ann: first drill program to test for silver mi, page-48

In regards to the silver or Polymetallic discovery, the 'ASX announcement' on the '20/05/2013' made it very clear that it is 'high grade'. The 'ASX announcement' mentions 'high grade' regularly, I have listed some of them below:

Review Confirms High Grade Polymetallic Cascavel Discovery:

Orinoco Gold Limited (ASX: OGX) is pleased to advise that handheld XRF1 analysis and a complete review of geology and drill core from its Cascavel Project in Brazil, has confirmed mineralisation along strike and down plunge
from the first drill hole (CdP_021 17.6m at 1263gpt silver) which leads the Company to believe that it has made a substantial high-grade polymetallic discovery.

Analysis of the geology, drill core and handheld XRF1 results has resulted in the identification of numerous mineralised corridors containing high-grade polymetallic mineralisation.

Initial geological interpretation concludes that the mineralisation sits in multiple, extensive corridors - the same as that which returned the initial high-grade polymetallic assay.

As a result, Orinoco believes that the assays from these eight holes will return high-grade poly metallic results.

In light of these findings, additional high-grade polymetallic corridors can be expected to be discovered through further drilling and the use of airborne geophysics both within the Cascavel Project and potentially also within Orinoco’s broader Faina Goldfields tenement package.
