Three chip samples were taken from the exposure. A sample of the hanging wall material comprises approximately 60 cm, extending from a sheared contact with the host rock to a zone of azurite staining. The second sample, 70 cm thick, comprises intact host rock at the core of the vein (possible inclusion in the fault zone – fault tear-out) with development of strong azurite staining. The third, and final sample (65 cm thick), comprises a leached zone with up to 20 cm of copper wad developed along the footwall contact.
The Maribel Drift has been developed on an interpreted splay of the Descubridora Vein and is located approximately 1.45 km from the workings developed on behalf of the Company on the Descubridora Vein. The Drift extends approximately 40 m from the portal along an interpreted splay of the Descubridora Vein. The face exposes approximately 60 cm of a strongly leached, iron oxide zone comprising the vein. A second chip sample, over 1.5 m, was taken of the host rock in the hanging wall (i.e. above) the vein. Textures evident in the face of the drift are tentatively interpreted to suggest vein development may be, in part, through replacement of the host rock within, and adjacent to faults.
Approximately twenty trenches, ranging from near surface excavations to depths to approximately 7 m, having an areal extent between 6 and 200 m 2, have been excavated over the past 10 days by the Optionor on behalf of the Company. Approximately fifteen of the new trenches were excavated in the Sierra de la Gloria area, located approximately 5.5 km south-southeast of the nearest active workings active and/or development on behalf of the Company (see News Release dated February 7, 2013). This work was undertaken to further evaluate the mineral potential suggested by previous work (see results for samples ALGA12RW-001 to 004 and ALGADG-01 to 05 reported in News Release dated February 14, 2013).
The new trenches exposed several small, yet high grade copper mineralized veins, between 2 and 5 cm thick, within leached, oxidized zones up to 1.5 m thick. In addition, several of the veins, as well as the leached, mineralized zones, were documented to thicken dramatically from surface to the base of trenching. In the most extreme example, a 2 cm thick, chocolate-brown vein comprised of completely oxidized iron (goethite) thickened to approximately 30 cm over a down-dip distance of 1 m.
