Sunstone Metals Ltd. announced more bonanza drilling results from the Espiritu silver- gold discovery within its Bramaderos project in Ecuador. Assay results and geological interpretation from hole ESDD006 show multiple silver-gold bearing structures with various orientations (Tables 1, Figures 1, 2, 3) with high-grade mineralisation including: 3.75m at 11.8g/t silver, 1.54g/t gold from 102m, 0.4m at 355g/t silver, 0.36g/t gold, 3.55% zinc from 173m, 0.5m at 187g/t silver, 1.44g/t gold from 206m, 0.5m at 550g/t silver, 0.26g/t gold from 278m, 0.5 at 93g/t silver, 0.68g/t gold, 2.45% zinc from 313m. Drilling of hole ESDD008 has just been completed at 359.97m and has intersected altered and mineralised intervals that deliver increasing confidence in the interpreted geometry and demonstrate that the Espiritu discovery has the potential to be a large system with currently over 200m of strike containing local bonanza silver grades. On a gold or silver-equivalent basis, the intersections reported are very significant. Drill hole ESDD009 has been commenced and is targeting an area 250m south of ESDD008. Drilling to date has only tested to a depth of 250m below surface in two locations at Espiritu. Evidence of multiple lodes means there are several opportunities to follow-up bonanza grades across the area drilled to date. Narrow high-grade zones and intervening lower grade zones can be bulked and outline larger mineralised bodies. Both concepts are being explored - high grade narrow veins and larger lower grade systems. Exploration has commenced at El Palmar, with historical drill holes being re-logged and the upper zones that were not previously assayed have now been sampled and assayed. They have returned gold- copper mineralised intervals with up to 0.9g/t gold and 0.26% copper over individual samples of 1.0m. Work to date has focussed on stakeholder engagement, review and sampling of historical drill core, and planning for a ground magnetic survey which will commence in the next few weeks. It is expected that drilling can commence during March. As stated above, the upper 33-51m of each of the 3 historic drill holes from 2012 had not been previously sampled and assayed. Sunstone has now done this, and the results returned encouraging intervals of gold- copper mineralisation, adding to the previously defined mineralised areas. Importantly, thin younger cover intersected in drill core from surface that is not mineralised masks the porphyry mineralisation hence limiting significantly the surface expression of the El Palmar system. New intersections from the recent sampling of historic drillholes include: EPD-02: 35.4m @ 0.34 g/t Au, 0.18% Cu from 8.12m, adding to the 34.5m historical intersection of 0.31g/t gold and 0.16% copper. EPD-01: 16.9m @ 0.20 g/t Au, 0.13% Cu from 12.89m, adding to the 186m historical intersection of 0.33g/t gold and 0.16% copper.
