TORONTO, Nov. 27, 2017 /PRNewswire/ – Orvana Minerals Corp. (TSX:ORV) (the “Company” or “Orvana”) is pleased to announce the results of a twelve month infill drilling campaign during fiscal 2017 at its El Valle and Carlés Mines in northern Spain.
The drilling program consisted of 209 diamond drill holes (“DD”) totaling approximately 23,000 meters (“m”) at the El Valle Mine and 45 DD holes totaling approximately 2,700 m at the Carlés Mine. A core objective of the drilling executed during fiscal 2017 was to generate the information required to substantially de-risk the fiscal 2018 mine plan overall, and also to lay the foundation for future in-mine exploration targeting expansion of the mineral resource base.
Assay intersections relating to this drilling program are provided in this news release and include the following highlights:
El Valle Mine
8.29 g/t Au and 1.92% Cu over 9.6 m in the Black Skarn Oxide area, which remains open to the west. 64.27 g/t Au over 4.9 m in the East Breccia zone, an oxide orebody drilled from surface and located to the northeast of current mine development.
12.54 g/t Au over 10.2 m in a skarn orebody located in the Carlés Northwest area, which contains higher than average gold grades and which remains open at depth.
Jim Gilbert, Chairman and CEO of Orvana stated: “We are very pleased with the results of the infill drilling activities at the El Valle and Carlés Mines during the past fiscal year. One of our stated objectives in fiscal 2018 is to improve grade control of the ore coming from our Spanish operations by targeting the development of higher-grade oxide areas, which will, in turn, positively impact our overall unitary costs. The successful infill drilling campaign completed in fiscal 2017 means that we are now well-positioned to achieve this objective, and also to increase mineral reserves and resources within the new higher-grade Black Skarn Oxide areas identified by the program.”

The results reported in this release are from three areas (1) Black Skarn Oxide (“BSO”), an oxide zone located in the upper part of Black Skarn towards the west, (2) East Breccia (“EBX”), an oxide zone located to the east of the El Valle open pit; and (3) Carlés Northwest (“CNW”), a skarn zone located at depth (Figure 1).
Drilling in these areas was undertaken with the objectives of (i)
