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. << Table I: Summary of Caustic Fusion Processing Results, Cargo 1 kimberlite DH JI-CGI-03, 04 and 05 ------------------------------------------------------------------------- Hole Weight No. of Diamonds Recovered by Sieve Class No. (kg) ----------------------------------------------------------- +1.7 1.18 0.85 0.600 0.425 0.300 0.212 0.150 0.100 Total m m m mm mm mm mm mm mm ------------------------------------------------------------------------- 03 284 0 0 0 0 1 2 7 12 20 42 ------------------------------------------------------------------------- 04 647 1 1 0 2 5 17 24 53 86 189 ------------------------------------------------------------------------- 05 87 0 0 0 0 0 0 0 5 5 10 ------------------------------------------------------------------------- ------------------------------------------------------------------------- Total 1018 1 1 0 2 6 19 31 70 111 241 ------------------------------------------------------------------------- Notes: 1.

The diamonds are mostly white and transparent >> 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.

Hello Eric The Churchill play - SRM/NEM & SWV certainly appears to be shaping up into an interesting and active speculation. *OFF THE WIRE* Churchill Diamond Joint Venture 23 Priority Kimberlite DRILL Targets Confirmed DRILLING TO COMMENCE MAY 15-20/2003 Shear Minerals Ltd. (SRM) and Northern Empire Minerals Ltd. (NEM) today announced that 23 priority drill targets have been confirmed at the Churchill Diamond Project. The priority targets are slated to be drill tested during a program scheduled to begin between May 15-20th. The ground geophysical program announced on March 5, 2003 has been completed and the crew demobilised from site. The aim of the program was to collect ground geophysical data over priority targets identified in the 2002 airborne magnetic survey. During the program, 185 line-kilometres of total magnetic field surveys were conducted over 30 targets. On 19 of these targets, 60.4 line-km of horizontal loop electromagnetic (HLEM) data were acquired. Results from this program have been used to select targets for the up-coming drilling campaign and have identified 19 high priority and four moderate priority drill targets. “The recent ground geophysical program has identified a number of high quality drill targets,” says Pamela Strand, President of Shear Minerals. “This coupled with our favourable mineral chemistry, suggests that there is the potential for the discovery of diamondiferous kimberlites.” The Churchill Diamond Project, totaling more than 1.1 million acres, is located in Keewatin, Nunavut. The partners are optimistic that this year’s exploration may result in the discovery of an entirely new kimberlite cluster at Churchill. In the past year, Shear has advanced the project to the drill-ready stage by conducting a comprehensive exploration program that included kimberlite indicator mineral sampling, prospecting and geophysics. In January 2003, the partners approved a budget of $2.5 million program, that includes additional land acquisition, airborne and ground geophysical surveys, heavy minerals sampling, prospecting and drilling. All programs are under the supervision of Dean Besserer, P. Geol., of APEX Geoscience Ltd., a qualified person under NI 43-101. Shear holds a vested 51% interest and is operator of the Churchill Diamond Project; Hunter holds the remaining 49% participating interest. Northern Empire has an Option to earn into a 35% interest at Churchill by carrying Hunter for $750,000 in exploration expenditures. On behalf of the Board NORTHERN EMPIRE MINERALS LTD. /s/ “D.
