Intersections At The Encinal Zone - El Cobre Project
VANCOUVER, BC - Almadex Minerals Limited has received assay results from the top of hole EC-17-025, which was collared into newly recognised area of exposed stockwork quartz veining and gold mineralisation in the Encinal Zone of the project. The Encinal Zone is located roughly 3.5 kilometres to the south-southeast of the Norte Zone drilling and 2.5 kilometers southeast of the recently identified Raya Tembrillo Zone of stockwork veining. To date assays have been received to a depth 300.36 meters with assays pending for the remainder of the hole. Significant mineralisation was intersected from the collar.
J. Duane Poliquin, Chairman said, "While we are carrying out a systematic drill campaign to follow-up results in the Norte zone, there are other significant porphyry occurrences on the project that require drill testing most notably the newly identified Raya Tembrillo target. The hole reported today is from the Encinal zone where past drilling intercepted alteration and mineralisation peripheral to a porphyry system. Hole EC-17-025 has intercepted significant mineralisation that is proximal to a porphyry core. We look forward to reporting further results in the coming weeks and months as the programs progress."
The Company has now established trails which can support drill mobilization into the newly discovered Raya Tembrillo target, which is located in the Villa Rica Zone, roughly two kilometres to the south of the Norte Zone. The drill at the Encinal zone will be moved to Raya Tembrillo once some additional holes are completed to follow-up EC-17-025.
The El Cobre Project has a total area of 7,456 hectares and is located adjacent to the Gulf of Mexico, about 75 kilometres northwest of the major port city of Veracruz, Mexico and has uniquely excellent infrastructure. The project area is situated 200 meters above sea level with extensive road access and is located less than 10 kilometers from a power plant, highway, gas line and other major infrastructure. Major power lines cross the property area. Almadex has its full drill permits from SEMARNAT and has land access agreements in place. The land ownership is private over most of the project area, has previously been cleared and is used for local agricultural purposes.
The four copper-gold porphyry targets currently known within the El Cobre Project, Encinal, El Porvenir, Norte and Villa Rica are defined by distinct Cu-Au soil anomalies, discrete, positive magnetic features and a large IP chargeability anomaly. The largest target area is the Villa Rica zone which has not been drill tested. Limited past RC and diamond drill testing at Encinal, El Porvenir, and Norte has returned wide intercepts of porphyry copper-gold and narrow zones of intermediate sulphidation epithermal gold-silver vein mineralization, with selected intercepts.
El Porvenir Zone: Drilling has demonstrated that the system persists at least to 400 m depth. Significant copper and gold grades were intersected such as 0.16% Cu and 0.39 g/t Au over 290 m in hole DDH04CB1. In addition, hole EC-13-004 intersected 0.23% Cu and 0.36 g/t Au over 106 m, to a depth of 504 m, again indicating potentially significant mineralization at depth.
Encinal Zone: Past drilling in the area includes the 1998 RC hole CB5 which intersected a highly altered breccia pipe containing fragments of stockwork veining and porphyry mineralisation across which 18.28 meters returned 1.42 g/t Au and 0.10% Cu. The breccia pipe occurs in a large alteration zone, IP chargeability high and magnetics low which has not been tested to depth. On July 1, 2016, Almadex reported results of drilling at Encinal, which were consistent with the interpretation that the drilling was located in a zone marginal to a potential copper-rich portion of the porphyry system. Hole EC-17-025 is to the north of this past drilling.
Norte Zone: All five holes drilled in the Norte Zone prior to 2016 intersected porphyry-style mineralization. Hole 08-CBCN-022, one of the deepest holes drilled at Norte in 2008, returned values of 0.14% Cu with 0.19 g/t Au over 259 m and 08-CBCN-19 intersected 41.15 meters averaging 0.42 g/t gold and 0.27% copper to the end of the hole at 187.45 meters. Drilling in 2016 and 2017 has been designed to test this zone to the south and at depth.
In addition several anomalous areas remain untested by drilling, including the Villa Rica Zone, a roughly 2.5 kilometre by 1 kilometre area defined by a strong north-northwest trending magnetic-chargeability high and associated copper-gold soil geochemical anomaly. Recently significant new gold porphyry mineralisation was identified in outcrop at the Raya Tembrillo target within the Villa Rica zone.
