Vena Resources Expands Drill Program at Azulcocha PDF Print E-mail
Tuesday, 22 March 2011 22:27

Vena Resources Inc. (TSX: VEM, LIMA: VEM, Frankfurt: V1R, OTC-BB: VNARF, Xetra: V1R.DE) announced that the ongoing regional exploration program at Azulcocha to increase resources has identified an additional three target areas near the existing mine infrastructure that warrant immediate testing. 

Any successes in the near mine program could be fast tracked to development through extensions of the existing underground workings. The three target areas are shown on the attached map and described below.

Azulcocha Mine - West Fault Extension

The western end of the Azulcocha ore body is terminated by a left-lateral strike slip fault that strikes northeast – southwest. The displacement on the fault has been calculated to be about 100 metres. A program of two holes totaling 680 metres is planned to test for a blind western extension of the ore body beneath the over thrust Pucara limestones.

Azulcocha South - Mantos

Two semi-parallel mineralized mantos have been identified within the Pucara limestones that form the hanging wall of the Azulcocha mine. The mantos are karstic breccias with associated jasperoid that have been developed in dolomotized limestone beds between the Fierromina and and Laguna cross faults. The mantos are from three to 10 metres thick and approximately 650 metres long. The surface exposures have been oxidized but give highly anomalous values in zinc/ lead and silver with individual grab samples up to 11% zinc. A series of 10 short holes totaling 1,345 metres are planned to test the mantos for economic mineralization at depth.

Azulcocha East – Covered ZN/ Mn Targets

Trenching in covered areas to the east of the mine has exposed the Cochas-Gran Bretana fault. The trenches have been successful in revealing alteration in the footwall rocks similar to that at the mine. Geochemical sampling has outlined three areas with a similar footprint to that at the mine with high primary values of copper/ silver/ gold in the footwall tuff/ sandstone sequence and high values of zinc/ barium/ manganese in oxidized zones within the fault zone. Additional trenching is presently being completed to fine tune the targets prior to drill testing.

Miguel Sanchez, the Azulcocha mine project manager, stated: “Recent exploration at the Azulcocha mine was confined to underground workings and did not include surface diamond drilling to test favorable structures outside of the immediate area of the known ore body. As a consequence we have a great opportunity to search for additional resources in the near mine area that can be fast tracked to production and could add significantly to the profitability of the operation.”
