VANCOUVER,
Oct. 18, 2012 /CNW/ - Westminster
Resources Ltd. ("WMR" or "the Company") has successfully completed
its 2012 Phase One $1,600,000
exploration program at the Cumbral-San Bartolo property. Located in
Sonora, Mexico, work included a
3D-Induced Polarization (IP) and ground magnetic geophysical survey
covering 219 line kilometers of survey grid, over 5,000 soil
geochemical samples, rock prospecting-geological mapping (over 700
samples) and a diamond drill program of seven holes (total 1,641
meters) on the Cumbral trend. The exploration program was funded by
Capstone Mining Corp. in accordance with a $9,300,000 agreement that was announced in
April 2012 (WMR 12-02, April 17l,
2012).
Exploration Highlights
- Cumbral trend drilling intersects IOCG alteration and
mineralization containing Cu+Ag+Au grades in the oxide zone.
- Rock sampling program across the grid identifies widespread
visible copper at surface and discovers 8 new targets across the 9
Km X 9 Km area.
- A greater than 1 Km X 1Km 3D-IP high chargeability anomaly, the
Montoso target, is interpreted as a classic porphyry-style deposit
environment.
- Multi-element soil geochemical anomalies across the grid
coincide with extensive alteration and mineralized zones.
- Phase Two exploration planning near completion (to include
5,400 meters of drilling).
The large project area (9 Km X 9 Km) has been
divided into A, B, C and D grid blocks. See website for maps at
http://www.westminsterres.com/investor/drill_gallery/index.php The
initial discovery of IOCG-style alteration and mineralization is
located in the northern A Block where a series of chargeability ±
resistivity ± magnetic high responses were identified as the
Cumbral trend during 2D-IP and MAG geophysical surveying in
November 2011. These geophysical
targets as well as intense potassic + silica + iron oxide and often
copper oxide-rich veins and brecciated subcrops (IOCG) were tested
by preliminary drilling with results presented in Table A.
Since discovery in 2011 of the Block A Cumbral
trend and WMR's earlier exploration at the San Bartolo trend in Block D (9 kilometers to
the south) a detailed, systematic exploration program has been
undertaken across all four grid blocks with 219 line-kilometers of
survey grid established a connection between the Cumbral trend and
San Bartolo trend. Distributed
across all four grid blocks, there are 143 samples (or about 20% of
the 704 rock chip and grab samples) which contain visual evidence
of copper mineralization by the presence of malachite, azurite, or
chrysocolla. Most mineralized subcrops and outcrops, however,
showed evidence of strong oxidation and leaching of sulphides with
extensive iron oxide and siliceous alteration. The project's
extensive hydrothermal systems display variable styles of
mineralization and grades depending upon the extent of oxidation
and leaching, and are characteristic of both IOCGs and porphyry
systems.
In the discovery area, Block A, Cumbral North
surface targets have grab samples with grades as high as 1.21%
copper, multi-grams of silver (highest 31.0 g/t) and gold to 589
ppb with generally low lead and zinc. Surface mineralization in the
main Cumbral trend exposures have grades similar to the oxide zones
encountered in the first drill holes (see Table A).
In Block B the "Lost Cumbral Mine" and its
strike extension some 400 meters south have been identified as a
series of collapsed workings and pits of unknown age and origin.
The highest grade sample assayed 412 g/t silver, 1,104 ppb gold
with 0.1% lead and very high bismuth. The south extension grab
sample from diggings graded 0.5% copper, 7.6 g/t silver and 3,790
ppb gold. The "Lost Cumbral Mine" and the San Bartolo trend of old workings are only two
of the numerous unnamed historic pits and workings being discovered
across the grid area.
In the central Block C grid several new
mineralized targets were discovered, commonly with strike lengths
of several hundreds of meters traceable on surface as outcropping
zones of iron-quartz-rich breccias, veins and stockworks. The Bee
Showing has elevated Mo and Zn with minor copper and silver grades
to 11.59 g/t and gold to 2,443 ppb. At Weakele Road Pit grab
samples graded up to 1.27% copper, 197 g/t silver, 1,509 ppb gold
with 0.1% lead and 0.2% zinc. Further to the east in Block C, the
Two Glens and Two Ronnies mineralized trends are characterized by
highly anomalous Mo+As+Hg+Sb and up to 5.9% lead, 0.3% zinc with
silver grading 214 g/t and gold 2,880 ppb. These showings appear to
be related to a series of NW-SE trending resistivity highs and lows
as modeled in the 3D-IP survey covering the area. The highest grade
rock sample collected to date is located in Block C (0.97% Cu, 26.2
g/t Ag, 26.39 g/t Au).
