/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.
