Colibri’s Option Partner To Commence Exploration Activities At Pilar Gold & Silver Project In Sonora, Mexico
November 10, 2021
NEWS RELEASE - Dieppe, NB. November 10th, 2021 - Colibri Resource Corporation (CBI-TSXV) ("Colibri" or the "Company") is pleased to announce that its partner Tocvan Ventures Corp. (“Tocvan”) has reported the re-commencement of field operations at the Pilar Au-Ag Project in Sonora, Mexico. Tocvan is in the third year of a five-year option agreement with Colibri to earn an initial 51% ownership of the Pilar Gold-Silver Project. For full details of the agreement see Colibri’s news release dated September 24th, 2019.
“We are very happy to see Tocvan taking the next steps in advancing the Pilar Gold & Silver Project. Colibri, through its 100% owned Evelyn Gold Project (which is currently being drilled) and its partnerships on another four projects which are also being actively explored, anticipates steady news about activity, advancement, and growth for many months to come” says Ron Goguen, President & CEO of Colibri.
Tocvan reports that it intends to further evaluate surface mineralization with trenching and channel sampling followed by a series of column leach studies on representative samples at sites across the Main Zone. In addition, drilling is planned with between 5,000 to 8,000 meters estimated to be completed between now and July, 2022. Drilling will focus on step-out drilling along the Main Zone and the new 4-Trench Trend. Exploration drilling will continue to evaluate target areas along the Triple Vein Zone. Surface exploration work will continue with trenching and sampling along the southeastern extension of the Main Zone.
2021/2022 Operation Plans
- Trenching of Main Zone for bulk sampling and column leach study
- 5,000 to 8,000 meters of drilling
- Drilling to include:
- Step-outs of Main Zone targets
- Step-out and Exploration drilling along 4-Trench trend
- Exploration drilling along Triple Vein Zone
- Surface trenching, sampling, and target evaluation.
Trenching across the near-surface mineralized portions of the Main Zone will be completed for channel sampling and subsequently for bulk sampling. Several bulk sample composites will be collected for detailed column leach study and at a later date drill holes will be completed across the Main Zone to evaluate metallurgical recovery of gold at depth.
Results of bottle roll cyanidation tests from two RC chip composite samples completed in 2021 include:
Composite One – 1.15g/t Au and 12.2g/t Ag head grade 90% recovery of Au and 84% recovery of Ag.
Composite Two – 0.63 g/t Au and 6.7 g/t Ag head grade, 92% recovery of Au and 70% recovery of Ag.
Between 5,000 to 8,000 meters of drilling is proposed during the operational season. Drilling will be completed in two to three stages with the initial stage focused on step-out drilling along the Main Zone and 4-Trench Trends (Figure 1.). Drilling planned for the latter part of the program will be evaluating the depth potential of surface veins exposed on the eastern portion of the property.
Results of drill step-out targets from 2021 drill holes include:
JES-21-50: 39.7m @ 0.96 g/t Au, including 1.5m @ 14. g/t Au
JES-21-47 : 47.7m @ 0.75 g/t Au including 3m @ 5.6 g/t Au and 22 g/t Ag
JES-21-38: 29m @ 0.71g/t Au
JES-21-43: 35.1m @ 0.66 g/t Au
JES-21-53 : 15.3m @ 1.1 g/t Au – New 4-Trench Trend
Exploration Trenching will be completed along the Triple Vein Zone to follow up on chip sampling from last year that returned, 4.5 g/t Au and 735 g/t Ag. Further surface sampling will be completed on the southeast portion of the property where work has been limited to date.
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 22,700 m of drilling have been completed to date. Significant results are highlighted below:
- 2021 Phase II RC Drilling Highlights include (all lengths are drilled thicknesses):
- 39.7m @ 0.96 g/t Au, including 1.5m @ 14. g/t Au
- 47.7m @ 0.75 g/t Au including 3m @ 5.6 g/t Au and 22 g/t Ag
- 29m @ 0.71g/t Au
- 35.1m @ 0.66 g/t Au
- 2020 Phase I RC Drilling Highlights include (all lengths are drilled thicknesses):
- 94.6m @ 1.6 g/t Au, including 9.2m @ 10.8 g/t Au and 38 g/t Ag;
- 41.2m @ 1.1 g/t Au, including 3.1m @ 6.0g/t Au and 12 g/t Ag ;
- 24.4m @ 2.5 g/t Au and 73 g/t Ag, including 1.5m @ 33.4 g/t Au and 1,090 g/t Ag
- 17,700m of Historic Core & RC drilling. Highlights include:
- 61.0m @ 0.8 g/t Au
- 16.5m @ 53.5g/t Au and 53 g/t Ag
- 13.0m @ 9.6 g/t Au
- 9.0m @ 10.2 g/t Au and 46 g/t Ag
Soil and Rock sampling results from undrilled areas indicate mineralization extends towards the southeast from the Main Zone and 4-Trench Zone. Recent Surface exploration has defined three new target areas: Triple Vein Zone, SE Vein Zone and 4 Trench Extension.
