[{"type":"text","content":"Silver Bullet Mines Corp. (SBMI) Confirms Anomalous Platinum Group Elements (PGE) in Some Samples on Its Richmond Basin, Arizona PropertyBurlington, Ontario--(Newsfile Corp. - March 29, 2023) - Silver Bullet Mines Corp. (TSXV: SBMI) (OTCQB: SBMCF) ('SBMI' or 'the Company') is pleased to announce it has received the assay results from a third party independent (ISO 17025-2017) accredited lab, American Assay Laboratories. These are the 'check assays' for material tested and reported in September and October, 2022. These results confirm the presence of anomalous platinum group elements (PGE) values in some of the material. QA/QCA total of six samples, 6 duplicates, 4 standards and one blank sample were assayed. The samples were collected by the mine crew from various material at the Buckeye Mine and were crushed and ground to a powder at the Company's assay lab with the powder retained in marked sample bags. A portion of each of these bags was retained and a portion was inserted in another labelled bag and then delivered by a courier in Globe, Arizona to American Assay Laboratories in Nevada. The blank and standards were included as well. American Assay Laboratories used a similar assay finish procedure as the first lab, Lone Pine, namely ICP-MS. Lone Pine used a 4 acid dissolution of a 200 milligram sample and American Assay Laboratories used a sodium peroxide fusion of a 5 gram sample. To further confirm the presence of platinum a repeat Fire Assay was undertaken. For this method the sample was fused in a ceramic crucible with litharge, sodium carbonate, borax and flour at 1080°C. From this a 25-50 gram lead button was cupelled in a magnesite cupel at 900° for 60 minutes. The silver bead was then parted with concentrated nitric acid followed by hydrochloric acid to generate chlorine and nitrosoyl chloride that dissolved the PGM sponge. Digested samples were read on an ICP-AES. The PGE results obtained from American Assay Laboratories were in line with a 1995 historic report and that of Lone Pine.American Assay Laboratories assayed for silver, gold, iridium, osmium, palladium, platinum, rhodium and ruthenium (see chart below). The green highlighted samples relate to standards and the yellow to blanks.Table 1To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/8464/160434_64c7c5b...
