[{"type":"text","content":"Cabral Gold Receives Excellent Column-Leach Test Results from MG Gold-in-Oxide Material, Cuiú Cuiú Gold DistrictVancouver, British Columbia--(Newsfile Corp. - June 21, 2022) -  Cabral Gold Inc. (TSXV: CBR) (OTC PINK: CBGZF)  (\"Cabral\" or the \"Company\") is pleased to provide results from column-leach test work on unconsolidated gold-bearing oxide material from the MG target within the Cuiú Cuiú gold district in northern Brazil.Highlights are as follows:Column-leach test work indicates heap-leach processing is viable at Cuiú Cuiú, which should result in lower initial capital and operating costsGold recoveries based on the calculated gold content of the bulk sample were 82% after 70 days. Recoveries after 15 days were 70% and recoveries after 30 days were 78% Leached gold recoveries were 0.974 g/t gold, significantly higher than the average assayed head grade of 0.896 g/t gold from head screen analysis of the composite bulk sample taken prior to the leach testAlan Carter, Cabral's President and CEO commented, \"These column leach test results are very encouraging and indicate that the gold-in-oxide material at Cuiú Cuiú is amenable to heap-leach processing. The overall leach recovery of 82% is excellent and higher than most heap leach gold mines that are currently in operation. Furthermore, the results indicate that the composite sample used for the column leach tests may contain more gold and be higher grade than the assays from the composite sample indicate. The possible reason for this is that coarse gold particles may occur within the oxide material. On the basis of these results, Cabral plans to move forward with a Preliminary Economic Analysis of the gold-in-oxide blanket material at Cuiú Cuiú as soon as possible to demonstrate the economic viability of the gold-in-oxide blankets.\" Column Leach testsFollowing the initial discovery of the MG gold-in-oxide blanket in early 2021 (see press release dated April 15, 2021), Cabral shipped approximately 400kg of mineralized oxide material from MG to the Kappes, Cassiday & Associates lab in Reno, Nevada to conduct heap-leach metallurgical testing. To create the bulk sample, seven sub-populations of various oxide materials and grades were sampled from five HQ diamond-drill holes. (see Table 1 and press ...
