g/t Au and 80 g/t Ag
Duplicate Sample Analysis of High-Grade Vein returns
18 g/t Au over 1.1 meters
Within Broader zone
averaging 0.5 g/t Au over 46.9 meters, starting from 54.5 meters
depth
Remains Open and Untested to the South
April 16, 2025 /
Tocvan Ventures Corp. (the "
Company
"), is pleased to announce the remaining results
from core drilling at the Gran Pilar Gold Silver Project in mine-friendly Sonora, Mexico. Ten core
drillholes totaling 1,167.5 meters were completed earlier this year within the majority owned (51%) Main
Zone held in partnership with Colibri Resource Corp. Today's results are highlighted by
7.2 g/t Au and
80 g/t Ag over 2.6 meters
, within a mineralized zone that averages
0.5 g/t Au over 46.9 meters
starting from 54.5 meters downhole
(drillhole JES-25-112). Drill hole JES-25-112 is located 70
meters south of past drill hole JES-22-62, which returned 108.9 meters of 0.8 g/t Au (see April 26, 2022
News Release). Mineralization is hosted in a stockwork of quartz veining, with high grade zones
associated with shear zones with quartz and iron oxides filling fractures. JES-25-112 marks the southern
most successful hit of significant mineralization to date, the trend remains open to the south. A core
duplicate sample through the high-grade zone returned
18 g/t Au over 1.1 meters
, the original sample
returned 4.4 g/t Au. The variance has been noted as a product of coarse gold in the system. The
Company is evaluating additional studies to determine the impact of high-grade variance on resource
estimation. Hole JES-25-111, located 450 meters northeast of the Main Zone, within the 4-T Trend
returned an anomalous zone of gold and silver that included 0.7 meters of 0.8 g/t Au and 24 g/t Ag. Hole
JES-25-110 located 300 meters from the Main Zone, within the North Hill Trend returned an anomalous
zone that includes 7.8 meters of 0.1 g/t Au. Intervals reported are drilled widths, true estimated widths
are not known at this time.
"Step-out drilling south of the Main Zone has extended the high-grade corridor where we
previously thought mineralization stopped." commented, CEO Brodie Sutherland. "This has
opened up the opportunity to further extend mineralization to the south adding near surface
resource potential. We have been very pleased with the success rate of the core program,
adding key geological information for resource modelling whilst enhancing our understanding
of high-grade zones and the true size potential of mineralization..."

Based on management's strong belief in the project's potential, the Company is outlining a permitting
and operations strategy for a pilot facility at Pilar. The facility would underpin a robust test mine scenario
with aims to process up to 50,000 tonnes of material. Timelines and budget are being prepared with the
aim of moving forward with the development early in 2025. With gold prices hitting all-time highs, the
Company believes the onsite test mine will provide key economic parameters and showcase the mineral
potential of the area. In 2023, the Company completed an offsite bulk sample that produced important
data showcasing the potential to recover both gold and silver through a variety of methods including
heap leach, gravity and agitated leach (see August 22, 2023, news release for more details).
Quality Assurance / Quality Control
Rock and Drill 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.
