Marifil Reports Drilling Update on Amarillo Project
Spokane, WA US, April 21, 2008 /FSC/ - Marifil Mines Ltd. (MFM - TSX Venture, MFMLF - OTCBB_Pink_Sheets), is pleased to report that drilling is ongoing on the Amarillo project in San Juan province, Argentina by the company's joint venture partner, ATW Venture Corp. Two core holes have been completed and a third one is in progress. To date, a total of 1,100 meters have been drilled. Assays are pending for all drill holes and select samples for hole ATW-AM-06 have been sent for rush assay.
A drill hole location map of the 2008 Amarillo Exploration Program is available on the Marifil Mines website.
The first drill hole of the year, ATW-AM-05 ("F" on drill hole map), was collared at the bottom of Quebrada Poposa. This was a vertical hole drilled to roughly 400 meters. It was designed to test for potential primary copper mineralization at depth. The hole drilled through a thick sequence of weakly altered to fresh dacitic tuffs and pyroclastics rocks. At the bottom of the hole fragments of altered quartzite are observed in the clastic unit. This hole appears to be collared in a down-dropped block of young, post mineral volcanics and did not intersect mineralized lithologies.
ATW-AM-06 ("SM-2" on drill hole map) was drilled on the northern portion of the alteration halo to test for gold mineralization down-plunge along the intersection of northwest and north-northeast trending structures. The hole had a bearing of S80 degrees W and was drilled at -60 degrees. The hole encountered vuggy quartz/pyrite veining in various places in the top part of the hole. These veins are similar to those observed on surface in the road cuts and which are reported to have high gold grades locally. Further down hole there is a marked increase in silicification of dacitic/andesitic dikes and of the surrounding quartzite with disseminated pyrite from three to five percent and locally up to 10 percent. Silicification appears to be overprinting earlier alteration events possibly argillization and bleaching. Additionally, there is also a quartz/pyrite +/- sericite stockwork event that in general increases with depth. Quartz pyrite veins up to two inches (five centimeters) are observed locally. In sections, the stockwork is very robust and sulfide content (py) in short sections of the core can be >30 percent. In general, very little copper mineralization is observed, with only occasional minor chalcopyrite noted in veinlets. This hole was drilled to a depth of 525 meters. Select samples from down-hole have been rushed for assays.
The current hole, ATW-AM-07 ("H" on drill hole map) is collared on Esperanza Hill. It is being drilled due south at -60 degrees. This hole is designed to test at depth, outcropping copper mineralization further up hill. The top 100 meters contain sporadic copper mineralization in various lithologies. Currently, the hole is approximately at 190 meters.
Mapping and sampling has been ongoing on the northeast portion of the system, the Sericite Target. There, quartzites are host to a sericitically altered quartz porphyry dike. Quartzites near the dike exhibit quartz stockwork veining and moderate hematite staining. Assays from this area are pending.
Mapping and sampling will also be undertaken at the Filo Colorado Target to gain further understanding of the controls to gold mineralization there.
A fourth hole is contemplated pending results from hole ATW-AM-06 ("SM-2") and surface samples from the two areas mentioned above.
