Calgary, Alberta – TheNewswire – May 4, 2021- Tocvan Ventures Corp. (CSE:TOC) (CNSX:TOC.CN) (“Tocvan” or the “Corporation”) is pleased to announce the results of ongoing metallurgical work at its flagship Pilar Gold-Silver Project in Sonora, Mexico. Preliminary results have been received from two composite samples taken from the previously released drill hole JES-20-32. Drill hole JES-20-32 is thought to be representative of the central portion of the Main Zone, which during Phase I drilling in December of 2020 intersected 94.6-meters at 1.6 g/t Au including 9.2m at 10.8 g/t Au and 38 g/t Ag from 57.9 to 152.5 meters. The samples consisted of a low-grade (0.63 g/t Au) and a medium-grade (1.2 g/t Au) composite to determine the susceptibility of dissolution of gold through cyanide bottle testing. The results show after a retention time of 48 hours, maximum dissolution can be reached of 91% for the low-grade composite and 92% for the medium-grade composite. A summary of the results are provided in Table 1. Samples were submitted to SGS Laboratories in Durango, Mexico for analysis.
