HALIFAX, May 5, 2020 /CNW/ - Zephyr Minerals Ltd.
("Zephyr" or the "Company") (TSXV: ZFR) (OTC: ZPHYF),
is pleased to announce that it has discovered the silver in
historic drill holes GC-8 and GC-9 is hosted by the same rare
silver mineral that is host to the silver at the Broken Hill and
Cannington silver-lead-zinc mines
in Australia, as well as a silver
enriched variant.
Petrographic studies coupled with electron microprobe analyses
has been completed on silver-lead-zinc mineralization from the
massive sulfide zone along the Dawson-Green
Mountain ("DGM") trend by Dr. Paul Spry, Economic Geology professor at the
University of Iowa and Zephyr's
technical advisor. Dr. Spry is a world-renowned expert on Broken
Hill Type ("BHT"), silver-lead-zinc deposits. Results of
these studies show the DGM trend is dominated by the metallic
minerals sphalerite, pyrite, chalcopyrite, galena, magnetic
pyrrhotite, magnetite, and gahnite. The magnetic anomaly associated
with the DGM trend is related to the presence of magnetite and
magnetic pyrrhotite. At the Cannington mine in Australia (a BHT deposit) the deposit's
magnetic signature is primarily due to the presence of magnetite
and minor pyrrhotite in the silver-lead-zinc mineralization.
Electron microprobe analyses of historic (US Borax, 1981), drill
core from holes GC-8 and GC-9 has demonstrated that the majority of
the silver in the El Plomo section of the DGM trend is found in a
recently named new mineral argentotetrahedrite
(Ag6(Cu4Fe2)Sb4S12S). Argentotetrahedrite contains up to 34 weight
percent silver. In addition, minor amounts of silver are hosted in
tetrahedrite with up to 4 weight percent silver and galena with up
to 0.32 weight percent silver. At the Broken Hill and Cannington mines in Australia, the main silver mineral is
freibergite ((Ag,Cu,Fe)12(Sb,As)4S13). Argentotetrahedrite is a
subgroup of the silver sulfosalt mineral freibergite. The presence
of the high silver mineral, argentotetrahedrite versus freibergite
suggests a BHT discovery at El Plomo could potentially have a
higher silver-lead ratio than at Cannington which stood at 44 g/t silver per 1%
lead.
Loren Komperdo, President &
CEO stated "I am very pleased to find the majority of the silver is
hosted in the mineral argentotetrahedrite which is a freibergite
variant with extra silver. These are both rare silver minerals and
it bodes well that the silver at Zephyr's El Plomo section is
hosted in the same minerals as found in Broken Hill and
Cannington".
About Zephyr Minerals Ltd.
Zephyr Minerals Ltd. continues to advance its 100% owned high
grade Dawson-Green Mountain Project in Colorado, USA. After expanding it's land
package to 1,385 hectares (3,430 acres) the Company now controls a
12.2 km long Dawson-Green Mountain mineralized trend. The central
3.2 km long El Plomo section is the focus for potential Broken Hill
Type silver-lead-zinc mineralization and the east and west
sections, Dawson and Green Mountain respectively are being targeted
for gold. The Dawson section is
currently host to a high grade inferred gold resource. The Company
believes the combined Dawson and
Green Mountain sections
encompassing approximately 9 km of mineralized trend provide
excellent resource expansion potential.