The west-central portion of the Block D grid
area is dominated by a large 3D-IP high chargeability anomaly named
the Montoso target. It is partially overburden covered but where
manifested at surface it is characterized by intense destructive
white clay alteration and iron oxide staining and granitoid
intrusives. To the north and on the Montoso's eastern periphery
several occurrences of silver-bearing veins and malachite float
samples have been located. The highest grade vein-float located in
an area of intense red soil assayed 0.5% copper, 0.89% lead, 0.52%
zinc, 2,000 ppm molybdenum and 75.87 g/t silver and 1,716 ppb gold.
In eastern Block D the San Bartolo
silver trend occurs adjacent to the high chargeability Montoso
target. Westminster previously
identified in 2011 at San Bartolo
a 1.4 kilometer strike that is characterized by multi-gram silver
intercepts in numerous intervals in 16 shallow drill holes (see
WMR11-10, October 4, 2011). This
drill program completed prior to the 3D-IP survey focused on
extensive areas of silver geochemical soil anomalies associated
with numerous historic pits and diggings and before discovery of
the new Montoso target now interpreted as the main center of a
porphyry system.
The Montoso target in Block D was interpreted
from analysis of the 3D-IP geophysical survey (inversion modeling)
to be an area with coincident low resistivity and high
chargeability ranging from 35ms to over 65ms. Similar to other
known porphyry deposit styles of chargeability response, the
Montoso anomaly has been modeled in 3D to identify potentially
mineralized zones. Plan views and sections of the inverted
chargeability indicate that at 200 meters depth the 35ms target is
over one kilometer long by one kilometer wide with its dimensions
increasing at depths of over 400 meters. Plots and maps of the
Montoso target geophysical response are available on our website at
http://www.westminsterres.com/investor/geo_gallery/index.php The
impressive areal extent of the Montoso chargeability target when
projected to surface is surrounded by ring-like patterns of
anomalous soil geochemical contents for the elements Mo, Ag, Au and
Cu similar to known copper districts where silver vein
mineralization is often found up to several kilometers from the
core area of the main porphyry. The setting of the extensive silver
in soil anomaly related to the San
Bartolo silver vein systems may represent such an adjacent
setting at Montoso.
The ground magnetic geophysical survey data for
the four Blocks is currently being processed using inversion
modelling and then will be incorporated into the IP chargeability
and resistivity Montoso models. Previous Heli-MAG surveying and
preliminary ground magnetic plots do show typical porphyry
deposit-style high and low magnetic patterns within the area of the
Montoso IP target further suggesting that a mineralized system
covering several square kilometers may be present.
Drilling results from significant samples from
all seven Cumbral trend drill holes are presented in Table A.
Chargeability targets of 8ms or greater were targeted in holes 1B,
1D, 3A and 4A with all holes intersecting granodiorite,
quartz-feldspar pink granite or fine to medium grained dark
diorite. Holes 1D and 1B showed variable potassic and epidote
alteration accompanied by iron oxide veinlets. Holes 3A and 4A
located 800 and 1,200 meters from Target One displayed iron
carbonate and epidote alteration. All holes contained minor pyrite
sulphides at depth below the oxide zone. Magnetic response in the
area appears to be associated with the diorite intrusive phase.
Holes 5, 6 and 7 targeted IOCG alteration and copper oxide
silver-gold mineralization adjacent to chargeability Target One.
Iron-oxide-copper malachite veins and breccia similar to float seen
at surface were intersected in these holes in close proximity to
the pink granite unit and in potassic altered granodiorite in holes
5 and 7. Hole 6 intersected dark diorite and a vertical quartz
vein. At 159.7 meters depth a diorite hosted one meter interval
graded 0.25% copper as unleached chalcopyrite stringers were
present (Table A). Location maps and 3D inversion IP models of
drill holes are available on our website at
http://www.westminsterres.com/investor/geo_gallery/index.php
All rock and core samples were submitted for
preparation and analysis at Acme Analytical Laboratories Ltd.,
Vancouver with QA-QC and sampling
protocol fully described in Press Release WMR 12-06, August 14, 2012. True intercept thickness
estimates are unknown at this time.
Glen Indra
President of the Company stated: "Our exploration success
at the Cumbral-San Bartolo project definitely suggests the presence
of district-scale mineralization and, with the discovery of the
Montoso target, our exploration activities will have a refined
focus at this apparent porphyry system. In summary, extensive early
stage exploration over most of the 9 Km X 9 Km property, has
advanced the Project to where a major portion of the Phase Two
program will be dedicated to drilling. The Phase Two $1,700,000 Program planning is substantially
complete and management is eager to implement an early start
up."
