/CNW/ - Zephyr Minerals Ltd. ("Zephyr" or the "Company") (TSX-V: ZFR)
(OTC: ZPHYF) is pleased to announce its exploration plans for 2019 at its
Dawson
-Green Mountain
property in
Colorado, U.S.A.
With the additional land acquisition in the fall of 2018 and a newly
leased 259 hectare (640 acre) parcel from the
State of Colorado
, Zephyr now controls a mineralized
trend that is over 12 kilometers (7.5 miles) long. Zephyr's new geological model developed with the
assistance of Dr. Spry suggests that the genesis of the mineralization at
Dawson
-Green Mountain is
similar to the Broken Hill-type lead-zinc-silver deposits. This model was developed from the Broken
Hill ore body in
Australia
. Broken Hill was one of the largest ore bodies ever discovered. It contains
approximately 280 million tonnes of high grade lead and zinc (approximately 18% combined) plus
silver credits. Broken Hill is only used as a deposit model and is not necessarily reflective of the
mineralization that may be hosted on Dawson-Green Mountain property.
Zephyr is planning an airborne geophysical program consisting of magnetic and electromagnetic
surveys. Broken Hill-type deposits are highly magnetic while the surrounding rocks have a low
magnetic susceptibility. This makes a magnetic survey an ideal instrument for exploration of this
deposit type. Historic drill holes from 1979 and 1981 contain mineralization that is highly magnetic.
There were four historic drill holes drilled in the Grape Creek area and all intercepted high grade
mineralization. It should be noted that the silver to lead ratios are 50 to 1 in these historic drill holes.
This is at the very high end for silver to lead ratios in Broken Hill-type deposits. The silver is a driver
to boost the value and economics in these deposits. The results of these holes are presented in the
table below.

Very large Broken Hill-type deposits are found in structurally folded rocks where the mineralization is
thickened by the folding. The structure of the mineralization in the Grape Creek area strikes near
east-west and dips south at 60 degrees, whereas at the Green Mountain area the mineralization
strikes north-east and the dip is near vertical. This suggests there is possible folding to reconcile the
differences in the structural trend between the Grape Creek area and the Green Mountain area. The
goal of the airborne geophysical survey is to assess structural thickening at depth below the thin high
grade mineralization defined by the four historic drill holes.
Concurrent with the airborne geophysical program the Company plans to geologically map the Green
Mountain area. This is an area where a rock grab sample with only minor sulphides was located that
contained 13.6 g/t gold. This rock type is similar to the rocks that contain the Dawson Gold Deposit
in the
Dawson
area on the east side of the property. The geological mapping will help define the
rocks types, define any structural features in the area, as well as explore for gold showing at
surface.
Loren Komperdo
, President & CEO stated, "This summer will be incredibly exciting. We know that
Broken Hill type deposits are defined by their strong magnetic anomalies. We believe that the
planned airborne geophysical survey has the potential to discover such an anomaly, and in the event
of success would result in a highly prospective drill target. To the best of our knowledge, other than
the recent discovery by Cantex in the
Yukon
, this project represents the only active Broken Hill-type
exploration target in
North America
. Simultaneously we are continuing to expand our gold exploration
program at Green Mountain in the western portion of our holdings where there is excellent potential
to discover another gold deposit similar to the Dawson Gold Deposit in the east."
