NEWS RELEASE - Dieppe, NB., December 19, 2023 - Colibri Resource Corporation (TSX.V:CBI) (OTC:CRUCF) ("Colibri" or the "Company") is very pleased to announce that its recently completed drilling program has resulted in the discovery of a promising new zone of gold mineralization on the Evelyn property at the EP gold project located in the Caborca Gold Belt, NW Sonora. The new area of mineralization has been named West Sahuaro. Drilling highlights of the West Sahuaro includes:
Ian McGavney, President & CEO of Colibri commented: “Our new discovery at the West Sahuaro Zone is the thickest, most continuous, and highest grade gold mineralization intersected to date on the Evelyn property. We are extremely pleased with these results. The grade of mineralization discovered is approaching the reported production and resource grades at mines and development stage projects in the Caborca Gold Belt. The longer intercepts calculated at a 0.1 g/t Au cutoff grade and the occurrence of pervasively anomalous Au indicates that we have moved into a favourable litho-structural setting on the property. Geophysical and surface mapping indicates that the northwesterly structure that West Sahuaro sits on extends at least 2.5 km in length. We will begin building on this success with further exploration drilling in the West Sahuaro area and by leveraging our exhaustive exploration data set to further target areas along this and other identified mineralized structures.”
Recently Completed Drilling Program
Seventeen reverse circulation (“RC”) drill holes totaling 2,200 metres were completed in two target areas; the West Sahuaro (“WS”) target located in the northeastern part of the Evelyn property immediately west of the El Sahuaro target and the Main Zone area located in the central part of the property (Figure 1).
West Sahuaro – (New Discovery Area)
Six holes (764 m) were drilled on 2-3 hole, E-W, sections spaced at approximately 150 m. All holes intersected significant mineralization consisting of longer intersection lengths calculated at a 0.1 g/t Au cutoff grade and which include higher grade intervals (see table of significant intercepts). Utilizing the 0.1 g/t cutoff grade intervals, the ESW mineralization is consistently interpreted as 3 shallowly east dipping lenses (Figures 2a and 2b below) with a projected to surface extent of approximately 200 m x 300 m. Intersected mineralization is open in all directions, up and down dip and along strike. Four of the six holes ended in mineralization > 0.1 g/t Au. Au assays have been completed on 600 samples and only 7 of these samples returned assays below detection limit.

Table 1: West El Sahuaro Significant Drill Assays
The West Sahuaro drill target was prioritized based on a coherent Au in soil anomaly that trends north northwesterly over approximately 500 m length. The Au soil anomaly is spatially associated with a similarly oriented north northwesterly structure that has been derived from geological mapping as well as IP resistivity interpretation. The interpretation of said steep resistivity gradient extends through the IP data sets to the southeast of Evelyn and onto the Plomo property over a total distance of approximately 2.5 km (Figure 3). The trend of the resistivity gradient, when projected approximately 1 km further to the southeast, intersects Banco de Oro, a historical small scale Au mine which is a prioritized target for the Company. The Company is evaluating the significance of the north-northwest trending structure and West Sahuaro mineralization spatial association and anticipates further testing of this setting across the Evelyn and Plomo properties.
Main Zone Area Drilling
A total of 1,436 m was drilled at the Main Zone. Three separate targets were tested (see figure 4):

About Main Zone
The Main Zone is the most advanced target on the Evelyn property. It is interpreted as a series of north-northeasterly striking and moderately east dipping lenses occurring over an approximate strike length of 250 m and previously drilled to a vertical depth of approximately 120 m. Mineralization exposed on surface and in historical mine workings consists of a north-northeast striking and moderately easterly dipping quartz vein that is discontinuously exposed over a strike length of approximately 120 m. The quartz vein pinches and swells along the strike length on surface reaching a maximum exposed thickness of approximately 1.5 m. Grab samples from surface exposures of the vein have returned assay values of 43.9 g/t Au and 40.1 g/t Au. Previous drilling has intersected similarly high-grade mineralization and includes 12.19 g/t Au over an intersection length of 3 m. Mineralization in both the hangingwall and footwall of the Main Zone vein includes multiple quartz vein intersections and low to locally moderate grade Au assay values in chlorite-carbonate-pyrite altered host rocks. Longer mineralized intercepts of veined and altered host rock comprising the easterly dipping lenses at the Main Zone include:
South of the exposed Main Zone vein, the north-northeast trending structure is interpreted to extend under colluvium cover. To explore the southern extension of the Main Zone, the Company completed a Soil Gas Hydrocarbon (“SGH”) survey which resulted in a well-defined anomaly.
About the EP Project and Next Steps
The EP Gold Project is located within the Caborca Gold Belt (“CGB”) of northwestern Sonora and is comprised of the Evelyn and the Plomo properties covering a total of 4,766 hectares (“Ha”). The northwest trending CGB is approximately 500 km in length and is characterized by a number of orogenic-type gold deposits, prospects, and occurrences including the > 15 million ounce La Herradura Mine, located 25 km west of EP, the > 2-million-ounce Noche Buena Mine located approximately 8 km southwest of EP, and the past producing Soledad-Dipolos Mine (> 3 Moz Au) located approximately 32 km to the northwest of EP (see figure 5).
The Evelyn property was acquired by the Company in 2012 and the acquisition of the Plomo property was completed in March of 2023. On the Evelyn property, Colibri has completed comprehensive surface exploration including soil sampling, geological mapping and outcrop sampling, an airborne magnetic survey, and a property wide induced polarization survey. Since February 2020, Colibri has drilled a total of 12,333 metres (total of reverse circulation and core drilling) and is advancing mineralized zones at the Main Zone, El Sahuaro, and the newly discovered West Sahuaro. On the Plomo property, the Company has compiled historical exploration data and has completed its first exploration program which included geological mapping and outcrop sampling at selected target areas on the property.
The Company is continuing to advance its EP project-wide interpretation and exploration model and has identified 14 target areas (see figure 6) with recent and historical work that includes high grade grab samples from outcrop, high grade grab and channel samples from historical mine working, and drill intercepts that are both locally high grade and are consistent with grades being mined in the Caborca Gold Belt. Current work includes interpretation and inclusion of the drill results reported here and the prioritization of future drill targets. To support this work, the Company will complete an airborne (drone) magnetic survey over a selected part of the Plomo property in January 2024 and will be completing detailed geological mapping on selected targets and areas of the EP Project.
