TOCVAN RELEASES SURFACE EXPLORATION RESULTS IDENTIFYING UNDRILLED HIGH-GRADE AU-AG TARGET ZONES HIGHLIGHTED BY: 9.2 G/T AU AND 279 G/T AG; 6.6 G/T AU AND 433 G/T AG; AND 1.3 G/T AU AND 524 G/T AG
Tocvan Ventures Corp. and Colibri Resource Corp. have released surface sample results from their Pilar Au-Ag (gold-silver) project in Sonora, Mexico. A surface exploration program was conducted in December following up on target areas identified earlier in 2021. A total of 59 samples were collected with 21 samples returning values greater than 0.5 gram per tonne gold. Sampling defined several new target areas yet to be drilled. The Main zone has been expanded with high-grade Au-Ag values (9.2 g/t Au and 279 g/t Ag) along the southeast extent hosted in a silicified quartz vein breccia. The 4-T trend has been extended to the southeast 100 metres with high-grade Au-Ag values, highlighted by 6.6 g/t Au and 433 g/t Ag hosted in a strongly silicified fault. A new vein corridor identified by several artisanal workings and shafts over a 200-metre strike has returned high-grade silver values highlighted by 524 g/t Ag and 1.3 g/t Au hosted in a silicified quartz vein breccia. In addition, mineralization has been identified farther to the south (300 metres) highlighted by 3.1 g/t Au and 27 g/t Ag.
Surface results highlights
Main zone expansion:
- New alteration corridor identified adjacent to Main zone, highlighted by:
- 9.2 g/t Au and 279 g/t Ag;
- 4-T trend extended over 100 metres to the southeast, highlighted by:
- 6.6 g/t Au and 433 g/t Ag;
- 3.5 g/t Au and 645 g/t Ag;
- 4.9 g/t Au and 32 g/t Ag.
New vein target defined over 200-metre strike, highlighted by:
- 1.3 g/t Au and 524 g/t Ag;
- 1.3 g/t Au and 94 g/t Ag;
- 1.1 g/t Au and 48 g/t Ag.
South zone reconnaissance sampling returned:
- 3.1 g/t Au and 27 g/t Ag;
- 2.5 g/t Au and two g/t Ag;
- 1.0 g/t Au and 29 g/t Ag.
“The results from our recent surface exploration program have further confirmed the significant distribution of untested drill targets at Pilar,” commented chief executive officer Brodie Sutherland. “We have now defined a 1.2 km corridor of Au-Ag mineralization at Pilar, half of which has seen no drilling. We plan to test these target areas with systematic drilling during the phase 3 drill program currently under way. Two thousand twenty-two will be an important year for the advancement of Pilar as we look to better understand the extent of the mineralized system. ”

4-T refers to the 4-Trench prospective trend. NVZ refers to the new
vein target identified by sampling and mapping. Grab samples
are selective in nature and may not be representative of
broader mineralized zones. Chip samples are taken over 0.5 to two m
lengths.
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 northwest 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 northwest-southeast trend of mineralization. Over 22,700 metres of drilling have been completed to date. Significant results are highlighted below:
- 2021 phase 2 RC drilling highlights include (all lengths are drilled thicknesses):
- 39.7 m at 0.96 g/t Au, including 1.5 m at 14 g/t Au;
- 47.7 m at 0.70 g/t Au, including three m at 5.6 g/t Au and 22 g/t Ag;
- 29 m at 0.71 g/t Au;
- 35.1 m at 0.66 g/t Au;
- 2020 phase 1 RC drilling highlights include (all lengths are drilled thicknesses):
- 94.6 m at 1.6 g/t Au, including 9.2 m at 10.8 g/t Au and 38 g/t Ag;
- 41.2 m at 1.1 g/t Au, including 3.1 m at 6.0 g/t Au and 12 g/t Ag;
- 24.4 m at 2.5 g/t Au and 73 g/t Ag, including 1.5 m at 33.4 g/t Au and 1,090 g/t Ag;
- 17,700 m of historic core RC drilling; highlights include:
- 61.0 m at 0.8 g/t Au;
- 16.5 m at 53.5 g/t Au and 53 g/t Ag;
- 13.0 m at 9.6 g/t Au;
- 9.0 m at 10.2 g/t Au and 46 g/t Ag.
Soil and rock sampling results from undrilled areas indicate mineralization extends toward 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.
Quality assurance/quality control
RC chips were shipped for sample preparation to ALS in Hermosillo, Sonora, Mexico, and for analysis at the ALS laboratory in North Vancouver. The ALS Hermosillo and North Vancouver facilities are International Organization for Standardization 9001 and International Organization for Standardization/International Electrotechnical Commission 17025 certified. Gold was analyzed using 50-gram nominal weight fire assay with atomic absorption spectroscopy finish. Overlimits for gold (over 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 (inductively coupled plasma) finish. Overlimit analyses for silver (over 100 g/t) were reassayed using an ore-grade four-acid digestion with ICP-AES (inductively coupled plasma atomic emission spectroscopy) 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.
