TSXv - TM Frankfurt - TUY OTCBB - TUMIF VANCOUVER, Dec. 12 /CNW/ - Mr. David Henstridge, President, is pleased to announce that fieldwork has resumed at La Trini gold/silver project, Mexico. An historical resource estimate was made at La Trini by National Lead in 1980 based on the results of 26 diamond drill holes and calculated using vertical cross sections constructed through the mineralized blocks using a spacing of 45m. A mineral resource of 1,262,000 tonnes at a grade of 1.24 g/t gold and 125 g/t silver was calculated. Although considered relevant the reader is cautioned that this resource estimate is historical in nature, does not comply with the guidelines of National Instrument 43-101 and should not be relied upon. Further, the estimate has not been verified by the Company's qualified person. The historical drilling did not delimit the margins of the gold/silver mineralization. In September, the Company announced the results of an initial 15 hole reverse circulation drill program focused on the central 200m of a rhyolite porphyry host. Surface, underground and drill evidence suggests that the rhyolite porphyry, hosting the disseminated gold/silver mineralization, is an intrusion rather than a volcanic. The rhyolite dips shallowly to the north has been traced over a distance of 1 km east-west and remains open along strike and down dip. Fourteen of the drill holes intersected mineralization. Using a cut-off grade of 30 g/t silver, composite results ranged from a minimum width of 2 m to a maximum of 38.6 m, with a best result of 18.3 m at a grade of 3.1 g/t gold and 150 g/t silver in drill hole TRRC-6 (see press release dated September 29, 2005). Within an area of 200 m by 100 m the holes intersected disseminated gold/silver mineralization over an average 14 m thickness, and the mineralization remains open both along strike and down-dip. An induced polarization (IP) and resistivity survey, comprising 17 north-south traverses and centered on the known mineralization, has disclosed an extensive zone of chargeability and resistivity anomalies roughly parallel to the projection of the rhyolite porphyry which hosts the mineralization. Several large and strong chargeability anomalies with coincident surface geochemical anomalies were defined in the survey outside of the drilled area and will be tested in the next drill program. To better define the westerly extent of the mineralized porphyry, the grid is being extended a further 700 m west of the drill area for additional mapping and soil sampling. The previous geochemical survey yielded anomalous results in silver and other metals over a 500 m length which is open to the west. A second phase reverse circulation drilling program is planned for early 2006 to test the extensions of the host rhyolite both to the east and west as well as test the significance of some of the geophysical anomalies.
