Marifil Reports Preliminary Assay Results From San Roque Gold Project

Trench Sampling Returns 20 m @ 2.94 g/t Gold

SPOKANE, WASHINGTON--(CCNMatthews - Nov. 9, 2006) - MARIFIL MINES LTD. (TSX VENTURE:MFM)("Marifil" or "the Company") announces preliminary results from trench sampling on its San Roque gold project.(See Marifil News Release of September 6, 2006.) A few gold and all silver analyses are still pending. The Company completed 27 trenches totaling 442.2 meters (m) and took 235 bedrock samples from four targets on the property (A map showing the target locations is available at: Http://www.marifilmines.com/s/SanRoque.asp).

Strong gold mineralization has so far been demonstrated on the two targets from which assay results have been received. This gold generally comes from structurally controlled zones of silicified breccias cut by stockwork quartz veinlets stained by iron oxides within a volcanic (rhyolite) host rock. Results for Target 2, located approximately 2000 metres (m) southeast of Target 1 and 1500 m northeast of Target 3, include:



- T-2-1 cut 8.3 m grading 1.74 grams per tonne (g/t) gold
-- including 2.3 m grading 3.57 g/t gold.

- T-2-4 (located about 50 m to the southwest) cut 20 m grading
2.94 g/t gold
-- including 4.0 m at 12.3 g/t gold.


The Company believes this is important mineralization that deserves further drill testing following additional trenching to determine its lateral extent.

Target 1 contains a zone of silica enriched structures. Trench sampling results here include:

The mineralized zone at Target 1 is cut by eight trenches along a strike length of about 300 meters. Mineralization exposed by these trenches shows a continuous linear structure zone comprised of sub-parallel quartz veins and silicified breccias containing occasional specks of visible gold, iron oxides, and copper oxides, which appears to be increasing in width and gold content going northward. The gold mineralization of this feature seems to be directly related to copper mineralization.

T-1-1, the northernmost trench, missed its target. Apparently, the mineralized zone is laterally offset a short distance by a minor fault. Prospecting in the alluvium covered area to the north of T-1-1 found numerous cobbles and boulders of copper-stained quartz vein and silicified breccia strewn over an area some 100 m wide by more than 300 m long. As the landscape is generally very flat, geologists conclude the mineralized float must be coming from nearby structures hidden under the alluvial veneer.

On a third prospect, Target 3, two trenches cut several one- to two-meter wide quartz veins for which sample assays are pending. A fourth target has been identified where pebbles and cobbles containing significant gold values are dispersed in the alluvium.

The San Roque property comprises 12,705 hectares and is located 56 kilometers east of San Antonio Oeste, a port on the Atlantic coast, in Rio Negro Province, Argentina. It lies on an extensive alluvial covered plain where some low-lying outcrops of silicified rhyolites protrude the cover. Geologic mapping requires extensive use of float tracking and trenching, an approach that has already identified several targets. Additional mapping and trenching are expected to begin later this month.
