Blue Moon drills 50 m of 3.13% ZnEq at Blue Moon

2022-03-01 12:45 ET – News Release

Mr. Patrick McGrath reports


Blue Moon Metals Inc. has released the results of a fall 2021 exploration program at its property, a polymetallic project containing zinc, silver, gold and copper located in Mariposa county, California. Two key outcomes of the 2021 program are:

  • The discovery of an additional massive sulphide zone located west of the current resource, referred to as the south zone, which remains open to the south and up dip;
  • Extension of the American Eagle zone from surface to a depth of over 700 metres.

Patrick McGrath, chief executive officer, stated: “We are excited to announce the discovery of a promising new lens. We believe that this new lens has excellent potential to significantly increase our resource base and holds great promise for more massive sulphide lenses to be found south of our newly discovered south zone. Our priority will be to continue to delineate the south zone discovery with additional drilling. The American Eagle hole shows above-cut-off grades in this zone not only extends to the surface, but also is traceable down plunge for over 700 metres. The south zone and American Eagle zone have the potential to add additional orebodies, and the company could mine ore from multiple shafts.”

South zone (new discovery)

The newly discovered south zone was made by testing a geophysics conductor target, located west of the three previously discovered mineral zones and south of the American Eagle workings. This new zone was discovered deep and lateral to the previous mineral system. The zinc sulphide (sphalerite) encountered in this new discovery has sphalerite of a different hue from the other zones, which may indicate a separate emplacement pulse with slightly different timing. The mineralization cut in BM21-83 consists of bands and massive intervals of sphalerite, along with blebs of other sulphides, including pyrite, chalcopyrite and galena. Additional drilling is required to define the full extent and grade of this new massive sulphide lens. The mineralization cut in BM21-83 is similar to that found at the margins of other massive sulphide lenses on the property, and the company believes BM21-83 could be at the northern edge of this new massive sulphide lens.

The above thicknesses are core lengths. The estimated true thicknesses are approximately 50 per cent of the core lengths.

Hole BM21-83 also intersected a gold-rich horizon to the west of the south zone, which is possibly an extension of the American Eagle zone.

Drill hole BM21-81 tested the area between the American Eagle adit and the closest hole beneath the workings. BM21-81 confirmed the mineralization is continuous from surface, and the American Eagle lens has been shown to be traceable for over 700 metres down plunge.

The above thicknesses are core lengths. True thicknesses are approximately 60 per cent of the core lengths.

Drill hole BM21-82 was terminated early after the hole failed to flatten sufficiently and was redrilled with BM21-83, which hit its target. BM21-84 was attempting to test the southern extension of the American Eagle lens, but deviated too far to the north and shallowed such that it missed the planned test site. Drilling on the Blue Moon property can be challenging due to the alternating hardness of the rock, and even with special bits, the holes often deviate excessively and do not reach their planned targets.

Quality assurance/quality control

Drilling completed on the project in 2021 was supervised on site by Richard Walker, CPG. Mr. Walker collected and tracked samples and implemented a full QA/QC program using blanks, standards and duplicates to monitor analytical accuracy and precision. Drill core was logged and sampled in a secure core-processing and storage facility located at the Blue Moon site in Mariposa county, California. Core samples from the program were cut in half using a diamond blade rock saw, sealed on site and delivered directly by Mr. Walker to the ALS facility in Reno, Nev., for sample preparation and analysis, whereas the four-acid ICP-AES multielement package (33 elements) for zinc, copper, lead and silver ICP, as well as the base metal overlimits, was conducted at ALS Vancouver, both international accredited laboratories under ISO/IEC 17025 standards. Diamond core samples were analyzed using a combination of ALS’s ME-ICP61 process for low-level concentrations (ICP-ES four-acid digestion). Base metal overlimits have been finalized with assay-grade four-acid ICP and titration. Gold assaying was completed with FA430, a 30-gram fire assay with ICP-AAS finish and gravimetric finish for overlimits. Silver overlimits had gravimetric finish. Base metal overlimits were finalized with titration Zn-VOL50 (zinc), Cu-VOL61 (copper) and Pb-VOL70 (lead), and a silica wash was used between high-grade samples to ensure no sample carryover. No material differences were found in any of the company’s quality control samples nor ALS internal QA/QC samples. No QA/QC concerns were observed with the results shown in this report.

About Blue Moon Metals Inc.

Blue Moon Metals is currently advancing its Blue Moon polymetallic deposit, which contains zinc, gold, silver and copper. The deposit is open at depth and along strike. The Blue Moon National Instrument 43-101 mineral resource includes 7.8 million inferred tons at 8.07 per cent zinc equivalent (4.95 per cent zinc, 0.04 ounce per ton gold, 0.46 per cent copper and 1.33 ounces per ton silver), containing 771 million pounds of zinc, 300,000 ounces of gold, 71 million pounds of copper and 10 million ounces of silver. The NI 43-101 mineral resource report dated Nov. 14, 2018, was authored by Gary Giroux, PEng, and Lawrence O’Connor, a qualified person, and is entitled “Resource Estimate for the Blue Moon Massive Sulphide Occurrence.” The NI 43-101 report and the related press release with details on the resource are available at the company’s website and were filed on SEDAR on Nov. 20, 2018. The company also holds 100 per cent of the Yava polymetallic project in Nunavut, which is in the same volcanic lithologies and south of Glencore’s Hackett River deposit.
