Almaden Minerals Ltd. (TSX:AMM) (NYSE Amex:AAU) has announced all outstanding assay results from its 2010 Ixtaca project drilling program.
These holes further confirm the continuity of mineralisation and veining with broad intersections such as 136.92 m of 1.47 g/t gold and 36.3 g/t silver including 43.96 m of 3.1 g/t gold, 62.3 g/t silver (hole TU-10-10), 165.07 m of 0.83 g/t gold and 50.8 g/t silver including 45.01 m of 2.37 g/t gold and 157.4 g/t silver (hole TU-10-12) and 203.65 m of 1.01 g/t gold and 44.3 g/t silver (Hole TU-10-11). The drilling also intersected high-grade vein zones such as 0.87 m of 23.29 g/t gold and 34.6 g/t silver (hole TU-10-10), 3.17 m of 10.53 g/t gold and 585.7 g/t silver (hole TU-10-12), 1.77 meters of 48.98 g/t gold and 1391.7 g/t silver (hole TU-10-11) and 2.74 meters of 8.17 g/t gold and 710.1 g/t silver (hole TU-10-14). The furthest holes to the southwest, TU-10-7 and TU-10-8 both drilled on the same section, intersected a shaley unit which appears to have been a poor host to veining as less veining was noted. Several holes deviated significantly from their planned orientation including holes TU-10-9, TU-10-12 and TU-10-13. TU-10-9 could not be completed due to mechanical problems with the drill and was stopped before getting to where the main vein zone was anticipated. Hole TU-10-13 deviated to the north as well as steepening significantly and did not cross, and may not have reached, the main vein zone.
J.D. Poliquin, Chairman of Almaden commented, "Drilling to date on the Ixtaca zone shows good continuity of mineralisation in both horizontal and vertical dimensions. We are very pleased with the results and eagerly anticipate commencing 2011 with a drill program designed to continue testing the strike extent and vertical continuity of the Ixtaca zone, which appears to be marked by strong IP and gold in soil responses for at least a kilometre northeast of present drilling."
The Ixtaca zone is a blind discovery with little surface manifestation and the 2010 drill program was successful in confirming its general orientation. The continuity of the vein zone and gold/silver grades were confirmed within the discovery area. The zone of veining is thought to have a north-easterly trend and, while true widths still cannot be calculated with confidence, the overall vein zone is thought to be vertical to subvertical, possibly dipping to the south. The drilling completed to date has traced mineralisation over roughly 300 meters along this northeast trend. Based upon observations at surface and of core as drilling progresses, there seems to be a variety of veinlet orientations within the vein zone, including one along bedding striking roughly 150 to 170 degrees and one almost perpendicular to bedding striking roughly 50 to 70 degrees. Holes TU-10-2 through TU-10-6, TU-10-9, TU-10-11, TU-10-13 and TU-10-14 were drilled sub-parallel to bedding at 150 degrees azimuth. While this orientation crosses the vein zone perpendicularly, management is reviewing if this drilling azimuth may in fact be parallel to a mineralized vein set. Holes TU-10-1, TU-10-9, TU-10-10 and TU-10-12 were drilled at 100 degrees in order to test intersection angles with different vein sets. Induced polarization ("IP") geophysics was conducted over the Ixtaca zone in 2010 as well as extensive soil sampling. The geophysical and geochemical data indicate that coincident IP chargeability and gold in soil highs, which may represent the vein zone, continues to the north and south from the area drilled. These data also show that the vein zone, which has a northeast orientation in the vicinity of the drilling, may change to a more north-south orientation away from this discovery area. Further to the south thick ash may be masking the geochemical soil response of the vein zone. To the northeast the zone has been traced with strong coincident IP chargeability and soil geochemistry for at least a kilometre beyond hole TU-10-6, the furthest northeast hole drilled to date. The 2011 drill program will focus on testing the strike extent of the vein zone both to the north/northeast and south/southwest. The 2011 drill program is scheduled to commence in late January with two drill rigs, to be expanded as necessary.
Morgan J. Poliquin, Ph. D., P. Eng., the President and CEO of Almaden, and a qualified person ("QP") under the meaning of National Instrument 43-101, reviewed the technical information in this news release. The analyses reported were carried out at ALS Chemex Laboratories of North Vancouver using industry standard aqua regia, ICP and fire assay techniques. Blanks, field duplicates and certified standards were inserted into the sample stream as part of Almaden's quality assurance and control program which complies with National Instrument 43-101 requirements. Gold equivalent ("AuEq" or "Gold Eq.") and silver equivalent ("AgEq" or "Silver Eq.") values were calculated using silver to gold ratios of 50 to 1. Intervals that returned assays below detection were assigned zero values. Metallurgical recoveries and net smelter returns are assumed to be 100% for these calculations. Registered geologist Jim Lunbeck, a QP under the meaning of NI 43-101, will be the QP and project manager of Almaden's 2011 Ixtaca program.
