Xtierra has discovered a new high-grade silver zone at its Bilbao project in central Zacatecas, Mexico.
The company has taken drill-hole CG-4 as part of the geotechnical section of feasibility study for the planned open-pit at Bilbao and has intercepted cost-effective major silver values in a new brecciated fault zone. Stratigraphically, the new target occurs over the high-grade silver targets depending on analysis of the previously announced drilling and occurs nears the south-eastern fringe of the planned open-pit.
This new silver mineralization is present in a brecciated, manganiferous limestone at least 5.70 metres in thickness, from 120.00m to 125.70m depth, and cuts 247 g/t silver in average. This identical prospect is found in drill-hole X-85, which was drilled by Xtierra previously in the main Bilbao resource.
The drill-hole CG4 is present in an unexamined area of the project, 100m to the east of drill hole X-85 and 50m south of drill hole X-41, representing mineralization continuity in the deposit’s south-eastern zone and is expected to adjoin the presently described mineral resource.
Also, the new drilling ,which is inspecting the previously intercepted high-grade silver zone, along the western margin of the Bilbao deposit expanding over a strike length of at least 300 metres will explore this new silver-rich zone situated around 180 metres to the south-southeast. Additionally, Xtierra will drill on numerous geophysical targets and on a new silver-lead geochemical anomaly target at the Ardillas prospect sited 1.5km north-east of Bilbao.
