Marifil Hits Bonanza Silver & High-Grade Copper At Toruel

SPOKANE, WASHINGTON--(CCNMatthews - Nov. 28, 2005) -

DDH-32 Intercepts 6.7 M of 2044 g/t Ag Equiv. and 5.34% Cu

MARIFIL MINES LTD. (TSX VENTURE:MFM) ("the Company") announces its recently-completed Phase 2 drill program has discovered significant silver and copper values in drill holes located near DH-24 at its wholly-owned Toruel project in Rio Negro Province, Argentina. (See Marifil news release of November 14, 2005.) Complete silver results from the first four holes of this 1,350-meter diamond drill hole ("DDH") program all show significant silver values. Although assay results examining copper values have only been received so far for one drill hole, the Company expects further positive copper values based on the amounts of chalcopyrite and tetrahedrite observed in the drill core.

DH-32, located 30 m west of DH-24, cut 6.7 meters grading 2044 grams per tonne silver equivalent plus 5.34% copper, including 2.4 m grading 4283 g/t silver equivalent plus 10.38% copper. (See DH-32 Cross Section and Drill Location Map on Page 2 of this release.)

Assay results are pending on 15 more holes, including DDH-35, which intercepted the same hydrothermal breccia structure cut by DDH-32 at approximately 25 meters greater depth. Preliminary drill results available so far are summarized below:



--------------------------------------------------------------------- SilverDrill Hole From (m) To (m) Interval (m) Equivalent(i) Copper (%)---------------------------------------------------------------------DH-31 58.80 62.40 3.40 436 g/t pending--------------------------------------------------------------------- including 61.10 62.40 1.30 810 pending---------------------------------------------------------------------DDH-3 34.5 41.2 6.70 2044 5.34--------------------------------------------------------------------- including 35.8 37.6 2.40 4283 10.38---------------------------------------------------------------------DH-33 66.6 67.5 1.90 167 pending---------------------------------------------------------------------DH-34 35.0 38.0 3.00 736 pending---------------------------------------------------------------------
(i) The silver equivalent is derived from a silver:gold ratio of 61:1; silver comprises more than 90% of the value.




The Company has completed a total of 49 drill holes during the first two phases of diamond drilling on this important project. These latest results confirm that the Toruel project contains a significant silver-copper resource along with important values in lead and zinc.

Company geologists are now mapping and sampling some of the other large veins on the property including the Ancha Vein (revealed to be up to 8 m wide and 700 m long), the Canyon Vein (10 m wide and 1,500 m long), and the White Goat Vein (up to 30 m wide and more than 1500 m long). An $850,000 Phase III drill program is planned to develop ore reserves in the main Toruel vein and for further testing of some of the other veins on this nearly 35,000 hectare property. All assaying is being done by Alex Stewart & Co. in Mendoza, Argentina. Elements other than silver and gold will be analyzed by ICP at the same laboratory.
