WOLVERINE MINERALS CORP. (TSX VENTURE:WLV)(FRANKFURT:4LP)
("Wolverine" or the "Company") is pleased to announce initial
positive results from its recently completed brown-field
exploration program at its Dade property. The Dade is located about
six kilometers northeast of the historical Mount Nansen Mine in the
southern part of the Dawson Range, Yukon Territory. The Company
identified a broad zone (37 m by 200 m) of altered wallrock with
two gold mineralized veins that is open to extension at depth and
along strike.
Key exploration activities consisted of satellite imagery
interpretation, prospecting and geological mapping, reconnaissance
and grid soil sampling (approximately 500 samples), magnetic and
radiometric airborne geophysical surveys (over 200 line kilometres)
and extensive CanDig and excavator trenching for approximately 800
m.
Highlights from the Trenching program include:
-- Delineation of a 200 m long vein/stockwork zone including the Grizzly
Vein that is open along strike in both directions;
-- 12.48 g/t gold over 6 m including 23.9 g/t gold over 3 m and 10.14 g/t
gold over 4 m across the previously identified Grizzly Vein;
-- 1.97 g/t gold over 9 m across a new sub-parallel vein; and
-- 1.71 g/t gold over 32 m across a stockwork zone that encompasses both
veins and mineralized wallrocks
The 1700 hectare Dade property hosts epithermal style gold veins
within Late Cretaceous to Tertiary, Prospector Mountain Suite
hornblende quartz diorite. The property hosts the gold mineralized
Grizzly Vein which was discovered in the 1920s. Most recent
exploration was restricted to shallow trenching in the late 1980's
and early 1990s. There is no outcrop in the vicinity of the
trenches and the area is covered with frozen colluvium.
Modern exploration on the property commenced in early June 2011
when two CanDig excavators reopened and deepened the earlier
bulldozer trenches. Discontinuous chip samples collected along the
floors of 11 trenches returned anomalous, but variable results.
Initial results ranged from background to 72.90 g/t gold (across 4
m). Re-analysis of initial samples at a different lab returned
consistent results with a peak value of 76.10 g/t gold (across 4
m). This was followed by a sampling program based on continuous
chip sampling. The same sample intervals were re-sampled and
generally confirmed earlier results, but a few high grade intervals
returned considerably lower values (72.90 vs. 5.97 g/t gold) while
some others returned considerably higher values (0.681 vs. 23.90
g/t gold). Re-sample values ranged from background to 23.90 g/t
gold (across 3 m).
Following receipt of these encouraging results, a larger
excavator was mobilized to the property and a series of 100 m long
trenches, spaced 25 m apart, were dug across the Grizzly Vein and
surrounding wallrocks. None of these excavator trenches directly
coincided with any of the CanDig trenches. Although a larger
excavator was used, permafrost was still a serious impediment in
previously un-trenched areas and some trenches could not be
completed to bedrock. Continuous chip samples were collected along
bedrock exposures, and composite samples of rock and soil were
taken from the trench floors where no bedrock was available.
Excavator trenching systematically exposed the Grizzly Vein in
all but one trench over a strike length of 200 m. The vein
generally consists of a single well-defined epithermal quartz vein
with a narrow halo of silicified wallrock. However, in some
trenches a second, sub-parallel vein, grading 1.97 g/t gold over 9
m, was exposed and the intervening wallrock was weakly fractured
and mineralized, to produce a broad stockwork zone. The
vein/stockwork exposures vary from 8 to 37 m in width. Table I
lists highlights from excavator trenching along the Grizzly Vein
(Figure 1 or the link below).

Soil samples were also taken just above bedrock on the floor of
all trenches. These samples returned values between background and
7260 ppb gold compared to background and 166 ppb gold from samples
taken closer to surface by conventional soil sampling techniques.
This marked increase with depth is attributed to the thick layer of
frozen colluvium that blankets most of the property, inhibiting
soil collection and hiding mineralization.
Preliminary geophysical interpretation from the airborne survey
show complimentary features, which may represent along-strike
continuations of the Grizzly Vein and associated structures
northeast of the trenching area.
Jim Dawson, Vice President of the Company commented, "The 2011
exploration program was highly successful because it significantly
expanded the area of interest, confirmed the tenor of known
mineralization, discovered a new vein and identified potential for
broad structural zones. The Grizzly Vein and related stockwork
mineralization are considered priority targets for continued
trenching and diamond drilling in 2012."
Analytical work was done by ALS Chemex with sample preparation
in Whitehorse, Yukon and assays and geochemical analyses in North
Vancouver, British Columbia. All rock samples were initially
analyzed for gold by fire assay followed by atomic absorption
(Au-AA24) and 35 other elements by inductively coupled plasma and
atomic emission spectrometry (ME-ICP41). Overlimit values for gold
were determined by fire assay and gravimetric finish (Au-GRA22).
All blank and standard samples passed QAQC reviews. Soil samples
were dried, screened to -180 microns, and then analyzed for 35
elements using an aqua regia digestion followed by inductively
coupled plasma and atomic emission spectrometry (ME-ICP41). An
additional 30 g charge was further analyzed for gold by fire assay
fusion with inductively coupled plasma and atomic emission
spectrometry (Au-ICP21).
Re-analyses of original CanDig trench samples was done by ACME
Labs in Vancouver, British Columbia. Coarse rejects from ALS Chemex
were crushed, split and pulverized to 200 mesh before being
processed by lead collection fire-assay fusion with AAS finish and
lead collection fire assay 30 g G-Fusion with gravimetric finish.
Blank and standard samples were inserted into the sample series
with coarse rejects. All standard and blank samples passed QAQC
reviews.
The 2011 fieldwork was conducted by Archer, Cathro &
Associates (1981) Limited under the supervision of Heather Smith,
P.Geo. and the guidance of James M. Dawson, P.Eng., who are both
qualified persons as defined by National Instrument 43-101. The
technical data in this news release has been reviewed and approved
by Ms. Smith and Mr. Dawson.
