Dieppe, New Brunswick–(Newsfile Corp. – February 12, 2025) – Colibri Resource Corporation (TSXV: CBI) (“Colibri” or the “Company”) is pleased to share that a total of 1,122 meters has been drilled in 10 diamond drill holes at its El Pilar Gold & Silver Project in Sonora Mexico. Colibri holds 49% interest of the El Pilar along side its partner Tocvan Ventures, which holds a 51% ownership in this advanced stage exploration project.
Highlights:
The core program was designed and managed by Tocvan with the aim to infill and step out on known mineralization corridors. The information collected will assist in building a robust geological model set to go into a maiden resource estimate and ultimately a Preliminary Economic Assessment for Pilar’s Main Zone. Samples for the first three drillholes (JES-25-103 to JES-25-105) have been delivered to the local ALS Prep Laboratory in Hermosillo, Sonora.
In a news release dated February 12, 2025, Brodie Sutherland, the President & CEO of Tocvan Ventures reported the following:
“…The majority of past drilling has been RC, core drilling provides us with key information on the complex structural nature hosting mineralization that will drive future resource expansion. It is clear the host rock has undergone substantial multi-phase preparation making it an excellent target. We look forward to the results.”
Tocvan has also reported that core reviewed from this drill program displays indications of key lithologies and structures known to host and control gold & silver mineralization at Pilar. A summary of these mineralization types is summarized below in Plate 1. The Company cautions these are visual indications; assay results are pending to verify the grade of mineralization and width.
Plate 1. Different alteration and lithology styles related to mineralization at Pilar as seen in the recent core program. A. Intense hematite flooding of andesite host rock with later silicification, JES-25-104, 88 m depth. B. Silicified breccia with intense silicification, moderate epidote-chlorite alteration and late hematite vein stockwork, JES-25-104, 90m depth. C. Wide intensely oxidized fault zone with white quartz veining, JES-25-103, 23m depth. D. Malachite with hematite in highly fractured and oxidized host rock, JES-25-103, 27m depth. E. Silicified breccia with intense chlorite and pyrite and minor chalcopyrite, JES-25-107, 55m depth. F. Intense fractured silicified breccia with intense hematite and late calcite veins, JES-25-105, 85m depth. The Company cautions these are visual indications; assay results are pending to verify the grade of mineralization and width.

Pilar Pilot Mine Facility / Large Tonnage Bulk Sample
Based on management’s strong belief in the project’s potential to be a near term mine, the JV companies are presently outlining a permitting and operations strategy to build a pilot facility at Pilar. The facility will support a robust test mine scenario with an aim to process up to 50,000 tonnes of material. Timelines and budgets are being prepared with the goal of moving forward on its development in very near term to potentially take advantage of the historically high gold prices.
In 2023, Tocvan completed a smaller offsite bulk sample at Pilar which showcased the potential to recover both gold and silver through a variety of methods including heap leach, gravity and agitated leach. Datasets recovered from 2023 program will serve as a guide for this upcoming one.
About the Pilar Property
The Pilar gold-silver property has returned some of the region’s best drill results. Coupled with encouraging gold and silver recovery results from metallurgical test work, Pilar is primed to be a potential near-term producer. The project is interpreted as a structurally controlled low-sulphidation epithermal system hosted in andesite rock. Initially, three primary zones of mineralization were identified on the original property from historic surface work and drilling, and are referred to as the Main zone, North Hill and 4-T. Each trend remains open to the southeast and north, and new parallel zones have been discovered. Structural features and zones of mineralization within the structures follow an overall northwest-southeast trend of mineralization. Mineralization extends along a 1.2-kilometre…
