Hello Eric
Some very interesting data albeit too bloody late...
Twin Mining more than doubles land position at Jackson Inlet and reports on 2002 program results
TORONTO, May 13 /CNW/ - Twin Mining Corporation (TWG-TSX) is pleased to
report that the results of its till sampling program on its Jackson Inlet
diamond property, Brodeur Peninsula, Baffin Island, have triggered the staking
of an additional 119 claims, covering approximately 1,145 sq. km
(283,049 acres), contiguous with its existing land holdings. With the addition
of the new claims the Company's total land position at Jackson Inlet has more
than doubled in size and now covers 2,135 sq. km (527,487 acres).
The 2002 regional till sampling program over the main claim block
recovered a total of 489 till samples, each weighing approximately 15 kg. The
samples were collected at 400-meter intervals on lines spaced 2 to 4 km apart.
Pyrope and eclogitic garnet, Mg-ilmenite and spinel (confirmed by SEM-EDX)
were found in anomalous concentrations in numerous till samples within and
external to 2002 land holdings suggesting the potential for kimberlite sources
in addition to the drill-proven Freightrain and Cargo 1 pipes.
In particular, the discovery of a diamond in basal till (see drill
results below) near the Cargo2 magnetic anomaly situated 30 km southeast of
the Freightrain discovery strongly suggests the Cargo2 magnetic anomaly is
related to potentially diamondiferous, sub-cropping kimberlite. Apparent ice
movement in the area appears to be minimal. The new claims are contiguous to
the southern boundary of claims covering Cargo2 and the main claim block
(see claim map). They cover prospective ground adjacent to existing land
holdings, particularly in the Cargo2 area. New ground acquisition is based on
results of the analysis of diamond indicator mineral distribution patterns, as
well as ground considered to be within a structural corridor thought to be
prospective for kimberlite intrusions.
The Phase1 core drilling program for 2002 was designed to explore four
targets; three potential kimberlite targets defined by magnetic anomalies and
the Cargo1 pipe. To take advantage of weather conditions, the most distant
targets, ANO-9, ANO-10 and Cargo2 were drilled first and Cargo1 pipe
delineation drilling was performed at the end of the season. Testing of the
remaining potential kimberlite targets on the property will continue during
the 2003 exploration season.
Results from Phase1 exploration and drill testing suggests that there is
excellent potential for the discovery of additional diamondiferous kimberlites
other than Freightrain, where mini-bulk sampling has previously established
recovered grades of up to 34 cpht and modeled total content grades of up to
50 cpht, and Cargo1.
Caustic fusion processing of bouldery overburden material from Cargo2
core, obtained immediately above bedrock in JI-CG2-02 drill hole, produced a
diamond. Reinterpretation of the ground and airborne magnetic signatures of
Cargo2 established that drill holes tested the margins, rather than the core
of the magnetic anomaly. Consequently the Cargo2 magnetic anomaly is a high
priority potentially diamondiferous kimberlite target in the 2003 drilling
program. Drilling on magnetic anomalies associated with targets ANO-9 and
ANO-10 did not encounter kimberlite.
Caustic fusion analysis results from 1,018 kg of kimberlite core
recovered from Cargo1 pipe in 2002 are tabulated below. Three holes with an
aggregate total of 337 meters were drilled, of which 268.2 meters were in
kimberlite. The holes tested a portion of the Cargo1 magnetic feature where
kimberlite has been intersected in holes as much as 200 meters apart. Drilling
to date has not intersected the margins of the kimberlite body and it remains
open in all directions below surface.

The results were reviewed by AMEC E & C Serviced Limited ("AMEC"). The
main conclusion from this review: The results are consistent with the ones
previously reported from holes JI-CG1-01 and 02 (see press release July 10,
2002).
The planned 2003 program for the Jackson Inlet property will focus on
preliminary testing of other anomalies identified from geophysical data as
well as delineation drilling of the Freightrain kimberlite. AMEC considers
this approach to be reasonable. In addition, AMEC recommended that any future
sampling of the Cargo1 kimberlite should include the extraction of a 20 tonnes
sample to investigate the potential for larger diamonds, as well as a
preliminary estimation of diamond grades.
Rod Thomas, P.Geol., Twin Mining's recently appointed Vice President of
Exploration states: "These very encouraging results support the decision to
initiate an intense exploration effort in this emerging kimberlite province
discovered by Twin Mining in 2000. The Jackson Inlet project has produced
significant exploration results within a comparatively short period of time.
Diamonds in the Freightrain kimberlite are of sufficient quantity and quality
to approach or exceed ore-grade kimberlite in many locations of the world.
Consequently, a concerted effort to locate additional kimberlite pipes in the
area is clearly warranted. From an exploration perspective, the presence of
the diamondiferous Freightrain kimberlite with gem quality stones up to
1.557 carat and supportive kimberlite indicator mineral chemistry are key
ingredients for a successful diamond exploration program. This is complemented
by a large land position and the existence of and potential for additional
kimberlite targets. This project has excellent discovery potential."
Twin Mining is a founding member of the Eastern Arctic diamond play. In
addition to Twin Mining's Jackson Inlet property the existing land holdings of
Kennecott and De Beers on northern Baffin Island and the recent diamond
discoveries immediately to the south on the Melville Peninsula attest to the
exploration significance and diamond potential of the Eastern Arctic
kimberlite province.
Mr. John Lindsay, P.Eng., AMEC's Principal Metallurgist, is Twin Mining's
"Qualified Person" for diamond size distribution analysis, and Dallas Davis,
P.Eng., is Twin Mining's "Qualified Person" for the field component of the
2002 drilling program, as defined by National Instrument 43-101.
Twin Mining, in addition to exploring the Jackson Inlet diamond project
on Baffin Island and the TORNGAT diamond project on the east side of Ungava
Bay in northern Québec, is also developing the Atlanta Gold Project in Idaho,
United States of America.
