Meanwhile, AMG is pleased to announce the appointment of Mr. Etienne Patris, who has nearly 40 years of mining experience, as Operations Manager for the site of Dieu Merci. Mr. Etienne Patris has already arrived in French Guyana, where he is carrying out his fortnight's work in accordance with health regulations.

However, production will be below the budget forecasts established before the start of the pandemic. In May 2020, out of the 7,007 tons of ore extracted from the El Santo Mine, 6,938 tons of ore were processed by the Ana Mana plan: The helical conveyors installed have reduced the moisture content of the concentrates and thus improved their quality: o Zinc concentrate: 8.98% (compared to an initial forecast of 10) o Lead concentrate: 8.93% (compared to an initial forecast of 10% for lead concentrate). Production of metals from concentrates: o Gold: 4kg o Silver: 79,000 oz o Lead: 1,857 tons o Zinc: 2,561 tons
