TUMI RESOURCES LIMITED ------------------------------------- Date: April 04, 2005 /s/ David Henstridge ------------------------------ ------------------------------------- David Henstridge, President & CEO TUMI RESOURCES LIMITED #1305 - 1090 West Georgia Street Vancouver, BC V6E 3V7 Tel: (604) 685-9316 Fax: (604) 683-1585 Website: www.tumiresources.com TSX Venture Symbol: TM Frankfurt Exchange: TUY OTCBB: TUMIF -------------------------------------------------------------------------------- NEWS RELEASE APRIL 4, 2005 EXPLORATION PROGRAM UNDERWAY AT THE LA TRINI SILVER-GOLD PROPERTY, JALISCO, MEXICO VANCOUVER, CANADA - TUMI RESOURCES LIMITED (THE "COMPANY') (TSXV - TM; OTCBB - TUMIF; FRANKFURT - TUY). David Henstridge, President, is pleased to report the start of the exploration program at the La Trini silver-gold property ("La Trini"). The La Trini Claims are located in the Jalisco silver belt about 100 kilometres northwest of Guadalajara, Jalisco State, Mexico. The La Trini Property, under option by the Company, lies within the Hostotipaquillo mining district and is underlain by the Tertiary Sierra Madre Occidental volcanic province and younger intrusive rocks. The La Trini silver/gold mineralization outcrops within a gently dipping, tabular, silicified rhyolite breccia which will be evaluated by the Company for open-pit mining potential. At La Trini an historical resource estimate was made in 1980 by Pincock, Allen & Holt Inc. ("PAH") an independent engineering consultancy firm. The resource estimate was based on the results from 26 diamond drill holes undertaken on behalf of NL Industries Inc. The estimate was calculated using vertical cross-sections constructed through the mineralized blocks at a spacing of 45m. Using a 2m minimum thickness at a cut-off grade of 32 g/t silver and a tonnage factor of 2.7 tonnes/cubic.metre a resource of 1,262,000 tonnes at a grade of 125 g/t silver and 1.24 g/t gold was calculated. Using the same calculation parameters with a cut-off grade of 125 g/t silver, the resource calculation gave 527,000 tonnes at a grade of 217 g/t silver and 2.5 g/t gold. Although PAH categorized these tonnes as reserves, the calculations are conceptual and insufficient exploration has been completed to define a NI 43-101 compliant mineral resource on the property. PAH identified two areas of concern namely the wide spaced drilling and poor core recovery in places through the mineralized intervals, giving rise to uncertainties in the grade and continuity of mineralization. The historical drilling did not delimit the margins of the silver/gold mineralization. The target horizon containing the La Trini mineralization extends along strike for about 1,500m easterly to the Las Higueras silver prospect where the current owner has identified a further conceptual exploration target of up to 700,000 tonnes. Tumi's management believes that the entire zone covering the La Trini to Las Higueras mineralized zones is prospective for silver/gold mineralization and exploratory work has commenced. The work program will include a first phase program of remapping and sampling of surface outcrops and channel sampling of all accessible underground workings. On completion of this first phase, a large diameter reverse circulation drill program will be undertaken. The drill program is expected to commence in the latter part of this second quarter 2005.
