In consideration of Will Anglo Sign a Exploration J.V. here is some more interesting info to add regarding the potential
at Sertao as a second mine & processing facility has clearly had considerable evaluation & further exploration conducted
in recent years.


Extracts from 18th Feb 2014
Historical drilling highlights the potential for extensions of the Sertão mineralisation beneath the existing open pit.
Sertão is located 22km south-east of Cascavel (28km by road) along the same shear zone.
Like Cascavel, the hard rock gold mineralisation at Sertão occurs in structurally controlled quartz veins, is generally coarse and plunges at approximately 25-35 degrees to the west.
Intersections including 0.7m @ 48.2 g/t gold (GVD 029) and 0.33m @ 119.6g/t gold (GVD080), which are respectively ~100m and ~750m down-plunge from the pit floor, illustrate the continuity of the structure previously mined at Sertão.
An existing haul road runs between the Antena Mining Lease (which is 5km from Cascavel) and Sertão.
It will require some maintenance before being re-used as a haul road.
historical drill results show that there is clearly the potential to define additional ounces immediately beneath the Sertão open pit and
for us to add a second high grade project to our portfolio with great exploration upside.
The Sertão mine was a very successful high grade producer with strong geological similarities to Cascavel.”

Map of the Sertão open pit. All holes shown on the map other than GVD 080 and GVD 029
(shown on section A over page) were in areas mined as part of Troy Resources open pit operations.
Further holes, not shown on this map, were drilled outside the open pit, and Orinoco is currently compiling this information
for future release.

CROSS SECTION A


Their has been subsequent to this release further D.D. to the West of Sertao that further supports the continuation of
mineralisation to the West & North West of the pit mined by Troy.

Asx Ann 25 July 2018-Extract -As part of this review, theCompany conducted a detailed study of the Sertão Prospect
which has an existing JORC Mineral Resource estimate of 223,111 tonnes at 6.9g/t for 49,268 ounces of contained
gold the Sertão Stage 4 and Stage 5 orebodies were65m and 25m wide respectively and were intensely mineralised
and structurally controlled along the shallow sections
previously mined by Troy.
Analysing the data gathered from the 2015 campaignwith historic data from SML, Troy, WMC and the SRT001 (Yamana) drilling together with theexisting induced polarisation surveyof the projectprovides very strong support for the theory of continuation of the intense mineralisation
along a structurally controlled fluid pathway to the westand north.
Our exploration team assess the findings of this modelling to indicate potential significant extensions of the Stage 4 and Stage 5 orebodies.•

Modelling of this potential orebody indicates that it is "directly accessible" for underground mining from the existing pit directly onto the continuation of the high-grade mineralisation that is present in the existing pit wall and floor.
Some of the historic drill intercepts that have contributed to this model include the following:
STO004 (OGX) 0.5m @7.33g/t FROM 141m
STO005 (OGX) - 4m @10g/t from 126.2m including[email protected]/t from 130.7m

An "IP anomaly "consistent with existing ground geochemistry "has been identified directly to the WEST of the Sertão Stage
4 and Stage 5 open cut pits.
A CIL licence was submitted for Sertao !
ASX -17th August 2108-drill hole OST012 indicate significant high grade westerly extension of mineralisation in the Sertão Stage 4 orebody to the west of previously mined Stage 4 open-cut pit.
OST012 assays were requested to be processed as a high priorityto allow the assays to be analysed with OST001 to confirm the priorities for ongoing drilling program to the west of Sertão - while J.V.. negotiations are continuing with Anglo
Cascavel mine development being pursued chasing high grade narrow vein gold lower- now atlevel 7 whereby the geometry and timing of the faults within the structural history at Sertao is identical to the faults at Cascavel that host the gold mineralisation .
( This is a big statement imo given what was pulled from the TRY pits at 25 Grams Per Tonne Recovered Gold.)
For those interested-Best read in conjunction with initial post containing additional info post #:37665722.

Information compiled for consideration regarding the potential within OGX's tenure as logically Anglo would only be interested if they Anglo believed the potential to pursue exploration was compelling.
Take it or leave it.
