Alianza Minerals confirms new silver-bearing veins in drilling at Bighorn Zone, Haldane Silver Property, YT
22 Oktober 2019 - 3:00PM
Alianza Minerals Ltd. (
TSX-V:
ANZ) (“
Alianza” or the
“Company”) reports drilling at the Haldane Silver
Property has confirmed the presence of new silver-bearing vein
targets at the Bighorn Zone. The first two holes of the program
tested the Ross and Bighorn soil geochemical anomalies, neither of
which has been previously tested by drilling. Highlights of the
first hole at the Bighorn Anomaly include
125 g/t Ag and
4.4% Pb over 2.35 metres from 154.15 metres depth.
Additional assay results are pending for the two additional holes
drilled at the Mt. Haldane Vein System (MHVS) area and will be
reported next.
The Haldane high-grade silver target is located
in the historic Keno Hill Mining District of Yukon Territory. The
8,579 hectare property is located 25 km west of Keno City, YT in
the western portion of the district. The 2019 Phase II program
targeted three main areas: the newly identified Bighorn and Ross
anomalies, and the Mt. Haldane Vein System (MHVS). One hole was
completed at each of the Ross and Bighorn anomalies, with two holes
targeting the A and B veins of the Middlecoff Zone in the Mt.
Haldane Vein System target area. A total of 963 metres were cored
in four holes.
The Bighorn result comes from the widest of four
vein-structures intersected. This structure was cut from 150 to 159
m, and includes the 2.35 m averaging 125
g/t Ag and 4.4% Pb from 154.15 metres depth within a wider
6.60 m intersection that returned 50.1 g/t Ag and 1.85% Pb from
151.7 m. One hole at the Ross anomaly intersected zones of
anomalous veining and disseminated mineralization in rocks
overlying the prospective lower Keno Hill quartzite unit. It is
believed that these are the manifestation of the target structures
and that they may form cohesive veins at depth in the permissive
units.
Jason Weber, P.Geo., President and CEO of
Alianza noted that, “The first-ever drill hole at the Bighorn Zone,
almost three kilometres from known mineralization, successfully
intersected at least 4 mineralized structures confirming a new zone
for systematic follow-up drilling. The Ross hole, which also tested
a new area, returned only anomalous lead and silver values, but
appears to have intersected weak structures that may be conducive
to forming veins in the more brittle Lower Keno Hill Quartzite that
lies below.”
Bighorn Target
At the Bighorn Zone, drill hole HLD19-15 (351 m
at -50°), cut a west to east cross section near the centre of the
900 by 150 metre, north-south trending, Pb-Ag-Sn soil anomaly.
Earlier surface mapping and trenching in 2019 indicates the anomaly
is related to several roughly north-south striking faults and/or
silicified breccia zones. Trenching within the anomaly exposed wide
sections of elevated lead, up to 0.25% Pb over 10.5 m, in
silicified and brecciated quartzite and phyllite of the lower Keno
Hill Formation, generally leached of all sulphide.
The drill hole intersected four significant
north trending, steep faults, plus several smaller faults all with
associated mineralization. The most significant of these faults
occurs from 150 to 159 metres and consists of gossanous, sheared
and brecciated phyllitic quartzite with up to 3% scattered galena
blebs. A 2.35 m section of leached carbonate-quartz veining within
this fault returned 125 g/t Ag and 4.4% Pb. This fault appears to
correlate with a silicified breccia/fault zone on surface (Trench
BH03). The other faults that were intersected have locally weak to
strong silicification, bleaching due to white mica, and gossanous
fractures after iron-rich carbonate. Mineralization consists of
siderite-quartz-galena-sphalerite veins and/or breccia fillings,
typical mineralogy for the vein-fault zones in the Keno Hill
district. Locally, poor core recovery within these faults may have
negatively impacted the results, such as in the interval from
196.95 to 198.00 m where despite recovering only 45% of the core
from the interval, it assayed 48.2 g/t Ag, 2.08% Pb and 2.73%
Zn.

Ross Target
The first hole of the program tested the Ross
Anomaly, a 300m by 100 m Pb-Zn-Ag soil anomaly, approximately 3 km
along trend from the Middlecoff Zone on the Mt Haldane Vein System.
The anomaly sits in schist and phyllite of the Upper Keno Hill
Formation (Sourdough Member) in the immediate hanging wall to the
contact with the Lower Keno Hill Quartzite. The Lower Keno Hill
consists of massive quartzite and phyllitic quartzite, which are
much better hosts for the vein-fault style of mineralization
present on the Haldane Property and elsewhere in the Keno Hill
District.
Drill hole HLD19-14 was drilled east at -50° for
225 m to cut under the soil anomaly looking for the lower Keno Hill
contact and a potential structure related to the soil geochemical
anomaly. The hole passed below the anomaly completely within schist
and phyllite of the Sourdough Member. The hole contained evidence
of mineralization in the schist/phyllite, including manganese and
iron oxides in veinlets and shears at 69-71 m, and <0.1%
galena-sphalerite disseminated along foliation at 87.4 to 94.0 m
but no significant assays were returned. The hole intersected
quartzite below 180 m suggesting the initial target may exist
deeper on the section.
