Objective
Thundermin intends to undertake a diamond drilling program on
the Lebel property as follow-up to gold mineralization that has been found in
historical drilling and trenching on the property. The “Kirkland Lake Main
Break” (“KLMB”) is interpreted to cut the northwest corner of the property and
the potential exists to discover substantial gold at depth within this
structure.
Background
The Lebel property consists of one lease hold patent covering 16 hectares
that has recently been renewed and is in good standing until August 30,
2031.
The Lebel claim is located in northwest corner of Lebel Township
approximately one mile east of the Kirkland Lake City Centre. Access is
gained via Highway 66 east to the junction of the CNR railway tracks and
then by bush road.
The property was purchased in 1982 from Mr. M. J. Labine (“Labine”) of
Kirkland Lake. Labine is entitled to receive a 10% net profits interest
plus a 2% net smelter returns royalty on any future mineral production
revenue from the property.
Brief History
The Lebel property sits on the eastern end of the KLMB where over 23
million oz. of gold, second in North America to only the Porcupine
district, has been produced since 1913.
 The KLMB, or subsidiary break, is projected to run through the northwest
corner of the Lebel claim adjoining the Toburn Mine mineralization to
the west with the Glenora Mine mineralization to the east.
Production from the Toburn Mine, between 1915 to 1916 and between 1932
to 1953, amounted to approximately 570,000 oz. of gold and 135,000 oz.
of silver from 1,078,469 t of ore for a life-of-mine average grade of
16.5 g/t Au and 4.8 g/t Ag. The Toburn Mine has four shafts and 21
levels down to the 754.6 m elevation. On the lower levels, mining took
place to within 122 m of the western boundary of the Lebel claim. The
272 m level of the Toburn Mine was driven just north of the Lebel claim
to explore the extension of the Toburn mineralization onto the Glenora
property. In 1953, Toburn drilled two surface holes 61 m west of the
Lebel claim that reportedly cut ore grade gold mineralization.
The Glenora shaft, located 183 m northeast of the Lebel claim, is 142 m
deep with levels at 46, 92 and 137 m. This development work was
undertaken in 1936 but the mine closed in 1937 because the 8.7 g/t gold
values found in surface trenches could not be repeated underground. To
the east and at depth, the KLMB appears to be cut off and displaced by
the northeast-southeast trending Murdoch Creek Fault.
 The Lebel claim, upon which the Toburn and Glenora gold mineralization
dips, has seen only limited exploration. Two shallow holes drilled in
1933 encountered quartz veins and associated weak gold mineralization.
On the northwest corner of the property, three gold-bearing quartz veins
were encountered in trenches. A 14 m shaft was sunk on the most
southerly vein with reported gold values up to 10.3 g/t Au. The most
northerly trench, which continues off the Lebel claim toward the Glenora
shaft, contains reported values of up to 55.5 g/t Au. This vein system
appears to be part of the same structure that was encountered in the two
Toburn holes drilled 61 m west of the claim boundary.
 In 1983, The Harbinson Mining and Oil Group (which sold the claim to
Joutel Resources Limited, now Thundermin), drilled a 107.3 m long hole
to test the down dip extension of the gold mineralization encountered in
the surface trenches. The hole intersected two zones containing 2% to
15% disseminated pyrite with abundant sericite and quartz veinlets. The
first zone, in altered greywacke at a vertical depth of 23 m,
intersected 5.8 g/t Au over 2.4 m and the second zone, in altered
conglomerate at a vertical depth of 58 m, intersected 4.6 g/t Au over
2.4 m. The projection of these two zones to surface at a dip of 70˚ to
80˚ correlates with the mineralization encountered in the trenches and
with the average dip of the gold mineralization in the Toburn Mine to
the west.
Property Geology
The Lebel property is underlain dominantly by Timiskaming tuff and
conglomerate which dips moderately to the south. Porphyritic syenite has
been encountered in historic drilling and in trenches, but masses appear
to be small.
The KLMB is projected to cross the northwest corner of the property
adjoining the Toburn Mine and Glenora Mine mineralization. Gold-bearing
quartz veins exist in a shear zone where the Main Break is projected to
cross the property. This shear zone, which dips to the south at
approximately 70˚, has been explored by three trenches and a 14 m shaft.
Mineral Resources
No mineral resources have been defined on the property to date.
Metallurgical Test Work
No metallurgical test work has been undertaken to date. However,
no problems were encountered in milling ores from the adjacent Toburn Mine.
Infrastructure
The property is well located within Kirkland Lake where there is a well trained work force and ample
infrastructure to support a mining operation.
2012 Program
Thundermin intends to undertake approximately 2,000 m of diamond drilling
in 5-6 short holes on the Lebel property during 2012. The
purpose of this drilling will be to further test the down dip projection
of the gold mineralization intersected in the 1983 drilling undertaken
on the property.
QA/QC
The design of Thundermin’s drilling programs, Quality Assurance/Quality
Control and interpretation of results is under the control qualified
persons employing a QA/QC program consistent with NI 43-101 and industry
best practices.
