Tumi Completes RC Drill Program at La Trini Silver-Gold Project, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 31, 2007) - Tumi Resources Limited ("Tumi" and/or "the Company") (TSX VENTURE:TM)(OTCBB:TUMIF)(FRANKFURT:TUY). David Henstridge, President of Tumi, announces the completion of the Phase 3 reverse circulation (RC) drill program at its 100% owned La Trini silver-gold project in Mexico. Fifteen drill holes were completed totalling 2,331.5m.

In September 2005, the Company announced the results of the initial 15 hole RC drill program (see press release dated September 29, 2005). In March 2007, a Phase 2 RC drill program comprising 11 holes and totalling 1,953m was completed in the core mineralized zone (see press release dated April 16, 2007).

These drill programs, coupled with the surface and underground sampling programs in and adjacent to the main target area, have defined a 400m long, northerly trending mineralized zone. The zone is 200m wide and remains open down-dip to the north. Within this zone there appears to be a higher grade corridor along the eastern edge, possibly adjacent to a major fault zone. Selected intervals from the first two drill programs, within the higher grade zone, include TRRC 6 (18.3m at 3.1 g/t Au and 150 g/t Ag), TRRC 9 (6.1m at 1.1 g/t Au and 201 g/t Ag), TRRC 10 (10.1m at 1.6 g/t Au and 130 g/t Ag), TRRC 11 (5.1m at 5 g/t Au and 184 g/t Ag) and TRRC 32 (24.4m grading 6.4 g/t Au and 1,629 g/t Ag.

The Phase 3 program has successfully completed its objectives. Three holes were drilled at 25m spacing around the high grade mineralization found in drill hole TRRC32; eleven holes were drilled on a 50m by 50m drill pattern to infill the mineralized zone over an area of about 200m by 250m, and one hole was drilled to the NE obliquely to the mineralized zone, to intersect what may be the fault controlling the limit of mineralization to the east. A surface plan of all drill holes completed in the core mineralized zone may be viewed at the following web link - www.tumiresources.com/en/latrini.shtml.

Samples from the program are still being split and progressively sent to International Plasma Labs Ltd. in Vancouver, Canada, for assay. As part of the Company's sample control program, blanks, known standards and duplicates are also being assayed. Results will be reported when available.

The qualified person for Tumi's projects, David Henstridge, a Fellow of the Australian Institute of Mining and Metallurgy and a Member of the Australian Institute of Geoscientists, has visited the La Trini project area to observe the Phase 3 drill program and sampling procedures and has verified the contents of this news release.

On behalf of the Board,

David Henstridge, President & CEO
