Colibri and Partner – Expands Main Zone by 70 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

April 16, 2025

NEWS RELEASE - Dieppe, NB., March 26th, 2025 - Colibri Resource Corporation (TSX.V:CBI) (OTC:CRUCF) ("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 16th, 2025.

 

“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.” commented, Colibri President & CEO Ian McGavney


Tocvan - News Release – April 16th, 2025


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.

NEWS RELEASE - Dieppe, NB., May 14th, 2025 - Colibri Resource Corporation (TSX.V:CBI) (OTC:CRUCF) ("Colibri" or the "Company") iwishes to announce a series of strategic corporate developments aimed at strengthening its asset base and capital structure. These include: Increasing its effective ownership of the Diamante Gold-Silver Project in Sonora, Mexico to 60%; Entering an agreement to acquire its joint venture partner's remaining interest in the project; Monetizing a non-core asset through the sale of its 50% interest in the Jackie Project; and Implementing a share consolidation to position the Company for improved capital markets access and long-term growth. These actions align with Colibri’s sharpened focus on advancing its two most advanced exploration assets. The Company is collaborating with Tocvan Ventures on the potential future development of the Pilar Gold & Silver Project, where drilling, bulk sampling and trenching suggest near-term production potential. In parallel, Colibri is preparing for further advanced exploration activity at its 100%-owned EP Gold Project, located in a multi-million-ounce gold corridor called the Caborca Gold Belt that hosts Mexico’s largest producing gold mine owned by Fresnillo Plc called La Herradura (25km west of EP). The La Herradura, which has been operating since 1994, produced 367,000 ounces of gold in 2024 and has 7.4 milllion ounces of gold remaining in reserves at the end of 2024 (source: Fresnillo Plc - 2024 Annual Report). Colibri geologists believe that EP shares key geological characteristics with nearby gold deposits, including structure, lithology, and geochemistry—underscoring its discovery potential.
