[{"type":"text","content":"VanGold Reports Successful Bulk Sample Results at the El Pinguico Silver and Gold Project~ Gold Recoveries Average 75.18% ~VANCOUVER, BC / ACCESSWIRE / June 09, 2020 / VanGold Mining Corp (the \"Company\" or \"VanGold\") (TSXV:VGLD) reports results from its 1,039 tonne bulk sample and metallurgical test of material from its El Pinguico silver and gold project, located 7km south of the city of Guanajuato, Mexico.Bulk Sample and Metallurgical Test:As reported in the Company's June 2, 2020 news release, VanGold has completed its bulk sample and metallurgical test which consisted of delivering a total of 1039 wet tonnes of mineralized material from its El Pinguico silver and gold project for processing at Endeavour Silver Corp.'s (Endeavour) (TSX:EDR) nearby Bolanitos mill.

The VanGold Story Episode 1: https://youtu.be/ZL13PWaexsgGold and Silver Recoveries: The material used for this test came exclusively from the Company's surface stockpile of waste material which was left behind when mining ceased at El Pinguico in 1913. The material has been exposed to the elements since that time and was therefore somewhat oxidized. Despite this, recoveries of gold and silver were very good, and may point to better recoveries in the future from less oxidized material located within the mine itself.Average Recoveries:Gold: 75.18% Silver: 60.36%At times during the milling process the Company observed even higher gold and silver recoveries - up to 77.68% for gold and 67.19% for silver. The different grinding size and residency time within different circuits at the Bolanitos' mill accounts for much of these differences. The entire process helped us gain a better understanding of how these higher recoveries were reached, and how they can be replicated in the future. The Company may also pursue additional lab tests in order to replicate the higher numbers and potentially apply that knowledge at one of the local Guanajuato mills.Concentrate ratio 232 to 1: The Company delivered 1039 wet tonnes to Endeavour Silver's mill, which when dried became 1006 dry tonnes. With the help of VanGold's consulting metallurgist, Mr. Augustin Parra, Professor of Metallurgy at the University of Guanajuato, the Company chose to use certain silica depressors as reagents in the milling process. This procedure created a ver...
