Orinoco Gold Limited announced that an extensive review of the exploration data available for the Silver and Base Metal anomalies first identified in 2013 is being conducted. The data has been gathered from five years of regional field mapping, historical data, rock chip sampling, and drill core results and reaffirm the huge potential of the system. Although the initial drilling results were spectacular, the companies focus on developing Cascavel for its gold meant much of the silver focus has been put on hold. Whilst the range of exploration targets on Orinoco's substantial tenement package could warrant a significant exploration budget, their`Back to Basics' approach will focus on a modest programme to initially test silver and to better understand Cascavel's brownfields gold potential including a 1km deep hole. This work will be led by their Head Geologist Marcelo de Carvalho and his team. Their first port of call will be the restart of the Cuca gold zone which sits directly underneath this very rich silver intercept. Dewatering of the Cuca shaft 350 metres northwest from the Cascavel Mine entrance began last week and should be operational in February to provide Orinoco with a proposed 5 x 1 tonne batch of mineralised vein and alteration samples from the Cuca zone and potentially access to the silver zone (Cascavel Dolomite) that sits above it. They are very excited about Cuca's potential to provide Cascavel with an extra source from high-grade mineralized veins to the mill from where previous bulk sampling graded 27.2 g/t gold from a 2.5 tonne batch announced on 14 May 2014. To the south of Cuca they believe sits a long strike length of new silver targets where the thicker Cascavel Dolomite is crossed by mineralised faults. Whatever the theory, They would note that any Junior explorer with the silver grades illustrated below would be very excited with those alone. Four years ago, the drilling program was executed to define the Cascavel gold mineralization and unexpectedly intercepted the silver rich/poly-metallic mineralization. These were announced in 2013 on the 8thMay, 20th May and the 11th of July. Best results for silver from the initial 22 hole program were: CDP_021: 17.56m at 1,292.4 g/t Ag & 11m at 0.25% Cu from 101m; CDP_025: 25.0m at 39.2g/t Ag: including 3m at 97.2g/t Ag from 114m; CDP_031: 4.4mn at 760.3g/t Ag: including 1.05m at2,510 g/t Ag from 157m; CDP_014: 4.7m at 58.6g/t Ag: including 0.85 at 236g/t Ag from 162m. These grades and intersections would normally warrant a dedicated exploration programme with 20,000+ metre follow up drill campaign but they are currently considering a more modest 5,000 metre programme that also includes a 1km deep hole at Cascavel. They hope the `Back to Basics' milling method to processing their high-grade gold will fund this programme in the 2nd quarter of this year. Since Orinoco's journey began in 2012 only 8,000 metres has been drilled in the immediate Cascavel Mine area that now forms part of the Mestre, Central and Northern zones for gold production. This was importantly only designed at the time to define the Cascavel/Mestre/Cuca gold mineralisation and not to specifically test the silver, copper and tungsten in the Cascavel Dolomite. In reality, little if any work was conducted on Cascavel and Tinteiro's gold, silver, copper, cobalt and tungsten potential, which the company regards as significant. Much thicker silver targets may sit to the south of Cascavel Importantly they want to test if these high-grade silver zones are formed in much thicker zones of the Cascavel Dolomite. About 350 metres southwest from the original high-grade silver hole, sits a much thicker zone of the Cascavel Dolomite that can host the poly-metallic mineralization similar as at the Cascavel Mine area. The temptation of course is to look for the probably igneous source that feeds those faults and creates these high-grade silver shoots. However, that is a much bigger exploration programme, beyond their `Back to Basics' budget for now and will hopefully be a part of the proposed 70/30 AngloGold/Orinoco JV. Obviously, a lot more work needs to be carried out before they consider if this is truly prospective but the presence of thicker Cascavel Dolomite intercepted by the late E-W Tinteiro faults and if those faults are carrying the same mineral association as the ones at theCascavel Mine area, there may be potential for more mineralized zones.
