Burlington, Ontario--(Newsfile Corp. - October 9, 2024) - Silver Bullet Mines Corp. (TSXV: SBMI) (OTCQB: SBMCF) ('SBMI' or 'the Company') is pleased to provide an update to the news release of September 24, 2024 in connection with the 500 pound sampling program of mineralized material from the third party owned past producing silver mine disclosed therein.
SBMI completed a detailed comprehensive metallurgical test of the material in a tightly controlled environment using the following methodology:
-
The material was weighed and set aside to ensure accuracy of the values.
-
All equipment used in the test was thoroughly cleaned to prevent potential contamination from other material run through the mill.
-
The material was then hand crushed and ground through the Company's crushing and pulverizing equipment.
-
The ground, screened material was then fed to the concentrating table.
-
Assays were taken of the feed material, concentrate, and tailings at various times during the test run to ensure the values were as accurate as possible.
The following numbers represent the average grade, recovery, and concentration ratio for the entire test. (a video of the test can be seen on the Company website).
-
Head grade - 19.2 ounces per ton silver
-
Concentrate grade - 307 .6 ounces per ton silver
-
Tailings grade- 2.1 ounces per ton silver
-
Concentration ratio - 18:1
The Company believes these are representative of both the sample and potentially the entire system. It also believes these numbers could increase as contact is made with the vein insitu. SBMI continues to run material and produce commercial grade concentrates for sale to its customers.
SBMI is very pleased with the progress it has made to date on the new property and coupled with the Buckeye material will provide excellent feed to the mill.
The Company will continue to provide future updates.
QA/QC
The metallurgical test described above was completed at the SBMI plant and all samples were assayed at multiple stages of the process. The test results as well as the assay results will provide input as to any adjustments that may be necessary to improve production efficiencies.
Readers are cautioned that samples are random by nature and may not be representative of the materials as a whole, whether from the surface piles or the historical workings or the Vein, and metallurgical results represent the sample tested and may not be representative of all mineralized material from the third party owned mine site.
All samples above were analyzed by SBMI at its facility near Globe, Arizona. They were processed through the Lab Jaw Crusher, Lab Hammer Mill and Splitter Box into an aliquot. Most of the pulverized aliquot was mixed with a flux and flour combination and melted in a crucible at 1,850 degree Fahrenheit, with the remainder being logged and archived. Upon cooling, the poured melt was in the form of a metal button and slag, following which a bone ash cupel was utilized to eliminate the lead in the button to form a bead. The bead was then weighed, following which a solution of 6 to 1 distilled water to nitric acid was utilized to dissolve the silver in the bead at approximately 175 degrees Fahrenheit.
