Black Mammoth Metals Achieves Positive Metallurgy Results at Happy Cat Gold Property
BMM: TSX-V
VANCOUVER, BC, July 15, 2021 /CNW/ - Black Mammoth Metals Corporation (TSXV: BMM) (OTC: LQRCF) ("Black Mammoth" or the "Company") is pleased to announce positive results from its preliminary metallurgical test program for gold recovery at the Company's Happy Cat property. A 13.6 kg sample from the near surface gold anomaly referred to in the Company's news release dated November 25, 2020 (the "Sample") was tested for Gravity Recoverable Gold ("GRG") at Met-Solve Laboratories ("Met-Solve"), Langley BC. The Sample was tested for GRG with the GRG tailings being further tested by cyanidation, with total gold recovery of 84.4%. A magnetic and a non-magnetic concentrate was produced with total GRG recovery of 38.8% (17.3% and 21.5% respectively). The GRG tailings were then tested for cyanidation with results indicating that 83% of the gold in the GRG tailings is readily leachable within 24 hours, with 80% gold recovery achieved in the first hour.
Sample material that was over 1.8mm in size (the "Oversize") was screened off before the test but still included in the weight of the Sample, which represents 23.2% of the Sample. This 1.8mm material was not tested for gold recovery which may slightly understate the total gold recovery percentage of 84.4%. The Company intends to conduct gold recovery testing on the Oversize along with further metallurgy work.
GRG Test:
The GRG test was a 3-stage test using a Falcon L40 centrifugal gravity concentrator (the "Falcon"). After screening off the Oversize, the magnetic fraction was removed to produce the magnetic concentrate. For the non-magnetic concentrate, the Sample was fed through the Falcon 3 times to produce 3 concentrates including an intermediate grind to 63 microns in between the 2nd and 3rd stage. The Sample's calculated head grade and assayed head grade was 0.97 g/t Au and 0.94 g/t Au respectively with the magnetic and non-magnetic concentrate having a mass pull of 0.5% and 2.16% respectively. A particle size analysis was conducted to determine the distribution of Au in each particle size class. In the head sample, a significant amount of Au occurs between 53 to 150 microns with over 70% of the Au occurring at less than 38 microns. In the tailings over 23% of the Au occurs between 75 to 106 microns and 67% of the Au occurring at less than 38 microns. No coarse gold or nugget effect was observed with the GRG test.
Prior to the GRG test at Met-Solve Laboratories, preliminary gravity tests were conducted at Hazen Research Inc. of Golden, Colorado and FLSmidth Minerals Testing and Research Centre, Salt Lake City, Utah.
Cyanidation Test:
A standard 24-hour bottle roll cyanidation leach test was conducted on the GRG tailings with an assayed head grade of 0.71 g/t Au and a calculated head grade of 0.70 g/t Au. 83% of the Au was leached within 24 hours, with 80% gold recovery achieved in the first hour. The leach residue contained the remaining 17% of the Au with a grade of 0.12 g/t Au. The remaining Au in the leach residue is believed to be locked in gangue minerals.
Sampling Program:
20 samples were collected in the immediate area of the near surface gold anomaly to aid the metallurgy tests and were delivered to Paragon Geochemical, Sparks, NV. Gold values ranged from a low of 0.21 g/t to a high of 2.6 g/t with an average value of 1.28 g/t. The samples were analyzed using Au-AA30; 30g fire assay, AQR digestion/AAS. The samples were collected and delivered by Adam Knight, PE and Independent Qualified Person as defined by NI 43-101.
Flotation Test:
A rougher flotation test targeting recovery of gold on the GRG tailings using a standard reagent scheme was conducted. The floatation concentrates were under the gravimetric assay limit of 0.9 g/t Au. This flotation test is considered preliminary so before flotation can be ruled out as a method of gold recovery, further testing is needed.

About Black Mammoth Metals Corporation:
Black Mammoth has 11,171,871 shares issued and outstanding, 11,556,871 shares fully diluted.
Along with the Company's 100% owned Happy Cat Gold Property, subject to underlying royalties, Black Mammoth has a 100% interest, subject to underlying royalties, in the Blanco Creek gold property in central Idaho which hosts three historic underground mines along 3550 meters (11,644 feet) of strike on the north-east trending regional Blanco Shear Zone. Exploration by two previous operators identified a geological target for the Blanco Creek property in the order of 1.7 to 2.48 million tons, grading 0.20 to 0.33 oz/ton Au (1.54 to 2.24 million tonnes, grading 6.85 to 11.31 g/tonne Au); see the Company's press release dated February 14th, 2017.
Black Mammoth cautions investors to note the potential quantity and grade of the geological target are conceptual in nature. A qualified person has not completed sufficient work to classify the geological target as mineral resources as defined by NI 43-101, and it is uncertain if future exploration will result in the target being delineated as mineral resources.
