This polymetallic Sn-Zn-Ag (Tin-Zinc-Silver) project is located in the west-central region nof Bolivia, 60km southeast of the city of Oruro, in the Potosi department. The 2 sq-km property encompasses the historical open pit and underground workings from Spanish Colonial times, which exploited the deposit on a minor and limited scale.

The mineralisation is hosted within a window of Silurian age (423 – 419 Ma) clastic sediments comprising interbedded and layered units of greywacke / sandstone (Scc), as well as interbedded sandstone, siltstone, and shale units (Sll – Sun). The Silurian aged sedimentary rocks which host the mineralisation are unconformably overlain by volcano-sedimentary and pyroclastic ignimbrites (Tvm) of Cenozoic age (66 – 0 Ma), with dacitic to rhyodacitic compositions across much of the surrounding area.

The Porvenir polymetallic Sn-Zn-Ag (Tin-Zinc-Silver) project is located in the west central region of Bolivia, 65km southeast of the city of Oruro, in the Oruro department (Figure 1). The 11.25 sq-km property encompasses historical near surface open pit and underground workings, which exploited the deposit on a limited scale. The mineralised structures were primarily exploited for their high-grade Zinc (Zn) content.

A historical drill program was carried out by DOWA Mining, which included the completion of 88 diamond drill holes, for a total of approximately 25 000 m. Sporadic and inconsistent sampling of the drill cores indicated two distinct zones of polymetallic mineralisation, which include a central zone with elevated Sn as well as Zn mineralisation, as well as a Zn dominant, with minor Sn occurences in the NE portion of the property. It should be noted that selective sampling for high grade Zn mineralisation was carried out, and as such, sampling intervals are inconsistent due to entire drill cores not being sampled
