Colibri Option Partner Drills 116.9-Meters of 1.2 g/t Au and 7 g/t Ag, Including 10.2-Meters of 12 g/t Au and 23 g/t Ag at Pilar
Dieppe, April 14, 2022 - Colibri Resource Corp. (TSXV: CBI) ("Colibri" or the "Company") is pleased to report that its option partner Tocvan Ventures has announced drilling results from the Company's Pilar Gold & Silver Project in Sonora, Mexico. Results for drill hole JES-22-59 are provided in this release. The hole is a diamond core twin of RC drill hole JES-20-32 which returned 94.6-meters at 1.6 g/t Au (see Figure 1).
A total of 1,562 meters of Phase III drilling has been completed in nine drill holes providing key information across the Main Zone and 4-T Trend. Results for five drill holes are pending.
Tocvan is in year 3 of a 5-year agreement to earn an initial 51% of Colibri's Pilar Gold & Silver Project. Colibri currently owns in excess of one million shares of Tocvan and is scheduled to receive additional compensation shares and cash annually from the purchaser during the remainder of the option period. For full details of Colibri's agreement with Tocvan please see the Company's news release dated September 24th, 2019.

Drill Highlights
JES-22-59 (Core)
- 116.9m at 1.2 g/t Au and 7 g/t Ag
- Including 48.1m at 2.8 g/t Au and 9 g/t Ag
- Including 10.2m at 12.0 g/t Au and 23 g/t Ag
- Including 4.2m at 28.3 g/t Au and 49 g/t Ag
"Once again core drilling has confirmed the significant grade and distribution of gold-silver mineralization at Pilar," commented Brodie Sutherland, CEO. "This further validates the strength of the shallow mineralized system at Pilar, especially in regard to the significant high-grade mineralization adjacent to controlling structures. We look forward to reviewing the remaining results that test the extension of these controlling faults to the southeast."
Discussion of Significant Results
As part of the Phase III program, nine drill holes have been completed totalling over 1,562 meters (Figure 1). Drilling looked to expand the Main Zone through 25, 50 and 100-meter step-outs to the southeast in a gap zone that has seen little drilling focused on the main trend between hole JES-20-32 (94.6m at 1.6 g/t Au) and hole JES-21-50 (39.7m at 0.96 g/t Au). Drilling also covered the 4-T Trend testing below trench T-21-3, which returned 19.5 meters at 0.61 g/t Au.
Confirmation of host rock and structure through the Main Zone was completed with core drilling, targeting key areas where past RC drilling has intersected significant gold-silver mineralization. Drill hole JES-22-59 was successful in intersecting a significant zone of oxide gold with broad mineralization in a silicified brecciated andesite host (116.9 meters of 1.2 g/t Au, including 48.1 meters of 2.8 g/t Au and 9 g/t Ag). The intersection included a high-grade fault bounded zone grading 12 g/t Au and 23 g/t Ag over 10.2 meters. This broad interval correlates with mineralization seen in RC hole JES-20-32, which returned 94.6 meters at 1.6 g/t Au, including 9.2 meters at 10.8 g/t Au and 38 g/t Ag. The high-grade controlling structures indicate a high probability of continuation to the southeast, where pending drill results are located along trend.

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:

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.
